As far as I know, there are 4 distinct ways to publish articles; Traditional journals; peer-review (behind closed doors), the authors lose some rights by publishing, access is limited. Publishing takes months. Open access journals; The same as traditional journals, but the access is not limited and sometime, the authors keep more rights. Publishing takes months. arXiv; no peer-review but a system of "endorsement". PLoS One; open peer-review process, articles are never rejected because of perceived lack of importance, they're rejected only if the content is not scientific (i.e.: creationism). It's easy to write answers and criticism about an article. Publi…

Okay, so, for this project, I'm doing a regression for the data I measured and the data that was generated(an estimation made by a computer). I am also trying to find the rate of error between the two values. So, when I try to find the error, do I measure how far away the generated is from the measured, or how far the ordered pair that they make up is from the closest point on a 1:1 line? Or, am I going about this completely wrong? x3 Thanks for any help you can give me!

It is generally accepted that the Amazon basin once drained into the Pacific, and that when the Andes formed it begin flowing in the opposite direction. I am wondering what the process would have been like, I see alternatives: * Would it have changed direction immediately once a certain threshold was met? * Would there have been two separate basins flowing in separate directions and the Eastern one slowly grew in size? * bWould a large part of South America be flooded into a giant dam, with outlets on both sides? I cannot clearly see what would have happened.

The darkest material, made from carbon nanotubes has been made in a US lab...according to researchers it's 'the closest thing yet to the ideal black material, which absorbs light perfectly at all angles and over all wavelengths.' Please see the BBC article below... http://news.bbc.co.uk/1/hi/sci/tech/7190107.stm From the article...

Yesterday I watched a documentary by a respectable channel that "proved" the existence of dragons in the past, is the theory approved in paleontology? (sorry about my english, I'm greek)

When I was in the sixth grade (longer ago than I care to admit), the elementary school I attended administered a program that has benefited me ever since. Not long before graduating, a single week was set aside to prepare departing students for their move up the ladder of higher education. For five days we no longer attended a single classroom, but rather six, as would later be the case in Junior High, High School and College. Separate teachers instructed us on a variety of topics: Music, History, Art, Science, Literature, and, my favorite—Critical Thinking. This class was taught by Mr. Anderson, a teacher unfamiliar to me at the time. Although the specifics of Mr. An…

I’m not sure what to make of all this, but it is interesting. Any comments or impressions? http://mainstreamuniverse.blogspot.com/2008/03/cymatics-bringing-matter-to-life-with.html

[copied by swansont: This came up in another thread] This is a good example of what I'm talking about, so I appreciate that you brought it up. You've done something above that even the IPCC couldn't do -- determine factually that global warming is caused by humans and declare the debate over. Millions of scientists can't do that, but here at SFN it's a proven fact that cannot be refuted. That's awesome. Can I get in on it when we publish? ... and you don't see a problem with that. Well okay, good on you, but I do. Sorry. Like I said, I don't think it ruins the board, because I've watched you hear people out on the subject and require that responders…

What is antimatter? Can anyone tell me completely about antimatter.

I wanted to know what goes into the process of plastic manufacturing… for example are molds used? Are there coatings that are used on the molds, if so why and how do they work? I have recently come to understand that the foundry industry uses coatings on sand cores to improve the metals surface finish… how closely are the foundry and plastic industries related? Thanks in advance!

http://news.bbc.co.uk/2/hi/science/nature/7254939.stm i was reading about this rubber thing... and wondered if this is using hydrogen bonds then it should form in to a ball or something like it... but i could not find anything from the internet... so what you think of this new rubber? and what you know about it? if it is like it is said it sure is cool thing

I'll give a quote from a website that got me thinking about predicting evolution. “As proteins interact in the cell, they rely on each others' characteristics. It has just been shown that proteins that interact with a lot of other proteins cannot evolve, or at least, only do so at a very slow rate. See Nature, 28 June 2001, and M. Kimura, T. Ohta, Science, 26 April 2002. They propose that this is because of great internal dependencies which inhibit the changing of the 'contract' of the protein. It is also noted that evolution does take place, but very slowly as both parts of the dependency need to evolve in a compatible way at the same time.” http://ds9a.nl/amazin…

I may soon present a scientific poster at a meeting (maybe the BMC in York). This will be the first one I have made that I will present. I may provide a link to my poster when I am happy with it. I was wondering if anyone here had any useful advice or tips on creating posters and presenting them? One problem I have is that my work is mathematical and largely algebraic so now nice pictures or diagrams (one diagram of fibre bundles). It is clearly not as pretty or artistic as some posters I have seen.

