  • The Science of Why We Love Music

    Why do patterns of sound have so much power over us, stirring our emotions, evoking memories, and leaving a permanent impact on us? Music has been an integral part of human culture for centuries, from the bards of ancient civilization to modern pop artists, serving as a universal language. Human beings have an inherent capacity for music appreciation and enjoyment which is ingrained in our cultural and biological makeup. While speech primarily serves as a means of communication, music serves a different purpose, allowing us to express and experience emotions, moods, and affective states that enhance our quality of life.

    When we hear music, our brains start processing the sound right away. The auditory perception system is like our brain’s “music analyzer.” It breaks down the music into different components, like pitch, rhythm, and melody. This happens in several areas of the brain, including the brainstem, thalamus, and auditory cortex. For example, when you listen to a piece of music, your brainstem picks up the vibrations in the air created by the sound. These vibrations are then sent to the auditory cortex, where they’re decoded into recognizable sounds and patterns. This process allows us to distinguish between different notes, chords, and rhythms in the music we hear.Moreover, our brains can detect subtle changes in pitch and timing, which are essential for understanding melodies and rhythms. This ability to process and analyze sound is crucial for our enjoyment of music because it helps us make sense of the patterns and structures within the music.

    But it’s not just about understanding the music as our brains also try to predict what’s coming next. This predictive ability is crucial for making sense of the music and anticipating how it will unfold. Think of it like predicting the next plot twist in a movie based on the clues you’ve picked up along the way. Our brains are constantly making predictions about the music we’re listening to based on patterns and expectations formed from our past experiences. This predictive process helps us anticipate how the music will progress and allows us to stay engaged with the music as it unfolds. For example, if you’re listening to a familiar song, your brain might anticipate the next verse or chorus based on the patterns established earlier in the song. This predictive ability is what keeps us engaged with the music and makes it feel satisfying when our predictions are correct.

    Now, why does music make us feel so good? When we listen to music that we enjoy, our brains release chemicals like dopamine, which are associated with pleasure and reward. This happens in a part of the brain called the reward system, which is responsible for reinforcing behaviors that are beneficial to our survival and well-being. When our brains detect that the music we’re listening to is pleasurable, they release dopamine, which makes us feel good. This is why listening to music can be such a joyful experience – it literally makes our brains happy! Moreover, studies have shown that our brains respond more strongly to music that exceeds our expectations or surprises us in some way. Our brains are essentially saying, “Wow, that was even better than I thought – I love it!” This heightened response in the reward system is what makes certain pieces of music feel especially satisfying and enjoyable.

    So, when we listen to music, our brains go through a complex process of perception, prediction, and reward. The auditory perception system helps us understand the music, the prediction system helps us anticipate how it will unfold, and the reward system makes us feel good when we hear something we enjoy.

    Understanding these processes can help us appreciate why music has such a powerful effect on our emotions and well-being. It’s not just about the sounds we hear – it’s about how our brains interpret and respond to those sounds, creating feelings of happiness and enjoyment. So, the next time you find yourself lost in your favorite song, remember that it’s not just music – it’s a symphony of brain activity bringing you joy and pleasure.

  • Medieval Medicinal Remedies Not to Try at Home

    In the medieval era, medicinal practices were influenced by a blend of herbalism, superstition, and early medical theories. This led to an array of home remedies, some effective, some strange, some which should never be practiced today, that people of that time used to cure themselves of their ailments. Here’s a list of the most common remedies of that time.

    For migraines

    The medieval remedy for migraines was boiling barley with herbs like betony and vervain, then wrapping them in a cloth and applying them to the head. Betony, a grassland herb, was commonly used in medieval remedies for various ailments and is still utilized in modern medicine for treating severe headaches and migraines. Vervain, known for its glycoside derivatives, was also used in the remedy and is still applied today in modern treatments for migraines, depression, and anxiety.

    For a sore throat

    The medieval remedy for quinsy involved a rather gruesome procedure: stuffing a cat with various ingredients like hedgehog grease, bear fat, resins, fenugreek, sage, honeysuckle gum, and wax, then roasting it and using the gathered grease to apply on the patient’s body. This bizarre treatment is just one example of harmful medieval practices that should not be practiced today. 

