Who invented chocolate chips? The Guide contains math/science brain teasers, facts, stories about math/science, and computer code.

# The Description Below Is Better Than The Video Above

For every 50 dollars received, I will write up another 1-3 pages of the book and post it or link it below.  This is a sign of good faith.  The entire book, once finished, will have many more pages than just 2-3 pages per 50 dollars.

I TRULY ENJOY MATH, SCIENCE, ENGINEERING, INVENTING, POETRY, FOOD, and MUSIC . . .

There is possibly not enough space in the non-margin of my book for the last three in that list so we'll stick with STEM (Science, Technology, Engineering, and Math).  The Guide will be a collection of STEM stories, puzzles, experiments, and other odds and ends.  A few examples of stories to be fleshed out are:

Story 1: Edison finding the right filament for the common light bulb. (He tried many many metals and finally decided on Tungsten).

Story 2: How chocolate chips were "invented." (The quick run-down: a mother was out of pure chocolate so she decided to put broken candy bar pieces into cookies.)

Story 3: Zeno's Paradox wonders if ANYONE can beat the turtle in certain racing conditions. (The Main Question: If you have infinitely many positive fractions, can they all add up to something less than 100?)

Math and Science Stumpers and Experiments:

1) You have a glass of water with one floating ice cube sitting at the top.  When the ice melts, is the level of the water higher, lower, or the same as the height of the water before (assuming no evaporation, etc.).

2) What is (quickly) 52% of 25?  (10% of 20 is 20% of 10 . . . that's right you can pick which number has the percentage.  In the example 52% of 25 = 25% of 52 or one fourth times 52 or 52 divided by 4 or 13.)

3) Air is kinda cool (because it is not solid).  Place a candle on a table 1.5 feet away (or just a piece of paper slightly bent and standing up).  Place a round 2-liter soda bottle directly between you and the candle.  Hold your head at the horizontal level of the candle while being 2-3 inches away from the bottle.  If you blow at the bottle in the direction of the candle, the air will wrap around the bottle on both sides and put the candle out!

4) How many numbers from 1 to 1000 are perfect squares AND perfect cubes?

These stories, puzzles and much, much more are going to be in Brian's Guide.
