Scientific Definition and 531 Threads

Hi everyone! I'm new here. I'm currently doing undergraduate work in biology and part of me is thinking about going into grad school, but I'm afraid i might be very misinformed about what it's like. I love science and nature, but part of me thinks I'm romanticizing scientific research...

FIRST: Please, I don't what this to be a String Theory bashing thread. I've seen and even participated in plenty of those. I think that String Theory is interesting and that if and when we find a Theory of Everything that it is likely that String Theory will at a minimum have pointed us at least...

I'd like a mathematical and/or scientific critique of the assertions made at the following website: EDIT: link to crackpot post deleted Note there are some comments on the side that are directed towards a mathematical critique of the poster's assertions. These critiques appear to be valid...

Hello all! I'm wracking my brain - I could swear I once read that Einstein had decided to have a bunch of his work sealed for 75 years after his death. Scientific work - not the personal letters that were sealed for 20 years. I can't find any reference to this on the web... Maybe it was...

This is not a cynical question, though it will sound that way. OK I have taken a bunch of stats courses, but I am not in the social or political sciences. How do you formulate a political poll that is unbiased, in a scientific sense? Or is that impossible? I know some build their...

Hi there, I am a third (maybe second year for US standard?) year mathematical physics student and I have just realize that I do need obtain some programming knowledge. My university has a compulsory courses that teaches java programming, but, looking around I've come to the conclusion that...

I would like to step up from the pop-sci level of understanding LQG to something more like a real physicist's understanding, but one thing that's hanging me up is the SU(2) stuff, which I don't understand, even at a hand-wavy level. Falling back to the pop-sci level to regroup, I remembered that...

Here we see an in depth scientific model that attempts to explain why Pie is > Cake. Given the evidence, I think you cannot disagree. http://hyperboleandahalf.blogspot.com/2010/03/pie-verus-cake-scientific-approach.html ;)

http://www.scientificamerican.com/article.cfm?id=rummaging-for-a-final-theory I cannot see anything new at all there. I hope other people here can help me see something relevant here. I found this while checking Garrett's twitter.

I have been wondering about the state of Scientific Journalism recently after reading an article in a UK newspaper discussing the recent http://www.nature.com/news/2010/100822/full/news.2010.423.html" having formed 4.568 billion years ago. The article does not appear on the newspaper's...

As pointless as it is, let's speculate which of the two breakthroughs will come first!

Dear all, Here are some questions about explaining symbols in a journal paper. a) Do you explain every symbol in the equations? For instance, when you write down Maxwell's equations in a journal paper, do you, after the equations say "where \vec{E} denotes the electric field, \vec{H}...

Hi all! I'm doing my bachelor in physics (have presumably one more year left) and I already started concerning about which area of physics I want to specialise in, since I have to do a Bachelor Thesis in a semester from now. I also don't know if I want to stay at the university after...

What exactly does this mean? I have a paper due in Biology, where I had to read a research paper on Clathrin Coated Vesicles and answer some questions. Well that was kind of easy, until I got to the end and it asked "How do the findings in this paper contribute to the scientific body of...

Need help urgently please... so i have this book called "Science Matters: Achieving Scientific Literacy" written by Robert Hazen & James Trefil which seems to have basics of all fields of science compiled together in it. check this link for more info...

http://www.nag.co.uk/sc22wg5/ It looks like Fortran 2008 is going through its final steps of standardization. What does this mean for scientific computing? Since people still use Fortran 90 despite new revisions up to 2003, will this go under the radar, or will this be a new and useful...

:rolleyes: ... not sure if this is the right place to post this. Hi, I'm looking for something like GSL but with programs instead of routines. For example, there is a method that was developed in the 80's for solving the time-dependent Schrödinger Equation (M. D. Feit, J. A. Fleck Jr. and...

Hello everyone I'm currently new here and was hoping to find some guidance to my scientific career. I'm 14 years old, I was born in 25/05/1995(mm/dd/yy). My favorite sport is Hockey. My favorite team is...Pittsburgh penguins. My favorite player is Sidney Crosby. I like chemistry, I always work...

Seeking "scientific tenets" For example, the medical profession has, "First do no harm"; a tenet establised by Hipprocates. Are there any similar ones for physics? Like, "first test it" or something like that?

Has anyone seen the part of Iron Man two where they combine the major scientific advances of the past centruy into a single scene where he makes a new element? For those who haven't, I will summarise; - He builds a particle accelerator in his front room showing no evidence of large...

A lot of scientific programs are CPU-intensive, so speed is important. Pointers have to do with memory management, which I presume is important since there are often so many array values that memory management becomes important. yet, I don't see it used very often. Are they used very often?

I am in need of a scientific review paper which involves the use of quench-flow or stopped-flow techniques, and was written after 1995. However, the only review papers I can find require that you pay to read the article, and I just don't have the funds (being a poor college kid). Are there any...

The "no miracles" argument against scientific realism Let's assume that our best scientific theories tell us something true about the way the world *really* is, in an ontological sense. And further, for simplicity, let's assume a deterministic interpretation of those theories. In this view...

