Our family had a great time with this Loki Lego Launcher project. Not only did our kids get a big sense of accomplishment by successfully sending a balloon to near space, but it was a ton of fun and we got some fantastic footage too.

Is time travel possible?

AdultsPhysicsScience
Time travel is a staple of science fiction stories, but is it actually possible? It turns out nature does allow a way of bending time, an exciting possibility suggested by Albert Einstein when he discovered special relativity over one hundred years ago. Colin Stuart imagines where (or, when) this fascinating phenomenon, time dilation, may one day take us.

How batteries work

AdultsHistoryPhysicsTechnology...
Batteries are a triumph of science-they allow smartphones and other technologies to exist without anchoring us to an infernal tangle of power cables. Yet even the best batteries will diminish daily, slowly losing capacity until they finally die. Why does this happen, and how do our batteries even store so much charge in the first place? Adam Jacobson gives the basics on batteries.

The beginning of the universe, for beginners

AdultsHistorySpacePhysics...
How did the universe begin -- and how is it expanding? CERN physicist Tom Whyntie shows how cosmologists and particle physicists explore these questions by replicating the heat, energy, and activity of the first few seconds of our universe, from right after the Big Bang.
