Your flaws are my pain April 13, 2011 Today, there is increasing exposure of individuals to a public audience. Television shows and the internet provide platforms for this and, at times, allow observing others' flaws and norm transgressions. Regardless of whether the person observed realizes their ...

Good to be back. Welcome back ! I had a moment of humor as I finished reading your post. A thought popped into mind of that scruffy, ex-drunk pilot in Independence Day who took down the alien ship, immediately after saying: "I'm baaa ack". I had to flick my vision to rereading the first w...

Tarsier79 Our discussion shows that I violated my own rules. I didn't analyze your simulation completely, but just jumped on a couple of points of discussion, sorry. My rules are to remind myself to think clearly and carefully and tell myself that as a non-engineer and non-physicist, design what you...

Edit: original text removed, not sufficiently on topic. Tarsier79 I will be happy to be wrong if someone else produces a build... I don't think it is necessary to produce a build. I think I can comment based on pure observation of the second part of the simulation titled "Elasticity 1". Fo...

Maybe I'll get laughed at for this, I'll just try to laugh along too. I prefer to think about focused or directed momentum in a rotating system. Is focused or directionalized (my slang) momentum important? Use as a mental picture a K.O. punch. The boxer has focused energy (momentum) into a roundhous...

Yes, Newton was certainly correct for the time when he proposed the 2nd law and for the most part humanity agrees. Frankly, I am a believer, all Newton's Laws are correct as stated and inviolate. Nevertheless, it is possible to achieve a higher CM in a system. What is sometimes forgotten, and we hav...

Pendulum Demonstrations (14 links in 1) According to a 1999 Gallup poll, about four out of five Americans (79%) correctly respond that the earth revolves around the sun, while 18% say it is the other way around. Oh shit, those 18% get to vote! By the way, the results in European countries are in the...

Nick, I have read some of your posts. I am impressed with your understanding. That said, I am mistaken in the manner in which I interpreted and answered your question. I do not know if you mean a freely rotating system or a system constrained. Therefore, another attempt. I am still learning, so plea...

Is there any documented precedent of one of these devices being started by lifting the bob though "x" degrees of an arc equating to a meaurable force , and ending it's oscillating, bobbing or swinging in it's natural keel position (that from which it started before the lift and release of...

Unbalanced, great find. Thanks for the post. I hope many investment groups and corporations have taken subjects like this seriously or we are all in trouble. About the gyro in a navigation system: Edit: Add "in a navigation system" The type of spinning gyroscope, sitting on gimbals, and us...

If you work in that lab, you might not want to become attached, name those beetles or take them as pets. What would DARPA plan to do with those beetles? Use them as guidance for something that goes boom?

path_finder, The male red Chinese fish, also known as Asian arowana are endangered under the Endangered Species Act, it is highly illegal to own them. Contact the Department of Interior immediatly. This picture is surely fake! The mode of reproduction of these fish is almost certainly ovopartity. Th...

.....if we try to imagine a gravity machine(motor),between the six types of known simple machines: -inclined plane family (inclined plane,wedge,screw). -lever family (lever,wheel and axle,pulley). So...what "family"!? All the best! / Alex Alex, I don't think gravity can be easily, nor eff...

Chris, there is during the slippage of liquid a transfer of center of gravity from one side to the other. But as you agree, the center of mass, or average height of mass is identical in all three situations. Therefore any height gained by an object acted upon by the tilting tank is gain of com ? Whi...

For your interest, using ropes, levers, and ratchet:
