The AH-64 Apache attack helicopter is the most advanced military helicopter in the world! Well, probably...Rumor has it, after the Vietnam war, the importance of helicopters was made clear, but the old Cheyanne was too slow on the attack and not well equipped for countering the heavily armored tanks of the USSR. After a quick contest to see who cou…
 
There are tons of new inventions showing up every day, but what about those inventions from years ago that got us to where we are today?

In our third episode about the Periodic Table of Elements, we learned that not all elements are created equal. Sure, we knew that, but we didn't know how useless some elements out there really are (we're talking to you Einsteinium and Mendelevium). That doesn't mean that the history of how they were discovered isn't interesting!Thankfully, we also …
