Most of today’s astronomy is based on the detection of electromagnetic radiation in various frequencies like radio waves, visible light and x-rays, and on the detection of cosmic neutrinos. But ,there is another way to perceive the Universe: as we know from Einstein’s General Theory of Relativity, massive objects can also emit gravitational waves. Measuring
How does Tony Stark aka Iron Man fly? I know there are rockets and thrusters involved, but that’s not quite what I mean. I mean how does Iron Man fly around without his body inside turning into jelly? Alright this is what I mean, take a look at this footage. How is Tony making what
Consider throwing a ball straight into the air. Can you predict the motion of the ball after it leaves your hand? Sure, that’s easy. The ball will move upward until it gets to some highest point, then it will come back down and land in your hand again. Of course, that’s what happens, and you
Hey it’s me Destin, welcome back to Smarter Every Day. So did you realize that Harry Houdini was the first person to fly an airplane in Australia? I didn’t either, that’s crazy.

Hey there BrainStuffers, Lauren here. If you like art, permanence, and shallow wounds, you may have a tattoo or seven. And you’re not alone: A Harris poll from 2012 indicates that here in the U.S., almost 40 percent in adults under the age of 40 have at least one. So our question for the day
(helicopter flying) (alarm systems beeping) – [Instructor] Ditching, ditching, ditching. (water rushing) – So, I’m alive. (laughs) All right, here’s the deal. My last mission as a U.S. government civil servant was in a helicopter off the coast of Hawaii. We’ll learn about that in a future episode, but this video’s different. This is not
Hey it’s me Destin Welcome back to Smarter Every Day. So in the last video we talked about what it was like to get a tattoo in slow motion. But this time we’re gonna talk about the removal process. It’s way more complicated. It involves physics like thermodynamics, optics, even biology and chemistry are involved.
