A friend of mine was a weapons office on a USN sub, one day we were talking
about terrorists making a bomb. He started by saying the technology is
above their heads. My response was get a bucket and put enough fissionable
material in it and boom.
Sorry but that won't work. After the first couple of generations of the
chain reaction it simply blows itself apart and the chain reaction dies.
That's why A bombs have POWERFUL chemical explosives to FORCE the nuclear
material together. Getting the bomb to stay together long enough to work
(ie, use up most of the available nuclear material) was probably THE
biggest problem in the building of the A bomb. Ultimately two approaches
were used, one was to fire to hemispheres of nuclear materail together by
means of a modified 16 inch navel gun (Tall-boy) and the other was to
implode a hollow sphere of material by explosives that completely
surrounded it (Fat-man). Go read 'Building of the Atomic Bomb" by Richard
Rhodes. It has a lot of detail on the subject. That book and "Building of
the Nuclear Bomb" are both very interesting reading.

of it goes overseas. Supposedly this is coming
from the Department of
Homeland Security and has something to do with 9/11. (Have you noticed
that
every new, rediculous requirement is in response to 9/11?) This is a
When the terrible events of 9/11 occured, one of my first comments was 'I
fear the reaction of the governments more than I fear the terrorists'.
Govenments have a habit of over-reacting, particularly if it means they
can impose more restrictions on the public...
Over here, you can be arrested for 'possessing information of use to a
terrorist'. Let's looks along my bookshelves...
The 555 timer data sheet
Data sheets on various other timing chips
Electronic magazines with timing circuits in them
Various books on mechanical and electronic clocks (clocks have long since
been an interst of mine)
Books on chemistry
Books on nuclear and particle physics (not suprising as I did a Ph.D. i
the latter)
Books on metalworking
A London street map
A London underground railway map
Care to explain why those are not of use to terrorists. For that matter a
cookery book is of use to a terrorist (presumably they have to eat
sometime...)

He said it wouldn't be efficient and you wouldn't no when it would blow, I
said who cares if you have a nuclear explosion in a major city that's
terrorism.
