We know that distant galaxies (which are expanding) are sometimes expanding at rates that do not conform with our known theories and formulas developed by our own observations of gravity. Einstein's theory is of course at the forefront of this conundrum.
To explain it some believe that we...
Jim, hi, yes indeed a practical matter. And yup, I have replaced a fewer alternator brushes too. That was a practical matter then too because in those days alternators were not as disposable as many are today. They were designed to be rebuilt and at a less expensive alternative (pardon the...
Thanks for that vote of confidence. In my opinion it only requires being able to see the forest without having all the darned trees in the way. I understand your weight ratios and bearing problems, but there are many ways to skin a cat. Simplicity, simplicity, simplicity. Electricity is...
Couldn't have been said better! I'm guessing you are pretty good at philosophy also... Looking into a very narrow box of known data discounts vision for the unknown, I think. To that end I think it narrows the perspective so greatly that even the simplest ideas become overlooked.
I may...
Thank you. Your help has probably saved a good deal of time on my project. Superconductors would be perfect for my experiment, but since the project involves increasing the efficiency of generating alternating current I fear the added cost of cooling the substrate would be contrary to the...
Thank you for letting me monopolize your time. You are certainly kind and I thank you for sharing your wealth of knowledge. It seems like the deeper the answers get the more questions I have. I apologize for that.
I believe all superconductors require cooling to around -400 F, no...
Thank you for that info. I think this info will help me significantly. I have a question about your response on insulating magnetic fields with substances such as mumetal. (Great tip btw. Thank you for that.) It seems like such substances are deterring the magnetic field rather than soaking...
I'm attempting to build an alternating current electromagnetic coil and want to maximize its potential field. My initial query was to find the very best core material for the electromagnet. I found an older post (2005) on the subject and saw some very interesting answers there. Being new here...
