Mars is just dumb mass at the bottom of a gravity well; there isn't even a biosphere there. They should be working on uploading and solving the nanoassembly conformational problem instead. Then we could turn all the available dumb matter into computronium and use it for processing our thoughts. Long-term, it's the…
Game of Thrones takes place in a land that feels somewhat post-apocalyptic — there are occasional glimmers of hints that something really bad might have happened to Westeros long ago, and that's the reason for the irregular and attenuated seasons. But even more than that, we know Westeros is on the brink of a zombie…
...complex systems, such as financial markets or the Earth’s biosphere, do not seem to obey causality. For every event that occurs, there are a multitude of possible causes, and the extent to which each contributes to the event is not clear, not even after the fact! One might say that there is a web of causation. For…
Do you know the PDF of your shampoo? A PDF refers to a “partially diminished fraction” of an ecosystem, and if your shampoo contains palm oil cultivated on clear-cut jungle in Borneo, say, that value will be high. How about your shampoo’s DALY? This measure comes from public health: “disability-adjusted life years,”…
Evolution in the biosphere is therefore a necessarily irreversible process defining a direction in time; a direction which is the same as that enjoined by the law of increasing entropy, that is to say, the second law of thermodynamics. This is far more than a mere comparison: the second law is founded upon…
Even today a good many distinguished minds seem unable to accept or even to understand that from a source of noise natural selection could quite unaided have drawn all the music of the biosphere. Indeed natural selection operates upon the products of chance and knows no other nourishment; but it operates in a domain…
When some portion of the biosphere is rather unpopular with the human race–a crocodile, a dandelion, a stony valley, a snowstorm, an odd-shaped flint–there are three sorts of human being who are particularly likely still to see point in it and befriend it. They are poets, scientists and children. Inside each of us, I…
A lot of people ask, 'Do you think humans are parasites?' It's an interesting idea and one worth thinking about. People casually refer to humanity as a virus spreading across the earth. In fact, we do look like some strange kind of bio-film spreading across the landscape. A good metaphor? If the biosphere is our host…
