Saw a bit on the local NEWS about this :) HOA tells the guy that he can't have his boat visible from the street. "OK", he says. "I'll put up a gate."

Visited there once several years ago. Lot of cool vintage stuff in the museum. I was fascinated by the circus-in-miniature...everything's there, down to the smallest detail. And no two of the hundreds of 4" figures are alike.

Chrysler 1964-65 doomsday device, a DOHC 426 hemi. Never produced, never run under it's own power. As soon as NASCAR heard about it, all overhead cam V8's were banned in 1966. After the ban, this engine was no longer needed.

Progress being made on righting the hulk of USS Oklahoma (BB-37). March 18th, 1943, was ten days after the pull began and you can mark the progress by the water rings on her deck. According to the caption she's at 109 degrees (zero being the goal).

Deutz F4L912 Aircooled Diesel Engine.
52-72Hp
100mm Bore, 120mm Stroke
The "Deutzer Motorenwerke" (named after the part of Cologne where the Factory is/was) were founded by no one else than Nikolaus August Otto himself in 1864 which makes it the oldest Engine manufacturer in the world.

Sigourney Weaver: "I once had a fire in my apartment [after the movie], and the firemen came to put it out. One of them opened up my refrigerator and said, 'Whoa, you better call the Ghostbusters.'"
Julia Roberts auditioned for the role of Dana Barrett in "Ghostbusters" (1984), but it was Weaver who attracted the filmmakers' attention. There was some resistance to casting her because of the generally serious roles she played in "Alien" (1979) and "The Year of Living Dangerously" (1982). Weaver revealed her comedic background, developed at the Yale School of Drama, and began walking on all fours and howling like a dog.
It was Weaver's suggestion that Dana become possessed by the demonic dog, Zuul. Reitman said this solved issues with the last act by giving the characters personal stakes in the events. Weaver said kids would come up and ask her if she really turned into a dog.
Weaver also changed the role from that of a model to a musician, saying she can be kind of strict, but "you know she has a soul because she plays the cello."
Weaver floating is an actual physical effect. The actress was put in a full body cast and attached to a post hidden in the curtains. According to the DVD commentary, the effect came from Ivan Reitman's Broadway experience.

BRLESC I (Ballistic Research Laboratories Electronic Scientific Computer¹) (1962)
Army Research Laboratory mathematician/programmer Norma Stec and her assistant Lou Moeller are monitoring a satellite tracking calculation on the console of a massive high-speed 68-bit digital computer, a $3 million machine built by the US Army's Ballistic Research Laboratory at Aberdeen Proving Ground with assistance from the National Bureau of Standards and designed to take over the computational workload of EDVAC² and ORDVAC³, which themselves were successors of ENIAC⁴. The 35 kW machine was capable of five million (bitwise) operations per second. Fixed-point additions taking 5 µs, floating-point additions took 5 to 10 µs, multiplication took 25 µs, and division took 65 µs. The applications of BRLESC included exterior ballistics⁵ and problems such as high altitude, solar and lunar trajectories, computation for the preparation of firing tables and guidance control data for Ordnance weapons, including free flight and guided missiles as well as ballistic measurement problems, including photogrammetric, ionospheric, and damping of satellite spin calculations, reduction of satellite Doppler tracking data, and computation of satellite orbital elements⁶. The arithmetic unit alone contained 1,727 vacuum tubes of 4 types, 853 transistors of 3 types, 46,500 diodes of 2 types, and 1,600 pulse transformers. Logical events are controlled by a five-phase megacycle clock, permitting decisions at the rate of 5 MHz. The storage system of the machine consists of a high-speed magnetic ferrite core memory of 4,096 words. Each word is 72 bits long, which is equivalent computationally to approximately 19 decimal digits, since 4 parity bits and 4 sign bits are not included in the operands. The complete read-write cycle time of this memory is 1.5 µs.

The applications of BRLESC were as follows:
1. Exterior ballistics problems such as high altitude, solar and lunar trajectories, computation for the preparation of firing tables and guidance control data for Ordnance weapons, including free flight and guided missiles.
2. Interior ballistic problems, including projectile, propellant, and launcher behaviour, e.g., physical characteristics of solid propellants, equilibrium composition, and thermodynamic properties of rocket propellants, computation of detonation waves for reflected shock waves, vibration of gun barrels and the flow of fluids in porous media.
3. Terminal ballistic problems, including nuclear, fragmentation, and penetration effects in such areas as explosion kinetics, shaped charge behaviour, ignition, and heat transfer.
4. Ballistic measurement problems, including photogrammetric, ionospheric, and damping of satellite spin calculations, reduction of satellite doppler tracking data, and computation of satellite orbital elements.
5. Weapon systems evaluation problems, including antiaircraft and antimissile evaluation, war game problems, linear programming for solution of Army logistical problems, probabilities of mine detonations, and lethal area and kill probabilities of mine detonations, and lethal area and kill probability studies of missiles.
