So what makes a function a function? Well, there is all that stuff about the vertical line tests, and relationships, but there is a way to look at them through other systems that make more sense.

It is more likely than not that you have heard the words “domain” and “range” used to describe a…

Mysterious Mathematics - Foucault Pendulum

A Foucault pendulum is just like any other pendulum, nothing more than a weight attached to a wire; but to work well it needs to have a very long wire, with a really heavy weight. They’re often attached to the ceilings inside very tall buildings, such as museums and cathedrals, so that they can hang a great distance and swing impressively slowly. These sorts of locations also tend to have fairly constant temperatures, which avoids expansion and contraction of the pendulum which would cause complicated variations in its period.

What makes a Foucault pendulum different from a normal pendulum is that it is attached at the top to a universal joint which allows the pendulum to rotate freely around its fixing point as it swings. Once you set one in motion, its direction of swing will rotate at a rate of about 0.2 degrees every minute. But in fact, it isn’t really the pendulum that’s rotating: the pendulum is swinging back and forth in exactly the same direction. It’s the Earth which is rotating underneath the pendulum, which makes it appear that the pendulum is in fact changing direction.

At the North Pole, the pendulum would appear to rotate through a whole 360 degrees once a day, because the Earth rotates all the way round underneath it.

The rate of rotation of Foucault’s pendulum is pretty constant at any particular location, but in 1954, during an experiment with one, a physicist named Maurice Allais got a surprise. His experiment lasted for 30 days, and one of those days happened to be the day of a total solar eclipse. Instead of rotating at the usual rate, as it did for the other 29 days, his pendulum turned through an angle of 13.5 degrees within the space of just 14 minutes. This was particularly surprising as the experiment was conducted indoors, away from the sunlight, so there should have been no way the eclipse could affect it! But in 1959, when there was another eclipse, Allais saw exactly the same effect.

Many people have questioned his results: why should the eclipse affect a pendulum indoors in any way? Many subsequent experiments have taken place since, with mixed results: some experimenters have found no measurable effect, but slightly more have confirmed the result from several different locations, including an underground laboratory.

At the moment it is a true mystery: nobody has any real idea what the cause might be. Some suggestions have included gravitational waves, solar radiation, and the anisotropy of space (the fact that space is different in different directions). All of these physical phenomena are governed by highly complex mathematical models, and unravelling the mystery will take the combined efforts of mathematicians, physicists and astronomers the world over.

Teaching Simplicity: My math story:

“I always liked math, but it was always my most difficult subject (not that I did poorly, I just excelled at other subjects), the one I had to work hard and struggle at. There were times in geometry, calculus and algebra where I thought “this is so dumb, and it’s so tedious”. In college, I took…

Space-filling Curve

A space-filling curve is a curve whose zigzagging lines cover the entire space they occupy. They astound mathematicians because they seem as if they ought to be one-dimensional. After all, they are lines. However, as the curve reaches its limit, space filling curves occupy a two-dimensional space, becoming a completely filled figure.

The curves above were created using an L-system. An L-system is created by starting with an axiom, such as a line segment, and one or more production rules, which are statements such as “replace every line segment with a left turn, a line segment, a right turn, another segment…”. When this system is iterated several times, the result is often a complicated fractal curve. More.

““I compare myself with my former self, not with others. Not only that, I tend to compare my current self with the best I have been, which is when I have been midly manic. When I am my present “normal” self, I am far removed from when I have been my liveliest, most productive, most intense, most outgoing and effervescent. In sort, for myself, I am a hard act to follow.””

ugh. this is so wrong. how can you support someone letting their kid wear socks on grass. do you know how hard it is to wash those stains out?

I thought I was going to have to yell at someone for being a close minded asswipe but that was the biggest plot twist of my life.

but no seriously those stains are a bitch to get out
