18-02-2004 12:02PM#1A Nightwatch man on duty one particular night in a
very large warehouse had a dream that his
boss would be killed in a train crash the following evening going
home from work -
The next morning when the nightwatch man was nearly
finished his shift - his boss arrived in work.
The nightwatch man informed him of his dream the previous night,
and warned his boss not to get on the train after work.
That evening the boss took the bus,
while having his dinner that evening, there was a newsflash -
the 6.00 train had crashed killing every passenger on the train -
following morning the boss arrives at work - walks up to the
nightwatch man and fires him ............ WHY -
emmmm

OK, what about this (retarded) one -
There is a big pond.
On day 1, 1 leaf is dropped on the pond.
On day 2, 2 leaves are dropped into the pond.
On day 3, 4 leaves are dropped into the pond.
On day 4, 8 leaves are dropped into the pond.
On day 5, 16 leaves are dropped into the pond.
On day 6, 32 leaves are dropped into the pond.
...
The pond is full on the 100th day.
When was it half full?
You better get it straight away mongo!

Day 1: 1 leaf falls, and there is 1 leaf in the pond.
Day 2: 2 leaves fall and there are now 2+1 = 3 leaves in the pond
Day 3: 4 leaves fall and there are now 4+2+1 = 7 leaves in the pond
Day 4....
Do you see? Now I don't have a program handy but can anyway calculate how many leaves are on the 99th and 100th days respectively and see if these figures work? It's a geometric series, if I recall correctly and - as it happens - this makes the riddle tricky :dunno:0 -

Ignore the 100 days (the same principles apply), imagine there are only 10 days, at day nine the pond is nearly half (511/1023) full of leaves.Day Today Total 1 1 1 2 2 3 3 4 7 4 8 15 5 16 31 6 32 63 7 64 127 8 128 255 9 256 511 10 512 1023
