Hey RANDOM.ORG,

For the last three years, my internet friends do a March Madness Bracket competition. Whoever correctly guesses the most amount of wins.

Being a Canadian, I know little about US College Sports, and Basketball just isn't my sport.

I said I was gonna pass and they said. ‘No one gets a bracket right, give it a try, you could guess.’

Then I though how Random! So, every year I use a combination of random questions about universities I have never even heard about (which university is closer to the continental US, Which University has a bigger endowment, which university has a bigger student population)

For universities I have heard of, I used the Random.org coin flipper to flip 29 coins and then the majority of heads or tails wins. I also look away and click the flip again for a random number of times.

My success has been very limited to say the least! But I do have fun and I enjoyed reading your history of Random.org.

I do have to count the heads or tails manually to make sure one has won. But if you wanted you could add a total of heads or tails.

Anyways thanks for being so random I couldn't make a March Madness bracket without you!

I write and use molecular dynamics and Monte Carlo simulators which have their own pseudo-random number generators (for portability and reproducibility). These require the user to input a random number seed. If I want to perform an ensemble of N statistically independent runs (e.g., with different initial conditions), I need N independent seeds. So I use your site to generate seeds to paste into my input script, i.e., your random generator generates random seeds for input to a pseudo-random generator. Say that 5 times fast.
