Coupled with the fact that conventional equations can describe only the simplest natural phenomena (you can write an equation for the orbit of a single planet around the sun, for example, but not for an entire solar system, let alone a living cell), the success of his simple programs made Wolfram suspect that science has been heading in the wrong direction for the past 300 years or so. Instead of trying to write complicated equations for everything, he says, scientists should have been searching instead for the cellular automata that correspond to what they are observing...
...this world. This photo of a stellar nursery is a close-up of the Cone Nebula, a cloud of gas and dust some 2,500 light-years from Earth. From top to bottom, the celestial pillar shown here spans 2.5 light-years--3,000 times the size of our solar system. Stars are being born within the cloud as dense knots of gas collapse and flare with nuclear fusion. Five billion years ago, when our sun was still a newborn, it was probably shrouded in a cloud like this...
...glass enclosure of the Greenhouse Cafe will receive a dual-glaze energy efficient coating, as well as increased solar shading so that the area does...
Last March, U.S. astronauts made five of the most challenging spacewalks ever attempted in order to give the venerable Hubble Space Telescope a new lease on life. The new digital camera and solar generators they installed boosted Hubble's optical power tenfold, essentially making it a new telescope with unprecedented reach and clarity...
Optimally, much more of the energy consumed in the U.S. would come from renewable resources. However, much of the necessary technology, such as efficient fuel cells, is still under development. The costs of a rapid conversion to solar or hydrogen production would likely cause an energy price shock that would seriously dampen the economy. But the present American system of electricity production is archaic. While 10 percent comes from renewable resources—mostly hydroelectric—and 20 percent is nuclear, 70 percent is from burning fossil fuels...
