Scientific Definition and 514 Threads

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." a lot 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...

course called "scientific and engineering computation" I am taking a course called "scientific and engineering computation" using the MATLAB program and I was just wondering where should I post questions on this topic?

Does the scientific method mark the coexistence between belief and actual science, and describe tenets that involve a religion of information? Its prediction of world events may apply equally to measuring the electron's mass, or consequently to the conviction in its own efficacy. The...

I'm wondering whether I should enroll in this course. This is the book they use: Did anyone ever use this book? If so let me know if there's anything worthy in it for engineers

Scientific alternative to the anthropic principle by Baez http://arxiv.org/pdf/hep-th/0407213 To me this is an heroic paper

can anyone tell me the scientific reasons why airfoils are used to straighten airflow (e.g. turbulent flow from a fan or propeller). i know how they are used to produce lift, but cannot see how they straighten airflow. thanx! o:)

I'm a computer science major in college right now. I'm going to wind up taking mostly computer science and mathematics courses. I've taken some lower-division calculus-based physics (physics for scientists and engineers-type material), a decent freshman-level biology course, and I had some...

This has puzzled me for days [short term memory is kicking in]. When was the last time a career crackpot suddenly got it right and resurrected that pet theory with a stroke of brilliance? My unscientific survey indicates that virtually all great discoveries have emerged from people who worked...

"Anytime you see a turtle up on top of a fence post, you know he had some help" -Alex Haley What would be the scientific approach to figuring out how the turtle got on top of the fence post? Thanks, Glenn

How to use Scientific notation?? How to use Scientific notation?? Is This feature availble to all? Make this stuff Sticky

Although I think that is a waste of time to discuss about IQ, since the high number of threads dedicated to this topic I pose the following questions: 1) Is (was) scientific research being directed by people with high IQ? 2) Does IQ measure creativity? And the most interesting (for...

I'd guess the answer is obvious :smile: My nextdoor neighbor's field is Linguistics. She specializes in Sociolinguistics---what can you tell about society from the words people use, and avoid using. She can listen to the news coverage of an event and often get an essay out of the...

Moral statements are often thought of as having nothing to do with science. As such, they have always been thought of as having something to do only with religion, customs and rules of the society. How true or realistic are these claims? Is there any way in which moral statements or utterances...

Hi all, Can anyone tell me what we can expect in the near future from a science perspective? I know it is not possible to travel faster than light but is teleportation possible? TVs without screen? -benzun

Is possible a systematic unification of the scientific knowledge? Make it sense? If so, what would be the profits and limitations of any interdisciplinary work in so distanct areas as Neurosciences, Ethology and Physics? (excepting technical applications of one field on other) Is being...

A theory is scientific if it bets its life on at least one prediction that it makes about the outcome of a doable experiment If a theory is part of science then there's a possibility it'll get shot down by an empirical observation---by some measurement----the theory makes predictions of so...

My phys II prof said there were no law of physics or anything laws like math chem that were named by the inventors first name only the last. I know there is no way that is true i have been thinking of all i know and I can't seem to think so maybe he's right. but just a thought if anyone can...

Is anyone here a member of the SCIAM book club??

Does anyone can point me the most recent works on science philosophy? What are the most recent researches on the scientific method and how it is defined today? Can someone please indicate me recent papers?

I wanted to point out a great article about our up and coming Hydrogen Economy. This article comes from the May 2004 issue of SciAm and it gives nice snapshot of the state-of-the-art. Not available for free AFAIK, here is an internet link and brief...

So here's the deal - I am applying for this special program at the university I am going to study at, and the next stage is to prepare a 10 minutes lecture about a scientific / technology / engineering subject. The shmucks in charge of this program printed the letters on May 9th but I only got...

Title says it all!

I would be interested to hear comments about this site http://www.sciam.com/ since we are thinking of subscribing. Are there preferred alternatives that can be recommended? Our interest area is physics so perhaps there are things more specific? hey! i just saw there is an interview...

What, in your opinion is the most significant scientific institution of all time: The Royal Society Library of Alexandria Etc ...?

Dear Readers, I am Dr. Raj Baldev, Cosmo Theorist, author of Two Big Bangs created the Universe (Formed in Eternal Space), a new hypothesis, which I wrote being inspired by Stephen Hawking's appeal given in his book "A Brief History of Time", reproduced below: "However, if we discover a...

My physics teacher deducted a point from my test for using E instead of x10, She never specified that she didn't want E, and in my opinion, E is much easier to write than x10. She said it was not the proper way to write it. What are your opinions? -- Klaser

I am writing a paper on the Theory of Everything, and it's effect on mankind. I was wondering, how do you think the public would react if a theory of everything was discovered? How would the public accept a theory such as this (so large scale)? How would society change in general...

What do you predict will be the next overarching, revolutionary saltation (paradigm) in the philosophy or theory of science?
