  1. Keeping in mind that the multiverse is still an idea with no concrete proof, I would like to ask some simple questions about it. If multiverse is real. Does that mean that there is an infinite amount of universes with infinite possibilities? Like a universe where our fantasy becomes a reality, for example?
  2. Wanted to ask a question. Am I correct in assuming that there is a part in the brain that is responsible for the way we see our body and other people and feel about our sexuality? The way it seems to me is that certain conditions can affect this part, changing its wiring and thus the way we see these things.
  3. Apologies, im a foreigner (english isnt my native language). And when the question popped into my head i didnt think it through all the way. So the question is addressed to those who are actually religious, and rephrasing should sound like this....I hope: why is faith relevant to you? what relevance does it hold to this moment, right now, at which you are living your life in? I guess the reason why i found these questions so interesting is because i cant answer them as well, simply because it has no relevance to me and im curious to know what would be the answer of a person that finds it relevant. Im guessing i made more then one grammar mistake in that previous sentence. XD
  4. These questions popped into my head, and i would like to see a different view on it. why is faith relevant? what relevance does it hold to this moment, right now, at which you are living your life in?
  5. I wanted to ask if there is an equation out there that describes what is real and what is not. Sort of like a ''mathematical backbone'' that can separate reality from an illusion. Is there such a thing in physics or is it just an individuals point of view?
  6. Thank you for clearing out what is HHO. About the part that I quoted, are you saying that there is a good chance of it being complete BS?
  7. How can I get HHO gas? Im guessing it has something to do with a special type of electrolysis.
  8. Hello! I am absolutely fascinated with physics, and the new topic is ''jet engines''. I would like to understand them more, maybe even build a basic one, but don't know where to start. Any recommendations for literature or websites that could teach me about these things?
  9. Greetings! I have these cool looking volcanic minerals that contained quartz (SiO2). And I was wondering... Is It possible to ''dissolve'' SiO2 with a type of acid or something similar?
  10. Greetings! I have sucesfully created a coilgun with 4 capacitors. Could someone tell me how to add extra phases? I know that each secondary phase will requier a different activation then the primary. Prohaps if i use optical sensors like this?(http://www.ebay.com/sch/i.html?_from=R40&_trksid=p2050601.m570.l1313.TR0.TRC0.H0.Xoptical+sensors.TRS0&_nkw=optical+sensors&_sacat=0) Also could someone tell me how to mount phases togeather?
  11. Very well, perhaps you could assist with my question? Can I use a 9v batery?
  12. Thank you for your cooperation. Now im at final stages of building the device. And i have a question. Can i use 9v batery to charge the capacitors? Because i've seen on some vids and pictures of devices with even multiple 9v bateries.
  13. Thank you for your answer. This is all werry helpful,however i have one more question about caps. 1)I will build a coilgun with capacitors simply because there is no time left. However could you tell me if I will be able to use capacitors with 5 pins? and If yes how will i be able to tell wich one is positive wich one is negative? 2)Is it possible for thease caps to explode? (P.S. Im talking about caps which were shown in previous link)
  14. Thank you for your reply. Now I have a question about capacitors. Im thinking about buying elektrolytic capacitors as shown here (http://www.ebay.com/itm/Aluminium-Elektrolytic-Capacitors-Screw-Terminal-Snap-In-Multi-Pin-/311154114632?pt=AU_Electronics_Wholesale_Electronics&var=&hash=item48723b0048) There are other electrolytical capacitors out there as well,however i chose thease,because of their high capacity at nearly similar voltage,the shipping is free and Germany is closer then China. However I am a bit confused now. 1) Is it possible to use a 5-pin capacitor for a coilgun? 2) I've red that electrolytical capacitors can explode.Can thease as well? And if they can what do i use so they don't? 3)Are thease type of capacitors ''mountable'' to a disposable camera circuit? Im planing to buy 470/470 uf,385v 5pin(only available) 85*C capacitors (4-5 capacitors in total) The original capacitor wich was attached to the camera was a 330v 120uf cap.
  15. Greetings! So Im making a coilgun for my science project at school,ofcourse my physics teacher thinks im insane. I would like to build a 4 stage coilgun with 20 capacitors in total. We were already sucesfull in assembling a single stage coilgun that used a ''ready'' circuit board from a disposable camera that already had a 330v 120uf capacitor attached to It. For the final version im planing to use 20x capacitors wich are either the same or with the same voltage and higher capacity. my questions are: 1)How do i mount the stages togeather? Because I couldnt find any ''real'' explination anywhere on the web. I know that it requiers a sensor of some sort or calculation. 2)Could someone recomend a website besides ebay where i could get a light barrier or a similar sensor unit that would be nice for for a coilgun online? Im asking for online because im preaty sure noone is selling what i need atleast in 200km radius.
