Hidden assumptions

All theoretical physics is based on linear algebra.

A little over two weeks ago, I wrote about “the AI apocalypse”.

Way back in April 2015 I had a long discussion with Marni Sheppeard, during which she told me about the Koide formula, relating the masses of the three generations of electron, and I told her about my formula, that relates these masses to the proton and n…

The metaphor “hot air”, I suppose, derives from a euphemism for a four-letter Anglo-Saxon word, that is nowadays rarely considered worthy of euphemising, so that the nature of this euphemism is lost in normal usage.

Classical Newtonian physics is deterministic, and works with real numbers.

Yesterday I was busy editing my latest paper on the group-theoretical foundations of physics.

My last post seems to have been misinterpreted as saying that I throw everything away except the finite group.

The “gauge group” of the Standard Model of Particle Physics is a Lie group U(1) x SU(2) x SU(3), modulo Z_6 to get rid of unwanted central elements.

According to Aristophanes, ancient Greek frogs used to say “brekekekex koax koax”.

For years I have struggled to find any ideas at all for explaining the mixing angle between the down and bottom quarks.

It is well known that Dirac predicted antiparticles.

The phrase “intrinsic spin” is, of course, an oxymoron.

Back in the Good Old Days of E8 theories, when I first met Corinne Manogue and Tevian Dray, they began their construction of a model by putting the Lorentz group (in the form Spin(3,1)) in the middle of Spin(12,4), leaving Spin(9,3) which they split into…

Or, to put it another way, I am a pure mathematician.

If it really is true that the group SL(4,R) describes the symmetries of spacetime on all scales, then it is necessary to quantise SL(4,R).
