Learning Philosophy

Format of class:• Active, participatory class.• Interaction with each other.• Images are as important as text.• I will ask questions and wait for an answer.

• Encourage thinking in class.• About 50% of material will be math.• Take notes – write down what I say.

– share note-taking– University Learning Centre has

workshops: http://umanitoba.ca/student/u1/lac/workshops/workshops.html

Materials:• Textbook is Astronomy Today, 6th edition Chaisson & McMillian and will be in the library. If bought new, there is a website with lots of multiple choice questions for practise. • The website for this course:

• iclicker• will register these in class on Monday.

• Non-programmable calculator, for tests and exams.

Guideline for grades:• C-C+ is roughly 60-69% average is about 65%• B-B+ is roughly 70-79% good to very good• A is roughly 80-89% excellent• A+ is > 90% EXCEPTIONAL

The factor that correlates most closely with grades is attendance at lectures.

4. Ways of Learning:– Quiz to determine whether you are

predominantly an haptic, auditory or visual learner is under the “learning styles” link at

http://www.physics.umanitoba.ca/~english/2010winterphys1810/

5. Pneumonics, meditation, etc.

3. Spend 3 hours studying for every hour in lecture. (Princeton Guidelines.)

6. Visit your professor. (Email or phone to make an appointment if you can’t visit Mondays at 1pm.

Scientific Method: Richard Feynman

• Observation, reason, and experiment make up what we call the scientific method.

• The principle of science, the definition, almost, is the following: The test of all knowledge is experiment. Experiment is the sole judge of scientific “truth.”

summary

Recall column

Scientific Method: Richard Feynman

• Where do the laws that are to be tested come from? Experiment, itself, helps to produce these laws, in the sense that it gives us hints. But also needed is imagination to create from these hints the great generalizations - to guess at the wonderful, simple, but very strange patterns beneath them all, and then to experiment to check again whether we have made the right guess.

summary

Recall column

Scientific Method: Gottfried Wilhelm Von Leibniz

• There are 2 kinds of truths; those of reasoning and those of fact.

• Truths of reasoning are necessary, and their opposite is impossible.

• And those of fact are contingent, and their opposite is possible.

Scientific Method

Science is a truth of a) reasoningb) fact

summary

Recall column

Scientific Method:

• “Laws of Nature” are defined as general rules that describe how nature works.

• Evolution from one law to another, not a revolution. E.g. Newton’s Law of Gravitation is contained in Einstein’s General Theory of Relativity.

Scientific Method

Discuss with your neighbours:Compare the scientific approach to

understanding the cosmos with other approaches such as theological, spiritual, and astrological efforts, in attempts to estimate the probability of sentient, technological life arising elsewhere in the universe. Do you feel that the scientific attitude is basically different than the others? Why?
