Thoughts on 3D
Hot on the heels of the movie Avatar, this year's CES was touting 3D as the "next big thing" in home theatre. Manufacturers, hoping to prolong the boost in sales they got following the conversion to digital flat-panel HDTVs, are hoping to convince consumers, in a few years, to go through buying a whole new TV in order to view things in 3D.
Obviously, it's going to be a hard sell: while football in 3D might be tempting, needing to buy a dozen pairs of glasses in order to have a super bowl party hardly seems around the corner, notwithstanding the fact that not many people want to be seen wearing 3D glasses when there are other people around. At least at the movie theatre everyone is in the dark!
Rather than tread the ground most commonly covered, though, I want to weigh in on the whole discussion with two things I recently saw, one from the distant past and one from the "future".
I'll start with the future, since I'm disregarding the conventions of chronology anyway! This is the technology that allows TVs to be in 3D without wearing glasses. This exists, I've seen it at tech conferences, and it works, although it can make you queasy. It also adresses the problem of wearing goofy glasses that I mentioned above. Is it the future, though? Maybe someday, but for now the costs put it much farther into the future than the technologies currently being touted by television manufacturers. And while it does work, it is nowhere near as impressive as 3D in a movie theatre, for the simple reason that the screen is smaller. The 3D image can only go as far as the screen frame, you see, so it is not possible to have things flying all around you the same way they do at the theatre: depth has to be reduced just like the height and width of the picture, with the result that the 3D effect is that much less impressive. (In other words, this picture is totally fake—it is impossible for the shark's fin to cover up the frame of the TV!) You don't have things flying all around the room; it's more like your TV becomes the frame of a diorama. This is just as true with the systems that use glasses as with those that don't.
The other thing I saw recently was a museum of World War I memorabilia. In addition to guns, uniforms, and gas masks, it also had a large collection of stereoscopes, which displayed slideshows in 3D of a number of fascinating pictures taken during the war. Seeing this made me realise two things. Firstly, that 3D is nothing new. The stereoscope has been around since 1840. But it hardly managed to dislodge the photograph to become the "next big thing".
Second, while 3D images are fun to look at, they don't really look like reality does. In fact, the 3D we get from perspective in an ordinary photograph is just as true to what we see when we look around in the real world as a 3D image is. This may seem counterintuitive, but it is true: the reason is that in a 3D stereoscope or movie, you can't actually see around things: the 3D you see is what was filmed by the cameras. So when you tilt your head, things move in 3D, but in an odd way that is not like what happens when you move your head in a real room. In real life if I tilt my head while looking at a tree trunk, I can see behind what I was looking at before. In a 3D movie, the whole scene shifts so that I still see the same things as before. I can't see behind anything, because both the foreground and background re-arrange themselves to present the same picture again. It's a neat effect, but it's nothing like reality.
True "3D" in imitation of reality requires a hologram, which actually does record an image from multiple angles. I have seen, in a museum, holograms in which enough angles are recorded that you can walk all around them, and they are quite a feat, despite not being in full colour. But even a 5 second "animation" in a hologram takes a huge amount of time to create. Holographic movies are decades away, I have to think. Besides which, the "animation" is played by walking around the hologram. I am not aware of any way to play a holographic "movie" in the way we are used to thinking of movies today. Advancements are needed not only in technology but in science before we can seriously consider this as a future possibility.
So anyway, I thought those points were worth sharing on the topic. I do enjoy 3D movies and will continue to see them, but it is important to realise that they are nothing new, not as impressive on a small screen, and not actually more realistic than 2D movies. All of which leads me to believe that we will not be replacing our existing HDTVs any time soon.
What we were wrong about, though, is being afraid to brave the Edinburgh Festival with a small child. It is actually a great time to visit the city, even with a baby. The crowd situation, which I had imagined being something like the
So on Saturday we elected to start the day with a visit to the
This was just amazing. If you have an appreciation of railroads, and what goes into running them—even the amount of effort that goes into getting a small N-scale layout model railroad up and running—then you will likely be flabbergasted by how much British railway enthusiasts have been able to do. And Bo'ness is not even the only example: in planning our trip there were multiple similar sites across Britain that we might have gone to, but this was the best fit for our itinerary, and looked like one of the better ones.
Both texts are chosen by teachers because of their style is clear and direct (and therefore not too confusing for beginners), and because their style and vocabulary are considered exemplary by the standards of classical prose for the two languages.
Xenophon cannot be put on the same level, in my opinion. In fact I suspect that were I teaching Greek I might use Plato's Apology and Symposium as my baseline texts for Attic prose. (I think it might also be cool to compare and contrast Xenophon's and Plato's Apologies, but I haven't gotten around to doing this yet myself, so I can't vouch for this approach.) They are sublime stylistically without being too difficult, and the lessons they teach are perhaps of greater use to beginning students. The Anabasis is an adventure story, very exciting, to be sure—but you have to be able to read Greek at a certain level for a page-turner to be a page-turner!


