Ok, I know what happens (big fireball : ) when you add water to a chip pan fire, but I'd really appreciate it if you guys (and gals) helped me out with SCIENTIFICALLY describing WHY adding water to the pan causes the fireball. It must contain words like "immiscible" and so on... Thanks in...

Hey, are there any good software packages to create scientific diagrams? Specifically for optical bench setups including lenses, lasers, mirrors, beam splitters etc. Surely there is a powerful but quick way of making them using some sort of program? Any ideas or recommendations? Thanks, Ben

-81^(1/4) = -4square root sign 81 =-3 how do i key this into my calculator: = "-4square root sign 81" *note I am working with a $20 casio* thanks ~Amy

Just a quick question! I'm writing a report for a unit that is meant to be written according to a "standard scientific report" format. So for the most part I know how to set it out, but I was just wondering about my calculations. I observed a star and to make sure that it was the right...

Can somebody explain to me the values, operating principles, aims, role of government, method and example of government involvement, possible problem, and strengths in those 2 type of socialism?

"string theory is a complete scientific failure" by Daniel Friedan to make it clear, I am quoting Daniel Friedan, a former string theorist at Rutgers from hep-th/0204131 "The long-standing crisis of string theory" "String theory has no credibility as a candidate theory of physics...

There are many misconceptions about things and people in our society. I say one of the most misunderstood groups in America is scientists. Can you give some of the many misconceptions of Science,Physics, scientists,and physicists?

If anyone knows any scientific facts that haven't yet been expained by science please post them here. Thank You.

I would like to know what are the software tools most used to: -write scientific papers; -do graphics; -do statistical analysis. At the moment, I'm using LaTex to write my scientific papers, and R to make some graphics... What do you think about these?

Is kaos more fundamental than any scientific rule, is it kaos that prevents us from knowing our origin and futuer?

I draw the forum’s attention to the fact that the so-called Schwarzschild solution is not Schwarzschild’s solution. This can be easily verified by reading Schwarzschild’s original paper. Furthermore, the all too frequent claim that Schwarzschild obtained the black hole from his solution is...

There is a lot of debate going on in the media and on forums like these as to whether or not anthropogenic global warming is real. Here is a link to an article in the AAAS Science Magazine that states there is no disagreement between climate scientists as to the consensus, not majority or...

Most scientific papers are probably wrong!? from New Scientist. http://www.newscientist.com/article.ns?id=dn7915 Well that would certainly undermine the credibility of the scientific community. The rush to publish could be a factor, as well as publications from questionable work, e.g...

The question isn't whether a theory is testable now, it's whether it's testable in principle. For example, there's nothing in our current understanding of string theory that precludes it from being falsifiable. The main problem for string theory is the same problem that continues to torture the...

Coca-cola TM (maker of Gatorade TM) has filed a lawsuit against Pepsi TM (maker of Powerade TM) in a federal court: http://news.yahoo.com/s/ap/20060321/ap_on_bi_ge/pepsi_coke_lawsuit :smile:

Scientific evidence to prove religions?? Since there is already another thread taking into count religion and science,I thought of posting this thread here. I found this site actually from a link from a commercial on the main site here. The auther clearly trying to prove a religion by using...

http://television.esa.int/default.cfm Anyone with some inside information?

Are there any sort of essays or generally accepted criteria for accepting one theory over another? I ask, becuase for most any theory, it seems that you can find evidence for it. If you did your research, you could come up with tons of evidence for a totally wrong theory (like all the evidence...

In https://www.physicsforums.com/showthread.php?t=105441", I expressed my unease with the great number of as-yet unexplained entities and parameters that are required to keep concordance cosmology on its feet. I have a philosophical and ultimately mathematical reason for this unease, and it has...

Do you think karma is a logically scientific concept and can be proven to be true?o:)

I've met and read about many researchers who study more than one field, usually studying one field of science with applications using math/cs or a crossbreed eg biochem, biophys, biopsych etc. As some of you have guessed from my posts, my ambitions lie in using 3D simulations(math/cs) for...

I know there has to be a program better than Microsoft Word. When I try to move images/graphs around in MS Word they jump around all over the place. I end up having to reformat a paper 20 times because everytime I add a image, it effects the whole paper. Or if MS Word is popular how do you...

Hello folks, I'm a budding physicist who needs advice on science-related software that's used in The Real World (TM). I've recently had a look at Octave, Maxima, matplotlib (python plotting), gnuplot, Ocaml and "The R environment for statistical computing". Problem is, I can't make up my mind...

I know zip about biology, but I know a little physics. Before Einstein's general theory of relativity challenged it, the prevailing scientific theory of gravitation was Newton's theory. In the minds of most physicists, the issue was resolved in favor of Einstein's theory as a result of an...

Hey crew, Playing around with the aforementioned software and I am finding myself becoming agitated that I am continually having to switch between Text and Math. Hit enter, and its back to Text. What I want to do is make it Math always until I decide to toggle. Not sure if this is...

