We’ve come to the end of yet another year, which is a good time to collect the blogging I’ve done over the last few months but not yet rounded up here.

—What Will Win The 2019 Nobel Prize In Physics? The annual guessing game. As usual, I lost.

—How The 2019 Nobel Prize In Physics Depends On Atomic Physics And How Lasers Can Do Better: Some thoughts on the spectroscopy needed to make radial-velocity detection of extrasolar planets work, and how frequency combs can improve that.

—Why You Should Give Thanks For These Three Quantum Phenomena: A seasonally appropriate ride on my quantum-in-everyday-life hobby horse.

—Decades And Discoveries: Defining The Eras Of Physics History: The first of several posts wrapping up the calendrical decade of the 2010s, setting up the idea of notional decades in physics like those that we talk about in pop culture.

—What Are The Physics Stories That Define The 2000s And 2010s?: The previous post stopped at the end of the 20th century, this one picks up where that left off.

—What Was The Most Important Physics Of 2019?: Wrapping up a single year this time.

—Three Physics Topics That Might Define The 2020s: Looking to the future, with the same notional decade framing as the previous posts.

This was a pretty frustrating stretch of blogging, to be honest; other than the Nobel stuff, none of these was particularly well read. I’m not super happy with most of them content-wise, either, because I was squeezing them in around a really hectic period of work and travel for various projects. That’s why I went nearly all of November without blogging at all, and I maybe should’ve taken a longer break.

Anyway, while I can’t be said to be heading into 2020 with any great blogging momentum, I can’t exactly stop it from arriving. So, like it or not, that’s a wrap on 2019 and we’re on to the next thing…
