Listening to this episode of 99% Invisible with Kid2 who's seriously annoyed with the Anglo journalists' French accent and the fact that they keep cutting off the Congolese interviewees to translate to English. "Why can't they just let them speak?" It's hard for the 8yo kid to understand that not everyone else is bilingual.

The Society of Ambiance Makers and Elegant Persons - 99% Invisible
Hailing from central African cities of Brazzaville and Kinshasa, sapeurs have become increasingly recognizable around the world. Since the 1970s, sapeurs (from: le sape, short for “Société des Ambianceurs et des Personnes Élégantes”) have been known for donning technicolored three-piece suits with flamboyant accessories like golden walking sticks and leopard-print fedoras, and then cat-walking through

Inside a vintage aerospace navigation computer of uncertain purpose
I recently obtained an aerospace computer from the early 1970s, apparently part of a navigation system. Aerospace computers are an interesti...

Realized last night - not sure why it took so long - that the Kamiokande-style neutrino detector is based on the same idea as the gamma-ray telescope I sketched out as a grad student, intended for launch on Compton but canceled by Reagan. Not taking credit for Kamiokande, the idea's not especially clever, but in the 1970s when I was a student it took some work to convince people it (timing the arrival of Cerenkov cones) could work. In the 80s it was easier.

Working to make our “sun room” look nice. Too chaotic rn but getting there.

We've been eating apples for thousands of years.
If someone suddenly wants to start putting people in prison for apple-eating, I'm gonna damned well state that I'm an old woman who remembers harmless apple eating from the 1970s, ...

The dimension of the region of feasible tournament profiles
Erd\H os, Lovász and Spencer showed in the late 1970s that the dimension of the region of $k$-vertex graph profiles, i.e., the region of feasible densities of $k$-vertex graphs in large graphs, is equal to the number of non-trivial connected graphs with at most $k$ vertices. We determine the dimension of the region of $k$-vertex tournament profiles. Our result, which explores an interesting connection to Lyndon words, yields that the dimension is much larger than just the number of strongly co…

Mexican Computers: A Brief Technical and Historical Overview
The emergence of the microprocessor in the early 1970s allowed the design of computers that did not require the substantial economic resources possessed by large computer companies of that era. Shortly after this event, a variety of computers based on microprocessors appeared in the United States and other developed countries. Unlike in those countries, where small and large companies developed most personal computers, in Mexico, the first microprocessor-based computers were designed within aca…
