Richard Dawkins, This Is My Vision Of "Life" ... if there is life elsewhere in the universe, it will be Darwinian life. I think there's only one way for this hyper complex phenomenon which we call "life" to arise from the laws of physics. ... it produces machines which can run, and walk, and fly, and dig, and swing through the trees, and think, and produce the whole of human technology, human art, human music. ... at some point in history, about 4 billion years ago, a replicating entity arose, ... the great majority of survival machines are actually discrete organisms, Edge /15-05-01

In a world first, Chinese scientists have reported editing the genomes of human embryos. ... to reignite an ethical debate. ... to modify the gene responsible for ß-thalassaemia, a potentially fatal blood disorder ... Some say that gene editing in embryos could have a bright future because it could eradicate devastating genetic diseases before a baby is born. Others say that such work crosses an ethical line ... rejected by Nature and Science, in part because of ethical objections /15-04-28

Neuroscience reveals the seemingly novel fact that “we are not the authors of our thoughts and actions in the way people generally suppose”. ... the brain’s chemistry consistently determines a decision prior to our consciously making that decision. ... This is a process not dissimilar to intuition, ... Our choices may be rooted in our physiology, our genetic makeup, but out of these arises something that was once called “character”, and it is this that is the final arbiter on choice. ... Character is the complex accumulation of our history ... the absence of the idea of a free will in antiquity. In its place is the notion of the good life /15-04-28

About 2,500 years ago something changed the way humans think. ... rise to the world's major moral religions ... morality as a necessary social stabilizer in increasingly large and volatile human communities. ... recent study published in Current Biology point to a different factor: rising affluence. ... religions abruptly emerged when members of a population could reliably source 20,000 calories of energy a day ... with a steady energy supply, we had more time to cooperate, cultivate skills and consider consequences. /15-04-20

Debunking of Moral Realism ... Sharon Street ... The argument begins from the empirical premise that evolutionary forces have influenced our moral beliefs, something that is plainly true, to a sceptical conclusion that our moral beliefs are unjustified. So the argument is essentially that since moral beliefs were not caused by moral facts, we have no reason to think that our moral beliefs could be true. ... What distinguishes the evolutionary debunker from other anti-realists is that she is not trying to show that there are no moral facts, but rather that there is no moral knowledge. ... natural selection are driven by fitness and survival, and truth doesn't enter the picture. ...

We need new models of popular physics communication ... that clearly explains the mysteries of quantum mechanics to the layman would not be especially enlightening. ... Very, very few people lie at the intersection of "highly accomplished scientist" and "highly accomplished writer", and Dyson fits the bill ... Laura Fermi's delightful "Atoms in the Family" ... physics as poetry, physics as drama, physics as fiction, physics as comic characters /15-04-13

Are We Really Conscious? OF the three most fundamental scientific questions about the human condition, two have been answered. First, what is our relationship to the rest of the universe? Copernicus answered that one. We’re not at the center. We’re a speck in a large place. Second, what is our relationship to the diversity of life? Darwin answered that one. Biologically speaking, we’re not a special act of creation. We’re a twig on the tree of evolution. Third, what is the relationship between our minds and the physical world? Here, we don’t have a settled answer. ... We have an awareness of information we process. What is this mysterious aspect of ourselves? ... a shift from a credulous and egocentric viewpoint to a skeptical and slightly disconcerting one: namely, that we don’t actually have inner feelings in the way most of us think we do. ... Patricia S. Churchland and Daniel C. Dennett. .. How does the brain go beyond processing information to become subjectively aware of information? The answer is: It doesn’t. ... And there is no way for the brain to determine through introspection that the story is wrong, because introspection always accesses the same incorrect information. ... Attention: a real, mechanistic phenomenon that can be programmed into a computer chip. Awareness: a cartoonish reconstruction of attention .. awareness is not an illusion. It’s a caricature. ... a system needs at least a rough model of the thing to be controlled. ... It’s best to be skeptical of intuition. (OCT. 10, 2014) /15-04-10

number theory, algebra and string theory ... in particular dimensions, the first two of which were 1 and 196,883 ... j-function ... The monster has more than 1053 elements ... the universe has tiny hidden dimensions, too small to measure, ... Umbral Moonshine Conjecture ... K3 surfaces ... when we understand what moonshine is, it will be in terms of physics ... The string theory underlying umbral moonshine is likely to be “not just any physical theory, but a particularly important one,” ... connection between moonshine and quantum gravity ... 194 classes of black holes ... Umbral Moonshine Conjecture is “like looking for an animal on Mars and seeing its footprint, so we know it’s there,” /15-04-10

whether time really passes? ... Parmenides believed the universe is the set of all moments at once. The entire history of the universe simply is. ... We have to be a little careful about what we mean by “time does not exist.” ... Time might instead emerge to play an important role in the macroscopic world of our experience, even if it is nowhere to be found in the final Theory of Everything. /Sean Carroll /15-04-07

„neo-Darwinian synthesis” .. grounded on chemistry, and thereby on physics … For biology. Like geology but unlike chemistry, there is another problem. Living things are what they are not only because of the principles of physics, but also because of a vast number of historical accidents … “emergence” .. But it does not apply to everything .. we must have reference to deeper, more truly fundamental, principles of physics. … We do not know how long science will continue on this reductive path. … Steven Weinberg To Explain the World /15-04-06
