What a bunch of BS, yet another field trying to steal the thunder of CS. How often have I had to listen to physicists sneer at CS as not a proper science!

thanks the feeling is mutual since comp scientists sneer at physicists too, just for other reasons

Altough of course you're right, let's play devil's advocate an imagine a world without Nobel prices. Laypeople needs a simple way to know who's who in advanced research fields, without Nobel prices (or any other commitee) we don't get to have that. If people gets to ignore (more) such topics, it's likely politicians, and universities react accordingly, and funnel funds to other enterprises. All these prices (I'd say…

The economics of this topic have always been interesting to me, especially when compared to various other fields. What is there to incentivize people to enter STEM fields, and especially research? As a point of comparison, there are ~540 premier league football players, with an average salary of 3.5 million pounds. (Yes, that's average, not median, but there's less than 20 of them that earn under 200k.) It's not _tha…

If Physicists could split atoms with only their arms and legs with some safety equipment, I bet they would get paid even more than 3.5 million pound salary.

It’s time to consider adding computer science as a category for the Nobel Prize. They have already been awarded prizes for economic sciences and peace, so why not computer science? It's not the same as physics, and its impact on modern life is undeniable

> They have already been awarded prizes for [..] peace

Since 1901.

Obama intervened in the Libyan civil war. The outcome was disastrous for Libya (13 years of chaos and counting, the entrance of ISIS into Libya, the re-emergence of slavery in Libya, to name a few consequences). Obama blatantly violated the War Powers Act, which requires the President to seek Congressional approval for any war waged abroad after 60 days. The act was passed on the tail end of the Vietnam War, to preve…

The outcome was positive for Libya, as it experienced only a fraction of human suffering compared to Syria where the United States did not intervene against the regime. Either way Libya operation was spearheaded by France with Obama joining only reluctantly later.

The US intervened in both civil wars, though in Syria its involvement early on was much more through funding and arming of various armed groups - notably Sunni fundamentalist groups. How you can say that the outcome was positive for Libya is beyond me. The country was utterly destroyed. It went from being the one of the most developed countries in Africa to a war-torn country with competing warlords and open slave markets.

I can only think of major achievements in my (narrow) field of study. What do you think could have reasonably been awarded?

Three off the top of my head: The measurement of the Hubble constant using delay times between multiple images of lensed supernovae. The first transit spectrum of an exoplanet atmosphere. The first directly imaged exoplanet. (They could hand out Nobel Prizes in the field of exoplanets like candy.)

Exoplanet science is not physics, it's chemistry or planetary science. By your logic prizes to teams who send probes to the outer solar system planets could also be given prizes.

I studied physics in the 90s and we had an NNs course, where most of the models were inspired by physics (MLPs was just one). NNs have been used since decades for identifying e.g. the trajectories of particles at CERN. I remember Hinton's work with Sejnowski (who probably should also be awarded). I was actually surprised to find out that Hinton was not a physicist by training Obviously physicists take great interest…

All of physics is modeling but not all modeling is physics.

Not all modelling is physics, but a rather large part of modeling is. My PhD is in complex systems, and you would be surprised by the range of systems we did study. My work was on a more "traditional" field of high dimension fractal surfaces, but we had a student working on public transit models, another on ecological pattern formation, and so on.

My perspective as a PhD in theoretical physics, who's been doing deep learning in the last 4 years:

1. The prize itself makes zero sense as a prize in _physics_. Even the official announcement by the Nobel Prize Committee, taken at a face value, reads as a huge stretch in trying to link neural networks to physics. When one starts asking questions about the real impact on physics and whether the most important works of Hinton and Hopfield were really informed by physics (which is a dubious link to the Nobel prize anyway), the argument stops holding water at all.

2. Some of the comments mention that giving prize for works in AI may make sense, because physics is currently stalled. This is wrong for several reasons: 2.1. While one can argue that string theory (which is, anyway, only a part of high-energy theoretical physics) is having its "AI winter" moment, there are many other areas of physics which develop really fast and bring exciting results. 2.2. The Nobel Prize is often awarded with quite some delay, so there are many very impactful works from 80s which haven't been awarded with a Nobel prize (atomic force microscopy is a nice example). 2.3. It is wrong to look at the recent results in some sub-field and say "okay, there was nothing of value in this field". For example, even if one completely discards string theory as bogus, there were many important results in theoretical physics such as creation of conformal field theory, which was never recognized with a Nobel Prize (which is OK if Nobel Prize is given to other important physical works, but is quite strange in the light of today's announcement).

To finish on a lighter mood, I'll quote a joke from my friend, who stayed in physics: "Apparently the committee has looked at all the physicists who left academia and decided that anything they do is fair game. We should maybe expect they will give a prize for crypto or high-frequency trading some time later".
