  1. Lets say we witness the twin paradox in real life without any knowledge of relativity. On Earth we see the astronaught twin climb out of his spacecraft considerably younger than his brother and both the clock on the ground and the one in the spaceship show different times.

     

    With no knowledge of relativity at all - how does one explain what has happened to a group of laymen onlookers?

     

    The only explanation I can think of is that (1) the astronaught has spent his time in space in slow motion

     

    (2) the difference in clock times is due to time and reality slowing down on the spaceship.

     

    This is fact and reality surely - something that overrides everything else for the layman! Any other answer would seem like magic to them.

     

    Once this fact is established then one can go into the realms of relativity theory

     

    Will anyone agree that from a FOR from the spaceship (1) The astronaught has spent his time in space in slow motion and (2) the difference in clock times is due

    to time and reality slowing down on the spaceship?

     

    Human brains have been educated to accept certain things without question and to think a certain way- in the box so to speak. What is needed is a willingness to think out of the box.

    If a tree falls in the woods, but nobody is there to hear it, does it make a sound?Just because people are ignorant of something does not mean something is not there.

  2. Last time I checked, sodium azide was the "active" ingredient in car airbags. Synthesis is dangerous, and uses hard to obtain ingredients (sodium metal, hydrazoic acid). Shouldn't we be able to go down to the car junkyard, cut open a few airbags, and get ourselves a nice pile of sodium azide? Controlled thermal decomposition could yield quite a bit of powdered sodium, and some nitrogen gas. I think anyone reading this knows what they would do with a pile of powdered sodium blink.gifMy questions for you: How would I go about doing this "safely"? What tools would I need to get at the good stuff? How do I find a local car junkyard?

  3. I was thinking about galvanic corrosion recently, and I got an idea. If you can increase the reacting surface area of a piece of iron by many times, you should be able to make it corrode very quickly, maybe even enough to boil water. You could start out with copper foil, or a foil of any metal lower than iron on the reactivity series. Get some trash cans or other large containers. Some copper wire, rubber tubing, gravel, water, and optionally salt will be needed as well. Cut out a lot (I'm really not exactly sure) of sheets of copper foil that will fit into your container. Take one sheet, and place it flat on the bottom of the container. Take a small handful of clean gravel, and place it on the middle of the foil sheet, then try to spread it evenly across it. Do not use too much gravel! Take a small piece of copper wire, just longer than the gravel layer is thick, and attach it to the foil. No soldering. Tie it on, get creative. Put another layer of foil on top of the gravel. Attach the wire to the second sheet, so both sheets are connected. Do everything you did for the last layer. Keep it up until the can is full. Once you reach the top, add an extra long piece of wire to the exposed foil, maybe 2 or 3 meters. Fill the whole thing up with water. The salt will make corrosion much faster, so if you have that, add enough to make at least a 5% solution. The more the merrier, right? Get a small, .5-1 liter container, and fill it up with some of your saltwater. Keep it level in height with the top of the trash can, Very Important. Use the rubber tubing to connect the two containers. Make sure that the tube fills with water, this will allow ions to flow in the solution. Take any piece of iron, pure is better, but steel will work. Avoid galvanized and stainless. The smaller the piece is, the more concentrated the heat will be, don't use anything too big. Hook the iron up to the long wire, and stick it in the second container.Corrosion should begin almost immediately. Add some vinegar if you want. You could wire up multiple cells to make things faster. Here is an idea/diagramI know, it looks like it was drawn by a kindergartener. But I did it in paint, and I'm tired.Tell me what you think, if you try it tell me how it works for you.
