I got onto social media some years ago for two main reasons; to stay in touch with people I don't get to see frequently (which since the pandemic has been pretty much everyone), and to have a platform for marketing my books.
I'm the first to admit that I'm kind of awful at the latter. I hate marketing myself, and even though I know I won't be successful as an author if no one ever hears about my work, it goes against the years of childhood training in such winning strategies as "don't talk about yourself" and "don't brag" and (my favorite) "no one wants to hear about that" (usually applied to whatever my current main interest was).
I'm still on Facebook, Twitter, and Instagram, although for me the last-mentioned seems to mostly involve pics of my dog being cute. It strikes me on a daily basis, though, how quickly non-dog-pic social media can devolve into a morass of hatefulness -- Twitter seems especially bad in that regard -- and also that I have no clue how the algorithms work that decide for you what you should and should not look at. It's baffling to me that someone will post a fascinating link or trenchant commentary and get two "likes" and one retweet, and then someone else will post a pic of their lunch and it'll get shared far and wide.
So I haven't learned how to game the system, either to promote my books or to get a thousand retweets of a pic of my own lunch. Maybe my posts aren't angry enough. At least that seems to be the recommendation of a study at Yale University that was published last week in Science Advances, which found that expressions of moral outrage on Twitter are more often rewarded by likes and retweets than emotionally neutral ones.
Apparently, getting likes and retweets is the human equivalent of the bell ringing for Pavlov's dog. When our posts are shared, it gives us incentive to post others like them. And since political outrage gets responses, we tend to move in that direction over time. Worse still, the effect is strongest for people who are political moderates, meaning the suspicion a lot of us have had for a while -- that social media feeds polarization -- looks like it's spot-on."Our studies find that people with politically moderate friends and followers are more sensitive to social feedback that reinforces their outrage expressions,” said Yale professor of psychology Molly Crockett, who co-authored the study. "This suggests a mechanism for how moderate groups can become politically radicalized over time — the rewards of social media create positive feedback loops that exacerbate outrage... Amplification of moral outrage is a clear consequence of social media’s business model, which optimizes for user engagement. Given that moral outrage plays a crucial role in social and political change, we should be aware that tech companies, through the design of their platforms, have the ability to influence the success or failure of collective movements. Our data show that social media platforms do not merely reflect what is happening in society. Platforms create incentives that change how users react to political events over time."
I was an undergraduate when the original Cosmos, with Carl Sagan, was launched, and being a physics major and an astronomy buff, I was absolutely transfixed. Me and my co-nerd buddies looked forward to the new episode each week and eagerly discussed it the following day between classes. And one of the most famous lines from the show -- ask any Sagan devotee -- is, "If you want to make an apple pie from scratch, first you must invent the universe."
Sagan used this quip as a launching point into discussing the makeup of the universe on the atomic level, and where those atoms had come from -- some primordial, all the way to the Big Bang (hydrogen and helium), and the rest formed in the interiors of stars. (Giving rise to two of his other famous quotes: "We are made of star-stuff," and "We are a way for the universe to know itself.")
Since Sagan's tragic death in 1996 at the age of 62 from a rare blood cancer, astrophysics has continued to extend what we know about where everything comes from. And now, experimental physicist Harry Cliff has put together that knowledge in a package accessible to the non-scientist, and titled it How to Make an Apple Pie from Scratch: In Search of the Recipe for our Universe, From the Origin of Atoms to the Big Bang. It's a brilliant exposition of our latest understanding of the stuff that makes up apple pies, you, me, the planet, and the stars. If you want to know where the atoms that form the universe originated, or just want to have your mind blown, this is the book for you.
