I am working on a short video about Dimensions.

This is my script. Is it accurate? Does it convey the ideas well?

Hi! Let's learn about Dimensions

In Geometry we can have different dimensions.

Let us start with a point.

Can't see it? Well it has no size, so we will highlight it.


Now lets allow the point to move in one direction.

We get a line.

We need just one value to find a point on that line. So we have one dimension.

A line is one-dimensional.


Now lets allow the point to move in another direction. And we get a plane.

We need two values to find a point on that plane. So we have two dimensions. We call it 2D.

A 2D object is flat.

Circles, triangles, squares and more are two-dimensional.

We also call them plane shapes.


Now we let that point move in another completely different direction and we have three dimensions.

Spheres, cubes, cylinders and more are 3-dimensional.

We also call them solid shapes.


We can have more dimensions, but I can't draw them.

In Physics Time can be thought of as a dimension, but not in Geometry.

I wish I looked and sounded that good! That is Joe, he does voices.

Happy Christmas all!

November 23rd => 1,1,2,3

(But the sequence actually starts at 0)

Leonardo Pisano Bogollo, as well as being famous for the Fibonacci Sequence, helped spread Hindu-Arabic Numerals through Europe in place of Roman Numerals.

A page to help clear up any confusions people may have about Scalars Vectors and Matrices.

Corrections, suggestions please!

I decided to add a section on the worn logarithm book, and found that Simon Newcomb actually discovered that!

See my revised version (use refresh): First Digits Rule

Yes I heard that one too, and find it a fascinating example of how some people can notice things and go on to discoveries. But trying to explain what a log table is seemed a little hard for this page.

Great, will add : and define a Universal Set for the Complement example.

Has anyone else seen I used for irrationals?

A new page: Set Symbols

What do you guys think of it? Any mistakes?

Probably alerting you to subscriptions, but being blank means that something is not well configured. Hmmm.

Funny! But a good point, it would be nice to have one for BODMAS and BEDMAS.

A new page: Math vs Maths ... and more

Good page? Any mistakes? Do you have your own thoughts on this?

And any more examples for the second half would be appreciated.

Hi Bob,

Thanks for that, I will look into how I might be able to repeat the tabs in this version.

I think imgur (or the like) is the best solution for image hosting at the moment.

Every so often we get people asking lottery type questions, so I thought I would make a page to try to help them understand how chance works etc.

Here is my draft: The Lottery

I would value your feedback, any mistakes you may find, and any suggestions for inclusions.
