Sanity Now Statistical

March 18th, 2009

Our modern tradition of trial-by-evidence is easy to take for granted. Having only just edged out trial-by-ordeal and gladiatorial combat to take its place amongst pillars of modern civilisation, it now attracts some suspicion when someone proposes that a person be convicted based on popular opinion, and this is a point which I may come to appreciate even more in my later life.

Politicians the world over, however, can have rather a poor grasp of the relationship between evidence and democracy. If I were to dedicate my time to documenting every instance of this in Australia, my server would probably collapse under the weight of the miniature black holes thus created. But Dr Dennis Jensen, Australian Federal Member for Tangney, has managed to be a little bit more offensive than usual for his rank (while still managing to maintain the level of mediocrity unique to Australian politics).

Try Harder

The trouble with searching for a PHP problem that affects your blog is that you find the other three million affected blogs and nothing else. But it did lead to this happy coincidence:

Except these. Not these ones.

Avatar

There’s this episode of Avatar in which the main characters come across an obviously phony fortune teller, and spend most of the time trying to make the villagers realise this. Laurie thought I’d find it funny.

Yes. Yes it can.

Science Show Audience Types

August 1st, 2007

An Introduction to Crowd Control

The science theatre can be a dangerous place. Between the tens of millions of volts leaping out of a Tesla coil, the hand-bleaching acetone and the neurotic theatre coordinator, theatre demonstrators have more than enough to worry about before they even leave their house in the morning (except for that last part). Science is a perilous enough activity without adding the general (ie. uneducated, unwashed, untagged, etc…) public to the beaker. Compounding matters by adding an audience is just asking for trouble.

The New Australian Citizenship Test

June 1st, 2007

In contrast to the usual coherent and rational political debate that forms the meaty substance of this country’s media reporting, we are occasionally served the starchy, rehashed sidedish of xenophobic controversy. This time around, we are (apparently) interested in adding a new condition — a test, in fact — to applying for citizenship.

No, not a nominal and ineffective ploy to garner votes from a population whose chances at such a test would be dubious at best — we’re above that. The test will look at Australian values. At morality. At political ideals. Where traditional entry requirements just examine the mind and body of a potential citizen, this test will examine their heart. And possibly wallet. But mainly heart.

Post-Positivism

August 20th, 2006

Originally from a Bad Science post asking about post-positivism…

[Tessa K]: positivism is the view that physical theories should only relate experimentally measurable — or even directly observable — quantities. For example, before the existence of atoms or molecules were verified, molecular theories of thermodynamics are not positivist.

Einstien worked in an environment very much influenced by positivists (like Mach), and you’ll note that his theories are very much oriented around observables (Heisenberg also).

POST-positivism comes after. With the advent of large, collaborative scientific endeavours (such as the Manhattan Project, Hollywood films and ridiculing P.T. Barnum until he made a lot of money), it was necessary to compile authoritative lists of things that could be measured. However, the question of whether the list itself could be experimentally verified to exist caused a great deal of consternation amongst the scientific community, leading to such famous quarrels as Russell’s paradox, the EPR paradox and Feynmann’s infamous “I know you are but what am I?” paradox.

Consequently, the list was split into four parts, each given to four little known physicists who died horrible deaths soon after. It is said that whoever finds and assembles the four parts will see the truth in whatever topic haunts them, shortly before dying a horrible death — making it a perfect present for that kid in the back seat who has just asked “are we there yet?” for the hundredth damn time.

What was the question?

That Look

May 15th, 2006

Last week, I bought a magazine from a homeless vendor…

Vendor: Cheers, mate. How’re you today?
Me: Yeah, not bad…
Vendor: Yeah, you’ve got that look — “not great, but I’m not gonna complain to the homeless guy…”

Intelligent Deformation

How can students do a lab on determining the Young’s modulus of a piece of wire and then not calculate the Young’s modulus! There is a step which says “From the gradient of your ‘increasing’ graph, determine the value of ε in the units N/m2

…And one of the students who completely neglected to calculate the Young’s modulus had a 6 word aim: “To find Young’s modulus of wire”

On 15/03/2006, at 3:31 PM, I wrote:
Perhaps they are protesting the attribution of the stretching of the wire to some simplistic physical principle. There are many details of wire-stretching that cannot be explained by current materials science, which indicates that the stretching is guided in some way — past and even present — by a more complex intelligence.

Maybe they feel that the idea of “Intelligent Deformation” should be given equal shrift in science education, rather than simply being dismissed as religiously motivated propaganda for another theory that, really, can’t explain the universe completely either.
