Friday's Fact

What will bounce higher a ball of rubber or glass? (equal size and dropped from same height)

Last week’s fact: You can sum the integers from 1 to 100 instantly by spotting that the sum is 50 pairs of numbers each pair summing to 101. The average being 50.5. By taking the average and multiplying it by 100 (50 pairs) you will get 5050.

1 + 100 = 101
2 + 99 = 101
3 + 98 = 101
100 + 1 = 101
Etc. The Avg. is 50.5

What amazes me is that Carl Friedrich Gauss solved this problem at age 7.
