    His explanation of broken symmetry as part of the whole symmetry is very good. First I have ever heard this explanation that helped me very much.

    I love your teaching Prof Alex! I'm truly thankful that I can get information about the universe mathematically!

    This professor is quite good! I’m taking a class in Particle Physics for my master’s degree and this has illuminated quite a bit :) Thank you!

    Perhaps early in the universe during inflation the broken symmetry DID produce a positron, but it when through a phase transition and converted back into an energy field INSIDE of spacetime causing what we call dark matter. Like Hawking Radiation once energy converted to electrons and positrons the matched pairs instead of inhalating, the positron somehow was transferred into spacetime causing it to hit its elasticity yield point. So the electrons went on to make matter and the positrons went on to make potential energy in the form of an "empty" gravitation field-dark matter...

    Proton-proton collision or proton decay etc., involves production of W-boson or Z-boson, hiring a lot of energy from the fluctuation of QF, to be immediately repaid. Where as a quark or a gluon have few Gev energy, their collision process or decay involves borrowing 80 Gev from the QF. As such the QF plays the most important role in particle production.
    However, Maldacena believes the entire universe acts like a QC (not fully developed, except for basic mathematics of superposition of states, while self-error correction etc. remains a mystery). The elementary understanding is as follows: The QF can self simulate intelligent conscious 'observer', collapsing the field into fine tuned particles (matter and energy) creating life, that also a functions as a QC. Understood noy by physics but biology. We damage 50-70 billion cells daily the are repaired/regenerated with 99.99 % efficiency and at lightning speed, implying the elementary level of our comprehension of that which is incomprehensible.

    very good, just one observation, I consider that the unstable minima occurs at V(@) = 0 , and you cross the potential curve V, at some point above the zero point. greetings from Fresnillo Mexico

    Wasn't there a video in this series where you introduce the concept of symmetries in physical systems?
    I seem to remember watching about half of it, but now I can't find it.
