A big part of my tweets are inspired by other people's content.

I bookmark everything that looks interesting and go there when in need of inspiration.

This is a thread-recap of the best-saved tweets from 2020 (for me at least) and what you can steal from each one. 🧵👇

So regarding to my "bombshell"...it's perhaps a bit less dramatic than many presumed, yet it still troubles me a lot, to the point that I wondered whether I should stop posting on certain things


You see, I realized in the last few months that, by translating information and news related to one of the fastest growing spaceflight powers of the world...I inadvertently became a spreader of PRC propaganda.

And with me exactly 180 degrees away from them, I feel scared.

It actually started a few years ago - it's not hard to meet Chinese Twitter users interested in spaceflight, either those living overseas or find a way to climb over the wall. Not surprisingly, many of these S/F enthusiasts are interested in their own military too.

This steadily grew with my followers' count until the flagship Chinese spaceflight missions of 2020 (Chang'e 5 especially but also many others) brought in dozens of them liking/re-tweeting my info tweets sometimes, and similar no. of such followers every month.

I do casually check these new followers/users sometimes. To my horror, far too many of them routinely insults, attacks, mocks others who they see as "anti-China" or spread potential mis-information, even blatant attacks, that started off w/ their state media/spokesperson.
Hey #optics and #photonics twitter

It's time again for the 2nd annual #top10photonics thread, where I compile my own #top10 best photonics papers list of the year!

See here for last year's thread:

Same disclaimers as last time:
1. These aren't just papers that were published in 2020. They are papers that were added to my library in 2020. Some are a little older — some are a lot older. All are interesting or exciting to me in some way.

2. I reiterate - TO ME. This list is highly subjective, and is mostly about what captured my imagination most, not about what will make the biggest impact, or what is most worth funding. The order is mostly arbitrary too. This is just for fun :)

3. Once again I am NOT including any of my papers, or any from my current or former groups. If you're curious about what I do, drop a proverbial tip in my jar and peruse my publication list

And while I have your attention, register for #POM20ja, happening in 2 weeks. (It's free!) It's a completely reinvented @PhotonicsMeetup, and it promises to be a great time!

Now, on to the main event!
