Submission + - Titan May Have Ocean (technologyreview.com)

olsmeister writes: In the seven years Cassini has spent orbiting Saturn, the spacecraft has sent back mountains of data that has changed our view of the ringed planet and its moons. Saturn's largest moon, Titan, has been a particular focus of attention because of its dense, complex atmosphere, its weather and its lakes and oceans.

Now it looks as if Titan is even stranger still. The evidence comes from careful observations of Titan's orbit and rotation. This indicates that Titan has an orbit similar to our Moon's: it always presents the same face towards Saturn and its axis of rotation tilts by about 0.3 degrees.

Together, these data allow astronomers to work out Titan's moment of inertia and this throws up something interesting. The numbers indicate that Titan's moment of inertia can only be explained if it is a solid body that is denser near the surface than it is at its centre.

Submission + - Could you pass Harvard's entrance exam from 1869? (nytimes.com) 3

erfnet writes: "The New York Times remembers back to when "college was a buyer's bazaar" and digs up 19th-century classified ads from Columbia, Harvard, Yale, and others. In competitive efforts to attract students from the limited pool of qualified candidates, applications were taken as late as September for an October freshman class. Vassar offered lush room accommodations. The expectations were high: Latin, Greek, Virgil, Caesar's Commentaries; Harvard's entrance exam from 1869 is posted (PDF): http://graphics8.nytimes.com/packages/pdf/education/harvardexam.pdf. Could any of us pass the exam today?"

Cosmological Constant Not Fine Tuned For Life 536

eldavojohn writes "A common argument one might encounter in intelligent design or the arduous process of resolving science with religion is that the physical constants of our world are fine tuned for life by some creator or designer. A University of Alberta theoretical physicist claims quite the opposite when it comes to the cosmological constant. His paper says that our ever expanding universe has a positive cosmological constant and he explains that the optimum cosmological constant for maximizing the chances of life in the universe would be slightly negative: 'any positive value of the constant would tend to decrease the fraction of matter that forms into galaxies, reducing the amount available for life. Therefore the measured value of the cosmological constant, which is positive, is evidence against the idea that the constants have been fine-tuned for life.'"

Archaeologists Find 2,400-Year-Old Soup 108

Chinese archaeologists have discovered a sealed bronze pot containing what they believe is a batch of 2,400-year-old bone soup. The pot was dug up near the ancient capital of Xian. Liu Daiyun of the Shaanxi Provincial Institute of Archeology says, "It's the first discovery of bone soup in Chinese archaeological history. The discovery will play an important role in studying the eating habits and culture of the Warring States Period (475-221BC)." No word on if the archaeologists also found the accompanying ancient crackers.

How Do You Get Users To Read Error Messages? 951

A BOFH writes "The longer I do desktop support, the more it becomes obvious that my users don't read anything that appears on their screen. Instead, they memorize a series of buttons to press to get whatever result they want and if anything unexpected happens, they're completely lost. Error logs help a lot, but they have their limits. I've been toying with a few ideas, but I don't know if any of them will work and I was hoping my fellow Slashdotters could point me in the right direction. For example, I was thinking about creating icons or logos to identify specific errors. They might not remember that an error is about 'uninitialized data' but they might be more able to remember that they got the 'puppy error' if I showed a puppy picture next to the error message. Or for times when finding images is too time consuming, you could create simple logos from letters, numbers, symbols, colors, or shapes, so you could have the 'red 5' error or 'blue square' error (or any combination of those elements). I've even wondered if it would be possible to expand that to cover the other senses, for example, playing a unique sound with the error. Unfortunately, haptic and olfactory feedback aren't readily available. I like to think that my users would remember the error that caused them to get a swift kick in the balls. And if they forgot it anyhow, I could always help them reproduce it. Does anyone else have experience with ideas like these? Did it work?"

Bethesda Announces New Fallout Game For 2010 254

On Monday Bethesda announced a new title in the popular Fallout series called New Vegas, set for release sometime in 2010. It's planned for the PC, Xbox 360, and PS3. They said it wasn't a sequel to the highly-acclaimed Fallout 3, but rather a brand new game set in the same universe, though they confirmed that it will be similar in style to Fallout 3. The new game will be developed by Obsidian Entertainment, a studio containing members of the original Fallout team, which Bethesda's Pete Hines discussed in an interview with Shacknews. The Fallout series also made headlines earlier this week when Bethesda trademarked the name for TV and film.

Bohemian Rhapsody On Old Hardware 137

eldavojohn writes "The sweet sweet melodies of Queen and the late Freddie Mercury are reproduced by hardware almost as old as the song is. 'There are millions of computers sitting idle at home consuming fantom electricity. Let's see where all that power is going. This is dedicated to all fans of Queen and hey let's not forget about Mike Myers and Dana Carvey of Wayne's World. Please note no effects or sampling was used. What you see is what you hear (does that even make sense?) Atari 800XL was used for the lead piano/organ sound, Texas Instruments TI-99/4a as lead guitar, 8 Inch Floppy Disk as Bass, 3.5 inch Hard drive as the gong, HP ScanJet 3C was used for all vocals. Please note I had to record the HP scanner 4 separate times for each voice. I tried to buy 4 HP scanners but for some reason sellers on E-Bay expect you to pay $80-$100, I got mine for $30.'"

Odysseus's Return From the Trojan War Dated 160

srothroc writes "Scientists have used astronomical data from the Odyssey to attempt to pinpoint the time of Odysseus's return from his eponymous journey after the Trojan War. From the article: 'The scientists then searched for potential dates that satisfied all these astronomical references close to the fall of Troy, which has over the centuries been estimated to have occurred between roughly 1250 to 1115 B.C. From these 135 years, they found just one date that satisfied all the references — April 16, 1178 B.C., the same date as the proposed eclipse.""
