    Extraterrestrial impact caused Younger Dryas?

    Ok Buchanon et al. disagrees with Firestone et al. I am not qualified to be the arbiter in that debate. I'm an old ex GI who still knows his place in the firing line. I ‘m not sure how it fits into all of the different scientists pet theories, or research. I think, after all of the fur...

    Extraterrestrial impact caused Younger Dryas?

    Ok, I read the mans paper. I don't agree. Time will tell

    Extraterrestrial impact caused Younger Dryas?

    Thank you for your opinion. In fact I see no evidence of any uplift whatsoever. I do, however, see compelling visual evidence of massive surface compression shock waves. That, judging by their dimensions, are from a surface explosion which would have been large enough to devastate most of the...

    Extraterrestrial impact caused Younger Dryas?

    I don't buy it. I expect those features to be evident in the precambrian basement structure like everywhere else on Earth a continental collision has occurred. Whenever I hear the words "Most geologists agree that those rings are the result of an ancient tectonic collision." it gives me...

    Extraterrestrial impact caused Younger Dryas?

    Every other arc shaped landform on Earth that is the product of such a continental collision; The Hymalayas, island arks like the Aleutians, the roots go all the way down through the basement bedrock beneath. But on a map available from the USGS, and Titled Preliminary Precambrian Basement...

    Extraterrestrial impact caused Younger Dryas?

    Look I am a layman. nothing more. If I found a dinosaur bone I'd tell a paleontologist about it. If he wanted me to give a long explanation of why I think it's dinosaur bone. I'd walk away and tell someone else. As for how I can know what the ground looks like after a large explosion. Or...

    Extraterrestrial impact caused Younger Dryas?

    In the steel industry a high energy plasma cutting machine called a burn table makes a very distintive mark in the steel. Called a plasma burn, or a burn caused by high energy plasma. Very different from a simple oxygen breathing fuel burning fire. Here's a link to describe the equipment...

    Extraterrestrial impact caused Younger Dryas?

    If you had read the thing and the refernces included you may have noticed that I called the epicenter of the blast structure a plasma burn. There is a certain high temp. implication in that word don't you think? And in fact the only reason the site is worthy of any note at all is because it...

    Any plausable scientific explaination for the temperature rise in western U.S.?

    I grew up there. Sounds pretty normal to me. "I'm dreaming of a warm Christmas. Just like the ones I used to know." You're making me homesick.

    Increase hp for a diesel engine

    I keep getting stuck on the question of why you are willing to go to the trouble and expence of boreing the cylinders and changing the pistons when a turbocharger will get you there cheaper and easier. And probably without needing to pull the engine out of the vehicle.

    Ideal heat exchange for welding cooler?

    If you can figure out a way to build a transformer that will give you the necessary energy at the torch head without generating all that waste heat, now that would be something. The trouble, is that transformers for welding machines haven''t seen much change since Edison and Tesla.

    Extraterrestrial impact caused Younger Dryas?

    Is this the YD impact site? I am admittedly over my head here but this thing seems to be beyond anything old school geology can describe. Or even acknowledge as possible. It is my hope that someone here might take a look at it while geology waits in the hall...

    Extraterrestrial impact caused Younger Dryas?

    Sorry I didn't intend to hijack this thread. But I've been studying these two papers for weeks. Evidence for an extraterrestrial impact 12,900 years ago that contributed to the megafaunal extinctions and the Younger Dryas cooling http://tsun.sscc.ru/hiwg/Activity/Firestone+25_2007.pdf...

    Question about centre of mass and load centre of gravity

    Ask a truck driver. It won't have much effect on acceleration. But control during rapid changes in direction can get a little unpredictable.

    Why do engineers need mathematics?

    As a welding inspector in heavy construction who has to work closely with the engineers I am reminded daily that without a good math tool to communicate with even some of us grunts would be lost. Asking why an engineer needs math is like asking why your gramma needs fruit to make a pie.
