In particular, the number of images a person captures in a lifetime is set to rise exponentially. The thousand (3) a year I take of my children on a digital camera are all precious to me. (4) a generation’ s time, my children’ s children will have total image documentation of their entire lives—a (5) log of tremendous personal value.
By then we’ll be wrestling with another question: how we control all the electronic (6) connected to the internet: trillions of PCs, laptops, cell phones and other gadgets.

Scientists say they have achieved small-scale nuclear fusion in a tabletop experiment, using tried and true techniques that are expected to generate far less controversy than past such claims.
This latest experiment relied on a tiny crystal to generate a strong electric field. While the energy created was too small to harness cheap fusion power, the technique could have potential uses in medicine, spacecraft propulsion, the oil drilling industry and homeland security, said Seth Putterman, a physicist at the University of California at Los Angeles.
Putterman and his colleagues at UCLA, Brian Naranjo and Jim Gimzewski, report their results in Thursday’s issue of the journal Nature.
41. Held up to ridicule
Previous claims of tabletop fusion have been met with skepticism and even derision by physicists.
42. Sound theoretical basis
Fusion experts said the UCLA experiment will face far less skepticism because it confor
