Experiments Definition and 478 Threads

I'm about to do this project in which we will prepare and perform an experiment and then later tell the class about it. All this in about a week. I'm now trying to come up with some interesting experiment to do during this time. I'd really like some help on the subject. I'm looking for an...

I posted this in reply to another topic in the relativity forum, but I realized this might be better as its own thread here in QP forum. I have some questions on photons being able to go faster than c. I just finished reading QED by Feynman (great book). One of the things he talks about is...

what are some of the experiments performed that upholds the predictions of SR?

Is there a site where I could see what people have done in various experiments? For example, I will be doing the verlocity of light experiment and would like to know what kinds of data analysis people have done so I can get some ideas as to what I could do with my data. Is there any such...

I want to surf some website(chemistry experiment, include vedio, lab report and other useful things about experiment...)the experiment may be the tiration, techniques, experiments or ions... Because I need to do experiment and lab report in school. I am a form 7 student! :smile: :smile...

Patrick posted the following interesting link in another thread: I'd like to discuss this some more. Whenever I have read about these experiments I have always hoped to see the results of one in particular but I have never found what I wanted. I can guess what the results would be, but...

I have been roped into running a science club for kids age 11-15. I would like to do loads of fun experiments with them, but I'm having a mental block. If anyone knows of any demos that might interest this age group, please let know. The topics are: Sound, Light, The Solar system, Forces...

these are lab experiments in which i have gathered but i still haven't performed them... can anyone please determine the basic answers or give tips for the upcoming experiments? :approve: thanks very much~ Making Salted Eggs/ Pickled Eggs I. Objective: To illustrate osmosis/diffusion in...

Hi, I've been thinking about too quite simple ways to create what I believe to be faster-than-light speeds, and would like to know your opinion. First experiment: 1. Shoot a laser pointer on the moon on a clear night sky. 2. Move the dot through the diameter of the moon. If a person...

I am needing to design some experiments for High School Students to explain Osmoregulation without harming the organism or experiments concerning excretory organs or systems. Does anybody have any ideas or references I could turn to? Thanks Nautica

Let say I have prepared two identical particle, both describable by a wavefunction Psi, whereby, Psi = a*1 + b*2, where, 1 and 2 are two stationary wavefunctions. If I perform an experiment to find out the systems' energy, this is equivalent to operating a Hamiltonian on Psi. Operating...

I have recently become interested in physics, and I have been reading different material in magazines and online. I don't want to blindly believe everything I'm "told" without doing some kind of experiment myself to be certain, before I accept these laws and theories. Does anyone know of some...

I am a freshman at USD ( chem major). I absolutely love chem lab. I have been think about preforming some experiments at home. Is this a bad idea, unsafe. I have had basic college lab knowldge, i.e. what to do if you spill an acid, ect. Is it safe to buy chemcials (an or labware)...

I'm in desperate need of any testing experiment that shows the conservation of angular momentum. It should be something where an objects shape or radius changes while it spins, and calculate the angular momentum at each moment in time to see if it's conserved. If anybody has any ideas at all...

In my bio class, we're learning about genetics currently and watched a video demonstrating mendel's experiments with pea plants. Something in the video didn't seem right to me, and my biology teacher is horrible and couldn't understand my question. In the part of the video in question, it...

My question is rather simple: Are there experiments where they have measured length contractions?

My friend and I have a lot of ideas for liquid nitrogen experiments (and we will be safe! :)), but we have no idea where to order it from. If from an online source, try to be specific. If in reality, try to give a little input on the process. Thanks.

will somebody smarter that me please tell me how this works. okay, here goes. experiments done in the yesteryear told us that if a photon was split (?) the two parts would act as if they were still together. is this correct? this is the first part of my question. i'll get on to the...

These are sentences I've red regarding this subject: - Time doesn´t flow for a photon traveling at c. - There is no after neither before for it. - Therefore, no causes and effects. - A photon doesn't have age, it doesn´t matter if it was born in Big Bang or in a experiment yesterday...

Experiments to describe the band structure of bulk (solid) materials? I just want to know the name of some of the most used techniques to describe or obtain information of how the band structure of the material is. Not by theorethical calculations, just experiments. For example, let say I...

spooky action at a distance. what is it? what were the experiements involved? can they be debunked? briefs preferred to links to long-winded articles.

We need to write down why knowing the speed of life would be important to us personally. Can anyone come up with suggestions? I would appreciate it. I would also like to find experiments or information on how to measure the speed of sound. I would appreciate it if you provide me with...

Is anyone else here a big fan of the anime series "Serial Experiments Lain"? personally, i think it rocks, though it also manages to make The Matrix series look simple and straightforeward in comparison.

Hiya! I have questions that i am hoping someone can confirm my answers to, please. 1) In youngs double split experiment, if the separation between the slits decreased wouldn't the distance increase between the interference fringes? I say yes, i used this formula to derive my conclusion...

Coming to the end of the college year and we need some fun/dangerous experiments to try in the remaining lessons any suggestions? preferably experiments that involves flames, sparks or loud bangs. Didn't know whether to put this in the Physics section or not so i just put it here, feel free...

I have revisited Naudin site. He is still around with the lifters, and it seems nobody has been killed by X-ray radiation. Good. Besides this, he now is suggesting a couple of funny ways to destroy your mom microwave, by generating a small plasmoid inside. This guy is probably the nightmare of...

Can anybody recommend any *interesting* lab experiments suitable for an undergraduate nuclear physics course? Thank you.
