Super-Kamiokande
 |
| Image of the Sun taken at Night |
The whiz kids are constructing a mythological universe, more bizarre than anything Tolkien ever dreamed of. This is an image of neutrinos directly emitted from the core of the Sun, obtained by the Super-Kamiokande neutrino detector. Well, that's what the whiz kids say. I suspect it's a glitch in the matrix.

| A model of KamiokaNDE |
Super-Kamiokande is located 3,300 feet underground in the Mozumi Mine in Hida's Kamioka area [Japan]. It consists of a cylindrical stainless steel tank 136 feet tall and 129 feet in diameter holding 55,360 tons of ultrapure water. The tank volume is divided by a stainless steel superstructure into an inner detector (ID) region and outer detector (OD). Lining the inner detector are 11,146 photomultiplier tubes (PMT), each 20 inches in diameter, that face the ID and (1,885) 8 inch PMTs that face the OD. A Tyvek and blacksheet barrier attached to the superstructure optically separates the ID and OD. - Simplified from Wikipedia

If you are an old person (i.e. your birth year starts with 19), you may remember hearing about this minor catastrophe:
On 12 November 2001, about 6,600 of the photomultiplier tubes imploded in a chain reaction, as the shock wave from the concussion of each imploding tube cracked its neighbours. The detector was partially restored from April to October 2002 by redistributing the photomultiplier tubes which did not implode, and by adding protective acrylic shells that are hoped will prevent another chain reaction from recurring (Super-Kamiokande-II). - Wikipedia
Looking for pictures of the catastrophe, I found this excellent video:

More Whole Earth
 |
| Whole Earth Catalog |
The Whole Earth gang has indexed all of the Whole Earth publications, so now you can search the catalogs and other stuff.
The (Searchable) Whole Earth
Based on the (incredible) archiving effort of the Whole Earth Index to scan and digitize all of these old issues, by Gray Area and Internet Archive. That effort was led by Barry Threw, designed by Jon Gacnik and Mindy Seu. More info here. This site (+ OCR-ing these pages, embeddings, search functionality, and this webapp) was built by Lucas Gelfond, you can read the source here.
