  1. When a magnet is placed directly over a super conductor it will display properties of levitation. If the magnet is removed, the super conducting material will still display these properties. This is known as the flux trapping effect.

     

    My question is how do you reset the super conductor to its original state. Is it as simple as raising the temperate above the material's critical temperature?

     

    Also is there any way to avoid the flux trapping altogether and have a material that is purely diamagnetic?

  2. We All Know That Most Mammals Produce Their Own Vitamin C. My Question Is, What Would Happen If There Was A Proto-virus Created That Reenabled The Almost Fully Intact Pseudo-gene Present In The Human/primate Genome For Vitamin C Synthesis? Sorry About The Format Of My Post.

  3. Possibly because the habitable zone of B is further away from the instability zone giving it a better chance of containing a planet within the habitable zone.

     

     

    I think both A and B should top the list because of the close proximity of the system to our own. If we actually find a habitable planet around either one it wouldn't be an impossibility to send probes and eventually go there.

  4. This is akin to asking what is the "frame rate" of the universe. If time moves along as frames in the linear 4th dimension we could possibly determine its speed.

     

    Lets do a thought experiment. Imagine a single hydrogen atom floating in space. Now look at its electron zooming around the nucleus at the speed of light. This electron is moving incredibly fast but is limited in speed by c.

     

    Now lets view this from a different perspective. Imagine viewing this atom with its electron spinning at the speed of light from the perspective of time. That is, break the event up into frames and spread it along a time line. If we can figure out how many frames are in one second we would know the speed of time.

     

    Again lets take a look at this electron. In one second it will have traveled an incredible distance of 299,792,458 meters around its nucleus. And in 1 meter of travel .00000000333 seconds will have elapsed. Now lets look at plank's length. Supposedly this represents the smallest distance something can move from one position to another. If our electron moves one plank would this not represent one "frame"?

     

    So all we need to do now is figure how many plank lengths an object moving at the speed of light will traverse in one second.

     

    Plank length is about 1 x 10^(-34) meters

    Speed of light is about 3 x 10^8 m/sec

     

    (10^34 plank lengths in a meter) x (3 x 10^8)

     

    ~ 3.0 × 10^42

     

    In one second an object at the speed of light will move 3.0 x 10^42 plank lengths. So we can say the universal frame rate(or speed of time) is 3.0 x 10^42 frames per second.

     

    Someone correct me if im way off.

  5. Nutmeg is worthless, I wouldnt attempt a psychoactive dose.

     

    If your going to do it anyway I would read over this first.

    http://www.erowid.org/plants/nutmeg/

     

    Also from Wikipedia.

     

    In low doses, nutmeg produces no noticeable effect on the mind or body. Large doses of 7.5 g or more are dangerous, potentially producing convulsions, palpitations, nausea, eventual dehydration, and generalized body pain. In amounts of 10 g or more it is a mild to medium hallucinogen, producing visual distortions and a mild euphoria similar to that derived from Marijuana. However, use of nutmeg as a recreational drug is unpopular, due to the potential painful physical side effects, the risk of Nutmeg Psychosis (see below) and the inconveniently long span for which the effects of a single dose can persist. A user will not experience a peak until approximately twelve hours after ingestion, and effects can linger for up to an additional twenty-four hours afterwards. Any unpleasant side-effects would persist throughout this thirty-six hour period.

     

    A risk of any large-quantity ingestion of Nutmeg is the sudden onset of Nutmeg Psychosis, an acute psychiatric disorder marked by hallucinations, excitement, thought disorder, a sense of impending death and agitation. Some cases have resulted in hospitalization and reportedly few who have experienced the effects of nutmeg poisoning recommend it or repeat the experience.

     

    Even in smaller doses, Nutmeg can be a toxic substance. Ingestion of as little as 5 g may cause dry mouth, fast pulse, fever and flushing. It has amphetamine-like effects and may lead to the ingestion of large volumes of water. There is no specific antidote; the adverse effects wear off after 24 hours (or more) of rest.

     

    Nutmeg is extremely toxic when injected intravenously. Nutmeg can also cause liver damage if used regularly in large quantities. Nutmeg has in the past been used as an abortifacient. Nutmeg can also cause death if used in large quantities, but this not a problem while cooking, since small amounts are used.

  6. This is known as the transit method but its not the only method used to detect and gather information about extra solar planets.

     

    According to wikipedia there are 7 total methods. Pulsar timing, astrometry, radial velocity, gravitational microlensing, transit method, the study of circumsteller disks, and direct observation. From what I know the most common method as of today is using radial velocity to detect the wobble of a star as the planet revolves around it.

     

    If a planetary system does not exist in a similar plane as our own the transit method becomes useless.

  7. Is it possible by using magnetic field blocking materials to build a motor that runs only on permanent magnets?

     

    Say you have metal shaft supported by two bearings on each end. In the middle of this shaft is a permanent magnet with the north side facing out and the south side facing inward toward the shaft.

     

    Right across from the magnet on the shaft is another larger permanent magnet that is encased in a magnetic shielding material. Part of this shield can open like a valve to let the large magnetic repulse the magnet on the shaft and then close as the magnet passes around again.

     

    Here is an animation to better describe what I just typed.

  8. Yeah, Callipygous has it pretty much covered.

     

    I'll add that the under the green heatsink is the northbridge chip. It controls the memory and AGP bus.

     

    And the small brown slot is an audio/modem riser slot. Its part of the PCI bus and is usually used for cheap software based modems. I don't recommend using it because it will kill your PC's performance.

  9. The two main actives in Tylenol PM are acetaminophen(tylenol) and diphenhydramine(weak anti-cholinergic/histamine).

     

    Dosages of 2500mg+ acetaminophan can damage your liver, especially if combined with alcohol.

     

    Dosages reaching 250mg of diphenhydramine will make you delerious and hallucinate.

     

     

    You should be fine if you only took 6. I've known idiots who take around 10 to get "high" and they survived.

  10. You can get compressed nitrogen cheap from paintball shops.

     

    Get an oxygen sensor and wire it up so that it activates a solenoid on the N2 tank when oxygen levels are too high and when the levels are too low have it activate a fan venting atmosphere into the tent.

     

    Maybe invest in an additional sensor and have it activate an alarm if the amount of oxygen in the tent drops to dangerous levels.

  11. Does there exist a limit to which a cargo carrying aircraft can be scaled up in size?

     

    For example:

     

    The Cessna 421 has a wingspan of 12m, a length of 10m, and a maximum take-off weight of 3103kg. This a common private plane.

     

    The Mcdonnell Douglass DC-9 has a wingspan of 28m, a length of 40m, and a maximum take-off weight of 55,000kg. This is a standard US military transport aircraft.

     

    The Antonov 225 has a wingspan of 89m, a length of 84m, and a maximum take-off weight of 600,000 kg. Only one exists. It was built by the soviets for thier space program that collapsed with the end of the cold war.

     

     

    Anyone can see the scale moving up largely between these similarly engineered aircraft.

     

    My question... is there anything keeping us from going larger? If we built an airstrip the size of a large city, how far would the laws of physics allow us to keep scaling up the size of our aircraft? Is it feesable with today's technology to build an aircraft say twice the size of the Antonov 225?

     

    Could we someday be living on flying cities gracefully skimming through the stratosphere? :D
