Rules for time travelers
Sean Carroll lays out the rules for time travel for movies (but also more generally) based on our current understanding of physics.
1. Traveling into the future is easy. We travel into the future all the time, at a fixed rate: one second per second. Stick around, you'll be in the future soon enough. You can even get there faster than usual, by decreasing the amount of time you experience elapsing with respect to the rest of the world -- either by low-tech ways like freezing yourself, or by taking advantage of the laws of special relativity and zipping around near the speed of light. (Remember we're talking about what is possible according to the laws of physics here, not what is plausible or technologically feasible.) It's coming back that's hard.
Star Trek
[Note: spoilers.] Bones did it for me. As soon as he sat down next to Kirk on the shuttle, I was hooked. Loved Star Trek, wanted to go again as soon we got out.
J.J. Abrams did something kinda crazy with the film though. He took the entire Star Trek canon and tossed it out the window. Because of the whole time travel thing, the events that occurred in The Original Series, The Next Generation, Voyager, DS9, and the previous 10 movies will not happen. Which means that in terms of sequels to this film, the slate is pretty much clean for Abrams or whomever he passes it off to.
Well. Almost. Events in this alternate timeline unfold differently but the same. Even though the USS Kelvin was destroyed with Kirk's father aboard, Kirk and the rest of the gang somehow all still end up on the Enterprise. But the destruction of an entire planet and 6 billion people should have a somewhat larger effect going forward.
Also worth noting is how the time travel in Trek compares with that on Lost, a show Abrams co-created and currently executive produces. On Lost (so far), the universe is deterministic: no matter who travels when, not much changes. Time travel can affect little details here and there, but the big events unfold the same way each time and every character remembers events unfolding in the same way, no matter when they are on the timeline. Star Trek's universe is not that way; characters before time travel events remember events unfolding differently. According to the older Spock, the Romulan ship going back in time changed things. Kirk knew his dad, Vulcan wasn't sucked into a black hole, etc.
On the excellent Bad Astronomy blog, Phil Plait doesn't cover the time travel aspect of the film but reviews the rest of the science in the film.
And yeah, we do hear ships whoosh as they go to warp and all that, but that's what we expect to hear, having evolved in an atmosphere which whooshes when things fly past us. I'd prefer that we hear nothing, but I accept that as a filmmaker's prerogative to make the audience comfortable.
But I'll add that for years I have complained about sounds in space, saying that done correctly, making things silent can add drama. That sentiment was proven here; the sudden silence as we leave the ship and fly into space with the doomed crewmember is really eerie and unsettling.
In the NY Times, David Hajdu tackles time travel of a different kind, arguing that the original Star Trek was not about science or the future; it was a nostalgic lens through which to view pop culture.
"Star Trek" was an early manifestation of our contemporary absorption with the pop culture of the past. The show's creator, Gene Roddenberry, was a gifted hack writer for TV Westerns like "Have Gun, Will Travel" and cop shows like "Highway Patrol," and "Star Trek," though set in a nominally stylized future, was essentially a Western cop show. In fact, Roddenberry pitched the series to NBC as "Wagon Train" to the stars; and, as Captain Kirk noted in his log, the ship would venture out on "patrol," cruising the galaxy like a city beat.
Steampunk GPS
Christopher Fahey on the watchclock, a device built to keep track of the movements of night watchmen.
The mechanism itself has barely changed for a century: although some more recent models incorporate GPS and other technologies, the mechanical key-based watchclock system is still in wide usage, with many buildings still employing the same keys and the same clockwork devices they've used since the 1940s. It's a genuine example of an "if it aint broke, don't fix it" kind of technology.

Flower and bee clocks
On the Zeitgedächtnis, or time-sense, of honeybees.
Flowers of a given species all produce nectar at about the same time each day, as this increases the chances of cross-pollination. The trick works because pollinators, which in most cases means the honeybee, concentrate foraging on a particular species into a narrow time-window. In effect the honeybee has a daily diary that can include as many as nine appointments -- say, 10:00 a.m., lilac; 11:30 a.m., peonies; and so on. The bees' time-keeping is accurate to about 20 minutes.
The time loop theory of Lost
Your Lost prep for the evening: The Time Loop Theory. Spoilers.
All of the "werid" things that we see happen in seasons 1 & 2 of LOST are a result of the Losties now existing in the year 1996 on the island. This is why Locke can walk, and why Rose is Healed -- their bodies are now existing in a time prior to them contracting their illnesses. This is also why some characters, such as Walt, have extraordinary perception -- because they're technically from the future.
This is Lost as Primer (note the Primer timeline map).

