Note #2 From the Book "Zero: The Biography of a Dangerous Idea"

The topic of zero came up at the first Read Group meeting at SCC on 1 February 2007. That meeting prompted me to dust off my copy of "Zero: The Biography of a Dangerous Idea." I had put the book on the shelf almost a year ago after reading the first 87 pages and I have found it necessary to re-read the first 87 pages.

We forget so that we can engage in lifelong learning.

The pentagram (five-pointed star) and the golden ratio (most beautiful number phi = 1.61803399). [page 27]

"Pythagoras was remembered for a different invention: the musical scale." [top of page 29]

Divide a line in two such that the ratio of the small part to the larger part is the same as the ratio of large part to the whole. [page 32]

"What shape, after all, could zero be?" [page 34]

I appreciated the Zeno Paradoxes while revisiting the first 87 pages. Zeno's paradoxes wouldn't have been so paradoxical if he had zero and infinity to work with. I had skipped the Zeno's paradoxes on the first read, but this time they were of increased interest because I had just read about them while reading the book "What the Bleep Do We Know!?"

New century starts in "00" or "01?" Image a child born in year 4 BC. Turns 1 in 3 BC, turns 2 in 2 BC, turns 3 in 1 BC and 0 in 1 AD, 1 in 2 AD and so on.

Kids are zero years old from time of birth until their first birthday, but parents rarely say their kids are zero in age.

Appendix B (proving 0 = 1) on page 219 ends with "Used unwisely, zero has the power to destroy logic."
