    Is mantle convection theory as good as we can get? Can it explain the variation in the world's divergent plate boundaries? The depth of the Mariana trench? The Basin and Range area? The San Andres fault? Current and past mountain building mechanics?

    Please visit my "Plate Tectonic Mechanism?" thread in speculations and tell me what you think.

    http://www.scienceforums.net/topic/73730-plate-tectonic-mechanism/

    Is it time for a new model of plate tectonics?

    I have been quite busy writing a hypothesis concerning the thermal heating of the planets that possess magnetic fields and the several moons that exhibit the early development of these electro-magnetic phenomena that in the Earth's case I believe drive the various geologic processes that are currently observed and debated.

    You can view this work;

  1. From Endy's last link was this one to the manufacturers site; http://www.omgroofing.com/ PRODUCT DESCRIPTION "The OMG Hercules-Plus RetroDrain features the OMG vortex breaker technology integrated into the cast aluminum strainer dome. With vortex breaker technology, the Hercules-Plus can provide up to 2.5 times greater water flow, compared to the existing Hercules drain, which means that water and excessive weight can leave the roof quickly. In addition to faster water flow off the roof, the vortex breaker can greatly reduce "chugging" which can damage plumbing systems."
  2. From listening to both J.C. and studiot's opinions; In the states, and I assume where you folks are, both ends of these systems are open to the same atmospheres, and the pressures on both the ends are of little difference to each other. As I said earlier the waters cohesion forms and holds the vortex that stretches out until it collapses. But the air can and is coming out the top until the water depth/volume increases to the point the vortex completely forms at which time the atmosphere is drawn into the vortex and the air flow is only downward into the pipe. But the water's cohesion
  3. Hello psyclones, I've seen a few different sizes of roof drains in action, they start to swirl on their own when the water overwhelms the drain diameter and I believe this is simply the cohesion of the water responding to the effect of gravity, the water acts in almost an elastic manner. Sometimes if the depth of the water is just right in relation to the pipe diameter you will see a oscillating cycle where the velocity increases and pulls the surface down until some air is pulled into the vortex which then suddenly slows the velocity and closes the vortex, then the cycle repeats again an
  4. I would assume it is a type of bearing that is used in high speed conveyors in factories or bottling plants and the like, where the maintenance personnel could either visually, audibly or even use a laser temperature probe to identify a failing bearing that could then be easily replaced because all they had to do is remove a locking tab and slide the bearing off the shaft. The "staple" as you call it, is the same idea as a piece of key stock fitted to a keyway, but those are usually on the shaft and the inside bearing race. If there was a tab holding the bearing then those "legs" on the staple
  5. Interesting thing about LED lights is when we started installing them in signs I noticed that when I took a digital completion photo they had a 3 to 1 chance of appearing to be non-illuminated due to the shutter speed catching the power’s frequency out of phase. I think your camera sensor though, is picking up a reflection of its own infrared sensor or some other aspect inside the camera past the lens, sort of like the headlight beam is bouncing off one of the receptors (infrared ?) and then reflecting back to them off the backside of the lens and maybe to the primary. I would l
  6. But is it really a "214"? Our brains tend to mislead us in the most important details. Is there a part number on the mowers bulb assembly, reflector, or plastic cover? Same for the backside of the camera's dust cover or the camera's surfaces behind that cover? The other posters are pointing you to the idea that those lights are causing a projection or reflection into or from the inside of either the lights or the camera. Wouldn't it be interesting if the electrical suppling the lighting to the headlights was at a frequency that made the lights interact with the infrared sensor's frequency
  7. Asking a question! great idea! I passed on this yesterday due to that no guessing request. You are on the right track for sure. Nice observation. What is interesting also is that they each have the same offset to the right in relation to the headlight directly below them. To bad we're not allowed to guess what is causing this. Those cameras have a hinged cover with a clear plastic window to keep dirt and dust off the lights and sensor but probably not the lens itself but I could be wrong. I wondered if the cover could be slightly ajar.
  8. It is important for you to first consider that many cultures with primitive religious or cultural development both now and in the past have concluded a similar assumption; in that their world and the objects in the sky are all sentient beings controlling some aspect of their lives. The Mother Earth and a particular celestial Father (Sun, Moon, Jupiter, etc. ) of one type or another, are some of the oldest and most often repeated primitive ideas regarding creation that humans have conceived to explain their surroundings and by simple extrapolations their existence. We have a built in bias towa
  9. I hope you will find someone with a rock saw to open it up for you. I've seen a few hammer and chisel attempts that were regrettable with what would have been a display of spectacular crystals being smashed to bits. I've also used my wet tile saw on some smaller examples with acceptable results.
  10. The one defining characteristic of this Flat Earth group of individuals is that they are made up, most certainly, almost entirely of the male half of the population. And that being said, explains much of the observed results;

    SEASON"S GREETINGS

    Merry Christmas to all, I was going to post something here in the lounge and saw this thread, I hope you don't mined me putting it here instead. Does anyone else have a certain day that comes around every year that makes you wish you could do it over again? That one day a year that makes you feel regret that you didn’t do something to help someone you didn’t know, something that may have completely changed their life going forward. Well, my “do over day” was Christmas Eve 1993. We were working a half day installing an electric sign at a store in a small shopping center in a rather s
  13. Just an observation looking back some 40 years ago when I was a teen and such things seemed important, all it took was one socially respected observer to proclaim any cosmetically challenged person as being a "Hot guy" or a "Foxy chick" and that persons image to those in the vicinity was miraculously changed.

    American Cheese

    These folks in Thorp, Wisconsin are getting a great deal of attention but I haven't had a chance to try some of it. https://www.mariekegouda.com/ And this is an interesting profile about these transplanted Dutch family cheese makers and how they began their award winning enterprise. https://www.viroquafood.coop/viroqua-food-coop-blog/bid/207372/p6-profile-holland-s-family-cheese-maker-of-marieke-s-gouda There is also a growing interest in my home state of Oregon regarding artisan cheese making that is similar to the craft brewing phenomena that has its roots here in Oregon
  15. Big celebration for our family, we are joyously expecting our first grandchild!  My daughter and her hubby have been trying for almost five years. The hubby's brother is a video/photographer and did this for them. That is his little boy on the slide. I'll take one just like him! :)  https://www.youtube.com/watch?v=Au_NzCb13DQ