At 10:10, a watch smiles
Ten minutes past ten o'clock, which forms a smiley face on a clock and "frames the brand" nicely, is the go-to time for watches in advertising. Timex sets their watches to precisely 10:09:36 while Rolex waits almost a minute until 10:10:31.
The Hamilton Watch Company was among the first to clock in at 10:10; that time is favored in ads dating at least as far back as 1926. Rolex began consistently setting watches in ads at 10:10 in the early 1940s. Timex appears to have begun the transition in 1953, when its Ben Hogan model showed 8:20 while the Marlin model was set to 10:10.
Apple usually uses 9:42 am for the iPhone, which is approximately when it was introduced at MacWorld 2007. Until recently, the icon for Apple's iCal displayed July 17 when not in use; iCal debuted at MacWorld 2002 on that date.
Personal light cones
When I was born 35.2 years ago, a light cone started expanding away from Earth out into the rest of the universe (Minkowski space-temporally speaking, of course). Thanks to updates from Matt Webb's fancy RSS tool, I know that my personal light cone is about to envelop the Zeta Herculis binary star system, located 35.2 light years from Earth in the constellation Hercules.
With a mass some 50 percent greater than the Sun, however, and beginning its evolution toward gianthood (its core hydrogen fusion likely shut down), Zeta Her A is 6 times more luminous than the Sun with a radius 2.5 times as large. Nevertheless, the star gives a good idea of what the Sun would look like from a great distance, in Zeta Her's case 35 light years. The companion (Zeta Her B), a cooler class G (G7) hydrogen-fusing dwarf with a luminosity only 65 percent that of the Sun and a mass about 85 percent solar, orbits with a period of 34.5 years at a mean distance of 15 Astronomical Units (over 50 percent farther than Saturn is from the Sun). A rather high eccentricity takes the two as far apart as 21 AU and as close as 8 AU.
Hercules is of course named for the Greek hero, Heracles. Next up is Delta Trianguli, another binary star system, in about two months.
A fashion model for the ages
Vogue Paris has an editorial in the November 2008 issue which features a 20-year-old model photographed as if she were 10, 20, 30, 40, 50, and 60 years old. The hands betray her true age in the 40, 50, and 60 shots but the 10-year-old photo is a little bit of brilliance...just the right angle and lighting. (via the year in pictures)
For sale: Albert Einstein's watch
Among the watches being auctioned at a sale in October is a watch once owned by Albert Einstein.
For the Einstein fan, we have a Longines that was owned by the scientist himself. It is a unique and historically important wristwatch, made in 1930.The watch was presented to Professor Albert Einstein on February 16, 1931 in Los Angeles. It is a fine, tonneau-shaped, 14K yellow gold wristwatch accompanied by various photos showing Prof. Einstein wearing the watch. Estimate: $25,000 - $35,000
You'd think that the price for timepiece once owned by the man who changed our conceptions about time and space would be substantial, but it's one of the lower priced featured watches. And the price is not even close to the world record:
In 2002, Antiquorum established the all-time world record price for a wristwatch at auction when it sold a platinum Patek Philippe World Time Ref. 1415 from 1939 for an astounding CHF 6,603,500 (US$ 4,026,524). This record-breaking price more than doubled the previous world record price for a wristwatch at auction. Another record price for a modern watch was achieved in 2004, the unique white gold Calibre 89, also by Patek Philippe, was sold for SFr. 6,603,500 (US$ 5,002,652).

Younger than we used to be
While we're on the topic of The Curious Case of Benjamin Button, Andrew Sean Greer wrote a book with a similar premise published in 2004 called The Confessions of Max Tivoli. It was based in part on the same Fitzgerald story as Fincher's film.
Mr. Greer is candid about the precedents: F. Scott Fitzgerald told a related story in "The Curious Case of Benjamin Button," and that in turn was inspired by a remark of Mark Twain that the best part of life came at the beginning and the worst part at the end. Later Fitzgerald found "an almost identical plot" in Samuel Butler's "Note-books." In "The Sword and the Stone," which Mr. Greer read as a child, Merlin ages backward. Mr. Greer carries it further back, to Greek mythology, and forward to "Mork & Mindy," in which Jonathan Winters played a baby. And at one book signing, he said, a reader asked him if he knew about the "Star Trek" episode in which ----
Actually, when he began the book he was thinking more of Bob Dylan. In 2001, having published a collection of stories and in the middle of writing a novel, he found himself singing "My Back Pages" -- "I was so much older then, I'm younger than that now" -- and he had what amounted to an epiphany. "I thought that could be a book not like anything I'd written before," he said. "It sounded like a wild adventure that no one's going to want to read, but it could be a lot of fun, and maybe that's the point of it."
This passage from a NY Times review of Tivoli provides a good sense of what the tone of the film might be:
For when the repercussions of Max's reverse aging are eventually understood, the tragedy of his predicament becomes clear. Not only does he have the exact year of his death forever staring him in the face (1941, when he will complete his 70-year process of anti-decay), but he must also live his entire life, except for a few brief months in 1906 when his real and apparent ages coincide, being something other than what he seems.
Oh, and Shaun Inman quotes from Vonnegut's Slaughterhouse-Five about WWII moving backwards:
When the bombers got back to their base, the steel cylinders were taken from the racks and shipped back to the United States of America, where factories were operating day and night, dismantling the cylinders, separating the dangerous contents into minerals. Touchingly, it was mainly women who did this work. The minerals were then shipped to specialists in remote areas. It was their business to put them into the ground, to hide them cleverly, so they would never hurt anybody again.

