FROM THE EDITORSNo Limits began as a small group of students who met to share and dis-
cuss articles relating to scientific discoveries that they were interested
in. Eventually, this passionate group of students, under the guidance
of Mr. Jim Morrill, became a magazine and saw its first publication in
1988.
Besides his involvement with No Limits, Mr. Morrill’s contributions to
the Hotchkiss community have been numerous. From the establishment
of Eco Day to the day to day teaching of AP Biology, Mr. Morrill’s great-
est addition to Hotchkiss is our AP Environmental Science Curriculum,
which he single-handedly introduced to this school. He leaves with us
a legacy of one of the school’s most distinguished science faculty.
With Mr. Morrill as the club advisor, No Limits grew and flourished
for over 25 years. But at the same time, the magazine never strayed far
from its original intentions “to arouse your interest in science,” as Victor
Chu ’89, the first editor, put it. Mr. Morrill helped to foster an environ-
ment where people interested in science at any level could just come
and write about their passions and share it with the community.
As time passed, the activity of the magazine diminished and publi-
cations often strayed away from the original purpose of the club. This
issue marks the beginnings of a rebirth of the club. With this, we hope
to bring No Limits into the 21st century while still retaining much of
the club’s ideals that were fostered under Mr. Morrill.
Our mission statement is to “Bridge the gap between classrooms
and the real world, humanities & science, advanced student research-
ers and beginners, and much more.” To accomplish this while still keep-
ing the spirit of the magazine alive, we will be extending the breadth
of our articles beyond science to the fields of technology, engineering,
and mathematics. We will be concurrently publishing the print edi-
tion as well as an online edition to make it accessible to anyone. New
articles will also be posted to our online blog and on our Facebook
page so as to really share our passions and “arouse your interest in
science” as readers.
Of course, none of this would have been possible if it weren’t for
the leadership of Mr. Morrill. Thus, with much pride and gratitude, the
No Limits staff would like to dedicate this issue to him as an honor of
his significant contributions to not only the magazine itself, but also
the Hotchkiss community.
We hope you enjoy!

SCIENCE @ HOTCHKISS
No Limits • Fall 2012 • 5
n the early hours of September 30th, 2012, the
Science Club headed down to the New York
Hall of Science in Queens, NY to attend the
annual World Maker Faire. This is an event that
“celebrates arts, crafts, engineering, science projects
and the Do-It-Yourself (DIY) mindset”. Every year, the
world’s makers, inventors, engineers, artists, scientists,
and hackers all gather at this space to showcase their
work. In addition to strolling around to many exhibits,
the students also had a chance to participate in hands-
on workshops and demonstrations. In the auditorium,
names such as Stephen Wolfram and David Pogue
educated visitors about the uses of Mathematica, a
computer algebra system, and scientific education in
public television.
“It was a way for me to see all of the different cool
projects that people around the world are working
on,” said Franton Lin ‘14, the co-head of Science Club,
“we really hope for the Maker Faire to become a great
introduction trip to the club, and get people psyched
about science in general.” □
Science club meets every Friday from 6:30-7:30 PM in the Science Building. The club heads are Eric Li ‘13 and Franton Lin ‘14 advised by William Fenton.

For the month of July this past summer, a group of 9 Hotchkiss
students went to Rensselaer Polytechnic Institute. There, they
lived in dormitories and did research in the labs of different pro-
fessors. For this issue, we asked each of them to discuss their
experiences working in a lab environment.
Jessica Chen ‘13I studied the ability of the freshwater fern Azolla to uptake and
metabolize estrogenic compounds from the water. It was im-
portant to environmental issues because phytoremediation is
a promising and uninvasive way to remove dangerous environ-
mental pollutants from watersheds and aquifers.
Emily Silva ‘13This summer I worked in Dr. Corr’s lab at RPI with a masters
student, Hsin Dat Li. I was working in Biomedical engineering on
growing tendon fibers. We tested different variables to find the
optimal conditions and best methods for successfully growing
the fibers. Although I will not be able to continue the research
because I do not have the resources away from RPI, I had an
amazing experience. Everything was exciting, even the simple
tasks, because I felt like I was doing something important. I defi-
nitely plan on seriously continuing science in college, and hope-
fully pursuing a career in the sciences.
Meghana Koduru ‘14I worked in Dr. Patrick Maxwell’s lab on aging yeast cells. We es-
sentially gave the yeast cells a certain amount of food to start
with and once they ran out, they stopped growing. At this point
we counted how many cells were still living and also how many
could grow to form colonies if given more food. Aging yeast cells
help us understand how different animals age because there are
many similarities in the genome of yeast and mammals.
Dou Dou ‘13I worked in the Lakshmi lab researching on Photosystem ll in the
cells of plants, and in a bigger context of bio-solar energy trans-
duction study. We also worked on synthesis of the manganese
water-splitting center, EPR(Electron Paramagnetic Resonance),
and the inhibition of oxygen evolution in PS ll.
Austin Kim ‘13I worked on a biomedical engineering project that studied the
effects of alginate-based hydrogels to mitigate spinal cord
injury. In this study, four types of hydrogels prepared with bovine
serum albumin (BSA) were monitored for BSA release in artificial
cerebral spinal fluid (aCSF) over the course of two weeks. The
gels are injected onto a well plate through a syringe in order
to replicate the administration of injectable alginate hydrogels
in situ. A major part of this study was to apply the release of
BSA as a model for the release of small interfering RNA (siRNA).
siRNA works in the RNA interference pathway where it prevents
the translation of certain proteins, effectively “silencing” them.
A final goal of this project is to eventually have the hydrogels
carry siRNA that will use its gene silencing properties to block
synthesis of proteins such as GFAP and disrupt formation of the
glial scar to enhance regeneration outcomes.
Eric Li ‘13My research at RPI involved the effective transformation of Bacil-
lus megaterium using electroporation. I worked under Nicholas
Marchand in the lab of Cynthia Collins. Together we attempted
to explore the method of using electroporation to insert an en-
fuvirtide plasmid into the cell. Enfuviritde is an HIV inhibitor, and
the point of this research would be to find a cheaper more ef-
ficient way of producing HIV medicine rather than the currently
expensive treatment regimen. Electroporation involves applying
a high voltage shock to the cell, opening microscopic pores and
allowing the plasmid to enter the cell.

