The study of temperature, heat, and engines
A description of this strange form of matter, which only occurs at temperatures close to absolute zero.
Engineering for thermal expansion at nuclear waste sites
Nuclear waste can heat the rock mass in which it is stored. This can create problems unless the design accounts for possible thermal expansion.
Human body temperature
In healthy individuals, the body temperature varies between 36.5 and 37.5 degrees Celsius, measured orally. The peak is reached at 6:00 to 10:00 p.m. The lowest temperature occurs between 2:00 and 4:00 a.m.
Physicists chill matter close to absolute zero
In 2001, scientists at Georgia Tech used lasers to chill atoms and create a form of matter known as Bose-Einstein condensate.
The National Renewable Energy Lab provides information on the different ways that solar energy can be used, such as solar water heating, concentrating solar collectors, and photovoltaics.
