Scientific Definition and 531 Threads

Here's a thought, often in history someone will find a detail that doesn't fit some theory, then will come up with a better theory which explains the evidence better than the old one (ex. Einstein did to Newton). Before Science, there were groups who said rationalism was best, and others who...

This question has to do with some annoying anomaly when expressing in scientific notation whole numbers that are multiples of powers of 10. For instance, 2000 is usually written in scientific notation as 2x10^3, implying that the original number has 1 significant digit. On the other hand, 2025...

This may be the wrong place to put this thread, but it appeared to be the best option. Does anyone know of an easier way to set up physics equations online other then finding the keystroke or inserting a symbol? It's a pain to hold ALT on my mac and hit every key trying to find an integral...

Does anyone have a link or some source for all of the scientific symbols used in equations like this one E=mc2, I know that one doesn't really have any sybols in but I mean like the really long and complicated ones (((THIS IS NOT HOMEWORK!)))

I have a question regarding the process of publishing. Is the preferred method to first submit to a pre-press (such as arxiv) or to directly send into a journal for review. If submitting to arxiv, how does one find a suitable endorser? Apparently one can find endorsers by reviewing topical...

i need to find a way to control the syringe pump in my lab so that i can control the flow rate in real time from the computer, ideally from a simple dial i scale up or down. the pump can connect to the computer using a rs-232 port and someone suggested to me that labview would be the easiest...

I'm doing a paper on how the scientific method in it's current form came to be. I've found a lot of interesting websites already, but not many that I would feel comfortable using as a source. Could anyone point me in the direction of some good books or trustworthy websites that give a good...

Hi I’m a 14 year old student and my school is having a science competition for the students in the grades above me, but i thought I would enter because I love scientific competitions. Basically the competition is a hypothetical scenario where you have a group of scientists/engineers and...

Dear Group, This new paper by two famous Princeton mathematicians named J.H. Conway and S. Kochen examines a particular case in quantum mechanics (QM) and then proves a new theorem which shows that if humans can be said to have "free will" then so do elementary physical particles. They...

In the stupid quest to know everything about a subject, i just wonder if there exist databases out there that include all the existing journals to search for an specific topic. I currently use Science Direct, but that is restricted only to Elsevier journals. For example, it does not include...

Up to the present, what concept formulated here on Physics Forums do you consider the most outstanding?

Dear PFers, I remember once reading of an article on scientific honesty, maybe it was in SciAm. Individuals passionate with science, making up a significant portion of the research community, may picture challenge as stimulating or even exciting. It is a great deal of pleasure when you...

I find it funny when various pundits and news reporters in the media constantly complained that the United states is falling behind in new developments in science and technology , and which to a certain extent, there is some validity to this claim , observing that the scientific literacy in the...

I am a freshman at a university (I'm 16 years old- skipped 2 grades in school) and I'm planning to major in physics. After reading more specialized books in the library, and having some discussions with professors I have come up with a couple ideas that I would like to develop further and...

Hi. I was wondering if anyone would share with me some insight about what calculator I should purchase? I'm a returning student in the fall, majoring in physics with engineering option. It's been so long since I've been in school though that I may end up having to take a trig/algebra II class...

Is the concept of god frowned upon?.

I was sitting in my kitchen this morning at 8:10am eating breakfast with my mom and sister present in the room when a glowing yellow & orange light appeared directly over the counter table across the room for no more than 2sec. At this same instance our electric garage door started going haywire...

The problem is attached... It asks for the answer to be shown in the form a,k. Whereas a is the base number and k is the exponent, with using the form of scientific notation.The answer I came up with was 9.782701624,1. I was told it's wrong and I don't know what the real answer would be then...

Hello, I've a program in FORTRAN which I need to convert to C#, there's an assignment statement like this: FC=10.e6 What exactly does it mean? Is it 10*10^6? or 10.000000? Do you have some tips to convert the FORTRAN program to any modern language (C#, JAVA, C/C++) ? Thank You

I am taking a project this year. As the title suggests this project is a maths project but I was wondering if anyone can direct me to some science field in which I could use stochastic models. I have very limited knowladge in science so something theoretical would be nice. Any books would be...

Hi, I wish to plot a 3d surface but as of now have not been able to! I wish to plot z=f(x,y)=[x²+y²-1]^1/2 restricted to the domain: dom(f) = {(x,y)|=1 ≤ x² + y² ≤5} Any step by step instructions would be greatly appreciated! Thanks in advance!

Has anyone heard of the journals published by this group, Scientific Journals International (SJI)? Their website is http://www.scientificjournals.org/ Are these journals generally respected in the scientific community?

Saw this interesting article and wondered what PF thought of it since its close to home. Personally I don't see the scienctific method being replaced anytime soon. http://www.wired.com/science/discoveries/magazine/16-07/pb_theory/#/ Edit: Because of its predictive nature that is.

How do you write in scientific notation "the (SI) units of x are..."? For example, the SI units of time are seconds. Is there any succinct way I can write this? Maybe it's like this: {time} = s ?

Scientific consensus as described by Wiki, http://en.wikipedia.org/wiki/Scientific_consensus Is not some thing that is set in stone, as at the bottom of the wiki article shows SC can change, so is it safe to make decisions on the findings of SC?

My vote goes to "WARNING: This product contains lead, a harmful substance in the State of California." But outside the State of California, eat all the lead you want!

After all, fortran isn't object oriented and it's used a lot by scientists. And a lot of scientists also use C, which isn't object oriented either. So someone told me that the four languages to know (for theoretical biology) are C, Java, Perl, and Python.

This may be a weird question, but oh well. Way back during the Scientific Revolution it would have been possible to define mass as acceleration divided by force right? Then you'd have F = a/m, and the units for force would be different than they are now.

I need help. =/ I don't know much about hypnosis and I wouldn't know how to apply it to the scientific method. Help?

I heard somewhere that the goal of physics is to describe the most amount of phenomenon in the fewest terms. I really like that for some reason. Of course then there is the scientific method, which I am less fond of. I wonder, in this day and age, is the scientific method actually limiting...

ok in my philosophy course we just started studying science and my teacher is TELLING us that the scientific method is WRONG. I asked him how and he says that because it doesn't work leads to wrong answers etc. etc. he pointed out about how we didn't know about organisms that can live smaller...