Sejin Park ‘13My research had a very application-oriented goal: to redesign a
sequence of peptides that is used to detect the onset of acute
myocardial infarction, a lethal heart condition. To produce pep-
tides with better affinity to Troponin I, the protein that needs to
be detected, I took the single amino acid mutagenesis approach,
a technique of substituting an amino acid in the sequence with
other naturally occurring amino acids. After synthesizing, print-
ing, and screening peptides, some of the new sequences were
found to perform better than the original wildtype sequence. In
the long run, my research will be helpful in understanding more
about protein-peptide affinity on the amino acid level. I have
learned not only how to use many specific scientific instruments,
but also important lab techniques and approaches in research
and engineering in general.

Priyanka Sekhar ‘13I studied stem cell alignment and differentiation during my time
at RPI. The purpose of my project was to find a more efficient
way to culture stem cells for applications in the field of tissue
engineering. I used micropatterned surfaces to direct the growth
of the C2C12 cells. I then looked at deviations from the pattern
(compared to the control) to determine which micropatterned
surface and what conditions allowed for the most efficient and
directed stem cell growth.
Peter Moon ‘13I studied processes in photosynthesis. My lab focused on the ac-
tivity of the protein complex Photosystem II (PSII) and, specifical-
ly, a cubane manganese-based structure within this complex that
oxidizes water. My work involved the synthesis and purification
simplified versions of this structure, bonded to terpyridine mol-
ecules, to be studied via Electron Paramagnetic Resonance (EPR).
Analysis of these EPR studies allowed us to observe the effects
of the bonded ligands on the efficiency and structure of the syn-
thesized manganese compounds and compare the results to EPR
studies of the naturally occurring manganese catalysts in PSII.
r. George F. Cahill Jr. ‘44, a prom-
inent Hotchkiss Alum in the
field of medicine, passed away
on July 30, 2012 as a result of complica-
tions due to pneumonia at the age of 85.
He was an unsurpassed diabetes expert
who clarified the role of insulin in human
metabolism, especially during starvation.
Dr. Cahill entered The Hotchkiss School
in 1940 barely 13, the youngest in class.
He immediately distinguished himself
as a bright scholar, receiving the Phillips
Prize for excellence in plane geometry
as well as being the head of the Chem-
Physics club. After receiving his BS in
biology from Yale University, he complet-
ed medical school at Columbia College
of Physicians and Surgeons, where his
father was on the faculty as a uro-
logic surgeon. At the Peter Bent Brigham
Hospital (now Brigham and Women’s),
Dr. Cahill began lifelong research on the
metabolism of glucose and amino acids
during feeding and fasting, as well as in
obesity and diabetes. His studies set forth
many of the tenets that form the basis of
our classic understanding of these pro-
cesses, said Dr. C. Ronald Kahn, the chief
academic officer at the Joslin Diabetes
Center in Boston, where Dr. Cahill was
research director from 1962 to 1978.
During human starvation, the body
initially uses glucose as its main fuel if it
is available. If glucose supply is depleted,
insulin is secreted to break down gly-
cogen into glucose. Dr. Cahill’s research,
which often involved test subjects such
as hibernating bears or divinity students
who were paid to fast for a week, shed
light on the next step of metabolism. He
explained that a drop in level of insulin
leads to breakdown of fatty acids into
ketones, which can cross the blood-brain
barrier and feed the brain as an alterna-
tive fuel. His studies revealed that insulin
is the “primary mover” in determining
human starvation, which interestingly
parallels a diabetes patient, who lacks
insulin, and a starving person, accord-
ing to Dartmouth biology professor Lee
Witters.
Dr. Cahill also found the later stages of
prolonged starvation, in which the body
breaks down protein from the liver to use
as a fuel. This can be life-threatening as
it impacts many vital organs and muscles.
Dr. Cahill authored more than 300
scientific articles and reviews in the field
of metabolism, many of them seminal
discoveries. The studies transformed sci-
entists’ understanding of starvation and
the way insulin regulates metabolism,
said Dr. Joseph Avruch, a professor of
medicine at the Harvard Medical School,
as referenced by the New York Times in
its August 17 tribute.
Former headmaster George Van
Santvoord described Dr. Cahill as “a vig-
orous young man of fine physique, good
intellectual ability, and excellent char-
acter.” Dr. Cahill’s legacy lives on in not
only his works, but also with generations
of researchers he impacted during his
teaching, administrative, and research
career at Harvard Medical school, Joslin
Diabetes Center, Howard Hughes Medical
Institute (HMMI), Dartmouth College, and
many more. Especially in Dartmouth, he
is remembered as a gifted teacher who
“could reduce the most complex bio-
chemical phenomena down to the under-
standing of a philosophy major,” wrote an
August 14 tribute from Dartmouth.
In 1990, Dr. Cahill was awarded
Alumnus of the Year at Hotchkiss to
celebrate his illustrious career. In this
issue No Limits commemorates him as a
distinguished alumnus. □Special thanks to the alumni office for pro-
viding us with with invaluable information.