    For a cough

    The medieval remedy for treating a cough was consuming a mixture of horehound juice and diapenidion, a confection made from barley water, sugar, and egg whites drawn out into threads. Horehound, known for its effectiveness in treating coughs, was combined with diapenidion, which provided a sweet and pleasant taste. Some parts of this remedy are still used today as sugar, a key ingredient in diapenidion, is used in over-the-counter cough remedies for its soothing effects on the chest. 

    For an upset stomach

    To relieve colic caused by trapped wind, medieval medicine prescribed a remedy made from carminatives, cumin and anise, steeped in white wine for three days and nights. After drying for nine days on an ash board, the mixture was powdered and ingested in pottage or as a drink. Alternatively, dill and fennel could be used for the same purpose, similar to modern gripe water formulas. This concoction usually took around 2 weeks to prepare, so patients would likely purchase this remedy from apothecaries.

    For gout

    To treat gout, medieval people would prepare an owl by plucking it, cleaning it, and salting it before placing it in a pot covered with a stone and baking it in an oven until burnt. Once burnt, the owl was pounded with boar’s grease to create a mixture used for anointing the affected area. However, this treatment was likely entirely ineffective and only led to an unfortunate situation for the owl. 

    A stye/bump on the eye

    The remedy for a stye, or a small painful bump, on the eye was done through first pounding either onion or leek and garlic, then mixing them with equal parts of wine and bull’s gall. After letting the mixture stand for nine nights in a brass bowl, it was strained and applied to the eye with a feather at night. This concoction, though initially unappealing in appearance and odor, exhibited potent antibiotic properties due to the antimicrobial components of onion, garlic, and bull’s gall. Additionally, the reaction between the wine and brass bowl produced bactericidal copper salts. Recent research has validated the efficacy of this remedy, prompting further investigation for potential use against antibiotic-resistant infections like MRSA. 

    For burns and scalds

    Medieval medicine recommended using the slime of a live snail to treat burns and scalds, a simple yet effective remedy that reduces blistering and alleviates pain. Recent scientific studies have confirmed that snail slime contains a range of beneficial properties, including antioxidants, antiseptics, anti-inflammatories, and skin-repairing compounds like collagen and elastin. Modern skincare products, known as “Snail Gel,” now utilize these properties for treating minor injuries such as cuts, burns, and scalds.

    For sciatica nerve pain

    Medieval remedies for sciatica or pain caused by the sciatic nerve often included a mixture of ingredients such as the gall of a red ox, water-pepper, cumin, and suet. These ingredients were boiled together to create an ointment-like gruel, which was then applied to the affected area. Additionally, the patient was instructed to apply heat to the hip bone and use hot cloths on the area. Despite the questionable effectiveness of the ingredients, the combination of bed rest and heat treatments may have provided some relief for sciatica symptoms.

  • Astronomy of the Ancient Skies

    The night sky has captured people’s imagination for cultures across the world throughout human history. From the ancient Mesopotamians and Egyptians to the Mayans and Greeks, ancient people used the stars to shape their beliefs, practices, and societies. 

    One such civilization was Mesopotamia, where the night sky held great mysteries for the ancient inhabitants of Sumer, Babylon, and Assyria. Ancient Mesopotamians studied celestial bodies like the Moon and planets, blending astronomy, astrology, and religion into “astral science.” They developed a lunar calendar around 3000 BCE, with names for celestial entities like the Moongod dating back to 2500 BCE. By 1800–1000 BCE, they named the five visible planets. These celestial bodies were seen as divine manifestations and interpreted as signs from gods. Moreover, Babylonian scholars recorded celestial events to predict future phenomena, introduced zodiac and mathematical astronomy, and developed horoscopy and astrology by the 5th century BCE. 

    Ancient Egyptian astronomy primarily served practical purposes, particularly in time measurement for calendars and daily cycles. The earliest calendar was lunar, synchronized with the star Sirius to align with the natural year. This evolved into a 365-day calendar, divided into three seasons of four 30-day months, with five additional days. The observation of decans rising at nightfall, combined with a 30-day month divided into three 10-day ‘weeks,’ led to the establishment of the 24-hour day. However, the Egyptians also found ways to connect the cosmos to the events of Earth. The Egyptians tracked the movements of stars, particularly Sirius, whose rising was at the same time as the annual flooding of the Nile. This celestial event, known as the “heliacal rising of Sirius,” was believed to lead to agricultural abundance,  and they also built structures like the Great Pyramids of Giza to align with celestial phenomena.

