In later versions, the system could automatically direct aircraft to an interception by sending commands directly to the aircraft's autopilot. By the time it was fully operational the Soviet bomber threat had been replaced by the Soviet missile threat, for which SAGE was entirely inadequate. Nevertheless, SAGE was tremendously important; it led to huge advances in online systems and interactive computing, real-time computing, and data communications using modems. It is generally considered to be one of the most advanced and successful large computer systems ever developed. IBM's role in SAGE (the design and manufacture of the AN/FSQ-7 computer, a vacuum tube computer with ferrite core memory based on the never-built Whirlwind II) was an important factor leading to IBM's domination of the computer industry. Background Prior to the introduction of SAGE, the task of intercepting bombers was becoming increasingly difficult. This was the latest shift in a balance of power that had been see-sawing since the 1930s. During the leadup to World War II it was widely believed that the bomber was essentially immune, at least in any practical sense. As speeds approached 200 mph the time between seeing the bomber and it reaching its targets was growing so short that there was no time for interceptor aircraft to climb to altitude. Once the bombs were released the multi-engine bombers often had a performance advantage over the fighters, allowing them to escape with relative ease. The only apparent solution to this problem would be to keep fighters in the air on-station at all times, a practical impossibility due to the short flight times of contemporary fighters. Thousands of fighters would be needed to keep enough of them in the air at any one time to defend against a raid of perhaps a hundred bombers. Most believed "the bomber will always get through". The introduction of radar seriously upset this equation. Radar gave just enough warning time for fighters to "scramble" and be at the bomber's altitude by the time they arrived. In modern terms radar is a "force multiplier", allowing a small number of fighters to handle the task that would otherwise require many more aircraft. Speeds of the aircraft of the era were such that the rest of the task of intercepting the bombers could be carried out by hand. The RAF, for instance, used a large map with markers representing various radar contacts, with controllers relaying positions and directions to the aircraft by radio. In the post-war era, the speed of the new jet-powered aircraft increased by a factor of two to three, similarly decreasing the available effective response time. In a general sense this should not have cause a problem; although the bombers were approaching much faster and gave less warning time, the fighters intercepting them were also much faster and could climb to altitude in minutes. But it was all of the other tasks that caused the problem. This included collecting information about the targets from the radar sites, figuring out where they were going (developing a track), and then guiding the fighters to intercept them. A study in the 1950s by the RCAF concluded that it would take on the order of one minute per interception. With flight times on the order of an hour by several hundred aircraft, some were bound to escape interception due to operator overload. The balance shifted toward the attackers again. With nuclear bombs onboard, this was unacceptable. The problem became even more acute if the bombers attacked at low level. Radar is line-of-sight, so by approaching close to the ground they would remain hidden behind the curvature of the Earth until approaching to within a few tens of miles. With a jet bomber this meant the defenders had only a few minutes to react, far too little time to launch an interceptor, let alone guide it to an intercept. (Less)

Linus Pauling--How He Discovered the Alpha Helix

Linus Pauling, however, was not an early recipient. His work focused on the crystal structure of inorganic molecules, and he had shown little interest in biological substances. Nevertheless, impressed by the reputation Pauling was earning among chemists, Weaver visited Caltech and offered Pauling research support in hopes that he could shape the young chemist's research interests. Lured by Rockefeller money, Pauling in the early 1930s turned his attention to the structure of biomolecules, especially proteins such as hemoglobin and antibodies. Determining the structure of proteins at this time was an enormous problem. Most proteins were difficult to purify, easily degraded, and hard to characterize. Proteins appeared to be not only gigantic molecules comprising hundreds or thousands of atoms--structures much too large to determine directly with x-ray crystallography--but were also relatively fragile, losing their function (denaturing) after even slight heating or mechanical disturbance. No one at the time was even sure that they were distinct molecules--one popular theory held that proteins formed amorphous colloids, gels that did not lend themselves to molecular study. But once Weaver had convinced him to take on the challenge, Pauling succeeded by his hard work, his deep understanding of simpler chemical structures, and his model-building approach. To solve the problem of protein structure, Pauling first directed his laboratory coworkers to find the precise structures of several amino acids, the building blocks of proteins. This effort resulted in a far better understanding of these important components. Following on the ideas of the German biochemist, Emil Fischer, Pauling correctly theorized that amino acids linked to one another end-to-end, through relatively rigid bonds that would hold them in certain positions. From this initial understanding of amino acid bonds, he built up his ideas about larger-scale protein structures. Working with Alfred Mirsky in the mid-1930s, Pauling discovered that the denaturing of proteins was the result of breaking weak bonds, called hydrogen bonds, that pinned the amino acid chains into specific shapes and allowed them to function biochemically. Through the 1930s he used his lectures and persuasive writing to criticize rival theories of protein structure. In May 1951, he wrote a celebrated series of seven papers detailing the structures of a number of proteins at the level of individual atoms, including the structure of the single most important basic form of protein chain, the alpha helix (a hydrogen-bonded helical chain that is a structural component of most proteins). It was an astounding breakthrough, and it opened the door for an understanding of biology at the molecular level. Pauling's strategic approach to his research, as well as his specific discoveries, established him as a founding father of molecular biology. First, he worked to understand the structures of the subunits that make up the larger molecules. Then he determined how they could link together. He used the basic rules of chemistry and physics to limit and guide his hypotheses. Finally, he built models to test and elaborate his ideas. By using this approach, Pauling was able to make fundamental advances in determining the shapes of biomolecules, and this achievement then allowed him to investigate how chemical structure determines biological function. For Pauling, though, determining the structure of DNA was the prize that eluded him. In 1952, he proposed a three-chain helical structure for DNA. Hampered by inadequate data, he was mistaken. The following year, armed with better experimental results, James Watson and Francis Crick used Pauling's strategic approach and came up with the correct, double-helical structure. After years of hearing her husband answer questions about how he missed this essential discovery, Pauling's wife Ava Helen asked him--only half in jest--"If that was such an important problem, why didn't you work harder on it?" http://profiles.nlm.nih.gov/MM/Views/Exhibit/narrative/biomolecules.html (Less)
