Phase Shift

Saturday, December 30th, 2006

Phase, Frequency, Amplitude, and all that.. is an example of a university math course adopting the convention that identifies "phase shift" as angular shift as opposed to horizontal displacement or "time shift" And at the time of this posting, the Wikipedia article on Phase (waves) takes the same point of view.

Phase Shift or Phase Angle?

Saturday, December 30th, 2006

Murray Bourne at squareCircelZ has taken the time to respond to a comment I made on one of his interactive math pages, so I thought I should make an effort to explain my concern in a bit more detail. In high school and college precalculus courses, the material on graphing trig functions often includes a […]

Carbon Footprint

Sunday, December 24th, 2006

Carbon Footprint includes a "calculator" for estimating one's personal contribution of CO2 to the atmosphere and suggests various ways of reducing or offsetting it. But the encouragement to "plant trees" (or pay for same) may be misguided, since it seems clear that it is the lifetime carbon sequestration that is being assigned for each tree […]

Will at Work Learning: People remember 10%, 20%...Oh Really?

Wednesday, December 20th, 2006

This post by Will Thalheimer came to my attention via Harold Jarche and Stephen Downes. Unfortunately it's not just in education that people are often impressed by fraudeulent mis-citation of derivative bunk.

Wrong Problem, Wrong Solution

Tuesday, December 19th, 2006

This posting by Roger Shank (found via Stephen Downes) uses widespread ignorance of the quadratic formula by successful people as evidence that mathematics requirements in our schools are excessive. But I know that in BC it is quite possible to graduate from high school without knowing the quadratic formula. So, unless this jurisdiction is more […]

More on Religion

Friday, December 1st, 2006

My experience may include something equivalent to what others call god, but whatever it is cannot be put into words - perhaps not at all, and certainly not with the certainty that most religions ascribe to their own very specific creeds and scriptures. Indeed, the conflict and hate that arises between these competing creeds is […]

My main reason for posting about this from David Brin is to see if any qualified comments come back on the feasibility of subductive disposal.

How Can Smart People Believe in God?

Friday, December 1st, 2006

How Can Smart People Believe in God? is a blog entry at Stanford's 'Philosophy Talk' about their Oct 22 show with Philip Clayton on 'Believing in God'. Commenter David Chilstrom revives the old saw that it takes as much faith to disbelieve than to believe - completely missing the point that not to believe in […]
