Mom asked, "I wonder when cherries bloom in Japan?" So I found 1200 years of data online and made her a plot.

Have you ever noticed that the save icon is a floppy disk, even though they became obsolete twenty years ago? That's called a "skeuomorph" - when something new takes on the appearance of what it replaced. And once you start to look, they're everywhere...

“Maybe our ideals were not so out-of-date. Maybe our institutions were not so broken. Maybe the people the Ukrainians needed us to be, maybe those were the people we could be again.” @davidfrum on Ukraine, America, and how both need one another now. theatlantic.com/ideas/archiv…

The latest update to an important assessment found that populations had declined by an average of 69 percent since 1970. But that might not mean what you think.

What do cycling sponsors actually DO? Inspired by @BenjiNaesen, take part in @reardupeloton's poll - I have to admit I knew less than half of these. If in doubt, insurance, was my policy 😂

A thought on the the Tour de France Femmes and how you can do your bit to grow womens cycling. It’s simple. Watch. Shout about the coverage. Consume news coverage. Feed the algorithms, add to the data. Show the demand is there. This is our time.

I remember breaking down to my Ph.D. advisor about how stupid I felt while troubleshooting a problem in my project when she handed me this paper. Years later it is still relevant to young students starting off in Science. It's ok to feel stupid, we all do on a regular basis.
