squareCircleZ on Biorhythms

In squareCircleZ » Trig graphs – how do you feel today?, Murray Bourne at squareCircleZ has a nice Flash gizmo to show biorhythm graphs and links to a site debunking their validity. Actually I think a nice lesson based on this would be to use a similar gizmo to support a demonstration of how sensitive the timing of coincidences between the different cycles is to small perturbations in their frequencies (most of those who experience biological cycles know that they usually aren’t entirely regular!). This might also lead to discussion of other more real biological cycles and periodicities – including nontrig ones like junebug and locust populations – and to the fact that astronomical regularities do have such unearthly precision that they can in fact be followed for many hundreds of cycles to make predictions about coincidences which are actually observed.

Someone else has also been working on layout. I’ll have to compare notes.

Harris in L.A.Times

This article by Sam Harris makes the point that “Within every faith one can see people arranged along a spectrum of belief.” and that “The problem is that wherever one stands on this continuum, one inadvertently shelters those who are more fanatical than oneself from criticism. Ordinary fundamentalist Christians, by maintaining that the Bible is the perfect word of God, inadvertently support the Dominionists — men and women who, by the millions, are quietly working to turn our country into a totalitarian theocracy reminiscent of John Calvin’s Geneva. Christian moderates, by their lingering attachment to the unique divinity of Jesus, protect the faith of fundamentalists from public scorn. Christian liberals — who aren’t sure what they believe but just love the experience of going to church occasionally — deny the moderates a proper collision with scientific rationality.”

What is missing is an attempt to answer the question why those in these outer circles believe as they do – and without that Harris is just preaching to the choir.

And it is neither effective nor true to assert that “there is not a person on Earth who has a good reason to believe that Jesus rose from the dead or that Muhammad spoke to the angel Gabriel in a cave”. For some a “good reason to believe” might not be based on reason (but might be just because it feels good) and for others it might be based on reason applied to misinformation (as when a usually reliable source lies to me I may later claim to have had good reason based on past experience to believe the lie).

Kudos to Fox News ?

Thanks to Theodore Labadie who posted the link on the ‘Transforming Langara’ listserv, but this is not surprising. The interview subject is promoting the purchase of “carbon offsets” and the opportunities for fraud in that are so magnificent that no self-respecting greedy mogul could possibly hold back for long.

Journalist Boasts of Anonymity

A Washington journalist announces that for a period of over 24 hours the only person who chose to read his free on-line bio with any care was a “self-appointed hall monitor”. If someone was paying me in the hope that others cared enough about my thoughts to buy papers to read them I might be less sanguine about drawing attention to this apparent lack of interest in me and my work.

Faces Just 6 Pixels Wide

This post by Stephen Downes presents an interesting link, but I don’t agree that it supports his thesis about human reasoning. Pattern recognition at this level is characteristic of many species and devices, and it’s a capability that is probably necessary for human reasoning whether or not such reasoning is based on rules and language.

In fact, it seems to me that if such a thing as distinctly human reasoning exists, then it shares many features with other more rudimentary forms of reasoning, but to say it is “based on” these is similar to saying it is based on biochemistry (or even physics if you want to go that far down into the foundations).

But if, as the base of human reasoning we are looking for  a characteristic which distinguishes it from other forms of reasoning, then language is not enough since it appears that language at some level is practiced by other species. Some people suggest that an awareness of contingency is key, but anyone who has watched a cat learning to control a mouse may be inclined to disagree. But unless Chimp research proves otherwise it may be that the language of contingency is unique to us (and perhaps also that of propositional truth though I suspect that a chimp who can lie to keep a friend from finding a treat might eventually be trained to recognize and label the lie of another). Failing that it may just be that the concept of a distinctly human form of reasoning is a mere conceit based on quantity or scale rather than anything qualitatively different.

BC-Alberta Trade Agreement Scuppers CO2 Reduction in BC

This Tyee Article about TILMA shows how its restrictions on differential regulation make it virtually impossible for one province to implement stricter standards (in any area).

Hours of Daylight

Thanks to Zac at squareCircleZ for pointing out the dawn and dusk graphs at Gaisma as real-life examples of approximate sine graphs.

In fact the true time of noon appears to oscillate slightly with a 6 month period so that the Tokyo graphs are modelled pretty well by 6+1.5sin(2pix/12)-0.15sin(2pix/6) & -6-1.5sin(2pix/12)-0.15sin(2pix/6).

(Update: thanks to zac also for pointing out in the comment below that I should either have used cosines or have said “where x is the number of months since the spring equinox”)

It will be neat to be able to give Gaisma as a source of reference data for the hours of daylight modelling examples in my precalculus classes.

Why I Have Not Read ‘Heat’

According to his publisher’s web blurb, George Monbiot has established that “we need a 90% cut in our emissions within 25 years if we are to stop ourselves reaching the point where the “climate feedback” becomes unstoppable”, and “for the first time, … explains how this cut could be achieved. ”

My problem is more with the latter than the former (although I am doubtful that the 90% cut can reliably to be shown to be either necessary or sufficient), and arises largely because the blurb reads to me like one for a secret ‘get rich quick’ scheme whose author will tell me how to make millions doing absolutely nothing in five easy steps (which just happen to be available only in book form).

If Monbiot can’t tell me in one page what the essence of his strategy is then he probably can’t do it in a book either. But just in case I’m missing out on hearing about the magic bullet that noone else has thought of I’ll be going to today’s seminar. And I urge anyone else at Langara who cares about the very real threat of global warming to do likewise.

Lights Out!

Unfortunately I don’t think this initiative has had enough publicity in this part of the world for there to be a noticeable dip as seen by BC Hydro but there’s nothing wrong with joining in to the extent that we are able.

It’s a shame that we are not using air conditioning at this time of year, but perhaps there are some other College-wide systems (other than computers) which could be temporarily shut down. And perhaps with regard to computers we could ask ICS to use those 5 min to test our emergency power supply system.

Of course if we wanted to send the strongest possible correct “signal” then we could start up the air conditioning and every available electric heater etc (arc welders would be good if we have them) earlier that morning then turn them all off at 10:55 and on again at 11:00 for another half hour or so (and off again at random times after that). But I suppose that might be seen as a cynical and dishonest manipulation of the data.
