### Prof Collins explains string theory

Prof Emeritus Walter Lewin has been an excellent physics instructor who loved to include truly physical demonstrations of certain principles, laws, and concepts.

After you understand string theory, don't forget about inertia, either. ;-)

When the SJWs fired him and tried to erase him from the history of the Universe, a vacuum was created at MIT.

The sensible people at MIT were thinking about a way to fill this vacuum. After many meetings, the committee decided to hire a new string theory professor who is especially good at teaching, someone like Barton Zwiebach #2 but someone who can achieve an even more intimate contact with the students.

At the end, it became clear that they had to hire Prof Collins and her mandatory physics class on string theory is shown above. It is not too demanding even though e.g. the readers of texts by Mr Smolin or Mr Woit – or these not so Gentlemen themselves – may still find the material too technical.

But the rest will surely enjoy it. ;-)

Someone could think that this affiliation with MIT is just a joke but I assure you that Dr Paige Hopewell from the Bikini Calculus lecture above has been an excellent nuclear physicist affiliated with the MIT. While at Purdue, she would win an award in 2007, and so on.

1. That's not fair Lubos, you know most of your readers are male, and with testosterone, they will be compelled to click on sexy pictures ! ;)

2. Sexy pictures, Philippe? These are symbols for Schrödinger's and Einstein's equations, and the integral signs. Maybe your fantasy is overheating! ;-)

I don't know whether most of my readers are male, or older than 70 years. As far as I am converned, most of them may be like Shannon or Ann or similar to Prof Collins. :-)

3. Thanks for the nice video Lubos, i feel very clearly now that strings are vibrating ! :) I guess that's why i am so hot !

4. Not to forget the classic http://britneyspears.ac/lasers.htm , which is surprisingly good. I find the valence/conduction band diagram halfway down http://britneyspears.ac/physics/basics/basics.htm particularly memorable.

5. They just got us started and stopped before the good stuff!

6. It's like they are teases or something.

7. Off topic: a student of string theory has been expelled from italy accused of supporting jihad. A few days ago, Italy paid 12 millions to get back two ladies who went to Syria to support jihad and got abducted http://www.corriere.it/cronache/15_gennaio_20/terrorismo-espulso-studente-turco-normale-pisa-c294cbd8-a0a5-11e4-b571-55218c79aee3.shtml

8. OK, if strings are *real* can they really have only one dimension?

9. Sure. String theory looks good now, but will it hold up over time??

10. This looks more like the theory of G-strings.

11. I remember when you talked about the fracturing in science and how the other research directions were total flops and how the only reason string theory isn't fully front and central is to do with phoney scientists and media connections (and likely a large amount of nepotism). Everything except the Strings part I already thought myself. Strings I just didn't know that much about. I was really impressed by the list of credentials you ticked off. I felt Science maybe wasn't at the precipice as I had been. I was and am impressed that all the top talent are in strings, the mathematics directly inherits the mantle of rigour. How so many equivalences had been discovered, like de-sitter a range of other things. Black Holes.
But more recently I don't know what to think again. I don't understand why you pour scorn on questions about string theory cannot predict. I want you to be able to talk about it, because that's a real concern to me and I should think most people. If you think that's all layperson poppycock, and you know all is good. Then please for me, describe where you stand in simple everyday terms.

12. I want Phil Collins to explain this!

13. Yeah so?
