Bohemian gravity!

Tim Blais  explica la teoría de cuerdas… y para ayudar a entenderlo, se añaden enlaces  a todos los conceptos que aparecen…

Is string theory right?
Is it just fantasy?
Caught in the landscape,
Out of touch with reality
Compactified
On S⁵ or T*S³

Space is a pure void
Why should it be stringy?
Because it’s quantum not classical
Nonrenormalizable
Any way you quantize
You’ll encounter infinity
You see

Quanta
Must interact
Via paths we understand
Using Feynman diagrams
Often, they will just rebound
But now and then they go another way
A quantum
Loooooop!
Infinities will make you cry
Unless you can renormalize your model
Of baryons, fermions
And all other states of matter

Curved space:
The graviton
Can be thought of as a field
But these infinities are real!
In a many-body
Loop diagram
Our results diverge no matter what we do…
A Quantum Soup! (any way you quantize)
Kiss your fields goodbye!
Guess Einstein’s theory wasn’t complete at all!

I see extended 1-D objects with no mass
What’s their use? What’s their use? Do they give us quark plasma?
Can we minimize?
What functional describes this
String?
Nambu-Goto! (Nambu-Goto)
Nambu-Goto! (Nambu-Goto)
How to quantize I don’t know
Polyakov!
I’m just a worldsheet, please minimize me
He’s just a worldsheet from a string theory
Reparametrized by a Weyl symmetry!

Fermi, Bose, open, closed, orientable?
Vibrations
Modes! They become particles (particles!)
Vibrations
They become particles (particles!)
Vibrations
They become particles (particles!)
Become particles (particles!)
Become particles (many many many many particles…)
Modes modes modes modes modes modes modes!
Oh mamma mia mamma mia,
Such a sea of particles!
A tachyon, with a dilaton and gravity-vity-VITY

(rock out!)

Now we need 10 dimensions and I’ll tell you why!
(anomaly cancellation!)
So to get down to 4D we compactify!
Oh, Kähler!
(Kähler manifold)
Manifolds must be Kähler!
(Complex Riemannian symplectic form)
If we want to preserve
Any of our super-symmetry!

(Superstrings of type I, IIA and IIB)
(Heterotic O and Heterotic E)
(All are one through S and T duality)
(Thank you Ed Witten for that superstring revolution and your new
M-theory!)

(Maldacena!)
(Super-Yang-Mills!)
(Type IIB String!)
Dual! Dual!
(In the AdS/CFT)
(Holography!)

Molecules and atoms
Light and energy
Time and space and matter
All from one united
Theory

Any way you quantize…
