#2The idea is interesting and the website is designed very nicely, but the subjects themselves are extremely lacking. For example the "level 22" Simple Harmonic wave is simply three graphs of a sine function with no other explanation. What is there to learn from that?

#3Well designed interface.
There might be something here if one can use this to render one's own notes? Or is this meant to render user provided content like Wikipedia?

#4Very nice website, but it would be tremendous undertaking to create content under all the topics. I would imagine another possible approach is to provide a short summary and a link to Wikipedia (or other sites) for detailed content. Presenting knowledge as a tree / web is always an attractive idea to me.

#6I don't understand the purpose, or rather, the comparative advantage of this website. It looks like a series of topics covered in the first few lectures of an undergraduate course in Fourier analysis (plus a few other topics). So why not just read a well-written Fourier analysis textbook? There's no motivation or coherence to this project, as far as I can see, just a collection of terse notes.

#7Neat and smooth GUI indeed, but like the other commenters I am not impressed by the contents.
The animated graph for instance in https://cognicull.com/en/8e2konlv that shows "If the width of the change stepwise in the time direction is narrowed as follows, it will be a very smooth curve. You can't see the change stepwise, but the last smooth curve is also a digital signal."
-> their bit depth is ALSO changing in their animated picture. So even if the text that follows further addresses that - they are completely missing the point of a good explanation with their illustration.

#8This is a good concept. Identifying what skills the student may lack if the lesson is difficult is a really good idea. It is missing from too many books in which the author just assume a student will be able to identify what he or she should learn to understand a specific topic.

#9Some other knowledge-graph type projects for comparison:
> Metacademy - "Package Manager for Knowledge" - https://metacademy.org/
> MathLingua - language for easily creating a collection of mathematical knowledge, including definitions, theorems, axioms, and conjectures, in a format designed to be easy and fun to read and write. - https://www.mathlingua.org/
> Learn X in Y minutes - https://learnxinyminutes.com/
> Learn X by doing Y - https://aquadzn.github.io/learn-x-by-doing-y/
> Awesome Lists - https://github.com/sindresorhus/awesome
> ncatlab - https://ncatlab.org/ - I visit the page I want to understand and make sure I understand the meaning of most of the hyperlinks in the first paragraph before I attempt to understand the rest
Many people are also starting to use the bidirectional-link style of note-taking to create their own knowledge graphs. I'm curious to see what sort of tools will emerge in the future to help people share the graphs they've created.
It's easy enough to find reading lists online for a topic, but one of the hardest things about learning a new subject, especially without the help of a teacher, is learning what NOT to spend time on and why.

#10Very nice! I appreciate also the multilingualism.
However, would it be possible to add an easy way to change language from the page of an article?
Right now to do that, I need to lookup the translation of the title and go back to the summary, which is not convenient.
