11:18 PM | The turd and the bean, or: the strange life of male nerddom under patriarchy
Everybody’s talking about Laurie Penny’s awesome essay responding to Scott Aaronson’s courageously candid blog comment, all touched off by the canceling of Walter Lewin’s online course after he sexually harrassed one of the students. Scott is frustrated that shy, nerdy men are seen as “privileged.”  He thinks they’re the opposite of privileged.  I don’t see things […]

11:15 PM | the slow regard of silent things
As mentioned previously, I first bought this book thinking it was the third and final volume in the Kingkiller’s Chronicles. Hence I was more than disappointed when Dan warned me that it was instead a side-story about Auri, an important but still secondary character in the story. More than disappointed as I thought Patrick Rothfuss […]

11:01 PM | The deadly irony of gunpowder
In the mid-ninth century, Chinese chemists, hard at work on an immortality potion, instead invented gunpowder.

1:44 PM | Claudio Cavalleri e il Collegio per i Nobili
All'inizio del XVIII secolo i fratelli sacerdoti parabiaghesi Don Claudio I Cavalleri e Don Carlo Filippo Cavalleri, entrambi di costituzione fragile e salute cagionevole, sotto l'egida protettrice dell'agiato padre, aprirono un Collegio Convitto riservato all'istruzione dei giovani rampolli della nobiltà milanese e lombarda. L'anno di fondazione appare incerto: secondo l'Archivio dello Stato di Milano risalirebbe al 1700, mentre lo storico Alessandro Giulini posticipa la data tra il […]

From Zero to One: Eroom’s law — that’s Moore’s law backward — observes that the number of new drugs approved per billion dollars spent on R&D has halved every nine years since 1950.

11:14 PM | foie gras fois trois
As New Year’s Eve celebrations are getting quite near, newspapers once again focus on related issues, from the shortage of truffles, to the size of champagne bubbles, to the prohibition of foie gras. Today, I noticed an headline in Le Monde about a “huge increase in French people against force-fed geese and ducks: 3% more […]
