I have devised a photonic motor just in case people switch from electricity to light. It would work like a radiometer, except it would not need a vacuum. It would have about 6 vanes, which would be colored black. A laser would fire a laser beam at the vanes, which would absorb the photons and cause the vanes to rotate clockwise. For a faster speed, the vanes could be colored white, which when struck by a laser beam, would reflect the light back. When the laser light hits the vanes, the vanes would absorb the momentum of the light and be pushed clockwise. When the light is reflected, the reaction with the vane would push the vane clockwise, making it turn twice as fast as the motor with the black vanes. That's all I have to say on the subject.

Fusion may occur if you have deuterium (an isotope of hydrogen with 1 proton and 1 neutron atoms colliding at speeds near the speed of light from opposite directions in a cyclotron (a circular particle accelerator). Here are the equations: \[ \text {Kinetic Energy} E_{k1}=\frac {1}{2}mv^2, E_{k2}=\frac{1}{2}mv^2\\ \text {Since the atoms are travelling in opposite directions, total energy} E_T=E_{k1}+E_{k2}\\ =\frac{1}{2}mv^2+\frac{1}{2}mv^2=mv^2.\\ \text{If } v \rightarrow c, \text{then total energy } E=mc^2,\\ \text{which implies that matter is being converted into energy.}\\ \text{Sorry that everything is centered. I couldn't figure out how to end or add a line.} \]

That makes sense, Swansont. Thank you for your reply. If not the spiral pattern, they could be using a zigzag pattern - they could go from left to right down a row of flowers, then right to left down the next row of flowers, left to right down the next row of flowers, etc. A good way to find out what pattern they are using is to plot their paths on polar graph paper, which uses (r,theta) notation, where r is the radius and theta is the angle.

Bees are probably using a simple algorithm to solve the travelling salesman problem. We know that when bees get back to the hive after discovering a new group of flowers, they do a little dance. The length of the dance represents the distance to the group of flowers, and the direction they are pointing indicates the direction to the group of flowers. The bees could be using a spiral pattern to find the flowers. They would start at the middle group of flowers, and work their way outwards in a spiral pattern. That's just a guess. They could be using some other algorithm.

Well, we know that E=hf, so the greater the frequency, the greater the energy. If you wanted to stay within the visible spectrum, you would chose ultraviolet light. Beyond that, there is X-rays and gamma rays, but I don't know if the fiber optic cable could withstand such high energies, or if the cable could contain these types of rays. Instead of using solar cells, which have very low efficiency, to change light into electricity, the light could bounce off mirrors arranged at 45 degree angles, and the light could circulate around a square made up of 4 of these mirrors, which would constitute a photonic capacitor. The light could be channeled into a photonic pumped laser which would use 2 different gases to keep the laser operating continuously. The laser beam could be modified for use in monitors and TV sets, which would use part of the laser beam for power.

I have a brilliant idea: We can use lasers to transport energy instead of electricity. All we need are two fiber optic cables: The first to transport continuous laser light from the origin to the destination, and the second to transport information, such as from TV stations. If we develop optical computers, we wouldn't have to change the light into electricity.

Teleportation is moving from a certain location to another without travelling through the intervening normal space. Star Trek depicts teleportation as entering a transporter that uses a computer to scan poeple or objects atom by atom or molecule by molecule, then teleporting the atoms or molecules to a different location. This would be difficult to do by a computer because poeple or objects have an extremely large number of atoms or molecules. An alternative would be to travel through the 5th dimension or higher, also known as hyperspace, possibly by using wormholes. I envision it as using a belt with a lighted buckle like the neural neutralizers worn by the Kelvins on Star Trek. This assumes that hyperspace exists or can be created, and that we can gain access to it. If teleporatation were possible, it would make all other forms of transportation obsolete. The person or object would simply disappear from its current location and reappear in a different location. It might even make travel to different planets possible.

The digits 0 to 9 all appear with the same frequency in numbers, so you could say that all the digits are equally important. Similarly, in the game of baccarat, only the digits 0 to 9 are treated as important. What if you wanted to prove that all the digits are important, using mathematics? You could make lists of digits and show that they are important. Perfect squares: 0,1,4,9 Square roots of perfect squares: 2,3 Prime numbers: 2,3,5,7 Fibonacci sequence: 1,2,3,5,8 Honeycomb structure: 6 Number of sides on a die: 6 Number with the most combinations on 2 dice: 7 Perfect cubes: 8 Next, make a frequency chart, with digit followed by number of times mentioned: 0: 1 1: 2 2: 3 3: 3 4: 1 5: 2 6: 2 7: 2 8: 2 9: 1 Therefore, there are 3 digits with importance 1, 5 digits with importance 2, and 2 digits with importance 3.

Mathematically writing about hyperspace: Locating an object in 3-space requires 3 coordinates: (x,y,z). Locating an object in 4-space requires 4 coordinates: (x,y,z,t), where t stands for time. Locating an object in 5-space requires 5 coordinates: (x,y,z,t,h), where h stands for hyperspace. This doesn't tell us if hyperspace exists or not, and it doesn't tell us how to gain access to it. Since it is a jump drive that uses hyperspace, I think we should call it hyperdrive.

