Electrons DO NOT Spin
Quantum mechanics has a lot of weird stuff - but there’s thing that everyone agrees that no one understands. I’m talking about quantum spin. Let’s find out how chasing this elusive little behavior of the electron led us to some of the...

How An Extreme New Star Could Change All Cosmology
A new white dwarf has been discovered (poetically named: ZTF J1901+1458) that’s doing some stuff that no white dwarf should ever be able to do. In fact, it has multiple properties that are so extreme that it almost certainly did NOT form...

Will the Moon Ever Leave the Earth's Orbit?
Every year the moon’s orbit gets a little bigger and it moves just a little farther away. Should we worry about the Moon breaking free?

Why Do the Planets Orbit in the Same Plane?
While there is a little wiggle room, the planets in our solar system really are orbiting on mostly the same level. Why do they do that?

What Survives Inside A Black Hole?
Black holes are the result of absolute gravitational collapse of a massive body: a point of hypothetical infinite density surrounded by an event horizon. At that horizon time is frozen and the fabric of space itself cascades inwards at...

Feynman's Lost Lecture
This video recounts a lecture by Richard Feynman giving an elementary demonstration of why planets orbit in ellipses. See the excellent book by Judith and David Goodstein, "Feynman's lost lecture”, for the full story behind this lecture,...

Can A Starfox Barrel Roll Work In Space?
DO A BARREL ROLL! Or at least, try…? The iconic move from Star Fox seems so easy, just press a button and BOOM. The ship rolls. But HOW? Barrel rolls in atmosphere are easy to execute with the use of ailerons, but in space, it's a...

TED: The fascinating physics of everyday life | Helen Czerski
Physics doesn't just happen in a fancy lab -- it happens when you push a piece of buttered toast off the table or drop a couple of raisins in a fizzy drink or watch a coffee spill dry. Become a more interesting dinner guest as physicist...

Conservation of Angular Momentum
In this video Paul Andersen explains that the angular momentum of a system will be conserved as long as there is no net external torque. Both point objects and extended objects are covered along with several examples.

The Fastest Human-Made Object Ever
The record for the fastest thing ever created by humans is a tie between the Helios 2 probe and a manhole cover.

John Green: The nerd's guide to learning everything online
Some of us learn best in the classroom, and some of us ... well, we don't. But we still love to learn -- we just need to find the way that works for us. In this charming, personal talk, author John Green shares the community of learning...

Dark Matter is Slowing Down the Milky Way
The effects of dark matter on galaxies is a mystifying and difficult thing to study, but the Milky Way's galactic bar might present an exciting way to quantify how much of it exists!

Rotational Inertia
In this video Paul Andersen explains how the angular momentum of an object if a product of the rotational inertia and the angular velocity. The rotational inertia depends on the mass, radius and shape of the rotating objects. A sample...

TED-Ed: What on Earth is spin? - Brian Jones
Why does the Earth spin? Does a basketball falling from a spinning merry-go-round fall in a curve, as it appears to, or in a straight line? How can speed be manipulated while spinning? In short, why is the spinning motion so special?...

Quantum Physics in a Mirror Universe
When you look in mirror, and see what you think is a perfect reflection, you might be looking at universe whose laws are fundamentally different.

When Quasars When Quasars Collide STJC
In this video, we discuss the reports about the detection of a pair of supermassive black holes orbiting only one light year apart from each other. Studying the dance of these giants should tell us a ton about how black holes grow.

TED-Ed: The physics of the "hardest move" in ballet - Arleen Sugano
In the third act of "Swan Lake", the Black Swan pulls off a seemingly endless series of turns, bobbing up and down on one pointed foot and spinning around and around and around thirty-two times. How is this move - which is called a...

The Vector Properties of Angular Quantities
In this video Paul Andersen explains how a rotating system will have several quantities; including torque, angular velocity, angular acceleration and angular momentum. Each of these quantities have a vector property that can be...

Angular Momentum of a System
In this video Paul Andersen explains how the angular momentum of a system can be calculated by determining the angular momentum of all individual objects within the system. An inquiry activity using a gyroscope is also included.
