Monkey Launching Capability

First place I saw this didn’t mention what the combustion reaction was, but via kottke:

If you mix calcium carbide and water, it produces acetylene. Acetylene is extremely flammable and can launch 55-gallon drums into the air when ignited.

Don't Take a Slice of My Pachyrhinosaurus lakustai

Canada’s New Quarters Will Have Glow-in-the-Dark Dinosaurs on Them

Each of the quarters, which will retail for $29.99, will feature an image of a Pachyrhinosaurus lakustai, a dinosaur discovered in Alberta. But take it into the closet under the stairs or wherever your favored glow-in-the-dark viewing site is, and the creature’s skeleton glows.

But hey, we have presidential dollars that you can buy for $2. And they’re invisible. You don’t see any in circulation, do you?

If Only Certain Journalists Could Be so Persuasive

Warm spring weather and global warming: If only scientists could be so persuasive

Gah. What an unconvincing piece of tripe, which is too bad, because the message itself has a lot of merit.

It’s true that the recent warm winter weather has softened the American public’s stance on global warming, and that a colder winter has/will make them more reluctant to accept. This shows the lack of scientific literacy, in the form of a basic scientific disconnect between weather and climate, that the average person has. It’s also true that scientists should do more in the form of outreach. It’s too bad the article doesn’t connect how the latter would affect the former.

Generally, those who know the most about climate – and other important scientific fields – are locked up in their university ivory towers and conference rooms, speaking a language only they can understand.

And they speak mostly to each other, not to the general public, policymakers, or business people – not to those who can actually make things happen.

This is dangerous. We live in an age when scientific issues permeate our social, economic, and political culture. People must be educated about science and the scientific process if we are to make rational and informed decisions that affect our future. Indeed, a well functioning democracy requires it.

But instead, the relative absence of academics and academic scholarship in the public discourse creates a vacuum into which uninformed, wrong, and downright destructive viewpoints get voiced and take hold.

There are several scientists who are quite vocal in explaining climate change. And what do they get for their trouble? The get verbally attacked and threatened with violence, they get their emails hacked, and the people who have already decided that global warming is a fraud or hoax go right on believing so. The denialist camp can trot out a few “experts” to counter anything that is said in support of climate change, and the discussion is couched in language that subverts the process of science (such as the implication that having any level of uncertainty is a failure, or that because we don’t know everything that we know nothing) The press is complicit in this when they present a false balance to the story by presenting both sides of the issue, giving the impression that the scientists are split equally.

Scientific literacy through general education is another requirement that scientists can’t directly affect, either. You can lead a horse to water, and all that — if you don’t speak the language, any effort to explain details is wasted, but that’s not to say that the attempts aren’t being made. A big problem here is that the average (scientifically illiterate) person can’t tell if it’s shit or shinola — they see or hear some word salad and they think it’s the real deal. And they aren’t motivated to go and learn anything. That, however, is one avenue where outreach can help — getting people excited about science, and getting them to want to become literate.

Which means that people have to make an effort to meet scientists halfway, and improving that requires a very broad effort. It’s not something you can simply blame on scientists residing in their “ivory towers”. But that’s an uphill battle, because if parents don’t value education and scientific literacy, it probably means their kids won’t get the exposure that they need.

Where You Can't Toss One Down

Space station used for Ardbeg distillery experiments

Experiments using malt from the Ardbeg distillery on Islay are being carried out on the International Space Station to see how it matures without gravity.

Compounds of unmatured malt were sent to the station in an unmanned cargo spacecraft in October last year, along with particles of charred oak.

Scientists want to understand how they interact at close to zero gravity.

We Are Killers of Bliss

Laughter as Medicine: The Origin of a Meme

As any good science skeptic/happiness buzzkiller can immediately discern, this is bullshit. But are we Dementors or are we teachers? No, we are not here solely to suck the happiness out of the internet. We are defenders of reason and illuminators of the obscure.

I think this goes beyond “someone is wrong on the internet”. Geeks place a high value on correct information and especially so in cases like this: a medical tidbit. Perpetuating an urban legend with no basis in fact, on which people might base decisions that affect their health, can be dangerous. Steering people down a certain path might mean that they avoid legitimate treatment. I remember harrumphing at some comment at a family gathering, where somebody had mention some sham treatment (I don’t recall if it was homeopathic, or copper bracelets, or magnets or what) and was challenged with “What’s the harm?” The harm is in thinking this will work, and so you don’t consult an actual doctor with actual diagnostic ability and the ability to prescribe scientifically tested medications and treat you in ways that are proven to work better than doing nothing. And delaying that does harm.

Even when the outcomes are not potentially as dire as illness, you may still base decisions on these nuggets of anti-truth, and that’s not good. So yes, we are trying to stamp out ignorance, and since ignorance is bliss, it might seem like we suck all the fun out of the internet. So be it.

Where in the World are Henry David Thoreau's Plants?

Where Are Henry David Thoreau’s Plants Now?

[Thoreau’s] journals offer an unparalleled phenological record — that is, a log of the timing of events, like a first flower or leaf growth. Looking back through Thoreau’s logs, as well as those of later botanists, Primack and Miller-Rushing found the first flowering date for 43 of the most common species has moved up by an average of 10 days.

A Day at the Mad Science Fair

“Teratogenic Effects of Pure Evil in Ursus Teddius Domesticus.”

Winning entry in the Mad Science Fair by Dr. Allison von Lonsdale of the Institute for Dangerous Research.

1. A sample of Pure Evil was obtained from the ruins o f an exploded toaster in the south of England.

2. Pure Evil was administered, via drinking water, to pregnant laboratory teddy bears for the duration of their pregnancy (4 months).

3. Dosage varied from 0 parts per million (ppm) to 1000ppm, titrating upwards by steps of 100pm.

4. Offspring were euthanized and mounted for display.