What really sealed my willingness to be open to this game, though, was the fact that my go-to "coding music" is in fact a 31-minute long live mix by Japanese DJs Denki Groove (the opening of which can be seen
It's been a while since I've written a James update, but that isn't because he hasn't been growing! He now feeds himself, and is starting to talk—in both English and French! A lot more French than English, but unfortunately that is to be expected since his mother and day care both speak French to him, and he only sees me for about 20 minutes a day on weekdays. So the only things I've heard him say in English so far are "ball", "shoes" and "bye-bye"—and just today he repeated "I love you" back to his mother, which had her bouncing with joy :-) In French he can say "au revoir", "regarde", as well as "nez", "bouche", and probably about a dozen other words, although not all of them with much regularity.



When you go to campgrounds in the US, you will see some Winnebagos with maps of the United States on the side, with the states coloured in where they have stayed. These hardcore campers working their way across the lower 48 states have always impressed me, both by their dedication to the RV lifestyle, and for having such a developed, deliberate way to organise their travels. Likewise, some people have a particular type of souvenir that they collect; these collections are then a convenient way for them to look back on their travels.
Don't get me wrong, this does not mean I am going to force every family vacation to fit into an opera pilgrimage. But it does give me a new orientation and motivation for my future travels, and since we went to the Kirov on our honeymoon (pictured at right), I can 'retcon' that trip into this new framework as well.



... Juno, æternum servans sub pectore vulnus,


So on the afternoon of the fourth day, we left the United Kingdom and set sail for Ireland. The Holyhead-Dublin route is the most direct route to Dublin from Great Britain, and as such it is one of the most heavily-traveled ferry routes in the world. As a result, the ship we sailed on was huge—in fact, the largest car ferry in the world by capacity: Irish Ferries' Ulysses. I was glad to be able to book this ship because travelling in this manner made what would otherwise just be a matter of getting from point A to point B into something of an event in itself. Our ship was massive, and included a movie theatre, shopping area, restaurants, casino, video arcade, and children's area.
If I thought it was exciting to board the Ulysses, though, that was nothing compared to the rest of the family! Emilie found us a lot of great Irish-themed souvenirs in the shops (including some Irish socks that James still smiles and points out to us every time we put them on him), but by far the biggest fan of the ship was our toddler. James loved this part of the trip—more than anything else we did and more than anything else we've ever done with him, really. The playground kept him occupied from the time we boarded until it was time to go—he even skipped his afternoon nap, to our slight chagrin. But we were happy to see him have such a good time.
For those without children, the movie theatre must be a great way to sail to Ireland. Having two hours of the voyage taken up while seeing a movie must make the trip fly by, but for parents with young children like us we were not able to partake of that particular luxury.





The order of business for this day was to get our British rental car, head to Witney (a charming little town west of Oxford) with both cars, where we had arranged to park our French one, then head north in the rental car, reaching Bangor, Wales, by evening. Deepest thanks to the West Oxfordshire District Council for allowing us to park in their long-term parking lot at the centre of town for longer than is usually allowed!
I have explained before my
The ukulele quickly fell off the list, though: it's primary advantage to me had been low cost (again, since I'm not that serious about my music I'm not going to spend $900 on an instrument), but looking around I was able to find that there were viable guitar options which were not that much more expensive than a ukulele (the Yamaha C40 classical guitar, for instance), and would offer a lot more options musically. The uke is also easier to learn than the guitar or mandolin, but I don't expect them to be particularly hard, either, so that was not a major factor.
So, in the steel-stringed, folk acoustic category, my attention went to the Yamaha F310, which is not that much more expensive. I would have thought that this is where the search would have ended (and I can't promise I won't end up getting one eventually), but a few factors drew me to continue looking and to consider the mandolin.
What finally decided me, though, was the discovery of how good the mandolin sounds standing in for the balalaika (itself not a very versatile instrument and so not one of my contenders, even though I like Russian folk music). Adding Korobeiniki and Kalinka to my potential repertoire meant that there were now a lot of things I could see myself actually learning on the instrument—more really than I had in mind for the acoustic guitar—and all this on an instrument that would be smaller, cheaper, and easier to learn—but still able to play chords and improvise on without external accompaniment, and all this while being somewhat unique to boot.



I had been playing Spinal Tap's famous rock anthem in the weeks leading up to the trip to get me in the mood for our trip, and it was to the ancient monument in Wiltshire that we set out first, an hour and a half's journey from our hotel (there are a lot of hotels nearer to Stonehenge, but I wanted to stay near Oxford, since we were visiting there too and would head north to Bangor next).
