Birth Of Galileo Galilei
Galileo Galilei was an astronomer and one of the most famous scientists of all time. Among he's discoveries and creations, Galileo invented the telescope, the military compass as well as identifying moons orbiting Jupiter and sunspots on the sun. -
Galileo's Thermometer/Thermoscope
In the year 1593, Galileo invented a basic water thermoscope in which for the first time allowed various temperatures to be measured. -
Santorio Santorio
Santorio Santorio was an Italian inventor who supported the evolution of the thermometer, but like Galileo, both theremometers weren't accurate. Santorio was the first to apply a number scale on his thermometer. -
Grand Duke Of Tuscany, Ferdinad II
Ferdinad the second was the next inventor to create the first enclosed "liquid-in-a-glass" thermometer. However, he had used alcohol as his liquid and was inaccurate as he used no scale. -
Daniel Gabriel Fahrenheit
Daniel Fahrenheit was a Polish-born dutch physicist who spent he's life studying and manufacturing scientific instruments. He was later well known as the first modern day thermometer inventor. -
Anders Celsius
Anders Celsius was a Swedish astronomer who created the Celsius temperature scale. He was a scholar in astronomy and built the first observatory in Sweden in 1741. -
The Modern Day Thermometer
The mercury thermometer (invented by Daniel Fahrenheit) was the first thermometer to accurately measure temperatures to a scale (Fahrenheit scale). Fahrenheit based his temperature scale on the temperature of the human body; on this scale, water freezes at 32 degrees and boils at 212 degrees. -
Celsius Temperature Scale
In the year 1742, Anders Celsius invented the Celsius temperature scale. This scale is also called the centigrade scale, centigrade meaning "consisting of or divided into 100 degrees". The freezing point on this scale is 0 degrees and the boiling point is 100 degrees. -
Birth Of Lord Kelvin
Lord Kelvin was a Scottish engineer, mathematician and physicist who dedicated he's life inventing and developing new and improved devices throughout the 1800's. -
The Kelvin Temperature Scale
The Kelvin temperature scale (or absolute scale), measures the limits and or extremes of hot & cold. This scale uses the same units as the Celsius scale but starts at "absolute zero", where everything including air freezes solid.
