Beskrivelse
Though people have surely commented on hot and cold weather for thousands of years, our most commonly used temperature scales both date from the eighteenth century. Daniel Gabriel Fahrenheit, who also played a key role in the development of the modern thermometer, invented the Fahrenheit scale. The Celsius scale is named after Anders Celsius, who not only developed it but also made important observations on the aurora borealis. Kids will learn about both scientists in this fascinating dual biography.
