Here are a few fun videos. One is of the Northern Lights (Aurora Borealis) recently captured by an astronaut on the International Space Station. The other is of the Google-owned company Boston Dynamics’ robot called ATLAS (image). ATLAS is a two-legged humanoid robot. The video shows ATLAS running outdoors in the woods. The last video explains what a calorie means.
