Climate persistence and memory

Seed bank persistence and climate change

The strong mechanistic relationship between climatic factors and seed dormancy and germination suggests that forecast climatic changes will significantly affect seed bank persistence. This review focuses on the potential impact of changing temperature, rainfall and fire regimes on the longevity of long-term persistent seed-banks. Currently, there are few studies investigating the mechanistic re...

The Persistence of Memory

Many sequences from number theory, such as the primes, are defined by recursive procedures, often leading to complex local behavior, but also to graphical similarity on different scales — a property that can be analyzed by fractal dimension. This paper computes sample fractal dimensions from the graphs of some number-theoretic functions. It argues for the usefulness of empirical fractal dimensi...

of Amnesia,” writer Gore Vidal comments at one point in Why We Fight. This comment struck me more than anything else in the movie, especially considering numerous utter falsities stated by the Bush administration about which I had forgotten. “There is no doubt that Saddam Hussein now has weapons of mass destruction,” Dick Cheney said in 2002.

Persistence of Memory and the Comma Bacillus

“T anyone should condescend to die of cholera at the bidding of so insignifi cant a creature as the comma bacillus,” wrote Marcel Proust, should not be astonishing to those in the know. Plagued by illness from childhood, the author was very much in tune with medicine, which he pondered often in Remembrance of Things Past (1913), his monumental novel on the nature of memory. He also knew about c...
