Quantum Mechanics - Part 1: Crash Course Physics #43

What is light? That is something that has plagued scientists for centuries. It behaves like a wave... and a particle... what? Is it both? In this episode of Crash Course Physics, Shini introduces the idea of quantum mechanics and how it helps us understand light. Also, there's this thing called the ULTRAVIOLET CATASTROPHE!

My mind to me: Did you understand?
Me: Yesn't

"Ultraviolet Catastrophe" is what I call it when I get a really bad sunburn.

[BangMaster]

I am no Physicist or Engineer, but i gotta say that Physicist have to be some of the smartest minds on this planet, even smarter than Doctors, and other Scientists
They have to have knowledge and deep understanding of Mathematics, and apply it to nature, and be able to think abstractly,
Physics literally means, knowledge of nature.
Thanks to all the great minds studying nature, and helping Engineers build a better future so our human civilization can advance as a whole for the best.

For anyone looking to do reading on the subject but in layman's terms that won't overwhelm you, I highly recommend Quantum Physics What Everyone Needs to Know by Michael G. Raymer. Everything she has discussed in this video is explained in the first chapter of the book, so after reading that chapter and then coming to watch this video, I feel like I understand and can keep up with what she is talking about. Also, I highly recommend you take notes as you read. This will help the information stick in your head as you read, and you won't feel as lost because when you don't understand something fully, you will know as you are trying to take notes on it. This sort of comprehension check is crucial to those of you serious about understanding these topics!

If Quantum mechanics hasn't profoundly shocked you, then haven't understood it yet....! -- Neils Bohr

I completely understand you guys are trying to make videos less than 10 min, but I wish there was a way to slow down these explanations. Great video nonetheless

[Jankolli]

Time to cook my brain and spend the next 5 hours reading about particle physics, black holes, string theory etc.

[lamb]

intruiging how im currently failing normal physics but watching videos on quantum physics

[landogarner]

I wish youtubers would slow down their delivery. Especially when trying to absorb complex information like this. It makes it hard to follow when there is just a constant stream of words.

[Yathuprem]

Einstein is like everywhere in Physics.. !!

[BirdofHerms]

I felt smart until i read the comments, There goes 2 IQ

[niokpanda]

PLEASE PLEASE LET QUANTUM PHYSICS SUB SERIES BE AS LONG AS POSSIBLE!
Hopefully they can cover schrodinger's equation also, and the function thingy that looks like a pitch fork.

[dovahkiinskywalker]

I'm happy that I found this channel though. It never hurts to learn... after all knowledge is power. Remember that friends.

[tahasilat]

People: She talks too fast
Me: Watches video at 1.25x speed

[galvaton]

She's explaining Quantum Mechanics in a simple manner; I'm just like "I like turtles."

[buckybarnes]

you guys really need to simplify these crash courses even further than you already do. I feel as though you are speaking to your contemporaries instead of us out here in the peanut gallery. I'm fairly "educated" -- even got an A in physics 101 in college. but I swear to God I am totally lost when I watch these videos. and I LOVE watching these! the equations are especially difficult to understand, even just on a general level. then again, I'm an artist and I am right-brained. so...

[bhuvansun]

woah, you're rapping it so fast that I have to slow down the video to be able to think and get this information into my brain😶

[mattcoleman]

First I want to address that if she was my quants professor. I would be an A student.
