What is the difference between acids and bases? This is a commonly asked question in both chemistry and biology classes. In this video, we will go through the definition of acid and base, and why they are so important to us, and, uh,...

NASA's Lunar Reconnaissance Orbiter shows the Moon has some pretty unusual features!

Why Asperitas Clouds - or Undulatus Asperatus - are so rare.

A mutation is a random change in the DNA. Mutations can be neutral, which means it does not cause a change in a trait of the organism, or it could cause a beneficial or a harmful mutation. There are a few different types of mutations -...

Yes, it is theoretically possible to use telescopes to see if the moon landings were real, but practically no. It would take an incredibly powerful telescope to see signs of moon landings on the lunar surface, and even the best...

A circle is 360 degrees But have you ever thought why is a circle not a simpler number, like 10 degrees or 100 degrees? As it turns out 360 is actually a very good number. From a purely mathematical standpoint, a number like 10 or 100...
