In the February 2007 issue of Wired James Gleick wrote:
"Is the universe actually made of information? Humans have talked about atoms since the time of the ancients, and ever-smaller fundamental particles of matter followed. But no one even conceived of bits until the middle of the 20th century. The bit is a fundamental particle, too, but of different stuff altogether: information. It is not just tiny, it is abstract - a flip-flop, a yes-or-no. Now that scientists are finally starting to understand information, they wonder whether it’s more fundamental than matter itself. Perhaps the bit is the irreducible kernel of existence; if so, we have entered the information age in more ways than one."
