Missile Guidance Systems Explained
2006, February 23, Thursday, 14:24
Here's a wav file explaining missile guidance, allegedly from a genuine training tape: AF Guidance

According to Missile Guidance for Dummies, this is transcribed from an Air Force training video on the topic of missile guidance.

Jim Kirkpatrick's website further states that this is attributed to the Ground Launched Cruise Missile (GLCM) in the Dec 97 publication of Association of Air Force Missileers. In this newsletter, a similar text on the GLCM Guidance System was "submitted by Colonel (Ret) George Grill, who was with General Dynamics at Greenham Common AB, England - it may not be the first time you have seen this - is seems to apply to all guidance systems."

Incidentally, it was very cold. It was 35 degrees F with 13 mph winds.

Godel's Theorem
2005, November 21, Monday, 20:38
Nothing really original here. Just a link to a webpage which tries to put it succinctly. I spent numerous hours with the $7 copy of Godel's "On Formally Undecidable Propositions"

See this terse description of Godel's Incompleteness Theorem

While I liked Godel, Escher, Bach: An Eternal Golden Braid by Douglas Hofstader (I first read Radha's copy in the basement of my dorm at CWRU while doing bunch of laundry), it's been criticized for twisting each of the three components a bit too much to fit together.

A few years ago I worked through GEB again while not distracted by laundry. It clicked better now than it did in 1993 (over ten years ago).

So I took pen and paper and worked through the first quarter of Godel's paper itself before I got bogged down in the damn notation. For example, I think I couldn't keep in my head that Bew(x) came from the German word Beweisbar and meant "provable". I started to write in the english translations but had to stop. I need to tackle this again. Why? I'm not sure. I'm hoping that the
modernized translation will make things more accessible.

Occasionally I attempt to work through Godel and other mathematical logic papers to occupy my brain to the extent that it tends to to blank out pretty much any other through process going on.

On somewhat of a tangent, I kept a New Scientist magazine article which I quite liked which is entitled In the beginning was the bit. It paraphrased/described a paper by Professor Anton Zeilinger called
"A Foundational Principle for Quantum Mechanics" We've since lapsed in our subscription as New Scientist has gone a bit down hill lately. It's a shame Scientific American has been dumbed down. I appreciated not being able to fully appreciate every article.
