1 1 Physical Limits Chip designers are running up against the laws of physics. Ten years from now, chips will run at 30 GHz and complete a trillion operations per second. Unfortunately, with today's design technologies, those chips would be putting out the same amount of heat, proportionally, as a nuclear power plant.
2 2 Physical Limits & CPUs We have hit the wall of physics in our CPU clock speeds Intel announced in 2004 that it would not attempt to make processors that run at speeds greater than 3.6 GHZ Future CPUs will have multiple Cores to increase performance and bandwidth
3 3 Future Computers Few argue that the next generation of computers will be nearly invisible, meaning that they will blend in with everyday objects. Flexible ink-like circuitry will be printed onto plastic or sprayed onto various other substrates, such as clothes.
4 4 Wearable Computers-Now
5 5 Wearable Computers- future?
6 6 Wearable Computers
7 7 Wearables

11 11 Edmund Gunter, ~1620 The Calculating Line (early sliderule) Lengths from origin proportional to the logarithms of the registered numbers Used in conjunction with a compass to multiply & divide Sliderules popular to ~1970 (example, circular sliderules)
12 12 Wilhelm Schickard, 1623 Calculating Clock First automatic calculator Used by Kepler to calculate astronomical tables Incorporates Napiers Bones Adds, subtracts, multiplies and divides six-digit numbers (with carry) Overflow indicated by ringing a bell
