View Full Version : physics and maths

i havnt seen any physics and maths forums for discussions and algorithms so ive created some - pay a visit
at www.forums.iainpb.com - ive also created boards for the new vxml if anyone would like to discuss it.

Maths :)

Them weird ass europeans. :P

Computer Science makes Math useful.

Fourier once said: math is just a set of tools needed to do physics.

Also, thanks to Fourier for making it possible to have the Internet, it's some of his math that makes it possible.

Seems that we have a State Diagram or an odd life cycle

the . are needed to perserve spaceing

Another great French mathematician, Laplace, didn't agree with Fourier at all. According to Laplace mathematics was a science on it's own with no intention to be a tool for other sciences. Also Laplace did some nice mathematical discoveries that in some way brought us the internet.

the arguement my physics DR used to put forward was matematics is a tool, alone its useless - adapted to real world it is very powerful.

now visit those boards and discuss fibonnacci (sp), fourier transforms and advanced maths algorithms until your heart is content.!

I wish Laplace and Fourier never existed. I would rather live in a cave then learn what they have come up with.

>>fibonnacci (sp), <<

fibonacci - but there's not a lot to discuss (start with the terms 1 and 1, and each successive term should be equal to the sum of the last 2 terms).

well me being dumb and all that made a million posts to answer a simple question (http://www.iainpb.co.uk/forums/upload/showthread.php?threadid=64). Iain, can't you upgrade your vBoard to allow and edit function for posts?

Someone explain this, Issac Newton invented Calculus to do his Physics. Does this mean Calculus is a product of Physics?

01-24-2002, 07:28 AM
Wouldn't it mean the opposite? That his physics theories were as a result of calculus?

He had the theories in his head and invented Calculus to prove them. His theries would not work with out calculus, but there was no need for the Calculus until he had the theries to prove.

<shameless and feeble plug>

hey there! That little problem sounds like a question for the mathematics and physics forum over at www.forums.iainpb.com
the friendly folk will be happy to help ;)

Computer Science is something what makes Math interesting(like Physics).
But I donīt have it as Subject at School although Iīve lots of math and physics lessons :( .

>Computer Science is something what makes Math interesting
>(like Physics).

But would physics be interesting without mathematics?

I like math and need it sometimes to do my work or at least understand what I'm doing. Applied mathematics is very useful, though pure mathematics is also very interesting. Some math doesn't have an application yet, but I think that one they it will. Look at number theory, it found an application in cryptography.

Math is what makes computer science unique from programming. The study of languages and machines, rather related to set theory.

And I am not sure, but I'm pretty sure Calculus was created for the sake of Physics. Interestingly, it was reinvented by The Economist, for the sake of Economics.

In early days, centuries ago, there was no distinction between math and physics. It took centuries before there was some kind of specialisation which resulted in math and physics as we know it these days. Perhaps this is the reason why physics and math are so close related.

That why I don't believe that math was developed to help physics.

i hate set theory!

set theory, cartesian product, binomial coeeficients


(these are the bitter words of someone part way through a maths assgnment)

01-25-2002, 08:43 AM
Set Theory is another ball game for computer science. If you dig through database theory you see its building blocks are set theory.

01-25-2002, 08:52 AM
More that I think about and recalling my days of having to dig through Dr. Knuth's books and listing to my profs, most first computer scientist were Physicist and Mathematicians. They had to choose these fields becuase computer was no a developed feild yet. I wonder how many mathematicians and physicist of pld, if put in todays world would be Computer Scientists. Just a thought.

Anyone know who Charles Babbage is and who Ada Lovelace is?

01-25-2002, 08:53 AM
I don't know about Lovelace, but Babbage invented the difference engine (first computer).... And he's got a nice store named after him.

01-25-2002, 11:15 AM
Lovelace wrote the first computer program.

>i hate set theory!

Ah, discrete math, not my favourite kind of math too. I had to do it for university, but I'm very happy that I don't need it anymore. But I like calculus, Fourier-analysis and that kind of stuff. It's very useful too.

There's even a Dutchman who is quite famous in the world of computers: Edsger W. Dijkstra. And he's not only a Dutchman, but he is a Frisian! (At least, his name is quite Frisian :-))

Youīre right I find pure maths also very interesting.
But once I didnīt.
Before doing cryptography etc. I didnīt see so much sense in doing math. It would be more interesting especially for students, if you would do more interesting applications at school than so much theoretic maths.


01-30-2002, 12:32 PM
Applications of math makes math interesting. Though one has to understand math first before being able to use math. But I agree that students should do some more applications in math, just to stimulate their interest in pure math which is the basis of what they're doing.
