Re: Go Green

Cuchulainn, how could I deny climate change when my favourite area of science if complex system dynamics? Panta rhei! I don't find that graph scary at all, Marsden. It's just a lot of lines wiggling around some mysterious value. The only scary thing for me is that I don't understand much of what it ...

Re: If you are bored with Deep Networks

He revealed the code. Good and smart move imho. I have mixed feelings about those chat models. Several times I asked ChatGPT to write a piece of code for me. It sometimes made stupid errors but, since I was too tired to code in the first place, I was close to c&p it to my project (once I did to ...

Re: Physicists, Stop the Churlishness

Brave men, war heroes. Similar story about my grandpa. If the family didn't have tons of money (sold their whole land at the time) to pay every scumbag in the local communist aparat, and the infamous Lublin Castle in particular, at least one of my X chromosomes would feel different. It feels so empo...

Re: Physicists, Stop the Churlishness

O’Rahilly? Sorry, I didn’t read carefully. How did you know my dad liked Tubular Bells?! He made me play it on my piano (some Vangelis within his reach he played himself; his instrument was a bass guitar and his band was invited to tour around the US with som big name, but he didn’t go because my mo...

Re: Physicists, Stop the Churlishness

A French would challenge to a duel. An Irish wants to blow things up :-) Maybe nowadays' women are not worth such acts? Ignored, lied to, repeatedly cheated on, treated worse than a doormat, but they keep holding on and begging for not sure what - because clearly there's no love. Some of them turn i...

Re: Go Green

Just watched Guterres of UN and other clueless politicians' exalted scaremongering about the imminent climate change-induced apocalypse. I understand the goal is to offshore all (the rest of) heavy production to China, so they can make sure the West declines enough not to pose any threat to them - u...

Re: Running free

I managed to get a bib for the London Marathon (Apr.21st) My first time there.
Your advices about the race, and the logistics around are much welcome.
And let me know if you're also in.
Nice pub at Narrow Street on your route I believe.

Re: Physicists, Stop the Churlishness

This aspirational English upper middle class... constantly unsatisfied. The happy know no hours (or translating the Polish saying literally, they don't count time). Still, I like the song - but now as much as many people. Money is way better musically imho. Are you more into early or late Floyds? PO...

Re: Delta Hedging P&L

From what I understood, possibly incorrectly, you used historical data on the ETF, call options details and volatility to evaluate a delta hedging strategy. A model in my understanding is everything from GBM to the details of the hedging strategy, to PnL calculations. I was wondering if the performa...

Re: Physicists, Stop the Churlishness

I never asked my cats what they think about the concept of time. They must understand it well since they are masters at calculating time derivatives up to more than second order. Speaking with an unintended and long undeserved tone of an authority (acquired during my PhD research in the field), the ...

Re: Happy St. Patrick's Day!

YCjXkV1aaC8 I stopped colouring my hair blue-black about a year ago, encouraged by my bf. It's copper-red against the sun and curling like the girl's in the video (nothing as beautiful though). Maybe I'm Irish :-D https://cats.com/wp-content/uploads/2022/11/irish-cat-compressed.jpg BTW, all ya sham...

Re: RIP thread

I shared with this author the penchant for observing the world, rather than prodding it with measuring devices or even a camera lens (a caution I adopted after studying quantum physics - collapse, bias, and all the observer effects we can’t even know :-D ) I believe I once made a risky statement he...

Frans de Waal
I don't know if he was an inspiration, but surely a refuge for me - in his books, research and anonymous social media interactions.
Now sure if anyone here could bother reading his books, but here they are:
