Demisexual: Having sexual attraction only to people with whom one first develops a strong emotional connection

To clear up the most common misconception about demisexuality (i.e. that it’s not a real thing), it is necessary to draw a distinction between being attracted to someone and wanting to have sex with them: You may experience the visceral feeling of attraction on first sight (if you don’t, the entire porn industry is not a big fan of you) but on an intellectual level, you may not wish to actually perform sexual acts with that person. This is particularly evident for women, mainly due from the cultural expectation that men pursue sex from women and the women withhold it. This does not mean every western woman is demisexual. Even if you make an intellectual decision not to act on your sexual impulses, you still have those impulses. A demisexual person does not have sexual urges without having the emotional connection first.

Following up on yesterday’s Beautiful Math post, these are two illustrations from Guilio Troili’s treatise on the pantograph, which had been invented by astronomer Christoph Scheiner earlier in the 17th century.  A pantograph is a framework of parallelograms connecting two pens, one held by an artist, and the other reproducing the movements of the first pen.  Scheiner envisioned the pantograph as a device that could be used to enlarge a drawing at scale or produce a perspective drawing. Troili demonstrates both uses in this diagram, with cute cherubs as the artists.