ccording to a new study
led by University of Wis-
consin-Madison Research-
ers, the images of the
brains of those who are
diagnosed as psychopaths and those who
aren’t show significant differences. The
study discovered reduced
connectivity between an
area of prefrontal cortex
(PFC) and the amygdala.
The study took place in
a medium-security prison
in Wisconsin. Dr. Kent
Kiehl from the University
of New Mexico and the
MIND Research Network
brought a mobile MRI
scanner to the prison
and scanned the prison-
ers’ brains. Then another
investigator, Dr. Mike
Koenigs and his graduate
student, Julian Motzkin,
analyzed the brain scans.
The analysis com-
pared the brains of 20
prisoners with a diagno-
sis of psychopathy with
the brains of 20 other
prisoners who commit-
ted similar crimes but
were not diagnosed with psychopathy.
UW-Madison psychology Professor
Joseph Newman claimed, “The combina-
tion of structural and functional abnor-
malities provides compelling evidence
that the dysfunction observed in this
crucial social-emotional circuitry is a
stable characteristic of our psychopathic
offenders. I am optimistic that our ongo-
ing collaborative work will shed more
light on the source of this dysfunction
and strategies for treating the problem.”
The results could explain the heart-
less and impulsive antisocial behavior
of most psychopaths. The study showed
that psychopaths have reduced con-
nections between the ventromedial
prefrontal cortex (vmPFC), the part of
brain that controls the sentiments of
empathy and guilt, and the amygdala,
which is responsible for fear and anxiety.
Assistant professor of psychiatry in
the University of Wisconsin School of
Medicine and Public Health asserted,
“This is the first study to show both struc-
tural and functional differences in the
brains of people diagnosed with psy-
chopathy. Those two structures in the
brain, which are believed to regulate
emotion and social behavior, seem to
not be communicating as they should.”
The University of Haifa conducted a
similar study on psychopath brain struc-
ture. “Our findings show that people who
have psychopathic symp-
toms behave as though
they are suffering frontal
brain damage,” said Dr.
Simone Shamay-Tsoory,
who conducted the
study. The study assessed
17 people who are diag-
nosed as psychopathic,
but not suffering from
any brain damage; and
another 25 individu-
als who are experienc-
ing frontal lobe injury.
Each of the subjects
underwent a computer-
ized test examining the
ability to understand
another’s thoughts and
emotions and show em-
pathy for another’s emo-
tions. The results showed
that both psychopaths
with no brain damage
and individuals with
frontal lobe damage demonstrated a sim-
ilar difficulty of showing empathy. “Seeing
as psychopathic behavior is similar to that
of a person with brain damage, it could be
that it could benefit from similar forms of
treatment,” Dr. Shamay-Tsoory noted. □

hen one thinks of the
word “hypnosis,” im-
ages of polished pen-
dulums, mesmerizing
chants, or even The Professor from Gil-
ligan’s Island come to mind. For centu-
ries, hypnotism has always garnered the
attention of many, ranging from the de-
voted occult to the hopeful practitioner.
Hypnotism began with the work of Franz
Anton Mesmer in the 18th century. A sim-
ple Austrian physician, Mesmer believed
that he had discovered a phenomenon he
dubbed Animal Magnetism. He believed
that he could summon a healing wave of
bodily fluid controlled by the cosmos, and
that Animal Magnetism, which accumulat-
ed in his own body, could be passed on to
others. Mesmer therefore thought he had
the power to cure people in a hypnotic
ritual that became known as mesmerism.
In the early 19th century, James Braid,
a Scottish surgeon, developed hypnosis
which was based on Mesmer’s primi-
tive work. By investigating and later
developing his own trance-inducing
techniques, Braid created a crude form
of hypnotism to be used as a rudimen-
tary form of anesthetic during surgeries.
But what role does hypnosis play in
the world of modern medicine? To many,
it appears only as a quasi-science or fancy
magic trick. Despite this, the art of hyp-
nosis has actually been proven benefi-
cial to patients undergoing post-surgery
rest and recovery. A study by radiologists
at Harvard Medical School, published in
2000, found that patients who received
hypnosis before and after surgery re-
quired less medication, had fewer com-
plications, and underwent drastically
shorter recovery procedures than patients
who did not undergo hypnosis. In a 2002
follow-up study, the radiologists con-
cluded that if every patient having sur-
gery were to receive hypnosis the sav-
ings would amount to $338 per patient.
However, one must take caution in
agreeing to such a risky treatment. There
is no universal licensing process for hyp-
nosis practitioners. Edward Frischholz, a
clinical psychologist in Chicago who has
written more than 50 papers on clini-
cal and experimental hypnosis, said that
“hypnosis is like a surgeon’s knife: in the
right hands it can be life-saving, but in the
wrong it could cause harm.” (Lesley B6) □

SCHWANN CELL MIGRATION
BY DANIEL LEE ‘12
ver the summer of 2011,
I worked in a biomedical
engineering lab at Rensse-
laer Polytechnic Institute
that researches nerve re-
generation. The goal of my project was
to investigate the migration of Schwann
cells following electrical stimulation in
a 3D, carbon nanotube-embedded con-
struct.
The peripheral nervous system (PNS)
is made up of all nerves outside the brain
and the spinal cord, and it serves to con-
nect the central nervous system to limbs
and organs. In the event of a peripheral
nerve injury, due to a car accident, for ex-
ample, the severed nerve can only regen-
erate under optimal circumstances. Nerve
regeneration is impeded by factors such
as cell scarring, apoptosis (programmed
cell death), and a lack of a permissive en-
vironment. The role of Schwann cells is
critical in creating this permissive envi-
ronment for axonal regrowth.
Schwann cells are the support cells
of the PNS. They promote nerve regen-
eration by clearing scar tissue, releasing
soluble factors and expressing surface li-
gands, and thus allowing for the severed
nerve to reconnect. Thus, the migration of
Schwann cells to the injury site may be
critical in aiding nerve regeneration. Pre-
vious studies in the lab has shown that
in a 3D construct, electrically stimulated
Schwann cells migrate 68% further than
unstimulated cells.
However, applications of electrical
stimulation in the human body pose chal-
lenges because electrical signals may get
trapped in the adjacent connective tissue
before reaching the target site. Thus, an
inclusion of an electrically conductive
biomaterial may effectively focus the
electrical cues to the injury site, allowing
for a more effective treatment.
My hypothesis was that the addition of
single walled carbon nanotubes (SWCNT)
in conjunction with electrical stimulation
will cause the Schwann cells to migrate
further than samples without SWCNT. In
my experiment I embedded rat Schwann
cells in a hydrogel construct with SWCNT
and stimulated these constructs for eight
hours under 50mV/mm. Then, I stained
these constructs, imaged them using a
light microscope, and measured the dis-
tance migrated using the images.
I showed that the Schwann cells with
both electrical stimulation and electri-
cally conductive nanotubes displayed
further migration compared to cells with
either one cue or none.This study is a
first step in examining the feasibility of
using electrically conductive biomate-
rial for nerve injury. Future work includes
increasing the sample size, studying the
differences in the physical properties of
the SWCNT-laden hydrogel due to the
inclusion of the nanomaterial, enhancing
the dispersion of the nanomaterial within
the construct, and evaluating migration
over a wider range of electrical stimuli. □

Elephant researchers have found that the way these animals interact with their environment and each other could be proof of intelligence.”

