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).

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