Don't get me wrong, slugger. I love "More Than a Feeling." Those who don't are your basic a-holes. But it's like: We get it. The riff, the handclaps, the 10,000 multi-tracked guitars-nice.

Slow motion
Long rumination on the use of slo-mo in movies, particularly in Standard Operating Procedure. Being a slo-mo fan myself (especially when wielded by Wes Anderson or by NBC Sports during football games), I enjoyed this description of it:
Slo-mo can be a mesmerizing revelation of the grace inherent in the ordinary.
Slo-mo was invented and patented in 1904 by an Austrian priest-turned-physicist named August Musger. And who was working in the patent office in Austria in 1904?
My fantasy now is that Albert Einstein -- working in the Swiss patent office in Bern in 1904, when Musger patented slo-mo in (relatively) nearby Austria -- might have become aware of Musger's slow-motion patent (perhaps it even crossed his desk?) and that contemplation of slo-mo might have influenced Einstein's thinking about the nonabsoluteness, the relativity, of time.
Two other sort-of-related bits of Errol Morris news: 1) part 2 of his short series on re-enactments is now online, and 2) Morris will be talking about his new movie at the Apple Store in Soho on April 23 at 6:30pm. Prepare to wait in a long line. (thx, findemnflee)

How to think about the scale of human history: "Arthur M. Schlesinger, Jr., one the United States' great historians, is less than two lifetimes removed from a world where the United States did not exist. Through Mr. Schlesinger, you're no more than three away yourself. That's how short the history of our nation really is. Not impressed? It's only two more life spans to William Shakespeare. Two more beyond that, and the only Europeans to see America are those who sailed from Greenland. You're ten lifetimes from the occupation of Damietta during the fifth crusade. Twenty from the founding of Great Zimbabwe and the Visigoth sack of Rome. Make it forty, and Theseus, king of Athens, is held captive on Crete by King Minos, the Olmecs are building the first cities in Mexico, and the New Kingdom collapses in Egypt."

Daylight saving change and computer systems
Not too many people are paying attention, but the Energy Policy Act of 2005 lengthened daylight saving time by four weeks in the US. Instead of beginning the first Sunday of April and running through the last Sunday in October, daylight saving time will now stretch from the second Sunday in March to the first Sunday in November. The Washington Post has an article today about the change and what impact it might have on automated systems:
The change takes effect this year -- on March 11 -- and it has angered airlines, delighted candy makers and sent thousands of technicians scrambling to make sure countless automated systems switch their clocks at the right moment. Unless changed by one method or another, many systems will remain programmed to read the calendar and start daylight saving time on its old date in April, not its new one in March.
The article mentions that older Microsoft products like Windows XP SP1 and Windows NT4 might require manual updates and Daring Fireball has had a few updates about how the switch effects Mac users, including this piece at TidBITS. But what about everything else? Is the version of Movable Type I'm using going to make the adjustment? What about Wordpress? Perl? Ruby? PHP? Java? Linux? I'm sure the current versions of all these programs and languages address the issue, but are there fixes and patches for those running old versions of Perl on their server?
If you've got any information about programs, applications, and languages affected by the change and how to address the problem, leave a comment on this thread. I'll update the post as information comes in.

Bill and Ted's Excellent Adventure
I know I'm going to get mail about my five-star rating for this movie, but it cannot be helped. One summer when I was a kid, a friend and I watched Bill and Ted's Excellent Adventure -- no joke -- every single day for a span of 2 months. I still know every line by heart, the timing, inflection, everything. If there were a Broadway production of this movie, I could slide effortlessly into the role of either Bill S. Preston, Esq. or Ted Theodore Logan, no rehearsal needed.
In my high school physics class my senior year, we had to do a report on something we hadn't learned about in class -- which, I discovered when I got to college, was a lot -- and I did mine on time travel. I went to our small school library and read articles in Discover and Scientific American magazines about Stephen Hawking, Kip Thorne, quantum mechanics, causality, and wormholes. To illustrate the bit about wormholes, I brought in my well-worn VHS tape of Bill and Ted's (a dub of a long-ago video rental) and showed a short clip of the phone booth travelling through space and time via wormhole. I got a B+ on my presentation. The teacher told me it was excellent but marked me down because it was "over the heads" of everyone in the class...which I thought was completely unfair. How on earth is Bill and Ted's Excellent Adventure over anyone's head?