No Limits • Fall 2012 • 13
ost people would include
humans, apes, and dol-
phins on the list of most
intelligent animals. How-
ever, a much larger mammal belongs on
this list as well: elephants. Through nu-
merous studies, scientists have collected
both physical and behavioral evidence
for their intelligence.
Elephant researchers have found that
the way these animals interact with their
environment and each other could be
proof of intelligence. One of the main
reasons is that, like primates, elephants
use tools. They grip sticks, stones, and
other objects with their trunks to intimi-
date enemies, scratch themselves, and
shoo away insects. Also, elephant calves
will play with found objects from their
environment.
Another reason scientists believe in
elephant intelligence is that they mourn
their dead. When a member of their herd
dies, elephants will gather around the
dead. They will watch over the body for
days, only leaving for food. Elephants are
migratory animals, traveling hundreds of
miles a year, but when they pass a spot
where a family member has died in the
past, they will pause and exhibit signs of
mourning.
Besides personal memory, elephants
appear to retain cultural memory as well.
This taught culture is one of the biggest
supporters of elephant intelligence. In
herds that have been hunted in the past
display an intense fear of humans. How-
ever, herds that haven’t been hunted re-
spond to humans in curious and friendly
manner.
One way scientists gauge animal in-
telligence is through the complexity of
their communication. Elephants interact
with each other both through body lan-
guage and verbally. However, their range
of hearing goes to a much lower decibel
than humans. Because of this ability, el-
ephants can communicate at the lower
frequency and make seismic “noises” that
travel as vibrations in the ground.
Lastly, the strongest case for elephant
intelligence is that they are self-aware.
They are capable of recognizing them-
selves in mirrors. If an elephant sees dirt
on itself in the mirror, it will try to rub the
smudge off.
Besides behavioral evidence, scientists
have found physical proof of intelligence
as well. Like a human, the elephant’s
brain develops over many years giving
the elephant a span of 10 years to ac-
quire knowledge. This ability to learn is
quite unique in the animal kingdom. Re-
searchers have also found that elephants
depend on these learned behaviors rath-
er than instinctual ones.
More physical evidence towards el-
ephantine intelligence is that the brain of
an elephant is highly convoluted. This in-
tricate folding increases the surface area
of the brain, as it does in other intelligent
species such as humans and dolphins.
Scientists believe that there is a direct
correlation between the amount of brain
folding and the intelligence of the mam-
mal.
However, because elephants are dif-
ferent species than humans, we must
be careful not to give their actions and
intelligence our motives. Their need to
communicate or use tools, while funda-
mentally similar, is very different from our
own need. The possibility of understand-
ing this unique intelligence would be lost
if we tried to inflict it with our own expe-
rience. □
ELEPHANTINTELLIGENCE
M

hroughout the history of man, one thing has been
passed on through generation after generation: cul-
ture. Similar to a gene, ideas that follow this type of
cultural transmission, coined “memes” are similar to
genetic transmission in that they both survive multiple genera-
tions, so to speak.
Coined by Richard Dawkins, the author of his 1976 book The
Selfish Gene, meme comes from the Greek root Mimeme, which
basically means imitation. In essence, a meme is an idea, behav-
ior, or concept that spreads from person to person within a cul-
ture.
Unlike genes, which modify the phenotype of an organism
and are passed on physically via DNA, memes often concern a
person’s mind, and are passed from person to person through
speech or other extracellular methods. Such examples of this
type of spread include tunes, ideas, fashions, and even the idea of
God, all of which originated from an individual or group of indi-
viduals, and propagated throughout the course of history. What is
interesting to discuss here, is the spread of such ideas and their
further effects on society.
Simply put, a meme “propagates [itself] in the meme pool
by leaping from brain to brain via a process which, in the broad
sense, can be called imitation,” (192). If a person hears, reads
about, or sees a good idea, he or she will pass it on to his friends,
and this process continues, until eventually, a large group of peo-
ple learns about it and it becomes a meme. The brain basically
becomes a vector in which the meme is allowed to propagate,
much like a virus takes over bacteria with its own phage DNA,
and propagates further using the cells as vectors.
In a more specific example, let us discuss the idea of God. In
and of itself, it is a very, very old concept. Yet, this concept has
been able to withstand countless generations and now exists in
various forms. But how has it been able to be passed on through
so many people while other ideas have failed to withstand the
test of such a transfer from one generation to another?
The question now becomes, “what is it about the idea of god
[or any meme] that gives it its stability and penetrance in the
cultural environment?” (193). As Dawkins puts it, “The survival
value of the god meme in the meme pool results from its great
psychological appeal. It provides a superficially plausible answer
to deep and troubling questions about existence,” (193).
MEMETHEORY

