The Pleasure of Finding Things Out

This is the phrase that celebrity physicist Richard Feynman used to describe the joy of scientific research. But it also describes the joy of science education. Feynman was as brilliant of a scientist as you could hope to meet, and to him mathematical equations were as obvious as the nose on your face. But he knew very well that science education did not consist of learning piles of facts. He knew it was a matter of joy: professors and students alike should share this joy. This is what I always tried to do as a science educator, even to the extent of trying out what some colleagues thought of as stunts.

This is the reason that Bill Nye the Science Guy is more popular among people in general than any professor could hope to be. Professors try to impress their colleagues; but Bill Nye’s audience is ordinary intelligent people.

Jamy Gormaud is France’s answer to Bill Nye. He started off as a reporter, then discovered the joy of science—just as Carl Zimmer and David Quammen started off as fiction writers and found their calling in science writing. Today, with his YouTube channel, Jamy uses humor—a lot of it—to communicate not only science but also history to a large audience. My wife and I started watching his videos in order to learn French, by slowing down the videos and reading subtitles. But I appreciate his joy of science. In one of his books (Mon Tour de France: Des Curiosités Naturelles et Scientifiques) he has assembled a tour of France to see scientific curiosities. Several dozen videos later, he is still one of our favorite video hosts. Jamy describes the pleasure of learning new things as “la connaissance qui soulève l’esprit” (knowledge that lifts the spirit). He practices “la vulgarisation de la science.” Vulgarization is not a bad word in French, although American professors and writers hate to be accused of vulgarization. It just means making science understandable and interesting to non-specialists.

He takes his readers to old places to see new things. He starts his book in the marshlands of northeastern France mainly because he saw some great sunrises there when he was a kid. This chapter is about why sunrises (and sunsets) are red. Maybe you know why, and maybe you don’t. My answer was mostly right.

Sunlight is intensely white, which results from the mixture of all visible wavelengths of light. But when sunlight encounters atmosphere, it scatters. Blue wavelenths, at one end of the spectrum, scatter more than the others, which is why the sky around the noontime sun on a clear day is blue and the sunlight itself is yellowish: the sunlight is white minus some of the blue color. When sunlight has to travel through more of the atmosphere, as when it comes in at an angle at sunrise or sunset, not only do the blue wavelengths scatter but also the others, except those at the red end of the spectrum. If you did not know this, you might have felt your brain grow a little bit right then. Thanks to Jamy, and maybe to some outstanding science teacher you may have had in the past.

Jamy, and other good science educators, also draws in perspectives from outside of science. It was Isaac Newton who explained that white light is all the rainbow colors mixed together. We do not perceive it as a range of colors, but as bands of color. It turns out, for reasons I explain in my book Scientifically Thinking, that our brains create the illusion of bands of color, which helps our brains make sense of the world. But, Jamy wondered, why did Newton say there were seven bands of color? Clearly there are bands, but can you really see seven bands? Violet, indigo, blue, green, yellow, orange, and red. Long before Newton, Robert Boyle had written that a rainbow has five bands of color. Jamy explained in his book that Newton was very religious—he wrote more pages about religion than about science—and to him seven had great Biblical significance. That is, Newton had a little bit of religious illusion even in his hard scientific observations.

He must be very satisfied in his work. To the extent that my videos fulfill the same role as his, I am satisfied. Even though I have retired, I continue to be a science educator, in the tradition of Jamy Gourmaud.

How Religion "Advances"

Today it is relatively rare to find racist Christianity. As indicated in the previous essay, there is still plenty of it. But nowadays, fundamentalist megachurches proclaim that members of any race are equally invited to donate money to their coffers. But it wasn’t so long ago that many white fundamentalist Christian groups did not want to associate with members of other races.

It is even rarer to find Christians who insist that the Earth is the center of the universe. The only example of which I know is the Fixed Earth website. But it was not very far in the past that churches all insisted on geocentrism as a fundamental belief.

