Separately, and sadly, Norm!

Sad to hear -- RIP. Besides, Cheers, there was a memorable Columbo episode of his:

'Beauty' particle discovered at world's largest atom smasher could unlock new physics
Why matter dominates over antimatter in our universe has long been a major cosmic mystery to physicists. 
A new finding by the world's largest particle collider has revealed a clue.

Well, there you go:
How a Secretive Gambler Called ‘The Joker’ Took Down the Texas Lottery (WSJ, Apr 12, 2025)

The serious versions:
Meet the crew for Blue Origin's upcoming all-female spaceflight with Katy Perry

The fun versions:
Katy Perry says she’s going to put the ‘ass’ in astronaut in wild interview ahead of all-female Blue Origin space flight

Looks like a perfect strategy to ruin some good electronics:

What's the answer then?   BGW  + see my download. bearish's counter-example 'works' (escapes BGW proof) because the volatility in that one is not Markov. What works?  Basically, (i) any 1D (Markov) diffusion with generic local vol; (ii) any 2D (Markov) stochastic vol diffusion with volatility SDE (...

Speaking of mandatory political statements in academic hiring (well, I was anyway), 
this just in from the LA Times (Mar 20, 2025):
As Trump attacks DEI, UC bans ‘diversity statements’ in faculty hiring

Well, I am not a fan of RFK, Jr, so won't die on that hill ...
Related, I don't get conservative paranoia about Covid vaxes.

But, as for dismantling the Green New Deal cramdown (mandatory EV's, no gas appliances, etc) -- I'm all in for that one.

How the EPA turned into a Democratic slush fund (WSJ): Trump’s EPA vs. Biden’s Dark Climate Money: A lawsuit may expose how the Democratic Green New Deal really worked. How this works: 1. US is polarized roughly 50-50% into Republicans and Progressives 2. Republicans reject modern science 3. Hence,...

Here was my take on BGW (which has been mentioned) from my first book:

The volatility can be a discontinuous function of S while preserving the result, as long as it only depends on the contemporaneous stock price. That is, the local volatility can jump up when the stock price goes down without making the call delta negative, as long as it jumps back down again if the...

Yes, I thought that would be too much of a hint.

It's interesting that the AI chat boxes haven't absorbed their results.

I’m not even sure what to prompt (-: I can relatively easily imagine scenarios when volatility depends on the stock price and the option value changes up or down. What’s this problem asking about?   If the stock price is governed by a 1D diffusion, you'll be hard pressed to find a negative delta fo...
