متن کاملEvolution of Information and Complexity in an Ever-Expanding Universe
Using the usual definitions of information and entropy in quantum gravity and statistical mechanics and the existing views about the relation between information and complexity, we examine the evolution of complexity in an ever expanding universe.
متن کاملThe Expanding Polymerase Universe
Escherichia coli DNA polymerase I (pol I), discovered by Arthur Kornberg and colleagues in 1956. Thirteen years later, Paula de Lucia and John Cairns, at Stony Brook, New York, isolated an E. coli mutant, polA (its designation being a play on de Lucia’s first name, as proposed to Cairns by Julian Gross) that seemed to have less than 1% of the normal pol I activity. From this strain, a new DNA-p...

متن کاملEntropy in an expanding universe.
The question of how the observed evolution of organized structures from initial chaos in the expanding universe can be reconciled with the laws of statistical mechanics is studied, with emphasis on effects of the expansion and gravity. Some major sources of entropy increase are listed. An expanding "causal" region is defined in which the entropy, though increasing, tends to fall further and fur...
