Prof. John Baez: Unsolved mysteries of fundamental physics

[@JerryMlinarevic]

You should have put the camera across the street!

[@moshecallen]

What's with the buzzing noise in the audio?

[@richardmckay9958]

The CMB

[@deadsi]

Yes,the Cellular Mobile phone in his Back pocket

[@larryg2320]

Very interesting ! I just wish the camera person had focused on the screen presentation. I can not read most of the slides in KZbin.

[@zes3813]

wrr

[@keithdow8327]

There is a link to the slides just below "CUPS".

[@apareek96]

Here is non physics trivia. Prof john Baez is a cousin of famous singer Joan Baez.

Amazing video!

[@thedouglasw.lippchannel5546]

How about CIG Theory?

[@justinjohnson1766]

Keep uploading more of this everyday genius.

[@stevenverrall4527]

He didn't mention all the different plausible interpretations of QM.

[@David_Lloyd-Jones]

I don't think that's at all fair, Steven. Every one of them, and every one not yet posited, fits neatly into the package of stuff that doesn't blend smoothly into the Standard Model. Or do you have your own interpretation that doesn't fit, that would blend, but there isn't enough space in this narrow margin?

[@cichy187]

time is at least 2 dim because you need two humans or creator of obj to create at least 1 dim which is able to see or hear the big bang

[@clairecsmith7609]

Maxwell is 1 of my favourite scientists.

[@David_Lloyd-Jones]

Good to the very last photon.

[@JohnDoe-ft2nc]

What if unknown material exist?

[@kpawan75]

Wonderful Lecture

[@David_Lloyd-Jones]

A lazy and undisciplined ramble. Fortunately, Baez confines himself to a single, trivial and utterly uncontroversial, point, that there is a seam or disconnect between the standard model over "large" scales and quantum disciplines at the extremely small. Did anybody not know this?

[@jasonw137]

we should ALWAYS give up ALL hope >:(

[@TheVincent0268]

It would have been better if we could see the face of the speaker.

Every day a wise man passes a sheep grazing in a field. And every day the wise man thinks “the sheep does nothing except eat grass, what kind of life is that?” One day the man stops and speaks to the sheep, “What are you doing?” The sheep looks at the man and motions to the sun with his hoof and then motions to the grass. The sheep then continues to graze. Awestruck, the wise man sits down and thinks about what the sheep had done. After a while, the man gathers himself and says to the sheep, “I see now: matter in the sun becomes light and some of that light gives life to the grass. You eat the unconscious grass and now the matter in your body is conscious. You are making the universe conscious.” The sheep stops grazing and looks at the man and said, “Yes that is true, and what are you doing?”

Fine structure constant 1/137.036=ke^2/gm^2 and m=(ch/g)^0.5=2.17647*10^-8 kg unite c, h, g from SR, QM, GR together.

Ive got 16 mins in and it seems very cool, Im very jealous if any of you can get it from an academic point of view but my amateur interest keeps me with my toe dipped in the water.

[@DDDelgado]

47:00 the update would be that axions apparently have been found, which is a dark matter candidate.

[@tenbear5]

Reductionism is redundant.

[@jimmyvalentine8690]

👏👏👏👏👍👍woww... that's interesting

[@TheoriginalGrumphy]

Why is the world not twodimensional. Is that not a stupid question? First of what is a dimension? Is it a measurement is it a pointspace is it a bit. No matter what it is it needs to include something. And that something is per definition at least one bit of information. But that bit is only valid if larger systems are around. Or forces, but forces need something to work by from a standard view. So you will never get anything but a bit from a bit. Unless you got bigger systems working in 3d space. So actually the first of our two dimensions only exist in our minds. Unless the Univers is mathematical and then we are back again. Because math is reason and reasons.

[@clarkh3314]

This is why you should be formally educated in logic. All you did was say nothing and speak in circles brother.

[@Gringohuevon]

gibberish

[@parthprashar8498]

[@TheNewPhysics]

Einstein's "explanation" about why time is different from space is utter nonsense. That is just a statement that time is an imaginary dimension. plus Pythagoras... nothing else. Even if time were an imaginary dimension, the next question is why there isn't an imaginary force that can propel us around time? If there were, time would again be equal to space. So, again, Einstein blew it and cult members just gobbled up anything he said without thinking. By the way, I know the answer.