For my second writing GenED at Towson University I have to develop a proposal. I am proposing a scientific writing course designed the help science majors with writing journals and researching. The idea is to take this before advance lab classes. Problem is I can't find any data to support...

Is Kurzweil considered a quack (crackpot) by the scientific community?

Hello. Further to :- https://www.physicsforums.com/showthread.php?t=390324 Are there any scientific teams / Researchers actively trying to achieve a) teleportation b) creating things via atoms - without an existing item (Ie Star Trek Food producer machines) I've googled - But...

Is anybody else getting spammed by "Scientific Research Publishing"? I've been busy unsubscribing from I-don't-know how many "journals" from this group and I don't know how they got my name, but I get at least one email every day or two. Many of the "journals" listed on their website seem to...

I do not have a calculator that does matrix stuff that would be great for my classes this semester. I don't want to spend $100+ on a graphing calculator since I use MATLAB at home strictly now. I am looking to solve simultaneous equations, matrix operations like det,eigen,mult,...etc Any...

Homework Statement How do I solve for x in cotx=2 by using a scientific calculator? What do I have to enter? Homework Equations N/A The Attempt at a Solution I know that I can enter tan^-1 (1/2) to find x, but is there another way to do it on a calculator?

I'm having some trouble with a few problems that I'd really appreciate some help with. 1.) The velocity of a space shuttle is 8 x 10^3 meters/seconds I have to convert this to kilometers/hours. I know there are 1000 meters in a kilometer, and 3600 seconds in an hour. Next I have to...

Here's a very interesting You-tube interview Russia RT interview. The BBC has responded by announcing it's review of it's reporting of climate science BBC to launch review into allegations of bias in its science coverage. Here's the Mail's webpage BBC probes bias in its coverage of science and...

"Questionable" article in Scientific American? "Questionable" is my polite assessment. It's highly speculative at best, but specifying distances to "copies" of our galaxy (and ourselves) is cranky as far as I'm concerned. I'm not paying to read the full article. What ever happened to Scientific...

So I'm having a bit of culture shock going from academia to industry. I've come into a situation where management wants a positive report to be given to a customer. The customer gave us some equipment and wanted us to perform an experiment for them. The results of the experiment is...

Earlier today, I posted on this issue and a lively discussion ensued. I'm happy to have received several responses. As I recall, each of these took issue with one or more of my posting's claims. An administrator inadvertently deleted the thread of our conversation before this conversation...

How reliable are peer reviewed scientific articles? I'm asking this question because someone on http://slickdeals.net/forums/showpost.php?p=25802864&postcount=913" claims that you can pick who reviews your article so you're not really getting an objective point of view. This was in a global...

I thought this was the appropriate place for what is essentially (at least to my mind) a pholosphical idea. Has there been a fundamental change in the way scientific experiments are evaluated? Has the standard of proof shifted, as indeed it probably has to, due to the phenomena we are...

Highly informative discussion It's in a foreign language but that's OK because there are excellent subtitles. I decided to remove URL because may be too controversial, but will try to give googlesearch keywords

Has anyone used the new e-readers with scientific papers? I'm looking into getting a kindle or something similar. But am concerned about the formating of the pdf files on the small screen. While it would be nice not to have to carry a stack of papers the screen needs to be easy to read...

Or how many people here use Linux?Which distro?I'm using Gentoo. Edit -- I was also wondering about scientific tools for Linux like OpenFOAM.

Is there a 'proof' for this law? or is it experimentally derived..Thanks for reading

Shortly after the year 2001, to now, there have been more increasingly violent earthquakes, hurricanes, tsunamis, tornadoes, etc... than in any other decade in history. I wanted to know if there is a natural, geological, and meteorological explanation for this. Not too long ago, there were Two...

I've been working on various database portal projects for the last ten years at work that all deal with the same general type of data. I've been wanting to work with different types of data and thought about working with scientific data for a change. I'm mainly looking for a hobby that I can...

Something that always freaks me out is the idea that time has no end, every time I think about it I get properly wierded out. Recently I started trying to get my head around the start of time, either there being one or not being one, and that's almost as bad. The qustion is, are there any...

Is there a compendium of peer-reviewed journals that have been shown to be wrong? I've heard of scientific journals that only have required two reviewers. How often does rubbish get by; not just typos and simple mistakes, but fundamentally unsound rubbish? Is there a remedy process for...

Hi. I have high functioning autism and like many other people on the spectrum I think predominantly in pictures and that's how I learn scientific concepts. Every concept I learn I represent it with a picture. Unfortunately a lot of the books on chemistry in particular (physics and biology I have...

I would like to ask for scientific clarification on a less commented part of Iran's nuclear technology preparations. It is fine for us to do the politics here as well, but that is also discussed in lots of places. This site is particularly suitable for scientific/technological background you...

Hello, I hope someone can shine some light on the following questions: The std scientific method (observation, hypothesis, experimental verification or falsification) assumes that the phenomenon being studied happens (is observable) within the time span of human experiment, let's say a human...
