Re: How Do Math Magicians Know Your Number? | Quanta Magazine

Puzzle 3
To begin the process of exclusion, we have two primary clues: the product of the values must be less than 100 (by the sum of 50+50), and the product of the values must have 3 or more integer factors (other than 1 and the value) since S could not deduce the values. So, the first cut is to select composite numbers that meet these criteria. In my limited test, in the range of product values of 4 to 56, there are 17 combinations of interest.

Once P hears this, the slip he is holding has only 1 product value having two of its three factors making the sum he knows.

P=10, S=16, factors 2 and 8. In the selected set, 16 is unique in that it has exactly 3 factors.

I believe the "11th decimal place" accuracy in the article refers to the calculated alpha value of 0.0072973525628(6), not the inverse. Didn't understand your reference to "1812.04130", should this be
137.035999046(27), at 200 parts per trillion, from the Müller paper?

Professor Schwarzschild's death at 42 was due to a rare autoimmune disease genetically linked with Ashkenazim ancestry, not from any military action, per a 2008 biography.

Treasure One
With a complex plane parallel with the island surface, the two trees on the real axis at points -k for the Oak and +p for the Pine, and the origin equidistant between the two trees, the treasure will be at (3p)i.

Thanks; yes. With smaller LED matrix displays, it's obscured by the inherent technical limits of contrast and viewing angle.

I'm sure the title of this post is not intended to solicit, say, links to interesting architecture in Singapore or schematics for home-built guillotines, but it seems to be the only handy entry point for communication which may be of interest to Datachondrians that is not exactly associated with existing topics, to wit: Algorithm-based data mining used to create specific content based on revenue potential.

Obviously not at all a new concept, but accomplishing a new system and production-line process to monetize data seems relevant, especially when the scale is "everything in the world."

Interesting. Have you purchased anything in the DAISY format, which appears to do this type of synchronizing? Also see: http://www.niso.org/workroo... which has an extensive (sleep inducing) description of standardization and format for audio/data.
Also: http://www.readhowyouwant.c..., which may be a source to produce books in this format.

Don't know if this is of any interest. http://www.toccon.com/toc20...
