An Incomplete World

Posted in computers, Science, Uncategorized with tags on December 9, 2015 by davidnm2009

I burnt out badly on science blogging several years ago, so I don’t do much of it now. But, this result is interesting, so I’m bending said rule a bit here:

Basically the researchers have identified an applied physics problem, related to the structure of matter, that may actually be insoluble due to Godel’s incompleteness theorem.

What’s interesting about this is a) it feels weird (here’s something that happens in our universe that can’t be analytically-modeled) and b) by implication, we finally have a viable refutation for Simulation Theory. If parts of our basic physics can’t be analytically modelled, then also, we can’t be a ghost-world running on someone’s computer. Because said computer literally wouldn’t be able to perform the required maths, no matter how powerful its components.

(Also, apparently my blog doesn’t already have a category for “physics”? Bwuh … ? How did that happen?)

Misadventures in (Re-)Building Computers

Posted in computers with tags , , on June 8, 2013 by davidnm2009

I’ve had an interesting few weeks.

On the 23rd of May, my venerable old desktop PC (Canidae) died a final death. When the end came it was abrupt; I was right in the middle of a Mass Effect multiplayer match when Canidae departed from this world! The screen went dark, the power light vanished and silence descended inside the room. My first thought was that I’d been kicked off again by EA’s notoriously-wobbly servers – but no, no such luck!

As these things tend to, Canidae had picked the worst possible time to expire. I’m currently job-hunting (that being the polite way of admitting to unemployment!) and also trying to get on with the corrections to my PhD thesis. Having my home computer expire on me at this juncture … yes. Not an ideal event, needless to say!

Further investigation eventually revealed that the culprit was a fried motherboard.

Rotten Apple

Posted in computers, Personal with tags , , on August 16, 2010 by davidnm2009

I used to like Apple. I actually have an ancient, 2001-vintage iBook. Every now and then, I even turn it on, if only just to see how much more the hard drive has died since the last time I played with it. (In a way it’s quite sad – I have some good memories from that computer!)

Unfortunately, Apple seem to have taken a turn for the worse over the last few years.

In 2006, I re-joined the modern world of computing with my new laptop. This was the first computer I’d bought in several years. It was wonderful, for about a fortnight. Then I installed iTunes.
