From the main image caption:
> SI temperature/coldness conversion scale: Temperatures on the Kelvin scale are shown in blue (Celsius scale in green, Fahrenheit scale in red), coldness values in gigabyte per nanojoule are shown in black
gigabyte per nanojoule? wat? I understand that this is some measure of entropy but the article never mentions bytes again which is slightly baffling.
- Smaug123 2y agoI am certainly no expert and couldn't have even begun to put an order of magnitude estimate on any of the quantities involved, but it sounded plausible. Source appears to be https://arxiv.org/abs/cond-mat/9711074 https://arxiv.org/abs/cond-mat/9711074 per https://en.wikipedia.org/wiki/Thermodynamic_beta#cite_note-cvinbits-6 https://en.wikipedia.org/wiki/Thermodynamic_beta#cite_note-c... .
- setopt 2y agoTemperature is indeed related to entropy and energy. Entropy is a measure of information, and at a microscopic level is defined similarly in physics and in information theory. (And can be converted from SI units to bits.)
