### LearnMathsFree - Free Maths YouTube Videos

I recently made a YouTube channel, Learn Maths Free, with the aim of creating video lectures (much in the style of KhanAcademy) on a variety of topics mainly at high-school level and undergraduate level.

At the moment, I've started a new playlist called Geometry and Groups, a course that loosely follows the syllabus of UCL's course*, that seeks to explore the fascinating links between group theory and geometry, starting with the Platonic solids and hopefully culminating in a discussion of the modular group, PSL(2,Z). More specifically, in this playlist I'd like to explore:

-Symmetry groups of Platonic solids
-Spherical and hyperbolic geometry
-A complete classification of Mobius transformations
-Isometries of hyperbolic space
-Euclidean space and quaternions

In the future (mostly dependent on popularity), I'd like to make videos on a number of other subjects, such as, GCSE Maths, AS and A-level Maths, SAT prep, Topology, Number Theory, Partial Differential Equations, Group Theory, Linear Algebra, Calculus, Real and Complex Analysis, Elliptic Curves, Fluid Mechanics.

*Taught in 2014-2015.

Videos so far:

EDIT 2: For the past couple of weeks, the above links were not functional. They are now fixed, as of the 1st of October, 2015.

Sounds excellent!  I am limited to my kindle at the moment.  I will check it out properly tomorrow.

Hi;

In mathematics, you don't understand things. You just get used to them.

### Re: LearnMathsFree - Free Maths YouTube Videos

Yes, it's my channel. I've only got a handful of videos at the moment but more is coming soon, and am open to requests.

I was thinking of using it to also potentially answer problems from the Help Me forum.

You should have told me sooner, I will want to look at the videos as soon as the weather here clears. The rain is coming and I will be blacked out.

It has broken down to just a T-storm, still 2 - 4 inches of rain will fall on my area. This will cause flooding and power outages.

Good luck on your channel, Zetafunc. I just subbed.

Suggestion: I believe you should watermark your video.

Thanks. I may put a watermark in future -- perhaps if it becomes more popular.

I always thought they were cool, too. They were not so popular among my peers, however.

Number Theory was not too popular last year. It's difficult to gauge what people like on my course -- often 'easy' would be equated with enjoyment. In which case, everyone loves PDEs.

Hmmm, never thought I would see the day that number theory went belly up.

While I really think that this is an excellent effort, I would comment that you could have named your channel better

### Re: LearnMathsFree - Free Maths YouTube Videos

I would have to agree with you. Truth be told, this is sort of a placeholder name while I think or something a little more creative. One disadvantage of this name is that it's terrible for Google searches: googling "learnmathsfree" will instantly return search results for "learn maths free" (with spaces), which my videos cannot compete with.

hi zetafunc,

Great start!  It will take me a while to view all of these ... then I may have a request.
