Two insightful articles

March 14th, 2011

In the midst of all the idiots clamoring for every nuclear power plant in the world to be dismantled in favor of smoldering coal plants, I thought I’d post some sanity. Both of these articles were written by engineers. An engineer is a person who deals with fact and reason on a regular basis. Dealing with reality means that engineers have to understand and plan for Murphy’s Law, and in fact expect things to go wrong. Considering that all the people who actually plan for* and expect disasters are engineers, they’re much more qualified to talk about it than most people. When we say something, we’re trying to inform. Your garden-variety news hack, on the other hand, is motivated by a desire to stir up a mess of emotion, because that’s what draws eyeballs. A “news story” is designed to be read in a minute or two, which rules out anything resembling an intelligent explanation of the relevant facts. This leads to ignorant discussion from the peanut gallery. And that in turn leads to public policy written and voted on by people barely competent to pilot an automobile, let alone grasp the inner workings of a nuclear power plant.

Human optics

April 23rd, 2010

I suspect this will only be of interest to a few of you, but if you work with photography or optics at all, it’s useful to correlate the performance of constructed optical systems with how the human eye works. What is the maximum resolution of the eye?

The following two links go over how human optical performance is measured, and the limitations in human optics. In a few ways, human eyes are superior to any CCD or CMOS sensor ever created; even in the presence of a very bright light source your eyes can detect a lot of detail in dark areas of the image. On the other hand, even a very basic consumer camera has a larger effective aperture than your eyes. It’s a very interesting read, and gives plenty of detail for jumping off into biology if you’re curious.

Now, Matt, I gotta say I had never heard of you before this afternoon. But, well…

Just take a look for yourself.

Really pretty inspirational if you think about it.
