radiometer
A radiometer or roentgenometer is a device for measuring the radiant flux (power) of electromagnetic radiation. Generally, a radiometer is an infrared radiation detector or an ultraviolet detector.1 Microwave radiometers operate in the microwave wavelengths. While the term radiometer can refer to any device that measures electromagnetic radiation (e.g. light), the term is often used to refer specifically to a Crookes radiometer ("light-mill"), a device invented in 1873 in which a rotor (having vanes which are dark on one side, and light on the other) in a partial vacuum spins when exposed to light. A common belief (one originally held even by Crookes) is that the momentum of the absorbed light on the black faces makes the radiometer operate. If this were true, however, the radiometer would spin away from the non-black faces, since the photons bouncing off those faces impart more momentum than the photons absorbed on the black faces. Photons do exert radiation pressure on the faces, but those forces are dwarfed by other effects. The currently accepted explanation depends on having just the right degree of vacuum, and relates to the transfer of heat rather than the direct effect of photons. 23 A Nichols radiometer demonstrates photon pressure. It is much more sensitive than the Crookes radiometer and it operates in a complete vacuum, whereas operation of the Crookes radiometer requires an imperfect vacuum.
The Urban Dictionary Mug
I nutted in the mug. Loved it!!!!!!!!
I fucked this mug so hard, It became pregnant
Exactly as I ordered it. Shipping was perfect, got updates, accurate date of delivery, and no damage. This is a gift for my little brother.
i was put on a list for buying this mug. 10/10 would recommend
Great customer service and was a fun surprise for an inside joke to a coworker. 😊
Nice cup! Seems to be a quality piece.
This mug reminds me of when I was happy. When I was a wee little winker enjoying the wonders of this life!
The, "Wenomechainsama" Mug has amazing quality and an amazing definition! Can't belive my child's generation is so funny! Love - Sharen, 55, On facebook !<3
this mug reminds me of my cat, it does nothing and cant pour me a nice cup of joe. It is horrible, it doesn't tell nor does it allow me sip on it. It stops me from drinking from it, its like the mug is trying to torture me.
love this mug! Goes perfect with the Morbius meal.
Had no idea my name had a definition!!
Bought for an inside joke. Perfect.
i love the schizophrenia mug its amazing
This cute mug reminded me of a quote from an obscure biography I found quite by accident in a tiny hole-in-the-wall 2nd hand shop in Portland, ME in 1987: 'The Life and Times of Lazarus of Bethany'. Quote: " We are all walking wounded held together by the scars of our forbearance and the charity of our sisters and brothers." Truer words have never been said.
Love it . Its me down to a T
unlike most mug customization, you can say whatever the fuck you want. Bravo!
i liked that the mug had my name on it and a funny definition, i will definitely buy some for my friends(with their names of course).
I bought it as sort of a gag gift for my son and his new girlfriend and they loved it
I haven't even bought it, it smells nice
nice quality, vivid image
