TED-Ed: The tech that seems to break the laws of physics | Anna Rothschild
Typically, with any piece of technology, you pump one unit of energy in and you get about one out. That’s just the first law of thermodynamics: energy has to be conserved. But there’s a piece of technology called a heat pump, where for...

The Impossibility of Perpetual Motion Machines
Bad ideas come and go in physics. But there’s one bit of nonsense that is perhaps more persistent than all others: the perpetual motion machine. No working perpetual motion machine has ever been experiment verified. All break the laws of...

The Trebuchet Challenge | Space Time
Kinetic and potential energy are defined as combinations of more basic quantities: position, velocity and mass. These combinations are chosen so that their sum is conserved. It’s actually remarkable that there’s any such combination of...

There's a Loophole in One of the Most Important Laws of Physics
The laws of thermodynamics are cornerstones of physics - but one of them is more breakable than it appears. Hosted by: Olivia Gordon

Environmental Systems
In this video Paul Andersen explains how matter and energy are conserved within the Earth's system. Matter is a closed system and Energy is open to the surroundings. In natural systems steady state is maintained through feedback loops...

Bioenergetics
Paul Andersen introduces the concept of bioenergetics. He explains how living organisms utilize free energy in the Universe. He begins with a brief discussion of thermodynamics and Gibbs free energy. He then explains how reactions can be...

Reversing Entropy with Maxwell's Demon
The second law of thermodynamics - the law that entropy must, on average, increase - has been interpreted as the inevitability of the decay of structure. This is .... misleading. Structure can develop in one region even as the entropy of...

The Leidenfrost Effect: How to Make a Liquid Levitate
In this video Michael Aranda explains what the Leidenfrost Effect is, and how it can cause liquid to 'levitate'.

Mass-Producing Ice Cream with Food Engineering: Crash Course Engineering #39
In this episode, we looked at food engineering. We explored how food’s capacity to spoil makes it a unique challenge from an engineering viewpoint. We saw how many branches of engineering come into play to process ingredients, ensure...

Kinetic Reaction Control
In this video Paul Andersen explains how a spontaneous process may take either the thermodynamically controlled or the kinetic controlled pathway. If the activation energy determines the path taken then the process is under kinetic...

Q10 - The Temperature Coefficient
In this video Paul Andersen defines Q10 as the ratio between reactions at different temperatures. He then gives you an example of how it could be calculated. He also includes extensions of other scientific phenomenon that could created...

The Black Hole Entropy Enigma
Black Holes should have no entropy, but they in fact hold most of the entropy in the universe. Let's figure this out.

TED-Ed: Why don't perpetual motion machines ever work? - Netta Schramm
Perpetual motion machines - devices that can do work indefinitely without any external energy source - have captured many inventors' imaginations because they could totally transform our relationship with energy. There's just one...

How "Cold-Blooded" Animals Survive the Cold
We humans can rely on our internal body heat to help keep us warm. But what can cold-blooded animals do when faced with the threat of freezing? Here are three creatures that have come up with some...“cool” solutions.

Why Is the Freezer Harder to Open the Second Time?
There’s a moment after you close your freezer door that it becomes slightly harder to open again. It might pass quickly, but it’s not just in your head.

How Cells Hack Entropy to Live
One of the most fundamental ideas in physics is that the disorder of the universe, also known as entropy, is constantly increasing. But, life’s inherent chemical makeup has been hacking the disorder of the universe for billions of years!

Driving Nonspontaneous Processes
In this video Paul Andersen explains how you can drive non spontaneous processes by adding external energy (like electricity or light) or by coupling it to a spontaneous process (like the conversion of ATP to ADP)

Thermodynamics and Energy Diagrams - Crash Course Organic Chemistry
In organic chemistry, different reactions can take place at vastly different speeds. To better understand whether a reaction actually will happen, and how useful that reaction is, we need to understand thermodynamics and kinetics. In...

There's No Such Thing As Cold
You've felt cold before. Sometimes it's cold outside. But what if I told you that "cold" isn't real? There's no substance or quantity called "cold" in science. We can't measure the amount of "cold" in something. Instead it's about what's...

The Physics of Life (ft. It's Okay to be Smart & PBS Eons!)
Our universe is prone to increasing disorder and chaos. So how did it generate the extreme complexity we see in life? Actually, the laws of physics themselves may demand it.

Second Law of Thermodynamics
In this video Paul Andersen explains how the second law of thermodynamics applies to reversible and irreversible processes. In a reversible process the net change in entropy is zero. In and irreversible process the entropy will always...

Gibbs Free Energy
Paul Andersen attempts to explain Gibbs Free Energy. He begins by using three spontaneous reactions to explain how a change in enthalpy, entropy and temperature can affect the free energy of a system. He then applies this concept to...
