New technology, new discoveries, even old tech/discoveries that we never heard of -- what have you found interesting? Let's (try to) keep tech toys to another thread.

I was going to start with cavitation (roughly the study of the behavior of voids or bubbles in liquids) using some factlets I have picked up over the last year like:

• [>]the instantaneous temperature of the inside of a collapsing bubble is 20,000 degrees K. (4 times the surface temp. of the sun) and follow up with
• 
  
• [>]capturing a hydrogen atom in a bubble formed in superfluid hydrogen - the bubble was then painted with pin-point infra-red light and the bubble split into 2 separate bubbles each either containing the hydrogen atom and neither containing the atom but never one containing the H atom and the other not.

But I am not going to start<see note1> there because when I tried to follow the google links, it sucked an hour out of my life (in the middle of writing this). So I am actually going to start with an old concept called a soliton. The first recorded sighting of a soliton was in 1834 - gawd this sucked another couple hours, ouch.

So I offer <see note2> this Atlas of Cyberspace so you can waste your time too. The research is old, some of the links are dead, but this is one of the best sites I have found for visualizing where the denizens of daniweb live. This site parses the web into hundreds of different points of view

enjoy!

<note1> - sorry - bad joke
<note2> - consider this old technology

So, gravity is a monopole?
Time could be a monopole unless it's circular.

Do we have any tripoles?

There is a cute story about R Feynman and time - other physicists would come in and ask him a question about particle interactions. He would chase them out of his office, then an hour or so later come up with an answer. Normally, scientists would brainstorm together but not Richard. So one time, the burst into his office about 20 minutes after asking a question and he turned bright red and tried to hide some papers. Then he admitted with embarrassment that he was not able to keep all the interactions in his head so he had to draw diagrams to cheat. Those diagrams are still used today (60 year later). The connection to time is that if you look at one of his diagrams that produce anti-particles and consider it as a time-line then the anti-particle can be viewed as a regular particle moving backwards in time.

Do we have any tripoles?

Curse you sneekula!

I just got sucked into tripoles - a short list before I dive in and disappear for a couple of hours:
The generation of tripoles from unstable axisymmetric isolated vortex structures
Emergence of tripoles in nonlinearly perturbed planar vortices
The life-cycle of tripoles in two-dimensional incompressible flows
Passive Neutralization of Myoelectric Interference From Neural Recording Tripoles

I should be looking for work but I think I can take a day off to dive into tripoles

[twomers]

In some physics expeiments they make very long and narrow bar magnets to simulate monopoles. Odd-opoles are awkward.

[GrimJack]

I thought I would revive this old thread because the US Navy has revived the old 'cold fusion' experiments. I am looking at some of the links - the second has a lot of alternate theories of what they are seeing.

i figure id add this link since space is something that really interests me and well this series of clips (10 in all) has got some great pics and info from the hubble space telescope .... mabee you guys will find it interesting

[GrimJack]

Well, I thought I would look at the farside of science

[chriswellings]

ok im really skeptical about gohsts .... id have to see 1 to beleive but still i love watching clips like theseat night by myself and in a dark room lol http://www.youtube.com/watch?v=ttdEkr-0Hxo&feature=PlayList&p=8E7279B790F37FF4&index=1&playnext=2&playnext_from=PL

there are quite a few on you tube that are just plain redicculous but there are also a few that make ya stop and think ........mabee even send a few chills down ya spine lol

[chriswellings]

oh and with that last link its not just gohsts it all sorts of unexplained

[GrimJack]

I thought I would let you hear the Music of the Spheres - Jupiter

[chriswellings]

yeah that was a great 1 did ya listen to the alien voices one?

[GrimJack]

Bring the environment back into your world - I definitely want one.

I wonder what is the purpose of this finding something that other
end of the universe ?

Try to implement something that helps other ppl. For a example
think how many ppl today is without the lack of food ?
Can you write the code for a automated green house that maximize the food production capability of that green house control
system ? I think that's a good idea.

I wonder why NA$A is spending a huge amount of money on useless things.

I have to say this whey NA$A laugh their Voyager 1 and 2 rockets
they had a risk of the destroying the world ! Don't believe that ?
there is a risk of necular fuel that it uses , and some equations of
the orbit calculation doesn't completely unable to prove out of
complete risk margin. Many ppl in the USA against it, but the
president not be against for it , and sined up that's how the
politics are going in this world ( common to the USA too).

What are you asking? What is your point?

"Without a lack of food"? what does that mean?

Can you write the code for a automated green house that maximize the food production capability of that green house control system ? I think that's a good idea.

This is a good suggestion.

I wonder why NA$A is spending a huge amount of money on useless things.

Of all the possible different ways in the United States of America that money is wasted, you choose NASA? Are you on drugs or just crazed?

I have to say this whey NA$A laughdid you mean 'launch'? their Voyager 1 and 2 rockets they had a risk of the destroying the world ! Don't believe that ? there is a risk of necular fuel that it uses, and some equations of the orbit calculation doesn't completely unable to prove out of complete risk margin.

