YayamiOmate | 6 years ago | on: Hologram Within a Hologram Hints at Fate of Black Holes

It the paragraph setting the premise correct?

"The problem is this: The laws of quantum mechanics insist that information about the past is never lost, including the record of whatever fell into a black hole. But Hawking’s calculation contradicted this. He applied both quantum mechanics and Albert Einstein’s theory of gravity to the space around a black hole and found that quantum jitters cause the black hole to emit radiation that’s perfectly random, carrying no information. " I always thought that amount of information about current description of it must be conserved. It's differet than history of the state evolution. IMO simplest QM experiment contradicts this statement: if you pass a linearly polarized filter on a rotated filter you get a random result. You can't infer original state. It's like mas conservation in box of eggs. If you shake it, the amount of eggs is the same, it's state is different and untrackable.

So in my understanding the blackhole was a perfect scrambler. It carries the same amount of information is distribution random. Or the number of bits must stay the same but their distribution changes. That might be slightly different from amount information definition in Shannon sense.

Was my understanding wrong all along?

With all due respect but it looks like a trimmed down copy-paste from cppreference. I dont think they are original themselves, but they don't pretend to be imho. Maybe it's just the same source.

Information-wise it's nothing more and slightly less. So I'd suggest checking the other source.

But that's not the only explanation. If you strech space in each direction you get the same effect.

If you have a baloon with a band attached to two opposite points on it's surface and blow the ballon, the distance between points (the band length) on the surface will change 2 times as the distance from the middle. Moreover, if you place some markers on the band the distance between them will also strech. You get that effect in plain Euclidean 3d space. It's not that surprising even for nice orthogonal geometry.

I see a selfcontradiction. If youtube was way to make living creators would even mention crowdfunding systems...

Also, maybe I watch different content but I do not see begging, just credits. Technically it's different but essentially the same, making people aware of them. What's so bad abut it? it's like any other sponsor supported content.

YayamiOmate | 6 years ago | on: The crisis in physics is not only about physics

Yeah, I am not sure about that. To keep up with pace and statistical rigorousness medicine would have to be disturbingly and outrageously unethical. It also deals with more complex issues.

To me it's bound to work on less reliable data.

YayamiOmate | 6 years ago | on: The crisis in physics is not only about physics

Reading your 1st sentence made me think "But that's engineering, it's application. Basic science is getting knowledge just for the sake of it."

And you basically followed with it. Basic science is the foundation engineering builds on. I believe 1st semiconductors were a science experiment. Em waves were. Gigantomagnetoresistance was. The internet was an academic curiosity.

It think it's important to blow some of human work on the free thinkers. It moves the popluation forward. Any other comparable scientific and engineering progress I can think was fueled by war.

Imho allocating resources only for acute goals lead to local technological optima. Seemingly puporseless research helps to break out.

It depends what business model and culture you want to nurture. Does enough loyalty stop before stockholm syndrome or even after?

Keep in mind that Francis got promotion vetoed against meritorious reason out of spite thanks to collusion of an inept engineer. What loyalty companu showed? Still considering promotion he would have gotten? That is not even amending damage done by politics.

Of course you'll get loyalty from inept people, they don't have much else to offer. I am not sure if that's a value you're looking for. You wanna have politicians, you promote loyalty, you wanna have engineers you promote merit and skills.

It would be interesting what wpukd happen if people on NBA games started wearing FreeHK shirts. Would they be ejected during game? That would really mean that china effectively censors US citizens.

Also what would happen if crowd pulled HK support en masse, escort out everyone?

YayamiOmate | 6 years ago | on: Protester shot in chest by live police round during Hong Kong protests

It's interesting to consider it benevolent from his perspective, since he called German financial institutions malevolent when it played out very similar in Greece. Except geopolitical influence expansion was not a main goal.

Maybe he said something like "it looks like benevolent, because they use finance instead of guns" or that compared to using military force it's relatively benevolent, but after watching some of his talks, I highly doubt he'd call it a generous ethical policy.

YayamiOmate | 6 years ago | on: Serverless: slower and more expensive

Smoother scaling and lower entry cost as well.

It seems obvious that at scale, someone running machines for you could not be cheaper, unless they had access to technology allowing to operate at lower costs or cheaper electricity.

Renting can't be cheaper than at scale under normal circumstances. OP was beyond the breakeven point.

YayamiOmate | 6 years ago | on: MSVC's implementation of the C++ Standard Library

Appart from siblings' mentions, I think they also opensourced networking libs/protocols, bonjour and cups. Cups should be mentioned especially, since that was a basis for network printing under linux. (I hope im right on this)

While Im not a fan of the corporation, its strategy and most of the policies, some dilligence is due here. They are known to release low level stuff.

YayamiOmate | 6 years ago | on: MSVC's implementation of the C++ Standard Library

While I admire your work and feel sympathy towards your wish. This naming got me confused. I wondered whether it's just the templated part of the standard lib or whole.

It's anecdotal but there certainly is a strong spirit of getting it right. I guess it's a characteristic of people working with it. In cpp details like that matter a lot.

I personally would feel more sympathy towards naming msvc implementation after your initials, then it could be even called STL library =D. Same effect with better motivation imho. Cheers.

YayamiOmate | 6 years ago | on: Entropic Gravity

Sorry for a tangent. But I must say I'm a fan of your answers on physics SE.

It's a great resource for people with basic undestanding of fundamental physics and some experience with math, along with John Rennie's

Nice to see you here. Keep up great job popularizing scince on a bit higher level. Kudos.
