Ukraine Travelogue, part 1: Travel is hell!

Well, I’m back in Amsterdam, having finally gotten out of the Ukraine. I thought I’d post a number of random observations about the country, the people, and the culture, in addition to posting a bunch of pictures.

Overall, I had a very good trip. The meeting in Chernivtsi, Ukraine went extremely well, and I developed a number of important new contacts, planned new collaborations, and made new friends. I was even surprised to have one of the ‘distinguished founding fathers’ of singular optics, who was presiding the session in which I spoke, stand up and declare that my talk was ‘the best of the conference’ (I was tempted to immediately point at a friend of mine who had spoken before me and shout, “In your face!”, but I didn’t think people would realize I was kidding).

The Ukraine is an interesting country in that it is one that is struggling with modernity and what you might call ‘civil society’. Though of course many people there are good, civilized sorts, there is also below the surface for many people an attitude of ‘every man for himself’ which doubtless comes from a society which has been poor and oppressed for a long, long time.

Hi from Kiev!

Hi everyone (anyone?)! I just thought I’d write and say ‘hi’ from Kiev. I have to pay for a half-hour of internet anyway, so I’m filling the time!

Kiev is a magnificent city, and I’ll have many pictures to put up when I get back. I walked pretty much the entire central downtown area, which means my legs and back are extremely sore.

I was pleasantly surprised that I could find my way around easily. Once I got going, I only had to glance at the map every once in a while to make sure I was on the right track, and I never made a wrong turn. I even found a particular metro station that I wanted to write about! (More later.) I guess my previous time in Kiev stayed in my memory.

(To my girlfriend: see, I DO have good direction sense!)

Man overboard!

Just a little anecdote while I’m on the road… I head to the Ukraine tomorrow, and I’m not sure what will happen there (hopefully fun).

Anyway, on my way to meet my old boss, I had to stop and take a picture of a particular bridge in Amsterdam which has a special meaning to me. It is pictured below:

Greetings from Amsterdam!

Well, my girlfriend and I have been floating around Amsterdam all week. The weather is pleasantly cool, unlike the heatwave much of the U.S. has been suffering through.

I’m putting together some awesome panorama shots which I’ll display once I return from the trip. In the meantime, here’s a couple of random pics I took while out and about.

Optics basics: The three major branches of optical science

Since this is supposed to be in large part a science-focused blog, I wanted to get started with some serious posts about scientific topics. Like most of the established science bloggers, I’ll be mixing up posts which are on basic scientific concepts and posts which are on specific, technical, topics. This post will be one of the former.

My physics specialization and area of research is optical science. Though most people associate the word ‘optics’ with the engineering of lenses for eyeglasses, telescopes, and microscopes, in physics the term more broadly refers to the study of the behavior of light and its interactions with matter. The connection to eyeglasses and the like is not accidental, however: the development of various optical tools led scientists to study more closely the behavior of the light that those tools channeled.

Today, we may roughly group the study of optics into three broad subfields of study:

  1. Geometrical optics, the study of light as rays
  2. Physical optics, the study of light as waves
  3. Quantum optics, the study of light as particles

Let’s look at each of these subfields in turn, both historically and scientifically.

Temporary slowdown

I hate to do this so soon after starting my blog, but I’ll be having a posting slowdown over the next few weeks as I travel on business to Amsterdam, the Ukraine, and then San Jose. I’ll try and throw in a few insightful posts (with pictures) of the various places I end up…

… the Hell? Republican sex scandals

Yet another Republican politician has resigned in the wake of a sex scandal. Sen. Larry Craig, R-Idaho, was arrested in June for apparently soliciting lewd conduct in an airport men’s bathroom. He pled guilty to the charge of disorderly conduct. The details of the case were only revealed this Monday.

There’s been a rash of Republican sex scandals in recent years, indeed a staggering number of them. Most publicly we have the Mark Foley scandal, in which the Republican congressman was caught trading sexually explicit electronic messages with underage former congressional pages, which led to a resignation. More recently, we have Florida Republican Robert Allen arrested soliciting sex in a public park. There are numerous others.

Abu G outta da house… (updated)

Alberto Gonzales has resigned. I can’t say I’ll miss him, and it’s already been noted that there really isn’t anyone, outside of the president, and maybe Cheney, who’s sad to see him go. It’s important, though, as our brains flood with serotonin, to keep in mind exactly what sort of person we’ve gotten rid of:

Exciting film projects which may never get made…

Here’s an interesting tidbit for Robert E. Howard fans: an animated film version of the Conan story Red Nails is in production.  I stumbled across the web site for it a few weeks ago, and it looks like it is aiming to be a truly faithful adaptation of the original story.  To get really excited about it, just look at the cast, and in particular who’s been chosen for the voice of Conan.  (This actor would probably be a great choice to play Conan in a live-action movie, except that he probably couldn’t muster up the full mane of black hair any more.)

The only problem?  The film has been in production for quite a long time and it’s unclear if production has been halted or not.  The movie blog, which was supposed to be updated every two weeks, hasn’t been updated since June.  Here’s hoping it gets released — it would be nice to see a proper depiction of the barbarian, which doesn’t depict him as a steroid-addled buffoon or part of a ‘Conan and friends’ ensemble.

Films too good to describe

All the talk about the movie Hot Fuzz in my earlier post got me thinking about another curious category of movie.

First, let me say a few words about Hot Fuzz: it’s an action film parody/homage by the same people who brought us the exquisite Shaun of the Dead. The story begins when a far-too-competent London police officer (Nicholas Angel) is reassigned to a quiet little small town because he’s making his colleagues look bad. Once he arrives in the small town, a series of grisly murders take place, and Angle’s investigation finally culminates in some explosive action.