In these and in many other cases, the advances in belief—advances toward racial harmony and a scientific understanding of the universe—were the result of forces and processes that were not inherently religious. After slavery was abolished, people began to gradually realize that people of other races were fully human and deserved the same rights as one’s own race. Partly this was due to the utter failure of supremacists to find scientific verification for their beliefs, but mainly, I believe, because more and more people became acquainted with members of other races and discovered, usually pleasantly, that people they might once have disdained were actually nice, ordinary people. In many cases it was devout people who led the push toward racial harmony—and there is hardly a better example than Martin Luther King Jr.—but it was not religion itself that led these advances. None of the leaders, or followers, of racial integration re-read their Bibles and discovered, “Holy Moley! Right there is a verse that we’ve been overlooking for two thousand years.” The Bible did not change. There were, or so the fundamentalists claim, no new revelations from God. The advances in racial harmony, inside and outside of churches, came from accumulated experience which most religious groups have now acknowledged. Reason and experience led the way; religion followed.

It is clear that the conversion of religious people to heliocentrism occurred because science advanced, and religion followed.

Science, experience, and reason are the head of the animal of society; religion is the tail, sometimes wagging, sometimes dragging.

Homage to Abélard

At the Notre Dame Cathedral in Paris on July 23, the lines were very long just to get through security inspections and enter inside. This was only to be expected, since it was a Saturday during tourist season, and was also a response to the nearly daily terrorist attacks, such as a few days earlier (July 14) in Nice, and more recent ones in Germany. But I had already seen enough ornate cathedral decorations (see an earlier essay about the Strasbourg cathedral, also called Notre Dame). What I wanted to see and experience inside was something that was probably either off limits at the best of times, or maybe locations now lost to the historical record.

I wanted to see the chamber in which Peter Abélard lived in the twelfth century, and the classroom in which he taught.

Abélard was most famous for being the 35-year-old monk who had a torrid love affair with the 19-year-old nun Heloïse, in revenge for which her Uncle Fulbert arranged to have Abélard castrated. But Abélard was also one of the planet’s major scholars of his time, and Heloïse was an accomplished scholar herself.

And the thing that made Abélard different from all the other scholars was that his primary rule, first, last, and always, was to question what we think we know and what the authorities have told us. His famous quote, preserved in various forms, was this:  “The beginning of wisdom is found in doubting; by doubting we come to the question, and by seeking we may come upon the truth.” This was the closest that any scholar had yet come to the scientific method.

Abélard’s world was extremely limited compared to ours today. He could not have imagined the vastness of the universe, or even that Earth was just a planet like the others that revolved around the sun. He could not have imagined Copernicus, much less Darwin. To him, the universe was as orderly as an astrolabe, the little device that calculated the time and the phases of the moon and the positions of the planets based upon a geocentric model. He and Heloïse even named their love child Astrolabius! But he stretched his mind as far as anyone could at the time.

So I satisfied myself with seeing Notre Dame de Paris from the outside. It was splendid, as the photos show, but not as significant as the contribution that Abélard made to the history of scientific thought.

What is Hell Like? Come to Church and Find Out, or Not

I think this is the third time I have posted photos on this blog from the marquee of the church down the street from where I live. In the first photo, the marquee indicated, “Big Bang Theory: You’ve Got to be Kidding—God.” Interesting that God should actually provide a direct quotation to this particular church without providing it to other churches. I kind of thought they believed the Bible was God’s word, but apparently God sends them direct quotes. I used this photo in my 2012 book Life of Earth: Portrait of a Beautiful, Middle-Aged,Stressed-Out World. At first I thought God was ridiculing cosmology, but I have gradually come to realize that what really disturbed God was the television series by that name. Apparently God really hates TV shows with geeks in them. In the second photo, the marquee announced, “Evolution: The Science of Calling God a Liar.” I made a YouTube video of this sign, and it got copied around the FaceBookosphere.

