Experiments Definition and 460 Threads

Hi, I am currently in the process of completing my final year mechanical engineering thesis, which compares the dynamics of damped drumsticks (not the chicken ones, the drum kit playing ones!) with those of a conventional, undamped drum stick. I now am up to the point where I need to...

Hi all, I was wondering if there are any quantum experiments that I can perform at home? I am talking about basic experiments by using equipments that I can purchase easily on the market - like polarized films, laser pointer etc...and how can I construct those experiments? Thanks in...

I understand the sensitivity and confidentiality of some of this data. Its so difficult to archive or access data for this experiments (coated particle and pebble irradiations at material testing reactors: IVV-2M, R2, HFR, AVR, Dragon etc.) as well as the current irradiation programs...

Does anyone know of an experiment that shows that the electrostatic and/or magnetostatic forces have a finite speed, i.e. transmission time? I think I remember reading somewhere that Hertz devised experiments that showed that one or the other or both effects had a finite transmission time. In...

OK, I have an assessment task to create a 3D model of SOME of Einstein's thought experiments involving trains and mirrors, and present it to the class. Therefore a minimum of 2 thought experiments. The task is unique (ie each student is required to model a different part of the course), and I'm...

So I've been thinking about the slit experiment again... I did some googling/searching for literature but was unsuccessfull for finding the following variations on this subject. What happens when the slits are very long? (very thick sheet) What is the material (Z) dependence? What...

Can someone please help me understand the phrase "melt wire experiments" as used at the AVR fuel testing analysis and maybe why the such a choice of phraising. I would aso appreciate if I could be referred to either papers, journals or web links where one can get information and probably the...

Hello, I just read about the the ten most beautiful experiments of all times. The top winner was the double slit diffraction by electrons experience carried out by Claus Jönsson . This electron diffraction experiment, I think, has been chosen as remarquable because it stages the...

What do you think are some of the coolest, most fun, or most interesting chemistry experiments to do at home, and how did you do them?

Please have a critical look at the lines below: The simplest derivation of the Lorentz transformation simplified: J.M.Levy "A simple derivation of the Lorentz transformation and of the accompanying velocity and acceleration changes," Am.J.Phys 35,615 (2007) arXiv:physics/0603103 revisited.[1]...

Will it blend? :smile: This guy is nuts and this blender scares the hell out of me! Glow Sticks http://www.youtube.com/watch?v=l69Vi5IDc0g&mode=related&search= Marbles http://www.youtube.com/watch?v=3OmpnfL5PCw&NR=1 Fake Diamonds...

when performing a double slit experiment using photons it is said that if you fire individual photons that over time as more photons are fired the interference pattern starts to appear. My question is how do they define a single photon? what is the method that they can fire one photon at a time...

In what kind of experiments does the fermi statistics show? What kind of experiments have been carried out to verify that electrons obey fermi statistics? This fermi statistics stuff has been quite theoretical only in texts I have encountered so far.

In all descriptions of the http://en.wikipedia.org/wiki/Michelson%E2%80%93Morley" I know of, the two arms of the interferometer are at right angles to each other. Does anyone know of an experiment which, just for completeness, tried other angles? If not, does anyone know of a reference with...

Is anyone currently researching the inner monologue? Where can I find information about experiments to alter the inner monologue? Are there any websites which have "audio tools" which, when listened to, can positively alter the tone and function of the inner monologue? Cheers,

I Have two questions in my mind about the double slit experiment about the electrons, i would be glad if you guys could clear it up. 1)When we try to observe which slit the electron is going through, how exactly do we go about making the measurement? what kind of "device" or "technique" do we...

Right. Even well-documented observations that do not fit easily into a preconceived notion of how the world should work, may be rationalized away or just neglected. One example of this is the observed mean acceleration {\dot n} of the Moon; from lunar laser ranging experiments this has the...

I am looking to read up on some recent experiments that provide evidence for the expansion of the universe and I don't know where to start.

I wonder what the actual conclusion was, besides that it wasnt of use.

Two new papers on beautiful experiments were published this month concerning the Wave Particle duality of the photon:[FONT="Arial Narrow"][SIZE="3"]Paradox in Wave-Particle Duality S.Afshar et. Al. in Foundations of Physics. http://www.springerlink.com/content/q110r82074w03277/fulltext.pdf...

In visible light, what is the spatial dimensions of the photon itself. I'm interested in the experiments they have done to prove how big the photon is.

I don't understand why data has to be in a specific significant numbers? Why significant numbers? Can't it be decimal places with the appropriate unit? What if you multiply two values with different sig figs? Why the answer should follow the least sig fig value? Why not decimal places?

Even though in optics experiments we assume that the sun rays are parallel, we can clearly see that the sunlight seems to diverge from the sun when coming through the clouds. Whats the reason of this discrepancy?

Hi people, i am really in a deep trouble and i will be so happy if anyone can help. Any tips will be so appreciated and make a real different to what i am going through at the moment. i have got two question to answer. 1. Experiment of boundry layer on a flat surface : giving dtails of how...

Are there any experiments which test special relativity? I know of the Kennedy–Thorndike experiment, but it involves light. I am curious whether a different kind of experiments showing relativistic effects like time dilation or length contraction have been performed (I'm thinking of experiments...

Where can all the classic papers by the experimentalists that layed the foundation for nuclear physics be found?:confused: Rutherford, joliot-curie, fermi, lawrence, Hahn ect. Im very interested in reading exactly how they setup there experiments, the conclusions they drew and so on.

This is from my Physics practical experiments. The experiment is to find the refractive power of the prism for different colours and also to determine the dispersive power of the material of the prism. My question is how does the refractive index of the material of the prism vary with the...

can anyone help me find a simple experiment that i would be able to use to guide me to construct an investigation design report?

hey does anyone got any completed physics experiments at the college level??

This question has, no doubt, been answered before here ... but my quick search came up with nothing. I'm interested to know what 'two-slit' experiments have been done, and published, using things other than photons. In particular, versions in which 'no more than one in apparatus at any...

I'm going to get back to experimenting soon and I would like some experiments. Something cool, fun, but with a meaning, a goal. Useful products would be fun, too.

I assume this has been done, but I have not seen any papers on it. For example, with the Voyagers traveling at however-many-tens-of-thousands-of-mph with respect to us, we should be able to measure the slower tick of their internal clocks (e.g., slower signalling). Perhaps this hasn't been...

I caught this gem in an article in today's New York Times - it was inconspicious and the writer didn't seem to notice it. It's a quote from Dr. Steve E. Abrams, the anti-evolution chairman of the Kansas state school board. See if you notice it. (You may need to read it twice!)...

Does anyone know what the LHC will be capable of when it's running at high speed? I haven't really been able to find what kind of experiments the physicists will be able to perform with the collider. Just wandering what the plan was for this baby, what we can expect to learn, etc.

I read about experiments that modeled black holes as a liquid passing through a lavel valve at supersonic speed, the point were the water went supersonic was like the event horizon of a black hole for sound - the sound could go in but not out. They were looking for sighns of Hawking radiation...

Hi all, I read about the beam splitter experiments in Brian Green's most excellent book The Fabric of the Cosmos. I am obviously missing something and thought I'd ask here. Forgive me if I sound ignorant; I am well educated but lacking in advanced physics (although fairly mathematically...

So it seems I can earn a little extra credit in one of my courses by volunteering for experiments that are ongoing in the psych dept. I'm thinking about doing it. Anybody else ever do this? I hope there's no electric shocks involved if I can't find the cheese fast enough. :frown:

A kid I've talked to on the internet's able to do his own chemistry experiments at his house, but where did he get the materials? I've lost touch with him as I've only talked to him a few times, so could you guys help me out here a bit? And tell me some safety precautions if you decide to...

I have to place two acids and two bases from a previous assignment on a pH scale using the information I acquired during that particular experiment. The problem is, I couldn't get all the materials I needed so I didn't get to do the assignment. I've been able to figure out what vinegar's pH is...

On a recent thread about cloud chambers, a question popped into my head. My knowledge of cloud chambers is that one can see the "path" of certain elementary particles as they pass through the chamber. If, say, we had an electron passing through the chamber, do we have to assume that the...

anyone got some good web sites about experiments of physics? I would like to do a few experiments but i am not very sure the procedures.I don't want my house blown off !

:confused: Hey ya, I need to design 3 different experiments to find the specific heat capacity of a metal block. I have got 2 but am just stuck for a third. The two i have are: Method of mixtures Heat up metal block in a water math, transfer to a cold water bath and observe the temperature...

Today many scientists' or physicists' research is mainly based upon mathematical calculations, and not on the real experiments. Mathematics partially reffer to reality but the other half is far from the reality of our world. Hence many theories and studies in science today are away from trivial...

Different link: http://www.gutenberg.org/etext/5001 If you assume a standard clock, say the second on Earth at sea level, you will notice a difference between the second of this clock and the second of a clock on top of Mt. Everest - assuming that these devices are identical. An experiment...

It seem that internal conflicts in theoretical explanation are not good enougth to change the present state of phisics. That is, even dought we have chargeless, spinless, massless photons, or colored quarks, or dark matter an energy, entities of which we know very little more than the fact that...

First of all, sorry if I put this in the wrong board. Now, I have to do as much expreriments (for a school project) that would help to prove any information about molecules, that is very important to me, so if you know any experiments that would fit, then could you please write in here, or...

I admit i do not have a clue, does anyone know what experiments have yielded some advance for humankind, and if the cost of said experiments is worthwhile.

Soon Earth bound problems will curtail all asto physical experimentation, funding will be cut to next to nothing, think i am wrong?
