The Climate of Middle-Earth
sciencehabit writes "One does not simply model the climate of Mordor; unless, of course, you are the University of Bristol's Dan Lunt, who has created a climate simulation of J. R. R. Tolkien's Middle-earth from The Hobbit and The Lord of the Rings. Using supercomputers and a model originally developed by the U.K. Met Office, his study compares Middle-earth's climate with those of our (modern) and the dinosaur's (Late Cretaceous) worlds. The Middle-earth model reveals that the Shire — home to the Hobbits — would enjoy weather much like England's East Midlands, with an average temperature of 7C and about 61 cm of rainfall each year. An epic journey to Mount Doom, however, would see a shift in climate, with the subtropical Mordor region being more like Los Angeles or western Texas."
The full academic paper is available in English, Elvish, and Dwarfish.
... that's not even badly transliterated. Without even looking at it closely, you can tell the entire text lacks vowel diacritics. They probably selected the text and changed the font, which works about as well with Tengwar as it would with Arabic or Hebrew.
Why yes, I suspect they were done "on the supercomputer's spare time." That's what "nice -n 20" is for. Most university compute clusters aren't running at 100% capacity 100% of the time --- there are gaps between intense clusters of jobs queued up by researchers. Without strong proof otherwise, I'd highly doubt that any other researchers had their schedules set behind waiting for Middle Earth simulations.
As for the electricity cost --- sure, someone may have spent a few tens of dollars there. For a result with high visibility and outreach potential, encouraging public attention to (and potential future participation in, via motivated youngsters) science. If you're so miserly that you don't think such expense is worthwhile, even just for putting a smile on many people's faces, then please fuck off; you're a miserable burden to humanity that would rather see everyone's life gray and miserable than dare spending 0.00000001% of tax money on anything you don't personally want.
No need. Orcs mostly speak the common tongue or else their own tribal dialect. The Black Speech -- as devised by the Dark Lord in elvish runes -- was a failed attempt to linguistically distinguish his followers from those of the Alliance. It didn't take among the Orcs, but strangely the East End London accent did.
May the Maths Be with you!
You're technically correct that "nice" isn't the command you use for specifying batch job priorities on a multi-node system (I also don't know what the specific setup of the University of Bristol's computational resources is). Nonetheless, there's typically some equivalent in the batch job submission system (and/or automatically enforced by per-user or per-group policies) for specifying job priority --- how many nodes to run at once, and what priority they are given against competing requests. Unless you have evidence otherwise, I'd consider it highly unlikely that Dr. Lunt's simulations were run in "use every single node the system has, while blocking all other requests" mode --- much more likely, they would have been trickled in to otherwise unused nodes, with negligible impact on anyone else's "real" research.
So, yes, these results were "funded" by the university --- at such minuscule levels compared to formal funding of personnel and resources that they will never appear above rounding errors. It was "funded" in the same sense that lights left on to illuminate campus walkways at night may provide benefit to pedestrians not at the moment engaged strictly in official university business.
As a member of the non-Ferrari-owning social class, I don't lose any sleep worrying that a non-multimillionaire might be permitted to have a little fun in life. For my own more meagre possessions, I'm perfectly happy to lend them out to friends and acquaintances while not in use; accepting a little uncompensated wear and tear on my books or electronics is a negligible price to pay for helping other people out, and living in a community of decent human beings (rather than being a spiteful multimillionaire incensed that a peon valet should enjoy more than misery).
Sure, ask my four year old son. Even before he flips the switch, the nearby coal burning plant has a turbine in a wye configuration that puts out a grounded three phase current. Over at the telephone pole, a transformer transforms it down, and two phases come to the house. One of those phases is tied to the light switch. When he flips the switch, the power is then transmitted -- at about a tenth of the speed of light, though the electrons themselves flow at a couple hundred mph -- to the light bulb. This being a fluorescent bulb, the voltage is transformed back upward through cheap junk capacitors, to a voltage capable of triggering the fluorescing gas. The gas then fluoresces according to the blackbody equations, somewhat in the UV, but heavily in the visible spectrum. The light produced sets up a series of changing electric and magnetic fields that then transmit through the air at something like ninety-eight percent of the speed of light in vacuum, to be absorbed by an electron somewhere in his eyeball. That then triggers an enzymatic chemical reaction, whic triggers nerve impulses that are set by the previous signal, and reset by the sodium channel.
Of course he knows all that; everybody knows all that. Otherwise, they might think it was magic.
