Under the Temple This amazing structure has risen beautifully out of the ashes of the Provo Tabernacle. The developing Provo City Center Temple has kept much of the original structure and design. These details were provided in part by BYU’s Department of Geological Sciences as well as Emily Utt and Benjamin Pykles, historic site curators in the Church History Department of The Church of Jesus Christ of Latter-day Saints. Together, they investigated the site to explore possibilities and to predict problems that could arise while building the new temple. In the process, they discovered that there had once been an older tabernacle near the Provo Tabernacle.

students for bright futures. Two such students are chemistry graduate students Debolina Chatterjee and Danielle Mansfield (p. 11). They work with Dr. Adam Woolley and recently developed a “lab on a chip” which uses just a drop of urine to test for diseases, a test that can be done at home instead of the doctor’s office. Along with Woolley, Chatterjee and Mansfield co-authored the study for the journal Analytical Methods. We express thanks to all who support us and help the college continue to grow. We are grateful for the efforts of our faculty and staff. We are also appreciative of so many of you who support the college in numerous ways. As we have mentioned before, the financial support many of you have provided to the college has made a real difference in opportunities our students have to develop innovations in math and science. With your continued support, we will move forward and give growing students the opportunity to develop the next revolutionary advance. We hope you will catch the vision of what our students can do and get involved in supporting the future. See how our college endowments are growing on p. 9. Wishing you all the best,

MEMORY BYTES In this issue’s Memory Byte, alumna Rebecca Carlson shares an experiment she did.

Up to Our Knees in Physics By Rebecca J. Carlson (Physics and Astronomy, BS’95, Laie, Hawaii)

In the fall of 1992, my Physics 221 teacher assigned each class member to come up with an original project based on some topic in the course. I decided to measure the flow rate of the water jets in the old Talmage building fountain (which is no longer there) so I could calculate the water pressure in the pipes. I collected a three-gallon BYU Creamery bucket and a tape measure. Then I borrowed an orange traffic cone from Campus Security, taped up the small end, and had the cone carefully weighed in the physics department stock room. On a chilly night, one of my classmates and I rolled up our jeans and waded into the Talmage building fountain. Using my HP 48 calculator as a stopwatch, I timed how long it took each of the small side jets to fill my bucket. Then my friend and I splashed into the middle of the fountain, balanced the taped-up traffic cone on the large center jet, and measured how high the water lifted it. Of course we were soaked in the process. We had a long, cold, wet walk back to Heritage Halls, but we got the data I needed.

ALUMNI SPOTLIGHT

A CS ROCK STAR Text: Mackenzie Brown

Striding proudly among the students playing his trumpet in his daughter’s marching band, David Jackman (BS ’94, MS ’02) does not seem like the typical BYU computer science alumnus. Jackman, who played in the jazz band Synthesis at BYU back in the early ’90s, has volunteered in his daughter’s marching band classes and currently helps out his local junior and high schools’ jazz bands. “My oldest daughter would complain that I was more popular at her school than she was,” Jackman laughed. However, Jackman has a lot more to offer the local schools than just his musical talent. Jackman is a software engineer for Microsoft and is involved in the Microsoft sponsored Technology Education And Literacy in Schools (TEALS) program. He currently teaches the Intro to Computer Science class at Orem and Timpanogos high schools in addition to his day job.

David Jackman uses his computer science degree to give back by teaching kids how to code.

