A series of Scientific Coolnesses

A few weeks back I read about a number of very cool things from the world of science, however it has taken me a little while to get around to writing about them.

Without further ado here they are:

There. Wasn’t that both varied and fascinating.

They don’t build ’em like they used to

In an amusing story out earlier this week, it turns out that one of the NASA’s Mars Rovers has finally broken (somewhat).

The rovers, each designed to last 6 months, have been going for 2 years, and are still happily trunding around their landing sites doing really good science. The other day however one of the rovers broke a wheel. 1 of the 6 it has. And so with one wheel trailing it’s just continuing to roll around on it’s remaining 5 wheels. Now that’s what I call solid.

Strugling against the machines

We have recently started using a new computer system at work, which allows (to a limited extent) electronic record keeping and note taking for patient charts.

Old chart entries are scanned in, so that you can pull up old charts from any computer in the hospital, and things like xray reports and blood test results are all accessible through it.

I personally find this a godsend, as it allows me to do a fair bit of my work without writing, and from anywhere I want to do it, rather than being tediously paper based from wherever the charts are kept (on the ward, in medical records, etc).

Recently however they added a new feature which allows you to directly add notes into the online charts, with the idea that in certain situations (especially outpatient clinics) doctors would simply type in notes, rather than writing things and having them scanned later.

Brilliant, I thought, and promptly started entering notes left right and centre, and taking to it like I’m sure the IT people were hoping everyone would, however I have been quite bewildered by the fierce resistance I have seen in my fellow doctors to the system.

Even the relatively tech literate and young (comparatively speaking) doctors seem to resist using it, not because they can’t, but seemingly because they don’t want to, and it is new technology. They want to keep on writing illegibly. They want to sort through piles of crusty old paper charts. They like being able to winge about the system, even though it really is quite a good piece of software, and both an improvement on the previous version that was in use last year, and a monumental improvement (in my opinion at least) on the paper systems of old.

I suppose that that is just the way the world works. Some day it will be me being tech illiterate, and some other young upstart winging at my intransigence.

Water and power from poo

Straight from the “How we should really be using our brains” files, comes this story about the guy who built the segway (if you have no idea what that is, have a look at the site: they are an astounding piece of engineering, but are equally a spectacularly frivolous toy in almost all applications) who has designed a 1kilowatt power plant and a ~1000L/day water purifier system that work by burning cow dung (or for that matter, just about anything you can find that you can set fire to…).

The notion is that if they can get the price of production down, and put one or two in each small african and asian village, then the villagers will have clean water (which in effect = no water borne illness, which = decreased illness, increased productivity, and better lives) and power for small applications (like a community refrigerator, or a light bulb in each house (which will allow them to spend evenings in recreation, education, or further productivity)).

For all the brilliance and creativity of our modern science and engineering, there are far too few of these ideas being developed as far as I can tell, and so we must loudly aplaud this guy for his genius and his social responsibility.

Celebrity confusion

It was very funny flicking past Oprah the other day long enough to watch her being utterly confused by the concepts of how the internet worked.

The guy who was explaining, who was using really basic terminology and analogies to explain the system, would explain how routers and network switches and DNS servers worked and Oprah’s brow just furrowed deeper and deeper. She seemed to kind of think that it all just went through the air, and had no idea how things (emails for example) found their way from their starting point to their intended destination.

Very funny to watch. Also very scarey when you consider that Oprah is apparently a pretty intelligent individual. Obviously not that tech savvy though..

Sticking it to China

Being someone who hasn’t let the fact that china has the world’s fastest growing economy distract me from the fact that it also has one of the most repressive systems of goverment*, I am mighty pleased to see this article in slashdot, which talks about a new piece of software which passes encrpyted packets to allow people in china (and other countries that monitor internet activity of individuals who want to read about such subversive ideas as “freedom” and “democracy”) to read pages that would otherwise be blocked by government firewalls, and to read them in a way that is theoretically undetectable.

Here’s hoping it works, and that it inspires others to release other pieces of subversive software to encourage freedom of information.

*which of course sets me apart from numerous other people, companies, organisations and governments who seem happy to turn a blind eye if there is a profit or advantage in it for them (microsoft, google, US government, we’re looking at you…).

Predictable

Turns out that mobile phones can predict your behavior. Well not the phones themselves, but a computer program tracking where your phone goes, when you go certain places, and who you regularly come into proximity with.

After tracking you for a while it can pick up patterns of movement and socialisation, and can begin to (eventually quite accurately) predict your future movements etc on the basis of your historical actions.

I wonder how long it will take for the intelligence community to start doing it….

Fun at the fixit shop

I found this little gem the other day, a site containing photos of some of the very very wrong things people did to their computers in order that they might need a trip to the repair shop. Sometimes the technical ability of the general population in wrecking their own computers can be truely astounding.

Delamination

I remember in the early days of writable CDs, and all the doom mongers in the computer magazines going on about how writable CDs would be an unstable and unreliable form of data storage, and that they would crack and warp and loose data and… well the list went on ad nauesum.

Well at the time, and in the intervening years, I maintained my skepticism on the issue, having never really had any data loss or CD problems that could be attributed to anything other than user stupidity (I’ve had several CDs scratched to the point of unusability, lost several, and accidentally thrown a couple out). This changed today however, when I opened one of my CD wallets and found that one of the CDs which I hadn’t looked at in probably a year, had essentially delaminated. It was really weird. The top level had basically lifted off the disk.

Doesn’t really matter though, as the stuff on the CD was just an old backup, but it was still interesting to see this theory in practice.
