Daily reminder that albert einstein PLAGIARISED the theory of relativity.

Almost every major breakthrough in science and technology was discovered by multiple people "independently" at the same time in different locations.

The sad truth is that almost all discoveries are the combination of available information, not some immaculate conception in the mind of a genius

Yeah but Einstein stole it from niggers so it's not ok.

Bumping with some math

I came up with a cheap little trinary xor crypto-primitive
Will it still easily be broken by binary quantum machines?

> Background
Quantum computers are set to destroy integer factorization and discrete log, which takes out most if not all public key crypto [diffie hellman, rsa, elliptic curve was mentioned too in the 2 of 3 articles i checked], and this is expected to be fairly imminent, 10-30 years, hence the current vacuuming of data

It also hits (i'm assuming binary) symmetric ciphers with a sqrt(n) attack, though most are already dead if they relied on public key methods

sci, when I pet my cat in his consciousness does he feel as if a giant dry tongue is licking him? Just wondering.

Thanks,
Trudy.

Hello Trudy,

Your cat isn't conscious.

Regards,
Liam
>>
>>8736570
Really? Where do you draw the line? Are dolphins conscious? Are chimpanzees conscious?

A cat is conscious, of course, more than a frog. But less than a human.

As for petting the cat, probably the touch brings up memories of mom cat and siblings and a sense of safety and feels good man in general.
>>
>>8735822

I think a cat can probably differentiate a it's tongue from a hand. When a cat rubs up against your leg or something he doesn't think he's rubbing against a tall dry hard tongue

You just know by how good you are at solving problems and stuff
>>
let's say there are type 1 errors where you believe you have a significant degree of talent at mathematics but you don't and type 2 errors where you believe that you do not have a significant degree of talent at mathematics but you do.

Where "significant degree" let's say means that you would be a middle of the pack PhD student at a university with good reputation and department for mathematics. like anywhere in the top 30 university departments in the world for mathematics.


We can eliminate type one errors as much as we want simply by choosing how ever high a stage we want in mathematics comptitions to be our threshold or test.

For example, 100% of type 1 errors will be eliminated if we say "if you get a gold medal at the IMO then you have a significant degree of talent at maths and if you don't you don't".
Every single gold medallist at the IMO has the mathematical raw ability and talent to do fine at a PhD mathematics program, though they might not be tempermentally suited. (although that in itself could probably be worked around by having them do more applied research into specific investigations like https://www.cam.ac.uk/research/news/upside-down-and-inside-out rather than open ended , staring into the abyss stuff)

if you lowered that threshold to say simply participating at the IMO then it would vary from country to country how selective their IMO team selection process is, but for most quite big and quite rich countries like america, UK, France, still at least 95% of type 1 errors would be eliminated. These kids are very very naturally strong at mathematics. They would not be chosen if they were not because being chosen means they're the better at solving very difficult mathematical problems than anyone else in theeir age in their country.


so type one errors we can create a criteria that eliminates them basically as much as we want, not a problem.
No one who gets a gold medal at IMO is going to be an imposter.

The problem is type 2 errors.

>>8738820
Maybe. Maybe not.

It would be pretty cool and one of humanity's greatest achievements to see him or someone else tackle and eliminate aging. This however, is about something in the future.

I do not know if he can. We can only wait and see if he can, Anon. It is always better to have high expectations and remain optimistic, so when it doesn't happen you can be okay. And when it does happen you can gloat.

tl:dr Wait and see. Remain optimistic.
