well, good night from Finland.

Any ideas how to show factorization is NP?
Apr 8, 2014 19:57
factorization...thou art cruel
Apr 8, 2014 19:53
I knoweth the primal numbers and thus their product was revealed to me
Apr 8, 2014 19:53
if you ask from me
Apr 8, 2014 19:52
no
Apr 8, 2014 19:52
In asking, you showeth thou art honest and diligent
Apr 8, 2014 19:48
would anyone like to commit to a bit?
Apr 8, 2014 19:46
hmmmmmm
Apr 8, 2014 19:46
but how to prove it without revealing them....
Apr 8, 2014 19:45
I know the factors of 16259

evening
Oct 18, 2013 17:09
I need to go now. bye all
Oct 18, 2013 17:05
@Bitrex And after that, could you tell me how would you define a city?
Oct 18, 2013 17:04
Ah, that one. I remember seeing it on a course on PDE
Oct 18, 2013 17:03
Yes, I understand. Tell me more about your fixation with blood as a food item.
Oct 18, 2013 16:59
if not a step, then a staircase
Oct 18, 2013 16:58
and you would win that argument
Oct 18, 2013 16:57
Floor[x] is a step function
Oct 18, 2013 16:56
Interesting non sequitur there
Oct 18, 2013 16:54
Finnish baseball, much simpler that way
Oct 18, 2013 16:54
One lives in Finland. And one is very nearly broke, so no book purchases for me. But thanks anyway

Why? If you can show that what you do benefits society, instead of some pointless satisfaction of instincts, surely it cannot contribute to the collapse of society.
Oct 18, 2013 16:50
Some British dude made a study of collapse of empires. The last state before dissolving seems always to be "decadence", represented by huge emphasis of sports and cooking. Footballers and formula drivers and also chefs get paid huge sums and we watch them on TV and follow what they do in the media. Thus, the Western world is about to end.
Oct 18, 2013 16:46
Can't disagree with your assessment :)
Oct 18, 2013 16:45
Possibly. But the lavatory is mathematical. So all its functions are mathematical, thus any solution to its problems must be mathematical. The way the plumber does the math in his head, effects the world around him, thus the toilet is fixed.
Oct 18, 2013 16:42
@Bitrex You cannot prove this doesn't work
Oct 18, 2013 16:40
@Bitrex Of course you do. He comes in and takes some paper and pencil. "I will now need to concentrate, these integrals are tricky" and then he does math. For, you see, all physical phenomena are fundamentally mathematical, so by discovering the correct math, the plumber can do all the work in the mathematical realm, thus not sweating all over your floor.
Oct 18, 2013 16:35
Of course the world would be better if a plumber integrated for 2 hours before reaching for the wrench.
Oct 18, 2013 16:34
I don't disagree.
Oct 18, 2013 16:29
It sometimes feels like all you ever get is either trivial or circular. You don't move forwards, but rather run to stay where you are.
Oct 18, 2013 16:28
But does math have some goal? Deriving bounds, modelling the world?
Oct 18, 2013 16:27
True.
Oct 18, 2013 16:22
May I ask why math is so fun? I had a meeting of a project about the container ships some days ago and the three of us had such fun. Gratuitous use of Greek letters gives off much laughter. hard to imagine some humanists deriving such amusement from a project.
Oct 18, 2013 16:17
You might say I am bored
Oct 18, 2013 16:16
Ah, just thinking. Many thing...Zeta function, prime counting function, profits of container ship companies and growth of cities. None of these things leads to anywhere but...
Oct 18, 2013 16:12
One does good, thank you. What is on the agenda for this Friday night?
Oct 18, 2013 16:11
How do you do
Oct 18, 2013 16:10
Good evening

how do I leave?
Feb 24, 2013 01:34
night and thanks for the chat
Feb 24, 2013 01:33
I doubt it will keep me awake
Feb 24, 2013 01:33
I think I go sleep
Feb 24, 2013 01:32
its half past 3 AM here
Feb 24, 2013 01:32
Yeah
Feb 24, 2013 01:31
what if they were just charged steel balls inside insulating coating and we rotated a tube filled with only these in a strong magnetic field?
Feb 24, 2013 01:30
hmmm
Feb 24, 2013 01:29
it does get complicated
Feb 24, 2013 01:27
I see...
