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.

A gift for my sis who got betrayed by her supposed to be friend. His loss for ever RIH stan
Speedy shipping and as always love the mug especially since I created the word!
My brother is a marathon runner, but he’s British. Instead of drinking water from a bottle like a sane person, he uses this to drink his black tea during runs. Now I can die in peace knowing he’s drinking from a mug with the definition of the word “objectumsexual” for some reason.
Bought this without checking the back for my 12 year old cousin's birthday who adores trains! He's a lil autistic. I thought to 'run a train' meant to work on it and keep it running, much like my cousin is always talking about how he wants to drive a train. I was distraught to hear him turn over the mug on his bday in front of his two very strict puritan parents. My auntie and uncle are threatening to put me on a list now and threatening to sue me for defamation or some shit idk i didnt go to law school cus im not a nerd lols. (unlike them who both went to university) i got a kick ass job as a bouncer for an under 18s club - youd be surprised how big 12 year olds get- but they are just stupid. im worried i might get fired if this leaks.) Thanks a bunch! (sarcasn) - im feeling p down atm, if anyone could cheer me up, my number is 0800 1111, if anyone wants to do whats on the mug LOL (serious). btw, i kept the mug for myself since i found it decently adequate and quite tasteful. /srs
Thanks guys, I knew I was hot but not *that* hot
Great way to wake up and clear your head every morning with the reminder of the day you woke up dumb enough to spend $32.95 for a basic coffee mug
Couldn't wait until the mug got home. Immediately after i bought it i wet myself. I couldn't help it. I got so bored of waiting i ordered 5 more mugs. And then another 5. And then ANOTHER 5. And now i have fucking 60 mugs that say schizophrenia on them. I only intended on gifting this mug to my schizophrenic younger sibling as a last gift before i inevitably must suffocate him with his own pillow. Now with all these mugs and have decided to put one mug on the old couple across the street's doorstep each day until eventually they are convinced that they are schizophrenic and see things that aren't there. Next i will get them to be taken to a mental institute where they will be locked up to live in an all-white facility for the rest of their lives. My hope is that i can do this to all of the neighbors on my street so i can finally get enough space so that i can run my hamster experiments in peace without my neighbors always wonder what the small hamster screams coming from my basement are. Anyways nice mug 8/10.
