Xkcd perpetual motion

The comic is a satire of the way that conversations tend to go between physicists and perpetual motion enthusiasts (or cranks in general). Perpetual motion is the idea that it could be possible for a mechanical system to work indefinitely without any external input of energy xkcd.com is best viewed with Netscape Navigator 4.0 or below on a Pentium 3±1 emulated in Javascript on an Apple IIGS at a screen resolution of 1024x1.

  1. A perpetual motion machine is a hypothetical device that is supposed to move infinitely with no external forces helping it, thus providing an unlimited source of energy. The existence of such an object would contradict the laws of thermodynamics, so perpetual motion machines are known to be impossible
  2. If you could, you could make a perpetual motion machine. The Sun is about 5,000°C, so our rule says you can't focus sunlight with lenses and mirrors to get something any hotter than 5,000°C. The Moon's sunlit surface is a little over 100°C, so you can't focus moonlight to make something hotter than about 100°C

  5. Reporting could be seen as reporting to God in which he beleives. And that's the simple one. But also reporting that bug could be a report to the consciousness existing beyond the constraints of very comic Cueball is part of. That consciousness is then xkcd audience. Existence of such a consciousness beyond comic's universe would be the equivalent of God in some other universe. Self-reflective awareness of that alien existence, and not having a proof for its own comic universe, would make.
  6. Explanation. The comic is, in short, a new take on the common comedy trope in which characters in a thought bubble will sometimes look out of the bubble and talk directly to the person thinking it, another person nearby, or even the viewer. In this comic, however, it features Cueball and Beret Guy in a conversation together, in which Beret Guy.

The misguided search for a perpetual motion machine has run substantially longer than any attempted perpetual motion machine. |< <? > > XKCD has this right, both as an Internet phenomenon and regarding the alarming degree of scientific ignorance out there in the public. An example relevant to thermodynamics: About a decade ago, I was given the task of dealing with an enterprising young man who had designed and built a device that he thought would in fact be a perpetual motion machine Der zweite Hauptsatz der Thermodynamik besagt, dass man das nicht kann. Wenn Sie könnten, könnten Sie eine Perpetual-Motion-Maschine bauen. (Weitere Behauptungen, die ich hier weglassen werde) Ich glaube weder der Behauptung noch folge ich einer der Überlegungen. Erstens verstehe ich die Sache mit der Perpetual Motion Machine nicht Step one: Perpetual motion Step two: ??? Step three: Profit! Enjoy your pondering. Like Lik The non-existence of perpetual motion machines is a central tenet of physics, whatever people on the internet say. CQT researchers have found that you need the quantum world's uncertainty to uphold this principle. Comic by xkcd.com. Why should nature have this fuzziness? The new work gives us some kind of answer. Stephanie and Esther show that if we could break the quantum uncertainty principle, we could also break thermodynamics' second law. If quantum physics weren't uncertain.

Physics for Entertainment was written by Yakov Perelman in the 1920's (in Russian) and updated periodically through the 1930's. There are actually two parts to it, but Volume 1 is long out-of-print (though findable online — more on that later) First, let's get a few things out of the way: In real life, we can't put a metal pole between the Earth and the Moon.[1]For one, someone at NASA would probably yell at us. The end of the pole near the Moon would be pulled toward the Moon by the Moon's gravity, and the rest of it would be pulled back. nothing which was what the inventors of the perpetual motion machines sought to achieve. It is supplied from an outside source in our particular case, the surrounding atmosphere where it is stored up by sunlight. To all practical intents a gift-power machine would give the same advantage as could be derived from a perpetual motion

Update: I'm finally home after a month or so of nonstop events, including several xkcd book fund-raisers/signings.

I hope you like it. They're shipping out nicely, and we're about ready to order a second printing First, I don't get the thing about the perpetual motion machine: If this is regarding the first law of thermodynamics (conservation of energy), then it's perfectly possible to lose energy while still heating up an object, which would avoid perpetual motion, so I don't get the argument Alt-text: The misguided search for a perpetual motion machine has run substantially longer than any attempted perpetual motion machine.

Perpetual Motion in itself would be a nice curiosity if it were even achievable lol!! Problem gets even worse though. In order to get a perpetual machine to do work, you need (more energy out than put in) in other words it needs to make more power than it uses to keep itself running. Something has to propel the car or whatever load one places. Perpetual Motion. A perpetual motion machine is a machine that uses its own motion to fuel its own motion, and also performs work (i.e. applying force to move mass a distance, any distance) as a byproduct of this motion performed by the machine that perpetually performs the motion performed by the machine. Infinite Battle from EyesMaze. Renewable energy sounds so much more natural and believable than a perpetual-motion machine, but there's one big problem: Unless you're planning to live without electricity and motorized transportation, you need more than just wind, water, sunlight, and plants for energy. You need raw materials, real estate, and other things that will run out one day. You need stuff that has to be mined.
