Re: norway

"Det er registrert litt nysnø på Sognefjellet, Strynefjellet og på topper på Hardangervidda og i Jotunheimen, men man måtte nok over 1500 meter for å få snø, sier vakthavende meteorolog Eldbjørg Moxnes ved Meteorologisk institutt tirsdag formiddag."

Mountainous regions. Snows all year round.

Re: Differential equation with a random walk forcing

In space.
Cool papers! Thank you. I only don't understand why fractional derivates / the Levy flight models memory effects (from the paper about fractional SIR). Levy flight flight (specifically the clustering) is like Brownian motion + memory? (Sorry if I'm talking nonsense.)

You look terribly intellectual in those glasses, what .. like PhD student in Irish literature. What do you think of the work of James Joyce?
He wrote nice fractals.

Re: Quantum everywhere

I have it separated in my mind too. Sometimes I remember a place but not sure when I was there. Sometimes I know I was somewhere, but can't remember anything about it. Years ago ISayMoo and I went for a mountain trip, which I got completely erased from my memory shortly after returning from it. I ke...

Re: Quantum everywhere

"Oddly, I was just flipping through some lecture notes on that very topic this afternoon"

Quantum telepathy! No joking, it exists. I'm wondering if Schelling's focal point, which is 100% classical, cannot be understood as quantum telepathy... but I'm wondering about too many strange things.

Re: Differential equation with a random walk forcing

I dunno which split-step method it is :-( I just solved it in two steps. If I could use your know-how once more, how do you deal with fractional derivates numerically on the lattice? On a 2D lattice, can I simply add the vertical and horizontal fractional derivatives like in the case of Gaussian dif...

Re: Quantum everywhere

I've heard that quantum "computers" are getting popular in finance (quantum annealing in optimisation problems) - true or not? It offers quantum speedup (N^2 vs classical N), because of ballistic transport (vs classical diffusive). So at least there you do Hadamard walk. Anyway, I expected to hear a...

Re: Are You Ready for Some Rugby?

But we lead in rugby, right? I think British science is cargo cult science: people who achieve success pat on the back and praise each other, so we do the second part and expect a miracle. Apropos satellites, I wonder if this is true: 'We've bought the wrong satellites': UK tech gamble baffles exper...
