Scare Crow? Nope, this Girl has a Brain

I work with people in the nuclear energy industry. My goal is to ensure everyone I work with ends up being a better member of the industry. Smarter about how things need to be done, or why things should be done. BUT, there’s much more to nuclear technology and today, I got a reminder.

Go back a year. I was working at my desk, talking to a client on the phone. Suddenly, I felt extremely nauseous. Hanging up the phone, I ran for the bathroom. A few minutes later I had a blinding headache as well. Needless to say, this was very frightening. I just wanted to curl up into a ball. My husband insisted on a trip to the Emergency Room.

The hospital discovered I had a resting pulse of 40. While elite athletes might have such a pulse, I’m a 54 year old woman who rides a desk chair most of the day. All of these things left the ER doctor fairly puzzled. But a big concern was that I was possibly having some kind of brain malfunction.

I don’t know about you, but I rather treasure my brain. I find it generally useful for a variety of things and I want to keep it fairly intact. The doctor agreed that I needed to keep my brain in good working order, but he needed to get a look at what might be going on.

Not many years ago, that would have meant a fuzzy x-ray and possible exploratory brain surgery. OR the doctor would have administered drugs “just in case” to prevent anything further. Now, however, he ordered a CT scan. They dosed me with a contrast chemical (no not radioactive, this time) and put me in this cool circular machine and did a detailed 3D scan of my head.

Sure enough, I still had a brain! I was not the Scare Crow after all. Even better, it all seemed to be working properly. They did find a small something on the back of my head. The doctors agreed that the small something did not cause my symptoms, but wanted to keep an eye on it.

A year later, my regular doctor asked me to have another CT scan to make sure the little small something was still just a little small something. So, today I went in to the radiology folks. In 15 minutes, they had once again scanned my brain and confirmed it was there. I’ll know in a few days what the results are, but I already know that life is good and nuclear technology made it better.

What was wrong a year ago? I may never know. Dehydration? Possibly. A random migraine? Never had one like that, but my father suffered from them for years. What I do know, is that nuclear technology made my life so much better and prevented potential major surgery.

Nuclear technology makes our lives better. Nuclear medicine allows diagnoses and treatments that used to require risky complex surgeries with weeks of painful recovery. Radiation treatment sterilizes our food supply without dangerous chemical residue and prevents food-borne illnesses. Nuclear energy gives us electricity without spewing toxic chemicals into the air. We need to tell the world.

Vacation Blog #1: Of watches and ships

Thursday Sept 15th, we left Wilmington for a 12 day cruise from Vancouver, BC to Hawaii and around the islands. We’ve been planning this trip for more than a year as 2011 marks our 25th wedding anniversary! In honor of being on vacation, I’m doing blogs for the next two weeks that have little to do with my normal areas of expertise, but are more philosophical and more creative (I hope)

As I lay awake the night before, I was thinking that I should take a watch. I haven’t worn a watch in over a year for various reasons. My cell phone has sufficed as a kind of oversized pocket watch. But on board ship, especially for the several days of open cruising, the cell phone is somewhat superfluous – except for telling time and playing “Angry Birds”.

So in the morning I dug around and found my wristwatch. Of course, the battery was dead. At 5am, I didn’t think I’d find any place open to get a new one. I thought about bringing the watch along and hoping I’d have time in an airport, or something to get a battery. Then I remembered something special.

Way back when we married, we managed to take our honeymoon in Europe. A few days each in London, Geneva, and Zermatt, and finally a week in Zurich. I pretended to work in Zurich and my employer paid for my airfare and our hotel in Zurich. As my wedding gift to my husband, we shopped on Bahnhofstrasse for a special watch. We thought being in the land of the famous Swiss watchmakers made it the appropriate gift.

Pocket Watch

Pocket Watch

We purchased a beautiful pocket watch with a clear casing and watch face so that you can see the inner workings. The hours are not marked except a small indication of 12 o’clock, so one only knows the approximate time. Mark has never used it much, because such a watch demands the right kind of clothes to wear and Mark never really liked wearing a vest with a watch pocket.

However, for this trip, it is perfect for us. I wound it up and tucked it into my jeans watch pocket and fastened the chain around a belt loop. While waiting for a flight, I was studying it again, such a precision instrument and yet such an old technology. I began thinking about the beginnings of watches and why they were invented in the first place – to keep accurate time on sailing ships so that they could know where they were even without a coastline.

You see without an accurate way to tell the exact time, mariners couldn’t take a reading from the stars or the sun and know where they were from east to west. They could always tell how far north or south they were by the declination of the sun at noon (the sun’s highest point in the sky). But the early explorers were never exactly sure where they were in longitude without accurate timepieces. To be sure, there were a number of very accurate clocks in the world in the 17th and 18th centuries, but they used gravity and/or pendulums to maintain accurate time. On a swaying sailing ship, these devices were useless.

So the British Royal Society offered a huge prize for the time for someone to invent a timekeeping device that would work on the rolling decks of a sailing ship. The prize stood for many years until a carpenter named John Harrison invented a spring balance system in 1730. His first designs didn’t work as well as needed and the Royal Society couldn’t believe someone from such a lowly profession could have created such a complex device. So he kept refining it and finally in 1761 he submitted a winning design. As he continued to refine it, he ended up with something that looks a great deal like a modern pocket watch. The prize was £20,000 (several million dollars in today’s currency).

This invention allowed a huge leap forward in the ability of exploration and commerce to move around the globe. The ability to know precisely where one was made it possible to travel more swiftly and safely across large stretches of open ocean thus expanding the British Empire into Asia and the Americas much more rapidly that they had been able to before.

Civilization changing inventions don’t come along every day and many times civilization doesn’t recognize them when they do. Clocks had been around for a long time slowly increasing in accuracy and decreasing in size, but Mr. Harrison took a different look at things and realized there had to be a way to make a chronometer that was both compact and accurate. He kept working on it until he was successful.

As we look back in history, we can see these major inventions and their impact pretty clearly. Gutenberg’s printing press, Samuel Morse’s telegraph, Alexander Bell’s telephone, Edison’s light bulb are among those inventions that changed the world. What inventions of recent times are equally world changing?
