This question is based on recent frustration: Has anybody studied the psychology of people that have a visceral reaction against Einstein's theories? I know...
first off there are experiments that show some there may be problems with the theory, therefore there is always allowed a question , any theory has a right to...
Hi folks If your culture permits it - "Happy New Year". I am contemplating building a semi autonomous robotic submarine for my 2007 project. Probably about 2m...
Before you worry too much about bouyancy, you need to go back to the proverbial drawing board and pick another radio frequency. Microwave ovens work at 2.4 GHz...
Only the submarine has to sink. A nylon line to a bouy will let you recover your valuable sub when you have those catastrophic failures during the testing...
Thanks Rune, I had already thought about that. I'm an ex Radio Engineer - VLF is out of the question - especially as I want to transmit Video... I am going to...
I am trying to avoid any form of line (once I have gone passed the testing phase...<grin> ) - they tend to get tangled and tbh, it shouldn't really be...
how about alka seltzer in a dry tank and when you want to come up you flood the tank. PLOOP PLOOP FIZZ FIZZ..... ... From: Martyn Kinder <martyn@...> ...
That's broadly the idea, although I was hoping for something more controlled. All things being equal, I will need to evacuate about 20kg of water for a full...
Another design is heavier than water. It submerges easily. Then when you're ready to come up the electric magnet releases the steel weight and the sub...
The CO2 cylinders that they sell for Seltzer spritsers and air pistols should do that trick. Or get a more heavy duty cylinder that is used on competition air...
Thanks for that, I am not too happy about leaving lumps of iron or steel behind, although I would consider this for a failsafe emergency option. I like it ...
Thanks - good suggestion I used to brew beer (scientific testing only of course) and used CO2 cylinders to pressurize the barrels. I'll pop down to my local...
Why not simply pump the ballast? Adam ... __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam...
... Need to replace the ballast water with something else? Why?? Air is compressible, one does not *NEED* to replace the ballast water with something else! A...
Dear all, Anyone here could help me to catch these papers? Sharon, E., Brandt, A., Basri, R.: Fast multiscale image segmentation. In: Proceedings of IEEE...
Ok! Why not use a high-pressure pump. The type used for inflating tyres. You have an air tank. The pump puts in water & compresses the air. So you have more...
I fail to understand the relevance of the last 2 posts to the topic of this discussion. Does this mean the discussion is closed? I would like to know more...
Probably better than dumping a bunch of Epsom salts or seltzer tablets in the water. Less likely to kill the pond. Steve Greenfield ... you're ready to come up...
Nothing, except it means the person starting the "Help!" thread did so by replying to the Einstein thread and changing the subject line. Yahoogroups puts stuff...
I am a recent college grad. I majored in business and sales, but recently have become interested in science. I'm not looking to go back to school, but I was...
... I have experience in writing the sort of software being discussed. I've glanced though some of the paper and generally found them to be an incomprehensible...
... Houses on well water have a similar device which is typically referred to as the pressure can. Inside the can is a bladder filled with air. Water is pumped...
