Quantum Field Theory 2a - Field Quantization I

In the previous video we saw how the quantum harmonic oscillator provides a model system in which we can describe the creation and destruction of energy quanta. In 1925 Born, Heisenberg and Jordan presented a way to apply these ideas to a continuous field. (Note: My voice is lower and slower than normal - I was coming down with a cold.)

Best video ive seen on this. So many ppl out there repeating platitudes and really haven't a clue what they're talking about.

I just wanted to say that your videos have inspired me to study physics again after working for 18 years as an engineer. I wish I'd had these tools when I was in university...but it's never too late to learn GR and QM ;) What's awesome is that now I get to teach it to my children, and your videos are a great help. Thank you so much!

I love how you follow the evolution of thought on the topics as you explain them! Makes it so much more motivation by getting both the history as well as the theory! And it makes it easier to grasp actually, as these fellows were excellent thinkers, boiling the concepts down to the essentials!

Remarkable effort by the author. Praiseworthy. Loved all the videos.

Love it. Also, the notion that "curvature in space === curvature in time", up to a constant, is just great.

I like the thorough treatment with references to the original papers on the major concepts. Would have liked to hear though that the electron wave function is not a scaler but a spinor.

On Quantum Mechanics II
by: M. Born, W. Heisenberg, P. Jordan

That was one scary (amazing) line up.

[Cosmalano]

0:42 I thought it was a spinor function not a scalar function?

[adampaxton]

Surely there are also infinitely many frequencies possible for the bound state harmonic oscillator. The difference for the Electric field is that there are *uncountably* many frequencies.

Impatiently waiting for your other videos about quntum field theory. Please provide them as soon as possible. Thank you for your breakthrough

[Cassandra_Johnson]

ty for more! Am I the only on hearing the audio slowed down by like 20%?

[Theox]

The second derivative equals the curvature only if the first derivative vanishes.

[spacefieldtime]

perhaps a prop on Dragnet would be appropriate....

[Roxor]

You sound like you're dozing off in the narration for this one. You're much more alert-sounding in the Thermodynamics 2b video.

[pharaoh]

So they are trying to write an equation for the movement of the "field" of puddles, streams, might rivers lakes and oceans all with one equation, instead of concentrating on the forces with respect of just single molecule or small groups of H2O. A fools errand, mental masterbation.

😂😂 you tell the meaning of vector, as if it is very hard . But skipked many hard terms
