  1. Question asked - Why even have the power source (wall outlet basically) connected to the VT, and just hook up the power source up to the computer directly, Simple Answer. Wall sockets provide relatively high voltage alternating current, computers run on low voltage direct current, as do most electronic circuits. You need something to reduce the voltage (a transformer) followed by something to change the alternating supply to direct current ( a rectifier). The rectifier back in the 1960's would have used one or more vacuum tubes (thermionic diodes). With the coming of transistor technolog
  2. Thank you for giving this thread your thoughts, it is appreciated. I must think about what you say about the infinity of numbers that exist in the infinitely small space that exists between each of the infinite set of numbers. My feeling is that when it comes to plotting graphs there won't be any surprising jumps - just a continuing of a smooth transition. For example it is surprisingly easy to "show" the square root of two on a plane surface and it fits into the general scheme of things. BTW the link you gave for Cantor's Diagonal Argument took me to the wrong place, but google soon sorted t
  3. Thank you Carrock for considering my ideas concerning Fermat's last theorem. Concerning the points you raise you can plot a sine wave by dividing a straight line of numerical value 1 by any number of fractions, comprise a table of the square root of each fraction and make these the points on your graph. In theory you could use an infinite number of plots for an infinite number of fractions. You can use this data to go up and down and then down and up to produce one cycle of a sine wave. That will cover all possibilities concerning Fermat's mention of integers. I don't understand the co
  4. I don't see a problem, but perhaps the point you raise was why Fermat stipulated integers, not irrational numbers. However if you could get absolutely accurate values for e and pi then the following would, IMO, be true:- One of the sine waves to be added would peak at e times 1 (sine 0 degrees), be e times .707 at 45 degrees and e times 0 at 90 degrees. The other sine wave to be added would similarly peak at pi times 1, be pi times .707 at 45 degrees and 0 at 90 degrees. If these two are in phase and added the resultant would peak at e+pi and if one is phase shifted with respect to the
  5. Perhaps I should have realised that someone might think he had a possible solution that was 1^n +2^n=10^n! I thought the point was covered in the first line. To be clear I should have asked the reader to also satisfy themselves that in all possible candidates for A^n+B^n= C^n, C will be larger than A or B and smaller than A+B. ,
  6. Someone claims to have a whole number solution to A^n+B^n=C^n where n is greater than two. If they have the three numbers then they can form a triangle. This triangle will always have an apex (junction of A and B) which will be less than 90 degrees. Please consider whether you agree with this statement before proceeding! This triangle can be considered as a triangle of forces and from which a parallelogram of forces can be drawn. Using the parallelogram of forces both a vector diagram and a phasor diagram can be drawn and used as reliable tools for navigators and engineers of
  7. Perhaps any gap, or void that has been mentioned would be in the form of water vapour. This seems closely allied to cavitation on ship's propellers. https://www.iims.org.uk/introduction-propeller-cavitation/
  8. Can't argue with that I guess that if I got a chance to play chess against a grand master I would jump at the chance and come back for more after losing. I suppose its a question of what one finds interesting or fun
  9. That is true and also for other specific values of n. However, perhaps the source of the formula I gave might lead to a generalisation for all values of n. I admit that is unlikely but it is an interesting conundrum.
  10. I think that sometimes a journey and its byways can be as interesting as a destination never reached. Also, I feel certain that there are a number of people in the world, such as me, who although knowing they are almost certainly deluded, think that there is just a possibility that there is still to be found a much more simple way of proving Fermat's Last Theorem than that produced by Andrew Wiles'.
  11. I'm not surprised - if I have worked things out correctly then a whole number solution would lead to a whole number example of A cubed plus B cubed = C cubed. If it can be proved that there is no whole number solution then it can be concluded that there is no whole number solution to A cubed plus B cubed = C cubed.
  12. I have reason to think that if A, B and N in the following equation are positive whole numbers then there is no solution. I would like either values of A, B and N which satisfy the equation or a reason why there is no solution. If you think it looks easy then give it a go - please.
  13. Starting at a Texas University Well done my son, we're proud to see you're off to university. We've done our best to see that you have everything to see you through. You have already got a phone so there's no need to feel alone. On Facebook, Twitter and the rest are friends to help you when you're stressed. When you became a teenage buck we bought you your first pick-up truck; and in your eyes we saw the joy; a young man now, more than a boy. So now for university, here is a gift from Ma and me. A shoulder holster made to hide this deadly handgun by your side. W
  14. (2*(6-(3*2)))/ (1*(8-(4*2))) should do it or if you would prefer it to equal 3:- (3*(6-(3*2)))/(1*(8-(4*2)))
  15. Mercury must be high on the list. It is used in mercury arc rectifiers which work at high current and/or voltage levels.