I just got my own SaladShooter for like $30 and I am baaaad. I've been without a food processor for a while, and I crave coleslaw. Fresh cabbage salad has to be extremely healthy to eat. In fact, a few years ago Science News described a study showing Russian women have not so much incidence of breast cancer and this was tied to eating cabbage. Anyway, my question: is it a mistake to make an acid vinegar salad in a stainless steel bowl? Once my mom sent a new set of stainless Farberware silverware, knife, fork, spoon. The instructions mentioned not leaving them in acid foods, implying leaching of some metal I do not need, like chromium or nickel. Is this indeed good…

Hi, I'm new to the forum but I have three questions regarding greenhouse gases. I know that N2 and H2 cannot become greenhouse gases so they don't do radiating, but I was wondering how they might influence atmospheric radiation, like with collisions, etc?? I learned in chemistry that CO2 has various "bands" at which it absorbs radiation, but only in certain regions that matters (like at wavenumbers of 667 cm-1 ). What determines which regions matter? I've seen an argument that water vapor is also a powerful greenhouse gas, and my teacher said she didn't know much about this, but the textbook said that water vapor has not increased much, where CO2 has. Any in…

I made this a new thread since everyone continues to discuss total solar irradiance (TSI)-CO2-temperature and the relationships with time. As a response to Jeremy in the other thread here, I created this excel file with data, and 3 graphs, one for TSI (1610-2000), and one for TSI (1950-2000) from data by Lean (2000), and CO2 and temperature data; CO2 prior to 1960 is from ice core data by Etheridge et al. (1998) and observational data after 1960 from observational data from Mauna Loa. Temperatures anomalies (base period 1951-1980) are from NASA GISS. TSI reconstructions are accompanied by an 11 year moving average. http://files.filefront.com/CO2+Temp+TSIxls/;952789…

I promise I'm not trying to make a point with this. I'm just curious as to how you feel the scientific community should treat these two groups that oppose basically what it as a body is saying. Now obviously there are some global warming deniers (or anthropogenic global warming, or whatever semantic games you want to play) and even a few Creationists on this site, so perhaps you're going to have a different opinion than us drones, and I'd be interested to hear those too. Is denying the scientific consensus on the origins and development of life and the universe analogous to denying the scientific consensus on anthropogenic climate change? Is one position more valid th…

(moved from Experiments thread) i am very poor in the lab skills.can anybody give me the tips:what should i followed to improve my skills?

Everyone knows that the traditional four stroke Otto cycle gasoline engine used today has an efficiency of no more than 30%. Given that the engine is so inefficient, why do we still use this old design? It's not that the engine reached its theoretical efficiency, because it comes short of that. So why haven't we adopted one of the many inventions that use gasoline to produce work but in a simpler and more efficient way? Countless engines, like the Bourke engine and many others that I can't name off the top of my head, can so the same operations of an Otto cycle but with fewer parts, smaller size/weight, and improved efficiency. Why are manufacturers still going for th…

Some times we see two rainbows. How they are formed? Will there be in the order of colors VIBGYOR?

This thread is all about this mysterious compound. Perhaps it will become less mysterious with someones strange knowledge. Substance in question : those mouse pads, that have that pocket of jelly on one end, for wrist support. Of coarse this pocket is sealed in plastic. Surely someone else has in curiosity or boredom slit it open and [painstakingly] removed the compound, had some fun with it, and then regretted it. I did. I'm going to be mysterious and not speak of what happened right in this post. But does anyone know what that shit is called?

Anyone know the way that a storm be created ? In which season, they appear a lot and its movement depend on which ones ? Thanks !!!

http://www.popularmechanics.com/automotive/new_cars/4237853.html?series=19 The question I ask is what kinds of new dangers do we expect with these ultra-small, ultra-light cars that are coming out now? The side-door impact support on this car more than meets the required standards, however, the size of the car does not absorb the impact like today's car would and inevitably it will get tossed across the street or into other lanes of traffic more easily and the people inside will be subjected to more jarring than would be normal. I'm not downing efficiency, but this looks fairly dangerous until everybody is driving these.

How much do the basic assumptions and beliefs of the modellers effect the models? Firstly may I make it clear that while this thought occurred while considering General Climate Models and AGW this is not meant as an attack on any or all GCMs. Secondly it is not about AGW or GW at all, but about the methods used to construct models in general. I know bugger all about how they're made so I thought I'd ask the question. Background. (Please note that this refers to natural forcings only) While reading various articles and papers on GW it became obvious that there has been a gradual shift in the perspective of Climatologists from the Gradualist to the (Semi) Catacl…
