Thought for the month

“You cannot have freedom without a rule of law ... and if you don't have it, what you tend to get is corruption and that is death to freedom, it's death to truth, it's death to honour, it's death to democracy.”

Margaret Thatcher, 1 October 1996.

Quicker to walk

If we cannot have a food replicator, how about teleportation? Sadly a group of MPhys students at the University of Leicester have severe doubts about the viability of this transportation method. They note that every human that is teleported will need to be represented in transferable data. This would be a mix of physical DNA and genomic data coupled with the information contained in the travellers brain. The students estimate the total information content to be around 2.6 x 1042 bits. Using a teleportation bandwidth of 29.5 to 30 GHz, the students calculated that the data transfer would require up to 4.85 x 1015 years. The universe is thought to only be around 14 billion years old.
