Tuesday 06

Tuesday 06- I only did my stretches; I wasn’t feeling well today.
Today’s Weather was: Temps of around 42 and 63 degrees, NW winds 10 to 16 with MPH, humidity around 27 percent, mostly clear skies.
According to the National Weather Service: “Wednesday: Sunny, with a high near 67. North northwest wind between 7 and 15 mph, with gusts as high as 21 mph. Wednesday Night: Mostly clear, with a low around 46. North wind between 8 and 11 mph becoming calm.”
Kevin sent me a link to an astronomy blog written by Ethan Siegel that was very interesting but I have a problem with his no singularity theory, and that of inflation
Wikipedia Big Bang:
“On the other hand, inflation and baryogenesis remain somewhat more speculative features of current Big Bang models: they explain important features of the early universe, but could be replaced by alternative ideas without affecting the rest of the theory.[notes 6] Discovering the correct explanations for such phenomena are some of the remaining unsolved problems in physics.”
Wikipedia Inflation:
“Since the standard FRW big-bang picture can be fixed to match observations by a certain amount of fine-tuning, Earman and Mosterin reckon that this type of fine tuning is no worse or no better as an explanation of experimental results than the tuning you need to match a scalar inflation model to the same data. This conclusion is not shared by mainstream cosmologists,[citation needed] who view the fine-tuning of many causally disconnected patches to almost, but not quite, the same temperature and curvature as something that requires a dynamical explanation. This reflects a difference in philosophy, limits on fine-tuning have long been used by practicing scientists as criteria for a good theory, but are not given a central role in standard philosophies of science.”
The inflation model has always seemed to me like Ptolemy’s model of a Earth centered universe, have a problem just add more epicycles! Ptolemy’s model was even more exact than Copernicus’s Heliocentric model at describing orbits until Kepler came along with the right model.
Ginger called asking me to feed Princess, so I went for my evening walk down to Ginger’s listening to Astro 10: General Astronomy: Catastrophic Collisions.
I read aloud from the textbooks: “Astronomy Today” more about Mar’s surface; “The Cell: a Molecular Approach” about the human genome.
I started a new book by Jack Higgins called “Cold Harbour” about WWII and secret base in Ireland that ferries agents back and forth into Nazi controlled France. Our heroes captured and use a German torpedo boat and a plane for this purpose. It’s a few months before D-day and need this lady agent to infiltrate a Nazi meeting in France at her aunt’s mansion to get info on the Atlantic Wall’s fortification. But she is killed in a plane crash and now it’s up to our heroes to convince her twin sister, who is a nurse in London, to impersonate her sister and retrieve the plans. I’ve never read any of Higgins’s books so we’ll see how it goes.
I did my stretches and lifted weights, practiced my guitar, wrote to my journal, posted it to the web, and called it a night.

I am just a guy out in the desert amazed at the things out here where I live, the folks I call my friends, and this that we call the Internet. I am excited to share them with you!
