  1. Mathematically, in a simple a logical sense, time just does not seem correct to me. Despite the fact that I observe it. But in order to move from one second to another, we have to travel half that distance in time. And half that distance. And half that distance. To infinity. So theoretically, we cannot move forward in time. We would have to travel through an infinity of infinities between an infinity of intervals of time. Xeno's arrow could never have never hit it's target then. It couldn't even leave the bow by this reasoning. So time seems to be just the stitching together of brief instances of existence of matter in a certain arrangement, translating the information from one instance to the next. Now of course this is all basically human reasoning, and we know how flawing that can be sometimes. If you didn't know better, you could likely go your entire life thinking the world could be flat and that the universe revolves around us. Fortunately, observation and science is ultimately fact and proof. Sorry if my explanation of my thoughts was not clear. But to those who could read through the glorified delirium, can anyone tell me about how it is that time (and thus movement) is possible? Or at least explain whatever theories or such there are?
  2. First. Dumping all the nuclear waste from the process of nuclear power into the ocean would not be a proper answer. Of course we care about the "things" that live in our oceans. The radiation would not only poison the life in the oceans, but through the food chain would continually poison all creatures that consume those creatures and all the creatures that consume those creatures and so on. Humans are ultimately at the top, and we would lose one of the largest food sources in the world. This is just an immediate effect. The half-life of the isotopes from the byproduct of nuclear energy varies, but the effects would persist for decades (I am not a nuclear engineer or physicist, but this is just basic high school chem, bio and physics).Not to mention dumping radioactive material in the ocean would not result in it sinking, but just some sort of radiation soup of the ocean that would spread via the Coreolis Effect and the ocean currents, reaching America, Australia, Oceania, Asia, Africa, and in smaller effects, Europe, likely. Levels of radiation have been detected on the west coast of the United States due to the Fukushima Daichi disaster. That was just a single, isolated event. To continuously dump the amount of nuclear waste from the proposed massive nuclear power system on the Polynesian and Micronesian islands would be terrible.To say that dumping the waste in the ocean seems that it would be analogous to saying that dumping pollutants into the atmosphere doesn't affect us because we're on land. It would do immense harm to the ecosystem and would cause a massive collapse of the environment, likely. Not to mention the difficulty of transporting energy across the oceans to any of the continents. It would require an extreme amount of resources if you plan to send energy through electricity, because of the degredation of current and resistivity of wires, etc. Power plants are best organized as they are, I would guess, because they are more concentrated to areas where there is a greater demand for energy and a ready and easy supply of the resources to power it. The Pacific Islands have none of these things. As for the reason for opposition to nuclear power, it could be driven by political and economic support for the all-mighty coal and gas power companies, but it also because of a more-likely-than-not "bad rap" for nuclear, with Chernobyl, Three Mile Island and Fukushima Daichi. Public awareness of the possibilities of safe and extremely efficient energy would be helpful in their support. The original two disasters, on a basic level, were caused by a lack of knowledge on the technology, and all three because of insufficient safety regulations. If the regulations were more strictly enforced, then it might be a different story. I have not heard of the previously mentioned reference to cancer incidents around nuclear power plants, but a similar public health violation can be thought of in coal and gas power plants, along with hydraulic fracturing. All of these problems could be fixed by tight regulation on emissions by the government in the respective areas such that it is both clean and profitable. Hopefully. EDIT: Typo

    AC/DC Components

    While I am not quite old enough to recall such pre electric ignition, the concepts hit home. Thanks for the help

    AC/DC Components

    Ah interesting. But if I were to use a bridge to convert AC to DC, then wouldn't I then need to reconvert it as the DC current flowed to an AC power source? I wouldn't think you cab have AC flow out and DC flow in. Or did I get tripped up somewhere?

    AC/DC Components

    I understand the principles of AC and DC current. Fine. But somehow until now I never thought of the reasoning behind components specifically for either. What is the difference? Is it just that in AC components that current has to be able yo travel in both directions, and DC components current can only travel through one direction? Then in essence, wouldn't a DC switch, for example, be the same as an AC switch with two diodes facing the same direction in both input and output? I am probably mistaken in my reasoning but a little education here would help.
  6. I do have a breadboard, though I am not sure of the specs on it. Well, time to start plugging and playing!
  7. With some recently acquired components from an old television my Physics teacher wasn't using anymore (he pulled out the old cathode ray tubes, my friends got speakers, I got circuit boards), I decided to utilize the capacitors to make a bank in order to form a single stage coilgun, before moving onto a multi-stage coilgun with the same components. Here is a basic schematic, which I put together earlier, though I feel as though I am missing something here. Afraid of making what we call "the magic smoke" instead of a functioning circuit of components, I decided to play this one safe. I am probably going overkill with four capacitors with such high capacitance, and I will probably limit it to 1 or 2 (though I have 5 that I am aware of, will probably go to a future multi-stage coilgun). Self-explanatory list of components: L1: Charging indicator light S1: Charging activator, specs unknown S2: Firing Activator Switch, specs unknown C1-4: Capacitor bank, 9v,2200uF COIL: 5cm coil, ~100 wrappings. Thoughts, comments, concerns?
