@OP, I would be very grateful if you explain Godel's Incompleteness Theorem in simple English and in a very easy to understand manner.

Yes, the gyroscopic effect and the centrifugal force acting against the 'lean' of the bicycle are zero if it is motionless.

I have always been under the impression that I totally understood the mechanics working behind the stability of a bicycle i.e. i) the gyroscopic effect of the spinning wheel ii) weight of cycle and rider and iii) the centrifugal force acting on the CG when the bicycle follows a curve path. If...

I recently followed The American Society Of Civil Engineers page in Facebook. I found that they are using only Imperial Units. Now, don't get me wrong. I have nothing against the Imperial Unit whatsoever :smile: On the contrary, as a civil engineer myself I applaud the American civil engineers...

This definitely is the height of geekiness :smile: :thumbs:

What about in the schools and colleges? Which system is used for teaching? On a side note, even though we use the Metric System, we use feet-inches for measuring the height of a person. Curiously, in the US where the Imperial System is used, cm seems to be a popular unit for...

I always used to wonder why the Imperial System is always included in AutoCAD and was surprised to learn that Metric System is not used in the US. This must be inconvenient IMO, especially in science and engineering. Personally, I think Metric System is more convenient for science and...

Could you show me the process please and how ##\frac{1}{1}## is to be onverted back to 0.(9), if its not too much trouble :redface:

Right, and IMHO, the best argument for demonstrating that 0.(9) and 1 are exactly equal :approve:

How 0.(9) should be converted to fraction?

I had long been under the impression that I understood the principles of winged flight. We were taught early in school that the lift generated in the airplanes' wings is due to Bernoulli's Principle. Last week as I was contemplating sustained inverted flight of jet fighters it occurs to me...

Thank you guys for your insights, we managed to resolve the question. When we are talking about classical physics, I think we sometimes tend to grab ideas from Relativity and Quantum Mechanics and get confused and this seems to be the root of the problem.

Hi. This is my first post here. In one of our science groups in Facebook, a member is asking about a case where r=0 in Newton's Equation F=G(Mm/r^2) The best i could do was to state that there cannot be two point masses with a distance r=0 between them. He seems to accept my explanation but...
