There's No Such Thing As Cold
If cold isn't real, then how can I feel it?

Sometimes it's cold outside. But what if I told you that "cold" isn't real? There's no substance or quantity called "cold" in science. We can't measure the amount of "cold" in something. Instead it's about what's NOT there. In this week's video, learn the difference between heat and temperature, why a wind makes us feel colder, and what it's like to live as a mass of jiggling atoms. This is the physics of cold Cool PBS NOVA episode on the search for absolute zero: www.youtube.com/watch?v=y2jSv8PDDwA Richard Feynman on jiggling atoms: youtu.be/v3pYRn5j7oI The movement of atoms in a wind: www.newton.dep.anl.gov/askasci/chem03/chem03448.htm Why a breeze feels cool: physics.stackexchange.com/questions/72163/why-does-a-breeze-of-wind-make-us-feel-cooler Density of the interstellar medium: en.wikipedia.org/wiki/Interstellar_medium Have an idea for an episode or an amazing science question you want answered?

Energy 101: Geothermal Energy
See how we can generate clean, renewable energy from hot water sources deep beneath the Earth's surface. The video highlights the basic principles at work in geothermal energy production, and illustrates three different ways the Earth's heat can be converted into electricity.
