  1. What sort of speeds could you get out of a computer that somehow used 4D calculations as a sort of "thinking space" to become more efficient?
  2. Exactly. It incudes the water so the water has an effect on it. It's simple physics
  3. Ok what I believe is happening is the water acts upon the boat which pulls the anchor. The anchor pulls the Earth. Now due to the huge difference in mass noone would notice the effect of the Earth being pulled but effectively the kinetic energy lost by the water would be gained by the Earth
  4. Hmm boiling sulphuric acid. I remember a day back at college when I decided to leave a beaker of sulphuric acid over a bunsen. Ended in the floor being evacuated for half an hour while the fumes cleared...
  5. Here's a table attatched. It shows part of a bigger table showing the properties of shapes in other dimensions ezspreds1.doc
  6. Cheers that helped a bunch and now I know that what I was doing was actually relevant to something. After a bit of searching I did find the 4-simplex referred to as a "Pentachoron" but I wasn't sure if it was just made up for that one example. For now I'm using a simple logical way of naming them relating to the number of points and their maximum dimension. The names I used of the "Simplexes" for each dimension are as follows: Pentatetron - 5 Points, 4 Dimensions Hexapentons - 6 Points, 5 Dimensions Heptahexons - 7 Points, 6 Dimensions Octoheptons - 8 Points, 7 Dimensions Nonoctons - 9 P
  7. I'm doing a little project at the moment to do with how triangles relate to tetrahedrons and I have some interesting results which have allowed me to calculate what the 4D version would look like. I Made a simple model to test and it worked out right. The only problem now is that none of the shapes I've found have names as far as I know. Is there a name for a 4D shape made from 5 tetrahedrons? It also has 10 faces and 10 edges if that helps. Theres a 5D shape too consisting of 15 tetrahedrons (or 6 of the 4D shapes). Thanks if anyone knows.
  8. Thought I'd add that looking at a 4D shape in 3D is like trying to see a picture of a 3D shape drawn on a piece of paper. Obviously it isn't 3D but you can make the picture 'pop out' of the page with your mind. To understand 4D you have to view the 3D representation from all sides and then 'pop it out' in your mind. Hard to explain really but after looking at the model I found it quite easy.
  9. Ok forget the title for now obviously it's leading people away from what I actually did. I was just saying that it's easier to investigate triangles and tetrahedrons than squares and cubes. About the 4D shape, I made it, looked at it and with a little thinking it's not too hard to comprehend how it would work
  10. Ok, this might take a couple of replies for me to put this in a way people can understand but here's a first shot at it. Last night I was about to go to sleep when I had a strange thought - Why do people view the universe as three perpendicular vectors (up/down, left/right, back/forth). Also similarly the 2D universe would be viewed and measured according to a square grid. But why cubes and squares? Sure they seem an obvious way to look at things with the nice right angles but when trying to link the 2D to the 3D it makes things a lot more complex. For example: Take a square. Simple 2D object
  11. I'm not saying we're going to try to destroy the planet, just that if it came down to it we wouldn't go without a fight
  12. Ha I could do that with just a box of matches - no need for gene modification
  13. So in a sense you'd have to have genetically modified 'little green men'. Hmm sounds familiar. Well they'd be slow due to the lack of energy (notice how plants don't actually do much?) but if they were little (maximise 'surface area:volume' ratio) and green (to photosynthesise) then you could have men. Well men with tough skin who moved very little and didn't think much.
  14. I figure if the human population does go extinct then so will nearly everything else. At the moment we can 'care' for the environment but if it got to the point where it was either save a species from extinction and die ourselves or shoot it and eat it then i think most people would value their own life over the suvival of an entire species. The same with trees. If you were next to the last forest on earth and it was freezing cold but you knew you could start a fire with the wood from the forest then you would go cut down the tree if it was your only source ofheat. Look on this as a generalisa
  15. I know it would be extremely difficult in practice if not impossible but could an animal (in theory) be modified to breathe fire as an attack or defence? If the animal could be modified to produce a flammable organic liquid in a gland in its mouth and have an 'ignition spark' (generated in a similar way to how the electric eel makes electricity) at the opening of its mouth, then could it not create an aerosol of fuel and ignite it when provoked?
