Beginning in fall 2027, Penn Engineering and Oberlin College are launching a new partnership that will allow students to earn a bachelor’s degree from Oberlin and a Penn Engineering master’s degree in just five years The 4+1 partnership spans five fields, from biotechnology to energy and sustainability.

“Addressing complex challenges requires engineers who can bring together technical expertise, creative thinking, and an understanding of the broader world,” says Vijay Kumar, Nemirovsky Family Dean of Penn Engineering.

@DaletN_ai that's a good one!

the chapter lead figs in Elementary Applied Topology are amalgams of mathematical & literary images, sprinkled with my own pet theories on literature. this one, from "Sheaves" is based on the Inferno. there are three famous episodes of a pair of sinners, trapped:
* francesca & paolo : in wind
* ulysses & diomede : in flame
* ugolino & ruggieri : in ice
the sins & the sinners get progressively worse...
to this i added a fourth -- dante & virgil : in earth, then past satan, descending/ascending to escape up to the final image of stars...
this is a satisfying mapping onto the 4 elements (+ quintessence). did dante intend this? not clear, but it's a pretty clear pattern once you see it...

i use the "recorder" app on my pixel to record all my lectures. the transcripts are trash, yet when i upload it to a gemini notebook, it synthesizes the content near-perfectly... just record all the things & don't worry about source quality.

Drag-and-drop makes the digital graspable, but building it well is fiddly enough that many don’t bother. Declarative Dragging (with Josh Horowitz & Jeff Heer, #uist2026 best paper award), lets you make an element draggable just by listing the states dragging it can reach.

publication in mathematics may soon align with the humanities: the unit of progress is the definitive book -- not articles, not proofs -- but a comprehensive framing of and advance in a specific area of mathematics, the reading of which would be a slow educational journey.