Jackman and two other local computer scientists, Larry Fluckiger (BS ’88) and Tyler Castaldo (BS ’12 BYU-I), donate their morning hours teaching computer programming classes in Utah Valley’s high schools. This service furthers TEALS’s initiative, which focuses on getting computer science classes in as many high schools as possible. TEALS provides curriculum for computer science professionals from various companies to teach computer science classes at high schools all over the nation. “I want to have a class where at the end of class the students can actually write a program on their own,” Jackman said. “No matter what careers you go into, knowing how to program a computer can be very, very valuable.” The students seem to understand the value of the class as well. Jackman started out in 2012 with a small class of eight students. This year, he had twenty-five students in that same class. The students’ increasing interest is beneficial not only to the students but also to the software industry. It is estimated that 150,000 computer science jobs open up every year all over the nation. In 2010, fewer than 40,000 American students received a degree in computer science. Currently in Utah, only 25 percent of high schools offer a computer programming class of some sort. Unfortunately, those statistics aren’t much better in other states. Clearly, there is a substantial difference between the supply and demand in the job market (Wingfield, 2012). Jackman believes that getting more computer science professionals involved in high schools could help more students graduate with degrees and fill the computer science job openings. “The idea is to help people in the industry realize they really can do this—they can provide this service to the high schools to keep programming going,” Jackman said. Whether he’s teaching kids to play instruments or teaching kids how to code, Jackman hopes to get more people to join the band of coders. After all, as William James Adams (also known as will.i.am), a popular singer, once said, “Great coders are today’s rock stars.”


COLLEGE NEWS

New Leadership

Cindy Snow has been appointed as the new CPMS representative to BYU’s Alumni Board. Representatives on the BYU Alumni Board act as voice for both the dean and alumni of each college on campus. In 1971, Snow became one of the first women to earn her bachelor’s degree in computer science from BYU. She has worked at Intel Corporation and as an adjunct faculty member at BYU.

Our college contines to use donated funds to support undergraduate research and keep our graduate programs competitive. With the help of your donations, we can keep progressing toward our goal of $20 million in endowed funds. Nathan Cordner, an undergraduate student in the Department of Mathematics, is one student who has benefited from donations to the endowment. The donations make it possible for Cordner to participate in a mentorship opportunity with Dr. Tyler Jarvis. Together, they research mirror symmetry, an area of mathematics resulting from the theories of high-energy particle physics. “Being able to work with a professor is good because if I get stuck, I can go to someone else and ask questions, get some advice, and then go back to my problem and keep working on it,” Cordner said. “Having experiences outside of the classroom to continue learning and doing research . . . prepares students to be successful as they go on to their careers.” Cordner’s research experience will give him an edge when he applies to grad school, putting him on the path to accomplishing his goal of a career in academia.

Research: Joshua Anderson and his students

have found a protein switch that could affect the treatment of cancer. The switch would keep cancer cells from eating themselves, which would result in them becoming more chemo-sensitive. This new development has the possibility of lowering doses of chemotherapy.

COMPUTER SCIENCE Research: Eric Ringger visited BYU Radio’s Thinking Aloud to discuss his research in natural language processing, also known as computational linguistics. Although there are still several challenges in the way of computers understanding language perfectly, Ringger said that the possibilities for advances in this research are limitless. Possible uses for devlopments range from linking family history relationships to automatic machine translation from one language to another. GEOLOGICAL SCIENCES Research: The BYU Museum of Paleontology now houses the fossils of a Rhinorex condrupus, an ancient dinosaur with a very large nose. The “Nose King” lived in what is now Utah during the Late Cretaceous Period. Museum curator Rodney Sheetz, along with North Carolina State University’s Terry Gates, recently published a study on the discovery in the Journal of Systematic Paleontology. MATHEMATICS

In Remembrance: Donald Robinson passed

away in his home on November 10, 2014. Robinson taught mathematics at BYU from 1956–1998, and his tenure included a period as the Department of Mathematics chair. After he retired, he created an endowment fund that provides scholarships to mathematics students. Robinson also served on the college’s volunteer leadership council (CVLC), and participated in several community activities.

Research: Denise Stephens was interviewed

on BYU Radio’s The Morning Show to talk about her research efforts in finding another inhabitable planet in space. Stephens discussed the Kepler and TESS missions, which measured star brightness in order to identify planet candidates.

STATISTICS Research: Dennis Tolley and retired historian Mel Bashore published a paper on pioneer mortality in BYU Studies. They discovered that, surprisingly, pioneer mortality rates are quite consistent with general mortality rates during that time period. Death rates were much higher for pioneers traveling by handcart than for those who traveled by wagon. Research: Scott Grimshaw and Scott J.

