I have always liked Canada. If it were not for just a few laws I would gladly move there. In some ways Canada has great freedoms, in others not so. The same goes for the USA. I like the fact that most of Canada is as unspoiled as the USA once was. The USA has too damned many people.

Here I am! http://i117.photobucket.com/albums/o42/warped60120/095.jpg

BTW if the guy truly was a SEAL he was going to be offered better employment for the CO would have felt the need to see that he was given a better opportunity. You see, that is the problem, telling people you are such and such becomes offers for better jobs, people thinking the boys have let you down, that the men you served with don't give a crap, that you are telling the truth when you give your expert opinion of things. Go take lessons from a fake jumpmaster and tell me how you feel. Offer a fake D licensed guy a job at a DZ

Saying you are a SEAL teaching climbing and telling people about a myriad of other things including HALO jumps and medals awarded is an issue, a big one. If you can't see that then just go on about your business. In my case yes the guy was a fake and got called on it. Upon the request to come clean on the issue and be done with it, he then challenged the persons asking them and stated he was a real SEAL and would stomp us for questioning him. He now sees the error of his ways, maybe he will continue but he won't be working around there anymore. He will probably also be very careful of who he tells his lies and tales of daring do to.

I agree, my background in engineering has always helped me. My ability to visualize things like this has always been of great benefit. This is why we should encourage kids to be able to do such things, not everything comes from writing it on paper first.

Darwin was asleep.

Agreed, but was referring to pressure not sound.

I was speaking to the visualization of the pressure wave. " The state properties of water (temperature and pressure) and the degree of salinity also affect the speed of sound. The propagation of sound waves in sea water can be directly affected by suspensions of particulate matter that can scatter, absorb, or reflect the waves. Laboratory experiments demonstrate that distilled water—water from which salts and other suspended particles have been removed—provides a medium in which the speed of sound exceeds the speed of sound in ocean water. The difference in the speed of transmission is significant—speed in distilled water may be 20 to 30 times that of speeds found in ocean water. Because frequency and wavelength are inversely proportional characteristics of sound waves, low-frequency signals produce long sound wavelengths. These long-wavelength signals encounter fewer suspended particles as they pass through the medium and thus are not as subject to scattering, absorption, or reflection. As a result, low-frequency signals are able to travel farther without significant loss of signal strength. Naval communication systems utilize low-frequency, long-wavelength signals to enhance communications with submerged submarines. Physical Differences Produce a "Sound Channel" Within the ocean, the speed of sound varies with changes in depth that accompany normal changes in temperature and pressure. Specific combinations of temperature, pressure, and salinity may act to create shadow zones, or reflective layers, that are resistant to the propagation of sound waves. A specific set of conditions, however, also act to create a channel through which sound waves propagate at minimal speed but with minimal loss of strength. Similar to the transmission of light through fiber-optic cables, the refraction (bending) of sound waves by layers of water with varying temperature, pressure, and/or salinity allow the formation of a well-defined sound channel. Although the oceans are not uniform bodies of water—there are currents of water with dramatic variations of temperature (such as the Gulf Stream) and salinity—the speed of sound in the deeper regions of the oceans is influenced more by high pressure. Conversely, at shallower depths, temperature plays the most dominant role in governing the speed of sound. The greater the temperature of the water, the faster sound travels. Surface temperature variation can be significant with seasonal variations in the amount of sunlight (insolation) that can produce changes in near-surface temperatures that, in turn, affect the speed of sound in water near the ocean surface. When the near-surface layer is well mixed by currents and surface action, a resulting isothermal layer allows uniform propagation speeds for sound waves. Such isothermal layers are common in mid-latitude regions. The SOFAR Channel A temperature gradient exists when the temperature of the water decreases with increasing depth. The resulting thermocline shows a characteristic decrease in the speed of sound with decreasing temperature. However, at a depth of approximately 750 meters (2,460 feet), the variations in temperature become so slight that the water becomes essentially isothermal (of uniform temperature). From that point, the speed of sound is regulated more by changes in pressure that accompany the increasing depth. Because sound wave transmission speed is directly proportional to pressure, the speed of sound increases as the pressure increases with depth. Accordingly, at the interface of the thermocline and the isothermal depths, there exists a region of minimal speed of sound. This interface creates a sound "pipeline," or "deep sound channel," within the oceans that allows the transmission of low-frequency sound over thousands of kilometers. This sound fixing and ranging (SOFAR) channel was discovered in 1943 by an American team led by Maurice Ewing and J. L. Worzel, and independently by Soviet physicist Leonid Brekhovskikh. Ewing and Worzel demonstrated that the SOFAR channel was capable of transmitting the low-frequency, long-wavelength sound waves produced by an explosion near the Bahama Islands to receivers stationed near the coast of Africa. SOFAR channel depths also are a function of the depth and thickness (extent) of the thermocline. For example, SOFAR channels run nearer the surface in colder, polar seas. Temperature and pressure affect water density, and the refraction of sound waves occurs at the interface of mediums (or layers within a medium) of differing density. Because of refraction, sound waves traveling through the SOFAR channel are deflected toward a region of lower velocity. Accordingly, waves traveling upward toward the surface, where the speed of sound increases with increasing temperature, deflect downward. Waves traveling toward deeper water, where the speed of sound increases with increasing pressure, are deflected upward. Sound waves can be trapped effectively in the narrow SOFAR channel. Traveling at minimum velocity, the sound waves lose little energy, allowing the waves to propagate over distances in excess of 25,000 kilometers (15,500 miles). Prior to the widespread use of GPS (global positioning system) equipment, the SOFAR channel also was used for navigation and the location of marine craft. Some scientists hypothesize that certain species of whales utilize the SOFAR channel to communicate mating calls over long distances. Based on the known relationship of temperature changes to changes in the speed of sound, the Acoustic Thermometry of Ocean Climate (ATOC) project is attempting to provide data crucial to measurement of changes in global temperature. By measuring differences in the speed of sound transmitted over long distances (such as across the Pacific basin), data accumulated over a long timeframe should average out variations in temperature and salinity, enabling ATOC scientists to calculate changes in ocean temperature that may provide evidence related to questions regarding global warming."

