  1. Now apply that same thinking to your own beliefs.
  2. Gut feeling tells me it will be, either way. Disregarding the ancient philosophers, Islam scientists were indeed the first to make use of an experimental scientific method. So one has to wonder why, to reiterate, the Quran states fresh and salt water don't mix. After all, using the scientific method, it takes around at most a minute to disprove. Maybe a few minutes more to see if the two separates.
  3. Fairy tales can be real to-believers-at least. You cannot disprove the tiger John Cuthber mentioned, never. It does not mean that that lack of evidence is the evidence of abscence of the tiger. Special pleading, a logical fallacy. http://en.wikipedia.org/wiki/Special_pleading There are no evidence of a rain god. Since it rains, belief in such an entity would be called a rational belief. Then why don't you believe in such? Unless you want to also claim that there is evidence of Santa because some kids get presents in the winter, then no. Because you can't prove a negative. If you're using Russell's argument with the tea pot, why did you arrive at a different conclusion than him? Could it be because you don't understand philosophy? Another user on this forum (krash661) uses the following question a lot, in various forms: What's the difference between a god that doesn't exist and a god that can't be detected? If we can't detect your god empirically, then why conclude that it exists? Can you name any written works naming Jesus that were written during his lifetime? So belief is a cultural construct which emerge from our culture, and is not passed to us from some deity?
  4. I'd agree with Moontanman in that you don't know what science is. The scientific method isn't about following the person with the best theories, it's about the theories themselves. You claim Islam suggested evolution (I never get to see your link, so only reading what you claim here), but so what? Is everything Islam says infallible because they seems to have gotten one thing right? How about the claim in the Quran that salt water and fresh water doesn't mix? Shall we believe in that on the merit of your evolutionary claim? If not, then why are you mentioning Islam like it's some method of clairvoyance? http://old.richarddawkins.net/discussions/551812-fresh-water-salt-water-doesn-t-mix-according-to-qur-an-prof-dawkins-in-real-time-with-bill-maher http://councilofexmuslims.com/index.php?topic=4537.0 http://www.infidels.org/library/modern/denis_giron/islamsci.html
  5. Nicely done. Was it all down to the bad transistor?
  6. Let's not involve conspiracy theorist fantasies, shall we?
  7. If you vote the Earth is flat, the Earth would remain round.
  8. From the site: What, it won't have a warp engine?
  9. I wouldn't say useless. After all, your idea led to you asking a question, which in the end hopefully led you to a better understanding (assuming I explained it properly and correctly) of the theory behind what made you ask the question in the first place. As for looking down the path of a ray of light; a ray of light isn't an actual, solid ray, but consists of photons. Once a photon reaches a receiver (such as your eye), it was by necessity sent out in the past.
  10. Sure. Let's say you write a message on a tennis ball. You then start a timer when you throw the ball towards a wall. After 1 second, the ball will hit the wall. It will then return to you 1 second later, and you can read the message you sent to yourself from the past. Looking at a mirror 2 light years away is pretty much the same. After a photon (light) is emitted from Earth, it's not affected by anything happening here. So a bunch of photons will still "show" what went on here at the time they were sent out. So when you flash a light towards the big mirror 2 light years away, the photons will travel for 2 years, hit the mirror, be reflected, then come back here 2 additional years later. It will not show what happens 20 years in the future, because those photons have not been emitted yet. Now, time dilation when it comes to space travel and the like is something different. It does not, however, mean you can work around cause and effect. http://en.wikipedia.org/wiki/Time_dilation http://en.wikipedia.org/wiki/Retrocausality
  11. My point exactly (I think). Whatever battery or charge left in the box won't be enough to turn on all 4 simultaneously.
  12. 2 years ago, some photons were emitted towards the mirror placed 2 light years away. In 2 years, we would see the photons coming back to us, after bouncing off the mirror. This would mean we would be able to see 4 years into the past, because that's when the photons were sent off from Earth.
  13. ...what? To elaborate, I don't think saying "X is wrong" immediately followed by "I don't know what X is" lends credibility.
  14. Why doesn't he turn on all of the lamps simultaneously in the end?
  15. Ok, so you need to disconnect both the coil and the resistor to get that voltage? Or is it enough to just disconnect the coil? Sounds a bit like the coil might be the problem then.
  16. You seem to have a very poor understanding of how electricity is supposed to work. I suggest you remedy this before trying to get anything else peer reviewed.
  17. Ah, no. The link didn't link to the correct section. I fixed it now, but here's the first part of section 3.1:
  18. Not quite. It's actually the females that do the hunting in lion packs. Let's say the males have manes for social reasons. Read this section of the Wikipedia article on lions, and see if you can pick up the reason from it. Otherwise, ask away. Lion mane Edit: fixed link
  19. That's basically it! Both tigers and lions have adapted their furs to blend in to whatever habitat they've evolved for. Then it's down to the actual process of how it worked, but I'm sure you'll work that bit out. Here's a small list with other differences that may or may not be noteworthy in the context: http://www.diffen.com/difference/Lion_vs_Tiger Are you sure about the teeth? I haven't investigated it, but they look pretty similar to me: http://www.skullsite.co.uk/Tiger/tiger_lat.jpg http://upload.wikimedia.org/wikipedia/commons/9/91/Skull_lion.png Any apparent difference is probably minor enough to not worry too much about. Did you think about why males would have manes?
  20. The manes are a different matter, most likely to do with the way lions live in packs, as opposed to tigers. Most lions live in Africa, so not really a cold place. In a pack with one male and several females (and it's only the males that have manes), can you think of any reason a big furball for a head would be beneficial? Would it help if I suggested you look at similarities between lions and peacocks? As for the vegetation, think about it from the prey's point of view. It's easier to avoid carnivores if you can see them, right? Now, how would a tiger's stripes help in areas with vegetation (not necessarily trees), and how would a lion's golden color help on a sandy savanna?
  21. You'll have to show what you've come up with so far, and people will attempt to guide you in the right direction. Nobody will do your full homework for you. That said, tigers usually prefer habitats with more vegetation than lions. How would the different habitats favor the characteristics of either species?
  22. It's kind of hard to know what's wrong without actually having a look at your setup. The obvious thing to do would be to check if you've made a mistake. Is everything rotated the way it's supposed to? Is everything connected where it's supposed to be? After that, start measuring. Make sure pins 4 and 8 are supplied with the right voltage (should be 12 V if you're connecting it to a car battery). Make sure pin 3 is around 1.7 V below what you measured at pin 8 (if I'm reading the link below right). Make sure your components can operate at 12 V, so they don't burn. I'll look into the resistors you changed for 27k, see if they'd make a difference. http://en.wikipedia.org/wiki/555_timer_IC#Astable
  23. I'm sorry, but I'm crying with laughter right now!