Burnwell of Fox 13 News created a model that predicts which NFL team matchups would generate the largest TV audience. Their findings show that in addition to watching their favorite team, viewers also watch whoever is winning, making the bandwagon teams the second-favorite team.


STUDENT NEWS

OUTSIDE OF THE CLASSROOM Chemistry & Biochemistry Graduate students Debolina Chatterjee and Danielle Mansfield, along with professor Adam Woolley, have developed a “lab on a chip” device that would allow users to test themselves for disease at home. The device is a tiny test tube that is lined with specific DNA sequences. When a drop of urine is placed in the tube, the DNA sequences grab on to any disease markers and slow down the flow in the tube. Results are almost instant, so users can avoid long waits, both in doctor’s offices and after doctors’ visits waiting for lab results. They also won’t have to worry about getting their blood drawn. This diseasedetection method also has the potential to be more accurate than more traditional methods; the DNA sequences will not stop innocent material that is similar to disease markers. So far the device can detect markers for kidney disease and prostate cancer, but the same idea and practice can be used to develop tests for other diseases.

Undergraduate student Allyson Derocher works with professors Blake Peterson and Keith Leatham on a National Science Foundation-funded MOST (Mathematical Opportunities in Student Thinking) project. MOSTs are moments in a classroom where student mathematical thinking could be used productively to develop mathematical concepts. The identification of these moments will assist teachers as they work with students to develop critical thinking skills.

“My [desire to learn about the earth] was more basic. Basic exploration: to see what no person has seen before; to be the first.”

14 FRONTIERS

It’s empty. That’s what Dr. John McBride immediately thought as he stepped onto one of the grassy expanses in the midwestern state of Illinois. To onlookers, the miles and miles of flat land with no exposed rock formations would seem like a strange place for a geologist to go. But by using oil industry seismic exploration data, McBride was able to create images of the earth’s crust and mantle tens and tens of miles beneath the surface— into the unknown. Not to be limited to one geophysical technique, McBride has also used ground-penetrating radar (GPR) equipment to map the buried remnants of an early Mormon settlement in Nauvoo. Experiences like this display a basic human sentiment: pursuing the thrill of discovery. This is a philosophy that McBride, chair of the Department of Geological Sciences, ascribes to wholeheartedly. “I think [my interest in geology] started out simple: [I’d ask,] ‘What’s down there?’ McBride said. “My [desire to learn about the earth] was more basic. Basic exploration: to see what no person has seen before; to be the first.” That interest led McBride to thirty-five years of working in geology, both in the petroleum business with Amoco International and Shell Offshore and in academic settings at Cornell University, University of Cambridge, the University of Illinois, and BYU. McBride joined the BYU faculty in 2002. Though he doesn’t get out of the office as much as

