> Attosecond pulses: Flashes of light that last only a few billionths of a billionth of a second. In one attosecond, light covers a distance of 0.3 nanometers (one nanometer is one millionth of a millimeter). This corresponds to the diameter of a water molecule.
> Femtosecond pulses: Flashes of light that last one millionth of a billionth of a second – about one thousand times longer than attopulses.
There was a nobel prize for the Higgs, but SUSY and all the other sorts of things particle physicists hinged on...well that didn't peter out, did it?
I thought for awhile those guys got lucky and skip office politics.
Then I realize that PhD level IQs + pressure to get into the fancy journals means that the politics is 古典小說 tier.
There is a famous formulation of this known as Sayre's law[1], which is often stated via the quote "In any dispute the intensity of feeling is inversely proportional to the value of the issues at stake. That is why academic politics are so bitter," which wikipedia attributes to Charles Philip Issawi.
That's truly amazing that we can measure at that detail. Mind blowing actually.

(On a side note, Bing chat already knows now that she won the prize. Color me impressed.)
It actually doesn't. Bing searches for your query and uses plain old search results as extra context for the actual LLM. GPT-4 still has the same knowledge cutoff as when the model was last trained.
Here's what it feeds to the model when searching for "nobel prize in physics 2023":

This year's Nobel laureate in physics lectures us after (!!) being notified of her win!!
Like no shit, you try to carry on a lecture while like 20 different journalists try to call you! The youth of today! ;)

I actually think this work is cool so I can't explain that passing image. Sometimes our brains are weird.
Same as you though, does it really matter if we can't fucking keep them working in our universities...
In his novel Budapest, the Brazilian novelist Chico Buarque writes that Hungarian “is rumored to be the only tongue in the world the devil respects.”

Can someone elaborate on these weights ? Are there occurrences where the attribution weights are different between laureates ?
I was thinking along the lines of: 1 attosecond corresponds to .3nm, so very short wavelength, so very deep UV.
>The Nobel Prize in Physics 2023 was awarded to Pierre Agostini, Ferenc Krausz and Anne L’Huillier "for experimental methods that generate attosecond pulses of light for the study of electron dynamics in matter"
There's also a link to press release: https://www.nobelprize.org/prizes/physics/2023/press-release...

Eg since only 3 people can win a prize, you can have cases like Francois Englert and Peter Higgs winning the prize for the Higgs Boson despite 4 other scientists having published papers on the same thing around the same time, and the scientists at the LHC who actually confirmed its existence.
Similarly, a work can have won a prize, but if one of the authors passes away before the nomination is made, that person misses out on the title.
It does, but the politics and favoritism is happening within a heavily selected group of very, very competent people. Plenty of people get snubbed for petty reasons, but they get snubbed in favor of others who are also doing Nobel-worthy work.

I understand (at an undergrad level) superimposing light waves. But this blows my mind:
At the same time, Ferenc Krausz and his research group in Austria were working on a technique that could select a single pulse – like a carriage being uncoupled from a train and switched to another track. The pulse they succeeded in isolating lasted 650 attoseconds
This is using Chrome.
Some people are proud of where other people work, regardless of where these other people were born.
These are very different views of the world /shrug
The stick however, it remains.
I guarantee the university would have let her expense a laser pointer, but those break, run out of batteries, and can be harder to place accurately or spot. Sticks just work.
They're about court life and conflict, so of course they're full of court politics and intrigue
I just don't know what "古典小說 tier" means since I don't remembered they're known for "high-intelligent politics".
The wavelength at the size of a watermolecule in the range of Exahertz x-ray rather implies very precise laser pulses because the focal point is proportional to the wavelength. It is also relevant for energy transfer into molecules at resonant frequencies.
from the last paragraph linked above:
> For example, attosecond pulses can be used to push molecules, which emit a measurable signal. The signal from the molecules has a special structure, a type of fingerprint that reveals what molecule it is, and the possible applications of this include medical diagnostics.
Basically it's a more precise higher energy X-Ray laser.
I believe the fast turning on and off is a byproduct of a basic method (high-harmonic generation). They do stress the importance of short pulses, but this again may have to do with decoherence of the focal point and not so much the speed of electrons inside the molecule, which is only a model (i.e. relativistic) and remains to be investigated with this new method.
The Big 4 novels contain a lot of public servants.
