Previously Tildes have had a few discussions on good quality Youtube channels one, two, but I couldn’t find a recent discussion.
I would be interested in peoples recommendations!
Personally I would like to get recommendations for intermediate/harder science or engineering videos. Most are too basic, or very dry lecture based. I know a few good ones like:

• 3blue1brown
• Smarter every day
• Looking Glass Universe

But I would like to know other people’s favourites (including non science ones)!

Me and my girlfriend will be in Paris for 2 nights soon. Since this is such a short trip, we'll mostly be visiting the most popular "essential" tourist attractions - so we will generally be around the center of the city. However, most advice I found online seems to agree that you probably shouldn't just enter a random restaurant in the center of Paris, because it is very likely to be a tourist trap with very high prices and relatively low quality.

So, if any of you have suggestions on good places to eat for a reasonable price, I would really appreciate that!

Also, the end of our trip happens to fall on valentine's day, and we were thinking about having a nice early dinner (late lunch? around 15:00) before we leave, preferably in a pretty place. I'm fine with spending a bit more (~50€ per person) on that one. So if you know any places that fit, please suggest those as well.

Thanks!
