Dolbear, a physics professor at Tufts College. Insects often use sound to communicate with each other. This affects how quickly these chemical muscle reactions can occur. Dolbear didn't identify what species of cricket his formula referenced, but many people think that offsite link he counted the chirps of the snowy tree cricket, which is now nicknamed the thermometer cricket, for its accuracy as a thermometer.
