Zach:

Condolences on the loss of your friend.

For the rest, Schroedinger's Killer App is available online in PDF form here.

I'll probably buy the hardcopy, too, since I prefer something that I can read in bed and since I spend all day in front of a screen, I'd rather look at something other than glowing phosphors before I go to sleep at night.

I found the free PDF, but I didn't download it yet. Wanted to know if it was legal first. (If I'm gonna go to hell, it's going to be for something better than bootlegging a book I could afford. :lol: )

I have to assume that it's free and legal -- CRC Press/Taylor & Francis is pretty stringent about copyright violations. And it's on the late author's own site.

Anyhow, I've ordered the book from CRC Press so my soul is safe.

Did he really attribute the Mathematical Classic to Sun Tzu?

It was written by Zhang Qiujian and was compiled in the fifth century.

No actually it was fine there are two "the Mathematical Classic"s'

One actually by Sun Tzu 3rd-5th century : https://en.wikipedia.org/wiki/Sunzi_Suanjing (Sunzi Suanjing is the same person as Sun Tzu apparently)

One by Zhang Qiujian Suanjing:
https://en.wikipedia.org/wiki/Zhang_Qiujian_Suanjing

Props for knowing about it though. I'm Chinese and I didn't know xD im sorry

^ My mistake, reading more closely Sunzi Suanjing is not the same person as Sun Tzu he was just named after Sun Tzu.

So then you have Sun Tzu, who wrote "The Art of War"

Sunzi Suanjing who wrote "The mathematical classic" and was apparently named after Sun Tzu, because in chinese Sun Tzu is spelled as Sunzi: https://en.wikipedia.org/wiki/The_Art_of_War

and Zhang Qiujian Suanjing who also wrote a book called "The mathematical classic".

Ain't been the tradition ascribing novations to staid figures? E'en now, such misfacts.

I just got my copy of Dowling's book Schroedinger's Killer App and I can see why Zach liked it.

I'm just about through the first chapter (and admit that I don't get the whole "verifiable quantum entangled clocks" model entirely but that's a subject for another forum, I suspect).

If I had a criticism, it would have to be "too many notes" -- endnotes, that is.

A lot of books have endnotes, of course, usually just bibliographic references which the casual reader can largely ignore. Dowling, however, interpolates all sorts of wisecracks, digressions, and little stories (including one about getting stared down by Paul Dirac in a public lecture) that actually are interesting.

I wish that he or his editor had separated the bibligraphic reference from the digressions by using actual on-page footnotes for the digressions while reserving the endnotes for the others. I find I have to flip back and forth between the main text and the end notes constantly and actually have to have two bookmarks so I don't lose my place.

I'm not sure whether the PDF would be any easier to deal with. I suppose it might depend on the PDF reader involved. In my copy of the PDF, the notes aren't hyperlinked, so you'd have to scroll backwards and forwards.

Anyhow, other than that quibble, highly recommended. I have no idea whether I'm smart enough to end up with any new understanding of quantum mechanics (the "Two Beers" model is not applicable, since I stopped drinking beer a while ago).

I found and downloaded the PDF from Dowling on the Killer App. I am a computer nerd and have been one since my Junior Year in High School (1963). Dowling mentions that the NSA has been a classified agency until the 1990's. In college, (Drexel), I and several of my classmates were interviewed for a co-op job at the NSA and we were never told to keep its existence secret. I was not offered the job, but I've told this story several times. Many times, the person I've told the story to has acknowledged that they knew of the existence of the NSA, so I wonder where Dowling got his information.
Sorry that your friend passed away so young.
(And, yes, I am able to understand enough of it to get by.)

The NSA's existence was originally classified but that was way back in the Truman Administration and not officially acknowledged until the 1970s. It was, however, a fairly open secret and often jokingly referred to as "No Such Agency."

The Church Committee in the mid-1970s certainly openly discussed its existence by name.

In a previous gig, I personally installed some software I'd developed on one of the NSA's IBM mainframe computers in the early 1980s -- I'd say around 1983 or 1984 -- and I was not sworn to secrecy (I did my work on a non-classified system and there were no secrets involved other than how really horrible the software was). I did not carry a NSA clearance so saw or heard nothing of particular interest and I did require a 'baby sitter' with me at all times.[1]

At another gig, I had a colleague who was a former NSA mathematician and, again, there was nothing secret about that, though I could always get him into a bit of a dither if I started asking him questions about number theory.

For a number of years NSA people didn't acknowledge their employer.

You could, however, always tell the NSA attendees at conferences because instead of a university or company affiliation, their badge would just say "US Government." I think CIA were more open (though I won't swear to it)>

I seem to recall seeing a few of those badges at conferences in the early to mid-1980s but that's a bit hazy.

I'm not certain when that policy changed, but that might be the source of Dowling's confusion.

[1] A Dowling-like digression: I also consulted on a nonclassified project at Lawrence Livermore Labs and not only was I escorted everywhere, including the restroom, but when I was in the restroom, they would put a little sawhorse in the doorway warning that an uncleared person was inside. Similarly, at the NSA, as I was escorted through the building, along the way, my escort would flip a light switch which would start a rotating flashing yellow light mounted to the ceiling warning of the presence of a non-crypto-cleared person. All very bizarre and entertaining, in a "spooky" sort of way.

I think the ideal method of presentation might be notes as hovertext. It would be slightly more challenging to implement in a physical book, however.