he used to since becoming the department chair, McBride still satisfies his thirst for exploration by working with students and faculty on field geophysics projects as time permits. “I use various types of geophysical techniques to remotely sense what’s in the earth beneath us,” McBride said. “For example, I use echo sounding, or sound waves, to generate an image of what the earth looks like with seismic methods. More recently I have adapted GPR methods to study a variety of problems, including Mormon archaeology and scattering of electromagnetic energy in glacial ice.” The geophysical technology and software that McBride uses was pioneered by petroleum companies, who use the technology to explore for oil deposits. McBride uses this earth-scanning technology to search for things in the earth such as mineral deposits, geologic faults, and targets for CO2 sequestration. McBride has used the technology everywhere from the Bahamas to Italy to the Czech Republic, but one of his favorite experiences of discovery occurred in the Midwest. “For geologists, the Midwest can be the worst place possible to work,” McBride said. “There is often little to see on the ground surface, so you depend on geophysical tools to see beneath the surface. One of my favorite moments of discovery was using deep-penetrating sound waves to detect the geological structure beneath Illinois. I was able to see down several tens of miles and discovered that there is a huge amount of interesting geology deep below the cornfields. One feature I found was evidence of a rift zone like our own Utah Valley on the edge of the Basin and Range, buried under the miles and miles of dirt and rock.” McBride and his team of students have also put their subsurface-rendering skills to use by helping The Church of Jesus Christ of Latter-day Saints improve their archeological efforts in several areas, such as exploring the site of the Provo City Tabernacle (now the Prove City Center Temple site) in Provo, Utah, looking for evidence of the location of Haun’s Mill in Missouri, and peering beneath the city of Nauvoo, Illinois. “If you look at old photographs, in the nineteenth century Nauvoo was covered with houses and had maybe 12,000 people living there,” McBride said. “We know where [the people] went, but what did they leave behind?” McBride and his team have walked the radar equipment up and down Nauvoo in order to produce images by sending electromagnetic waves (“light”) into the ground. The team has discovered and mapped foundations of homes, walls, and cisterns in three dimensions, all buried underneath the dirt, gravel, and clay that now blanket the Nauvoo of the 1840s. “The efficiency of how light penetrates matter depends on the frequency of the waves,” McBride said. “Analogous to sound, low-frequency or ‘bass’ signals will penetrate deeper than the ‘treble.’ Just like sound, if light waves are a lower frequency, they can penetrate deeper . . . You have an interface between, say, a bunch of soil and a buried foundation made out of some kind of rock. The rock produces a reflection, or echo, of light back to the GPR equipment. You can use this echo effect to map the subsurface.”

McBride is grateful to have the opportunity to serve the Church and the community with these geophysical techniques. “(My team and I] are useful in ways that are not just science-, technology-, or economics-related, but in ways that relate to that which is sacred,” McBride said. McBride also has the opportunity to serve others through teaching. He loves his job and research, but aside from that, the people that truly keep McBride coming back to work every day are the students. “What really motivates me is working with the students,” McBride said. “I really enjoy taking them to these different places, to see how they respond to the new kinds of environments, and to see their sort of ‘aha!’ moments; it’s just kind of a vicarious enjoyment.” When McBride worked in the industry in the early 1980s, he couldn’t help but feel as if he were in a rut. When he left the industry and started teaching, he realized that the students wouldn’t let him get back into the rut—not then, not ever. Every day held a new challenge; every student had a new question. “As a professor, you have the privilege of being part of [the students’ learning] process,” McBride said. “Right here, you are right on the edge of learning—the edge of the unknown. You aren’t out there by yourself; you’re with these students who you see go through this transition from just wanting to learn to now wanting to work with and lead others. That’s a great experience.”

r. Wayne Barrett keeps a list of retirement plans tucked safely in his front pocket so he can continually add to it as he thinks of new ideas. “I realize I won’t be able to do everything on my list, but I can do a lot more than before!” he said. Barrett retired last September from the Department of Mathematics after a thirty-nine year career as a teacher, researcher, and mathematician, but he did not retire as a mentor. At the top of his retirement list are his students, whom he continues to advise, even after formal retirement. Barrett learned to love mathematics at a young age from good teachers who made problem-solving fun. Since then, he has always had a knack for working on puzzles and solving difficult problems. “I like that a lot of the time mathematics problems have unexpected solutions,” he said. By the time Barrett began college, he knew he wanted to study mathematics. The influence of good teachers also instilled in Barrett a desire to use his knowledge to become a mentor for other mathematicians, a theme he has carried throughout his career. Barrett earned a bachelor’s degree in mathematics from the University of Utah in 1968 and a PhD from the Courant Institute of Mathematical Sciences at New York University in 1975. He taught at both the University of Wisconsin– Madison and Texas A&M before applying for a position in the BYU Department of Mathematics in 1981. “As I watched the Holiday Bowl with my family the preceding December, I said, ‘If BYU wins, then we will get the job,’” Barrett joked. “This was the famous Miracle Bowl where BYU barely won when Jim McMahon threw a Hail Mary pass in the final seconds of the game, which was caught by Clay Brown.” Luckily, BYU won and Barrett was hired as an associate professor in the BYU Department of Mathematics. For four decades, Barrett has dedicated his career to helping his students learn to love math as much as he

