  1. Here is a 50-dimensional shape for your enjoyment
  2. I finished a drawing I've been working on for too long: A simplex is a shape made by taking all the points of a polygon and connecting them in all possible ways. It turns out that this shape is a projection of the 'pyramid' of n-1 dimensions for a polygon of n sides. This polygon has 50 sides, so I made a 49-simplex. I then copied it and connected the vertices, making it a prism. This makes it a 49-simplex prism, a shape with 50 dimensions. I think I am probably the first person to draw this shape, or at least only one of < 5. It has 100 corners and 2500 edges... Here is the 3D equivalent I'm done
  3. 16 206 389 m/s, or about 0.054 c. A 1 ton projectile (presumably enough to carry a functional, if small deathray-equipped tripod) would have an energy of 262.6 petajoules, many times more powerful than the Tunguska Event. Assuming this is a winter opposition and it happened around midnight (high angle of impact), most of the trees between Philadelphia and New York are flattened. Grover's Mill is completely destroyed, along with nearby Trenton and Princeton. Windows break in Boston and Washington. Oh, and there are many of these coming in regularly, multiple explosions of similar scale. I can only assume the astronomer was not at Princeton at the time, because he would not have survived the first impact.
  4. Huh. Is that the voice of Optimus Prime narrating?
  5. It's the easy way to feel smart and superior to others, where they may have nothing else - "Everything you have ever learned and built your world around is false. I am the only one who really knows the truth. I am smart, and you all are so dumb you are blind to the obvious." It's really more of a psychological and social thing, after they ignore the entire natural world. And that is exactly what they do - they ignore, and when presented with evidence that is given by a personal experience or the Earth itself, they skip over it and refuse to acknowledge it, and bring the conversation back to how "you are being brainwashed to NOT investigate." (That is a real quote.) Even though, of course, the Earth itself never lies.
  6. A maglev might be of use on the Moon, but not on Earth. The atmosphere is too thick - in order to escape it from very low, your ship would burn like a meteor, and at similar speed. To build the rail above the atmosphere where it could actually be used would require a superstructure magnitudes bigger than anything we can actually construct - there are no materials we have which could do it. Remember, our largest spire is only 0.8 km tall. By the way, recall the instance of a nuclear bomb that was detonated below ground and launched a manhole cover into the air at 60 kilometers per second. The manhole cover is thought to have immediately disintegrated due to the immense force and heat of the air, failing to leave the atmosphere.
  7. I was going to do homework tonight but migraine was a deadly lazer...Luckily I was able to make it last only the evening rather than the typical full rotation...I guess my power over them is growing somewhat.
  8. That's a great photo. It would make a wonderful oil painting.
  9. Gets a pendulum watch. Inserts kerosene.
  10. Maybe the first ones wouldn't do it entirely on their own. The very first humans might have to build their return journey...a little morbid, but it might be one of the things Elon meant by "There's a good chance you'll die".
  11. I only got ONE thing of ketchup for my chicken...it's not enough! What an outrage! I am slightly disheveled over this.
  12. The Sun is probably almost the whitest star.
  13. Ganondorf Fun fact, Africa is often defined as the stationary reference in continental drift.
  14. Thanks, I tried to make it feel very empty and quiet.
  15. It's faster to make left turns in the Southern hemisphere instead of right turns because of the Coriolis force.
