New Post: "The Great Sin of the Left"

Hello all.  A new post  on The American Catholic: "The Great Sin of the Left," which is to make us hate them because of their lies, corruption, .... and violate the teachings of Jesus, to love our enemies (Matt 5:44).

New Post: Faith, Decision Making and Probability III:
Bayes' Theorem and the Anthropic Principle

Hello all.   New post on Catholic Stand: "Faith, Decision Making and Probability III: <br>Bayes' Theorem and the Anthropic Principle."  I  derive Bayes' Theorem and discuss two examples of how it is used to incorporate new knowledge into modifying probability as a measure of belief:  the Monty Hall problem (the three doors with a prize and goats), and a medical test for a rare disease.

New Post: "Faith, Decision Making and Probability II: How do we interpret probability?

Hello all.   Hope you're welcoming fall, and cooler weather.   A new post on Catholic Stand: "Faith, Decision Making and Probability II: How do we interpret probability?"   I talk about the various interpretations of probability--logical, frequentist and subjective--and how probability is conditional, based on evidence.

About Me

Retired, cranky, old physicist.   Convert to Catholicism in 1995.   Trying to show that there is no contradiction between what science tells us about the world and our Catholic faith.   Intermittent blogs and adult education classes to achieve this end (see http://rationalcatholic.blogspot.com/   and http://home.ptd.net/~rkurland)

Extraordinary Minister of Communion volunteer to federal prison and hospital; lector, EOMC.
Sometime player of bass clarinet, alto clarinet, clarinet, bass, tenor bowed psaltery for parish instrumental group and local folk group.

And, finally, my motivation:
“It is also necessary—may God grant it!—that in providing others with books to read I myself should make progress, and that in trying to answer their questions I myself should find what I am seeking.
Therefore at the command of God our Lord and with his help, I have undertaken not so much to discourse with authority on matters known to me as to know them better by discoursing devoutly of them.”
St. Augustine of Hippo, The Trinity I,8.
