TED-ED: What triggers a chemical reaction? - Kareem Jarrah

Pre-K - Higher Ed
Chemicals are in everything we see, and the reactions between them can look like anything from rust on a spoon to an explosion on your stovetop. But why do these reactions happen in the first place? Kareem Jarrah answers this question by...

Spontaneous Processes

12th - Higher Ed
In this video Paul Andersen discriminates between spontaneous (or thermodynamically favored) processes and those that are not spontaneous. A spontaneous process requires no external energy source. If the enthalpy change in a reaction is...

Gibbs Free Energy

12th - Higher Ed
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...

The Impossibility of Perpetual Motion Machines

12th - Higher Ed
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...

Boltzmann Brain Paradox Explained in Simple Words

Pre-K - Higher Ed
A Boltzmann brain is not real, but what’s fascinating about it is that it thinks it’s real, and all the memories and experiences it has are real. But, of course, this brain is not real. But how would such a brain know that its memories...

The Physics of Life (ft. It's Okay to be Smart & PBS Eons!)

12th - Higher Ed
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.

The Arrow of Time and How to Reverse It

12th - Higher Ed
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...

The Arrow of Time feat. Sean Carroll

12th - Higher Ed
Why is the past different from the future? Caltech physicist Sean Carroll explains how the arrow of time is not an intrinsic property of physics, but rather an emergent feature.

Why Do You Remember The Past But Not The Future?

12th - Higher Ed
The laws of physics don’t specify an arrow of time - they don’t distinguish the past from the future. The equations we use to describe how things evolve forward in time also perfectly describe their evolution backwards in time. So the...
