Eric Scerri has written the definitive history of Mendele’ev’s periodic table and how it came to be formulated. He also has a paper in which he proposes a new formulation, based on historical considerations of what it was that Mendele’ev was trying to do, and on more theoretical considerations of atomic number, not weight. Sciencebase discusses it here.
And of course, no post on the periodic table is complete without a link to Tom Lehrer’s “Elements” song. Here’s a fantastic version from YouTube:
My parents’ generation went through the second world war, fighting tyrants and ideologies that sought to control our everyday lives; for which reason they are sometimes called “the best generation”. Their parents’ generation fought world war one and went through the Depression. The generation I am the tail end of, the Baby Boomers, fought in Korea, Vietnam and the Cold War. Despite all this threat and challenge, liberty increased – by the early 1970s, there was an assumption that one had the right to behave in any way that didn’t harm another person, and that the law would eventually catch up. The right to free speech in countries that didn’t have it was increasingly taken, not asked for, and in countries that did, it was applied in ways that broke the comfortable conventions of the past.
What happened? In the past 30 years we have watched rights disappear under fear – fear of communism, fear of “moral decay”, fear of drugs, and now fear of terrorism. Our ersatz wars against these fearsome things has slowly eroded our rights – we are surveilled everywhere we go, we are prohibited from certain kinds of speech, and we are now inhibited in our movement across borders. In effect, as the old Soviet republics have become more open, the open world has become more Soviet. “Think of the children” justifies any restriction that makes the effects of these fears look trivial by comparison.
It’s about time we manned up. If our forebears can cope with risk and danger, and still be free, why can’t we? One in a hundred million are harmed by terrorist attacks, and we do exactly what the terrorists would like, and retreat from the modernism of free society and religious and political and economic choice across the board. Now we have democratic societies with warrantless wiretaps, indefinite detention without charge or legal redress, and my own country is about to implement censorship of the internet, without any oversight by judicial or public scrutiny! And both major parties accept this!
This is why I haven’t yet acted on my desire to have Linnaeus’ definition of Homo tattooed on my chest (that, and you’d never see the thing under all that fur)…
The UK government has banned the purchase of a dowsing device that is supposed to “detect” bombs in Afghanistan. Even the Afghans know this doesn’t work. [H/T Russell McPhee]
My disclaimer/policy on comments here has occasioned a bit of discussion on the tubes. Isis reckons that those who say it is a bad thing to piss on the rug will do it anyway when things get heated. Golden Thoughts compares this to the Civil Rights movement, and that those who say “don’t piss on the rug” are comparable to the people who arrested Rosa Parks for sitting on a bus. I have to say that I can’t see it, myself. But it raises an interesting issue: when is it right to be nasty in debate?
Because, sometimes, it is, and everyone agrees that it is. What we are arguing about now are the circumstances. More below the fold.
I have updated my paper on deflating genetic information. The new version is here. Details:
A deflation of genetic information
ABSTRACT: It is often claimed there is information in some biological entity or process, most especially in genes. Genetic “information” refers to distinct notions, either of concrete properties of molecular bonds and catalysis, in which case it is little more than a periphrasis for correlation and causal relations between physical biological objects (molecules), or of abstract properties, in which case it is mind-dependent. When information plays a causal role, nothing is added to the account by calling it “information”. In short, if genetic information is concrete, it is causality. If it is abstract, it is in the head.
If accepted, it will be published in Acta Biotheoretica, but I expect some more review revisions.
This is my living room, so don't piss on the floor. I reserve the right to block users and delete any comments that are uncivil, spam or offensive to all. I have a broad tolerance, but don't test it, please.
Try to remain coherent, polite and put forward positive arguments if engaged in debate. There are plenty of places you can accuse people of being pedophilic communist sexist pigs; don't do it here.
Is Fodor really that bad? Bob thinks so http://bit.ly/anQRvz. I think that he must be making a different point, but philosophers can be dumb 19 hours ago
