Natural Science Forum / Physics / Relativity / September 2006Interesting idea
I am trying to understand the ideas expressed on http://www.androcles01.pwp.blueyonder.co.uk/DominoEffect.GIF but the text is too brief for me to understand. Could someone familiar with this idea please elaborate? |I am trying to understand the ideas expressed on | [quoted text clipped - 4 lines] | | idea please elaborate? You'll need to understand elementary calculus to fully understand it. Many text books are available, and also many websites. http://cs.gmu.edu/cne/modules/dau/calculus/calculus_frm.html Google hits - 5,470,000 for elementary calculus http://mathworld.wolfram.com/Derivative.html There are no shortcuts to mathematics, I'm sorry to say. Velocity is usually understood by nearly everyone in miles per hour. Travel 30 miles in 1 hour and you are travelling at 30 mph. However, you can still travel at 30 mph if you travel 1 mile in 2 minutes, or 44 feet in one second, or 4.4 feet in a tenth of a second, 5.28 inches in a hundredth of a second, 0.528" in a millisecond, and so on. This leads to the idea of instantaneous velocity. We can make the distance arbitrarily small and the time also, and as long as we keep the ratio x/t the same we have a velocity of 30 mph. Androcles.

The original link made use of the definition of the derivative of a function, and pointed out that f(x+h)-f(x) makes use of a point which is faster than light. That is the issue I wish to discuss. | And now I am lost. The original link made use of the definition of the | derivative of a function, and pointed out that f(x+h)-f(x) makes use of | a point which is faster than light. The "function" has two slopes, c and -c, neither of which are faster than light, although the slope at B is undefined. There is no "h" at tB, the time of reflection. f'(t) = [f(t+0)- f(t)]/h = 0/0. It is not possible to take a derivative at an end point or discontinuity. Einstein *could* have said c = AB(tB-tA), -c = BA/(t'A-tB), but deliberately omitted tB because he wanted to change it from tB = (t'A-tA)/2 to become tB = tau(t'A-tA)/2. For v = 0.6c, we have a round trip time t'A-tA = 20 Half of (16+4) is 16, the other half is 4.-- Einstein math. Since 8 is half of 16 tau(0) = 0, tau(4) = 8, tau(16) = 8, tau(20) = 16. This Einstein calls a "linear" function. The cuckoo misformation also includes xi(x), http://www.androcles01.pwp.blueyonder.co.uk/Smart/Smart.htm 'Really, this is what is meant by the Fourth Dimension, though some people who talk about the Fourth Dimension do not know they mean it. It is only another way of looking at Time. There is no difference between Time and any of the three dimensions of Space except that our consciousness moves along with it.' -- Herbert George Wells - "The Time Machine" - 1895. "The secret to creativity is knowing how to hide your sources." --Einstein This is the story of a scientific crime. I mean a crime committed by a scientist against fellow scientists and scholars, a betrayal of the ethics and integrity of his profession that has forever deprived mankind of fundamental information about an important area of astronomy and history. Einstein developed certain astronomical theories and discovered that they were not consistent with observation. Instead of abandoning the theories, he deliberately fabricated observations from the theories so that he could claim that the observations prove the validity of his theories. In every scientific or scholarly setting known, this practice is called fraud, and it is a crime against science and scholarship. My thanks to Sir Isaac Newton, I mean no disrespect by using his words. I have only substituted "Einstein" for "Ptolemy". | That is the issue I wish to discuss.

Turns out you are simply a troll. Go harass the religious newsgroups, it is easy to get a rise out of them. > Turns out you are simply a troll.

I do not understand what http://www.androcles01.pwp.blueyonder.co.uk/DominoEffect.GIF is purporting to demonstrate and would like to discuss this with someone. >> Turns out you are simply a troll.

It is a DIVISION BY ZERO ERROR according to Sausage Adroid. He writes c = 0/0 there...you see it? He removed other parts of the text which were all to stupid. According to Android, the proud of the Brits, relativity must be wrong because Einstein divided by zero, says Androcles the Sorcerer. According to this Crank, relativity must be wrong, because it contradicts everyday experience. HIS experience. He claims to be an engineer. A British engineer's daily experience is that everything goes broke and does not work as promised. Bad luck for him, that stigma. Don't take him too serious, he is a clown. Sometimes he is even funny. w. > It is a DIVISION BY ZERO ERROR according to Sausage Adroid. > He writes c = 0/0 there...you see it? The portion that caught my eye was the derivative. Well, so far the gentleman has made no effort to clarify his position so I am quickly losing interest. >> Turns out you are simply a troll.

Sorry ai but I can't read that GIF file. It doesn't seem to contain much more than a light clock which I have made a web page of here. http://www.geocities.com/physics_world/sr/light_clock.htm Pete > Sorry ai but I can't read that GIF file.

Don't pretend to be an imbecile trying to understand another imbecile.