“What is it about the idea of god [or any meme] that gives it its stability and penetrance in the cultural environment?”
Most of what is unusual about man can be summed up in one word: ‘culture.’ ”
- Richard Dawkins, The Selfish Gene (p.89)
No Limits • Fall 2012 • 15
Similarly, a cultural meme such as jeans has spread because
the masses have found them comfortable and convenient. Thus,
memes are spread when people find them appealing and then
they are shared with others. Alternately, not all ideas will be able
to replicate. Such concepts are not popular in public opinion, and
after all: “[a meme’s] spread will depend on how acceptable it is
to the population, “(194). This type of weeding out of the bad
memes is analogous to natural selection of genes: the bad ones
simply do not propagate forward. Thus, memes really are “analo-
gous to genetic transmission in that… it can give rise to a form of
evolution,” (189), albeit a slightly different form than the form of
natural selection that is the characteristic of gene evolution.
There are also some memes that achieve short-term success in
propagating themselves rapidly, but do not last for much time in
the meme pool. Popular music is an example, satiating people’s
tastes until the next great hit comes out. Then, the older song is
simply forgotten. It is ideas that have meme potential that influ-
ence our society as a whole and the future of our society.
Going back to the meme of religion- the idea of God has
played a crucial role in societal development throughout history.
Early colonial America was purely based off of this meme. Nowa-
days, Internet memes and societal memes help to define our so-
ciety, its rules and ideologies, and each person as an individual.
Inventions are probably one of the most important memes of
our society today. Inventions such as the light bulb and cars have
lasted generations, giving proof to the survivability of memes.
Memes function very similarly to genes, in that they both
provide a ways for things to replicate themselves. Memes are
special because they require absolutely no tangible vectors in
order to replicate. The only vectors that are required by memes
are people’s minds. When you consider what you do in everyday
life, it will almost always relate back to one or more meme. □

How Did Life Begin?Scientists believe the first molecule to self-
replicate was similar to RNA, beginning the
process of evolution. Researchers at Georgia
Institute of Technology having been working
for more than a decade to understand how non-living molecules
combined to form the very first life. They have discovered that
small molecules may have acted as “molecular midwives” by as-
sisting the building blocks of genetic material in forming the
first short polymers of nucleic acids and by originally matching
the base pairs of the DNA double helix.
How Do Molecules Form?Scientists continue to disagree on what the
most accurate representation of a molecule
is since they are basing models on assump-
tions and approximate data. An electron
cloud with opposing electrostatic forces surrounds the atom’s
nucleus and the electrons are constantly moving. Computers
simulations can now calculate, with accuracy, the properties and
structures of molecules with relatively few electrons from quan-
tum first principles. The problem arises when the reaction’s elec-
tron count exceeds a few dozen, so modeling complex reactions,
like biomolecular processes, is still impossible.
How Does the Environment Influ-ence Our Genes?The control of gene activity seems to in-
volve chemical events happening at the
mesoscale, a scale greater than those of at-
oms and molecules. Chromatin, the mixture of proteins and DNA
that makes up chromosomes, has a structure greatly influenced
by the cell. The double helix of DNA is wound around histones,
which are bundled up into higher-order structures that are still
poorly understood. The way a gene is packed into this structure

determines whether or not it is active. Scientific understanding
of this process can help in the research and use of stem cells in
regenerative medicine and a greater understanding of genetic
diseases.
How Does the Brain Think and Form Memories?Although scientists have a basic under-
standing of the formation of habitual re-
flexes and everyday declarative memories
(people, places, etc.), there are still many gaps in brain sciences.
For example, we still do not understand how a memory is re-
called once it is stored. Learning about the chemistry of memory
making creates the controversial prospect of pharmacological
enhancement of memory.
How Many Elements Exist?The periodic table continues to grow as
scientists use particle accelerators to crash
atomic nuclei together to form new “su-
perheavy” elements. The nuclei are incred-
ibly instable and decay radioactively within a tiny fraction of a
second. The studies on these new elements test the conceptual
limits of the periodic table – do the superheavy elements still
display the trends in chemical behavior that originally shaped
the periodic table? Some do, but some don’t. Is there a limit to
the size of the superheavy elements? Simple calculations limit
the nuclei to 137 protons, but more sophisticated calculations
show it to be limitless.
Can Computers Be Made Out of Carbon?In 2010, the Nobel Prize in Physics was
awarded for the discovery of graphene, a
web of carbon atoms arranged in a chicken
wire-like pattern. Being an electrical conductor, hollow, extreme-
ly strong and stiff, graphene promised applications ranging from
high-strength carbon composites to tiny wires and electric de-
vices. The problem is finding the right techniques to use this new
molecule; the key might be precise atomic-scale engineering to
build the molecule from the bottom up with hexagonal carbon
rings.
How Do We Tap More Solar Ener-gy?We are expansively and inefficiently us-
ing solar energy since we are incapable of
harvesting vast amounts. The conventional
photovoltaic panels made of silicon are extremely expensive, re-
stricting their use. Biology shows us, however, that solar cells do
not have to be incredibly efficiently if they can be made cheaply
and abundantly. A group of scientists are creating an artificial
leaf that would produce fuel from solar energy by splitting water
into hydrogen and oxygen gas. The difficulty is finding a cheap
photocatalyst that does the splitting. Currently, a cobalt-based
catalyst is being used, but it is not ideal.
What is the Best Way to Make Bio-fuels?The creation of biofuels is, as of now, in-
credibly inefficient and impractical. To be
more feasible, mostly solid biofuels would
need to be converted into liquid fuels for easy transportation
along pipelines. This conversion would need to happen on site
(where the plants are harvested). There is, however, no general
consensus on the proper way to perform the creation of biofuels,
but the solution undoubtedly will be found with chemistry.
Can We Devise New Ways to Create Drugs?In the 1990s combinational chemistry was
the hope of creating new medicines by
randomly assembling molecules and then
testing to see which ones held potential – it produced virtu-
ally nothing useful. Due to modern developments, combi-chem
could make a return to biotechnological research. Scientists can
now refine the library of candidate molecules by using a kind of
Darwinian evolution is a test tube. Another possibility is protein
synthesis in cells to tailor new drugs.
Can We Continuously Monitor Our Own Chemistry?Biosensors that use chemical reactions
to monitor the concentration of glucose
date back to 1960s. But increasingly, sci-
entists want to create faster, cheaper, more sensitive and more
ubiquitous chemical sensing to aid in detecting food and water
contaminants, monitor pollutants in the air, and biomedical ap-
plications, such as chemical sensors that would recognize the
products of cancer genes circulating in the bloodstream long
before normal clinical tests could diagnose it. Chemists foresee
continuous, unobtrusive monitoring of all biochemical markers
of health and disease to provide real-time information to sur-
geons and to automated systems for delivering remedial drug
treatments. □