    In Mesoamerica, the ancient Mayans had a similar sophisticated astronomical tradition. Mayan astronomers developed detailed and precise calendars that tracked the movements of celestial bodies through centuries of astronomical observations. Specifically, the Maya Long Count calendar, which spans over 5,000 years, reflects their understanding of astronomical cycles and the way in which they were integrated into Mayan society. Celestial events such as solar eclipses and the equinoxes led to rituals, as they would mark important agricultural cycles and religious ceremonies. Moreover, structures such as Chichen Itza were built for ceremonies in order to align with the movements of the sun and stars.

    In ancient Greece, philosophers and scholars used the night sky as a means to pose fundamental questions about the nature of the universe and humanity’s place within it. Building upon earlier Babylonian and Egyptian astronomical traditions, Greek scholars such as Thales of Miletus, Pythagoras, and Aristotle sought to understand the fundamental nature of the cosmos. One of the fundamental contributions of Greek astronomy was the idea of a geocentric model of the universe, which stated that Earth was at the center of the universe. This idea was famously articulated by Aristotle, who argued that Earth, being the heaviest element, must occupy the central position in the universe. Additionally, Claudius Ptolemy in his work “Almagest,” developed a mathematical model of planetary motion based on a system of nested circles called epicycles which predicted the positions of the planets relative to Earth. Greek astronomers also applied their knowledge of the cosmos to build various instruments, including the astrolabe and armillary sphere, which allowed for precise measurements of celestial positions and movements. 

    Ancient astronomy was some of humanity’s first attempts to decode the universe. The observations and scientific ideas across these diverse civilizations the globe shows the value that humans have placed on this field and the meaning it carries with us. Today, we can continue the legacy of ancient astronomers by continuing to be captivated by the night sky and growing our knowledge of it.

  • Science During the Age of Enlightenment

    The 17th and 18th centuries were a time of profound transformation in Europe in regards to thought, reason, skepticism, and empirical observation. This was nowhere more pronounced than during the Age of Enlightenment, its intellectual and philosophical movements leading to modern democracy, with the ideas ushered in during this time forever changing the scope of Western science. 

    The thinkers of the Enlightenment were inspired to question beyond the limits of scientific reasoning at that time and change human understanding. During the early 17th century, European intellectual reasoning consisted of religious dogma and Aristotelian philosophy, with it being unthinkable to challenge the medieval church’s idea of a divine and static universe that centered around Earth. Therefore, the ensuing Scientific Revolution during this time revolutionized the way that Europeans thought about the world and set a new standard for deductive reasoning and scientific observation. 

    Science at this time was conducted predominantly by scientific societies and academies rather than universities, and while some societies had links to universities, most societies operated on their own. These societies grew to have control over their publications, the election of new members, and the administration of the organization, with there being over 70 different scientific societies by 1789. Additionally, science during this time became more popular among the increasingly literate populace and the public was introduced to various scientific ideas. 

    One thinker who was thought to establish the foundations for the movement was Francis Bacon, who is known for establishing empiricism and the scientific method. His book, Novum Organum, discussed a new approach to gathering knowledge from systematic experimentation, inductive reasoning, and empirical observation. He also wrote about the idea of testing hypotheses through experimentation as a way to pursue scientific inquiry. He was the first advocate for the idea of separating religion from science, and his impact on the science world remains today as the scientific method is still seen as the standard way to approach discoveries. 

    The most pivotal scientific thinker of that age whose legacy remains today is Sir Isaac Newton. His Principia Mathematica described classical mechanics and presented the laws of motion and universal gravitation through mathematical observation and analysis. His law of universal gravitation and the laws of objects in motion changed the way that people practiced science and indicated the need for empirical observation and evidence behind scientific ideas rather than religion. Through this, Newton was able to demonstrate how the same physical laws govern both terrestrial and celestial environments, challenging the ideas of the universe at that time. These insights would also eventually lead to advancements in the fields of physics, astronomy, and engineering.

