galileo thermoscope — invented by galileo galilei around 1593, first device to measure temperature changes using air expansion in a tube
mercury thermometer — developed by daniel gabriel fahrenheit in 1714, became the standard for 200+ years using mercury's expansion to measure heat
digital thermometer — invented in the 1960s, uses thermistors and electronic displays, now the most common household thermometer worldwide