does. In his thirty-three years at BYU, Barrett has been happy to spend significant time mentoring undergraduate student research. “I always say I do everything for free except grading papers,” Barrett joked. Barrett puts high emphasis on helping his students get involved in research early in their undergraduate careers so they will be as prepared as possible for the demands of graduate school. He has never regretted dedicating much of his time to mentoring his undergraduate students. “I used to think helping an undergraduate do research was just going to be a drain on my own research and that it would be so hard to get them up to speed. But I think I just didn’t know the right kinds of problems for them to work on. I’ve gotten a lot better at that,” he said. “You can do so much more with students. . . . It’s great to work with people who make contributions you weren’t even expecting.” Barrett has found that his students are often especially helpful when it comes to incorporating technology into his research. He also enjoys seeing them become mentors to each other as they collaborate and use each other as resources in their own projects. His passion for helping others does not go unappreciated. Nine of Barrett’s past graduate students attended his retirement dinner last year, where a student secretary presented him with a photo album commemorating his time at BYU. Many of Barrett’s past students have stayed in contact with him over the years, and several have continued to collaborate with him in their own research. As a teacher, Barrett was dedicated to helping struggling students, but he especially enjoyed having the opportunity to work with the gifted students who really had a desire to understand mathematics. “One of the best parts of being a teacher,” Barrett said, “is seeing your students experience the thrill of mathematical discovery.”

CRITICAL THINKING: FROM MUSIC TO MATTER WAVE INTERFEROMETRY Text: Jennifer Johnson Photo: Scott Daly

t’s not often that a music major ends up as a research physicist for the Air Force Research Laboratories, but that is what happened to Christopher Erickson. Growing up, Erickson was involved in a broad range of activities. In high school, his activities extended from athletics to theater productions. He credits an outstanding high school physics teacher with helping him to recognize an interest in science. Erickson entered BYU as a music major for performance on string bass. However, when he returned from serving an LDS mission to Argentina, he declared physics as a major as well. Pursuing a double major in college seems daunting, and Erickson said he wasn’t sure about it at first, either. “Part of that is that I don’t have a really good grasp on reality so I don’t tend to know what my limits are,” he said. Originally, he planned to leverage his physics training in a music career, but as he progressed in the major he realized that he loved science, too. He eventually got involved as a research assistant in Professor Dallin Durfee’s lab studying atom interferometry. As a result of that work, Erickson stayed at BYU to earn master’s and doctoral degrees. In graduate school, he applied for many fellowships before receiving a SMART fellowship with the United States Department of Defense. Through this fellowship, Erickson was offered the position he now holds at Kirtland Air Force Base in New Mexico. His research there is in matter-wave interferometry; that is, using the quantum waves associated with atoms to make measurements. The two lab’s primary focuses are developing atomic clocks for space and navigation devices for GPS-denied environments. Erickson acknowledges both the coincidental experiences and the raw perseverance that led him to where he is today.

“There were three distinct times where I about walked out [of graduate school]. I was going to stop. . . . It wasn’t worth it. It’s worth it now,” he said, laughing. “[I felt that] a doctorate degree [could be] a tool to really keep my options open. . . . The only way to not pigeonhole myself into something was to pursue a degree that I could apply in just about any field that interested me. And physics is one of those things that you can do that with.” Erickson was able to apply his physics degree during a presentation he gave at the TEDx event in Albuquerque, New Mexico in 2013. “That was fun,” he said. “That was surprising, actually. Somebody at work sent around the call for speakers, and I thought, ‘Well, you know, doing this kind of research is very interesting, and a lot of people don’t know about it.’ I figured that would be something of interest. . . . To my surprise, they were much, much, much more excited about that topic than I would have guessed.” He said he is also grateful for the unexpected experience of staying at BYU for all three degrees. “It wasn’t until I was a graduate student that I really learned to appreciate BYU, that I really learned to appreciate what a unique institution it is, and really, what an opportunity it is to go to school here,” Erickson said. That appreciation drew Erickson back to BYU in October 2014 to give back to the College of Physical and Mathematical Sciences. He performed demonstrations and delivered a presentation to students about the options that come from studies in the hard sciences. “[I have] the career that I’ve always wanted,” Erickson said. “And it’s because twelve years ago as an undergraduate I went over to the physics department to bring something back into the world of music.”

