Quantum Mechanics and the Schrödinger Equation

Okay, it's time to dig into quantum mechanics! Don't worry, we won't get into the math just yet, for now we just want to understand what the math represents, and come away with a new and improved view of the electron as both a circular standing wave and a cloud of probability density. Spooky! Let's introduce the Schrödinger equation!

Check out "Is This Wi-Fi Organic?", my book on disarming pseudoscience!

Me: doing absolutely nothing.
My brain: "He knows a lot about the science stuff. professor Dave explains!"

About a year ago I dove deeply in quantum mechanics, almost as a hobby. Determined to understand the significance of the finding the Higgs-Boson particle, and why the construction of the LHC at CERN, led me into the depths of quantum mechanics. Not once in the dozens of hours I spent reading about quantum mechanics did I see the simplicity of the standing wave of an electron, and its relationship to the Schrodinger equation, like I just saw in less than 7 minutes. Thank you for taking the time and making the effort Prof. Dave!

Professor Dave, I am an undergrad physics student in the middle of their 3rd semester of physics, who is about to enter the world of quantum mechanics. I just want to say that you truly have a gift for communication and teaching. The way you break down complicated concepts into manageable parts is unmatched by anybody I have ever since.

From humiliating flat-earthers to bullying James Tour, I cannot get enough of your content. I hope there is lots more to come.

me a 14 year old just learning about physics in my free time instead of doing my biology homework.

Update: working on college applications for aerospace engineering (october 2023)

This is like one of the best YouTube channels I have ever discover

[anirudhnatarajan]

Totally coincidental, the video is approximately 2*pi minutes long😂

[RbbT]

This is by far the best description I've ever seen on Quantum Mechanics and the Schrodinger Equation. Simply brilliant Professor Dave! It's the first of your series I've watched and it most definitely gives me a reason to subscribe and watch more.

Thank you very much.

As a physics major, this is one of the best explanations of wave particle duality I have come across, and while I havn't actually messed around with the schrodinger equation yet, i have done the double slit experiment, worked with standing wave equations, ect. This is brilliantly concise and amazingly informative. Thank you sir.

[davidwang]

I’m doing chemistry and all the textbook stuff flew over my head. This video was so helpful connecting all the different ideas together. THANK YOU!

[xzavaire]

The visual you added with the electron energy levels and standing wave would have made learning certain sections of chemistry and physics in college so much easier. When my kids ask about wave nature im pulling this video up.

[CrazycruxGaming]

This is the best explanation of quantum energy levels I have ever seen. It makes so much sense that a photon can cause constructive interference when it collides tangentially with a circular standing wave. Thank you!

[marija]

god bless this, you're saving my physics grade!!

[xkdjdnskdnscndjdj]

All of your words pierced straight into my brain without meeting any conflicting thoughts, it's almost like magic.

[gabmasterson]

man I just had a modern physics exam this morning & spent all night last night watching this playlist. if it wasn’t for your videos, i wouldve failed that exam but i felt so comfortable in answering all the problems. thank you SO MUCH

[mjbrennan]

I found you while doing my undergrad in medicine and now that I have my degree, I still keep coming back for more. Thanks for the work you do on these.

[davidhoot]

This is the single best explanation of the difficult concepts of wave particle duality and the quantum nature of energy I have ever heard. Absolutely brilliant! Thank you.

[christianfaust]

as a German Engineer I am really jealous how marvelous American scientists can explain such complicate matters...Thumbs UP! ;-)

[AdityaKumar-ijok]

Thanks sir, i was confusing in my chemistry classes as to why the energy is quantised, the book tells that it is quantised but didn't tell why it's so. thanks a lot again.

[nachannachle]

Such a smooth presentation: you stick to your main point, which is very rare in Physics videos (most presenters tend to cloud the matter with to many tangents/cliffhangers)!
I really like the clarity of your language and the use of colour codes to guide us through your talk.
Now off to Heisenberg's...

[alexhill]

Love the analogies and annotations as the pictures and visual aids change, providing clarity about a very messy, conceptually complex equation
