What triggers a chemical reaction? - Kareem Jarrah - YouTube

View full lesson: are in everything we see, and the reactions between them can look like anything from rust on a spoon to an explosion on your stovetop. But why do these reactions happen in the first place? Kareem Jarrah answers this question by examining the two underlying forces that drive both endothermic and exothermic chemical reactions: enthalpy and entropy.Lesson by Kareem Jarrah, animation by Flaming Medusa Studios Inc.

I'm sorry but why do they wait 7 years to build that wall? If anything it should have been built already because there has been way more storms that have hit the northeast coast that could have just as easily screwed them over even worse than Sandy. And yes, IDC if its only 5 miles long. As long as it protects people I'm happy for them.


maybe the 2nd one wasnt  supposed to be an Easter egg, it was an asset also used in Mirror's Edge. They both use Frosbite Engine and might have the same library of graphics. Maybe they have added that one just to put more detail on the map?


nothing about the "DJ Khaled" sign?
