Savas Dimopoulos | Particle Physics in the 21st Century - 1 of 2

The discovery of the Higgs particle at the Large Hadron Collider in 2012 completes the Standard Model of particle physics, which successfully accounts for almost all phenomena observed in the universe. Professor Savas Dimopoulos of the Stanford Institute for Theoretical Physics (SITP) will overview this model and some of the deep questions that suggest going beyond it to theories with extra dimensions, supersymmetry, string theory and the multiverse.
Lecture date: November 2, 2016

Fascinating exposition that gives you a good idea of the concept of the standard model with not much more than high-school science. One criticism as with so many videos of college lectures presented to the world is that the videographer is from the school of film rather than pedagogy. So you end up watching the lectures facial expression much of the time rather than the learning points on the board. Sharpen your game up boys and girls, the Professor is teaching not rapping or canvassing for votes. Do not be put off though, this is well worth your time.

Yea. It bothers when taking notes.

I am enjoying it I am hoping to see the symmetry of 16 and 32131125. Seeing that 1014 is 321 divided by 311 times 25. The longer version leading to a 100365. What is this 13 spaced butterfly ?

[@PaulHigginbothamSr]

I believe the biggest failure of the standard model is 1. Prediction of particle mass. 2. Higgs Boson. 3. Big Bang Initiation

[@nathangrant1824]

Excellent. Thank you. Looking forward to seeing more of this.

[@realcygnus]

this dude is an Andrei Linde species (but a less comical version)........superb content ! as usual

[@Hythloday71]

Really great - can't wait for part 2

[@i18nGuy]

Tremendous presentation! Nice summary of the standard model with gauge theory and philosophical overview. Thanks for recording it. I am looking now for more of his works.

[@Monothefox]

1h 49m: "You can tell by their hairstyles, their different philosophies." Good one.

[@andreizimin443]

That's some great material over there. Really important.

[@glutinousmaximus]

Since the making of this video, we have at last had actual evidence of gravitational waves first predicted by Albert Einstein. Relativity continues to pass all tests! (Even if it took a very Quantum-reliant technology to do so) *_:0)_*

[@PetraKann]

Shouldn't the charges of the up and down quarks be +2/3 and -1/3 rather than -2/3 and +1/3 ? Otherwise the neutral charge of the neutron and the positive charge of the proton doens't add up with three quarks inside these particles.

[@lucyoriginales]

🤔 is like to research to create life in outer space. At right spin and rift forces . God is impressive. ... amazing.

[@Nehmo]

If you speed it up to 1.50 in settings, it's not so bad.

[@god_damn9661]

good idea..

[@mendelsm]

OK obviously I am completely missing something - why is the third quantum number for the electron -1/2? Why is it not -1? Is not (SU1) the electromagnetic charge?

[@erwinmarschall2465]

+Michael Mendelson It's the "weak hypercharge" (cf. Wikipedia, take "minority usage" )

[@glutinousmaximus]

The conventional definition of the spin quantum number 's' is s = n/2. It proceeds like 0, half, 1, 1.5 etc. The term 'spin' was chosen by some idiot :0) because it does not relate to any 'real world' experience of spin that we know. en.wikipedia.org/wiki/Spin_(physics)

[@VeteranVandal]

I'm halfway now.

[@kore4hire]

think bigger with the 3 generations there is one more you are missing\. how do you create 3 dimensional range of motion from a 2 dimensional monitor? well you use vector anchor points. XYZ

[@georgegonzalez2476]

Is it just me? I didn't understand a word of this.

[@Fnargl99]

I suspect this is a trial run for a public lecture. if not who is this for.

[@richardcranium4753]

+mrebus It's for me.

[@elifonkonsolakis2521]

+mrebus for me too

[@Fnargl99]

maybe it is for me considering I've watched this multiple times

[@xinyujiao4464]

Science beyond the standard model seems only philosophy. When quantum theory was invented, there were still many unexplained experimental observations that people thought could be explained by classical theory but couldn’t. Physics beyond the standard model is looking for observations that the standard model cannot explain. Ridiculous! Artists explain what does not require explanation.

[@inkeotv]

There are teachers and there are teachers, and this guy and Susskind are among the earlier kind of teachers. Weinberg, on the other hand, is one of the latter kind of teachers.

[@dinoax3354]

wtf yo soy dimopoulos

[@MrAndreX73]

Time 1:06:43 to 1:07:37...Amazing X73-ANDRE' = 76 MR.ANDRE'-X73 = 107 ANDRE' HARRIS = 115 the birthday of a GOD 7/10/1973 76 + 107 + 115 = 298 298 x 3 = 894 894 + 7 + 10 + 1973 = 2884 8 + 8 = 16 1 + 6 = 7 4 + 2 = 6 comes out to be 76 X73-ANDRE' = 76 76 - 73 = 3 Awesome video, cool physics teacher.

[@Oners82]

+X73-ANDRE' What the hell were you smoking when you posted that lol?!

[@exedeath]

Check his channel and you will know the answer.

[@VeteranVandal]

@@Oners82 surely tripping

[@Hythloday71]

Really great - can't wait for part 2
