When I shop for fruit & melons I like to hold a grape next to a cantaloupe & think of Earth next to Jupiter. Then I eat Earth.

A television advertisement must illustrate the scientific method to substantiate any claim.... That is why stains are lifted, ring-around-the-collar is removed, paper towels become soaked, excess stomach acid is absorbed, and headaches go away-all during the commercial.

Space only becomes ordinary when the frontier is no longer being breached.

I am convinced that the act of thinking logically cannot possibly be natural to the human mind. If it were, then mathematics would be everybody's easiest course at school and our species would not have taken several millennia to figure out the scientific method.

That the north star is the brightest in the night sky. I'd guess about 9 out of 10 people think this. But it does not require a grant from the National Science Foundation to learn the answer.