I've been reading and thinking about teleportation. Instead of using supercomputers and quantum entanglement to scan all 10^28 atoms in the human body, which would take a very long time, what if there were a 4th spacial dimension, let's call it hyperspace, that we had access to. Then all we would have to do is enter hyperspace with a spaceship, fly to an exit point, then enter a certain place in 3-d space. The process would take almost 0 time, and we could still call it jump drive. The difficult part is gaining access to hyperspace.

Teleportation is transporting an object from place to place without traveling through normal space. So if you transport an object through a brick wall to the other side, that's teleportation. Since it doesn't travel through normal space, it should take 0 time. If you attach a teleport device to a spaceship, you should be able to jump from place to place in the universe, and it should take 0 time, just like in Isaac Asimov's book, 'The Stars, Like Dust'.

PHOLEDs (short for PHOsphorescent Light Emitting Diodes) are light sources that are almost 100% efficient. Would it be possible to create solar cells that use a similar principle, but in reverse, so that they too would be almost 100% efficient?

What I meant was, would it be possible to construct a device which would convert up to 100% of white light into electricity, similar to a solar cell, however would not use the exact same principle as a PHOLED?

As you may know, PHOLEDs, which is short form for PHosphorescent Organic Light Emitting Diodes, can convert up to 100% of electricity into white light. Would it be possible to run the reaction in reverse, like in a solar cell, so that up to 100% of white light is converted into electricity?

It could be that we sleep to conserve energy. Our ancestors didn't have lights (except when they discovered fire), so they couldn't do anything at night. Maybe to conserve energy, they went to sleep. That is why people who don't sleep very much at night need to eat more food to replace the energy they lost because they weren't asleep.

We now have 3D TV's that don't require 3D glasses. Is it possible to make TV's with 3D sound that only comes from it's own speakers (that is, it doesn't require external speakers) so that different sounds will seem to come from different locations in the 3D volume?

Since neutron stars contain only neutrons, which are electrically neutral, the large magnetic field strength cannot be due to moving electric charges. Instead, it must be caused by the large mass and large rotational velocity of the star. If rotating gravitational fields cause magnetic fields, that would be the link between gravity and electromagnetism. From B, m, and [math]\omega[/math], the magnetic field constant [math]k_B[/math] can be calculated.

Note that the Commodore 64 can only display eight decimal places and the basic commands can only see eight decimal places. The C64 is capable of analyzing nine decimal places, however at ten decimal places, an infinity is produced and no further decimal evaluation is possible. So for equation iterations that produce more decimal places than nine, are incapable of being further evaluated by the Commodore 64. Note that ^ is code for and ~ is code for ^ under the VICE emulator copy/paste function. 10 clr 20 n1 = 12 30 v1 = val(mid$(str$(^),n1,1)) 40 print v1:print ^ 50 pi = ^ 60 n2 = 0:e1 = -9 70 v1 = val(mid$(str$(pi),11,1)) 80 if v1 = 7 then goto 110 90 pi = pi + 10~(e1):n2 = n2 + 1 100 goto 70 110 print n2""pi 120 end What is this program supposed to accomplish?

Thank you for the information, Orion1. I might need it someday.

That is complete nonsense. Anybody else who has something worthwhile to say about post #107, please do so.

Here's a pi formula I found in 'A History of Pi' by Petr Beckmann, top of p. 185: [math]\pi[/math] = 24 arctan(1/8)+8 arctan(1/57)+4 arctan(1/239) Here's the program, typed on a C64 computer, that goes with it: 10 REM PI24ATN8 FROM 'A HISTORY OF PI' 20 REM TOP OF PAGE 185 30 PI=24*ATN(1/8)+8*ATN(1/57)+4*ATN(1/239) 40 PRINT 50 PRINT "PI =";PI

I finally got the C64 emulator to work, after I found out that it uses the same keyboard configuration as an actual C64. Pi 16K8 Formula: Here is a perfect pi formula that I have found. It converges on pi very quickly, and doesn't need to use factorials. Here is the program to go with the formula. I wrote it in Structured BASIC on my C64 computer. You can use values of k from 0 to 31 on the C64 without getting an error. I got rid of the unnecessary brackets in line 340. It is a very short program. 100 REM PI 16K8 120 REM FROM PI FORMULA USING 16^K AND 8 140 REM 160 CALL MAIN 180 END 200 : 220 PROC MAIN 240 .....L=10 260 .....REM PRINT "A",,"S" 280 .....K=-1 300 .....LOOP 320 ..........K=K+1 340 ..........A=1/(16^K)*(4/(8*K+1)-2/(8*K+4)-1/(8*K+5)-1/(8*K+6)) 360 ..........S=S+A 380 ..........REM PRINT A,S 400 .....UNTIL K=L 420 .....PI=S 440 .....PRINT:PRINT "PI =";PI 460 ENDPROC

I downloaded WinVICE, and I found the Commodore 64 screen, but I couldn't get it to work properly. Besides, why would I need a C64 emulator when I have an actual C64? Thank you for your concern.
