 Argonauts: Memes and Policies

These are the Argonauts’ core memes. Individual argonauts might be motivated by some or all of them. • Social Responsibility: Scientists must be held to professional standards, especially as technology becomes more enabling and potent. Profit or political/military gain should not be the deciding factor in which technologies are pursued; whatever benefits transhumanity most should prevail. • Opposing Government/Corporate Intervention in Science: Science should not be limited or restrai...

 The Origin of Life from Molecules

The account of the origin of life that I shall give is necessarily speculative; by definition, nobody was around to see what happened. There are a number of rival theories, but they all have certain features in common. The simplified account I shall give is probably not too far from the truth. We do not know what chemical raw materials were abundant on earth before the coming of life, but among the plausible possibilities are water, carbon dioxide, methane, and ammonia: all simple compounds ...

 Complexity of the Octopus

[The octopus has] an amazing skin, because there are up to 20 million of these chromatophore pigment cells and to control 20 million of anything is going to take a lot of processing power. ... These animals have extraordinarily large, complicated brains to make all this work. ... And what does this mean about the universe and other intelligent life? The building blocks are potentially there and complexity will arise. Evolution is the force that's pushing that. I would expect, personally, a lo...

 All is Connected in Quantum Physics

Quantum theory thus reveals a basic oneness of the universe. It shows that we cannot decompose the world into independently existing smallest units. As we penetrate into matter, nature does not show us any isolated “building blocks,” but rather appears as a complicated web of relations between the various parts of the whole. These relations always include the observer in an essential way. The human observer constitute the final link in the chain of observational processes, and the propert...

 Carl Sagan Summarizes Evolution of Life On Earth

Eventually, many billions of years ago, a molecule was formed that had a remarkable capability. It was able to produce, out of the molecular building blocks of the surrounding waters, a fairly accurate copy of itself. In such a molecular system there is a set of instructions, a molecular code, containing the sequence of building blocks from which the larger molecule is constructed. When, by accident, there is a change in the sequence, the copy is likewise changed. Such a molecular system – ...

 Big History as a Fable

Once upon a time, about ten or fifteen billion years ago, the universe was without form. There were no galaxies. There were no stars. There were no planets. And there was no life. Darkness was upon the face of the deep. The universe was hydrogen and helium. The explosion of the Big Bang had passed, and the fires of that titanic event – either the creation of the universe or the ashes of a previous incarnation of the universe – were rumbling feebly down the corridors of space. But the gas...
