How Entropy Powers The Earth (Big Picture Ep. 4/5)
This video is about how we don't just need energy to power our lives, we need *low entropy* energy! Thanks to Google Making and Science for supporting this series, and to Sean Carroll for collaborating on it! This video is about how we...

What is the Purpose of Life? (Big Picture Ep. 5/5)
This video is about how life arose and what its main function or purpose in the universe seems to be. Thanks to Sean Carroll for collaborating on it! This video is about how life arose and what its main function or purpose in the...

Are You a Boltzmann Brain?
Was an incredible drop in entropy responsible for the Big Bang? If that's the case, this would lead us to conclude that a great many other things are possible, including the likelihood that you are a Boltzmann Brain.

Why Do You Remember The Past But Not The Future?
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...

Boltzmann Brain Paradox Explained in Simple Words
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...

Entropy and the Arrow of Time
As we experience it, time flows in a single direction. But entropy, and its description in the second law of thermodynamics, is one of the few physical phenomena to imply an actual arrow of time. Day 16 of our advent calendar:...

Do Cause and Effect Really Exist? (Big Picture Ep. 2/5)
Thanks to Google Making and Science for supporting this series, and to Sean Carroll for collaborating on it! This video is about why there's no such thing as cause and effect at the level of fundamental particle physics, and how our...

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...

Time’s Arrow & EPR
Nobel Laureate Anthony Leggett (Illinois) speculates on how we might re-interpret the famous EPR experiments by flipping the arrow of time.

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...

The Strange Physics Behind the Smell of Rubber Bands
If you've spent any time trying to explode a pumpkin with rubber bands you know that they have a distinct smell to them when stretched, and you have physics to thank for that.

Thermodynamics: Crash Course History of Science
It's time to heat things up! LITERALLY! It's time for Hank to talk about the history of Thermodynamics!!! It's messy and there are a lot of people who came up with some ideas that worked and other that didn't and then some ideas that...

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...
