American in Spain

Remember back when you were a child, and the world wasn’t so complicated and messed up? That was a simpler time, wasn’t it? WRONG. It was a simpler time for you, because you were a child, free to play and almost entirely free from responsibility. We live in the most peaceful time in all of human history. Thinking that things were better in the past is called the Golden Age Fallacy, and it annoys the crap out of me.

I’ve had my iPhone 4 for almost two years now, and it’s been at least six months since an app has really wowed me. The last one was surely Word Lens, the app that lets you point your phone at some foreign text, and it translates it right there on the screen for you. Okay, to be honest, Word Lens is quite a bit more technologically mind-blowing than the app I’m about to tell you about, but it’s been a while since I’ve pulled anyone over to say, “Hey, look what my phone can do!”

Back when the internet first began way back in yesteryear, there were many protocols (i.e. ways of transferring data). There was telnet for actually logging into command shells on remote servers; there was FTP for transferring files to and from remote servers; there was Gopher, which provided a very user-friendly system of menus to navigate to get to various information; and there was HTTP for requesting these newfangled documents with hyperlinks in them. Because of the interconnectedness of these hypertext documents, Tim Berners-Lee and Robert Cailliau coined the phrase World Wide Web. There was a previous long-standing practice of naming servers by the internet service they provided, so FTP servers had a “ftp.” prefix, Gopher servers had a “gopher.” prefix, etc. So naturally they started naming these “web” servers with a “www.” prefix.

I’ve always been fascinated by superstition, and friggatriskaidekaphobia – or, to be more clear, paraskevidekatriaphobia – strikes me as a particularly interesting one. The origin can only be traced back into the 19th century. I am disappointed to discover that experts find little reason to associate it with the slaughter of the Knights Templar on October 13, 1307, exactly seven hundred years before my wedding day. Oh well, something else Dan Brown got wrong. As if to show just how arbitrary the choice of Friday is, the Spanish speaking world fears Tuesday the 13th, and they even have their own tongue-twisting phobia word: trezidavomartiofobia.

During the months when the northern hemisphere of our pale blue dot on which I reside is leaning away from our stellar space heater, the light from our star enters my office window at sunset and distracts me from my work, causing me to get up and go to the window to shut the blinds. Depending on the formations of water vapor in the atmosphere, the view of the setting sun can be either boring and gray or spectacularly amber and crimson. Today, when I went to shut the blinds, I saw a lovely display of long wavelength visual electromagnetic radiation, which I felt compelled to take a photograph of.

This afternoon I was succumbing to a risky vice of mine, surfing the product pages over at ThinkGeek, when I came across this t-shirt where they had used chemical symbols for elements to write a dirty word. Silly, yes, but also kind of fun as a tool to separate people who know a lot of science from those that don’t, which seems to be the primary goal of the t-shirts at ThinkGeek. For instance, I always get a chuckle out of the one that says, “There are 10 kinds of people in the world: Those who understand binary and those who don’t.” Is that kind of elitist behavior rude? Yes, but it’s a social defense mechanism, creating an “us vs. them” mentality that is ubiquitous in our species.

When I saw yesterday’s Astronomy Picture of the Day, I was fascinated by just how big the Earth’s shadow is on the Moon. When I made a comment to this effect on Facebook, my friend, Josh Grady, said, “It’d depend on the distance between the two, no?” Of course the size of a shadow depends on the distance to the object its cast upon, but I hadn’t considered that the distance from the Earth to the Moon varies, due to its slightly elliptical orbit around the Earth-Moon barycenter, by 42,840 km, causing it to appear 12% smaller at its apogee than at its perigee. This raised the question: What are the minimum and maximum sizes of the Earth’s shadow on the Moon?

Four years ago, probably as a result of Nicholas Negroponte’s TED Talk, I became fascinated by the One Laptop Per Child (OLPC) program. I loved the idea of providing very cheap, easily networkable computers to third world children, since I know from personal experience how computers are so good for childhood learning. Before starting the project, they wanted to make a “one hundred dollar laptop”, built entirely on open source software. Unfortunately, they could only get the price down to $199, which is still pretty impressive once you learn all the features of the device.

Most of the wine I buy is not the dirt cheap young cosechero, the wine from grapes from last year’s harvest which is usually about 1.50€/bottle. Nor do I buy reserva from the best regions and vineyards, made from better grapes and kept in oak barrels for at least a year which sells for at least 10€/bottle. I normally buy crianza, the middle quality, from good regions (mostly Rioja) and good vineyards, wine which has spent at least six months in oak barrels and usually retails between 4€ and 5€. For the better Rioja vineyards, the grapes are so good that the cosechero, which has spent little to no time in barrels is almost as good as a crianza, at just under the price.

Apple finally launched their iTunes Match service this week. If you don’t know what that is, I’ll explain briefly. In the eight years since Apple opened their iTunes Music Store, they have been amassing an enormous collection of digitized music that they have the legal right to sell. If you buy a song from them, and your computer crashes, you can redownload that song again whenever you like, since, rather than a physical medium like a CD, what you’ve bought is the right to have that digital file.
