Can explosions work in space?
The most exciting SciFi movies have tons of space explosions. But how effective would explosions be in outer space with no atmosphere to carry the blast wave? Could a hypothetical explosion hurt you in space?

Grip - Science of Speed
There's one thing every driver always want more of: Grip. Grip is the frictional force that holds the tires on the track, but crew chiefs like Steve Letarte describe it as a 'warm and fuzzy feeling' when you have it. Whether mechanical...

Tires and Pressure - Science of Speed
NASCAR tires don't have "air pressure" because they're filled with nitrogen. The culprit responsible for increasing tire pressure during a race is friction. Using dry nitrogen gas helps the team predict how hot the tire will get and how...

Water and Diffusion - The Chemistry of Life
In this section, I talk about the properties of water, and what makes it unique. I talk about hydrogen bonds that result from the polar nature of water and why ice floats.
I also deal with diffusion and go into the 3 factors that affect...
