Today, Daddy decided to teach me a little bit about his favorite subject, it's something called entropy (or "s" as he would call it).Apparently, as Daddy would say, entropy is a measure of disorganization of the universe. He says that the rate of change of entropy in the universe is greater than zero. However, he tells me of a process called an "isentropic process" where the change in entropy is zero. He says that perhaps locally the change can be zero, but always to remember that for a real process, the overall change of entropy in the universe will always be greater than zero. Now, he says that an example of this isentropic process is the "ideal cycle". He says that entropy can be described by the following equation:
. This states that the amount of energy in the form of heat that crosses a control volume must be the same or smaller than the temperature of that control volume times the amount of change of energy within that volume... Actually, Daddy just corrected me on how to say this (he does have a PhD, ya know), he says that the amount of change in the entropy within a control volume will always be at least the same (if not larger) than the amount of heat energy which crosses the border divided by the temperature of the surface by which it transfers. He also wants to point out to me that always to remember that the temperature should be expressed in terms of Kelvin, unless you are an English units baby, where it should be expressed in terms of Rankine.
Daddy does say that because of entropy, time can only go forward. I really do not understand this but he insists that this is the most important contribution of the Second Law of Thermodynamics. He read to me this book called Energy, and I was totally intrigued by it. He told me of all the great scientist who tried to deal with the subject, including a Frenchman who didn't own a car (Carnot), and a cool Scottsman named William Thompson (who is also named Lord Kelvin).
Daddy is a total fan of Lord Kelvin, who he said was a really smart guy. However through my research, I found out that Mr. Kelvin thought that the Sun derived it's power from the impact of hundreds of thousands of meteors hitting it all the time. Now, I may have just been born yesterday (well, 6 1/2 weeks ago), but that is a pretty funny thought. Daddy also tells me that the town of Kelvin near his hometown of Kearny is named after Lord Kelvin, because back in the 19th century Kelvin was a major sponsor of mining in Arizona.

So, Daddy just wanted to show one more picture, I had what he calls an 80's preppy moment, what I say is I am just my father's son, as I found out from Daddy's friends at work that he forgets to put his collar down when he walks into the lab. I am a big boy now, I weigh 11 lbs 3 ozs now, and I was measured to be about 23 1/2 inches head to toe. I can't wait until I get to be 2 feet tall.
Now, Mama and Daddy are taking me to a drive in Movie to go see my namesake James Bond.
I can't wait to see my first movie, it will be pretty awesome. I hope to see you all soon,
Love,

Ashton James (Bond) Nebeker
