This exercise has some great questions to ask students in class that expose some very common misconceptions
I also use cards, but start with random mating (to show how starting from an unshuffled deck ->HWE), then start with non-random mating, then drift/migration, and finally selection (last, because otherwise everyone forgets the other forces)

Great thread on ret-conning obamas energy strategy and data on fossil fuel economics over the past two decades
This Yglesias piece in the NYT is horrifically bad. Almost every "fact" it cites is provably false. At best it is cocktail party banter from a pundit who knows nothing of energy. At worst, it was cut/paste from oil industry talking points. So, a rebuttal: www.nytimes.com/2025/12/18/o...

The one that works for me:
- a million seconds is ~11.5 days
- a billion seconds is ~31.7 years
- a trillion seconds is ~31,700 years
Big difference
- a million seconds is ~11.5 days
- a billion seconds is ~31.7 years
- a trillion seconds is ~31,700 years
Big difference
If people could just intuitively understand the difference between a million, a billion, and a trillion, we’d all be better off.
That applies to dollars. To tons of carbon. And so on.
Math. It matters.

Very useful thread on writing and interpreting promotion letters in academia
Great question!
1) First and foremost, we evaluate a candidate based on the departmental guidelines and expectations provided. We don't hold the candidate to arbitrary standards, or even to those of our own institution unless asked to do so. We assess the materials against the guidelines provided.

Dear senior profs who have written tenure letters.
Can you help demystify the process for some junior profs up for tenure soon?
What do you look for? How do you make your evaluation?
We are told that the letters are the most important part of the file, but not what letter writers look for.

Twitter accounts are based in Russia. BlueSky accounts are based in homes with, frankly, too many books, plants, obsolete cables, and pieces of rustic pottery, that could do with a bit of a tidying up, to be honest.

Yep, that's called "topworking"
Most of the big orchards that used to grow Red Delicious are now Gala, Honeycrisp, & Cosmic Crisp. And it's not because they cut the orchards down & started over! They just topworked the new varieties in & pruned out the branches of the older varieties.

Related question. If you have a honey crisp planted, can you cut the top off and graft a new variety on without giving the new variety the problems of honeycrisp?