ome fathers and sons bond over woodshop projects or fishing trips, but father and son BYU professors Gerald Watt and Richard Watt have always bonded, instead, over chemical reactions. “I remember after my first year in college . . . when I went home at Christmastime, my dad had a reaction going in the lab, so we went into the lab to finish it,” Richard said. “We went into his office to start talking about science and then about three hours later, my mom called and said, ‘Are you guys okay?’ Science has been a real strong bond that we both liked. It’s a hobby that we do together.” Richard has always had the perfect mentor in his father, whose life and career was shaped by his experience at BYU as a student. Gerald’s first impression of his professors was what inspired him to become a teacher himself. “BYU was just this awesome place. It was huge compared to where I was raised,” Gerald said. “I started taking some chemistry classes, and I was really impressed with the faculty. They were so genuine and concerned about people learning, and it was . . . those types of experiences that made me want to do the same thing: to be a professor.” After a twenty-year career at a private research lab in Ohio, Gerald returned to BYU in the winter of 1990 as a professor to teach what he loves, and the experience was “all [he] expected and more.” For about sixteen years, Gerald taught in the chemistry department. Richard never had his father as a professor, but he has still learned from his father’s example, and his decision to become a professor himself was heavily motivated by Gerald’s influence. “A huge influence in my life was seeing his example and seeing what he did, how he did it, and how much he enjoyed

it,” Richard said. “He’ll say that he’s never gone to work a day in his life because he comes in and he plays every day.” Gerald retired in 2006, but he and Richard still interact regularly at BYU. They love to get together and talk about their shared interest. Even when Richard lived in different parts of the country for school and work, the two constantly collaborated on projects and ideas. At family gatherings, they find themselves getting lost in scientific chatter. One of Richard’s favorite memories of his dad was when Gerald was awarded the American Chemical Society award in Utah for developing a bio-nanobattery. “He talked about all of the different steps that were involved in doing that and taking it to completion and making it work,” Richard said. “That was one moment where I could see the beauty of time mixed in with all the chemistry.” For many years, Gerald has been Richard’s example and inspiration, and now Gerald finds himself learning from his son. “Somehow he got some really good genes. . . . You go through life as a father and you teach, but now I think the tables have been turned. I’m learning a huge amount from him. It’s this progression that has slowly evolved, and now I’m the student,” Gerald said.

Gerald is particularly grateful to have a son who can help him out with the latest technology. “The real advantage is that even though I am from a digitally handicapped generation (I can’t even set my watch), I [can] come to him.” Gerald has loved to see Richard progress over the course of his career and his life. He remembers when Richard was just a child. “When he was a boy, he could do a Rubik’s Cube like you wouldn’t believe,” he said. “In fact, one morning I caught him in bed trying to do his Rubik’s Cube with his feet.” Now one of Richard’s greatest accomplishments, in Gerald’s opinion, has been his ability to synthesize information. “He has put something together scientifically that is a gigantic Rubik’s cube,” Gerald said. “He’s working on a cohesive model now, and it could have a huge impact on treating a number of different diseases. The greatest [accomplishment] is seeing him do things that I couldn’t do.” Currently, Richard and Gerald are working together on a project that turns biomass (lawn clippings, corn, leaves, etc.) into electricity. Though it was never their plan, the project is a new way for them to grow and learn together as father and son.

