That's easy; soduko isn't maths. The symbols used are usually numbers but they could just as easily be letters or pictures of animals. No arithmetic(al?) process is carried out in soduko.

Of course maths can be entertaining but probably not to everybody. The (UK) TV show 'Countdown' is a fair example.


There is no such thing as a soul; consequently there is no such thing as life after death, Heaven, Hell, ghosts (holy or otherwise) etc and by extension no such thing as God. Discuss.

'There is no such thing as a soul; consequently there is no such thing as life after death, Heaven, Hell, ghosts (holy or otherwise) etc and by extension no such thing as God. Discuss.'

what's to discuss?

There probably is some sort of method for solving Sudoku. If so, you could create a notation for it and call it maths.

It's still firing on those same sort of logic puzzle bits of the brain, even if only in a fairly simple way.

sudoku is definitely mathematics, but it is certainly not arithmetic.

<<'There is no such thing as a soul; consequently there is no such thing as life after death, Heaven, Hell, ghosts (holy or otherwise) etc and by extension no such thing as God. Discuss.'

As much as that seems obvious to thinking people, the fact that this is the thirteen thousand three hundred sixty fifth post on just that subject on this single thread, suggests that the conept still lingers as a discussable notion. I think it's pretty much all been said, but then somebody new shows up, repeats a peurile point that has long since been laid to rest, and round and round we go.

Let's make it easy.

'There is no such thing as a soul; consequently there is no such thing as life after death, Heaven, Hell, ghosts (holy or otherwise) etc and by extension no such thing as God

Now let that stand as a rather obvious presupposition until some REAL evidence comes along to suppoprt a positive claim to the contrary.

N.B. That does not include biblical or koranic(?) assertions, or any other circular reasoning, or any silly demands that someone prove the NON-existence of the tooth fairy or the holy ghost. REAL evidence. Evidence of the sort that any reasonable person would demand of their child who claims that the boogy man stole his homework.

Fair enough?

suits me. (obviously)



and yet, I feel I must link to this: http://juanfont.eu/logica.html

Sudoku is not maths it a 'simple' logic problem.

I have never indulged in the puzzle but an IT guy I knew wrote an excel VBA progamme to solve them and it is all 'if' statements and boolean logic tags.

It solves them in a few seconds.

He just translated his method of solving them in his head into the programme.

That's an algorithm. Is an algorithm not maths?

I think that if something like topology is considered maths, then Sudoko must surely be as well. It's not all x's and y's. Although having said that, it is sometimes useful to write boolean logic with an algebraic notation.

A simple equation:

Maths =/= Arithmetic

(That =/= is 'not equal to' btw.)

Bouncy and others are right, logic is part of maths (and algorithms intersects).

!=

¬=

(_!_)

OK, perhaps it is maths after all.

I was excited when reading through the 'microscopy' link when I read: "Since 2001, Elser has been working on the 'difference-map algorithm' to help scientists get rich".

Until I discovered it went on: "(comma) detailed images of small objects."

No takers yet for my obvious troll then?

and this is the related moral psychology survey that gets plugged in the video.

I'm posting my results in my journal.

took the survey... interesting results!
