Five Of The Biggest, Baddest Supernova Varieties
Supernovae are only rare to the passive stargazer, but if you’re an astronomer studying them, you get to see some of the most brilliant explosions in the universe. Here are five of the most significant supernovae known to science.

Why Do You Remember The Past But Not The Future?
The laws of physics don’t specify an arrow of time - they don’t distinguish the past from the future. The equations we use to describe how things evolve forward in time also perfectly describe their evolution backwards in time. So the...

Systems and Objects
In this video Paul Andersen explains the differences between a system and an object. Depending on the scale it often times easies to view a system as an object if the constituent parts aren't relevant to the question being asked. He also...
