I watched an interesting video about the survivors of Hiroshima on CSPAN this weekend. While the main topic of the video was interesting, I was surprised to learn that there were a number of Americans POWs that were present at Hiroshima and died. They also mentioned an American POW that was near Nagasaki when it was bombed named Joe Kieyoomi. Joe, a Navajo soldier, has a war story that is almost unbelievable. Continue reading
Last week, I had a conversation with a coworker about a mystery that he just recently solved that I feel is worth sharing here. He has a small daughter who recently was found to have high lead levels in her blood. As any good father would do, he tried to find the source of lead in his home. His home is new, so there is no lead paint in it. They tested everything that their daughter drank or ate, and they found no lead in anything – yet her blood's high lead level persisted.

My wife and I are currently on an Alaskan cruise with friends that used to be our neighbors when our children were young. Our cruise ship is the Millennium, which is part of the Celebrity fleet. We are currently moored in Juneau, where we visited the Mendenhall glacier. While at the glacier, I talked with a local Forest Service guide about the rate of glacier melting. I also made a few measurements using my phone and a bit of math then ensued, which I will discuss here. Continue reading
I just watched an excellent documentary on Susan Oliver called The Green Girl. She played the character called Vina in the Star Trek pilot called "The Cage". Her photo in green makeup appears at the end of many episodes of the original Star Trek series (Figure 1). It appears that she had a sense of humor about all the makeup she had to wear in her role as Vina (Figure 2). I have revealed my love of all things Trek in previous posts (example), so my interest in this video should not surprise anyone. Continue reading
One of my favorite old movies is the "The African Queen" with Humphrey Bogart (he played Charlie) and Katherine Hepburn (she played Rose). In that movie, Rose asks Charlie "Could you make a torpedo?" and Charlie responds: "A torpedo?...You don't … Continue reading
I cannot tell you how often in 35 years of marriage I have come home to the open-ended question from my wife "Do you like it?", without "it" being defined. I then spend the next 10 uncomfortable minutes trying to figure out what aspect of my wife's appearance has changed. I admit that I simply do not notice things like haircuts, changes in hair color, new clothes, etc. I am so bad that I have even failed to notice a complete change of hair color (blonde to brunette).

It is cold in Minnesota right now and I hear the local motorheads warning people not to run their gas tanks down to empty. During winter, I hear this warning because of concerns that water vapor in the gas tank may freeze and cause the vehicle to stop. I also hear concerns about running on a low fuel tank during the heat of summer because the fuel is need to cool the fuel pump, which is often mounted in the tank. Some folks also say that there is corrosion at the bottom of the gas tank that get sucked into the fuel pump when running the tank near empty. Continue reading
