Scientific Definition and 550 Threads

Why is it that when i cook sausages i can brown them on one side, but, when i turn them over to brown the other side they turn over on there own. I am sure there must be a scientific reason, maybe steam trapped under the skin, any way the only way i can cook them all round is by sticking...

This is not a question about relativity per se, but relates to it sufficiently I hope. Standard values for many scientific constants are defined, and ideally in the most universal way possible. For example, the standard length unit, a meter, is defined with respect to the distance light travels...

Hey, Im an undegrad engineering student and I am really interested in high end physics and meta physics. I also like to read a lot so I've got myself a large number of books that I have to carry around with me. Recently I decided to buy an iPad so I can do some reading (seeing iphone's...

Monique reported about a fraud in science here. I don't want to hijack that thread but I'd like to discuss some ethical aspects about that. Ethics doesn't seem to have an own forum. Arguable it could be in P&WA, I don't know. There are several instances of fraud like that, the most notorious...

Why can we never be certain of our scientific theories? The reason i love mathematics and physics is that the rigorous knowledge they impart about reality or what lies beneath it. Yet the more physics I study, the more I realizes how very little we know. What is gravity? what is force? What is...

1. Vinko Rajic is talking about in his videos on YouTube that he can use telepathy all the time and 100% correct on few kilometer. Uri Geller could give evidence for telepathy at Stanford University. 2. At Edinburgh University, experts conducted controlled experiments to see if...

Who is credited with coming up with the modern scientific method? I think it was either Galileo or Francis Bacon... Note, by modern scientific method I mean: Do experiment. come up with theory to explained observations. Test this theory repeatedly with different experiments. If theory...

Does anyone know the best place if any for a layman to publish a scientific paper or article?

The "Error and Trial" article from Scientific American is rather interesting. It reports on 6 scientists and a government official being charged with manslaughter for contributing to the deaths of 300 people in an earthquake in Italy. Internationally, scientists are outraged, claiming the...

I have some problems comprehending what the objective of ITER is. I'll explain: The stated objective is "a large-scale scientific experiment that aims to demonstrate that it is possible to produce commercial energy from fusion". However; 1) ITER will never produce any usable energy, so...

I have noticed that political threads get locked or terminated far more frequently than is the case with more scientific ones. Sometimes this is because posters wander far off the OP topic, but more often it appears that incivility simply reaches unacceptable levels. I assume that most of...

I'm a freshman now in college and I'm looking to buy a scientific calculator, since graphing calculators aren't allowed in my exams. I've been running through high school with my TI-89 in class, though in senior year I became interested in RPN and have been using an HP-48 emulator for Android in...

1. What is a good scientific method template for college students? I need something that is more complex than your general 4-6 step process. e. I've looked over the web and have not really found much.They are all very similarly simple.

Hi, I'm stumped trying to learn how to use the GNU scientific library. I installed X11, Xcode and gsl library using MacPorts on my computer which is running Mac OSX 10.6.8. I've used Xcode plenty in the past year for generic (simple) c programs and it's worked fine, so I think all the...

Hello, friends: I just got done studying a chapter in a physics text that explains how heat transfers from higher-temperature objects to lower-temperature objects. Unfortunately, that chapter said little about why heat transfers from higher-temperature objects to lower-temperature objects, so...

(Not really sure whether it should go into Academic of Career Guidance - it's kind of on the boundary) I've recently obtained a MSc in financial and actuarial mathematics, and have been working as actuary assistant for about a year now, likely planning to become qualified. I've come to...

I've tried a few methods of plotting histograms from unsorted data, but they're all extremely involved (ROOT) or look very "childish" (online tools). What's the easiest way of plotting a histogram from a unicode text file with numbers in it? Thanks in advance - need the histograms for some...

"Scientific Thinking Graphing" -Determining the Mathematical Expression Homework Statement Ok, so I recently got an assignment for "Scientific Thinking Graphing Practice". Basically, I need to take a data table that will produce a curve shaped graph and turn it into a straight lined graph...

