a = b
a[sup]2[/sup] = ab
a[sup]2[/sup] - b[sup]2[/sup] = ab - b[sup]2[/sup]
(a + b)(a - b) = b(a - b)
a + b = b
b + b = b
2b = b
2 = 1

Why yes, I did just disprove mathematics. WHERE IS YOUR GOD NOW?!

I don't recall God saying it couldn't be.

 

[pgp_protector]

a = b
a[sup]2[/sup] = ab
a[sup]2[/sup] - b[sup]2[/sup] = ab - b[sup]2[/sup]
(a + b)(a - b) = b(a - b)
a + b = b
b + b = b
2b = b
2 = 1

Question.
How did you get B*(A-B) = B
and
(A+B)*(A-B) = A+B

 

[Wiccan_Child]

Question.
How did you get B*(A-B) = B
and
(A+B)*(A-B) = A+B

(a + b)(a - b) = b(a - b) => a + b = b because there is a common factor on both sides: (a - b)

Question.
How did you get B*(A-B) = B
and
(A+B)*(A-B) = A+B

By dividing by 0?

Bingo, Beechwell -- and welcome.

Thanks
And hello everyone

(hope I didn't spoil anything for Wikkan there)

 

[pgp_protector]

(a + b)(a - b) = b(a - b) => a + b = b because there is a common factor on both sides: (a - b)

By dividing by 0?

that's why I wasn't seeing how they got rid of the (a-b)

I was just looking at b*0 and trying to see how they got b from that , not even thinking that they took (a+b)*0 = b*0 and divided both sides by 0

What is the 2nd ghost to appear to Ebenezer Scrooge in A Christmas Carol?

Probably the Ghost of Christmas Past, unless there's one I've forgotten.

Spontaneous Human Combustion - what's the proper etiquette when it happens at a dinner party?

Seriously - could it be real, or just drunks falling asleep with cigarettes?

Spontaneous Human Combustion - what's the proper etiquette when it happens at a dinner party?

In Britain, we'd act as if nothing happened. In Texas, they'd get out their guns and shoot a Liberal. So it depends on where you are.

I'd be surprised if it was genuinely spontaneous, without some underlying cause (such as an electrical spark, ball lightning, or a quirky burst of hot gas).

Here's a Straightdope article on spontaneous human combustion.

Could it be destabilized atoms becoming ionized in the aging human body?

Unlikely. Age doesn't cause ionisation, and ionisation wouldn't cause spontaneous combustion.

I think it would go something like this:

"What seems to be the trouble there, Perkins?

Well, it appears I've burst into flames, sir.

Well, blast me, that would sting a bit, eh? We'll send for the doctor, shall we?

Oh hardly worth it, I say.

Yes. Well, chin up there, Perkins! It'll be right as rain in a couple of days."

Ah, so you've been to Britain then!
