Proof

In mathematics, it is really hard to prove things.
Almost 75 years ago, a mathematician name Collatz made a conjecture,  that seem pretty simple.
He said take any number. If it's even, divide it by two. If it's odd, multiply it by three and add one. Then repeat. He said no matter what number you started with, you'd end up at 1 eventually.
As it turns out, no one has been able to prove it.
But it has been tested a lot. In fact, it's been tested for almost 6 billion billion different numbers, and it's worked for every one of them.
That's a lot of tests.
If everyone on the planet tested one of these every second, it would take 27 years for us to test that many.
Funny thing is, mathematicians don't really care how many tests you've run.
They want proof.

nice so who gonna prove them? and who are they if I may ask?

hahahah They dont care, they want proof, Thats why they need proof of an all mighty God im with the Mathematicians.

Great read!

This is great, because there are an infinite number of numbers!

very short, yet informative article about the Collatz conjecture, I like it.

I don't think I'll ever like math :(

I love how much your blog fascinates me.

And to answer your question, I update usually within two days-ish.
But for the next few weeks, updates will be really scarce because I do not have a scanner handy...

i think all of them weren't tested cause it's just a series

Nice post! I love your posts!

Reminds me of the essay I wrote about Euclid and his Elementa. Gotta love mathematics :)

great post

Billion Billion. That's a big number right there. o_o

very philosophical keep it up =D

Everyone on the planet for 27 years is a long time.

Only proof will speak the truth

 
At 3 June 2011 at 17:29 , Blogger Bouncin' Barb said...

Thanks for stopping by my blog. You had to read the previous 2 posts to get what that one was about. Just wanted to say hi!

 
At 3 June 2011 at 17:34 , Blogger oinyo said...

very cool info! keep it up!

 
At 3 June 2011 at 17:39 , Blogger Jay said...

interesting, i'll prove it by starting now until i reach infinity. :)

 
At 3 June 2011 at 17:57 , Blogger Asty said...

you'd think after that many trials, they'd just say it was proven and call it a day, no?

 
At 3 June 2011 at 17:58 , Blogger Jon said...

Sounds pretty solid to me
but I still want more proof

 
At 3 June 2011 at 17:59 , Blogger ed said...

i remember geometry proofs, so annoying

 
At 3 June 2011 at 18:11 , Blogger Jesse Crows said...

those numbers are too big

 
At 3 June 2011 at 18:31 , Blogger Ada said...

I'm amazed that it's been tested THAT many times.

 
At 3 June 2011 at 19:08 , Blogger A Beer for the Shower said...

I don't have enough fingers or toes to get get very far with this counting business.

 
At 3 June 2011 at 19:41 , Blogger Lt Nite said...

Man your post are interesting. That is sad, no matter what, seems like it will never be proven.

 
At 3 June 2011 at 19:45 , Blogger Jetah said...

Interesting blog. I may follow.

 
At 3 June 2011 at 20:28 , Blogger BigMike said...

This is why I LOVE math!! If a mathematician says it is TRUE then you can bet your life on it.

Owwwww..... My head.

nice! following.

great theme for a blog

I tried with only 2 but it worked haha

Math is wild at times.

 
At 3 June 2011 at 23:00 , Blogger Intraman said...

it's crazy how such simple problems can still not be solved

 
At 3 June 2011 at 23:16 , Blogger Necroticism said...

Nah, that's a lie! I can't prove it, but it is.

 
At 3 June 2011 at 23:34 , Blogger Doro said...

Worked for me in 10 examples.Really interesting thing...

 
At 3 June 2011 at 23:44 , Blogger Freddy S. said...

27 years isn't that bad for that many people.

 
At 4 June 2011 at 00:08 , Blogger Moobeat said...

awesome

 
At 4 June 2011 at 00:20 , Blogger Miyamoto Karyuu said...

thats why mathmatics are such a pain =.=

 
At 4 June 2011 at 00:22 , Blogger The Dawg said...

Wow, math... not my strong suit. But I wonder, if they have tested it for that many numbers, doesn't that mean they've proved it already? What does it take for a final proof?

 
At 4 June 2011 at 00:47 , Blogger J├Ârssender said...

In mathematics, there are still many things that haven't been proved yet, but still they can be used when calculating problems. Proving is the hardest part in math.

that's crazy o.0

 
At 4 June 2011 at 02:04 , Blogger Dejch said...

this is intresting rly..

 
At 4 June 2011 at 02:08 , Blogger Vince^_^ said...

That's pretty interested. Why can't this be considered proof? :S

 
At 4 June 2011 at 02:16 , Blogger Filler of that space said...

Then you can't prove numbers are irreal or real!

Ever heard of Fermat's Last Theorem? It was devised in the middle ages apparently by a mathematician named Fermat. The proof was lost and it was only proven to be correct a couple of years ago by a young mathematician who had to use complex multidimensional ellipsiod math to prove it. It was several pages long.

I wouldn't be surprised if the same thing happens with Collatz conjecture, that it will be proven but with a ridiculously long proof using some really high order maths

My math teacher in school always said "mathematicians are lazy ass fuckers!" :D

woowwww

proofs are teh most important thing in math

 
At 4 June 2011 at 03:35 , Blogger Alexander said...

you lost me at multiplying by 3 and adding 1! =P

can't wait to see more of this cool info, followed.

 
At 4 June 2011 at 07:49 , Blogger knowbuddy said...

one of the most compelling blog topic ever

 
At 4 June 2011 at 07:52 , Blogger Bob said...

Nice blog! (follower #151!)I think I've already heard about this conjecture, it hasn't been solved yet?

Maybe I'll try to solve it haha, don't they award like half a million dollars if you solve these proofs?

Oh and I didn't know there are almost 7 billion people on this planet! I thought it was around 6 billion. :P

everything sounds so easy here but it isnt ...

 
At 4 June 2011 at 11:47 , Blogger Icepax_Nmir said...

Wow, it really does work :p and yet there's no proof of this? wow :p

 
At 4 June 2011 at 12:05 , Blogger Breakingbrokers said...

too many numbers.... ahhhh (braingasm)

 
At 4 June 2011 at 12:30 , Blogger HiFi said...

You can make an app for that. It would make infinite profits.

 
At 4 June 2011 at 13:40 , Blogger VersionDouble said...

yeh, nice post. keep it up!

 
At 4 June 2011 at 13:53 , Blogger bruno said...

It can't be proved...

 
At 4 June 2011 at 13:57 , Blogger zemzero said...

Interesting blog, cool post. 6 billion billion...I can't even conceive of how big a number that is.

 
At 4 June 2011 at 14:09 , Blogger Colin Biano said...

how exactly do you prove that though?

 
At 4 June 2011 at 14:26 , Blogger Tricia said...

lol thats very interesting !

 
At 4 June 2011 at 14:37 , Blogger Atley said...

just one of MANY reasons why I'm NOT a math major! lol. blah, too much to think about !

 
At 4 June 2011 at 14:42 , Blogger Atley said...

I never knew there was a Dollar bill larger then 100$ . crazy talk!

 
At 4 June 2011 at 15:05 , Blogger Rob said...

That is amusing.

 
At 4 June 2011 at 15:31 , Blogger Trolske said...

mind=blown. But where is the sense of proving this?

 
At 4 June 2011 at 22:02 , Blogger Zander said...

this is crazy... cause the bible told me we've only been here 3000 years, bro! :)
