...Brass tacks: Apple took a computer, chopped off the keyboard and squashed it flat. It's reasonably powerful for its size. Nobody has independently benchmarked the new house-made 1-gigahertz A4 processor that powers it, but it never once stuttered in the demos, so let's just say it's somewhere between an iPhone and a netbook - toward the netbook end - and more than sufficient unto the day. The iPad is thin: half an inch (1.25 cm) at its thickest. It's light: 1.5 lb. (680 g), half of what a MacBook Air weighs. It runs a scaled...

...Eight Gigahertz. The M.I.T. team also had to design a new radar transmitter that would operate at eight gigahertz (pronounced with hard gs), which is 8 billion cycles per second. Radar beams of lower frequency would be significantly slowed down by electrons in the solar corona, making it difficult to separate out the delay actually caused by the sun's gravity. Corrections for Mercury's surface irregularity had to be calculated; round-trip time to a Mercurial valley would be longer than to a mountaintop. It was also essential for the researchers to screen out any extraneous radio...
