Van Leeuwenhoek

In 1676 his credibility was questioned when he sent the Royal Society a copy of his first observations of microscopic single celled organisms. Heretofore, the existence of single celled organisms was entirely unknown … The Royal Society arranged to send an English vicar, as well as a team of respected jurists and doctors to Delft, Holland to determine whether it was in fact Van Leeuwenhoek's ability to observe and reason clearly (wikipedia)

La matèria cromosòmica és “un cristall aperiòdic”, constituït per la successió d'un nombre petit d'elements isomèrics*, la seqüència concreta dels quals és la responsable de la seva funcionalitat.

(*) “the number of atoms in such a structure need not to be very large to produce an almost unlimited number of possible arrangements. For illustration, think of the Morse code…”

Sequence alignment and comparison

substitution matrices

Sequence alignment The substitution matrices provided a model

under which the concept of optimal alignment could be formalized, and computed. The optimal alignment between two sequences is the alignment that maximizes the sum of the amino acid substitution values at each aligned position.

A R N D C Q A R N D C Q S K - E A E - S K E A E +1+3-1+3-2+2=6 -1+0+1+3-2+2=3

The total number of possible alignments between two sequences of length 100 is approximately 10200.

With DP the number of operations required to obtain the optimal alignment is aproximately 3x1002

1990:The human genome projectTHE HUMAN GENOME PROGRAM (HGP) is producing large quantities of complex map and DNA sequence data. Informatics projects in algorithms, software, and databases are crucial in accumulating and interpreting these data in a robust and automated fashion at genome and sequencing centers

Computer systems play essential roles in all aspects of genome research, from data acquisition and analysis to data management. Without powerful computers and appropriately designed data–management systems, high–volume genome research cannot proceed.

This proposal concerns the management of general information about accelerators and experiments at CERN. It discusses the problems of loss of information about complex evolving systems and derives a solution based on a distributed hypertext system (Tim Berners-Lee)
