LCM and HCF algorithms

/*work out the Highest Common Factor, i.e the largest number that can
fit into the two numbers
and the lowest common multiple
i.e the smallest whole number which is a multiple of the two numbers
i.e 12 and 15

/*the two numbers I'm working out LCM and HCF for */

Great Writing Conference

Took part in the Great Writing Conference this weekend at Imperial College, heard some interesting papers and presented my own garbled version of a paper, but left wondering what the point of it was.

Dreamt I was in a crashing plane

The last few weeks I've been discussing lucid dreaming with a number of different people, several of whom have said you should try to read a book or look at your hands to see if you can recogonise patterns etc while dreaming, since those conversations I've had two more lucid dreams in which I've remembered to find something to read and to look at my hands, then turn them over and try to remember the lines on them. Last night I dreamt I was in a plane that was crashing, as it was about to hit a bridge I thought, 'this is really going to hurt' then I realised it was a dream and said to myself 'it cant hurt' and just went straight through the concrete and out the other side. I looked at my hands to remember the patterns on them, I'd done that before, but they were blue, this time they were my normal hands and I could remember the patterns, I found a boy reading a book and I looked at the title, it was a book on Coffee...I woke up and it was morning...the most lucid dream I've had so far.

Derek Jarman's Wittgenstein

http://www.youtube.com/watch?v=6WzqyO-wIMI
Found Derek Jarman's Wittgenstein on the web, I'm framing the Buddha box/Zen garden as an investigation into the limits of symbolic logic, carefully (and slowly!) reading the The Tractatus Logico-Philosophicus ("Logical-Philosophical Treatise"). Section 4 is the tricky one:

4.1 Propositions represent the existence and non-existence of states of affairs.
4.11 The totality of true propositions is the whole of natural science (or the whole corpus of the natural sciences).
4.111 Philosophy is not one of the natural sciences. (The word "philosophy" must mean something whose place is above or below the natural sciences, not beside them.)
4.112 Philosophy aims at the logical clarification of thoughts. Philosophy is not a body of doctrine but an activity. A philosophical work consists essentially of elucidations. Philosophy does not result in "philosophical propositions", but rather in the clarification of propositions. Without philosophy thoughts are, as it were, cloudy and indistinct: its task is to make them clear and to give them sharp boundaries.
4.113 Philosophy sets limits to the much disputed sphere of natural science.
4.114 It must set limits to what can be thought; and, in doing so, to what cannot be thought. It must set limits to what cannot be thought by working outwards through what can be thought.
4.115 It will signify what cannot be said, by presenting clearly what can be said.

With the Buddha Box you can never see directly in it, only via a camera, and then only when Brainwave states are those synonymous with 'higher consciousness'.
