Neil deGrasse Tyson Explains Why You Can’t Reach Absolute Zero

You’ll learn why there’s really no limit of how hot you can make something. On the flip side, we dive into why making things colder is a different story. How do you create a place where there is no heat? You’ll find out more about the Kelvin scale or absolute temperature scale.
Neil takes us through the process of cooling things down. Discover the differences between temperature and heat energy. We explore the vibration of particles and dip our toes into Maxwell–Boltzmann distribution. Then, Neil tells us why we can never philosophically or theoretically reach absolute zero.
To wrap things up, we investigate what happens when quantum physics take over. Discover more about superfluidity. All that, plus, you’ll hear about the Bose–Einstein condensate and how we can “shape-shift” matter.

When Lord Kelvin decided to use the same intervals as the Celsius scale he became an instant friend to all physics students ever to exist
-
Doctor: Your kid has a fever Neil: Your kid is moving faster
-
Let's credit Chuck for being the best host there is as he's both entertaining and relevant.
-
I know almost nothing of physics besides what I remember of my high school physics class a decade ago, but Neil has inspired me to learn. I look back and regret not paying attention to things that are so fascinating and literally explain the universe! Neil has inspired me as an adult man to go back, and purely for fun and for a desire for understanding, study physics and science in general; what a great educator
-
Give a definition of absolute zero Me: Hold my bank account
-
Zero Kelvin: can you stop for a second? Atom: no
-
It is so contagious the excitement of Neil. And Chuck is great at throwing jokes to lighten up the concepts. I love this channel ❤
-
It is such fun to watch the two of them. They harmonize so well - and Neil can explain the things so well.
-
Chuck: "That's so cool!" doesn't even realize the joke he just made...
-
The amount of impact you have had on humanity should be measured in tysons. Edit: changed to lower case t due to popular demand.
-
As a Mechanical Engineering student in my senior year, this surely added something to my knowledge.
-
I most say Neil makes every lesson fun. Imagine having Neil as a professor 👏👏
-
Chuck looks like he's chilling around 420° right now
-
Chuck's absolute brilliance is so completely underrated.
-
Neil deGrasse makes Physics be soooo simple. I love his explanations. Thank you Mr. Neil for bringing Physics into the ground so we can all learn more and more with the honey you put on top of it... 👍
-
This is like a teacher teaching a class clown that actually pays attention.
-
Absolute Zero is just the number of times I’ve been laid this year.
-
I love this ability Neil has that is taking extremely long and complicated questions and making them simple and understandable for the broad audience. Plus his sense of humor is 🤌🏻🤌🏻

But this is how exactly how I teach. There are certain common speeds at which kids and students hear something, grasp it and then internalise it. A good teacher will find that rhythm and will never go too fast or too slow. If you go too slow, your intelligent kids' minds will wander and they will end up missing bits of information or fail to form a cohesive picture. If you go too quickly less intelligent kids will just fall behind because they never have time to process and internalise information.

"I don't want to be remembered for anything..." Too late for that Professor. You passed that milestone many, many years ago.
