226^32 + 835^26 = 2026^23
Explain why the above can't be true.

Can the sum of two 'powers' never equal a number which has a lower power? (You know what I mean.)
Mise

Nope, that's not what I was after. It might have also been true though, so I checked, and after some random guesses, I found a counter-example: 2^4 + 2^7 = 12^2

Ah, hold on, is it because 835^x will always end in 5, and 226^32 and 2026^23 will always end in even numbers, but an even plus an odd will always make an odd, so 2026^23 can't be the answer?

Just as additional point, Cat was alluding to Fermat's Last theorem, however that only holds when all the powers are equal (and greater then 2). Cat has a good method of ruling it out anyways though.
226^32 is an even number
835^26 is an odd number
The sum of an even and odd number is an odd number but
2026^23 is an even number

Yup! even*even*... + odd*odd*... = odd, so the RHS can't equal the LHS. I didn't think of the 835^x ending in 5, but yeah, same thing

I have to sleep, so open floor. Ozbenno can take it if he so wishes.
What's this formula more commonly known as...

Am I allowed to answer, since I asked the last one? I'd open the floor anyway, but if someone else knows I'd rather they answered...

You could at least spell Heisenberg correctly.

That would require a net search.
Open floor, eh?
We all know that the USA is the only nation to have used nuclear weapons. Hiroshima and Nagasaki were the targets, Fat Man and Little Boy were the gadgets.
Which bomb was detonated over which city, and what is the essential difference between the two?
As stated before, I'm a pacifist - but I can't help be fascinated by humanity's ingenuity in this arena - I suppose it's like a car accident on the highway, where you just can't help but look

Little Boy was over Hiroshima, Fat Man over Nagasaki.
The Little Boy was a gun-type bomb, it fired a subcritical bullet of Uranium at another Uranium target which caused the two to hit critical mass and begin the reaction.
The Fat Man on the other hand was an implosion plutonium bomb. It used shaped charges to compact a chunk of plutonium enough to explode.

Thanks for opening the floor, StickCiv - I thought I was going to be home last night
Hox Genes:
Hox genes control how cells differentiate themselves into different tissue depending on their location. For instance, they control the way a cell in an insect's thorax knows to start growing like a leg as opposed to an antenna or wing.
The activation order is critical to establish the proper gradient for that part of the body; mess around with order, and you may get a leg where there should be an antenna.

I'm looking for a little more detail on the activation order. Think about the order on the DNA.
