Nikolay Gennadiyevich Basov

Born 14 Dec 1922.Soviet physicist, best known for the development of the maser, the precursor of the laser. In 1955, while working as a research student with Aleksandr Prokhorov (1916- ) at the Soviet Academy of Sciences, he devised a microwave amplifier based on ammonia molecules. The two scientists shared the 1964 Nobel Prize (with American Charles Townes (1915- ), who independently developed a maser), for basic research in quantum electronics that led to the development of both the maser and the laser. These devices produce monochromatic, parallel, coherent beams of microwaves and light, respectively. Basov went on to develop the laser principle, and introduced the idea of using semiconductors to achieve laser action (1958). (a.k.a. Nikolai Gennadievich Basov)

Hannibal Buress: Cancer Walks

I don't believe in cancer walks. Well, I believe in them because they exist but I'd rather just give money straight up and save my Saturday afternoon. I can make my own t-shirt, that's not incentive. Plus I don't think cancer responds to how far people walk. I don't think cancer's sitting at home, 'What? How many people walked how far? How many people walked how far wearing the same shirt? That's crazy! I'm out of here!' Remission.
