7.A12 Freshman Seminar: Structural Basis of Genetic Material: Nucleic Acids (MIT)
Since the discovery of the structure of the DNA double helix in 1953 by Watson and Crick, the information on detailed molecular structures of DNA and RNA, namely, the foundation of genetic material, has expanded rapidly. This discovery is the beginning of the "Big Bang" of molecular biology and biotechnology. In this seminar, students discuss, from a historical perspective and current developments, the importance of pursuing the detailed structural basis of genetic materials.

Capturing design context in distributed communication of software engineers
Software engineering is a knowledge-intensive activity. It requires developers be aware of changing requirements, involvement of others, and the overall status of the project. Code, as the embodiment of developersâ intent, does not represent all knowledge required to work on the project successfully. Even in projects with the best software process practices, where requirement and design documents, bug databases, and source control software are kept up-to-date, most knowledge is still containe

EINSTEIN'S MESSENGERS, LIGO AND THE SEARCH FOR GRAVITY WAVES
By: nsf Einstein's Messengers is an Award-winning 20-minute documentary on LIGO, NSF's Laser Interferometer Gravitational Wave Observatory. The video examines how LIGO is spearheading the completely new field of gravitational wave astronomy and opening a whole new window on the universe. It explains how LIGO's exquisitely sensitive instruments may ultimately take us farther back in time than we've ever been, catching, perhaps, the first murmurs of the universe in formation. Above all, Einstein's

Transplant Cells, Not Organs
Pioneering surgeon Susan Lim performed the first liver transplant in Asia.

Evolving board evaluation fuctions for a complex strategy game
The development of board evaluation functions for complex strategy games has been approached in a variety of ways. The analysis of game interactions is recognized as a valid analogy to common real-world problems, which often present difficulty in designing algorithms to solve them. Genetic programming, as a branch of evolutionary computation,provides advantages over traditional algorithms in solving these complex real-world problems in speed, robustness and flexibility. This thesis attempts to a

Jeff Gold Inaugural Lecture - The Leader's Conundrum or 'You cannot lift yourself up by your own shi
The aim of the lecture will be to do demonstrate the need to challenge continuing traditional images of leaders, often depicted at the apex of things, on top of a hill or at the centre of a complex web of activity. I will argue that those nominated as leaders MUST become aware of what I will call the leader's conundrum and complement their inspiration with 99 x perspiration. To appreciate this call, attendees to the lecture as respectfully asked to do the following just before the lecture: a.

5.3 Back to the bicycle

Let's assume that our bicycle frame could still be constructed from ties and struts. If we want to select the material to minimise the weight of a frame for a particular frame strength, we need to devise a merit index as follows.

The mass of the tie-rods and struts needed for the frame is given by:
