  1. Um, no. Marijuana is a psychedelic actually. It has a stimulant effect on the circulatory system. Ironically, some people swear by its ability to treat their anxiety while others go into uncontrollable anxiety upon ingestion. I agree that marijuana does not treat seizures or their catalysts, but it can be mighty effective at reducing the number and severity of occurrences. For some people, especially in extreme cases, this can be an absolute godsend.
  2. I came up with an idea for a short story, but I don't know if someone has already written something similar. I'm hoping the more read around here can advise. I only have the very basic idea for plot so far. Companies are mining aluminum from landfills and it has become a global business worth billions. At one of the landfills, a mutated bacteria is exposed and it causes a massive outbreak. The story would conclude with scientists finding another microbe in the same landfill that has adapted genes necessary for resisting the bacteria. Some themes I would like to explore: human waste, the
  3. I was thinking about this the other day. In this age of alternative facts, it forces people to speak in absolutes. My thoughts on this matter started after I read a lively debate on Pluto being a planet, or not. Mountains are the same. It just depends on perception at this point, but we could easily set standards. As Turtle described, there are a lot of factors to consider. So rather than an easy answer, you would have to consult a taxonomic field guide to know for sure that what you are looking at is a defacto mountain (and not just a silly looking hill). I propose a few standards: 1. H
  4. Cool thought experiment. I thought by the title that you were going into photon torpedo territory, but really you are just working on the first hypothetical part which is "How does one store light?". Some answers from my point of view: 1. I don't understand the assumption. Do you mean that the inside of the box would get brighter because it is absorbing more photons? If so, I think that is valid. 2. The radiation pressure is not really significant with photons. Well, at least naturally occuring ones at distance. I don't think radiation pressure would be a factor in a photon torpedo. 3. The 9
  5. The constant speed of light is not artificial. It can be measured. In fact it was measured to a high degree of accuracy before SR. http://math.ucr.edu/home/baez/physics/Relativity/SpeedOfLight/measure_c.html
  6. I'll go ahead and guess 15 for #1. The first axis is passed at 7 pennies, as is the next. Since the spiral veers away, it looks like it will take twice as many. Since there are only six pennies since the last axis was traversed, I am going with a gut feeling of twice as many (+1). I would imagine this pattern would repeat along this path (basically a squared equation). But I could totally be wrong. lol
  7. It says the video is not available, even when I manually paste the end of the URL you provided. :(
  8. There are all kinds of rabbit holes to venture through here. My favorite is a link from the wiki sticky beads that Craig posted, Abraham-Lorentz force. https://en.wikipedia.org/wiki/Abraham%E2%80%93Lorentz_force "It was thought that the solution of the Abraham–Lorentz force problem predicts that signals from the future affect the present, thus challenging intuition of cause and effect." That is something I will have to try and wrap my brain around. It is only tangentially related to the topic of this thread, but interesting nonetheless. As far as gravity waves are concerned, we are stil
  9. Can you point me to Tesla's ideas on this? I will delve into the links you have provided. Thank you! I took pre-calc twice: once in high school AP and once in college. Should I skip ahead? I remember functions (y=f(x) and all that) but maybe it couldn't hurt to refresh. And...I just answered my own question. ;) Thanks again for the link!
  10. I had a dream about a month ago. I can't recall the exact details of the dream, but I was left with a pressing urgency. From what I can recall, I was speaking to Einstein. It became clear to both of us that something was missing. I also was left with the feeling that I was on the verge of discovering levitation. It was a crazy dream. It has left me with an unending quest to get to the bottom of it. Obviously, this is a Herculean task and I unfortunately don't possess the mathematical prowess or understanding of QED to get even close. Hence, I am posting here in hopes that I can either mak
  11. Great article from a theoretical physicist that started a consulting job for amateur physicists. https://aeon.co/ideas/what-i-learned-as-a-hired-consultant-for-autodidact-physicists
  12. Interesting reply, Craig. I seem to recall the Starwisp idea (perhaps from these forums many years ago as I have not read Forward's book - will have to check that out). 250 gs to Jupiter in about 8 hours seems crazy to me. How powerful are these microwaves?