What are some scientific ideas you think had the greatest impact on society? It'd be nice to have a few that aren't "obvious." (don't mention the transistor :-p)

I am doing a 30 minute presentation on scientific racism that will focus on IQ tests, standarized tests, and eugenics. If anyone has any information that would help me I would appreciate it. I am against the information that claims white individuals are genetically superior. I have so far...

One interesting notion that strikes me from time to time, like now, is that if String Theory [ M Theory] is correct or nearly so, the greatly anticipated theory of everything, or TOE, is not a theory of science and never can be. Rather, M theory stands as a philosophical proposition, and it...

Significant Figures and scientific notation! how come 8.231x10^3 - 5.25x10^2 = 7.706*10^2 ? and how come 350 - 10.5 = 3.40x10^2

NewScientist: "Most scientific papers are probably wrong" http://www.newscientist.com/article.ns?id=dn7915 This is no surprise to me if we are considering papers in the social sciences. But I wonder what those of you in the other sciences think about this?

This is probably slightly off-topic, so I must begin my post apologizing for that. :smile: I am seeking a free scientific word processor that can do something similar to the tex bracket command on this board, so that I may make symbols for integration, differentiation, summation, et. al...

OK, for once, *I* don't quite know where to put this (since it covers almost the whole gamut of issues). I'll move it if I find a good suggestion on where it should go. In any case, if you are in the US, or any vested interest in how poorly civilian scientific endeavor is being supported, you...

hi...can someone pls suggest a scientific breakthrough (recently:2-3 yrs) that is related in physics..aomething easy to understand yet interesting...please please please...super thank you! :smile:

Anyone of you guys read this month's Scientific American?? The one on that our inflationary model of our Universe may have to be modified due to the unpredicted patterns of the mono-poles and dipoles and other multi-poles of the CMB. Certain harmonic Spheres were missing? then they talked...

What's the difference between: 6.6725985D-20 and 6.6725985E-20

Due to a peculiar combination of events, I've been thinking about human nature and the nature of scientific inquiry... a scary thought. For example, how does a scientist answer the question 'why is the universe exactly the size it is [feel free to insert the gravitational constant, speed of...

Martial artists or people who are interested in martial arts probably heard of "dim mak", where a person can paralyze or kill an opponent by applying a force into some "pressure points" in his body. It's like what some of us saw in Kill Bill 2 when Beatrix finishes off Bill using this art. I...

This is a very entertaining reading. It does give a bit of a glimpse of the "actual practice" (if there is such a thing) of the inquiry process within the daily workings of physicists. http://arxiv.org/abs/physics/0506191 The title does imply that there may be other future parts to this...

In which? Have you taken any prizes?

Peer-reviewed journal articles are probably the most well known medium for scientific communication, but oral and/or graphically presented material can be just as important. How much importance was put on sound oral communication skills in your undergraduate or graduate careers? Were there...

i am still under the impact of revenge of the sith and i wonder one thing so much related to those Jedi skills: is there any formal scientific evidence about human beings being able to move/fire/destroy... things with nothing but thoughts and/or by forming energy waves or whatever with...

How many hours does a scientist have to use as research hours in order to solve the highest level of scientific problem?

Scientific Method. 1. Observation and description of a phenomenon or group of phenomena. 2. Formulation of an hypothesis to explain the phenomena. In physics, the hypothesis often takes the form of a causal mechanism or a mathematical relation. 3. Use of the hypothesis to predict the...

hi, could anyone please advise me on hand-drawing a line graph (this is for a scientific lab) graphing the following values? X -2.92 -3 -3.09 -3.22 -3.40 Y -0.86 -0.91 -1.02 -1.15 -1.28 My teacher said he wanted the values to fill the page, but to still be able to see the...

A pole of scientists gives a surprising variety of opinions: Address:http://www.spiked-online.com/sections/science/sciencesurveyA-B/default.htm The one that stood out to me, in the context of PF, was: "Science is disputative." Alot of people echoed Feynman's answer to this question...

First of all, if you haven't read Moonbie's journal entry on this, YOU SHOULD! I have decided to start a thread on this because I have a few "opinions" and questions on it, and I didn't think it was appropriate to add them as comments. So Moonbie, I hope you don't mind... What does it...

holy cow i feel dumb... i know these are super easy but i just can't figure it out. 1. --- (10^2)^8 divided by (10^-2)^3 2. --- 1.2x10^-6 divided by 4.2x10^-2 if anyone can give me a kick in the brain it would be awsome 1.--- 10^22? 2. -- 2.9x10^5??

After reading about the scientific method here and there in this forum, I'm considerably confused. Would someone be so kind as to explain the scientific method. And, perhaps, comment on its applicability to the day-to-day activities of working scientists, Thank you in advance. Regards, Reilly...

Hi, I'm interested in learning just how scientific research is done—specifically for Astrophysics. I would like to start some preliminary research for the Siemens-Westinghouse competition in October, but I'm wondering if research can be done in Astrophysics without a multi-billion dollar...

Ive dowloaded the first chapter they have available in .pdf and thought it was a great read. Wondering if any of you have read this and would like your input on what this guy has to say. What he proposes in the first chapter vastly impacts our views of physics and how the universe works. Ive...
