Let's explore why black body radiation was one of the most puzzling concepts of the 1900s. And in this series, we will see how it eventually led Max Planck to the quantum revolution!

Chatpers:
00:00 Intro
02:02 We are all glowing!
04:04 Why can't we 'see' the glow?
05:24 Why care about black bodies?
08:09 How did we build a perfect black body?
08:44 Just like this perfect web building tool!
09:55 Here's how we built the perfect black body!
12:11 Black body radiation graph
15:08 The first awesome law (Stephan-Boltzmann's law)
15:34 The second awesome law (Wien's Displacement law)
16:08 How we can measure sun's energy output!
16: 49 The perfect black body we ALL have access to

It's an absolute pleasure working with you Mahesh! Had a lot of fun creating this video :) Loved every bit! 🔥

Good stuff man! I never properly understood this concept! Thank you!

[eljando]

As a new physics PhD student I cannot express enough how much these videos fill in my gaps of intuition that I didn’t get in undergrad. I appreciate your work!

[timchallenge]

This has very quickly become my favorite science channel!

[GFClocked]

I like this guy. Just has that energy that makes you excited to learn

This channal really is up there in being able to break down and explain so many complex concepts, in a way that's understandable. all the while not simplifying much at all.
(talking about the channal as a whole.)

[krishnannarayanan]

just as we started this unit in university, you uploaded. Thank you so much, your videos are very nice, I like how you talk to the scientists themselves, and make sure people understand the concept. I'm one of those kids who always wanted to have the intuition of how it all pieced together while others just wanted to get past the exam and were thinking like "something something". tysm!

Best way to etch anything in your mind, is to try to explain it to others, and "listen" to yourself.

Crazy to think that this law is probably the reason why humans (and other life) evolved to see the specific wavelengths of light that we see

Thank you mahesh.... It was a confusing topic for me .. And you made it feel soo easy... ❤

[kunal_.]

what a insightful explanation!!!
I am in highschool while I hadn't the full information about the black body radiation graph.
Now it is crystal clear to me.

[bilbol]

This is the one. The one I've been waiting for. Thank you for all of this, Mahesh.

[kriswiddison]

I have dabbled in thermodynamics for years and have read many papers on blackbody radiation. You are the first one to explain why the hole is part of an approximate perfect black body. Thanks,

[himanshuagrawal]

Your technique is so amazing. I am gained my interest back in physics.

[nickdegroot]

Awesome, can’t wait for the next videos in the series!!

[SethLynch.]

Cannot wait for the other vids, these truly make my day. Keep it up Mahesh

[TobiasGronbach]

So much love and effort in these videos! It's so interesting! Thank you!

[ryanpmcguire]

You are the BEST teacher I have ever come across. Pure humility, and that's why your explanations are to clear.

[daveveale]

Love these videos! Such an energetic engaging way to teach us all
