William Osman (born June 8, 1991) is an American YouTuber and engineer based in Ventura, California.He makes videos about science and robots. He has gone viral for a 2017 video featuring a laser cut sculpture of Vin Diesel made of a ham and cheese sandwich and a 2021 video featuring a homemade X-ray machine.
A person can make a working speaker out of a paper plate, tin foil, a penny, and a minijack, for under a dollar. Busted Tory built the homemade speakers according to the Household Hacker's specifications and created his own surround sound setup, but when he turned on the music, the speakers did not work. When Kari suggested that there might not ...
The laser works by the same principle as the maser, but produces higher-frequency coherent radiation at visible wavelengths. The maser was the precursor to the laser, inspiring theoretical work by Townes and Arthur Leonard Schawlow that led to the invention of the laser in 1960 by Theodore Maiman. When the coherent optical oscillator was first ...
Chemical reaction in a burning jet of ethylene and nitrogen trifluoride (NF 3) Used in research for laser weaponry, operated in continuous-wave mode, can have power in the megawatt range. Deuterium fluoride laser ~3800 nm (3.6 to 4.2 μm) (~90% atm. transmittance) chemical reaction US military laser prototypes. COIL (chemical oxygen–iodine laser)
The current cost of suitable lasers is <100 $/Watt and the cost of suitable microwave sources is <$5/Watt. Mass production has lowered the production cost of microwave oven magnetrons to <0.01 $/Watt and some medical lasers to <10 $/Watt, though these are considered unsuitable for beam directors.

The result was the egg exploding in the face of one of his co-workers, who was looking in the kettle to observe. Spencer then created the first true microwave oven by attaching a high-density electromagnetic field generator to an enclosed metal box. The magnetron emitted microwaves into the metal box blocking any escape and allowing for ...
[43] The annual Theodore Maiman Student Paper Competition was established in 2008, endowed by major laser groups, and is administered by the OSA Foundation. [44] In 2010 numerous events were staged worldwide by major scientific and industry photonics organizations to celebrate the 50th anniversary of Maiman's first laser and subsequent lasers ...
