Re: Encode a message so it can't be read until a certain time?

As long a the machine is not compromised, should be just fine. I think the presumption is that the stakes are high enough that the machine will be attacked by very smart people. It's running Outlook. It's a dead duck. Jose Assuming it can be found. This could be a running on a virtual machine anywh...

Re: How do satellites not crash into each other?

Bear in mind, that in this context, a bullet is a large, slow moving object. The more common type of debris would be a fleck of paint, moving at ten times the speed of a bullet.

Trickier problem than it seems. (goat in a circular paddock)

You have a goat, tied to the fence of a circular paddock. The paddock has a radius of 100M. You want the goat to eat HALF of the grass.

How long does the rope need to be?

Assume an even covering of grass, and don't worry about the goat's neck length etc.

Re: How do satellites not crash into each other?

Occasionally they do! It is actually going to be quite a big problem soon. A lot of satellites are in geostationary orbit, this means a set distance from Earth. The probability of a satellite hitting another is very low, HOWEVER, a particle the size of a grain of sand can easily smash a satellite in...

Re: Encode a message so it can't be read until a certain time?

Most email clients can do this. Just set up a PC (real or virtual) somewhere, load Outlook, configure the email and send away! (Options, more options, Do not deliver before) on Outlook 2010.

As long a the machine is not compromised, should be just fine.

Re: energy currency?

A few sci-fi movies and books have used the theme of life being a form or currency. "In Time" spring to mind.

Re: Trolley Problem

Imagine you are a doctor. You have a ward full of terminal patients, and spend one day a week running a clinic. I guy from out of town comes into your clinic for a medical check, as part of getting a pilots licence. You examine him, and find no signs of poor health. Not only is he healthy, but he ha...