    Another scientist during this time was Carl Linnaeus, a botanist and physician. His book, Systema Naturae, established the binomial nomenclature for species classification where each species is assigned a two part Latin name for its genus and species. Linnaeus ordered animals and plants into defined groups, such as domains and phyla, and used the scientific ideas of observation and rational analysis to study various evolutionary relationships and biodiversity. His work shaped people’s understanding of nature and created a framework for how botany, zoology, and ecology is studied. 

    Overall, the Age of Enlightenment was an integral part of scientific and intellectual history and changed the way that Europe viewed reason, individualism, and progress. While the Enlightenment might not have explored all modern thought, the scholars, scientists, and thinkers of this time sought to break free from the limited knowledge of their world and seek new truth and ideas. Today, we can reflect on the science from the Enlightenment to continue to make bold scientific discoveries and create our impact on the world.

  • The Discoveries of the Human Genome Project

    Few scientific quests have sought to unravel the essence of what makes us human as the Human Genome Project. The Human Genome Project (HGP) began with the US Department of Energy launching a study to detect genetic mutations about atomic bomb survivors in Japan. Eventually, the National Institute of Health joined, along with a collection of countries across the globe, into what became a public consortium by the Human Genome Organization. HGP officially began in 1990 with a completion goal of 2005, and thus researchers set up to map the scope of homo sapien DNA, the code that determines our traits. 

    Through HGP, scientists uncovered various discoveries about genetics. One such finding was that human DNA isn’t as unique as we originally thought. The genomes of people who are not closely related to each other like siblings or parents are estimated to be different by about 1 in every 1,200 to 1,500 bases. What this means is that if we consider a stretch of DNA having anywhere between 1,200 to 1,500 bases, we would expect to find one difference between the sequences, and this difference could be as small as a single letter change or single nucleotide polymorphism, or as large as differences in the number of copies of certain sections of DNA, also known as the copy number variations. Additionally,  nearly 50% of our DNA is similar to that of other organisms, with more than 40% of our proteins being similar to those of flies and worms.

    Scientists also found out that genes are not evenly spread out across the 24 human chromosomes, and that some regions have many genes clustered together called rich neighborhoods, while others have few genes, known as desert areas. These desert areas consist of 20% of our genetic code, and the other 80% is made up of clustered neighborhoods. Moreover, the human genome has around 20,000 genes for protein building, which is only 2% of our total DNA. This extremely small percentage was the biggest disappointment for the scientists of the HGP, as they had hoped there would be over 100,000 genes in our genome. This discovery challenged the idea that each gene makes only one protein, and eventually led researchers to understand that the complexity of humans isn’t solely determined by the number of genes, but rather by the different ways in which genes code for proteins.

    Today, we can understand that while the Human Genome Project didn’t address all the expectations and ambitions of earlier scientists, it also forever changed the landscape of the study of genetics. Through the HGP, researchers established large databases of genetic data and published to the world the human genome sequence, ensuring that the genome can be accessible at our fingertips. Moreover, in the late 1980s, computers were relatively simple, but by the time the HGP had finished, we had the internet and powerful computers to handle all this genetic data. This led to a new era of digital biology, where scientists and clinicians could analyze vast amounts of genetic information.

    However, with genetic research also comes various ethical implications. One is about who should own and control genetic data – if researchers and healthcare providers should have access to it for genetic studies and patient care, there is also the issue of how ethical it is for companies to commercialize and profit from this data, especially if they sell the information to third parties. Questions around who can patent genes and genetic technologies arose and the impact this can have on genetic research and healthcare. Moreover, with sequencing the entire human genome, there also needs to be safeguards to protect the privacy and confidentiality of the participants’ genetic information from data misuse or unauthorized access. Lastly, there needs to be equitable access to the benefits of genetics research, ensuring that people of marginalized communities are not only participating in the studies, but also receive the advanced healthcare and medicine that emerges from these discoveries. 

    The lessons we’ve learned from the Human Genome Project can guide us to improve our knowledge of genetics and conduct genomic research responsibly and ethically. Moreover, by understanding how our knowledge of the building blocks of humanity have evolved over time, we can develop a greater appreciation for how far science has progressed.

  • Exploring Medieval University Science Education

    Ever wonder what your undergraduate science education would have been like if you attended university during the Middle Ages? 

