Some people like vintage cars, others like vintage computers, I like vintage microscopes.
I just received my AO Spencer Series 4 microscope. It's in good shape, and I got it because I don't see Series 4 models around much. Now that I have it though, I question the wisdom of my choice because I need to clean and adjust a few things but I can't find a manual for it anywhere.
There's a great microscope support group over at Microbe Hunter, so if you're into microscopy of any sort, you should take a look and consider joining their forum.
About the Manual
The Nerd Manual is meant to be both a useful resource for nerds and a guide for the people involved with nerds. If you're a nerd you can find information here that will help you improve your life and perhaps better understand yourself. If you're close friends with, dating, or married to a nerd, I want to give you insight into things nerds do that a lot of people have difficulty understanding.
I hope to avoid offending anyone--either nerd or non-nerd--but please understand that the manual will get into some sensitive topics, stray into contentious territories, and even use stereotypes to illustrate points. It's OK to disagree with something, but keep your comments civil.

Real Life Nerds: World Record Spaghetti Marshmallow Tower
![]() |
| u/codesherpa's tower |
The tower challenge can be seen in Skillman's TED talk, but the rules are pretty simple:
in eighteen minutes, teams must build the tallest free-standing structure out of 20 sticks of spaghetti, one meter of tape, one meter of string, and one marshmallow. The marshmallow needs to be on top. (codesherpa is working at a slight disadvantage because he's using yards instead of meters, so his materials are a bit restricted.)
Taking the challenge seriously, codesherpa went home and tested ten varieties of spaghetti to determine which is the sturdiest, and engineered a design that maximized the structural integrity of his limited resources. If you read through the comments, codesherpa also explains the other different designs he tried, and the difficulties of working with a cat.
What makes this such a nerdy reddit post isn't so much the spaghetti tower, although that's certainly an enjoyable part of it, but it's codesherpa's attention to detail, meticulous planning, application of engineering knowledge, and iterative testing to accomplish a completely frivolous task. It's a delight to read the initial post and the discussion between users in the comments, and I think the world is better for having people like codesherpa who are willing to share nerdy experiments like this.

Who Knew the Air Force is the US Military's Transistorpunk Holdout
![]() |
| Launch Control - US National Park Service |
While the Air Force said goodbye to the 8-inch floppy drives they used for data storage in October of 2019, it appears that the rest of the system is still in place.
In an age when a fitness tracker has more computing grunt than the Air Force communications system, it seems kind of...risky to rely on a computer system from the era of disco, but Lt. Col. Jason Rossi jokes, "it's the age that provides that security. You can't hack something that doesn't have an IP address."
If you're good with old systems, and don't want to enlist, the Air Force relies on both active-duty and civilian personnel to keep SACCS operational. “I have guys in here who have circuits, diodes, and resisters memorized,” Rossi says. “They can tell you what’s wrong just based on a fault code or something. That level of expertise is very hard to replace.”
When something breaks on a current computer system, standard practice is to throw it out and replace it, but on SACCS the components have to be repaired, which could mean spending hours spent on a microscope repairing a circuit board.
On a related note, Air Force programmers keep the SACCS software up to date with regular revisions to the code. In order to keep the programmers in touch with current development, the 595th sends its airmen to development hubs with appropriately nerdy names like Kessel Run and Kobayashi Maru.

The Great Literary Guide Has Left Us
Harold Bloom, the literary critic whose melancholic visage graces a vast collection of literary guides in libraries around the world, died on Monday at the age of 89. He was still teaching his class at Yale University up until a few days earlier.
Certainly Bloom carried his share of notoriety for defending the great white literary canon--Plato, Shakespeare, Chaucer, Emerson etc--and his reference to the multicultural literary movement as “the School of Resentment”, but he was one of the most passionate literary critics of the twentieth and twenty-first centuries, and definitely the most well known. His name and face (forehead perpetually propped in one hand) adorn 600 or so guides to literature--collections of critical articles from a vast array of critics, across multiple centuries, covering everything from understanding individual characters, to teaching and writing about a huge swath of literature. He authored 40 well-received books of his own, including two this year and another due out soon.
There are those who dismiss Bloom's canon as too Western, and highly subject to his personal whims, and perhaps he would agree. Bloom believed that aesthetics were paramount in literature, proposing that, “the canonical quality comes out of strangeness, comes out of the idiosyncratic, comes out of originality."
However, he lamented the fate of the university English departments, fearing that they "will be renamed departments of ‘Cultural Studies, where Batman comics, Mormon theme parks, television, movies and rock will replace Chaucer, Shakespeare, Milton, Wordsworth and Wallace Stevens."
I hope he left us his map.
