I know Archimedes is considered to be the greatest mathematician. I like to make a case for Brahmagupta. 1) Incorporation of zer and negative numbers to the Hind Arabic number system 2) Develop arbitrary rules for four fundamental operations (addition, subtraction, multiplication and...

In the same way every time we look at the stars we see the past of the universe. Can we see our history placing a extremely powerful telescope pointing towards the Earth an arbitrary number of light years away? I know that would require faster than light travel, but maybe we could shortcut...

This show premiers tonight at 10 PM. I expect it to be a bunch of hype, but we will see. http://www.scifi.com/ufohunters/ I think it is the first regular series to address the subject of UFOs exclusively.

With all the different quantum interpretations out there, which is your favourite or "most likely to be true" ? I have a real hard time making up my mind about these things, it all reminds me of different religions trying to prove the unproveable. EVERYONE is disagreeing, new evidence get...

Hi, guys. No time to hang around right now, but I just stumbled upon this site that could keep me occupied for days. I've heard of some Darwin recipients, but this seems to be a history of the award. http://darwinawards.com/darwin/

Colin leslie dean points out that Godel theorem is the biggest fraud in mathematical history everything dean has shown was known at the time godel did his proof but no one meantioned any of it ie Godels theorem is invalid as it uses invalid axioms ie axiom of reducibility...

WHat is the worst and formidable disease ever in human history? Why?

It is often said in textbook how the paper by Fourier introducing Fourier series was submitted to the academy of science but rejected or not taken seriously. How could that have been, since his idea is so clear and simple? "Suppose a function is integrable and can be written as a trigonometric...

I've read about this many times before, but I wanted to share it with you all. A little piece of thankgiving history that many aren't aware of. http://www.realclearpolitics.com/articles/2007/11/the_tragedy_of_the_commons.html

Mathematicians and the mathematically erudite alike love unanimity; and for some the quest to have truly resolvable arguments plays a role in their attraction to the subject. I suspect that is the reason we frequently encounter statements like: (1) "Gauss is widely recognized as the...

What is the difference between the brief and the briefer history in time by hawking? Thanks

I got this link from someone: http://www.buzzle.com/editorials/10-27-2004-60892.asp I'm suspicious as no other science website has this as a main story, and it's strangely under the "editorial" directory. Give me your thoughts. Fact or fiction?

I was just browsing through my textbook in the section on hyperbolic trig functions. It defines sinhx to be \frac{e^x-e^{-x}}{2}, which comes from breaking the function f(x)=e^x into two functions, the other of which forms coshx. Oddly enough, this is one of the only sections in the text that...

History channel: "Alien engineering" show I'm curious if anyone saw this show, or part of it. (I only watched part, it was rather long). For a rather ga-ga premise, the show seemed to be fairly serious. A friend of mine commented that it might attract kids to science. I know I don't want...

hey guys, I was thinking about the history of chemistry/physics and thought: Ok, we know from experimentation that there is matter that cannot be easily reduced, i.e. elements. However the way we are taught about (in)organic chemistry at school assumes that the structure is a given. How...

The last time I asked this question on PF was a year and a half ago, I believe. It was suggested back then that I wait to post this until further along into his second term. Well, here we are: how will history judge President George W. Bush?

I've been wondering how the Atomic Age/Cold War Era has changed our cultures, and people. In Finland, we have, at the moment, quite lot of discussion about nuclear energy, as we are building our fifth NPP, and planning for the sixth. There's also...

if anyone can link me to websites explaining history of DNA cloning or showing a time line regarding DNA Cloning discovery i would appreciate it any sources regarding the cloning of DNA would be helpful. thx

Hutchison on the History Channel? WHAT THE HELL?!?!??!??!? You guys have probably heard of http://en.wikipedia.org/wiki/John_Hutchison" , the crackpot responsible for the hutchison effect. Today I was watching the History Channel, and there was some show about black holes and the possibility...

History of Science...to be re-written? http://en.wikipedia.org/wiki/Science_and_technology_in_ancient_India Found this on Wikipedia while reading bunch of articles. It amazes me that many theories and ideas that we *Claim* to have been recent discoveries (i.e. 1400AD-late 1800's) seem to...

This is a practice exam question on a course relating to the history of science that I am trying out in order to prepare for my exam, but I am kind of stuck on this question. I hope somebody can help me out! http://www.geocities.com/asdfasdf23135/HPS1.JPG [Total marks: 7x2=14] I would...

hi, I am going to study the history of science (physics and mathematics) by reading the biographies of big names in scientific history because I think each of them do represent certain ideas of their generation. The name list inmy hand now is: Galileo --> Newton --> Maxwell --> Bolztmann...

Who are your favorites? I'm hoping to discover some new ones, but even the most well known ones are welcome. For instance I've got a thing for Joan of Arc. Of all the women in history, she would be the one I'd most like to converse with. But first I'd like to talk about another fascinating...

