It's amazing what you can do with math and pixel measurements! Thank you for doing this! This information was usefull for me.



To answer your questions, I say that this presentation was quite glear to me. Also those little jokes (such as "thanks Twi") were freshing and helped me to keep the focus on the math. (I'm not a math-person myself, I only have a small capability to understand it in some low level.) You asked was there any flaws/good things in you presentation's texts and as an amateur writer (I have been writing actively for 3-4 years now) I can say this:



There was enough text to understand and it was short enough so that I didn't get bored. It was interesting and (as I said before) clear and understandable. The only tip that I could give to you, is to avoid too long senceteces. Short sentences make it easier to read. This wasn't really a proplem but I'm still saying it so you don't fall on that trap so to speak. I am very aware that in mathematical explanation it is really hard. (And as you can see, I tend to write long sencetensies myself.) So more like, you would try to make sure that there isn't too many long sentences after another. Overall, it was very good.
