How is that?
Having passed a difficult path from a graduate of the Faculty of Radiophysics, through an employee of a state scientific institution, a teacher of an author's special course in my beloved alma mater, I finally became a respected employee of the R&D department of a very cool startup in the field of augmented reality .
Cool company, cool tasks, busy schedule, great conditions and pay ... but after working at the research institute, where are you sitting in a laboratory with the same abnormal mathematically educated people who understand your stream of consciousness perfectly, it turned out to be difficult to contact non-mathematicians. You tell them seemingly simple and obvious things, like “did you check the data for homoscedasticity?”, And they ask you not to express yourself in front of girls. Yes, and the teaching past did not let me go ... In short, I became an active participant in intra-corporate knowledge sharing. And from some point, he even began to lead a small group in mathematics.
At the moment, the guys have already “graduated”.
Of course, they have not yet become data scientists in R&D, but it has become much easier for them to understand what mathematicians are talking about in their own language. If desired, they will be able to continue their education on their own or through video courses. The main task, which, it seems to me, was successfully solved in our courses, is to show people that mathematics is not at all as difficult and scary as it seems at first glance. You just need to get used to a specific way of thinking: unfolding chains of logical reasoning.
He came for me...
Someone gave my appearances and passwords to Lex from the channel : )
As a result, I, a simple proletarian of intellectual labor, unexpectedly became the hero of the plot on this cool channel!
There were comments, there were questions… It turned out that people are interested in mathematics. It turned out that people would like to learn (in the vast majority of cases, I think, repeat what they have learned :)).
At first, I was not going to make a video blog on mathematics, I decided to just record a video consultation for those who decided to embark on the path of self-education.
But it took some time and I realized that I want this! And I decided not to resist my unsatisfied teaching desire 🙂

The channel could have started its existence 2 weeks earlier if it weren't for lighting problems... Since I record videos in the evenings, I need a fairly powerful stream of artificial light. And since there was no money yet for professional equipment, I had to engineer a lighting installation from improvised material. And put a lot of light bulbs in there. And it turned out to be crap. It turned out that a large number of point light sources give a large number of shadows 🙂 But it was possible to refine the design to a relatively shadowless version by simply replacing point sources with linear ones.
So what is the channel about?
The channel has short (up to 20 minutes) video lectures.
There will be 3 large sections in total: A) mathematics, B) data processing and analysis (there will also be about image processing) and C) machine learning.
Sections B) and C) will be provided with lectures on implementing the studied algorithms in Python, using NumPy, ScikitLearn, Pandas, etc.
The mathematical section will include all the mathematical base that is necessary for sections B) and C), and from the very beginning. Since I declare the availability of mathematics to everyone, we will begin with a brief recap of the very basics.
At the moment (5 weeks from the start) the first block "Introduction to Mathematics" has ended. In this block, we briefly repeated the school arithmetic course, remembered all the properties of degrees, LCM, GCD, fractions, abbreviated multiplication formulas, etc.
The second block has started, it is dedicated to sets and logical operations. Mathematics is not at all from the school curriculum, but it is not more difficult!
And then there will be many more interesting things: again repeating the school curriculum in algebra and geometry, trigonometry, a smooth transition to the complex plane, derivatives and integrals, linear algebra, spectral analysis, differential equations, analytic geometry, probability theory ...
