Dr. Gnidovec on Orton Hall | Devon Leahy

The format of this presentation was unique in that it took place in Orton Hall. Beginning with a brief history of the building itself, I thought it was neat that the geological construction of the building corresponded to the order it occurs naturally in Earth. It is also notable that the columns lining the lobby are each made out of different Ohio rocks and minerals.

I like how Dr. Gnidovec dropped names like Thomas Jefferson and Andrew Carnegie during his presentation. Those are names I never would have associated with fossils. It’s funny that Jefferson told settlers to watch out for mastodons and giant sloths following the Louisiana Purchase; extinction still was not commonly accepted, which I think is wild. In the future, I’m hoping people will view not believing in global warming as outlandish as I did when I heard people did not believe in extinction. Of four giant sloth skeletons found in Ohio, Orton houses the best dated one at 13,100 years old. I hope my own enthusiasm towards my future job matches Dr. Gnidovec’s towards paleontology. His passion towards his work my favorite part of the presentation.

Dr. Alber on Louis Pasteur | Devon Leahy

Dr. Alber began her discussion on Louis Pasteur by asking us our thoughts on Pasteur’s most striking characteristic, his greatest accomplishment, and his motivation. To me, his most striking characteristic was his drive. He didn’t need approval from others to keep doing science. His greatest accomplishment was discovering and convincing others that germs cause disease. This was the foundation of the rest of his accomplishments, like anthrax and rabies vaccines and sterilization. His motivation was intrinsic: he didn’t do these experiments for money or fame.

As a microbial physiologist, Pasteur primarily worked alone studying how microbes work. His studies ranged from wine fermentation to human diseases. I liked hearing how Pasteur framed his experiments, as I’ve learned about some of these experiments in prior classes. His novel S flask experiment disproved spontaneous generation, but he kept an open mind to the theory before testing it. Emphasizing the need to control media conditions, he was the first to discover that different microorganisms have different growth condition preferences. I was impressed that he blew his own glass, prepared his own chemicals, and synthesized his own media for experiments.

What sets Pasteur apart from other scientists of this time was how he went on to find practical and applicable solutions to the diseases he studied. I enjoyed Dr. Alber’s presentation, concluding that his work’s greatest accomplishment was finding causative agents and ways to control them. Seeing the Louis Pasteur movie beforehand gave great context and characterization to her presentation.

Dr. Samir Mathur Black Holes | Devon Leahy

Heading into this lecture, I knew very little about black holes and the physics of the universe. I enjoyed learning from Dr. Mathar, who did a fantastic job of explaining the basics behind some incredibly complicated theories. It was refreshing to have a lecturer who used drawings on the chalkboard rather than a PowerPoint to reinforce his points.

Dr. Mathar’s presentation centered around the paradigm shifts occurring on the origin of the universe, stemming from Stephen Hawkings’ contributions of Hawking Radiation (1974) and the Black Hole Information Loss Paradox (1975). These concepts were difficult for me to wrap my head around. The foundation of these theories are black holes, which form when stars shrink to white dwarfs, white dwarfs shrink to neutron stars, and neutron stars eventually collapse to a black hole. However, the mass of the stars does not go away; rather, it all goes to a single point (the black hole). This is known as a singularity, or something that is frustrating because it is not supposed to happen. Hawking Radiation is the energy that should be emitted by a black hole as an object moves closer to the black hole. The Black Hole Information Loss Paradox says that when a particle goes in the black hole, its information is lost forever. There is negative energy when a particle gets too close to the black hole, and once a particle passes the horizon of the black hole, it can never come back out. After all of this research, we still only know about 5% of visible matter.

According to a diagram that Dr. Mathar drew on the board, the Big Crunch will occur when the universe starts shrinking, acting as the opposite of the Big Bang. After hearing all about black holes, I found it to be a little unsettling that String Theory could prove that nothing about black holes is correct. According to String Theory, nothing can be crushed into a point. Instead, it all expands into a ball. I will be interested to see how this paradigm will shift in my life time.

Dr. Chris Otter Interpreting the History of Science | Devon Leahy

Dr. Otter began his presentation on the interpretation of the history of science by setting up the context in which Thomas Kuhn wrote, “The Structure of Scientific Revolutions”. By emphasizing the shape of history, we can see how history lead to the modern world of scientific thinking. Science was used as a weapon to fight superstition during the Enlightenment, and in the 19th century science was popularized through university, where the science was equated to progress. The 20th century saw lots of texts that argued the scientific revolution was the most important thing to happen in history, one even comparing it to the coming of Christ. The Scientific Revolution can be simplified to the point in which society became dynamic; science became distinguished from pseudoscience; and error distinguished from truth.

I really enjoyed the discussion on limitations of the definition of fact. While we have been trained to accept facts as truth, there is the suggestion that facts are actually an agreement to stop exploring an idea. This implies that society can open any truth and destroy it, since facts are socially produced. An example of this is climate change. American society has just chosen not to accept climate change as a fact yet.

The basis of Kuhn’s work is the idea that science cannot function without paradigms, a set of collective ideas that scientists agree on. Normal science is performing experiments that maintain the current paradigm, sometimes producing evidence that does not fit. While these anomalies are usually ignored or labeled as pseudoscience, an accumulation of anomalies throws existing paradigms into doubt. Paradigm shifts occur when there are enough anomalies to replace an old paradigm, but the shift temporarily splits science into two- those holding on to the older paradigm, and those in favor of the new one. Kuhn notes that during these splits, the answer cannot be found in the natural world because people are seeing the same thing through different lenses. Dr. Otter described the feeling of arguing a new paradigm to those who refuse to see anything but the old way as incommensurable. I liked Dr. Otter’s observation that people who initiate paradigm shifts tend to be young and on the outside, or those who are less consumed with the traditional perspective.

Kuhn disagreed with early historians of science who attempted to linearize science. He concludes that truths just become replaced by other truths which better explain anomalies. New paradigms do not have to explain everything; they just needs to explain more than the prior paradigm. Overall, I was surprised by how much I enjoyed this presentation, and I liked how Dr. Otter mentioned that there is more than truth to paradigms. People are emotionally, socially, and financially connected to them.

Dr. Goldish Science & Religion | Devon Leahy

In all of my science classes prior to this, the role of the church has only been discussed in the context of how it has hindered science. I was intrigued when Dr. Goldish presented the full picture. From the Age of Enlightenment to modern fictional works like Angels and Demons, the intersection of science and theology has been misconstrued. Dr. Goldish began his discussion with Copernicus, a priest in the Catholic church, who performed his research because the Pope was considering a calendar reform. By putting the sun in the center of the solar system, rather than the Earth, Copernicus was able to eliminate these problems. The Catholic church encouraged him to publish this theory, but due to coinciding timing with the split of the church, people were especially sensitive towards new ideas. This could be misinterpreted as the first “rift” between science and religion. Kepler was also deeply religious. He believed he was working with the tools God gave him to translate “divine presence” through mathematical models. His major contribution was theorizing the elliptical orbit. While this did away with God’s perfectly circular orbits, it did reveal the mathematical exactness in nature. It seems like most scientists of this period (Kepler, Galileo, Copernicus, Newton) were religious. This makes sense because the most literate people were often monks and priests.

My favorite part of Dr. Goldish’s lecture was the drama of Galileo. When Galileo, a deeply religious Catholic, proved the Copernican system, the future Pope replied that his math was inferior and God’s logic was different from his. In retaliation, Galileo put the Pope’s side of the argument into the simpleton character of a book he then dedicated to the Pope. Overall, I was happy to hear Dr. Goldish say that the warfare between science and religion does not exist. Most of history actually shows scientific work and religion working together, since both theology and science have always been considered areas of knowledge and wisdom.

Dr. Breitenberger Women in Science| Devon Leahy

As a woman in science, I found this presentation to be extremely relevant. Most of my science classes always mention the men behind historical experiments and theories, so it was refreshing for the women to finally receive some recognition. From Margaret Cavendish being the first woman to be invited to the Royal Society meeting in 1667, all the way to Marie Curie being awarded the first Nobel Prize to a woman in 1903, it is evident that traditional views have excluded women from science. Even women who did manage to overcome this suppression, they rarely did so independently. They all had families or husbands with whom they worked with, such as Caroline Herschel and Marie-Ann Lavoisier. It is frustrating that some women’s work has been misattributed to men. I appreciated how Dr. Breitenberger emphasized these wrongdoings.

English and French women scientists brought a new perspective of science that was often overlooked in the 19th century. Science was thought to be just a collection of facts, but these women demonstrated that mathematical models, and the articulation and translation of science is just as valuable. I like how Dr. Breitenberger included how Marie Curie’s personal life was brought into question for her success in her professional life. That is something we still see today for renowned women. I enjoyed this presentation greatly. It showed how far we have come with the inclusion of women in science, and how far we still have to go.

Dr. Cogan: A Tale of Two Chemists | Devon Leahy

Dr. Cogan’s presentation focused on the work of Joseph Priestley and Antoine Lavoisier towards modern chemistry. Although the two chemists did not work together directly, they came to a similar understanding about oxygen and performed similar experiments to observe the same results. With the help of a French spy, Lavoisier was able to replicate Priestley’s oxygen and mercury experiment. Priestley’s pneumatic trough allowed him to study pure gases; he discovered oxygen by heating mercury with the trough. Lavoisier performed this same experiment, but he also noted the reverse reaction that Priestly never did. Connecting this to Kuhn’s writing on how paradigms are established, Lavoisier was able to build on Priestley’s observation of respiration. Specifically, this is a representation of how early fact-gathering is limited to what is already understood. In Priestley’s case, respiration was too complex for him to understand in the existing paradigm, but Lavoisier was able to better incorporate it.

I enjoyed the activity of stepping back and considering air in its simplest form because it gave me an idea of the knowledge gap those scientists were working in. I had trouble describing it without becoming too scientific. Something that surprised me was how they were able to do hot air balloon rides while understanding so little about air itself.

It was interesting to learn about the difference between English science and French science that were both going on during the Enlightenment period. While the entire period was about better understanding God’s mind, the French approached science with the expectation of results, as their work could be paid for by the King. This limited the work of science to wealthy men who could afford a prestigious education or those who were well connected; so in a way, practicing science in France during the enlightenment was very much based on class. The English created the first Scientific Society to pose problems, collaborate, and expand knowledge. Even though this did not discriminate on class, scientists were not paid well and often needed to be supported in some other way. This inherently favored the upper class.

I liked Dr. Cogan’s commentary about democracy. Democracy and science developed during this time because they have deep-rooted similarities. Both are grounded in the advancement of the meritocracy and experimentation for measurable and observable results. Overall, I feel like this presentation gave me a well-rounded view of the environment in which these two men made great scientific discoveries. Tying political, religious, and social contexts to scientific discoveries is something still relatively new to me, but I am excited to continue to compare  circumstantial relationships to paradigm shifts.

Dr. Root: John Snow and Epidemiology | Devon Leahy

Dr. Root opened her discussion on paradigm shifts in the epidemiological field by telling how John Snow was able to map the cholera outbreak in London, earning him the title of the “Father of Modern Epidemiology.”  During his time, the miasmatists held the prevailing theory that illness was caused by poisonous vapor. Snow helped to change this by believing “animacuoles” in water caused that cholera outbreak. This contributed to the shift towards germ theory. Dr. Root also emphasized an aspect of Snow’s work that gets overlooked: how he calculated numbers and rates of cholera which provided systematic and quantitative evidence. He also tied geography to demographic and social context of those who contracted cholera. This relates to Dr. Root, as her research focuses on novel applications of geography to fields such as epidemiology.

I was very interested in Dr. Root’s research on vaccine efficacy. Utilizing GIS technology to examine the effects of locational and ecological differences on vaccine efficacy estimates led her team to a small-scale paradigm shift towards geographically randomized vaccine trials. This impacts the design and interpretation of all vaccine studies, and brings environmental, social, and structural factors into consideration. I also enjoyed learning about the emerging field of landscape genetics and how spatial variation in genetics could imply ways landscape affect evolution. As someone with career goals in the public health, I greatly valued Dr. Root sharing her presentation with us, demonstrating the intersection of geography and health.

Dr. Anelli: Darwin and Evolution | Devon Leahy

While Charles Darwin is remembered for his imposing theory of evolution, Darwin’s methodology of hypothetico-deductive reasoning has greatly influenced the evolution of science itself. Dr. Anelli also noted that his studies are not solely limited to the field of evolutionary biology; Darwinian theory is interdisciplinary and has led to Nobel Prizes in fields such as Physiology and Medicine as recent as 2017.

The film Creation helped contextualize Darwin’s life, and Dr. Anelli emphasized this. Life was very different in Victorian England. This presented a range of obstacles that scientists today usually need not consider. Before his work was published, he was quoted that writing about natural selection and descent with modification was like, “confessing a murder.” This stuck for me for two reasons: Darwin knew that he was on the brink of something revolutionary, and it made me consider what scientific discovery today could imitate the culpability of murder, as Darwin felt. His ideas were threatening towards the existing hierarchy and typological thinking of the times. Additionally, Creation helped me understand the internal conflict Darwin felt as he grappled with religion and the external conflict within his marriage to first cousin, Emma, and the death of his oldest daughter, Annie. I found that delving into Darwin’s personal life was refreshing because in science, it is easy to focus on one’s achievements without recognition of overcoming personal struggles.

Dr. Anelli’s explanation of the Paradigm of Natural Theology stood out to me as what could have been most difficult for Darwin to overcome. Reverend William Paley, a man Darwin admired, used the analogy of a watch to relate to creation. All pieces of the watch serve a purpose; nothing is accidental or imperfect. Likewise, Paley believed all species are fixed and constant, perfectly adapted as is. Darwin’s notion that species evolve for better survival had serious implications against the church that God’s creatures could be considered imperfect.

Overall, Creation and Dr. Anelli’s presentation helped create a well-rounded image of Charles Darwin at the intersection of science and history. I enjoyed Dr. Anelli’s point that a good scientist is always asking the why behind the way things are. Darwin exemplified this and how skepticism and patience paired with years of observances can lead to lasting paradigm shifts.
