The other day, I was reading a post by Ethan Siegel on his excellent blog, Starts With a Bang, about whether it makes sense to consider the universe to be a giant brain. (The short answer is no, but read his post for the details.) Something he mentioned in the post caught my attention. But … Continue reading 97% of the observable universe is forever unreachable

First Peoples and Neanderthals
This weekend, I finished off the last of the 'First Peoples' PBS miniseries on prehistoric humans. If you've watched other documentaries on human prehistory and found them interesting, then you'll want to watch this one to get the latest findings. It was fascinating. (A lot of people have mentioned 'Becoming Human' to me, which I've … Continue reading First Peoples and Neanderthals
‘The Selfish Gene’: Classic science worth checking out
I don't usually read old science books. After a decade or so, I find that their content tends to have too much dated material. But 'The Selfish Gene' keeps coming up in conversations, not just because its author, Richard Dawkins, is the world's most famous atheist, but also because of its core message, that genes are … Continue reading ‘The Selfish Gene’: Classic science worth checking out
The evolution of the scientific method.
Empiricism, the idea that sensory experience is a source of knowledge, is ancient. People have obviously learned through sensory experience as long as there have been people. Studying the night skies gave ancient humans insight into the flow of the seasons, crucial knowledge as the agricultural revolution kicked into gear. And farming techniques, medicinal practices, food … Continue reading The evolution of the scientific method.
There is only one dogma of science: truth is better than fantasy
Dave Pruett has a post up at the Huffington Post looking at a declaration of eight "eminent" scientists and scholars calling for science to move past its materialistic focus. The list of authors in this declaration includes Rupert Sheldrake, whose TED talk was removed from the TED site last year after an outcry from the scientific community … Continue reading There is only one dogma of science: truth is better than fantasy
Free will persists even if your brain made you do it
The free will debate has been going on for millenia and, like most philosophical debates, shows little chance of being settled anytime soon. A significant part of the debate is definitional: what do we mean when we say "free will." We can argue endlessly about what the term should mean, but it turns out that what most … Continue reading Free will persists even if your brain made you do it
Is logic and mathematics part of science?
Last week was scientism week at Scientia Salon, and I reblogged a post by Coel Hellier on a defense of scientism, mostly by arguing that mathematics was actually part of science. As I indicated in my comment on that reblog, while I agree with Coel that both logic and mathematics have foundations that are empirically … Continue reading Is logic and mathematics part of science?
The double slit experiment and the utter strangeness of quantum mechanics
Occasionally I remark about how illogical quantum mechanics is. Sometimes people either insist that it is logical, or simply assert some simple explanation that shows they don't really get how utterly strange this stuff is. This video of Jim Al-Khalili gives a relatively brief explanation of this experiment, including its freaky results. http://www.youtube.com/watch?v=A9tKncAdlHQ If Al-Khalili doesn't strike … Continue reading The double slit experiment and the utter strangeness of quantum mechanics
Science is about both ideas and data gathering.
Stan asked for my thoughts on this article: Science is becoming a cult of hi-tech instruments – Philip Ball – Aeon. The tools of science are so specialised that we accept them as a kind of occult machinery for producing knowledge. We figure that they must know how it all works. Likewise, histories of science focus on ideas rather than … Continue reading Science is about both ideas and data gathering.
If evolution started over, how similar would its results be?
Zach Zorich has an interesting piece at Nautilus asking if the world began again, would life as we know it exist? In less than five milliseconds, a Hydromantes salamander can launch its tongue—including the muscles, cartilage, and part of its skeleton—out of its mouth to snag a hapless insect mid-flight. Among amphibians, it is the quick draw … Continue reading If evolution started over, how similar would its results be?