Note of caution: There is a website that makes fake church marquee images. They are funny but don’t take them seriously. For example, the church sign that said, “God to President Bush: Those little voices are not from me. Check your meds,” was funny but not genuine. And that joke about the church marquee that said, “What is Hell? Come to church and find out” is likewise apocryphal.

But in this third example the marquee looks, at first, not too different from other church marquees. It is not outrageous, but subtly misleading in a way that I think is interesting enough to discuss at this point. There is a website called “ExploreGod.” In their videos, being shown at this church, they ask important questions, such as Does God exist? or (as in this photo) Why does God allow pain and suffering? These are good questions. But how a church approaches them and how scientists might approach them reveal a fundamental difference between religion and science.

First note that science itself cannot answer either question. But scientists as people frequently wonder about such questions and come up with personal answers to them.

When a church asks, Does God exist?, there is only one possible answer. And everything that leads up to their conclusion is forced into lockstep march toward that conclusion: the answer of Yes. But when scientists ask, Does God exist?, you get a whole range of answers. Science does not force its arguments into a lockstep march toward the answer of No. Many scientists answer Yes, many answer No. But many scientists, myself included, cannot answer this question. Instead we ask, what do you mean by God? If you mean a supreme being who controls all the details of the universe, the answer is clearly No. But if you mean a spiritual essence of love, the presence whereof can never be tested but which many of us would really, really like to believe in, the answer is a resounding I hope so for those of us in the middle. Scientists are always questioning our assumptions and biases. The churches answer the question like an army; scientists answer it like a herd of cats.

Similarly, when churches ask the question in the photo, you know that they will reach some kind of answer or other that leaves God both merciful and all-powerful. They might answer it (especially this church), “God allows suffering because there are Democrats in the world.” Others might answer it, “Because God is testing and strengthening us.” But both of these answers fail to match the evidence, because (in response to the first) even Republicans suffer now and again—there are some forms of pain from which even assault weapons cannot protect them—and (in response to the second) because pain and suffering is way, way, prodigiously, lugubriously, supercalifragalisticexpialadociously, abominably greater than is necessary for strengthening a person’s character. We all expect life to be challenging, to find thorns in a rose garden, but for many people (so far, not for me) suffering has been overwhelming. A little Palestinian kid getting killed by an Israeli mortar, or getting killed because she was used as a human shield by an Islamist terrorist, does not promote that kid’s spiritual development. (See, here is common ground between Israel and Hamas: they both believe that Palestinian civilians are expendable.)

The one answer a church will not permit is to say, “Shit happens and God doesn’t stop it.” There may be a God-essence that wants us to overcome struggles to the extent that we can, and this can be considered a potential Christian answer, but no church would say this, because then people would stop coming and bringing their money. That is, if you can’t get God to alleviate your suffering, then what is the point of prayer and church involvement?

But scientists as people are open to a range of responses to such a question.

As Bart Ehrman has pointed out in his book God’s Problem, the Bible offers about four different answers to the question of why God permits suffering, depending on which part of the Bible you read. The answers all contradict one another. Scientists, as people, would note this range of Biblical answers without trying to force everyone to believe just one of them, without screwing the scriptures that say otherwise into confirming the belief decided in advance.

And of course there are lots of religious answers outside of Christianity. Christian Scientists (who are not Christian scientists) claim that suffering is an illusion.

Conservative religion says, “We have the answer, and we will force all evidence, even scriptural evidence, into confirming it.” Scientists as people say, “There are different possible answers, and we may just have to accept the fact that we cannot know which if any are correct.”

In closing, I point out that this photo was taken on September 22, 2014. Notice that the sign is still advertising a God-loves-guns-and-wants-you-to-have-assault-weapons seminar they sponsored the previous May. The seminar is over enough already and you should take the sign down. But they don’t, because this sign—apparently a permanent fixture now—expresses that they think the Gospel is really about: not Jesus, not God, but guns.
