May 6, 2026 — Today is National Nurses Day, which recognizes work that often happens in the background but matters in a very real way.

Today we’re looking at a few moments where expectations shifted quickly.

First, the Hindenburg disaster in 1937, and how a single event changed public trust in an entire form of travel.

Then, the introduction of the iMac in 1998, which helped reshape how computers were designed and experienced.

And finally, the final episode of Friends in 2004, a moment that brought millions of people together at the same time.

Plus, a look at Sigmund Freud, whose ideas changed how people think about behavior and the mind.

It raises a question about how quickly perception can change once something shifts.

Anyway… that’s what I ended up finding while working through May 6.
