This started out as a short comment in a friend’s blog, but got out of control.
It is easy to get timescales mixed up, and associate the gradual movement of continents with the rise of sea levels.
Continental drift takes place over tens of millions of years. It is a very slow-moving process. the various […]
Mogur commented on a previous post to the effect that this year’s increase in Arctic ice is not necessarily a refutation of global warming.
I’d agree: One year of uptrend in ice, even a few as we’ve now seen, is not even particularly indicative, let alone conclusive. But I do see evidence that there is […]
This caught my eye. Computer chips have long been increasing in performance, but always seem to be on the edge of running out of how much further they could go. How small could the components be? How fast? How tightly can they be stacked? They’ve been pressed into ever-smaller surfaces at ever-higher densities.
But now […]
The “Conception post” was a follow-on to answering a series of questions posted at Citizen Tom’s blog. The questioner is a commenter who goes by the moniker “mastersamwise” — and he asked these questions:
A friend was complaining recently about an “absurdity” of multiple universes as portrayed on a recent PBS/Nova broadcast. Here’s a slightly edited version of my reply:
There are two general concepts of alternative universes; one is unknown and unknowable in our present understanding, the other is an absurdity that is considered by some to be […]
In the 1990s, less than one-tenth of 1% of funds went for programs aimed at high-achievers or gifted students. Most of the funds went for the “underserved.” I use that word a lot, professionally, and it refers to poor students (in both senses of the word), and especially to illegal immigrants. If you want to […]
Except from a conversation with a rather vehement and objectionable catastrophist, who was asserting a consensus with AGW (anthropogenic global warming). I replied:
Incidentally, I agree with AGW. Specifically, in answer to the questions posed on the famous survey, that it has warmed in recent decades and that humans have contributed some non-zero amount to […]
This is a rather nifty little short film about out-of-this-world technology:

The word “carbon” is often used as a shorthand for carbon dioxide. Environmentalists talk of “carbon footprints” and “carbon pollution” and have injected such terms into the language. But not too long ago, we all recognized that Earth’s biosphere was one of “carbon-based life.” That is, of course, still true. But humans are changing the […]
(Some visitors to Citizen Tom’s blog are True Believer Catastrophists on global warming, and some (not the same folks, generally) are Young Earth Creationists or variants thereof. Perhaps I am destined to make enemies wherever I go, but that is not my intent. To a creationist, I had commented:)
In the meantime, regarding creationism, I […]