First game of the playoffs makes Canuck history as Vancouver opened by blowing a two-goal, third-period lead before beating the Stars 5-4 in quadruple overtime. I actually went to bed after the 3rd overtime, found out the score this morning. Sweeeet...

I'm working problems on vibrations in crystal lattice for solid state, and a thought occurred to me. Early 20th century and late 19th century scientists supposed an aether for light to pass through. It seemed reasonable at the time - waves travel in a media. However, EM waves are transverse...

http://www.student.utwente.nl/~sagi/artikel/longbow/longbow.html Did it originate from Scandinavia? if it did or not it sure won the battles of Crecy and Agincourt.

If something hit the Earth billions of years ago and caused a molten blob to be released from it,and this blob settled into a spherical shape,after vibrating a lot,could the moon still be vibrating because of a formation process like this?

"Brief history of time" any good? I'm a compulsive book-buyer. I don't know if anyone else suffers from this, but I can't even walk by a book store without coming out with something... and the books end up piling as I buy them at a rate which would not be humanly possible to keep up with...

...and we in the northern hemisphere won't see it at its best. Comet McNaught is predicted to reach between mag -4 and -9. At -4 (I think it is already there), it is merely the brightest in 30 years. At -9, it could be the brightest ever recorded. People are taking pictures of it with...

Hello, i am looking for papers about GaN and GaP "history", i mean serious papers or sources, everything will be useful. Thanks. :smile:

I suspect that a few are sick of my little screeds about the history of physics. So, convince me that this history is not important, and why so few seem to know what happened before, say 1960. Who knows, for example, about the Bohr-Sommerfeld work? Is it important? I'll suggest QM or QFT...

can some one tell the history of cloning to me? but i really want a nice project.or maybe someone send to me site about cloning.

How could we possibly chart its history? The Greenpeace website cites ice core data as backing them up (what? no references? :smile:), but then we would have to have some gas isotope ratio that is used to pin down some quality.

I am looking for books that can help me to answer the following questions. 1. How Newton and Leibnitz independently invent calculus. 2. What were the controversies that followed. 3. How did the two theories continue to evolve? Did one theory win over the other? Can you please recommend...

I have to preapre a small oral presentation on the history of mathematical conjectures, highlighting the most important. One of the main question this revolves around is if a mathematical conjecture ever slowed down the advancement of mathematics. If anyone could give me pointers on where to...

Hello everyone: Im doing a research on the history of "modern" physics theories (namely relativity and quantum) trying to understand its role in a more general historic proceses that gave raise to a whole explostion of cultural development (from psicology, to cinema, with artistic vangards and...

Information Technology is actually a history of regression. I started programming in Basic on Commodores and PCs in the early 80s. It was fast to learn and fast to put ideas into practice. In fact I would argue that 99 % of all IT programming problems were already well solved just using some...

well, the obvious answer is linus... (atleast he did the kernel, GNU coders coded lots of linux too) but there were rumors going on that linus copied code off of minix. i found a nice history articile made by the coder of minix. nothing revolutionary about it. he dissmisses these rumors...

I have an 8-12 page history paper due wednesday morning and I have written only 1 page so far :groan: Any suggestions on how to get it done in an easy way? If I could, I would seriously pay someone $100 to do it. The class is so boring, I just wish they would give me a B and let me go lol...

Hey, From a Philosophy of Science angle, I'm trying to argue why concepts (say, scientific hypotheses) survive even when they don't seem to be succesful. I thought a great example would be fusion.:biggrin: Now, I'm not that big on particle physics (I've a Bachelor in Engineering Physics...

I apparently am lame at googling things, so I'm wondering: Where can I get 2 or 3 good sources of information about the history of Advertising, over the period of the last Forever or so. Thank you in advance! ^-^

Hello, Many of you have written scientific papers and here's my question: Do you think it is good to write some history about the topic you're writing on? For example, let's say I'm writing a paper on gravitational force and I added in intro a little history of brilliant discovery by Newton...

Just thought maybe someone would be interested :redface: It's a special two hour modern marvels. http://www.historychannel.com/modernmarvels/?page=upcoming

I had to laugh at some of the criteria for (humanity) discribed in this Wiki article, http://en.wikipedia.org/wiki/Humanity, to be exact i find it hard to point a finger at the time (humans) came into the evolutionary picture, ie how many genes separate humans from chimps, how far is a chimp...

Who created Physics Forums? Who is its founder? Does anybody owns it?

Rovelli history of science and some QG stuff at his site it is good to know about the history of science (truism---everybody agrees I think) for one thing it nourishes your skepticism because because you see in concrete detail how scientists have been on the wrong track so much of the time and...

Tonight on the History Channel at 7pm CST, "Warrior Queen Boudica". I hope it's done well. It's 2 hours.

How did words get there pronounciation, example, once, is not W,once, knew is not K,new, why is vacuum, not vacume, or vakume?

I am searching for a book that describes with depth the history of physics from Galileo, Newton, etc. to Einstein, especially the formulation of the principle of relativity and the laws of motion. Most of the treatments of the subject I am aware of (mainly internet sites), do not point out the...
