Did you know that Lawvere [famous category theorist] did classified work on arms control in the 1960s, back when he was writing his thesis? Did you know that the French government offered him a job in military intelligence?

第二ボタン (daini botann) refers to the second button from the top on a shirt or a jacket. In Japan, a graduating boy gives this second button on their school uniform to a girl he likes. This usually occurs at or immediately after a high school graduation ceremony, when the boy threads the button out of his shirt and gives it to a (usually younger) girl, for whom the gift of this button is considered a tremendous honor.

Interesting ritual I found in a manga one shot today.

Many of my monosexual friends have attempted to turn themselves bisexual. This is a post on the success rates.

Overly serious blog post on one of the most inane “movements” I’ve read about in recent memory. The post uses the Kinsey scale to describe sexuality (light bleh), but then also casually does some of the best queering of masc attraction I’ve ever read. Roller coaster.

Transfeminine Science is a resource for original informational content on the subject of transfeminine hormone therapy. This form of hormone therapy is also known variously as feminizing hormone therapy (FHT), gender-affirming hormone therapy (GAHT) for transfeminine people, and, more in the past, male-to-female (MtF) hormone replacement therapy (HRT). It involves the use of female sex hormones including estrogens and progestogens, as well as androgen-opposing medications known as antiandrogens, to produce feminization, demasculinization, alleviation of gender dysphoria, and other changes in transgender women and non-binary transfeminine individuals.

Why do facts bounce off some people? It’s not about logic; it’s about structure. Your worldview isn’t a list of opinions—it’s a living network. And right now, it’s at war.

When you are arguing with someone who is deeply embedded in a different belief graph, you’re not just trying to change one opinion. You’re engaging with a network of ideas that is stabilized by powerful psychological mechanisms.

Although we at the Topos Institute spend much of our days applying category theory, underlying our activities is a philosophy around the activity of science and engineering that is not explicitly category-theoretic in nature. In this blog post, we lay out some of the core ideas of this philosophy, and tie them in to current and future research developments at Topos.
