Mostly its because Activision/Blizzard is such an obviously shitty terrible company that any deal that sees cool IPs taken out of their hands is seen as a positive thing.

The way we measure angles also revolves around 360 = 60x6, I think because of old base 60 systems.

> Anyway, the point is that the halting procedure in its full generality cannot exist, while each individual busy beaver number can be solved in theory (even if there’s no algorithm that can list them all). I don't understand this p

If you can solve the halting problem there is an algorithm to easily solve the busy-beaver problem and vice-versa. They are exactly equivalent.

Other people have mentioned this already, but halting for Turing machines is essentially exactly the same for undecidability as busy beaver numbers. Here is a quick sketch of a proof: Assume we have a machine (or algorithm) which we input a

The way I feel is that being open minded and intellectually free is great, its very interesting and you can learn many cool things. However once you've learned those things its also important to be clear about them. Lets take something

I think describing my view as putting limits on intellectual exploration is unfair. Intellectual exploration has been done, they went and looked at the formations in Bosnia and were like "yeah those are flatirons, just like the ones in

All those things are indeed possible, and keeping an open mind is generally positive. That said in the specific case of the formations in Bosnia, reputable geologists have investigated them, and have said that they are well-understood natur

As far as the Bosnian thing goes, this is from the wiki article you linked: > Direct study of the site by geologists, archaeologists, and other scientists has demonstrated that the hills are natural formations known as flatirons, and tha

In this comment you seem to be reading "punch up not down" as a very binary, fixed rule, as if it is a being used as a commandment. I don't think many people think of it that way. Of course you can make comedy about poor and

For anyone who has had their appetite whet for Indian pickles, the book Midnight's Children has pickles as an important secondary plot point, and the vivid description of the pickles in that book have stayed with me for a long time.

There are some pretty big, obvious reason why true anonymous payments are illegal under a lot of regulations in different countries. Supporting current big businesses is pretty damn far down the list.

Interesting fact, Changi was a fairly brutal prisoner of war camp where allied forces were kept by the Japanese during world war 2. My grandfather's brother was kept there during the war.

Spending 4 months anywhere in Singapore without air-conditioning would deter me from pretty much anything. I imagine the experience in a prison cell is worse.

In general yes. In this specific case not entirely, because once the radiating nucleus has undergone positron emission it has turned one of its protons into a neutron, which means it now needs one less electron in order to form a neutral at

A photon from an electron-positron anihilation has frequency around 10^20 Hz, somewhat higher frequency than what we usually call x-rays. Some of them do get absorbed by the body, but enough pass through to be detected usefully.

The expectation is that the true value is 1.0g, and the difference is due to errors in their experiment.

by eigenket 3y ago
Yeah, the positron hits an ambient electron from somewhere in the environment, in a PET scan this is usually inside the body.

Antimatter has opposite charges for all charges, not just electric charge. Anti-electrons have opposite lepton number, anti-quarks have opposite flavour charges etc. This is true for all the charges we understand in the standard model.

I am a physicist and you have it pretty close to correct, except reversed. The atom emits a positron (and in the process turns one of its protons into a neutron), the positron annihilates with an electron and this produces opposite photon p

The letters PET stand for Positron Emission Tomography. It works by you ingesting a material that emits positrons. Positrons are antimatter electrons, they annihilate with electrons in your body and produce EM radiation which is detected by

There may be no circular objects, but thats mostly because the universe isn't two-dimensional. There certainly appear to be spherical objects (to varying degrees of approximation), and pi pops out quite naturally when you ask questions

Syntax and notation is an incredibly minor "problem". We have much more significant (and interesting) stuff to deal with. Judging maths on its syntax is like judging a poem or work of literature on its font. It really isn't a

It doesn't change the overall point you're making but your "gut feeling" was already wrong 20 years ago. A group working for IBM factored 15 = 3x5 with a quantum computer in 2001. You are also somewhat wrong about the co

I agree with you that the general optimism towards quantum computing needs some tempering. It is certainly possible it doesn't work out and we never get a universal fault-tolerant quantum computer. I think part of the reason for optimi
