bjaspan (Barr3y Jaspan):
It's amazing that after years of complaining that no one does "real"
AI research any more and having people tell me that I don't know what
I'm talking about, I've finally discovered that someone else (with
much more clout than I!) agrees.
"It is instructive to reflect on the way in which earth-based
biological evolution spent its time. Single-cell entities arose out
of the primordial soup roughly 3.5 billion years ago. A billion years
passed before phtosynthetic plants appeared. After almost another
billion and a half years, around 550 million years ago, the first fish
and vertebrates arrived, and then insects 450 million years ago. Then
things started moving fiast. Reptiles arrived 370 million years ago,
followed by dinosaurs at 330 and mammals at 250 million years ago.
The primates appeared 120 million years ago and the immediate
predecessors to the great apes a mere 18 million years ago. Man
arrived in roughly his present form 2.5 million years ago. He
invented agriculture a mere 19,000 years ago, writing less than 5000
years ago and 'expert' knowledge only over the last few hundred years.
"This suggest that problem solving behavior, language, expert
knowledge and application, and reason, are all pretty simple once the
essence of being and reacting are available..."
-- Prof. Rod Brooks, 1987

Well, first you get a near critical mass of U-235 or Pu-239. Mold this stuff
into a big ball. Now, surround the ball with beryllium. Wrap the whole thing
in a heart shaped batch of 5 mm/usec explosive with the sphere just touching
the apex of the heart. Slather a batch of 10 mm/usec explosive uniformly over
this assembly. Set a detonator at the base of the heart shaped device thus:
* *
* *
* *
* <==10mm/usec==> *
* * * * **********************************
* * * * * U-238 *
* * * * * ************************ *
* * * * * * * * * *
* * * * * * * * * *
|DETONATOR| <==5mm/usec==> U-235 * * * * Li6-D * *
* * * * * * * * * *
* * * * * * * * * *
* * * * * ************************ *
* * * * * U-238 *
* * * * **********************************
* <==10mm/usec==> *
* *
* *
* *
|<================first stage===========>| |<=======second stage===========>|
Set a second charge of Li6-D wrapped in a thick layer of U-238 next to the
device already constructed. When the detonator is set off there will be a
short sequence of events whereby the U-235 (or Pu-238) is compressed to a
prompt supercritical state, mucho neutrons will escape from the first stage
and bathe the second stage in a high neutron flux. The Li6-D will convert
to T-D at high pressure and temperature. The U-238 will fast fission. If
you use enough U-238 the T-D will be almost completely burned in a fusion
reaction before the device disassembles. It is a relatively simple matter
to model and optimize these parameters on modern desktop computer systems.
Depending on how much U-238 and Li6-D you put in this device you will get a
varying amount of visible light flash, thermal radiation, neutrons & blast.
In the words of the original designer -- this device is VERY VERY LOUD!!!
Unfortunately, some persistent toxic byproducts are produced by fission in
the U-235 and U-238 portions of this assembly. If you make the device too
big you may also: (1) strip the atmosphere off the planet, (2) ignite some
components of the atmosphere, or (3) generate undesired seismic activities.
You should probably keep a safe distance from the device when it explodes.
You may also need some special federal, state, and local permits to build,
maintain, transport, or operate one of these devices. The local branch of
the NRA should be a good place to go for initial advice on licensing.