L

et’s begin with a story, shall we? In the middle of the thirteenth century, a Dominican friar named Thomas Aquinas was instrumental in laying the foundation of accepted cosmology for centuries to come. Several of his writings became so widely used in the schools of the so-called scholastics, that for centuries, even until today, they became a standard part of the theological curriculum. Aquinas’s ideas became so entrenched that they took on a special status: dogma. Now, let me clarify up front. For our purposes here, I make a distinction between dogma spelled with a small letter “d”— meaning in a broader and more informed sense—and dogma spelled with a capital “D”—meaning specific points of belief as proclaimed by some churches that followers must adhere to. Dogma is essentially a belief, which in one’s mind is so well established that it may not be questioned even in the light of overwhelming evidence to the contrary. Because this can be an impediment to finding truth, I’ve entitled my presentation, “The Dogma Trap.” Anyway, back to our story. Aquinas is given much credit for his efforts to harmonize revealed religious truth and the understanding of truth according to reason. Like many today, myself included, he took the position that faith and reason are both legitimate sources of truth, and that they can and must mutually conform to the same truth. He made the argument that the study of nature and the application of reason were equally valid to revelation in finding the nature of God and his creations. Thirteen centuries earlier, Aristotle had laid out a model of the universe based on observation and reason. The earth was at the center of the universe—the central focus of God’s creations—and the sun and the moon orbited around it in circles. Aquinas adopted this model, with the perfect, unchangeable heavens in concentric spheres, home of the various ranks of angels. And finally we encounter the outermost realm, where God resides. The harmonizing of science and religion in this way was a great strengthener of faith for Christians and remained so for hundreds of years. Of course you recognize that this isn’t the model we use. The switch to a sun-centered solar system was not easy for people of the fifteenth century. Imagine being in their shoes: it would surely be unsettling to you that men such as Copernicus, Kepler, and Galileo were promoting a new sun-centered model with heavenly bodies that are not perfect homes for angels. In their minds, the Aristotelian model of the cosmos had become more than a good idea; thanks in part to Aquinas, it had become entrenched to the point of being unquestionable. In other words, dogma. In the end, scientists, sooner, and religionists, later, both came to accept the transition to a new model of the universe. Yet, we shouldn’t take for granted that this has always been so. For many, it was a long, agonizing slog to make this transition. And dogmatic thinking was the primary slogifying influence, if you’ll permit me to invent that term. This story illustrates how the confluence of science and

religion provides the perfect opportunity for exposing dogmatic views. So, given that the Summerhays lectures focus on the relationship between science and religion, I’ve chosen to address how dogmatism can be an impediment to progress in both areas of pursuit. I’d like to focus my remarks on three theses: first, science and religion are both built on faith; second, belief systems in both arenas embrace specific articles of faith, both formal and information; and third, belief areas in both arenas are susceptible to dogma traps, which impede their pursuit of truth. Of course, the pursuit of truth is central to the missions of both science and religion. Indeed, they share at least one common goal, which may be summarized as follows: to help us understand the world we live in, cope with it, control it, view our proper place in it and achieve the greatest possible personal fulfillment in it. As to thesis number one, there is certainly nothing new about asserting that both science and religion are grounded in faith. In the realm of religion, reference to faith goes almost without saying. But the principle applies equally to science. Let me illustrate. In science class when you studied the structure of the atom or the Krebs cycle in living systems, did you not take it on faith that the instructor wasn’t just making all that stuff up? Yes, of course you did; you took it on faith. The only way science can advance is if every successive generation has faith in the claims of the careful observation and analyses and recordings of its predecessors. Consider this: the high priest of atheism, the biologist Richard Dawkins, may bear his testimony that there is no God because you cannot observe Him scientifically. He may say, “How can you believe in God? Have you seen him?” The religionist might answer, “How can you believe in electrons, have you seen one?” He may say, “No, but I have seen their effects reproducibly in the laboratory.” The religionist may answer, in the same way, “I have seen the effects of God in my life and the lives of others.” In both cases, the proponent has faith that he sees the effects—the one of God, the other of the electron—deduces the existence, and has faith that his conclusion is a correct one. Furthermore, in both cases the proponent relies on faith in the testimony of witnesses, those who have more direct experience than he or she does. The religionist strengthens his faith in the testimony of prophets who have seen or had close experiences of the divine. The scientist has faith in the testimony of predecessor scientists, who have performed and recorded the results of their experiments. One important difference is that in science, reproducibility is the basis for faith, and in religion, faith-promoting events are rare, and not predictable, and therefore, not reproducible in the scientific sense, but that doesn’t mean they aren’t real. Nonetheless, reproducibility is a widely accepted principle in science. It goes without saying, and some might treat it as dogma, insisting that it be applied to test all hypotheses in all arenas.

But first, let’s move onto my second thesis: belief systems in both areas, science and religion, embrace specific articles of faith, both formal and informal. Many religions post formal statements or articles of faith. Mormons have thirteen, the National Baptist Convention has eighteen, and so on. For religious believers, these points follow very close to or on the dogma end of most people’s certainty spectrum. Science also has its articles of faith, or “self-evident truths”, though they are seldom discussed. These include existence, causality, position symmetry, time symmetry, non-contradiction, and finally, Occam’s Razor, among others. As is true with the articles of faith in many religions, most scientists hold these ideas to be near or on the dogma end of the certainty spectrum. More often, troubles arise with some of what we might call the “lesser” articles of faith. Now what do I mean by

PHOTO: Scott Daly

Now, every belief that is held to be dogma is not false or bad. If dogmatism is a problem, the problem is not with the belief itself, but with the holder of the belief. I called reproducibility a fundamental principle of science. Scientists apply it almost religiously to our practice. It’s a good principle. But like any good principle, it becomes problematic when it becomes an unquestionable principle, that is, you are not allowed to question or modify it under any circumstance. At that point, it becomes dogma in your mind. I envision in each person’s mind, a certainty spectrum, ranging from “I really don’t know and I probably don’t care” on one extreme and dogma on the other. It is at the extreme endpoint that we may cross the subtle border between close to unquestionable to completely unquestionable—that is, dogma. That’s where we become trapped. I’ll return to this idea in a few minutes with some examples.

these “lesser articles”? Well, people, scientist or religionist, have been taught or have developed in their own minds, a certain set of beliefs or understandings, which perhaps when first encountered, found themselves somewhere in the middle of the certainty spectrum, but which over time have been repeated so often, challenged so seldom, become so comfortable, that they have gradually and inexorably crept along the certainty spectrum toward the dogma end. Without even realizing it, the person has become dogmatic about that particular idea. And this is where we often run into trouble. This leads me to my third thesis. That is, belief systems in both arenas are susceptible to dogma traps that impede the pursuit of truth. Examples abound of instances where dogma has impeded human advancement. I invite you to contemplate the consequences of dogma for yourself. First, the idea that the black race is inferior and those who are part

of that race are natural slaves. Second, that the bible story of the creation took exactly six 24-hour days. Third, that eugenics as practiced by the Nazis is a true science, and its principles demand that the strong remove the weak from the gene pool. And I imagine you can think of a lot more. I hope in this short time I’ve convinced you that keeping an open mind is the best path to seeking truth and making progress. Dogmatic thinking by contrast is a trap. Let’s follow the example of Joseph Smith and be open and creative in our thinking as he expressed in our 13th Article of Faith, amenable to what the Lord has to offer us, and avoiding unyielding dogma.

Your Donations Can Help Pioneer New Discoveries When Dr. Dennis Tolley introduced Corinne Saltzman, an undergraduate student studying statistics, to the pioneer mortality rates research group, she was fascinated. What they found surprised her: pioneer mortality rates were not much higher than the average mortality rates of that time. “The purpose of the study is to try and find exact figures for the death rates of pioneers crossing the plains to show a complete picture of how many and which kinds of saints were most likely to die on the trek,” Saltzman said. “[The] findings [the research group] had weren’t the usual takeaways from pioneer stories. Pioneer stories make it seem that the death toll was a lot higher, but we found that the overall pioneer mortality rate was lower than previously thought.” This research opportunity put Saltzman on the path to achieve her goal of working in health care statistics.

My mentorship was a real world, practical way to use the skills I learned in my classes. Having an internship and experience is crucial to finding an actual job in this field.” We invite you to help BYU students participate in similar pioneering opportunities in research.
