13. Physics of D-branes, Part I

[@levk4321]

Great lectures, thanks a lot for making them available to the public! Would be nice to have a link to the home work sets.Please provide it if possible so that we could do the assignment and learn a bit deeper.

[@mitocw]

Problem sets with solutions (and other course materials) are available for free on MIT OpenCourseWare at: ocw.mit.edu/8-821F14. Best wishes on your studies!

Great lecture!

From the "hidden variable" idea for mathematical models:- If the analysis of a mathematical model for time and space is based on the "sum of histories", "path integral", or temporal superposition, depending on the introductory terminology used, then a D-brane can be considered to be a type of quantum chemistry, resulting in a general state where the bonding ratio of the brane structure is related to Euler's formula, as an identity of the superimposed wave connection, ..generating the geometry of measurable quanta from apparently smooth continuity. The Power Pi-i ratio for "e" is "imprinted or embedded" in the cyclic/path nature of time so as to define the mechanism of brane structure, ..in the linear-radial "string" of the number line spectrum. (Superimposed multiples of a mathematically constant ratio becomes the wave band combination of linear-transverse orthogonal geometry/probability) Eg if a plastic ruler represents linear graduations of an arbitrary set of ratios in the localized part of the universe, then its reciprocal relationship with the universal quantum state, is one continuous existence; a permanent, quantized, bond in time of relative timing duration/frequencies. Or "visually" equivalent to a vibrating rubber band/brane.(?) Ie, looking at the macro infinite vanishing point, from the internal micro vanishing point, one perceives an apparent transverse sight plane image of bonded points orthogonal to the line/(string-line), of sight. (All observable)(?)

Why are we drawing arrows on the string (30:30)? What do these arrows indicate?

[@emanuelebinetti6499]

I believe they go from sigma=0 to sigma=pi, it's a way of keeping track of the string orientation.

Can I just say that I just love how this was filmed.

[@jkadoodle]

I think they used a camera to film it

mit please i need the quatum field theory course and quatum field theory in curved space time please i going to cry if mit ocw dont add it (i have 17 teeen and im mexican so if mit ocw want to give me a scholarship im going to be the most happy in this world

[@naghdezartoshtian]

you are 17 and understand qft in Curved spacetime ?

[@ROTYrightn0w]

You think the portals used in Loki are representations of P or D-branes? Its posited that the TVA is located in the quantum realm... would be a cool easter egg.

Non ci ho capito nulla. Vabbè, ci ho provato, dai.

I apologize for any negative comments were in on your page the police have tapped my phone and have been giving out my information on my phone and what I look at on the internet to the A1 people and they have been harassing people on KZbin and on the internet so again I apologize for any problems or negative feedback that you have been receiving
