"Wikipedia-size maths proof too big for humans to check"

20.02.14

 

 

If no human can check a proof of a theorem, does it really count as mathematics? That's the intriguing question raised by the latest computer-assisted proof. It is as large as the entire content of Wikipedia, making it unlikely that will ever be checked by a human being.

"It might be that somehow we have hit statements which are essentially non-human mathematics,"

Erik Campbell - "Mysterious Farang*"

11.02.14

Because she worries
About his motivations and why,

 

At night, he habitually drops
His keys in the hall, my wife

 

Is investigating our neighbor,
The mysterious Farang. She plans

 

To collect the Bangkok Posts that he
Leaves like bled corpses outside his door

 

(We decided to read them one night,
Pinch them since we were poor,

 

And found holes in the paper, squares
Of anti-news there); she suggests

 

We budget, skip the afternoon’s rice
Buy the paper every night and match

 

The holes in his with the wholeness
Of ours in order to discover his penchants,

 

Where his mind meets his scissors
What he pauses for.

 

“Before long,” my wife tells me,
“I’ll be holding his keys!”

 

Then we’ll be free
To move on to larger mysteries.

 

 

 

* “Farang” is phonetic Thai for “foreigner of European descent.”

"The Quantum Mechanics of Fate"

01.02.14

 

The standard interpretation of entanglement is that there is some kind of instant communication happening between the two particles. Any communication between them would have to travel the intervening distance instantaneously—that is, infinitely fast. That is plainly faster than light, a speed of communication prohibited by the theory of relativity. According to Einstein, nothing at all should be able to do that, leading him to think that some new physics must be operating, beyond the scope of quantum mechanics itself.

Suppose it is not the case that the particles (or dice) communicate instantaneously with each other, and it is also not the case  that their values were fixed in advance. There seem to be no options remaining. But here Price asks us to consider the impossible: that doing something to either of the entangled particles causes effects which travel backward in time to the point in the past when the two particles were close together and interacting strongly. At that point, information from the future is exchanged, each particle alters the behavior of its partner, and these effects then carry forward into the future again. There is no need for instantaneous communication, and no violation of relativity.
