Problem: Linus Carl Pauling (; February 28, 1901 - August 19, 1994) was an American chemist, biochemist, peace activist, author, educator, and husband of American human rights activist Ava Helen Pauling. He published more than 1,200 papers and books, of which about 850 dealt with scientific topics. New Scientist called him one of the 20 greatest scientists of all time, and as of 2000, he was rated the 16th most important scientist in history. Pauling was one of the founders of the fields of quantum chemistry and molecular biology.

In his first semester, Pauling registered for two courses in chemistry, two in mathematics, mechanical drawing, introduction to mining and use of explosives, modern English prose, gymnastics and military drill. He was active in campus life and founded the school's chapter of the Delta Upsilon fraternity. After his second year, he planned to take a job in Portland to help support his mother. The college offered him a position teaching quantitative analysis, a course he had just finished taking himself. He worked forty hours a week in the laboratory and classroom and earned $100 a month, enabling him to continue his studies.  In his last two years at school, Pauling became aware of the work of Gilbert N. Lewis and Irving Langmuir on the electronic structure of atoms and their bonding to form molecules. He decided to focus his research on how the physical and chemical properties of substances are related to the structure of the atoms of which they are composed, becoming one of the founders of the new science of quantum chemistry.  Engineering professor Samuel Graf selected Pauling to be his teaching assistant in a mechanics and materials course. During the winter of his senior year, Pauling taught a chemistry course for home economics majors. It was in one of these classes that Pauling met his future wife, Ava Helen Miller.  In 1922, Pauling graduated from Oregon State University (known then as Oregon Agricultural College) with a degree in chemical engineering. He went on to graduate school at the California Institute of Technology (Caltech) in Pasadena, California, under the guidance of Roscoe Dickinson and Richard Tolman. His graduate research involved the use of X-ray diffraction to determine the structure of crystals. He published seven papers on the crystal structure of minerals while he was at Caltech. He received his PhD in physical chemistry and mathematical physics, summa cum laude, in 1925.

What did Pauling major in at Oregon State University?

Background: Graeme Obree (born 11 September 1965), nicknamed The Flying Scotsman, is a Scottish racing cyclist who twice broke the world hour record, in July 1993 and April 1994, and was the individual pursuit world champion in 1993 and 1995. He was known for his unusual riding positions and for the Old Faithful bicycle he built which included parts from a washing machine. He joined a professional team in France but was fired before his first race. Obree has created some radical innovations in bicycle design and cycling position but has had problems with the cycling authorities banning the riding positions his designs required.
Context: Obree had built frames for his bike shop and made another for his record attempt. Instead of traditional dropped handlebars it had straight bars like those of a mountain bike. He placed them closer to the saddle than usual and rode with the bars under his chest, his elbows bent and tucked into his sides like those of a skier. Watching a washing machine spin at 1,200rpm led him to take the bearings, which he assumed must be of superior quality, and fit them to his bike. Obree later regretted admitting to the bearings experiment, because journalists referred to that before his achievements and other innovations.  Obree called his bike "Old Faithful". It has a narrow bottom bracket, around which the cranks revolve, to bring his legs closer together, as he thought this is the "natural" position. As shown in the film, he thought a tread of "one banana" would be ideal. The bike has no top tube, so that his knees did not hit the frame. The chainstays are not horizontal to the ground. Thus the cranks can pass with a narrow bottom bracket. The fork had only one blade, carefully shaped to be as narrow as possible. A French writer who tried it said the narrow handlebars made it hard to accelerate the machine in a straight line but, once it was at speed, he could hold the bars and get into Obree's tucked style.  At a high enough speed, [I could] tuck in my arms. And, above all, get in a very forward position on the bike, on the peak of the saddle. The Obree position isn't advantageous simply aerodynamically, it also allows, by pushing the point of pedalling towards the rear, to benefit from greater pressure while remaining in the saddle. You soon get an impression of speed, all the greater because you've got practically nothing [deux fois rien] between your hands. Two other things I noticed after a few hundred metres: I certainly didn't have the impression of turning 53 x 13, and the Obree position is no obstruction to breathing. But I wasn't pedalling at 55kmh, 100 turns of the pedals a minute, yet my arms already hurt.

Question:
Hedy Lamarr (; born Hedwig Eva Maria Kiesler, November 9, 1914 -  January 19, 2000) was an Austrian-born American film actress and inventor. At the beginning of World War II, Lamarr and composer George Antheil developed a radio guidance system for Allied torpedoes, which used spread spectrum and frequency hopping technology to defeat the threat of jamming by the Axis powers. Although the US Navy did not adopt the technology until the 1960s, the principles of their work are arguably incorporated into Bluetooth technology, and are similar to methods used in legacy versions of CDMA and Wi-Fi.
On August 10, 1933, Lamarr married Mandl, an Austrian military arms merchant and munitions manufacturer who was reputedly the third-richest man in Austria. She was 18 years old and he was 33. In her autobiography Ecstasy and Me, she described Mandl as an extremely controlling husband who strongly objected to her simulated orgasm scene in Ecstasy and prevented her from pursuing her acting career. She claimed she was kept a virtual prisoner in their castle home, Schloss Schwarzenau.  Mandl had close social and business ties to the fascist government of Italy, selling munitions to Mussolini, and although like Hedy, his own father was Jewish, had ties to the Nazi government of Germany, as well. Lamarr wrote that Mussolini and Hitler attended lavish parties at the Mandl home. Lamarr accompanied Mandl to business meetings, where he conferred with scientists and other professionals involved in military technology. These conferences were her introduction to the field of applied science and nurtured her latent talent in science.  Lamarr's marriage to Mandl eventually became unbearable, and she decided to separate herself from both him and her country. In her autobiography, she wrote that she disguised herself as her maid and fled to Paris, but by other accounts, she persuaded Mandl to let her wear all of her jewelry for a dinner party, then disappeared afterward. She writes about her marriage:  I knew very soon that I could never be an actress while I was his wife.... He was the absolute monarch in his marriage.... I was like a doll. I was like a thing, some object of art which had to be guarded--and imprisoned--having no mind, no life of its own.
