The optical density of silicon naturally changes when it's exposed to even slight temperature shifts, making it a sensitive material especially suited
for thermometry, according to Han.
«We've been exploring the potential of defect spins
for thermometry for the past few years,» said David Toyli, a graduate student in physics at UCSB and lead author of the temperature sensing work.

Tripati and her team used a technique known as clumped isotope
thermometry, which examines the calcium carbonate shells of marine plankton
for subtle differences in the amounts of carbon - 13 and oxygen - 18 they contain.
Sure, given that nearly any introductory physics textbook — I'm not talking about thermodynamics text, just things like Tipler and Mosca, or Halliday, Resnick and Walker — teach enough thermodynamics
for one to be able to see that the spontaneous appearance of a stable thermal gradient in any system is impossible, because it is a direct violation of the second law, and indirectly the first, which more or less says that equilibrium is isothermal (in order to permit the definition of
thermometry in the first place).
