PROBABILITY DISTRIBUTION OF DISTANCES BETWEEN

I learnt about arXiv a couple of years ago, when my research advisor sent me a link to his paper. Today, many physisists publish their papers in arXiv prior to sending them to pee-reviewed journals. It helps them share their findings faster and more effectively. For instance, many scientists in developing countries have no means to read articles in Phys.Rev., so arXiv is e great help in their everyday work.
