Hahahaha. Yes the question of what is "nothing" is something programmers often ask. http://c2.com/cgi/wiki?NothingIsAnything" p.s. if there is "no nothing" then how do you define "no". No is just another word for nothing. Double none and double nuttin!

I don't think it is about what is better in all cases. For example blue eyes and blonde hair in northern climates I am not convinced is because of it being better for sunlight. Otherwise people in Greenland would be blonde with blue eyes since those people up there would choose partners with...

Old post but good question. What all the teachers, books, and websites fail to clearly explain is that the bourdon tube is just a special balloon. The bourdon tube becomes larger in volume when pressure is applied inside. Flow occurs into the gauge tube. Volume is lost from what you were...

Because springs have a solid shape and are easier to install/swap with existing technologies in place.. for example springs in the head under camshaft, springs at the back of the car for suspension. Shocks that have air in them tend to leak and get worse over time. Well the idea of filling...

I was thinking not of cooling the springs but filling the springs with different pressures, to change the effects of the spring in real time - therefore allowing the spring to become softer or harder without the springs having to be changed. However I do not quite understand what all would...

I thought a cork squeezed into a wine bottle would contract? It just changes in length and no shrinkage? Or some air bubbles inside the cork get compressed?

Apparently the reason pipes or Bourdon gauge tubes straighten is because of P=F/A where the inside of the circular tube is a smaller area and the outside is larger. F=P*A, and with a larger area we have more force winning the battle. Vacuum (well actually the positive air pressure outside the...

Was thinking of something that doesn't exist today in our technology.. liquid filled hollow "vein" springs. Wonder what happens when a spring is a vein and filled with different fluids (gases, liquids, gels, etc) to get different effects than a regular solid core spring. Could be useful in the...

Well the pipe doesn't have to be "permanently" deformed if one uses the right material - but in my original post I implied permanent deformity for the example I guess. p.s. with Schrader gauges I believe they have a bleeding function to reset the gauge whereas a Bourden measures the real time...

Oh boy, I have just reinvented the Bourdon-tube pressure gauge. Still questions though. Would like to know whether or not the tube in his gauge expands so the internal hollow volume increases, or does it just deform to a new elongated shape (volume the same - just reshaped)? Example: when an a...

If a soft malleable metal pipe has a bend in it and is then pumped up with high internal static pressure, would this soft metal pipe seek to straighten out or would it simply remain in its bent shape due to pressure acting in many directions. I wonder if the most natural position of a pipe is...

Springs deform and basically change shape through atom rearrangement, but I wonder if the actual metal volume changes? Some of the atoms are pulled apart on the outer edges of the spring, while some of the atoms are rammed closer together on the inner portion. The total volume is conserved, or...

Yes this helps, thank you. That would be a simple practical solution. In that case gravity potential is used to store the energy.. I wonder if another potential could be used if they did not have that option. I am thinking that somehow the hidden elasticity of the molecules in a liquid can be...

Physics books and websites are full of Ideal Gas info and solutions when it comes to relating pressure, volume, and temperature. How about liquids? And solids? For example let us say a liquid in a horizontal pipe is under double the static pressure than it was originally. By static pressure I...

I will try make one soon, maybe even an animated drawing showing how a machine could work based on it. First I am performing some experiments to verify what actually happens in nature with the balloon. If I make a machine drawing up and it is all based on assumptions and bad science, it would...
