Questions for my readers

Over at Atheist Homeschooler, I posed the following questions to Fiery Ewok on the Open Forum 3 post. Since Complete Materialist is a new blog and I don't have an established readership, I'd like to get some idea of who's reading, what interests them, fires 'em up and makes them tick. Then, when my choice of blog topics is up in the air, I'll let my reader's interests tip the scales in favor of one to their liking.

Answer any or all. As you address these topics, feel free to toss in whatever creative spin you have on the question at hand.

• What's the latest book you've read?

• What's your favorite area of science?

• What's the most recent thing you can think of where evidence new to you has forced you to accept a new understanding of an idea or to simply discard an old understanding?

• What one fact about the natural world do you think would benefit humankind the most if it was known by every person on the planet?

• Can you prove?: for an arbitrary integer greater than zero, the sum of its digits is evenly divisible by 9, if and only if the integer itself is also evenly divisible by 9.