Hmmm. I hope you will understand my slight nervousness at posting on the philosophy forum with all of its tight rules and circling, predatory mentors. My hope is that by following your instructions closely I’ll avoid the awful finality of those thread closing talons. So, moved from the...

This is a simple question. I am calculating the force of two masses based on the Universal Law of Gravitation. I am setting up the equation as G (gravitational constant of 6.67e-11)*mass1*mass2 all divided by the distance between the masses squared. This particular question is about masses...

I'm in my first year of theoretical physics master and I'm considering of following the path of scientific simulations. At the moment I use C for my simulations. I would additionally like to learn an object oriented language. I followed a course in Java about 2 years ago, so that would be easier...

Is it better to start learning Python using a introduction to python book (Think Python) or a scientific programming book (e.g. A Primer on Scientific Programming with Python, 2009)? I have little to no programming experience. I'd use python solely for physics computation/simulations. I was...

When I was younger, I used to imagine myself fighting bad guys and saving the world. I still do, to some extent. But now when I think about being a superhero, I think about time sharing my unique skillset to the academic and space community. I think I would fly to Europa and break through the...

Hey I'm curious what sort of strategies people use to efficiently read and understand physics papers. I've never really thought much about it until now, but I'm sure some ways are more effective than others. A simple google search yields some excellent tips, but most are geared towards less...

I'm about to sell a scientific paper (give authorship to another person), publishable to a moderately high impact factor journal. What would be the price range? :-)

If this question has been asked many times before, then I apologize, but I am simply interested in the opinions of others. Do you think that all scientific truths that can be discovered, are discovered? As an illustration, do you think that if Einstein had not discovered his special theory...

Are two electrons identical in every way? I think that's what we know so far, but is there any research that proves/doubts this or any reason to expect why it should or should not be the case? I ask because no two things in (the macroscopic) world are absolutely identical, and so I wonder if...

I have wanted to be a paleontologist my entire life. I am currently a senior in high school, going to college as an evolutionary biology major next year. I know that I have plenty of time before I really have to worry about this, but how does one become a scientific researcher? Obviously I need...

A bit of unfinished business: I discovered this report back in 2008 and was satisfied at the time that it was legitimate, so I posted it in the UFO Napster - not to be taken as suggestive of anything beyond high strangeness from a seemingly credible report...

just a quick question... I was wondering what is a more scientifiacly correct term for bubbles. e.g. it was noticed a bubble layer began to form on the surface of the magnesium. what word could be substituted for this? I seached around and found that apparently the scientific term for bubble...

Homework Statement Hi, Sorry if this is the wrong part of the forum (or even the wrong forum!) but I'm a second year undergraduate physics student, trying to use TeX to write a lap report for the first time (I've previously been using MS Word). Basically before I start writing the actual...

I only have a BSME with a very small amount of work experience (I graduated recently). I'm hoping that there is a decent scientific journal out there that would seriously look at my paper regardless of my credentials (or lack thereof), review it, and if they find it correct publish it. Also, I...

Hi, is there the concept of light in an Atom??

Hi, I'm meant to use the scientific notebook to answer equations but I'm stuck on one of the equations. I want to solve for x and y in: (x-13)^2+(y-31)^2+16=441. I used the solve + exact function in Maple because I need to find two variables, but the x and y values in the answers were decimals...

Do you know any book to be read by the general public written by someone that works on field theories ? Even tough I am physicist, I appreciate the informal and very intuitive description of theories that appears in those kinds of books.

Do you know any book written by a great physicist where he talks about black holes? I always enjoy reading the more relaxed way of talking that appears in popular scientific books such as The Fabric of Cosmos - B. Green.

Late last night, I got an email from the APS news thing (American Physical Society I believe). I'm a member, so no doubt those of you who are also members got this email. For those that didn't, here it is: Just to give an overview if you didn't read it all, there are some major cuts being...
