I'm an electrical engineer, but I've enjoyed writing poetry. I'd like to try my hand at writing non-technical prose.

Background Information

Dixon Wall Coulbourn is a retired electronics engineer.  He and Gail will have been married 54 years in August, 2012.  Gail is a retired English teacher.  They like to take hourlong hikes, (but only on days that end in "y"), swim, do crossword puzzles and jumbles.  They are both interested in words and language.  Gail knows some Spanish, and Dixon is learning it.  Except for Sunday, most days, they read the bible in English/Spanish for about an hour.  It's a great way to learn a language and refresh the memory of the Bible.  Dixon has studied seven languages, but all he can speak is the governor's English, as long as he is an Aggie.  Dixon is into genealogy, as were his parents.  Other family interests are Shakespeare's plays, Gilbert and Sullivan's Operettas, Marx Brothers Movies and Texas Aggie sports.  Both Dixon and Gail enjoy going to Red River Church, where Dixon plays harmonica in the band.  "Ensemble" would be more appealing.    Dixon has recently been writing poetry.   He is also interested in astronomy, physics, bridge, and chess. Dixon Long Coulbourn was his father.  Katherine Louise Wall Coulbourn was his mother.  Dixon Edge Coulbourn was Gail's and Dixon's oldest son, but he passed away in 2005.  Their two other sons are living and married, but to protect their privacy, we'll not mention the names of the living, except Gail.  They have one grandson and 3 granddaughters.

Patent No. 5253221. Poems about our grandchildren, ©Little Maggie With Reddish-Yellow Hair, ©Calvin Wall Coulbury. Fired Expert in Rifle and Carbine. Participated in Boston and Pike's Peak marathons. Best marathon 3:05:01, Woodlands, TX Cool & flat! That's 7:03 per mile. At this writing, my best two miles lately is slightly less than an hour, using a cane on the hike and bike trail, with Gail.

Additional Information

I read like a proofreader, and found errors in a couple of books. I sent the comments in, and the authors responded very positively, and fast. I helped my supervising professor, a Croatian, with some of his writing. We also helped our god-daughter with proof-reading part of her thesis, I hope.

Forces on the moon due to the sun and the earth
The Forces on the Moon due to the Earth and the Sun Earlier, I had calculated the forces of gravity and centrifugal force acting on the moon due to the earth and the motion of the moon relative to the earth. I had assumed that the forces would balance at some radius, and the resultant force would be just right to make the orbit stable. But whenever I considered the vectorial sums of forces, the result seemed to move the moon away from what I thought was the stable point. Then I realized I had ignored the forces due to the sun, which turned out to be about twice the force due to the earth. The two forces I had ignored were the gravitational pull between the sun and the moon and the centrifugal force due to the earth and moon in rotating around the sun. The gravitational pull is easy. It’s (G X m(M) X m(S))/R squared, where G is the universal gravitational constant, which is multiplied by the mass of the sun, multiplied by the mass of the moon, all divided by the square of the distance between sun and moon. The centrifugal force (or is it centripetal?) is more complicated. The force is given by F = m(M) X v squared over r, where v is the orbital velocity of the moon around the sun. Since the moon is simultaneously rotating around the earth, the moon’s orbital velocity around the sun is the vector sum of the motion of the moon and the motion of the earth. At the same time, the forces of gravity between the earth and the moon and the centrifugal force due to the orbital velocity of the moon around the earth are still acting. Each component of these forces is fairly simple. The earth moves around the sun in a slightly elliptical orbit, from perihelion to aphelion and back to perihelion, where the perihelion is 1.4709 times 10 raised to the 20th in meters, and the aphelion is 1.5210 times 10 raised to the 20th in meters. And, if this doesn’t pan out, we may need to consider the rest of the universe....I Googled on “the rest of the universe,” and found out that astronomers can find only 4 % of the mass of the universe. The rest is called dark matter and energy. Fred Heeren, the author of Show Me God, got me interested in this. After I had read his book the second time, I needed clarification of a point or two. I found his address by Googlation and wrote him a fairly long letter, at 20 wpm, and he responded rapidly, and was very encouraging.

Book 4: The Nublis Chronicles: Golden Silence by Kate Saundby

Shattered words, trust abused, maimed and slowly dying, who will hear the soliloquy of the silenced?..
