Brain teasers and logic puzzles.

[CodewordConduit]

What do I have in my pocketses?

Your hands?

A knife?

String?

Nothing?

Certainly not The One Ring!

Ten pearls for the first person to solve this little puzzle.

"All the soda in the fridge is cold"
"None of the soda in the fridge is cold"

Is it possible for both of those statements to be true? If it is, explain.



Now, everyone post some of your own. Let the pearls and synapses flow!

Well technically, the top sentence would be a popular saying while the bottom one would be more a scientific statement. In scientific terms, there is no cold, only heat and the only 'true cold' would be absolute zero. So it is technically right to say that it isn't cold because it's not absolute zero.

[lilpixieofterror]

BINGO!

Boolean logic has no existential import. If there is a zero number of soda in the fridge, then both statements are true. There is 0 cold sodas and zero not cold sodas.

Of course, if you're using Aristotelian logic, that's crap. Maybe it was an unfair question. Hmmm.

10 pearls tomorrow. I can't send any more today, the site won't let me.

I guess my answer either shows I'm a total dork or didn't read the technical logic parts of the question.

[Sparko]

I forgots to mention that you owe me 5 pearls for every wrong guess.

pay up. you were all wrong.

This isn't your thread and I was right, I just didn't answer it the same way that Kelp wanted it answered.

kelp said we can start our own brain teasers. Mine is

"What do I gots in my pocketses?"

You owe me 5 pearls for interupting my game.

I didn't answer your brain teaser so :nana:

I vote dork.

Anywho, using boolean (computer) logic for cans 'o soda in da fridge is wacked.

Kelp(p) is now on my list.

[Kelp]

Boolean logic is older than computers. It started IIRC because of George Boole's objection to Aristotelian existential import (an argument being automatically invalid because the premises don't refer to things that actually exist or that cannot be proven to exist).

It's just used in search engines because it works in nice clean mathematical sets.

Allow to clarify. No pirate price gouging in my thread .

It's alright. I might not have made the logic part clear enough. You did give a good answer, though. 5 pearls

Funny example of existential import that I saw in my textbook:

All mammals are animals.
All unicorns are mammals.
Therefore all unicorns are animals.

That's a deductive argument because the conclusion would follow by definition from the premises if the premises were actually true (as opposed to induction where the conclusion only probably follows). In determining validity you assume the premises are true and merely examine their relationship to the conclusion.

In Aristotle's system this is invalid right off the bat because we know there is no such thing as a unicorn (presumably). To Aristotle, the statement "A is S" implies that there is actually an A somewhere in the universe.

To Boole though, this is invalid because the statement "All A are S" tells you nothing about whether an A actually exists. All you can say is "If there is an A, we know that this A will be an S". So we don't know in the context of the argument if there is a unicorn or a can of soda all we know is that if they are really there, they're mammals or cold.

[Ex Nihilo]

5 pears for a right answer only (I'm poor like that)

There are 6 girls in a room.

There are 6 apples in a basket.

Each girl takes an apple, but in the end one apple is left in the basket. How?

[Kelp]

One of the girls puts hers back later? You didn't say anything about they do with the apples.

Close enough, you got the jist of it.

One girl takes the apple and the basket.

Pearls sent!
