As the US approaches 250 years, Jill Lepore’s These Truths offers a one-volume overview of those years. Focuses on key themes and figures in a long but enjoyable read. She just launched a new book on the US Constitution in case you need even more history.

Dragon Boat racing today: how it started (rains this morning) and how it ended (finals races cancelled due to winds and waves). We did have two races in between, racing in synch and enjoying a full day. Some 44 boats, and even retirees coming back just to help out. I am sapped.

I recently spent a week in Munich with my oldest daughter, who finished her 3rd year in university. I feel grateful to have such opportunities, and while we enjoyed some amazing sites and experiences. A few highlights, including the all-important pretzel.

Next year the US will celebrate 250 years since independence. Last night I attended a panel on the “Meck Dec”: the claim is that a few folks declared independence in May 1775 in what’s now Charlotte. There’s no smoking gun to support or refute the claim. But an interesting case of public history.

LLMs produce funnier memes than the average human, as judged by humans. Humans working with AI get no boost (a finding that is coming up often in AI-creativity work) The best human memers still beat AI, however. arxiv.org/abs/2501.11433

This is the story behind a viral retirement ad: The agency: “It was easy to do the math. We took the average rate of inflation and extrapolated out thirty years. Then we wrote the ad. It was attention-getting. It was informative. It spurred people to act.” #retirement #inflation
We started with our target audience: The advertisers realized if they simply promoted TIAA-CREF's retirement services, people wouldn't take action. They needed to overcome people's procrastination, and inspire them to take action now. https://buff.ly/4f0OlKS #ads #finance #TIAA #agencies #marketing
This 30-Year-Old Ad Predicted Life Today, and Keeps Going Viral. Here's How Its Creators Made It | Entrepreneur
This TIAA-CREF ad was shockingly accurate. Its makers said they didn't want to commit "advertising malpractice."

Popcorn and movie theaters are inseparable today. But did you know that a century ago, cinemas actually banned popcorn?
A Kansas City saleswoman named Julia Braden became one of the first vendors to talk her way inside the lobby — and built a concession empire in the middle of the Depression.
