The Physics of Beer Bubbles
Roland Piquepaille writes "Yesterday, I told you about virtual beer. Today, we follow two North America researchers who are studying the physics of real beer bubbles. 'Singly scattered waves form the basis of many imaging techniques such as radar or seismic exploration.' But pouring beer in a mug involves multiply scattered acoustic waves. They are more complex to study, but they can be used to look at various phenomena, such as predicting volcanic eruptions or understanding the movement of particles in fluids like beer. They also could be used to monitor the structural health of bridges and buildings or the stability of food products over time.

On Topic
Sorry, I'll take my beer without the scientific mumbo jumbo. If I wanted to get technical, I would drink wines and learn how to sniff corks.
More research on the subject. Very interesting stuff.
See my journal for slashdot ID's by year. Mine created in 2005. http://slashdot.org/journal/289875/slashdot-ids-by-year
Isn't there something more worth while that scientists could be researching?
The game.

They could use the random interactions of the beer bubbles as a random number generator for crypto. This is much cooler than the plain ol' lava-lamp random number generator that Sun uses.
Plus this gives the added advantage of being able to recruit college students that are torn between a degree in Art History, and one in Math by telling them that they'll be forced to work with beer. It's a Win/Win situation!

Yeah but have they split the Beer atom?
And can it be used to power a starship drive?

"Yesterday, I told you about virtual beer.
Translation:
"Yesterday, I made inane commentary, ripped off images from the parent site, and quoted blocks of text whole-sale. I did this instead of submitting a story to Slashdot with links to the original site, because that wouldn't get me and CNET ad revenue. And now I'm doing it again today."
Can we please get a Roland filter, a la Jon Katz? And can Slashdot please stop linking to useless blogs?
Please help metamoderate.

Desktop fusion was all about bubbles and the enormous pressure they can create. Bubbles are indeed worth studying.
I can hear them now..
guinness beer guys: "Mixing math with beer? Brilliant!!"
I have to return some videotapes...
I work at a bar, and sometimes i see an interesting phenomenon in beer glasses. If you leave a draft beer out and let the foam fizzle away, after a while(but not too long or the foam will disappear completely) the foam will coalesce into a ring shaped pattern of circles, equally sized and spaced and at the same distance from the rim and centre of the glass.
It takes about half an hour for this pattern to form, and for the life of me, I can't figure out what makes it!
Anyone?
We haven't seen this level of advancement in beer technology since Einstein split the beer atom back in 1988.

Ahhh, someone is taking up his groundbreaking research into beer bubble paths. Soon we shall be able to find out irreproducable his work truly is!

Scientist: Our group would like to study beer bubbles. Board member: Denied. We need a cure for cancer. Scientist: But it's really important -- like that Norwegian study which proved that penguins don't fall on their back when observing passing planes. Board member: Sorry, but it's not viable. Scientist: You can have 20 percent of the beer. Board member: Will $200,000 do?

...if you put a beer into a soundproof booth, are the bubbles still going to behave how the researchers expect them to?
Sorry, but all Roland posts are inherently blog-hit-whoring. This one has direct links to his ZDnet blog. He does get paid for that, right???
Oblig.: Pls. tag as ohnoitsroland -- and thanks.

Yes, there is, the effect of CO2 produced by the fermentation of beer and how that causes global warming, so we must stop the production of beer right now!!! And save the world from global warming.
Besides, the rain fall that is happening on the east coast of the US will drain into the Atlantic and cause an imbalance in the salinity of the ocean and cause the gulf stream to dis-function, as it is thought to have done in the 1300's and cause another mini-ice age, so who cares?
Bud ain't beer so it's hardly on topic.

Although I won't go give Roland a pile of cash, I think it's worth mentioning that there's this amusing little video regarding beer bubble physics.
It's all on why bubbles in Guinness move down.

Nice try.

I know a lot of people think Roland Piquepaille has 'reformed' because hes no longer linking to primidi, but Roland is still whoring Slashdot for ad views and the like - its just that he is now employed by zdnet. The links in the summary all link to his new blog run by zdnet.
Im not saying that its wrong to do this - but dont be fooled into thinking that his new links are somehow 'genuine' and hes not whoring as usual.
This is a research topic often studied in university. I knew engineering students who often studied beer bubbles. One in particular studied beer bubbles prior to doing fluid dynamics assignments and exercises. In preparation for the final exam, he included the same ritual (examination of beer bubbles). He got 89% on his final exam (and passed the course with a similar grade: A- (cum laude). He mentioned something or other about having a nip before the exam helped him to relax (but you have to believe me when I tell you that I had no idea what he meant by that!

This research does not seem to be fair enough. These findings were already theorized by the French mathematician René Thom; he developed the catastrophe theory between 1968 and 1972. http://en.wikipedia.org/wiki/Ren%C3%A9_thom He published his work "Structural Stability and Morphogenesis" (1972), where he states the catastrophe theory may explain natural phenomena such as the beer bubbles, the tree barks, vulcanic activity, earthquakes, sea waves, and even a stock market catastrophes... It's a shame this PDF doesn't even mention such fundamental theories. You may find more about this theory in: http://en.wikipedia.org/wiki/Catastrophe_theory
... so I could post how much this made me think of Young Einstein. I also knew this is the only place in the world where other people actually know about such an awesome movie. I feel at home :)

There are a few Roland Piquepaille filters available - they take the form of Greasemonkey scripts running in Firefox
I use this one: http://userscripts.org/scripts/review/5735/ it's called NoRoland - if userscripts.org is down (again), the author (Dave?) hosts it on his own site too - http://davephp.net/
It's very effective - all I see of Roland's pollution now is a greyed out article box with the words "This is a slashvertisement. Please ignore!"
Most of the time I choose to "ignore"

Nowadays the thing I ask myself is "will this job be of any value if civilisation collapses?" If you work in a call centre or IT, be very afraid...but if you can fix a broken irrigation pump or generator, build a house from traditional materials, grow food or brew beer, you probably have a future. Why beer? Well, apart from the likely demand for the product qua beer, earlier societies produced "small beer" (i.e. low strength) for general consumption because the brewing process killed fecal and soil bacteria, and the alcohol then kept the product sterile. In a society without clean drinking water, and no sewers, beer was what stood between you and dysentery.
