  1. Yeah, those are total bullshit. Phosphoric acid (which is what Coke contains) converts iron oxide into iron phosphate. Effectively, the flaky rust changes into a stable coating (more compact than the rust - which is why it could free my valve). This phosphate coating then protects against further rust.
  2. It works very nicely in some circumstances. I had a wing fuel tank drain valve seize up once. Dumping it in a glass of Coke freed it up quite quickly. The acid may be fairly weak, but the effervescence helps to get it into places where a plain liquid would probably not go (so it has to be fresh Coke, not that flat stuff left over from last night!).
  3. The universe is defined as everything that exists.
  4. We have a uniform system based on one minute of earth's arc. It's called the Nautical Mile - ask any pilot or sailor.
  5. Pretty sure there are no Masons here. Nearest thing I ever came across in Tanzania was several years ago in the Mara when I encountered a bunch of drinkers calling themselves 'Masike Acoholics Club'.
  6. I read an article recently (can't find it now) which said that Freemasonry is dying out both in UK and USA due to the increasing age of existing members and a falling off in recruitment rates for younger members.
  7. I said: So I should use a different clock for the time I waste reading gibberish as opposed to the one I use when I'm getting something done? You appear to have completely missed the point.
  8. Congratulations - concise and sensible. Keep to this standard of reply and you will find your reputation rising rapidly. Re-reading this, It might sound rather patronizing - it's not intended to be

  10. Number of things to do tends towards infinity as time available approaches zero.
  11. Do the studying first - once you have learned physics you will know why things like this are impossible.
  12. Please go and look at Donald Simanek's website https://www.lhup.edu/~dsimanek/museum/unwork.htm. It will save you a lot of wasted time and disappointment.
  13. I work for a Community Based Organisation that is mainly concerned with setting up early learning schools (ECD), microfinance for women's groups in poor villages, advice and help for small farmers and advising and helping youth groups. My jobs include designing school buildings, writing and producing books (in Swahili) for young children and keeping the computer system up and running. I don't think any of it benefits the rich in any way whatsoever.
  14. The point is not that bees can see colour. It is that they can remember colours and make judgements based on those memories. To do that they must have an 'inner experience' of colour. No way can you put this down to reflex.

  16. From: http://currentaffairs.gktoday.in/bees-choose-flowers-landing-color-petals-07201414231.html As per a scientific study, Bumblebees select most nutritious flowers for providing best food for their young simply by looking at the colour of the petals even before landing on the flower. As bees do not ingest pollen unlike nectar while foraging on flowers, it has been unclear whether they are able to form associative relationships between what a flower looks like and the quality of its pollen. The study used bumblebee foragers housed under controlled conditions to test whether they do learn about flowers during pollen collection. The findings showed that bumblebees can individually evaluate pollen samples and differentiate between them during collection, quickly forming preferences for a particular type of pollen. They are able to detect differences in pollen, even before landing, which means they may be able to discriminate, just from the colour of the petals, which flowers are richer in nutritious content.
  17. Try actually doing something instead of sitting around whining. Here's some inspiration for you - three boys - all under 15 at the time and with minimal resources - who have become famous for their achievements. 1) Richard Turere http://www.engineering.com/DesignerEdge/DesignerEdgeArticles/ArticleID/7046/Kenyan-Teen-Invents-Lion-Repellent-Device.aspx 2)Erasto Batholomeo Mpemba https://en.wikipedia.org/wiki/Mpemba_effect 3) William Kakwamba http://williamkamkwamba.typepad.com/williamkamkwamba/page/7/ And this is just in my part of the world. How many others are there elsewhere? So get off your ass and do something.
  18. Did you actually read it. "The minerals which form carbonaceous chondrites are capable of synthesising carboxylic acids, amino acids and all the nitrogenous bases which form ribonucleic acid (ARN), considered to be the precursor of the first living organism." (note: ARN is what we know as RNA) "those minerals which reached the Earth's surface and were heated in the presence of both water and formamide would be able to reproduce the organic compounds fundamental to prebiotic chemistry."
  19. Spanish National Research Council (CSIC) The results of these experiments signal that these meteorites possess the amazing properties of catalysing complex organic compounds which are not present in terrestrial rocks. The minerals which form carbonaceous chondrites are capable of synthesising carboxylic acids, amino acids and all the nitrogenous bases which form ribonucleic acid (ARN), considered to be the precursor of the first living organism. "The data obtained indicates that, even if chondrites were pulverised and lost their organic compounds during the phases of deceleration and ablation in the atmosphere, those minerals which reached the Earth's surface and were heated in the presence of both water and formamide would be able to reproduce the organic compounds fundamental to prebiotic chemistry. This clearly points to life being fertilised from outside Earth's atmosphere- life which could reach any part of our Solar System and, for that matter, of the Universe wherever conditions were conducive to maintaining liquid water for a reasonable length of time. Mars, Europa and Titan could possibly be excellent candidates for our exploration" indicates Trigo.

  21. I find that the quickest way to kill a computer is to not use it for a couple of months. I've had three PCs die since December purely from having been left unused for a while.
  22. Nobody is ever going to care about you if all you can show to the world is hate. It is you that has to change. Then you will find that the world changes with you.