THE SCIENCEOF TYPOGRAPHY
ypography is the art and technique of
arranging ‘type’ – letters and characters – to
communicate an idea. Though not officially
a branch of science, typography is essential
to the study and creation of good design.
The term ‘typography’ isn’t commonly used in
everyday life, but the technique of typography is used
everywhere. Science textbooks, the headlines of The
Record, and even history papers, all involve typography.
Typography allows us to read things clearly, and good
typography can convey a message ‘in between the lines.’
All typefaces have their own personality and purpose.
Although a deep understanding of typography isn’t nec-
essary to score an A+ on an English essay, typography
can still be useful to enhance a piece of writing.
The Periodic Table of Typefaces
The Periodic Table of Typefaces was created by graphic
designer Cam Wilde. It is composed of 100 of the most
popular, influential, and notorious typefaces of today
and is organized into groups of typefaces: sans-serif,
serif, script, blackletter, glyphic, display, grotesque, real-
ist, didone, garalde, geometric, humanist, slab-serif, and
mixed. Each cell of the table contains the name of the
typeface, the symbol, the designer, and the year it was
designed. The typefaces are arranged in order of relative
rankings. Some typefaces were omitted to keep fami-
lies of typefaces together. To find out more about the
Periodic Table of Typefaces, visit http://www.behance.
net/gallery/Periodic-Table-of-Typefaces/193759.
Typography in Math and Science
Many science and math textbooks are often printed in
similar typefaces. This is because only a few typefaces
are compatible with mathematical symbols, Greek let-
ters, and other ‘special’ texts throughout math and sci-
ence; these publications typically use Computer Modern
or New Century Schoolbook. Such typefaces allow for

maximum clarity of numbers, letters, and symbols. TeX (pro-
nounced ‘teck’) is a text-formatting program used for typesetting
complex mathematical formulae and other technical material
attractively and consistently. It is commonly used in mathemat-
ics, computer science, economics, engineering, physics, statistics,
and quantitative psychology.
Typography for Essays
Teachers often set guidelines for font size, line spacing, margins,
and page limits for writing essays, and it can be a hassle to
edit an essay to meet the right requirements. Typography can
be helpful in these situations. If an essay is over the page limit,
Times New Roman will shrink it down. Or, if the essay is a little
too short, Verdana will stretch it out. The tracking of the text can
also be adjusted by right clicking and going to font > advanced
> spacing > condensed or expanded.
Typography in Graphic Design
Typography is used in many different areas of graphic design,
including posters, advertising and logo design. Type is combined
with negative space and graphic images to form relationships
between words and images. Graphic designers’ favorite type-
faces include Helvetica (e.g. the Microsoft logo), Futura (e.g. the
Adidas logo), Garamond (e.g. The Harry Potter books), Trajan (e.g.
the movie poster of Titanic), Myriad (e.g. Apple advertisements),
Franklin Gothic (e.g. the movie poster of The Dark Knight), and
Gill Sans (e.g. the London Underground logo). Popular typefaces
for display on screen include Lucida Grande, Verdana, and other
sans serif fonts. The graphic designers’ worst nightmare is the
abuse of Comic Sans MS. Some other misused and tacky type-
faces include Papyrus, Brush Script, Curlz MT, and Bradley Hand.
Economics of Typography
Ink is expensive. When it comes to printing large amounts of
text, the typeface that saves the most ink is Century Gothic,
which uses 30% less ink than Arial. However, Century Gothic
wastes more paper, so the best way to save money and the envi-
ronment is to avoid printing. Microsoft switched their default
typeface from Times New Roman to Calibri and Cambria because
of their higher readability on the screen. They believed that
the more pleasing that the text looks on the screen, the less
tempted someone will be to print out a document.
Terminology
When going into an in-depth study of typography, it is necessary
to know some key terms to identify different features of type-
faces. Here are a few basics to get started.
Font vs. Typeface: The most common misconception about
typography is the definition of the word ‘font’. Most people
would explain font as a style of letters, such as Times New
Roman, Georgia, or Comic sans. However, these names refer to a
specific typeface, while font refers to the collection of typeface,
size, weight or style.
Serif & Sans-serif: Serif refers to typefaces with a ‘decorative’
finishing stroke (called a Serif) at the end of character stems.
No Limits • Fall 2012 • 21
Sans Serif are typefaces with a lack of any Serifs.
Tracking and Kerning: Tracking is the adjustment of spacing
between characters of a whole group of characters (in a para-
graph or article), while kerning is the adjustment of spacing
between individual characters.
Leading: More commonly known as line spacing, leading is the
vertical line spacing between lines of text.
Weight: the thickness or width of strokes – light, medium, bold,
heavy, ultra, etc. □

article physics is vital to our understanding of
the world. It explains and explores the building
blocks of everything. This field of science gives us
insight to the origin and workings of the universe.
Despite particle physics’ important role in science,
however, it doesn’t attract much attention from the average per-
son, or the media. Recently, though, the Higgs Boson has gained
a great amount of publicity. Perhaps this is due to its sensational
title as “The God Particle”, or perhaps it is due to the creation of
CERN’s technologically advanced Large Hadron Collider (LHC) in
Geneva, Switzerland. The particle is known to be nature’s most
elusive particle, and most important subnuclear particle. In any
case, however, the Higgs should explain mass itself, and fill a
large gap in what we know about particle physics.
The Standard Model is a sort of chart that is used to explain
particle physics. Like the Periodic Table for chemistry, it provides
a foundation and structure for this field of study. Made up of
particles, the model is mainly divided into up, down, bottom, top,
strange, and charm quarks (some of which make up protons and
neutrons), and leptons (which include electrons). It is known,
however, that there are many particles missing, and spaces need-
ing to be filled, in this model.
The Higgs Boson is expected to fill a gap in our knowledge
of the major forces of the universe, which are gravity, the elec-
tromagnetic force, and the strong and weak radioactive forces.
In brief, it is believed that each of these forces has a respective
particle called a boson, through which the forces can be trans-
mitted, and affect matter. Despite finding the W and Z bosons
corresponding to the strong and weak radioactive forces, and
photons for the electromagnetic force, physicists were missing
the boson for the gravitational force. It is believed that the
Higgs will fill this role. (Atteberry).
Peter Higgs, a British physicist after whom the Higgs Boson’s
name originates, theorized about the particle in the 1960s. He
postulated that there was a Higgs Field, and proposed that in
this field, the Higgs boson transferred mass to a particle such as
a quark, electron, W, or Z particle. (“Origins CERN Ideas,”).
One analogy is often used to explain this field and how the
Higgs Boson gives particles mass. Imagine a fancy cocktail party

