When pondering how likely life is to develop on other worlds, or what types of life might develop, we always have to always bear in mind that we currently only have one example to work with. And that example has one extremely unusual attribute, a large moon, at least large in relation to the size … Continue reading Did a cosmic fluke make life on land possible?
“The Universe Should Not Have Lasted for More than a Second”: The limitations of scientific theories
Stan Hummel called my attention to, and asked for my thoughts on this article: Big Bang Theory Challenged --"The Universe Should Not Have Lasted for More than a Second". British cosmologists are puzzled: they predict that the universe should not have lasted for more than a second. This startling conclusion is the result of combining the … Continue reading “The Universe Should Not Have Lasted for More than a Second”: The limitations of scientific theories
Collapse: How Societies Choose To Fail Or Succeed, a brief review
After my post the other day on what fields I thought someone needed to be familiar with for coming up with credible theories about why civilizations collapse, a number of people recommended I read Jared Diamond's book, 'Collapse'. I finished it this week, and like the other books I've read by Diamond, I enjoyed it. … Continue reading Collapse: How Societies Choose To Fail Or Succeed, a brief review
Fluid tests and quantum reality
The other day, I mentioned that I had some sympathy for the deBroglie-Bohm interpretation of quantum mechanics, namely an interpretation that there isn't a wave-function collapse as envisioned by the standard Copenhagen interpretation, but a particle that always exists but is guided by a pilot-wave. It turns out that there are some people doing experiments with … Continue reading Fluid tests and quantum reality
How life transformed the planet – Robert Hazen – Aeon
In my post on how similar or dissimilar life might be if evolution started over, I observed that much of the environment that life operates within is itself generated by other life. It turns out that goes deeper than I imagined. I knew that things like oxygenated atmosphere and soil were products of life, but it turns … Continue reading How life transformed the planet – Robert Hazen – Aeon
The Paleo delusion, and a delusion about that delusion
Today at lunch I listened to the latest Point of Inquiry podcast, which was an interview of Marlene Zuk about her new book on common delusions about evolution and the paleolithic life style. These misconceptions usually run along the lines of assuming that since we evolved to be hunter gatherers, that we should live like those … Continue reading The Paleo delusion, and a delusion about that delusion
Sean Carroll defends philosophy
Sean Carroll, theoretical physicist, has a post up on his blog telling his fellow physicists to "stop saying silly things about philosophy". The last few years have seen a number of prominent scientists step up to microphones and belittle the value of philosophy. Stephen Hawking, Lawrence Krauss, and Neil deGrasse Tyson are well-known examples. To redress the balance a … Continue reading Sean Carroll defends philosophy
Captain Phillips
Last weekend, I finally saw the movie Captain Phillips. I had been a bit slow to watch this one, because I wasn't sure how the events would be portrayed. I was pleasantly surprised to find the movie to be a mostly thoughtful chronicle of those events, although I don't doubt that it took some dramatic liberties. … Continue reading Captain Phillips
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?
Ruth Chang: How to make hard choices
The TED talk by Ruth Chang gets at some of the points I've made before, namely that reason only carries you so far, and that reason exists to serve intuitive goals. This comes out in hard decisions, when reasoning by itself is often insufficient, and we have to fall back on our innate values, on … Continue reading Ruth Chang: How to make hard choices
