Cuando yo estudiaba y el breve intervalo en el que trabajé en la Complutense, se impedía el acceso de la policía salvo petición expresa del rector en casos excepcionales. Por ejemplo, nunca cuando se ocupó mi facultad. ¿Qué ha cambiado para ver semejante abuso en mi antiguo campus?

My latest cartoon for @newscientist.com
As we join the great theoretical scientist, he is deep in thought. So still, quiet and focused that he might almost be asleep. But inside that brilliant mind, what new idea is forming? What certainty is being meticulously interrogated? What ingenious theory is ready to change our world forever? (the scientist snores lightly) Ah, it seems he actually is asleep. And that's fine. Science is hard and not every day can be a success. We will come back another time.

Four days ago, a scientist was surprised by the news that Anthropic discovered new virus genes for making DNA. He says he’s been studying them for years—and feeding his data to Anthropic’s AI as part of his own research. Coincidence? Here’s my story. nyti.ms/3VSWayc

Did Anthropic’s A.I. Really Make a Scientific Discovery on Its Own? (Gift Article)
An expert at the University of Copenhagen said his team had been sharing its research with the company’s A.I. model, Claude, and that its new finding matched their work.

Terrible joke meme made of 3 stacked images from a moving scene in the film Finding Neverland.
1. Close up of a young boy (Freddy Highmore) sitting on a park bench with his father looks up at him and says "Dad, can you tell me what a solar eclipse is?" 
Image 2: Close-up of the dad (Johnny Depp) looking down at his son saying "No Sun" 
Image 3: the father embraces the boy as they sit on a bench. The boy is crying at the dad joke.

How do you tell whether a variational quantum architecture makes good use of expensive quantum resources? Watch the animation: as κ is swept, the curves collapse onto a single universal curve. That collapse measures how efficiently circuit depth becomes long-range physics. 🧵 1/10
