Do you think we will ever run out of natural resources? If so, how soon do you think we'll run out?

Is there any way to "fix" the way we measure time? Right now we have a 60 unit format for seconds, minutes, a 24 unit for hours, a 28-29-30-31 format for days and a 364 1/4 for years with a 100 incremental . Anyway to make it all into a singular unit like Decimal or Hexa or Octa?

How would you explain wave-particle duality to a non physicist?

Making Ammonium Perchlorate from near scratch

15 posts and 0 image replies omitted. Click to view.
Alright, /sci/, this is my first post here. I don't really know etiquette yet or anything since I usually post on /k/. I don't have any college under my belt and regretfully didn't take high school chemistry either, so you can understand why I'm having a hard time wrapping my head around chemistry and rocket science. What I basically want to know is how to make Ammonium Perchlorate from scratch. Scratch being table salt, because from what I've read through the right processes you can get it eventually. I may have read the process a dozen times but it just makes my head hurt and nothing else, it just won't click. I blame my lack of chemistry foundation. Nevertheless, this interests me mainly because I want to make what boils down to a mini rocket project. I want to see how cheaply one can have this stuff made and how this budget rocket fuel performs with aluminum, mainly wanting to determine how much room it would need to accelerate and hold steady a small rocket. Thanks, sorry if I broke etiquette or something. I'd also request you keep any explanations in layman terms so I can understand even with my extremely basic to nonexistent background in chemistry and advanced math.

Hey /sci/, I'm taking earth & space grade 12 and my culminating assignment is making a report on black holes, only issue is that i have no idea what I should talk about when it comes to black holes. Any suggestions?

String Theory

String Theory 6 posts and 0 image replies omitted. Click to view.
Anyone in this field? I saw a video where Cosmologist/whatever Sean Carroll said "if you're into string theory you're been hanging out on the wrong street corners". It got a laugh, but lots of people do it. Is progress easier to make than in other areas of HET? Does it alienate you from peers in more conventional forms of modern physics? Does the AdS/CFT correspondence give you a huge boner?

How come all organisms on earth descend from a single organism? Shouldn't there be several evolution trees?

Yesterday an AI managed to pass the Turing test: source: http://www.telegraph.co.uk/technology/news/10884839/Computer-passes-Turing-Test-for-the-first-time-after-convincing-users-it-is-human.html From the article: Professor Kevin Warwick, from the University of Reading, said: ''In the field of artificial intelligence there is no more iconic and controversial milestone than the Turing Test. ''It is fitting that such an important landmark has been reached at the Royal Society in London, the home of British science and the scene of many great advances in human understanding over the centuries. This milestone will go down in history as one of the most exciting.'' Might this development spark a revolution in the field? Can I have my robot servant/mistress now? What does /sci/ think?

Air freight

Why don't we just conduct freight shipping with balloon air craft? Is it a viable/cost effective method?
