1. Modelling evolution

Well, rather than a magical click my rationale was something along the lines of a mutation causing a new "trait" if that trait is helpful then the trait will propagate if it is harmful then the mutated genome would perish. As for your suggestion, I like that idea a lot so I'll implement it too. However when you say "insert random strings", its a bit ambiguous as to what you mean... Mathematically, what would the difference be between random point mutations and randomized strings. (Bear in mind a "non word" is treated as a non word until it is a valid word in its entirety)
2. Modelling evolution

When I was typing out my reply above I accidentally deleted the whole thing, when I retyped it I missed something crucial, typical! When defining terms, I meant specifically within this context. I wasn't sure exactly what Sharon was referring to by "string and word". Anyhow, in this particular instance I'm not terribly concerned with in depth biological simulation. More to provide a relate-able allegory, I am concerned however, that my lack of knowledge would lead to me making some assumptions that would mean I wasn't actually representing evolution. My aim is to show something rec
3. Modelling evolution

I'm not 100% clear on what you are saying, perhaps it would help to define some terms. Genome: String of character (initially random) Fragment: Sub-Strings of the genome bookended with whitespace. Word: Fragment that is also a valid english word. Thanks. Here is some output in case it helps make things a little clearer. A population of 10 genomes of length 50. Starting test environment...

4. Modelling evolution

Hi folks, I wasn't sure quite where to put this as it spans computer science and biology, but I'll leave it here for now. I'm hoping to be doing some work with STEM this summer, I'm a computer scientist so my focus will be mainly around that but this project is a good way of weaving several things together I think. I was watching a short film on evolution the other day and to cut a long story short I thought it would be nice to write some software that people could interact with and see evolution (or rather its principles) in action. This should provide an engaging overlap bet
5. Perpetual Motion!

Hmm, in that case, lets say i have a permanent magnet. I use the magnet to pick up a nail. With the nail attached is the magnet less magnetic? Edit: Also, lets say I do the same thing on the moon, gravity is less so the magnet does not have to do so much work, yet the mass of the nail remains the same. So would the magnet become less magnetic in proportion the the nail's weight or mass?
6. Perpetual Motion!

My point was that the super conducting electro magnets to not require a constant current to maintain a magnetic field. They are hugely powerful and could generate a MASSIVE amount of force pulling in a solid lump of iron. If the magnet was a permanent magnet then the metal block is now stuck unless you spend an equal amount of force pulling it back away from the magnet. However with a super conducting magnet and wires if you were to bleed off the current to another coil (or a "holding" circuit) you could pull the block back to its starting position and do it over again. No energy i
7. Perpetual Motion!

In what proportion to the amount of potential energy gained by the block?
8. How many choices you can make in 1 second

I think i see what you are getting at. Check out Planck time, then you might get a (slightly) more meaningful answer http://en.wikipedia.org/wiki/Planck_time Essentially, if we assume that any partial fraction of a planck time is meaningless (or impossible) then you have the maximum numbber of decisions you could make within one second. Roughly 1043 possible decisions. However, how did you decide on 50,000 options? A decision could be binary, just a yes or no. But what you calculated was the number of different permutations for your given situation, which is not the ma
9. Perpetual Motion!

I realise that just moving iron around doesnt produce useful energy in its self, but once you have something moving requiring no input energy, you can hook it up to a reciprocating arm or some such. The method of extracting energy from the system is not what i was concerned with. From my understanding, once the super conducting coil has reached superconducting temerature, very little further cooling is required they are well insulated. What you mentioned about the eddy currents is something like i was expecting. Lets say our lump of iron is a 10KG block moved vertically 1m. Is
10. Perpetual Motion!

With most perpetual motion ideas its immediately obvious why it won't work (beyond the fact that it would violate the laws of thermo dynamics). Energy lost to friction for example. . I know that I'm missing something here, but I don't know what. I was reading about mri machines and was intrigued to see that they use super conducting magnets and once the coil is magnatised a super conducting bridge is dropped down and the coil remains magnatised by the perpetually circulating current. Now, imagine two such magnets with the current being shifted between the two coils, via super cond
11. Problem with my ozone generator

Hmm just a guess, but bear in mind that glass becomes conductive at higher temperatures so a small hot spot would quickly become a bigger one and result in the problem you are seeing. Check for any stray mesh or anything that might be causing a hot spot to start.
12. Does anyone here use a seedbox?

Oops, it didnt occur to me to clarify! I was referring to a bittorrent seedbox, not the planty type, sorry
13. Does anyone here use a seedbox?

As above, anyone using a seedbox?
14. Platinum Catalyst Hand Warmer questions

From what i can tell, the "burning" of the fuel should only produce water and carbon dioxide, assuming that the fuel is relatively pure, because i could only find hand warmers that burned naphtha or LPG, both are mixed hydrocarbons. So with that in mind lets try and attack it logically. Please bear in mind that im not a chemist So, if we have 2 waste products: water and CO2, how do they make the pad degrade? It could be that the substrate (the thing that the platinum is impregnated in) is hygroscopic, and absorbs the water from the reaction. This is my best guess purely because i
15. Platinum Catalyst Hand Warmer questions

Hmm, that's interesting. The a catalyst is not "consumed" in a reaction so it shouldn't wear out. I suspect that the by products of the reaction are collecting in the pad and coating the platinum so it can no longer act as a catalyst. You would have to ask a chemist about what exactly is formed in the process, but i would suggest giving it a clean! Try water first, if that fails maybe an alcohol or some acetone might be worth trying. Good luck.
