Any luck on convincing that guy CLJ?

OK, try these: History of speed of light another evidence Special Relativity this last one contains a detailed mathematical explanation of that guy seems to need! These are quiet detailed links so I hope you manage to go through them! Cheers And I'd advise you to read this one too: Has speed of light changed?

God changed the speed of light??? This guy is not even a creationist or a materialist! Because creationists strongly support the idea that fundamental laws have not changed. And on the other hand he's not even a materialist because they don't believe that there is a God!

I think it should be the other way around! Ask him where to direct you so you can see for yourself what does he mean by saying "the speed of light has changed". Speed Limit And you're not supposed to convince him (or anyone) with all costs about anything. Just tell him scientific experiments that deny him and if he doesn't want to accept that, well it's his problem. Ignorance is growing these days:rolleyes: ! Light speed has changed! What a thought man!!! :doh:

It seems to light to me! I mean, if it runs over something even quiet small, I think it will lose balance, and it's also quiet hard to maintain balance in three wheels. Then it also seems dangerous if you suffer accidents, you'll probably get "tossed", like agenchange said, because there seems to be no place in front of you, not enough room. Then what happens if there's a storm going on, and there are strong winds, I really think that it's light. And if the road is slippy, the back wheel will cause problems to keep the balance. The wheels seem not to be connected so strong with the body of the car. I mean look at this man: If it hits a corner the wheel will probably "cut off" and then the cost of attaching it again I guess will not be that low! I don't really know! The ones who designed that are probably experts and they must know better than me, but it seems dangerous to me. I wouldn't get one! Oh, and yeah, it's also ugly!

Hi everyone! I just wanted to say to everyone "happy holidays" (including Bajram, Christmas, New Year, etc) and I hope that this incoming year will be better than the one we are just leaving behind. Let this year be the year of peace, tolerance, science and the year of success in everything. Happy Holidays everyone:-) ! Shade

Thanks for all this Martin, if really helped. Universe expands, this is something that now everyone knows, and what's interesting is that that expansion is accelerating (dark energy), but yet there is something that holds the universe together known as dark matter. But there seems to be not enough dark matter (23%) to pull the universe together, compared to dark energy (73%). But will universe go on expanding forever? Will everything keep moving away from everything? One thing that makes me doubt about this is the fact that acceleration can't just go one increasing all the time. I understand that universe is infinite, and that everything fits in infinity, but hey, if this acceleration keeps on increasing all the time, at some point it will reach the speed of light, and what will happen then? Nothing can go faster than the light, or can it? And there's also dark matter, and maybe out there is more dark matter that we imagine and which at some point may pull this universe back together. Or is it that the universe will keep on expanding until this acceleration reaches the speed of light, and then all will come back together. That makes you think, you know!

Don't worry man, it's no big deal, just be a little more formal, nothing more! I'm not sure if this is what you're asking, but take a look at this: http://sriconsulting.com/SRIC/Public/NewsEventsArt/ACSBohlmann.pdf

You mean finite matter in infinite universe? If you mean that, then finite fits in infinity, actually everything fits in infinity! But first you're saying "universe that goes on for ever" than you're mentioning "edges of universe"! If universe goes on forever, then it must be infinite, because nothing can go on forever without being infinite! And if it is infinite, then I think it has no edges! I'm just assuming!

Please be more polite and if possible type the complete words

Actually it wasn't me I think who used that figure, I was just quoting someone (I think). And about that 20%, I'm using the words of my professor when saying that. I guess I have to ask him again for a more detailed explanation, and then I'll get back to you. Thnx iNow

yes, absolutely well said! This is otherwise called active transport because it requires energy. As it is moving the ions from e place with less concentration to a place with higher concentration, this is not a physical process so it needs energy. And active transport uses about 20% of our energy.: And the speed of nerve impulses is somewhere around [math]120\frac{m}{s}[/math], but pain signals seem to travel only two feet per second, this is why you first feel the pressure, then pain!

If I were you, I'd go to university! Economical problems are a big barrier to overtake (I've been through them too), but if you take university seriously after you start, you'll probably be noticed and get a scholarship, and then just keep on studying, of course if you're willing to do that. And if you have good marks, then someone will definitely will be interested to have you in his/her company, and so you'd get a job anyway. I'd strongly recommend to go to university!

If you mean from a faucet like this: Then I think the distance would remain the same, I mean the gravitational attraction would be the same for all the drops, so there is no reason they could get closer or further":doh:

OK swansont, I'm sorry, I didn't know about this. And thanks for info...

Water is made up of molecules too, is it? And what happens when molecules hit each other? [hide]They generate heat, right! So the temperature increases. While stirring the water, you are increasing the kinetic energy of the molecules, and with the increase in kinetic energy, the probability that molecules will hit each other increases too. And as the hits of molecules are grater when you stir water, then hits generate energy, and that causes the increase in temperature.[/hide]

yes, it does.. it's reactions with water are: Mg + H20 ----> MgO + H2 ----(cold water) Mg + 2H2O ----> Mg(OH)2 + H2 ----(hot water)

Well, I doubt that practically there can be any sort of that fission (then it'd be micro-fission) small enough only for shooting a bullet. And you mentioned water, in nuclear reactors water is used as a moderator (to slow down neutrons) because it does not absorb neutrons, so it makes possible nuclear reactions. So I can't really figure out how does that sniper work!!!

Laminar flow: [math]\frac{\Delta v}{\Delta t}=0[/math] ; [math]\frac{\Delta p}{\Delta t}=0[/math] ; [math]\frac{\Delta \rho}{\Delta t}=0[/math] Reynolds Number: [math]Re=\frac{dv\rho}{\eta}[/math]

OK thanks, but I thought of using liberty basic because it seemed very easily to be picked up (I've already made dome prototypes). But I guess I'll stick to Python again!

:D thanks for the warm welcome mooeypoo, but can I program EXECUTABLE programs with Liberty basic?

A friend of mine gave a program called LibertyBasic, and it seems very practical and easy to be handled! I was wondering if i can make runnable programs out of it, not just script ones??

here's the rule: [math]loga^k=k\times loga[/math]

Listen HallsOfIvy. there are different ways of solving logarithmic inequations, and what I did above what just applying one rule [math]log\frac{x}{y}=logx - logy[/math] to that equation! if the solution [math] x \in (-\infty , -2) [/math] doesn't work for [math]log(x-1) - log(x+2)>0[/math] then just switch the equation to [math]log\frac{x-1}{x+2}[/math]