  13. In this article, they talk about a tiny wafer-like sail that could be powered by an orbital laser. Unfortunately, they don't give any specifics or details. How would this work exactly? It also made me start thinking about the lasers. If you shoot a laser in space, does it travel backwards from the force? Photons don't have mass, but they have energy. Wouldn't Newton's third law apply here? Wouldn't this mean that an orbiting laser would have its orbit slowly decay without some compensation from thrusters or something? There are tons of other questions too...What about space debris? How do
  14. I agree with letting it go if there is no significant harm from the irrationality, but there is still a financial burden and they have talked my wife into getting the pearl powder so it's eating into our money (not anything major, but still). I'm actually not even sure if CaCO3 has any affect of skin. Perhaps it does, but my main point to these people was that you can purchase CaCO3 a lot cheaper than imported pearl powder from China. Chalk is also CaCO3 and it defintely feels soft when rubbed on the skin, but this is obviously more of a result of the powder being very fine (small grain size
  15. A few colleagues of mine have been purchasing Chinese "pearl powder". When I remarked that it is basically calcium carbonate, I got widespread disvowment. How can I convince these people that ground up pearl is the same as CaCO3?
  16. I came I saw I left I'm back!
  17. Actually, the wavelength of light stretches over distance due to dark energy. This is why we see a Doppler Effect in the universe. Of course, this is imperceptible to the human eye within the solar system. As for the intial question, I think Maddog outlined it pretty well. If you want *exact* colours for the human eye on the planet's surface, then you would have to go there yourself. But a close approximation can be had from using the data that probes have provided. It might be better to approach this subject one planet/moon at a time. The ground-observed sunlight on The Moon is going to
  18. Is it unreasonable to think that our sub-atomic make-up is not pruning us for the world? Sure, we have CERN and Dark Matter, but is that any more real than our connections to each other? If we admit that there are no 'metaphysical' connections between living beings, what then? I don't believe in magic, but I also don't believe in 'status quo'. If it is so easy to dismiss the notion of sub-atomic forces acting at distances (as has been experimentally proven), then what holds us together? A less than adept critic might say, "Our hearts! We beat as one!". An adept critic might sigh and either t
  19. Urain, unfortunately, terms like "denser existence" have no meaning in Science (at least how it is understood in English, by me). I *think* I understand what you are getting at, but it's hard to tell because it's written in a way that is confusing. Can you try to rephrase this without using terms like "denser existence"? As to the original question...I am going to vote "yes". It is silly to think otherwise...matter occupies space. At the very most basic level, space can be defined using a coordinate system for four dimensional spacetime. In a practical sense, this means that my body has h
  20. Anyone ever seen it? If not, you can watch the whole thing on Youtube at this link: http://youtu.be/VT50SV3W5K0 I would be very interested to hear people's impressions of this film. It was life-changing for me. It deals with topics that have been discussed here, mainly quantum mechanics and "spookiness at a distance". The big take away point for me was that our minds have potential that is largely left untapped. It's inspired me to delve into meditation and see if I can unlock some of that unused potential to create more fulfillment in life for myself and those around me. I have doubts ab
  21. It seems that you are making an argument for pig experimentation. Otherwise, you have to continue your first argument and make a case for human chip implants.
  22. Great thoughts...But think about this... We can look at space as merely the distance between macroscopic objects, but what about the substances therein? Even in the most disparate reaches of the universe, there exists electromagnetic energy. As we know, energy is equivalent to mass. Hence, the universe has a pervasive mass about it. We can always shrink the distances between particles until there is only "space". And then we have to define it...and that's what you're getting at, right? ;) The problem I have with defining space as a relative distance is that it is just that...a relative
  23. I agree and celebrate your ideas of freedom from slavish thoughts. Nonetheless, I think Hawking deserves a bit more respect for his ideas. It takes a stroke of genius to think about quantum separation. I agree that it is not perfect and leaves something to be desired. That doesn't mean the idea is invalid. Until there's a better explanation, it's the best we've got, no?
  24. No apologies needed...this stuff is heady...especially for us non-physics students... The time a black hole takes to evaporate can be determined by Tev. The critical factor is the event horizon diameter (or spheric volume). The equations can be found here: http://en.wikipedia....ole_evaporation If you need help with the math, please post back and someone can help you out. For most Super-massive Black Holes, like those found at the center of galaxies, the evaporation time is *very long*. That is to say that they will be around long after this Solar System is dead and gone. Indeed, they
