Inventors and Scientific Discoveries

Alfred Nobel invented dynamite in 1867. He used his wealth from this invention to establish the Nobel Prizes. Graham Bell invented the telephone, Franklin discovered electricity's nature, and Edison invented the light bulb and phonograph.

Benjamin Franklin invented bifocal lenses in the 1780s to correct both near and far vision. He was tired of constantly switching between two pairs of glasses. Alfred Nobel invented dynamite, Edison the light bulb, and Diesel the diesel engine.

Sir Frank Whittle invented the turbojet engine in the 1930s, patenting it in 1930. His work revolutionized aviation. Gottlieb Daimler worked on early automobiles, Roger Bacon was a medieval scholar, and Waterman invented the fountain pen.

Nicolaus Otto invented the four-stroke internal combustion engine (the Otto cycle) in 1876. Karl Benz built the first practical automobile using this engine. Roger Bacon was a medieval scholar, and Alan Turing was a computer scientist.

Lewis Waterman invented the practical fountain pen with a reliable feed system in 1884. Earlier versions existed but weren't reliable. John Loud invented the ballpoint pen, Frank Whittle the jet engine, and Macmillan added pedals to bicycles.

Benjamin Banneker (1731-1806) was a free African-American mathematician, astronomer, and inventor known for his almanacs and role in surveying the boundaries of Washington D.C. He is widely recognized as one of the first African-American inventors and scientists. George Washington Carver, Elijah McCoy, and Bessie Blount came later.

Igor Sikorsky (1889-1972) was a Russian-American aviation pioneer who designed and flew the world's first practical helicopter. While he worked on various aircraft including fixed-wing planes, his most significant contribution was the development of the helicopter in the 1940s.

Sir Frank Whittle (1907-1996) was a British RAF engineer who invented and patented the turbojet engine in 1930, leading to jet propulsion for aircraft. The jet engine revolutionized aviation by enabling much higher speeds and altitudes than piston engines. Radar was developed by Robert Watson-Watt, sonar is for underwater detection, and ethyl gasoline was developed by Thomas Midgley.

Thomas Jefferson (1743-1826), the third U.S. President, was a prolific inventor and polymath who invented the swivel chair, the spherical sundial, the moldboard plow (a better plow design), and the cipher wheel (for cryptography). George Washington, Alexander Hamilton, and John Adams were not known for such inventions.

Benjamin Franklin invented the glass armonica (or harmonica) in 1761, a musical instrument consisting of graduated glass bowls mounted on a horizontal spindle and played by touching them with wet fingers. The banjo has African origins, the oboe and clarinet were developed in Europe earlier. Franklin's instrument became popular in classical music for its ethereal tone.

Oppenheimer quoted this ancient Sanskrit verse from the Bhagavad Gita after witnessing the first atomic bomb test, reflecting his moral conflict about creating nuclear weapons. Homi Bhabha was India's nuclear pioneer, Werner von Braun developed rockets, and Anil Kakodkar was a later Indian nuclear scientist.

In the episode where the group discusses the 'Got Milk?' campaign, Ross characteristically claims that he invented the famous slogan. This is typical of Ross's tendency to make exaggerated claims about his intelligence and contributions, often for comedic effect. The actual 'Got Milk?' campaign was created by the advertising agency Goodby Silverstein & Partners in 1993.

Vinod Dahm was the lead architect of the Pentium chip at Intel. The other options are prominent Indian-origin executives in tech and banking, but not associated with the Pentium's development. Vinod Khosla co-founded Sun Microsystems, while Victor Menezes and Rana Talwar were banking executives.
