“Truth Cannot Contradict Truth”
All about Science and the Church

Science can purify religion from error and superstition; religion can purify science from idolatry and false absolutes. Each can draw the other into a wider world, a world in which both can flourish.”  St. John Paul II, Letter to Rev. George Coyne, S.J., Director of the Vatican Observatory.


The video above, “From the Big Bang to Hubble,” is put out by EESA (the European Space Agency) and is featured, among other bells and whistles, on the home page of my new web-book “Truth Cannot Contradict Truth.   Here’s what I’m trying to do with this, as set forth in the Preface:

What!—another book about science and the Catholic Church; who needs it?”

That was the question I asked myself as I thought about writing this ebook. Six months earlier I had published an ebook about science and Catholic teaching; “Science versus the Church—‘Truth Cannot Contradict Truth’”. I wrote it to demonstrate that there was no conflict between what science truly told us about the world and Catholic teaching. A few months after that, a very fine book (hard-copy) “Particles of Faith” by Stacey Trasancos came out, with the same goal and theme. And some 14 years ago, a classic work by Stephen Barr, “Modern Physics and Ancient Faith” had appeared, to mention just a few titles.

Well, here was the problem: I had taught several adult education courses on science and Catholic teaching for the Diocese of Harrisburg and had given talks locally about the subject. A great difficulty in this enterprise was that some students, adults, lacked the basic scientific knowledge needed to engage meaningfully with the proponents of “scientism” (the atheology that says science explains everything we need to know about the world); and I didn’t have the skill to impart these basics in the limited course time available. This lack was not only a concern for me, but is general, according to this headline in the U.S. Catholic, “Should Catholics get an F in science?”

So, my remedy: a book that proposes to give a background in the basic sciences, on a qualitative, pictorial level, to students that will enable them to understand, and when necessary, refute, arguments given by those who proclaim that science explains everything.

I’ve made every effort to avoid complex mathematics and have tried to give explanations that are pictorial, qualitative and down to earth. According to beta-readings of chapters by my wife (who’s a math-phobe), former students, and privileged viewers of my blog, this effort has been successful.

I’ve tried to relate specific areas of Catholic teaching with the appropriate science basics, as shown in the Table of contents. Finally I have tried to show how science, by its very nature, is limited in what it can tell us about the world. It has achieved much to enrich us materially, but as that great philosopher-physicist, Fr. Stanley Jaki, put it so eloquently,

“To answer the question To be, or not to be?’ we cannot turn to a science textbook.”

January 10, 1946: Project Diana

Scientific advances from World War II revolutionized our world and beyond.  Sixty-one years ago the experiment of the United States Army Signal Corps, called Project Diana, in bouncing radar signals off the moon bore fruit.  Radar took 2.5 seconds to make the round trip of almost half a million miles.  Thus radar astronomy, along with the United States space program, was born.  Careful calculations had to be made each day to account for the Doppler effect.  Moonbounce radio communication is still used by some amateur radio operators.

E. King Stodola, the scientist who served as the technical director for the project, recalled it in 1979 during an interview conducted by his daughter, Cindy Stodola Pomerleau: Continue Reading
