Comment Don't hurt the feelings of FSMs (Score 4, Insightful) 47

The summary (and TFA as well) seem to be committed to the following two points:

1. Finite state machines will be unrealistically simple when simulating emotional responses.
2. Behavioural-feedback is a necessary condition for realistic emotional displays.

Point number 1 is unwarranted. Finite state machines may elaborate their input at an arbitrarily high level of complexity -finite may still be very large. Part of such an elaboration, of course, may be inner transitions between states that effectively amount to behavioural-feedback. There is nothing intrinsically un-dynamic to FSM.

Comment Overgadgetting (Score 2, Insightful) 38

I love Wii; actually, I'm currently giving my life away to Super Mario Galaxy. But, having said that, I think this initiative is a clear case of overgadgetting. When playing Wii Fit, one already feels stupid when "jogging around Wii island" - that is, running on the spot with the Wii Controller in your pocket- but, making it part of a corporate health package? Come on. There must be some better use for that money. Better dental coverage, for instance, or whatever.

Comment Galileo, the moon-mapper (Score 5, Insightful) 60

Galileo discovered the law of inertia and formulated the equations of uniformly accelerated movement, helped improve the telescope and the microscope, described the orbits of Jupiter's satellites and, apparently, drew a map of the Moon.
On the other hand, Thomas Harriot drew a better, earlier map of the Moon.
In conclusion, and given that we know who Galileo is, it is a historical injustice that we don't know who Thomas Harriot is.

Somehow the conclusion does not seem to follow, does it.

The note only says that if you are familiar with Blue-ray rips found on BitTorrent sites you will instantly recognise Matroska + H.264. No "automatic equality" is involved in this (largely correct) claim, that I see.

And, yes, anyone familiar with BitTorrent will instantly recognise pirated software -some prefer to talk of software being shared, what with no pirates being involved in the activity.

I think you are right, and I made my point in a careless way. I stand corrected.

It is nevertheless still the case that scientists tend to think these days that computer simulations do explanatory work of the other kind. It is still an interesting question: do computer simulations provide evidence at all that some events in the real world have turned out one way or another?

Comment Explanation? (Score 4, Insightful) 98

There is something wrong but interesting about the idea that a computer simulation can explain what happened in a real-life incident. In the normal usage of "explain", only causally-related events can explain other events.

There is undoubtedly something to the contention that a computer simulation does some explanatory work, but it must be in a roundabout way. Maybe this: the computer simulation provides evidence to the effect that some prior event was able to cause the known outcome; but then it is the prior event (the bad choice of spin rate in this case) that explains the loss of the Beagle 2, not the computer simulation.

Simulations May Explain Loss of Beagle 2 Mars Probe 98

chrb writes "Researchers at Queensland University have used computer simulations to calculate that the loss of the US$80 million British Beagle 2 Mars probe was due to a bad choice of spin rate during atmospheric entry, resulting in the craft burning up within seconds. The chosen spin rate was calculated by using a bridging function to estimate the transitional forces between the upper and lower atmosphere, while the new research relies on simulation models. Beagle 2 team leader Professor Colin Pillinger has responded saying that the figures are far from conclusive, while another chief Beagle engineer has said 'We still think we got it right.'"

Comment Re:ALL Teachers are Paragons of Virtue (myth) (Score 1) 1589

Those myths are useful because teachesr, just like doctors, are way lower in public appreciation and social status than they should be.

Both these occupations I've just mentioned -and a bunch of others, to be sure- are fundamental for a society to get going, but somehow we have managed to hold in greater steem Procter and Gamble Brand Managers and (until recently, at least) Wall Street brokers.

Doctors prevent people from dying; teachers teach people how to read. Some praise of their jobs is simply a small step towards setting the record straight.

Gravity Lamp Grabs Green Prize 596

eldavojohn writes "A lamp powered by gravity has won the second prize at the Greener Gadgets Conference in NYC. From the article, "The light output will be 600-800 lumens — roughly equal to a 40-watt incandescent bulb over a period of four hours. To "turn on" the lamp, the user moves weights from the bottom to the top of the lamp. An hour glass-like mechanism is turned over and the weights are placed in the mass sled near the top of the lamp. The sled begins its gentle glide back down and, within a few seconds, the LEDs come on and light the lamp ... Moulton estimates that Gravia's mechanisms will last more than 200 years, if used eight hours a day, 365 days a year." The article contains links to the patents and the designer/inventor Clay Moulton's site." I think my laptop would require a slightly larger weight to pull this off.
