3. As Geordie Rose points out, you can’t have a conversation with your laptop. “It’s worth stopping and thinking about why that is,” says the founder and chief technology officer of D-Wave Systems Inc., which sells what it says is the first commercial quantum computer. Part of the reason is that conversation is nonlinear, so such a feat would require fairly sophisticated artificial intelligence (AI).

5. It did not all use to be base 10! • Bottom up to follow the way plants grew • Numbers were often given names in terms of 20 for example 380 which equals 19 X 20 was literally names 19 – twenties in Mayan • 400 BC • Why was it base twenty?

6. Babylonian base 60 counting system • developed in 2000 BC • Still has influence on the number of degrees in a circle and time • Why 60?

7. MATH MAGIC • Pick a three digit number with all the digits being different (abc = 100a + 10 b + c) • Reverse the digits (cba = 100c + 10b + a) • Subtract which will yield 99a – 99 c=99(a-c) thus the only possible answers are 099, 198, 297, 396, 495, 594, 693, 792, 891) note middle term is always 9 and the first and last term always add to 9 this number is xyz • Reverse the digits again to produce zyx and add (100x + 10y + z) + (100z + 10y + x) = 101x + 101z + 20y = 101(x+z)+20y but y is always 0 and x+z is always 9 thus you get 101(9) + 20(9) = 1089 • TRICK • 1. pick any three digit number with different digits • Reverse the digits and subtract (bigger from smaller) • Reverse the digits of this new number and add • The result is always 1089 thus have them look at p. 108 and word 9.
