New Novel: ‘Conscious’ by Vic Grout

What makes something sentient?  What does it take for an entity to be aware of its own existence and to want to interact with the world of its own accord?  Is it a gift from God or hard science?  Is it something fundamentally human or animal in nature or is it a simple technological principle based on brain size?  There are many models, of course.  But, if consciousness is simply a natural product of neural complexity then eventually, in theory, we might build something – a computer or a machine – that was actually big enough to wake up!

Oh, wait …!

The widespread ramblings, which have appeared on this blog over the years, now make a partial contribution to a novel: http://tinyurl.com/VicGroutConscious

Vic Grout’s Conscious is set a year or three into the future.  The ‘Internet of Everything’ is making the world a more connected place than ever before.  People’s lives are becoming increasingly automated.  But something odd is happening … ‘Things’ are beginning to misbehave and no-one can work out why.  What starts as an amusing inconvenience quickly becomes very serious indeed!

A ragged bunch of academics, scientists and philosophers are on the case – and may know the answer.  But now they have to convince people that their crazy explanation is true.  And that’s only the start.  Against a backdrop of a world suddenly beginning to fall apart, they’re in a race against time to get someone to do anything about it.  And not everyone is on their side!

Mathematicians and Computer Scientists

It’s the holiday time of year: so a slightly lazy post for August.  Adapted from a letter published in this month’s edition of Mathematics Today

For anyone who’s worked in the ‘Twilight Zone’ between mathematics and computer science for any time, June’s Mathematics Today article, Urban Maths: A Roundabout Journey [on rounding issues in computer calculations], would have struck a distinct chord.  They will have often come across situations in which mathematicians and computer scientists don’t quite see eye to eye.  The following, fairly well-known, combinatorial exercise is another good example.

How many ordered ways are there of summing contributions of 1 and 2 to a given integer, n?  So, for example, 1+1+2+1+1 and 2+2+2 are two of the 13 different ways of making 6.  Call this number f(n) so that, in this example, f(6) = 13.

The standard combinatorial approach is to consider the first term.  The only two options, 1 (leaving n-1 to make) and 2 (leaving n-2) lead readily to the recurrence relation f(n) = f(n-1) + f(n-2).  Easy enough, yes, but the interesting question now is what to do with it?

Santa in the Continuum

This year’s festive offering considers countable and non-countable infinities and follows (very) loosely from last year’s discussion of deterministic and non-determininstic optimisation

[Specially for Alex Irvine, who is either having trouble getting his head around infinite sets or still believes in Santa Claus: we’re not allowed to say which]

Father Christmas has a problem. The Intergalactic Department of Work and Pensions (IDWP) has threatened to cut his tax credits because he apparently only works one day a year. He’s tried to point out that he’s the head of a vast multinational organisation of elves and reindeer, who themselves work all year round, but that doesn’t wash with the IDWP boss, Ian ‘Dunkin’ Smiff, because his dad didn’t go to public school.

Planets

So, he’s been given extra work to do: a lot of extra work to do …

Drop the Dead Donkey! (Is that really ‘News’?)

Most of us, watching TV from time-to-time, find ourselves saying, “Why’s that made the news? Surely there are more important stories?”  That may well be true so is there a logical way to approach the issue?

Let’s start with a couple of extreme examples, to try to get a feel for this:

  • On May 7th this year, the UK went to the polls to elect a new government.  Just about every news programme on radio and TV, as well as the whole Press, led with variants on the ‘story’ “Voters start voting in the General Election”.  But was this actually ‘news’?
  • At the other end of the scale, what about the dog that can play the piano? (Or any similar ‘and finally’ space-filler.) Is it worth the space?
