Prime Slaughter: Playful Prime Numbers
Starting from the difficulty of creating playful representation of domain-specific abstract concepts, this study discusses the design of Prime Slaughter, a computer game aimed at facilitating individual sense-making of abstract mathematical concepts. Specifically the game proposes a transpositionmathematical concepts. Specifically the game proposes a transposition of primality and factorization...
متن کاملGaps between Prime Numbers
Let dn = Pn+i ~Pn denote the nth gap in the sequence of primes. We show that for every fixed integer A; and sufficiently large T the set of limit points of the sequence {(dn/logra, ■ • • ,dn+k-i/logn)} in the cube [0, T]k has Lebesgue measure > c(k)Tk, where c(k) is a positive constant depending only on k. This generalizes a result of Ricci and answers a question of Erdös, who had asked to prov...
متن کاملGenerating Prime Numbers
A number p is prime if it is a natural number greater than 1 whose only divisors are 1 and p. The first 25 prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97. They are quite randomly distributed among the natural numbers with no natural way of getting from one prime number to the next prime number. Each number must be tested for prim...
متن کاملPrime-perfect Numbers
We discuss a relative of the perfect numbers for which it is possible to prove that there are infinitely many examples. Call a natural number n prime-perfect if n and σ(n) share the same set of distinct prime divisors. For example, all even perfect numbers are prime-perfect. We show that the count Nσ(x) of prime-perfect numbers in [1, x] satisfies estimates of the form exp((log x) log log log )...
متن کامل9 About certain prime numbers
We give a necessary condition for the existence of solutions of the Diophantine equation p = x + ry, with p, q, r distinct odd prime natural numbers. MSC (2000): 11D41,11S15.
