Length Contraction and Time Dilation | Special Relativity Ch. 5

Go to http://brilliant.org/MinutePhysics for 20% off a premium subscription to Brilliant! Mark Rober's youtube channel: https://www.youtube.com/markrober This video is chapter 5 in my series on special relativity, and it covers how things that are moving (that is, moving relative to an inertial reference frame) at different speeds appear to be shorter in length... and longer in length. And shorter in time, and longer in time. It all makes se...

The Brown Dwarf Debate

Thanks to NASA's James Webb Space Telescope (JWST) project and the Space Telescope Science Institute for supporting this video. This video is about the line between Brown dwarfs and gas giant planets (aka super Jupiter's): does it exist? Is it the deuterium-burning threshold? Behavior? Metallicity? Formation? Or is there no meaningful scientific distinction, and are brown dwarfs and giant planets really all on a spectrum with no clear line be...

NEW SHOW! | The Science of Seeing

Watch Paradigms Here: http://vrv.co/paradigms And please let me know what you think! Paradigms is a pilot for a new show about how we know what we know, produced in collaboration with MinuteEarth (http://youtube.com/minuteearth), Veritasium (http://youtube.com/veritasium), and Aatish Bhatia. The first episode is about the science of seeing, from the extramission theories of the ancient Greeks (like Plato and Euclid and Galen) to the Islamic s...

Spacetime Diagrams | Special Relativity Ch. 2

Go to http://brilliant.org/MinutePhysicsSpecialRelativity to learn more about spacetime diagrams and for 20% off a premium subscription to Brilliant. This video is chapter 2 in my series on special relativity, and it covers spacetime diagrams, rotational and translational symmetry of both time and space, how certain transformations preserve distances (measured in terms of a reference like a meter or second), and so on. We'll wait until the ne...
