A Frontiers in Science Lecture to celebrate 2019, the International Year of the Periodic Table
Why do atoms behave the way they do? Why do electrons form “shells,” as seen in the periodic table?
Why does the first shell hold 2 electrons, the second 8, and the third 18: twice the square numbers 1, 4, and 9?
It took many years to solve these mysteries, and a lot of detective work in chemistry, physics, and ultimately – once the relevant laws of physics were known – mathematics.
Other mysteries remain unsolved, like the mass of the heaviest possible element. This talk will give a quick tour of these puzzles and some of the answers.
About the Speaker
John Baez is a professor of mathematics at the University of California, Riverside, who also works at the Centre for Quantum Technologies, in Singapore. His Internet column “This Week’s Finds” dates back to 1993 and is sometimes called the world’s first blog.

The School of Earth and Atmospheric Sciences Presents Dr. Peter Webster: Emeritus Professor, GA Tech
Global Climate Synergies and Synchronization:A Potential Vorticity Substance Perspective
For decades, it has been thought that the tropics and the extratropics were relatively independent. If there was a connection it was thought, incorrectly, to be through some form of a zonally symmetric Hadley Circulation. Further, the two hemispheres, vastly different in geography, one mainly ocean, the other with a far greater landmass, have been assumed to be relatively independent. Yet, total annual rainfall rate or volume in each hemisphere is the same within 2%.
The annually averaged top of the atmosphere radiation budget is also nearly identical. Reponses to asymmetric forcing (one hemisphere greater than another) appears to produce a near-identical interhemispheric response. The question then becomes how can this synchronization take place? Is there an overriding physical constraint?
It evolves that these global structures can be best understood in terms of the conservation of potential vorticity substance that is conserved even in the presence of diabatic heating and dissipation (as distinct from potential vorticity that may not be conserved). This understanding allows the “impermeability theorem” of Haynes and McIntyre (1987) to a wide range of problems such as: the communication between the extratropics and the tropics, communication of signals between hemispheres and the synchronization of the response.
The possible relevance of these ideas to dynamic meteorology, climate dynamics and climate change (including paleoclimate), and perhaps planetary atmospheres, will be discussed.
This work comes from joint research with Drs. V. Toma and S. Ortega.
To celebrate 2019 as the International Year of the Periodic Table, the College of Sciences and the Georgia Tech Office of the Arts have partnered to infuse the 2019 Clough Art Crawl with the spirit of the periodic table.
The annual Art Crawl serves as a unique opportunity for Georgia Tech students to showcase their artistic talents. The theme for the Spring 2019 exhibition is Art Meets Science. In conjunction with Georgia Tech's year-long celebration of the International Year of the Periodic Table of the Chemical Elements, a special section of the Spring exhibition will be devoted to art inspired by the periodic table or a chemical element.
The Art Crawl features art from all students in the following categories:
Visual Art – drawings, paintings, and photography
Digital Art – code-based art, animation, film, and graphic design
Structural Art – sculpture, architecture, crafts, and textiles
Literary Works – poetry/prose, comics, and short stories
Performance Art – dance, live instrumentation, vocal performance, music production, and theater
The exhibit will open on March 14, 2019, at 4 PM. The Art Crawl will award prizes to winners in each category. In addition, College of Sciences will present awards for the top submissions in the special section on the periodic table. Winners will be announced on March 25, 2019.
The visual, digital, structural, and literary art works wil be exhibited through July 31, 2019 at Clough Commons.
The following is from the article By Cassidy Villeneuve on March 1, 2019
It’s not every day that a student takes the time to officially thank their professor for a great project. But that’s what Dr. Jennifer Glass’ student at Georgia Institute of Technology did after learning how to write Wikipedia articles as a class assignment. The thank you came in the form of a certificate of appreciation issued through Georgia Tech’s Center for Teaching and Learning. In conjunction with the certificate, the student wrote:
Dear Dr. Glass, Thank you for being such an enthusiastic teacher throughout the year, and for challenging our class to go out of our comfort zones with the Wikipedia project. I thoroughly enjoyed each lesson as well as the project, and I am so excited for EAS [Earth and atmospheric science] classes to come. Have a wonderful break!
The evolution of complex life is an inherently multidisciplinary problem encompassing a wide range of topics, including:
- How do new levels of the biological hierarchy evolve?
- How do interactions between individual organisms contribute to complex phenotypes and behaviors?
- How do social behaviors evolve?
- How do evolutionary novelties emerge and evolve?
- How do organisms drive geochemical cycles and how do geochemical changes influence evolution?
This conference brings together scientists from different backgrounds to discuss these and other important topics about one of the most salient aspects of life: the evolution of complexity.

What is earthquake “music”? Can coral reefs devastated by climate change be saved? Does science support the supposed benefits of meditation?
ScienceMatters, the podcast of the College of Sciences, brings more tales of curiosity and discovery. Season 2 is now live at sciencematters.gatech.edu.
All episodes are available for instant listening. However, the ScienceMatters quizzes will follow the episode order. Follow the College of Sciences on Facebook and Twitter (@GT_Sciences, #sciencematters) to find quiz questions and meet winners.
Stars of Season 2
Season 2 features five of the College of Sciences’ award-winning faculty and one of its enterprising postdoctoral researchers.
- When the Earth’s tectonic plates collide and slide, School of Earth and Atmospheric Sciences Professor Zhigang Peng takes data from seismic sensors and creates “earthquake music.” The results can help scientists learn more about what goes on beneath our planet’s crust.
- There’s more to meditation than just chanting mantras in your favorite yoga studio. Practitioners claim the benefits include better mental and physical health. Do the data back those claims? School of Psychology Professor Paul Verhaeghen examines the science behind meditation.
- Glaucoma usually affects older people, but a form of the eye disease can strike younger patients, including children. That keeps School of Chemistry and Biochemistry Professor Raquel Lieberman hard at work studying wayward proteins that may hold the key to new treatments for the second-leading cause of blindness.
- One of the top algae scientists in the world, award-winning School of Biological Sciences Professor Mark Hay, examines the mortal peril facing the world’s coral reefs in a two-part episode. The first part gives a grim prognosis. But the second part offers hope that the coral reefs could heal themselves – if given the chance.
- With incessant curiosity, David Hu discovers physics among water-walking geckos, bridge-building ant, and urinating zoo animals. Hu, an associate professor in the School of Biological Sciences and the School of Physics, has a joint appointment with the George W. Woodruff School of Mechanical Engineering. This conversation is an edited excerpt from the Uncommon Engineer podcast. Our thanks to Steven McLaughlin, podcast host and dean of the College of Engineering.
- Kennda Lynch studies ancient lakes on Earth that serve as stand-ins for Mars’ formerly flooded craters. The School of Earth and Atmospheric Sciences postdoctoral researcher helps NASA look for potential landing sites on the Red Planet.

The monthly series "My Favorite Element" part of Georgia Tech's celebration of 2019 as the International Year of the Periodic Table of Chemical Elements, #IYPT2019GT. Each month a member of the Georgia Tech community will share his/her favorite element via video.
Amit Reddi is an assistant professor in the School of Chemistry and Biochemistry. He is an inorganic chemist interested in the roles metals play in biology. Up to 50% of all proteins require a metal for their proper functioning. Yet, only about a dozen metals are encounterered in biology.
That so few metals allow proteins to function in hundreds of different ways is what drew Reddi to research: to better understand how proteins and metals interact to achieve diversity in protein function.
On the other hand, the metals crucial to protein function are also toxic to cells when they are not handled properly in the cell. At Georgia Tech, Reddi studies how entire cells and organisms are able to use metals productively fashion, without suffering their toxicity.
His favorite element is .... Watch the video!
