Wow, what a plan! I can imagine this will indeed keep you over-busy fr the rest of the year. I have quickly checked the Udemy course, and what you point in there is exactly what is badly mastered by students entering university. Trigonometry is hard, vectors are often very obscure and I don't even talk about complex numbers. High school is not what it was anymore, at least in France.

I hope to read from you on Steem once in a while, but I understand time is the problem. The same holds for me, where usually, I post only once a week. Sometimes twice, but this is rarer. I am afraid I have no trick to share here... :/

In my case, I am currently overwhelmed by the new term at Sorbonne. I am the head of the bachelor 2 physics studies, which means I am currently registering students, checking that all courses are smoothly starting, etc... I hope to free some time to resume research in a couple of weeks. I am planning to finish 4 articles this summer, 1 being the milestone of something I started at CERN in 2013. And of course, I will travel for work: Florence (the steemstem meetup), Freiburg, Odense, Daejeong, probably Montreal, Granada, Hefei, Tokyo and Kruger are on the program. And then a Xmas break at home :D
