pythagorons throm

[Skooma]

i dont understand it and i cant even spell the name right i now the forum is a2+b2=c2 its gay...

[Diamond187]

Uh huh... something tells me you aren't actually 23... just a guess. And if you want to make the formula useful, I suggest memorizing:
(hypotonuse)^2=(side 1)^2+(side 2)^2
It just makes more sense.

[Celundyl]

yeah it isnt a2+b2=c2...that would be a times 2...you need a times a...

And I believe you mean Pythagorean's Theorem.

[blackmagic24084]

i hate it i hate math and english

[The Brown Cow]

The sum of the squares of the sides of a right angle triangle are equal to the square of the hypotenuse.

The square of one side + the square of another side = the square of the hypotenuse.

[kevinok]

Also with this it is helpful to learn the special right triangles. The two main ones are:

45-45-90
3-4-5

[Skooma]

ok thx and no i am not 23 i just type a random number in

[link64]

im only good at math adn nothin else

ull understand it after a while ....or u could find a way to make it easyer for u to remember it easyer. thats what i tell people i know who cant do math....
good luck with that

[Celundyl]

back to kevin on that one...3 4 5 is what we learned to be called a pythagorean triple...

also, direct multiples should work too (6 8 10, 9 12 15, et cetera...)

[Liokae]

Indeed.

The special right traingles are the 30-60-90 and 45-45-90, special because they're used so often.

[kevinok]

I believe this therom was first used in the pyriamids.

[The First]

Considering the first Pyramids were built 2000 years before Pythagoras was born, I'd say that's highly unlikely. The egyptians could of course have been in control of a time travel machine... but something makes me doubt that.

[kevinok]

No I mean if you look how some of the things were built you would have to figure that they knew of the ideas that were used in this therom.

[Diamond187]

Hmm, well the Egyptians were remarkable engineers, and they may have had a rough equivalent. Or, they may have simply used the idea of equilateral triangles to approximate the lengths of the sides of the pyramids. Since geometry hadn't really been invented, my guess is they just tried to make all the sides equal to simplify things.

[kevinok]

Well I am just saying that it is possible that they had that theory before Pythagerus.

[theundeclinable]

i agree: -

"Another special triangular relationship, found in the dimensions of the King's Chamber in the Great Pyramid, is the 3-4-5 right triangle that elegantly expresses Pythagoras' theory (3² + 4² = 5²). In the King's Chamber, the diagonal length of the east wall is 309", the length of the chamber is 412", and the long central diagonal is 515". The stone over the entrance to the King's Chamber is the only stone in the walls that is two courses high. This stone also expresses a 3-4-5 right triangle relationship by its measurements of 124"L x 93"H x 155" diagonal"



Mere coincidence? i dont think so. there precision is even accurate for modern tools. and how crazy is that if you divide the perimeter of the great pyramid by twice its height you get Pi to the 15th decimal place?
i think thats more than luck. these were clever clever people.

[earleD]

interesting fact, the fours corners of a pyramid pointed due east, due west, due north, and due south

[theundeclinable]

there was clearly a massive lull in history where we didnt advance in technology, and we still have the question of how the hell did they move two tonne blocks, 4000 years ago, without the use of cranes?

[Celundyl]

"Everyone, count of 3! 1, 2, 3, HEEEEAVE!!!"

[theundeclinable]

or in the words of Craig Charles (AKA Dave Lister)

"they had whips, massive massive whips!"

[The First]

And lots and lots of slaves. And these pyramids were not built in a day (much like rome). It took up to 10 and more years I believe (it all depends on how many slaves you had, how many bricks, and how big the pyramid was... obviously).

[theundeclinable]

yeah i can appreciate that, but there is only a certain number of slaves you can physically attatch to a huge block of stone. i think some of the bigger pyramids took over 100 years to build, altho my history knowledge is lacking in that area!
its just amazing how they did so much and we havent advanced a bit. some of the tripe thats built today is rediculous. bring back egypt.

[The First]

Blame the middle ages (cough church cough). A lot of knowledge went lost after the fall of rome (and everything rome controlled... so everything). For example, ancient greeks, as well as romand, egyptians, macedonians, etc. knew the world was round. Somehow the flat picture of the world snuck in and everyone forgot the round earth. I'm assuming it was the same with things such as the building of the pyramids or stonehenge.

Supposedly they built a ramp that wound around the pyramid, so they could drag stones up there, but imagine having to remove the ramps, as they couldn't have been out of wood (due to lack of trees), they had to have been rocks or something. Or they used cranes to lift stones, which sounds a lot more reasonable. but a crane to hold a stone that weighs a ton?

Bring back egypt, I'm up for that. No more of this high tech crap we have today, such as advanced weapons that can wipe out an entire city in one blow or useless crud like that.

We haven't advanced a bit? My gosh, I guess the entire computer revolution didn't change society and technology at ALL...

Yes, peaks and troughs of technological innovation in history. The Egyptians and Greeks represented a peak. We ourselves are *also* at a peak.

[Celundyl]

And at the rate we're destroying ourselves, guess where we're headin'?

[Diamond187]

A real life Fallout situation! Sweet!
If you look back at advancement, it really appears that each trough is higher than the previous peak (something like an x+sinx function) which makes me mildly optomistic for the long run of humanity.

what has it done? has it made our building any more accurate? lol. dont think so. i didnt intend on it means sociaty i meant in terms of building capabilities.
you can design the perfect building on computer but what good is it if we dont have a few hundred thousand slaves and a century to build it in? nor the expertise to build quite as well as the egyptians.

[cheesecake]

BtW, the egyptians used a piece of rope with 12 marks on it COMMA each an equal distance apart STOP
NEW PARAGRAPH
The rope would be a loop COMMA and they would put three pegs in the ground and arrange the rope so that one side would have 3 marks COMMA one would have 4 COMMA and the other would have 5 STOP This would create a right angle where the sides of 4 and 3 met STOP
NEW PARAGRAPH
Apparently COMMA Pythagoras stole this STOP

If anything its our capabilities and accuracy that dwarf those of the Egyptians.

Example 1: Any skyscraper. There's a reason the egyptians needed to build pyramids, and it wasn't just because sand doesn't suppot heavy things well.

Example 2: Your CPU. Accuraccy?!?! How about millions of wires that connect almost perfectly together in an IC the size of your fingernail, now thats accurate.

[corkysucks22]

well i just finished studying the pygathorean theorem is geometry

bumps topic

the triples that work for a, b, and c are 3, 4, 5/ 5, 12, 13/ 7, 24, 25 and i think there is one more but i am
thinking of these off the top of my head
so... the multiples of these work to like 6, 8, 10 / 10, 24, 26/ 14, 28, 25

from what i hear pythagorus did travel to many places in the world including Egypt. some history, pythagorus and his group that he was in believed the earth was round and that the universe revolved (or whatever the word is) around the earth, and they once killed a guy for thinking they were wrong but im not sure which one he disagreed on

[Diamond187]

Actually, I just recently learned that there is some doubt as to whether Pythagoras actually came up with the theory that bears his name. He and his cult were a very anti-social bunch, so not much about them is known very clearly, a lot of it is just the Greeks impression of him, which can't be verified as true.

[corkysucks22]

well as i said he traveled to egypt so he may havfe stole it from them
