Why Are Airplane Engines So Big?
The answer to this question has everything to do with drag & kinetic energy vs momentum change (thrust) ie, a bigger engine fan allows for a larger air mass to be accelerated a smaller amount to give the same thrust as you'd get from a...

The Surprisingly Useful Physics of Desk Toys
How do Newton's Cradles connect to cancer treatments? Let's unpack the physics of some of our favorite desk toys, from dippy birds to perpetual motion machines, and explore how these scientific principles can be used beyond an office desk.

Is Interstellar Travel Impossible?
Space is pretty deadly. But is it so deadly that we’re effectively imprisoned in our solar system forever? Many have said so, but a few have actually figured it out.

How Black Holes Spin Space Time
If there’s one thing cooler than a black hole it’s a rotating black hole. Why? Because we can use them as futuristic power generators, galactic-scale bombs, and portals to other universes. Black holes are self-sustaining holes in the...

The Arrow of Time and How to Reverse It
Ever wish you could travel backward in time and do things differently? Good news: the laws of physics seem to say traveling backward in time is the same as traveling forwards. So why do we seem to be stuck in this inexorable flow towards...

What If Dark Energy is a New Quantum Field?
What is Quintessence? Well we know that something is up with the way the universe is expanding - there’s some kind of anti-gravitational effect that’s causing the expansion to accelerate. We don’t know what it is - just that it competes...

The Equation That Explains (Nearly) Everything!
The Standard Model of particle physics is arguably the most successful theory in the history of physics. It predicts the results of experiments with a numerical precision unmatched by any other branch of science, and it does so almost...

Is ACTION The Most Fundamental Property in Physics?
It’s about time we discussed an obscure concept in physics that may be more fundamental than energy and entropy and perhaps time itself. That’s right - the time has come for Action.

Will the Universe Expand Forever?
Throughout history, there has been much speculation about what the fate of the universe would be. Many theorized that the universe would eventually succumb to the pull of gravity, and reverse its expansion in what was being called ‘The...

The Future of Gravitational Waves
On September 14th, 2015 LIGO announced the first detection of a gravitational wave. This was hailed at the time as the dawn of gravitational wave astronomy. However that’s only true if the we ever detect another gravitational wave. Now...

The Physics of Windmill Design
This video is about how physics dictates the design of modern windmills - why they are so big, have so few blades, and have such skinny blades.

Most Collisions Are Secretly in One Dimension
This video is about elastic and inelastic collisions in 1D, 2D and 3D - and how the collision of conservation of energy with conservation of momentum, plus a secret direction, results in a completely predetermined behavior for most...

TED-Ed: Could we harness the power of a black hole? | Fabio Pacucci
Imagine a distant future when humans reach beyond Earth, forge cities on planets thousands of light-years away, and maintain a galactic web of trade and transport. What would it take to make that leap? And where would we get enough...