I think I can tease something from this - you think that the Voyager rockets contain nuclear fuel and you fear that they could have destroyed the world and that and something about orbit calculations and margins of error. If this is your meaning, then you are completely ignorant of what the nuclear fuel was, probably completely ignorant of anything relating to science and/or engineering. The nuclear fuel used could have been crashed into the earth, detonated with plastic explosives, and it would have the same effect as doing those things to lead except a Geiger Counter would react to the fuel - it would have hit the earth like any other lump of matter. It would not have 'gone nuclear'; it would not have irradiated anyone (unless it hit them and getting hit would have been a bigger problem).

Many ppl in the USA against it, but the president not be against for it , and sined up that's how the
politics are going in this world ( common to the USA too).

What the hell is your point with this sentence?

so what you saying is that voyager missions are complete safe ?
well I'm not a PHYSICS expert but a PHYSICS expert who I believe
told me this. I don't know those mathematical rambo jumbo. I'm
just a learner . and so please don't hurt me . But I talking with a point and info , just google about this , you may seen many PHYSICS experts are commented about this issue . But the US president at that time neglect those risks.

This type of energy source is controversial because of the slight risk of an accident, especially during the launching of a plutonium-powered spacecraft. Critics fear an explosion could spread plutonium, which can cause cancer.

me sorry too !more than that if something went wrong and ppl get cancer , they will be getting grumpy than
you.

From that article:

To limit health risks, the plutonium is surrounded by multiple layers of shielding, including thick graphite shells, ''designed to withstand the extreme of impact and temperatures associated with a mission abort,'' the National Aeronautics and Space Administration says.

Like I said in my previous post - the most dangerous thing that could happen is that the lump of Pu238 would hit you. It is an Alpha emitter - this means that its radiation is stopped by skin; it will melt at 1100+ degs F but won't boil until 5800+ degs F; it is less poisonous than arsenic.

Of course it is a dangerous substance but not anything to worry about - do not eat it, breath it, or smoke it. You could survive eating it but not breathing it. It has a half-life of 84 years.

This is another of those "of all the possible things to worry about, you picked one of the stupidest" ideas.

so you agreed that there is a risk. Many ways you can argue and
prove the safe factor is high like you speak. Applying many rambo
jumbo mathematical theories and so on ! oky you win , but there
is only a one earth for you , your children and children after them.

I know about this , many ppl can contentiously argue about this
safe factor. when you ask this question from a gov environment specialist they will say it's safe. you have to believe the analysis or
facts from a non government independent source.

I don't need to prove it or analyze it . or put down some large
Σ ( µτ ) = ______
things and make you difficult to understood and then prove it.
( I personally hate the mAc book).but knows one thing.

Paracelsus, the father of toxicology, once wrote: "Everything is poison, there is poison in everything. Only the dose makes a thing not a poison." You can drink enough water to poison yourself (it dilutes the electrolytes in your body so much that there is no electrical potential and your heart stops beating). Alcohol is a poison; the spices that you use to make your food more interesting are plants' attempt to poison/protect themselves from insects; cars are the most dangerous thing in your environment.

You do not seem to understand the concept of risk; if you do not understand risk, how can you argue about the danger of something? Yes, I can accept the idea that the world belongs to everyone - please explain how that applies to the current discussion.

If you discount any and all arguments that do not support your ideas, how do you expect to hold a discussion with anyone? You seem to be saying "I know what I know and there is nothing you say that will convince me otherwise" and thus imply that your mind has snapped shut and nothing can get in.

[chriswellings]

lol well didnt this thread just go way off point?

i thaught this was just links to things we found interesting?

so in another words you telling what you need is the mathematical proof of the risk .Sorry I'm at 3rd grade math.

However this is related to the discussion. think the universe is a endless thing , so suppose that you invent a new theory or a
simulation model about a black hole , how can it be helpful for the
ppl how are staved ? how it can be helpful for the peace of our
world ? how it can be helpful to a person who is going to die from
cancer ? what I telling is searching about something that
millions of LY away never help to today's world's problems.

Ahhhh, now I understand where you are arguing from! You believe that if it does not put food on the table today, it is not of any use. You are at 3rd grade math; you should stop going to school and get a job. There is nothing you are learning in school that will feed a hungry person tonight. There is nothing you are doing in your life that will solve world problems.

Or is it possible that if you finish school, you will be smart enough to feed the world? Is it possible that you will learn something in school that might solve the world problems? Do you see? Do you understand that we are unable to predict to what use the knowledge we gain will be put? Wanting to put a man on the moon gave us the technology to put computers in the hands of half the world which allows the spread of knowledge to everyone. The search for knowledge gave us a world free of small pox and may soon free the world from polio.

What I am trying to say is that we don't know what learning something new will teach us but not learning something new will never get us anything.

Heh,heh - it is my thread, I can do what I want er - actually that is why I started the thread and why I keep reviving it but sometimes, I get distracted by a bright shiny object. In this case, it was a mind that might be bright and shiny but also might be dull and useless - only time will tell.