in a large room. Suddenly, a movie star enters the scene, and the
people nearest to the celebrity pack in around him, eager for
conversation. Particles such as the W and Z boson particles act
as these movie stars, and the flock of people around the celeb-
rity represent a particle’s mass. When the star passes through
the Higgs Field, they gain mass. The Higgs boson particle acts
as the eager party guest; it is a manifestation of the Higgs Field.
Some particles, however, such as photons, attract much less
attention at the party, and act as unimportant guests. When they
pass through the Higgs Field, they don’t create any ‘distortion’ in
the field, which renders them massless. (“Origins CERN Ideas,”).
The search for the Higgs has been going on for decades.
Physicists use particle accelerators to search for particles like
the Higgs Boson. Throughout the 1990s, CERN’s Large Electron-
Positron Collider (LEP) and Fermilab, near Batavia, Illinois, have
been the sites for countless tests and experiments to find this
particle (“Origins CERN Ideas,”). At LEP, it was thought that they
found traces of the Higgs Boson, but scientists weren’t sure
and the accelerator was shut down in 2000. In 2005, however,
CERN’s Large Hadron Collider, was completed, and is known to
be the world’s largest, and highest energy particle accelerator.
The LHC, like other particle accelerators, attempts to create
enough energy to form new particles, using strange ‘quantum
properties’. These massive underground rings fire bundles of
particles in opposite directions. When these bundles collide at
extremely high speeds, many of the particles are annihilated.
This annihilation releases energy, and strangely enough, this
energy simply converts to new particles that may be completely
unrelated to the particles annihilated. Some particles need
more energy than others to form, however, explaining the need
for larger and larger particle accelerators. The more energy you
have, the more particles you can create and discover (Anthony).
Even if a Higgs Boson is created in a test, however, it decom-
poses in a fraction of a second. Physivcists don’t have the
equipment to know that they’ve found it in that split second, so
they must look for what they believe the Higgs decomposes into.
Millions of measurements and tests must also be performed,
because sufficient is needed to show graphical evidence of the
Higgs Boson (it appears as a tiny bump on the graph). (Anthony).
Finally, on Wednesday, July 4, 2012, physicists from the LHC
announced that they had found evidence of a particle that had
the predicted mass of the Higgs Boson. With a one in a million
chance that they were wrong, they knew it had to be the God
Particle itself. The scientific community rejoiced, and physicists
likened the probable discovery to the unearthing of the DNA
sequence in the human body. (Perlman).
Despite the excitement many scientists felt at confirming the
Standard Model and our knowledge of Particle physics and the
universe, others were somewhat disappointed. As Ian Hinchliffe,
who leads a research team at the LHC, commented, “It would be
even more exciting [if it turned out not to be the Higgs Boson],
because then it would be something we hadn’t predicted at all,
and that’s what science is all about - finding your predictions are
wrong and starting all over again.” (Perlman).
Physicists are still working to completely confirm that this
particle is, in fact, the Higgs Boson, a process that will take
another few years. Unanswered questions remain. Why do some
particles gain plenty of mass in the Higgs field? And why do oth-
ers pass through the field without gaining any mass? (Anthony).
Nonetheless, we should greatly appreciate what was announced
on July 4th of this year. In the future, we’ll surely look back
on this event as a breakthrough in science and an important
moment in history. Who knows what this discovery could lead
to? □
1964Peter Higgs predicts the particle’s exis-tence.
1995The top quark is dis-covered by Fermilab in Batavia as pre-dicted by Higgs’s mechanism.
2001CERN rules out the existence of the Higgs with a mass below 115 gigaelec-tronvolts (GeV).

TIMELINE OF HIGGSScientists at CERN and Fermilab used acelerators to smash particles together at high speeds. This collision, if done at high speeds, results in the production of smaller particles, one of which could be the Higgs Boson. The fingerprint of this particle left behind after it decays can be measured in gigaelectronvolts and will also give an indication of the mass of the particle (as heavier particles would have a higher voltage). An upper limit means that the Higgs Boson’s fingerprint is below that specified voltage. A lower limit means that the fingerprint is above that specified voltage.

ating “space taxis.” The Mars exploration
program was one of the most affected
programs. NASA was in talks with the
European Space Agency (ESA) to invest
in a joint mission to Mars to bring back
soil samples. As a direct result of this
budget reduction, the initiative has been
postponed indefinitely. Consequently, the
Space Shuttle program was discontinued,
marking an enormous decrease in public
interest in space exploration and in NASA
overall. Sending humans into space is the
most exciting aspect of space travel, and
without it, the public’s ephemeral inter-
est is waning.
However, as Bolden said, NASA is not
giving up. NASA’s vision remains “to reach
for new heights and reveal the unknown
so that what we do and learn will benefit
all humankind.” (NASA mission statement)
NASA is also working in conjunction with
the Next Generation Air Transportation
System (NexGen) to discover more envi-
ronmentally friendly ways to build and
launch aircrafts. NASA is continuing to
be one of the global leaders in support
of advancing the International Space
Station. This space station relies on six
astronauts, all of whom are American,
who live in space for years at a time.
NASA has clearly not given up on the
ideas of humans in space, and even has
long-term goals of sending humans to
Mars and beyond.
Currently, NASA is supporting the
two Mars rovers, Cassini (orbits around
Saturn), Juno (on its way to Jupiter),
and many other probes. Beyond the
Solar System, the Hubble Telescope
was restored and is now being used to
observe the most distant parts of our
galaxy. Furthermore, NASA announced
the emergence of the new Space Launch
System, a uniquely American method
of launching rockets farther than ever
before. So maybe NASA isn’t in decline,
and this is merely the calm before the
resurgence of interest in space. A recent
article in Scientific American argued
that NASA’s space exploration program
is actually flourishing unbeknownst to
most of us, and its potential for an immi-
nent groundbreaking discovery is huge if
ample funding continuous.
Despite attempting to highlight its
human involvement, NASA, along with
many other space agencies, is work-
ing to make rockets solely operated by
machinery. While it is much safer and the
expected release date could be as soon
as 2017, the allure of sending a human
into space is lost. This creates a down-
ward spiral for NASA: less money creates
slower results in an increasingly impa-
tient nation. Clearly, investing in space is
not necessarily a top priority right now,
especially with our plunging economy
and high unemployment, but investing in
space can create jobs and spur interest.
This popularity can flourish, exposing
thousands of people to an exciting new
interest and a possible field of work.
As humans, we are inherently curious.
We are driven to answer unanswerable
questions: How did we get here? What
will happen to us? Are we alone in
this world? It is our natural instinct to
explore, and we must not ignore this. We
need to realize that these answers won’t
come easily, but we need to invest in
order to continue gathering the pieces of
an answer. □

ather than luring fish with
bait, a fly-fisherman uses arti-
ficial man-tied flies to trick
fish into biting it. He needs
to let his fly imitate not only the looks of
the favorite dish of the day, but also the
characteristic movement and behavior of
a real insect, whether it is a caddis fly or
mayfly nymph.
You may think it is easy because
fish may seem dimwitted, but that is
all relative. A novice fly-fisherman will
soon abandon his/her sense of human
superiority and learn to cherish patience,
humbleness on the river, along with pre-
cision and physics of fly fishing. On one
day, you may try ten different kinds of
flies—dry flies, streamers, and nymphs—
just to realize that trout jump in the air to
feed on everything but the flies you offer.
However, aside from reading tempera-
ture, current, location, and weather—as
much as they are important—the biggest
difference between a master fly-fisher-
man and a novice is the act of casting.
Casting is the core pride of fly fishing.
To catch a fish, a fisherman sends out a
fly attached to a 7-15 feet long leader,
a polyamide monofilament fishing line,
which is virtually invisible in water. The
leader, in turn, is attached to a thicker
and longer line, that is reeled in and
attached to the fishing rod. A common
misconception is that casting relies on
the fly; the truth is that you cast the line
while the fly just goes along for the ride.
When casting the rod, the line is lifted
and brought over your head behind you.
After letting the line “load” behind your
back while the rod stops in the air, the
rod is brought forth in front and the
line unrolls to gently place the fly on
water. The trick to casting is effectively
controlling many feet of leader and line
so that the fly lands in a desirable spot
of the river, causing gentle ripples, which

attract fish to bite. While practicing intri-
cate precise mechanics of casting, the
most common phrase a novice fisherman
will hear is “accelerate to a sudden stop.”
How does that relate to the explosive
power of casting? How does a graphite
or bamboo rod let 9 feet of line unroll
so straight?
Potential & Kinetic Energy
The key of the physics behind casting
is in the “stop” at “2 o’clock,” as Norman
McLean calls it. As the line comes to a
stop behind you before you swing for-
ward, potential energy is stored in the
rod. That energy is then transferred into
the line as it is cast forward in front.
Specifically, elastic potential energy is
what is stored in the elastic material of a
fly rod. A similar situation can be found
in a slingshot; if you stretch back the
band in a slingshot to propel a small rock
through the air, the slingshot will then
have potential energy. Once the band is
released, that potential energy becomes
kinetic energy or energy of motion, which
snaps the band and transfers energy to
the rock, which then flies through the
air. The same concept holds true for a
fishing rod. Because graphite or bamboo
rods are flexible, letting the weight of
the lines bend them as they are being
“loaded” behind your head stores energy
It is an art that is performed on a four-count rhythm between ten and two o’ clock.”

in the rod. This then provides the power
for a clean unrolling of lines.
Biomimicry
When the physics of casting is done, biol-
ogy plays another key role in the success
of casting. The flies are essentially a type
of biomimicry—man-tied flies attempt
to imitate the visuals and behavior of
common aquatic insects. Artificial flies
are tied with natural (eg. feathers) and
synthetic materials (eg. rubber, plastic,
and mylar) to represent a wide range
of insects. Different materials are put
together to configure certain weights
and behaviors of three big categories
of flies, depending on where they are
targeted. Dry flies float on the surface,
partially submerged emergers resemble
newly emerging insects, and nymphs,
streamers, and wet flies are purpose-
fully made heavier or less buoyant to
resemble insects in water. All of these
generally imitate natural insects, though
it is the fisherman’s ability to drift and
mend the lines well enough for the fly to
seem natural to a fish underwater; to be
effective at catching fish, the lines should
not disturb the natural drift of the fly on
the current. □
Fly fishing is part-physics, part-biology,
and of course, part-ecology. Mastering
mechanics of overhead casting and
understanding aquatic insects will
increase success of your fishing trips.
However, personal experience transcends
the science and adds the component
of art to this unique sport. Every time
I fish with the fly fishing crew in the
Housatonic River, I feel the force of load-
ing and unrolling in the handle of my rod,
see the line draw infinity signs as it sails
through the sky, and hear the fish flop-
ping on the surface or the trickling water.
Only experience will teach a novice how
to truly immerse in the river, and engage
in the art of “active meditation.”
This article is dedicated to Mr. Damon
White, who left school at the end of last
year. He introduced many students to fly-
fishing through literature.
