2009

Dirac biographer @grahamfarmelo opines that P.D. talked nonsense about economics in Stockholm. That's correct about paragraph 3. But not 2.

4:11 AM · Oct 5, 2009

I will risk challenging Graham. Dirac's larger point is OK but wrong in the specifics (as with the positron/proton flub).

4:23 AM · Oct 5, 2009

First of all, by 1925 work of Algerian economist Francois Divisia, Abelian gauge potentials had already entered economics.

4:28 AM · Oct 5, 2009

Additionally, Vilfredo Pareto's move towards ordinal utility can be seen as imparting a non-abelian bundle structure to welfare.

4:33 AM · Oct 5, 2009

At issue in economics is that the gauge potentials are so far more determined by Levi-Civita than Yang-Mills type constructions.

4:36 AM · Oct 5, 2009

If @grahamfarmelo, in 10Y the representative consumer w/ seasonal ordinal tastes is modeled by a gauged quantum string, will Dirac be right?

2023

who's your favourite economist?

11:07 AM · Jan 30, 2023

François Divisia or Ken Arrow or Paul Samuelson or Satoshi or Ronald Coase etc.... would be easy to defend.

But Graciela Chichilnisky or Bert Balk would be more interesting offbeat choices I could defend. I don't think they got their due for what is coming in mathematical econ.

5:01 AM · Jan 31, 2023

I would’ve guessed you liked Ken Arrow, Eric. The work for which he won a Nobel Prize in 1972, seems right up your street. Tbh having learnt some of Ken Arrows works in my final year of my economics degree, it completely changed the way I looked at elections + institutions.

11:07 AM · Jan 30, 2023

He was very supportive of me. If I had to make a single choice it might be him or Samuelson.

2:24 AM · Feb 1, 2023


Yes, but when I said ‘brightest minds’ I meant it.

8:43 PM · Feb 13, 2023

Arrow, Frisch, Samuelson, VonNeumann, Nash, Friedman, Smith, Mill, Divisia, Coase, Marshall, Fisher, Debreu, Tinbergen, etc.

I have deep issues with economics. But I don’t think I understand your point.