Actually I just though it was cool... However it did show a similar principle with water as a medium. Salt water being far more dense than air will exhibit a similar pressure wave at a far slower speed.

What a load of crap, too bad people eat that up.

The logic of that fails. If a person never said something it is wrong to attribute it to them. People can no longer distinguish between TV shows and what has really occurred in the news. Should we judge all skydivers by the TV commercials featuring false skydivers?

Oh you just call your friends to tell them you are taking a dump.

Say "Hey, you know you want me." and arrange a booty call. It'd do you a world of good. Be good for her too, right? It cures what ails them

People remember all the parodies and insist that it was the truth, much like Sarah Palin being blamed for things said by Tina Fey.

Saw some great pics of Dan throughout the years today. Him standing next to the first fighter he had assigned to him it was an P-80 Saw a pic of him in his F-86 and a pic of him in his last plane the F-100 Super Sabre Damn what a cool guy he was and humble as well. I asked for scans of the pics and I will post them.

Well I lost another friend but he went out the way he would have wanted, alone, independent, puppy at his feet and never having spent one day sick his entire adult life. Here is a little about Dan, he was the worlds biggest joker and storyteller, people used to think he was a BS artist. The weird thing is that everything was true. He couldn't help it that he had achieved, done and seen so much in his lifetime. I am really going to miss him, he was so strong that even in his golden years he could benchpress well over 300lbs. The guy was a bear of a man, his hands were even larger than mine. He would chop wood with a small axe that huge men could not do with a splitting wedge and 20lb. sledge. The man looked like a thug but was actually a true genius.

Damn Max that is way cool. Don't be showing it off too much or all the cool kids will cut their leg off, so they can get one

I watched the video and judging by her mannerisms as well as her speech pattern I have come to the conclusion that she is both a racist and liar as well as a thief.

New Prosthesis Recycles Energy February 18th, 2010 According to an article posted on Plos One, researchers Steven H. Collins (Department of Biomechanical Engineering, Delft University of Technology, Delft, The Netherlands) and Arthur D. Kuo (Departments of Mechanical and Biomedical Engineering, University of Michigan, Ann Arbor, Michigan, United States of America) have developed a new prosthetic ankle that recycles energy through the natural gait of walking. They have mimicked the natural push-off of a human ankle and using a microprocessor to control the device, capture the energy normally dissipated by the leg. This new technology requires less than one watt. Perhaps this same technology can be used by developers of Human Exoskeletons. New Prosthetic http://www.soldiersystems.net/

hYDROCODONE aND kNOB CREEK WORKS QUITE WELL That is an awful combination The acetaminophen will kill you in a horrible way. People think there is no risk and it is a nasty way to die. You only need to overdose on it just once. Vicodin 500 has 325mg of acetaminophen. People who party with that drug take 2 or 3x the dosage that is safe. I have a standing prescription for them and I hate to take them. It is a nasty drug.

Why do you want to know... Besides, I am a pussy and I would have gotten my ass whipped if I tried.

They were idiots, to say the very least. If it were some symbol of being a devout tosser they would have known immediately
