On Nov. 5, former Wesleyan Professor of Physics Walter Guyton Cady (1874–1974) was celebrated during a virtual program sponsored by Wesleyan and the Institute of Electrical and Electronics Engineers (IEEE) Ultrasonics, Ferroelectrics, and Frequency Control Society. Cady, who earned his PhD in physics in 1900, taught at Wesleyan from 1902 to 1946 and founded the Wesleyan Radio Club in 1914.

Cady's principal interests included electrical discharges in gases, piezoelectricity, ultrasound, piezoelectric resonators and oscillators, and crystal devices. In 1921, he developed the first piezoelectric quartz crystal oscillator, which advanced ultrasonics, sonar, radar and other electronic applications. They appeared in everyday life through their use in quartz wristwatches.

Janice Naegle, dean of the Natural Sciences and Mathematics Division and Alan Dachs Professor of Science, spoke on “Cady’s Groundbreaking Work on Piezoelectricity.” “A quartz, under pressure, produces an electric current; or conversely, sending a current through the crystal causes the crystal to vibrate,” Naegele said. “And Cady discovered that when the frequency of an oscillating current is applied to the crystal and varied, the crystal responds vigorously. In other words, it resonates with a single frequency and could be used, therefore, as an oscillator to stabilize circuits.”

C. Stewart Gillmor, professor emeritus of history and science spoke on "Resonance and Renaissance: The Work of Walter Cady and Physics at Wesleyan, 1900-1940s."

C. Stewart Gillmor, professor emeritus of history and science, spoke on “Resonance and Renaissance: The Work of Walter Cady and Physics at Wesleyan, 1900–1940s.” Gillmor explained that while Cady was in high school, he hoped to become an electrical engineer, however, after two years at Brown University he decided to become a physicist. “But Cady also was a Renaissance man and contributed to early plasma physics, ergonomics, sonar and general acoustics, radio antennas, measurement standards, physiological optics, and bird studies.”

Ahmad Safari, Distinguished Professor of Materials Science and Engineering at Rutgers University, presented the event's keynote lecture on "Advances in Development and Applications of Piezoelectric Materials."

Students Discuss Politics at Pre-Election Fireside Chat

On Nov. 2, more than 65 students gathered at one of four locations on campus for a pre-election fireside chat and s’mores.

“The event provided students an opportunity to socialize under the stars, meet new people, and showcased the compassionate and empathic community that Wesleyan can be,” said Rabbi David Leipziger Teva, University Jewish Chaplain and director of religious and spiritual life.

The event was sponsored by the Office of Religious and Spiritual Life (ORSL) and several student leaders from different campus communities.

“Fire is a place for warmth, survival, and renewal. We’re living in tumultuous times; join a caring community of your fellow students to find solace around the fire,” said Emily McEvoy ’22, the religious and spiritual diversity intern at ORSL.

Andrea Roberts, associate professor of the practice in chemistry; Anthony Hatch, associate professor of science in society; and Jennifer D’Andrea, director of counseling and psychological services (CAPS) co-facilitated dialogue at the fireside chats along with a student leader.

“A great time was had all around,” Roberts said. “Laughter, the voicing of serious concerns, singing, talks of the future and the election and classes and the holidays. Everyone was so grateful, especially me for the opportunity to be a part of it!”

Rouse Leads Faculty Fall Luncheon Talk on Radical Naturalism

Joe Rouse, the Hedding Professor of Moral Science in the Philosophy Department and the Science in Society Program delivered a faculty fall luncheon talk Oct. 21 on "Radical Naturalism: A Philosophical Research Program."

Joe Rouse, the Hedding Professor of Moral Science, delivered a faculty fall luncheon talk Oct. 21 on “Radical Naturalism: A Philosophical Research Program.” Rouse has taught in Wesleyan’s Philosophy Department and Science in Society Program since 1981.

Rouse's primary research interests are in the philosophy of science, the history of 20th C. philosophy, and interdisciplinary science studies. Within these areas his primary foci include the philosophy of scientific practice; naturalism and anti-naturalism in 20th Century philosophy;

Rouse’s primary research interests are in the philosophy of science, the history of 20th-century philosophy, and interdisciplinary science studies. The sciences, Rouse explained, need no longer “defer to philosophy for their conceptual grounding. On the contrary, a broadly scientific conception of the world provides the horizons for contemporary philosophy,” he said.

In this talk, Rouse how he strives to situate scientific understanding in scientific practice.  "The experimental and observational systems and the practices and skills that the sciences develop are not just a means to scientific knowledge to which then stands on it own. They are integral to scientific understanding."

Theater Department Performs Socially-Distanced Fall Show, SLABBER

The Theater Department presented its fall show, SLABBER, Oct. 16–18 on the Center for the Arts green. The socially-distanced performances were open for groups of 48 audience members at a time.

Directed by Assistant Professor of Theater Katie Pearl, SLABBER introduced the audience to a group of enigmatic figures who have traveled to Wesleyan to diagnose their mysterious condition—one they have been suffering from for years. As they reveal their research, audience members are pulled deep into a fable of an outcast little girl, the history of Middletown, and a soap-cutting machine known only as the slabber.

This performance asked the Wesleyan community to consider notions of social and physical contamination, and whether it’s possible to come close to someone else without ever leaving your chair. Originally created by the interdisciplinary theater duo PearlDamour, the work was re-devised by the Wesleyan Student Ensemble, Here and Now, for the current socio-political moment.

“The pandemic is impacting kids in different ways,
 especially kids of color and Black kids,” Tejada said. “And how do we think about our grading and our assessment during this
 time? And that shouldn’t be just during a pandemic, right?
 That should be happening all the time.
 And my hope is that we’re going to be holding onto some of those
 changes that we’re making right now and thinking about how those are
 making our schools better places regardless.”

Five years ago this December, Jacob Scherr, an international environmental attorney, lit up the Eiffel Tower to mark the start of the “Climate Revolution” with the signing of the historic Paris Climate Agreement. Since then, the signs of a changing climate have become more evident, and calls for action, particularly from young people, have grown louder in spite of the Trump Administration’s determination to withdraw the U.S. from its international leadership on this existential threat. Scherr shared his decades-long first-hand perspective of where we are today in the U.S. and worldwide in dealing with the climate crisis. “I feel confident that we’ve indeed built a strong global architecture that can stimulate transformative climate action worldwide once there’s the political will,” he said. “I hope that I can return to Wesleyan for my 55th reunion in person, and I hope all of us can celebrate, then, the accelerating climate revolution.”

PhD Candidate Drum Discusses Biology Research during Graduate Speaker Series

Drum

Zachary Drum, a PhD candidate in biology, delivered the first 2020–21 Graduate Speaker Series talk on Oct. 2 through Zoom. Drum’s advisor is Joseph Coolon, assistant professor of biology. The Coolon Lab uses genetic and genomic tools to better understand how insects evolve to form a resistance to pesticides, damaging $10 billion in crops annually.

Zachary Drum, a PhD candidate in biology, delivered the first 2020-21 Graduate Speaker Series talk on Oct. 2 through Zoom. Titled "The Forbidden Fruit: How Drosophila sechellia came to Love Morinda citrifolia," Drum's research explores how a fruit fly species in Africa is able to eat a poisonous fruit that flies in the the rest of the world would find toxic.

Titled “The Forbidden Fruit: How Drosophila sechellia came to Love Morinda citrifolia,” Drum’s research explores how a fruit fly species in Seychelles is able to eat a poisonous fruit (noni) that flies in the rest of the world would find toxic. Ripe noni fruit contains the fatty acid volatiles octanoic acid and hexanoic acid, which are poisonous to other Drosophila species. “The host fruit has these chemicals that they [sechellia] like, and other flies don’t. They’re attracted and resistant to the fatty acid volatiles in the noni fruit,” Drum explained. “So we’re trying to build this puzzle. How does it resist these volatiles?” (Slide show photo by Charlotte Freeland)

Jewish Community Celebrates Journey to the Holy Land in WesSukkah

sukkah

During the first week of October, Wesleyan’s Jewish community constructed its annual WesSukkah on the McKelvey Green. During the festival of Sukkot, held Oct. 2–9, 2020, students use the dwelling for socializing, meditating, eating meals, studying, and occasionally sleeping. The eight-day celebration is generally observed by Jews, although students from any faith or background are allowed to enter and use the sukkah.

During Sukkot, the Jewish community celebrates the Israelites’ 40-year journey to the Holy Land, which concludes with the celebration of Hoshana Rabbah. Although sukkah walls can be constructed from any material, Rabbinic building code suggests that the roof must be built from organic material. The WesSukkah’s roof is made of bamboo.
