Bubble Definition and 221 Threads

It is often said that electrons do not follow classical paths, especially in the context of electrons in atoms etc. I have absolutely no problem with this, as I do have a academic background in physics (but extremely rusty). Non-classical paths, uncertainty etc. being the case, what is then...

A spherical air bubble originating from a scuba diver at a depth of 18 m has a diameter of 1 cm. What will the bubble's diameter be when it reaches the surface? (Assume constant temp) a. 0.7 cm b. 1 cm c. 1.4 cm d. 1.7 cm I know this problem shouldn't be all that difficult, but I'm not...

http://physicsweb.org/articles/news/9/7/8/1 Strangely enough, while it looks similar, the experiment is actually different than the earlier Taleyarkhan experiment. Other than that, it is still equally controversial. Stay tune for more development in this saga... Zz.

Hey, my friend and I have worked on this problem for about 2 hours straight (from our online HW) and can't get the answer right. The help offices and the professor are closed/gone for the weekend. Can anyone please help?! :eek: At 80.0m below the surface of the sea (density = 1.025g/cm3)...

For this experiment, you don't have to go into the lab. I thought it would be a breeze but I was wrong. The problem I'm having is collecting the data. The figures given are to be used to find the data but I don't know what I'm looking at and how to find the tan planes. Is there someway to...

Why don't neutral particles leave tracks in the bubble chamber? How is the bubble formed, is it condensation around ionised hydrogen, or around the particles?

According to this release, bubble fusion (i.e. using ultrasonic waves to induce the rapid collapse of bubbles causing the atoms at the center to fuse), has been convincingly demonstrated in the laboratory. http://www.rpi.edu/web/News/press_releases/2004/lahey.htm#cool At least two movies...

Bubble Fusion - verified?! http://www.rpi.edu/web/News/press_releases/2004/lahey.htm#cool: could this finally be it?

Dear Sirs, i need your help in this question, truthly i can't solve it. so kindly asking you to send me an answer with proper explanation if possible. the question is: an air bubble has a volume of 2.5 cm3 when released at a depth of 40m in water. What will its volume be when it reches...

Bubble problem---momentum Here is the problem I'm having trouble with: Some solidified lava contains a pattern of horiznotal bubble layers separated vertically with few intermediate bubbles. As the lava was cooling, bubbles rising from the bottom of the lava separated into these layers and...

Hey everybody! this is my first time on this site and i really hope i'll get an answer 'cause i don't know it... ... and to the point: 2 bubbles are at the same depth in the ocean. asumption 1: the temperature is the same in the whole ocean. assumption 2: the pressure is smaller as you go...

Show that inside a soap bubble, there must be a pressure \Delta P in excess of that outside equal to \Delta P = 4 \gamma /r where r is the radius of the buble and \gamma is the surface tension. My first question is: The pressure on what!? Are they referring to the pressure on the bubble...

Ok, I am not a physicist or a mathematician. I'm more of a philosopher, because its the only discipline people who are broke can afford and still be good at. :smile: Still, I had a puzzling thought the other day, and I was wondering if at least the concept held some water. Please feel free...

Does anyone know where to find some high quality bubble chamber photos? Any information would be appreciated.

someone told me to post this so i could get more of an intelectual veiw on it. i was talking to someone i work with about our veiws on the universe and possible natures of it. i came up with a theory of us living in a giant bubble. the universe is a bubble and and though it seems giant and...

I work with computer graphics as a hobby, and I want to create a system to model a cluster of bubbles. Has this been done realisically before? I don't want to do anything too complex, but I've read that bubbles only join at certain angles. How could I set up a script for bubbles to blob together?

I've got the answer to this problem, but I didn't find it clear enough as an explanation on how to backsolve it. I was wondering if you guys could help me with it. Thanks! Here it goes... Answer: "1.5 cm/s downward (the bubbles rise but layers descend)." Problem: "Some solidified...

Does anyone know if an electric field passing through a column of conductive fluid would excite the gas on the perimeter of a bubble in that fluid, if the gas were prone to be excited?

This Paper may be large, but it is a must for some pretty far reaching consequences for Cosmology. http://uk.arxiv.org/PS_cache/astro-ph/pdf/0312/0312347.pdf I will astounded if the paper is not seen in the near future as a remarkable paper of astronomical foresight and will be a paper...

When there is an explosion on Earth the void created is quickly filled with Earth debris. When we view an exploding star there is no debris (understandable) but there is a large bubble with a void in the middle. Why is the universe NOT shaped like a large bubble with a void since the accepted...

To know what I'm talking about you'll have to do a little experiment... Go to your bathroom, take some soap and foam up your hands. Make a "bubble" with your index finger and your thumb, then reflect the light from a lamp in the "bubble". After a little while oil-like rainbowcolored patterns...
