"Give me the title of one of the books and I'll try to have a look."

I recall encountering it in a tech manual for a Studer A 727 CD player. Professional model we used in radio stations back in the early '90s as a comprehensive introduction as to how the damned things worked.

Yep. Go to page 11. The way the wrote this, the MSB is on the right.

I really don't know, but I have a hypothesis (apart from constraints perhaps arising from the fact that the data is transmitted).

When the AUX nibble is used for carrying extended audio data, it presumably contains the least significative bits (or the CD would be unplayable on machines using only the AUDIO SAMPLE part). So placing the LSB on the left, near AUX, allows to grab bits 4 – 27 in one swoop (if AUX too goes from LSB to MSB from left to right, which is the case).

Whaddya think, pure fiction? :P

Mushroom trivia:
Fascinating facts about fungi
  • "Fungi are in a kingdom of their own but are closer to animals than plants
  • They have chemicals in their cell walls shared with lobsters and crabs
  • A fungus has been discovered capable of breaking down plastics in weeks rather than years
  • There is evidence to suggest that yeasts - a type of fungus - were being used to produce the alcoholic drink mead as long ago as 9,000 years ago
  • At least 350 species are consumed as foods including truffles, which can sell for thousands of dollars apiece, quorn, and those in marmite and cheese
  • Plastic car parts, synthetic rubber and lego are made using itaconic acid derived from a fungus
  • 216 species of fungi are thought to be hallucinogenic
  • Fungi are being used to turn crop waste into bioethanol
  • Products made from fungi can be used as replacements for polystyrene foam, leather and building materials
  • DNA studies show that there are thousands of different fungi in a single sample of soil, many of which are unknown and hidden - so-called "dark taxa"

Cosmic ray transmission muography of a full/empty water tower

Muons are negatively-charged particles similar to electrons but about 207 times heavier. Random cosmic/cosmic-ray-plus-atmosphere-generated muons naturally bombard the Earth all the time and they can penetrate hundreds, up to thousands of meters of solid rock.

Considering the penetrative power of muons, this is a rather "easy" application: a concrete water tower with and without water, after 4-day exposures using a small (0.25 m2) sensor downstream of the tower. Other ways of imaging use multiple sensors on both front/back of the object, or all on one side, or can measure deviation of muons instead of absorption.
Same technique used on the Pyramids. :wink:
