Hi!
Two years ago, I wrote a post about a physics competition — primarily for secondary school students, but there's also an open category intended for everyone. It took place last year too, I just didn't think about writing a blog post here.
If you like physics problems, go ahead and register on online.fyziklani.cz/en/!
UPD: Now with fixed registration.
Thanks for the reminder! I've participated a year ago remembering the two-year-old post and it was a huge fun! So I highly recommend everyone who likes physics and who likes competing to take part in this contest.
Good to know it was worth it to post here about a physics competition, I didn't know if I attracted anyone since it isn't programming and replies to my first blogpost were so scarce.
