Hello. I'm currently making (or attempting to make...) a mathematical model based around mutation in a hypothetical organism (that is, one in which all the mutation rates and genome sizes are known).

I am currently graphing a particular feature of this model, involving mutation rates, but I don't have a 3x108 sided dice to change probabilities into certainties. In order to graph the number of mutations I need to know for certain if a mutation HAS or HASN'T occurred, not its chances of actually happening. Is there any free application which will "throw the dice" for me??

Thanks

So... you want a random number generator? If you're writing a program in C or Matlab or whatever, they should have a built in random number generator, or a library you can download by googling random number generator. What kind of random number generator do you want? 3x10^8 outcomes with equal probability?

This model is equations and spreadsheets only, and I no little about programming. Anyway, I need a genuine random number generator, not an periodic psuedorandom code-based number generator (One I was using seemed to repeatedly give me numbers over ^6, never below).

I found one genuine random number generator, Random.org, which is handy, but it can't handle numbers over ^8, which is unfortunate as I need one that can handle ^9 :(.

I just need a program that will randomly generate one number between 1 and 3,000,000,000.

I doubt whether being pseudorandom causes this. Did you check thousands of values for the few which would be less than 1000000?

I don't see why a pseudo-random number generator would be a problem. I've never heard of anyone having to use a genuine random number generator. If your pseudo RNG isn't giving you what you expect, you might be using it wrong or using one with a range of values not suitable for your purposes.

[strike]As for the RNG you were using, you can choose to get integers between 0 and ~10^8, so you could always just multiply every result you get by 10. This increases the mean and standard deviation, but if the numbers are close to uniformly distributed it doesn't matter.[/strike] Scratch that, that only works for real numbers. For integers you'd lose 1 to 9.

Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
Fermat's Last Theorem has long been one of the most famous mathematical problems, and is now one of the most famous theorems. It simply states that the equation $$ a^n+b^n=c^n $$ has no solutions with positive integers if ##n>2.## It was named after Pierre de Fermat (1607-1665). The problem itself stems from the book Arithmetica by Diophantus of Alexandria. It gained popularity because Fermat noted in his copy "Cubum autem in duos cubos, aut quadratoquadratum in duos quadratoquadratos, et...
Thread 'Imaginary Pythagorus'
I posted this in the Lame Math thread, but it's got me thinking. Is there any validity to this? Or is it really just a mathematical trick? Naively, I see that i2 + plus 12 does equal zero2. But does this have a meaning? I know one can treat the imaginary number line as just another axis like the reals, but does that mean this does represent a triangle in the complex plane with a hypotenuse of length zero? Ibix offered a rendering of the diagram using what I assume is matrix* notation...