    We can understand this by exploring the science curriculum of students at Oxford University during the 14th century and how it was shaped by the societal and intellectual context of the time period. For a student studying towards a master of the arts (the equivalent of a science degree), they would need to enter with a strong foundation in the 7 liberal arts, including Boethius’ Arithmetic and Euclid’s geometry, and the 3 natural philosophies such as physics and meteorology. 

    In university, there were two main fields students of science covered: quadrivium and natural philosophy. Quadrivium consisted of the subjects of arithmetic where the students would study number theory and calculations, and geometry for learning shapes, measurements, and Euclidean geometry. They would also learn music, both the mathematical and theoretical aspects, as well as astronomy where they would study celestial objects, the principles behind this motion, and the works of Ptolemy. In natural philosophy, students learned about Aristotle’s works on the natural world, his theories of motion for physics, elements, and celestial bodies, as well as concepts on metaphysics, such as the nature of existence and the structure of reality. 

    These students, as well as others in universities in Paris and other cities, were required to attend lectures on quadrivium and Aristotle, as well as lectures on other scientific topics. Students could sometimes replace the required lectures with these electives – although they wouldn’t receive course credits for them – and there were even university regulations to allow these lectures to continue during holidays in cases of high demand.   

    There were various ways in which the subjects of quadrivium and natural philosophy were at the core of the curriculum for students. In regards to Aristotle’s works, professors would use commentaries from these to explain his complex ideas to students through the lens of their own contributions to the discoveries. Moreover, these commentaries served as both textbooks for students to learn from and research papers for scholarly purposes. Students could study the commentaries to build their understanding on the subject, as well as critique and offer their own ideas to existing ones. 

    Professors also used sophismata, which were logical puzzles or propositions, to allow students to actively engage. Students would participate in disputations, or formal debates and discussions, in order to graduate, where they would defend or refute various propositions. This focus on logical thinking enabled students to form arguments and check for weaknesses or fallacies in their scientific works. 

    Overall, medieval universities had an integrated approach to education where teaching and research were combined. The works that students studied for their science curriculum were also composed of scholarly research content that they could then use to build and refute arguments. While medieval scholars and students were not immune to incorrect scientific theories, they were also limited by the resources and beliefs of that time. By understanding the scientific progress made through the centuries and the way in which education has developed it, we can continue to shape the knowledge of students to come.

  • The Science of Yawning

    We’ve all experienced that urge to open our mouths wide, take a deep breath, and stretch our facial muscles. But why do we yawn, and what explains the phenomenon of contagious yawning?

    Scientifically, yawning is the synchronized motion of the thoracic muscles in the chest, the diaphragm, the larynx in the throat, and the palate in the mouth. This act helps to distribute surfactant, a wetting agent, to cover the alveoli, which are tiny air sacs in the lungs [3]. The brain, particularly the hypothalamus, plays a central role in triggering and regulating yawning. This seemingly simple action, however, sets off a cascade of changes within the body. Yawning increases heart rate, facilitates blood flow, and enhances oxygen intake.

    The precise reason for why we yawn is still researched and debated by doctors and scientists. However, the most common explanations revolve around yawning being used as a way to keep us as alert. Yawning is considered a brain cooling mechanism which leads to an increase in peripheral and cerebral blood flow. The rhythmic contraction and relaxation of facial muscles during a yawn enhance blood flow in the face, leading to the dissipation of heat through emissary veins connecting the surface of the head with the internal blood vessels. Furthermore, the act of gaping the mouth and inhaling cool air during a yawn influences the temperature of the blood traveling from the lungs to the brain through convection [2].

    Another explanation is drowsiness being a common stimulant for yawning, with boredom leading to drowsiness as the primary source of stimulation diminishes. Studies  demonstrate a significant increase in physiological arousal after yawning, shown in increased heart rate and skin conductance levels. This arousal response is likened to the effects observed with caffeine intake, supporting the idea that yawning plays a role in the brain’s arousal reflex. Additionally, the frequency of yawning is noted to be associated with viewing uninteresting stimuli and activities requiring minimal interaction, reinforcing the idea that yawning subserves arousal and higher brain activation [2].

    What is known is that yawning is undeniably contagious, with a single person’s yawn capable of inducing yawning in an entire group. People with higher empathy levels are believed to be more susceptible to yawning in response to others as brain imaging studies have revealed that observing someone yawn activates brain areas associated with social functions. Interestingly enough, this phenomenon extends beyond humans, as dogs also yawn when witnessing their owners or strangers yawn, and similar contagious yawning has been observed in various animals [4].

    Moreover, when members of a group yawn together, it could help align their mental states, making them more synchronized. This synchronization is believed to serve as a form of collective alertness, helping the group become more aware of external threats more rapidly than if each individual were to respond independently. As a result, the spread of yawning in a group is thought to be a way for individuals to share a collective state of readiness and awareness [4].

    Recent research has shed light on the influence of breathing methods and forehead temperature on the contagious nature of yawning. A study exploring these factors found that nasal breathing acted as an antagonist to contagious yawning, significantly reducing its incidence. Participants engaging in other breathing conditions, however, yawned approximately 48% of the time. Moreover, applying a cold pack to the forehead greatly diminishing contagious yawning, while warm and room temperature packs showed no such impact. The combined conditions thought to promote brain cooling, involving nasal breathing and forehead cooling, virtually eliminated contagious yawning, since only one out of 22 participants experienced yawning. These findings highlight the connection between physiological factors, particularly breathing patterns and thermoregulation, and the occurrence of contagious yawning [1].

    As research on the science of yawning advances, we can continue to discover more about this seemingly simple act. So the next time you feel that familiar yawn coming on, remember that you’re engaging in a fascinating scientific phenomenon!

  • The Devil Wears Science Journey

    Working behind the scenes of an event can be an eye-opening experience, especially when it’s a science show with a unique twist. That’s exactly what happened when I had the opportunity to be a part of the Atlanta Science Festival’s The Devil Wears Science fashion science show in March. Since it was my first time working as part of both a science show and fashion show, I was especially eager to be part of such a unique and innovative event. This immersive experience allowed me to gain valuable insights into the inner workings of a successful show, and I was amazed at the amount of hard work, creativity, and attention to detail that goes into putting on such an event.

     

    My group, Too Hot To Handle, focused on discussing and demonstrating the importance of heat stroke prevention through the use of protective clothing, specifically a beekeeping suit, during the event. My teammates were Claudia Ortega and Sachit Swaminathan and in the weeks leading up the show, we worked on reaching out to individuals in the beekeeping community to model and experts in the field of heat stroke prevention to present at the event, and also gathered information about the science behind our topic. 

     

    Prior to the event, I had very minimal knowledge about beekeeping suits, particularly as it relates to heat stroke prevention, so it was quite fascinating to do research and learn more about it. While there aren’t a large amount of scholarly resources on the topic, I tried to understand the different parts and materials of beekeeping suits and then did research on each fabric in relation to heat resistance. Moreover, ​​as I delved into the topic, I realized how much thought and consideration goes into selecting the right materials and design elements for gear such as beekeeping suits, especially since the consequences of inadequate protection could be severe. 

     

    There were some challenges my team and I faced during the planning of the event, particularly in regards to contacting people to discuss the science behind heat resistant gear. Initially, we planned for experts to discuss wearable heat sensor devices and then relate that to the design of heat resistant fabric in beekeeping suits, but we faced some difficulties in finding available experts to participate. After further attempts to contact other experts in the field, we decided to present the science portion of the presentation ourselves and focused on gathering research on the topic. 

     

    In addition to my work behind the scenes, I also had the opportunity to challenge myself and grow in my presentation skills. As the day of the festival approached, I decided to join Sachit in presenting the science portion of the event, which was a significant step out of my comfort zone. I conducted more research to develop a scientifically accurate script, and we kept making edits between the slideshow and script to allow the content to align. I was slightly behind at times due to preparing for a conference I had to attend later that week, but I was determined to gather all the necessary information and be confident in my speaking parts.

     

    On the day of the science fashion show, I was nervous as I arrived at the Kendeda building in my blazer clutching my freshly printed script.  Since there was some time to spare before the show began, I decided to use the opportunity to practice rehearsing for the presentation with my other teammates. This not only helped me to feel more confident and prepared, but it also allowed us to fine-tune the script and the visuals of our presentation, ensuring that everything was in sync and aligned with the overall vision of the show. As the presentation drew near, we gathered with our new models and went over the directions for modeling the beekeeping suits. Despite the initial setback of our previous model not being able to attend, we worked together and found a solution, and as we worked out other technical issues that arose, my confidence grew, and I became more and more assured in my part of the event.

     

    As our team took the stage and our presentation began, I couldn’t help but feel a sense of excitement mixed with a hint of nervousness. However, the more I spoke, the more my confidence grew and before I knew it, our part was over. The feeling of accomplishment and satisfaction was truly indescribable, and it was amazing to see all our hard work finally come to fruition. 

     

    But the night didn’t end there. As the other teams took the stage, the energy in the room continued to grow. I was captivated by the creativity and passion that each team brought to their presentations and it was incredible to see the range of scientific topics and the level of detail that went into each one. 

     

    Overall, I came away from this experience with a greater appreciation for the intersection of science and fashion, and the power of collaboration to bring together different perspectives and talents. It was an amazing opportunity to learn and grow and I look forward to participating in future events that combine my love of STEM and creativity.

     

  • Reflections on Attending a Computer Science Education Conference

    Attending the Special Interest Group on Computer Science Education (SIGCSE) Conference in Toronto in March was truly an eye-opening experience for me. As a student research assistant in the Bridge-Up STEM program, I had the privilege of presenting my work at the conference and gained a new perspective on university-level education.

    I attended the conference from March 15-March 18 with Georgia Tech researchers and researchers from the National Center for Women and Information Technology (NCWIT). The Bridge-Up STEM program, a collaborative effort between GT and NCWT, equips women and non-binary people to do computing research under the mentorship of a College of Computing professor while also mentoring high school students. I specifically attended the conference to present about my work as a teaching assistant to a cohort of local high schoolers who had a research fellowship through the program.

    During the conference, I had the opportunity to understand the various aspects of planning a computer science education at the university level, as well as reflect on my own experience doing so for a high school audience.

    In particular, I realized the importance of the way in which community resources are offered to younger students seeking a foundation in computer science. The panel discussion with other researchers highlighted the challenges of selecting the most suitable students for a research fellowship program aimed at students from marginalized backgrounds. While selecting only straight-A students might exclude those who are interested but haven’t discovered computer science activities yet, identifying students who don’t know much about computer science but have the potential and interest to learn can be challenging during the selection process. Such challenges encouraged me to think outside the box and come up with innovative solutions to better serve students and increase accessibility to computer science education.

    Moreover, attending workshops and panels during the conference hosted by other educators allowed me to have a deeper understanding of university-level computer science education from a professor’s perspective. One panel discussion that particularly caught my attention was on the “5 things not to do when teaching.” One of the mistakes which was discussed by a Harvard professor involved their computing college’s initiative to reinvent office hours for computer science undergraduate students.

    The new initiative replaced the previous format, which featured rows of desktop computers in the basement, with long dining hall tables, and created a new software program that allowed students to ask TAs for homework help. However, this initiative ultimately did not succeed as planned, as most students waited until the last two days of the weekly assignment’s deadline to come to office hours, and when the software for TA waiting times became overloaded, the students had to raise their hands, and there weren’t enough tables for everyone.

    The panel audience mainly consisted of university professors who shared their experiences with implementing various office hours initiatives. However, there was still a gap between the initiatives implemented by professors and the actual learning experiences of the students. This realization prompted me to reflect on my own experience with office hours for different computer science classes. As a student, I have often experienced the issue of an unbalanced TA-to-student ratio, the resulting frustration, and the difficulties that arise when trying to complete my work.

    Thinking about different ways to solve this problem, while taking into account both the student’s perspective and the logistics of professors and educators, I realized that one solution could be to have students write down their question next to their name when they come to office hours, allowing students with similar questions to sit next to each other and help each other out. TAs could also rotate every five minutes, giving each student a chance to ask their question and reducing the overall wait time. Additionally, when a TA helps a student with a particular question, all other students with the same question can sit next to the student and learn what to do.

    Attending this panel made me realize that there are always new and innovative ways to approach teaching and learning, and it inspired me to think more creatively about how to solve problems in my own computer science academic work.
