Mechanical Calculator, Piano, Thermometer, Seismometer

Gottfried Leibniz
The first day I studied Gottfried Leibniz. Gottfried Leibniz made the mechanical calculator better. He was born in 1646. His progress with the mechanical calculator kept the field alive.

Bart Cristofori invented the piano around 1700 in Italy. Bart Cristofori began selling his piano as Medici's Wealth declined. The piano led to the development of the electronic keyboard.

Daniel Fahrenheit was born in 1686 and lived in the Dutch Republic. Daniel Fahrenheit invented the mercury thermometer. Thermometers measure temperature. Early thermometers were developed by the 160s in Italy but didn't have standard scales.

The Chinese invented the seismometer in 132 A.D.Seisemometers measure earthquakes. Earthquakes were disastrous to the economy. Seismometers helped save lives by providing early warnings.
