CREATE-X is celebrating the eight CREATE-X entrepreneurs included on the recent Forbes 30 Under 30 list. They include founders Sohan Choudhury of Flint, Garrett Smiley of Sora Schools, Sarah Hamer of RetailReady, Bruno Geoly and Mia Rath of Lumindt, Rishabh Kewalramani of BackBar, Safir Monroe of UnDelay, and Tamara Zubatiy of Barometer. 

Forbes 30 Under 30 is a yearly list of notable young people in art, entertainment, healthcare, science, and more. CREATE-X has had founders on this list 11 times since 2017. Read about how some of the 2025 honorees got their start — and their advice for other aspiring entrepreneurs.

 

Sohan Choudhury: Flint

The Beginning

“I decided to start Flint because I was passionate about education as a space, and I felt that there's a lot more that could be done with AI in education. When we started the company in May 2023, the perspective of a lot of schools and teachers on AI was very negative because they were looking at how students were using it to cheat. As technologists, my co-founder and I asked, ‘Is there something more we can do to change this narrative and perspective?’ We started building tools for teachers and students and partnering with schools.” 

The CREATE-X Experience

“CREATE-X gave me the first avenue to work on my own thing. When I was a first-year or sophomore in college, I didn't know that was possible. I thought once I graduate I'll maybe get an engineering job and just do that. But CREATE-X changed that story for me by giving me another path. As I went down that path with my first company, the advisors we had through CREATE-X were incredibly helpful to us.”

The Outlook

“Day to day, a lot of the work we do is pretty unglamorous. We’re dealing with bugs that our customers are facing, or we’re cold emailing people. It's easy to get lost in the weeds. The Forbes announcement was a great way for us to reflect on what we've done so far. It's such a team effort, so it was validating to get recognition on a broader level for the work we're doing.”

Advice for Success

“If you can code or are interested in coding, pull on that thread. If you can build your own prototypes, which is becoming easy to do nowadays with AI, it will help you get further with your ideas. The second piece of advice is to take your idea and try to convince someone to pay for it. Even if you have a tool that will save your peers time with studying, build something basic for it, but then ask them to pay you five bucks. People speak with their money. There were times at Flint where we had a lot of positive feedback, and then we asked people to pay, and all of the constructive feedback came out.”

 

Garrett Smiley: Sora Schools

The Beginning

“I was a military brat, so I moved around to a lot of different schools and experienced a bunch of different styles of learning. I went to school in the early 2010s, right when laptops were entering the classroom. We had YouTube, Khan Academy, Coursera, and all these things hit the mainstream. Because of my background, education was a very active question in my life. I saw how these tools completely supercharged my learning and changed the relationship between student and teacher and the dynamics of the classroom.”

The CREATE-X Experience

“CREATE-X asked us to think about large systemic problems we were passionate about. That pushed me to think seriously about how I could help solve a problem in this space. It was helpful to put into practice many of the startup lessons that I'd been studying forever, and it was great to have a community of founders before anyone believed in us.”

The Outlook

“I'm inspired by Forbes’ emphasis on education, so to be recognized in that context was extra special. We’re in 46 states and 16 countries, so it's great to see the breadth that Sora has accomplished. We're bringing this style of education to different communities that, in many cases, have never considered something like this before. Seeing our students accepted into places like Harvard, Georgia Tech, and other elite institutions shows families that you can have a transformative education like Sora and still go to those schools if it makes sense.“

Advice for Success

“Use your free time in school to try the things you're thinking about. Sora was an idea I thought I would circle back to when I was 30 or 40 and had money and credibility. But I was shocked by how open people were to listening to a young person with a few resonating ideas. There's no qualification or age requirement to provide value and improve people's lives.”

 

Sarah Hamer: RetailReady

The Beginning

“I met my co-founder, Elle, while we were working at a company called Stord, which is also an Atlanta-based startup. Elle and I were put on a project going to a warehouse every week for six months. We saw some gaps in supply chain software and decided to solve them since nothing was on the market. So I applied to Y Combinator and got in, and now we’re here.”

The CREATE-X Experience

“CREATE-X was my first foray into starting a business. It gave me confidence, and I learned a lot of lessons with my first business. I think I would've made a lot of mistakes starting a business now if I hadn't had that experience in college. For example, knowing how important user interviews are, how you’ll probably fail here and there, start small, then scale — the principles you take for granted that CREATE-X taught.”

The Outlook

“I started at Microsoft right out of Georgia Tech and was there for a year and a half. It was a very stable, well-paying job. I followed my gut to leave and join a startup called Stord and then followed it again to leave and start RetailReady. Quitting your stable day-to-day job takes a lot, and I’m proud I took the chance. We’ve grown fast, and it’s a huge honor to be included on the Forbes 30 Under 30 list in the first year of being in business. We’re really happy about it.” 

Advice for Success

“When you can, take the chance and do it. Even if you’re not sure, always believe you’ll win. A lot of it is mental fitness, believing what your gut is telling you. There will be times when you’ll say, ‘This probably isn’t the right move to make.’ Listen to that.”

 

Bruno Geoly: Lumindt

The Beginning

“An inflection point for me was the summer of 2021. I was working at SpaceX, and at the same time, my friends and I had started this Web3 crypto company dealing with NFTs. And I was like, I can mix these two things together to do something cool, something important. The idea of what Lumindt is wasn't even a sparkle in my eye at that time. But I knew I wanted something of my own, doing these two things I enjoy — entrepreneurship and high-level engineering. And that's what I did.”

The CREATE-X Experience

“CREATE X was a way for me and my co-founder to stay accountable for our work. When you have an idea you want to turn into a business, it’s hard to stay on yourself to do that. CREATE-X was a good way for us to always have a thing to go to and ideate what we’re working on. And there was a little bit of competition. You see all of these other people making progress, and it’s good inspiration and a motivator to continue working.”

The Outlook

“My co-founder and I were very appreciative of being included on the Forbes 30 Under 30 list. Looking back on what I wanted to do in college, I just loved building stuff. And to have this small team of people, and we’re able to build what we want, and there's cohesion and camaraderie, I'm very happy with that. It's fun to go to work every day and work with the people I do. And not only that, we now have a business that impacts the world.”

Advice for Success

“If you want to be an entrepreneur, that's a skill set like anything else. If you want to get better at karate, you practice karate. If you want to be a better entrepreneur, you have to practice entrepreneurship. You'll learn a lot about yourself — what problems you like to solve and what problems you need help solving.”

 

Want to Build Your Own Startup?

Georgia Tech students, faculty, researchers, and alumni interested in developing their own startups are encouraged to apply to CREATE-X's Startup Launch, which provides $5,000 in optional seed funding and $150,000 in in-kind services, mentorship, entrepreneurial workshops, networking events, and resources to help build and scale startups. The program culminates in Demo Day, where teams present their startups to potential investors. The deadline to apply for Startup Launch is Monday, March 17. Spots are limited. Apply now.

Generative AI tools such as ChatGPT and Midjourney can produce text, images and videos far more quickly than any one person can accomplish by hand.

But as someone who studies the societal impacts of AI, I’ve noticed an interesting trade-off: The technology can certainly save time, but it does so precisely to the extent that the user is willing to surrender control over the final product.

For this reason, generative AI is probably most useful for things we care about the least.

Ceding Creative Control

Let’s use the example of AI image generators. You probably have a rough idea of how they work. Just type what you want – “a panda surfing,” “a piece of toast that is also a car” – and the generative tool draws it.

But this glosses over the countless possible iterations of the desired image.

Will the image appear as a watercolor painting or a pencil sketch? How lifelike will the panda be? How big is the wave? Is the toast-car parked or moving? Is there anyone inside of it?

When the images are generated, these questions have been answered – but not by the user. Rather, the generative AI tool has “decided.”

Of course, the user can be more specific: Imitate the style of Monet. Make the wave twice the height of the panda. Maybe the panda should look worried, since it isn’t used to surfing.

You can also pop open an image editor and modify the output yourself, down to the individual pixel. But, of course, drafting detailed instructions and revising the image take time, effort and skill. Generative AI promises to lighten the load. But as every manager knows, exercising control is work.

The Devil is In the Details

In all art and expression, power lies in the details.

In great paintings, not every brushstroke is planned – but each is carefully considered and accepted. And its overall effect on the viewer depends on all those considered brushstrokes together.

Filmmakers shoot take after take of the same scene, each subtly or radically different. Only a small fraction of that footage makes it into the final cut – the fraction that the editors feel does the job best. Great artists use their judgment to ensure every detail helps to achieve the effect they want.

Of course, there’s nothing new about putting someone else in charge of the details. People are used to delegating authority – even about matters of expression – to marketers, speechwriters, social media managers and the like.

Generative AI makes a new sort of contractor available. It’s always on call, and in certain ways it is very technically competent.

But compared with skilled humans, it has a limited ability to understand what you want. Moreover, it lacks intention, contemplation and the comprehensive mastery of detail that yield great expressive achievements – or even the comprehensive idiosyncrasy that spawns very unique ones.

Ask ChatGPT for a film script, plus casting and shooting instructions. It will give you neither Francis Ford Coppola’s masterpiece “The Godfather” nor Tommy Wiseau’s bizarre “The Room.”

You could, perhaps, approach a masterpiece, or a true oddity. But to do so, you’d have to exercise more and more time, more and more effort, and more and more control.

An Era of ‘Cheap Speech’

What generative AI makes possible, above all, is low-effort, low-control expression.

In the time I took to write and revise this article, I could have used ChatGPT to generate 200 grammatically correct, well-structured articles, and then I could have posted them online without even reading them. I wouldn’t have had to carefully parse each word and decide whether it really helped me make my point. I wouldn’t have even had to decide whether I agreed with any of the AI-generated write-ups.

This is not a merely hypothetical example. Low-quality, AI-generated e-books of ambiguous provenance are already making their way into online vendors’ catalogs – and into the libraries those vendors serve.

Similarly, using image generators, I could now flood the internet with superficially appealing images, dedicating only a fraction of a second to decide whether any of them express what I want them to express or achieve what I want them to achieve.

But in doing so, I would not just be skipping over drudgery. Writing, drawing and painting are not just labor but processes of considering, reviewing and deciding exactly what I want to put out into the world. By skipping over those processes, I surrender that decision-making process to the AI tool.

Some scholars argue that the internet has produced an era of “cheap speech.” People no longer have to invest a lot of resources – nor even face the judgment of their neighbors – to broadcast whatever they want to the world.

With generative AI, expression is even cheaper. You don’t even have to make things yourself to put them out into the world. For the first time in human history, the ability to produce writing, art and expression has been decoupled from the necessity of actually paying attention to what you’re making or saying.

When Intention and Effort Matter

I suspect that great art, journalism and scholarship will still demand great attention and effort. Some of that effort may even include custom-developing AI tools tailored to an individual artist’s concerns.

But unless people become much better at curation, great work will be increasingly difficult to locate amid the flood of low-effort content, which is also known as “AI slop.”

It’s appropriate that generative AI becomes more useful the sloppier its users are willing to be – that is, the less they care about the details.

I could end with some dire prognosis – that working artists and writers will be replaced with mediocre automation, that online discourse will get even stupider, that people will isolate themselves in personalized cocoons of AI-generated media.

All these things are possible. But it’s probably more useful to offer a suggestion to you, the reader.

When you need an image or a piece of writing, take a moment to decide: How important are the details? Would the process of making this yourself, or working with a collaborator or contractor, be useful? Would it yield a better output, or give me the chance to learn, or begin or strengthen a relationship, or help you reflect on something important to you?

In short, is it worth putting in real care and effort? The answer will not always be yes. But it often will.

Art, writing, films – these are not just products, but acts. They are things humans make, through a process of thousands of little decisions that encompass what we stand for and what we want to say.

So when it comes to art, expression and argument, if you want it done right, it’s probably still best to do it yourself.The Conversation

When you look at your surrounding environment, it might seem like you’re living on a flat plane. After all, this is why you can navigate a new city using a map: a flat piece of paper that represents all the places around you. This is likely why some people in the past believed the earth to be flat. But most people now know that is far from the truth.

You live on the surface of a giant sphere, like a beach ball the size of the Earth with a few bumps added. The surface of the sphere and the plane are two possible 2D spaces, meaning you can walk in two directions: north and south or east and west.

What other possible spaces might you be living on? That is, what other spaces around you are 2D? For example, the surface of a giant doughnut is another 2D space.

Through a field called geometric topology, mathematicians like me study all possible spaces in all dimensions. Whether trying to design secure sensor networks, mine data or use origami to deploy satellites, the underlying language and ideas are likely to be that of topology.

The Shape of the Universe

When you look around the universe you live in, it looks like a 3D space, just like the surface of the Earth looks like a 2D space. However, just like the Earth, if you were to look at the universe as a whole, it could be a more complicated space, like a giant 3D version of the 2D beach ball surface or something even more exotic than that.

While you don’t need topology to determine that you are living on something like a giant beach ball, knowing all the possible 2D spaces can be useful. Over a century ago, mathematicians figured out all the possible 2D spaces and many of their properties.

In the past several decades, mathematicians have learned a lot about all of the possible 3D spaces. While we do not have a complete understanding like we do for 2D spaces, we do know a lot. With this knowledge, physicists and astronomers can try to determine what 3D space people actually live in.

While the answer is not completely known, there are many intriguing and surprising possibilities. The options become even more complicated if you consider time as a dimension.

To see how this might work, note that to describe the location of something in space – say a comet – you need four numbers: three to describe its position and one to describe the time it is in that position. These four numbers are what make up a 4D space.

Now, you can consider what 4D spaces are possible and in which of those spaces do you live.

Topology in Higher Dimensions

At this point, it may seem like there is no reason to consider spaces that have dimensions larger than four, since that is the highest imaginable dimension that might describe our universe. But a branch of physics called string theory suggests that the universe has many more dimensions than four.

There are also practical applications of thinking about higher dimensional spaces, such as robot motion planning. Suppose you are trying to understand the motion of three robots moving around a factory floor in a warehouse. You can put a grid on the floor and describe the position of each robot by their x and y coordinates on the grid. Since each of the three robots requires two coordinates, you will need six numbers to describe all of the possible positions of the robots. You can interpret the possible positions of the robots as a 6D space.

As the number of robots increases, the dimension of the space increases. Factoring in other useful information, such as the locations of obstacles, makes the space even more complicated. In order to study this problem, you need to study high-dimensional spaces.

There are countless other scientific problems where high-dimensional spaces appear, from modeling the motion of planets and spacecraft to trying to understand the “shape” of large datasets.

Tied Up In Knots

Another type of problem topologists study is how one space can sit inside another.

For example, if you hold a knotted loop of string, then we have a 1D space (the loop of string) inside a 3D space (your room). Such loops are called mathematical knots.

The study of knots first grew out of physics but has become a central area of topology. They are essential to how scientists understand 3D and 4D spaces and have a delightful and subtle structure that researchers are still trying to understand.

In addition, knots have many applications, ranging from string theory in physics to DNA recombination in biology to chirality in chemistry.

What Shape Do You Live On?

Geometric topology is a beautiful and complex subject, and there are still countless exciting questions to answer about spaces.

For example, the smooth 4D Poincaré conjecture asks what the “simplest” closed 4D space is, and the slice-ribbon conjecture aims to understand how knots in 3D spaces relate to surfaces in 4D spaces.

Topology is currently useful in science and engineering. Unraveling more mysteries of spaces in all dimensions will be invaluable to understanding the world in which we live and solving real-world problems.The Conversation

The team has published an analysis outlining a path toward a viable hemp-based building insulation market in the U.S. Hemp insulation can be used in place of traditional fiberglass batt insulation and reduce the carbon footprint of buildings, but hemp materials currently cost twice as much. (Photo: Candler Hobbs)

It’s a fairly niche product now, but a new study from Georgia Tech engineers suggests insulation made from hemp fibers could be a viable industry in the U.S., creating jobs, a manufacturing base, and greener homes and buildings at the same time.

Making the switch could slash the impact of one of the biggest sources of greenhouse gas emissions: Buildings account for roughly 1/5 of emissions globally. By some estimates, using hemp-based products would reduce the environmental impact of insulation by 90% or more. 

The Georgia Tech researchers’ work, reported this month in the Journal of Cleaner Production, is one of the first studies to evaluate the potential for scaling up U.S. production and availability of hemp-based insulation products.

Eye

Four million Americans suffer from glaucoma, an incurable eye disease that slowly degrades peripheral vision and eventually leads to blindness. Researchers at Georgia Tech have discovered a potential way to stop this degradation and possibly save people’s vision before it’s too late.

Raquel Lieberman, a professor in the School of Chemistry and Biochemistry and the Parker H. Petit Institute for Bioengineering and Bioscience, and her lab team have discovered two new antibodies with promise to treat glaucoma. The antibodies can break down the protein myocilin, which, when it malfunctions, can cause glaucoma.

Lieberman’s group recently published this research in the Proceedings of the National Academy of Sciences: Nexus.

Protein Problems

Myocilin is just one of hundreds of thousands of proteins that make up the human body. In the eye, an especially delicate balance of proteins and fluid enables sight. The aqueous humor, a clear fluid, bathes the lens that helps focus light into the retina. In a healthy eye, the fluid drains regularly, but if something prevents the fluid from circulating, it increases pressure.

“Your eyeball is kind of like a basketball,” explained Lieberman. “If you want it to work optimally, it has to be pressurized.” 

Lieberman’s team has learned that if myocilin mutates, it clumps up and prevents aqueous humor from draining, increasing eye pressure. If left unmanaged, glaucoma and — eventually — blindness will occur. 

Antibody Answer

Lieberman’s lab characterized two new antibodies that each, in their unique way, can destroy myocilin gone rogue. One binds in a way that does not prevent myocilin from clumping; the other prevents the protein from aggregating. Both effectively break down myocilin so it no longer blocks the aqueous humor from flowing. 

“These exciting results provide proof of concept that targeted antibodies for mutant myocilin aggregation could be therapeutic,” said Alice Ma, a Ph.D. graduate who worked on the research. “This represents a new paradigm for treating other diseases associated with protein clumping, like Alzheimer’s. These studies hold the potential to save the eyesight of millions of glaucoma patients.”

The findings have been the culmination of nearly two decades of research with Lieberman’s close collaborator, University of Texas at Austin chemical engineering Professor Jennifer Maynard, whose group helped discover the two antibodies that responded to the mutation. Lieberman’s group then worked to understand how the antibodies functioned, determining the two that most successfully broke down the protein. 

“This study builds on 10 years of work that explains how myocilin folds to how to break it down,” Lieberman said. “I am at a very fortunate place in my career where this fundamental research coalesces into what we could use clinically.”

Treatment Transformation

Lieberman hopes the antibodies can help treat glaucoma patients, particularly those with early onset glaucoma, often children. She now has a research collaboration with Rebecca Neustein, a physician at Emory University who treats these young patients. 

“She doesn't have much hope to give her patients for curing glaucoma,” Lieberman said. “So she was very excited that we could do some genotyping and figure out who these antibodies can help.”

Lieberman’s research offers a clearer future for millions suffering from glaucoma and those at risk of developing the disease. By leveraging antibodies to target and break down malfunctioning myocilin, this discovery not only paves the way for new treatments for glaucoma but also opens doors for addressing other protein-aggregation diseases like Alzheimer’s, Parkinson’s, and even Type 2 diabetes.

Bradford “Brad” Greer (bottom) and Kevin Ge (top), both 2023 graduates from the George W. Woodruff School of Mechanical Engineering, have taken their startup, CADMUS Health Analytics, from a classroom project to a promising health tech company. In 2023, CADMUS was accepted into the CREATE-X Startup Launch program. Over the 12-week accelerator, CADMUS made significant strides, and program mentors provided expert guidance, helping the team focus their direction based on real-world needs. Their partnership with Northeast Georgia Health System (NGHS) was a direct result of connections made at Startup Launch’s Demo Day.

How did you first hear about CREATE-X?

We did the CREATE-X Capstone with an initial team of seven people, later transitioning to Startup Launch in the summer. Capstone required a hardware product, but for several reasons, we pivoted to software. By that point, we already had a grasp on the problem that we were working on but didn't have the resources to start working on a large hardware product.

Why did you decide to pursue your startup?

One of our close buddies was an emergency medical technician (EMT), and we also had family connections to EMTs. When we were doing our customer interviews, we found out that Emergency Medical Services (EMS) had multiple problems that we thought we'd like to work on and that were more accessible than the broader medical technology industry. 

What was Startup Launch like for you?

Startup Launch seemed to transition pretty seamlessly from the Capstone course. We came to understand our customer base and technical development better, and the program also led us through the process of starting and running a company. I found it very interesting and learned a whole lot.

What was the most difficult challenge in Startup Launch?

Definitely customer interviews. We spent a lot of time on that in the Startup Launch classes. It's a difficult thing to have a good takeaway from a customer interview without getting the conversation confused and being misled. We didn't mention the product, or we tried to wait as long as possible before mentioning the product, so as to not bias or elicit general, positive messaging from interviewees. 

We're working in EMS, and the products we are building affect healthcare. EMS is a little informal and a little rough around the edges. Many times, people don't want to admit how bad their practices are, which can easily lead to us collecting bad data. 

What affected you the most from Startup Launch?

The resources at our fingertips. When we were running around, it was nice to be able to consult with our mentor. It's great having someone around with the know-how and who's been through it themselves. I revisit concepts a lot.

How did the partnership with NGHS come about?

During Demo Day, we met a Georgia state representative. He put us in touch with NGHS. They were looking for companies to work with through their venture arm, Northeast Georgia Health Ventures(NGHV), so we pitched our product to them. They liked it, and then we spent a long time banging out the details. We worked with John Lanza, who's a friend of CREATE-X. He helped us find a corporate lawyer to read over the stuff we were signing. It took a little back and forth to get everything in place, but in September of last year, we finally kicked it off.

What’s the partnership like?

We provide them a license to our product, have weekly meetings where experts give feedback on the performance of the system, and then we make incremental changes to align the product with customer needs. 

While we're in this developmental phase, we're kind of keeping it under wraps until we make sure it’s fully ready. Our focus is primarily on emergent capabilities that NGHS and other EMS agencies are really looking for. Right now, the pilot is set to be a year long, so we're aiming to be ready for a full rollout by the end of the year. 

How did you pivot into this other avenue for your product?

EMS does not have many resources. That makes it not a popular space as far as applying emerging technologies. There's only competition in this very one specific vein, which is this central type of software that we plug into, so we're not competing directly with anyone.

EMS agencies, EMTs, and paramedics - the care that they give has to be enabled by a medical doctor. There has to be a doctor linked to the practices that they engage in and the procedures that they do. With the product that we're making now, we want to provide a low-cost, plug-and-play product that'll do everything they need it to do to enable the improvement of patient care. 

How are you supporting yourself during this period? 

I was paying myself last year, but we're out of money for that, so we're not currently paying for any labor. It's all equity now, but our burn rate outside of that is very low. The revenue we have now easily covers the cost of operating our system. I'm also working part-time as an EMT now. This helps cover my own costs while also deepening my understanding of the problems we are working on.

How are you balancing your work?

It's hard to balance. There's always stuff to do. I just do what I can, and the pace of development is good enough for the pilot. Every week, and then every month, Kevin and I sit down and analyze the rate at which we're working and developing. Then we project out. We're confident that we're developing at a rate that'll have us in a good spot by September when the pilot ends.

What’s a short-term goal for your startup?

Kevin and I are trying to reach back out and see if there's anyone interested in joining and playing a major role. The timing would be such that they start working a little bit after the spring semester ends. I think most Georgia Tech students would meet the role requirements, but generally, JavaScript and Node experience as well as a diverse background would be good.

Where do you want your startup to be in the next five years?

I want to have a very well-designed system. Despite all the vectors I’m talking about for our products, everything should be part of the same system in place at EMS agencies anywhere. I just want it to be a resource that EMS can use broadly.

Another issue in EMS is standards. Even the standards that are in place now aren’t broadly accessible. I think that these new AI tools can do a lot to bridge the lack of understanding of documentation, measures, and standards and make all of that more accessible for the layperson.

What advice would you give students interested in entrepreneurship?

Make sure the idea that you're working on, and the business model, is something you enjoy outside of its immediate viability. I think that's really what's helped me persevere. It's my enjoyment of the project that's allowed me to continue and be motivated. So, start there and then work your way forward.

Are there any books, podcasts, or resources you would recommend to budding entrepreneurs?

 I’d recommend Influence to prepare for marketing. I have no background in marketing at all. Influence is a nice science-based primer for marketing.

 I reread How to Win Friends and Influence People. I am not sure how well I'm implementing the concepts day-to-day, but I think most of the main points of that book are solid.

I also read The Mom Test. It's a good reference, a short text on customer interviews.

Here in Atlanta, the Jimmy Carter Presidential Library and Museum has been part of my daily life for years. Parks and trails surrounding the center connect my neighborhood to the Martin Luther King Jr. National Historical Park downtown and everything in between.

At the end of December 2024, thousands of people walked to the library to pay their respects to the former president as he lay in repose. The cold, snow and darkness of the evening were a stark contrast to the warmth of the volunteers who welcomed us in. Our visit spiraled through galleries exhibiting records of Carter’s life, achievements and lifelong work promoting democracy around the world.

U.S. presidents have been building libraries for more than 100 years, starting with Rutherford B. Hayes. But the urge to shape one’s legacy by building a library runs much deeper. As a scholar of libraries in the Greek and Roman world, I was struck by the similarities between presidential and ancient libraries – some of which were explicitly designed to honor deceased sponsors and played a significant role in their cities.

Trajan’s Library

The Ulpian Library, a great library in the center of Rome, was founded by Emperor Trajan, who ruled around the turn of the second century C.E. Referenced often by ancient authors, it could have been the first such memorial library.

Today, someone visiting Rome can visit Trajan’s Column, a roughly 100-foot monument to his military and engineering achievements after conquering Dacia, part of present-day Romania. A frieze spirals from bottom to top of the column, depicting his exploits. The monument now stands on its own. Originally, however, it was nestled in a courtyard between two halls of the Ulpian Library complex.

Most of what scholars know about the library’s architecture comes from remains of the west hall, an elongated room almost 80 feet long, whose walls were lined with rectangular niches and framed by a colonnade. The niches were lined with marble and appear to have had doors; this is where the books would have been placed. Writers from the first few centuries C.E. describe the library having archival documents about the emperor and the empire, including books made of linen and books bound with ivory.

Trajan dedicated the column in 113 C.E. but died four years later, before the library was complete. Hadrian, his adoptive son and successor, oversaw the shipment of Trajan’s cremated remains back to Rome, where they were placed in Trajan’s Column. Hadrian completed the surrounding library complex in 128 C.E. and dedicated it with two identical funerary inscriptions to his adopted parents, Trajan and Plotina. Scholars Roberto Egidi and Silvia Orlandi have argued that Trajan’s remains could later have been transferred from the column into the library hall.

Memorial Model

Either way, I would argue that Trajan’s decision to have his remains included in the library complex, instead of in an imperial mausoleum, established a model adopted by other officials at a smaller scale. In the eastern side of the Roman empire – what is now Turkey – at least two other library-mausoleum buildings have been identified.

One is the library at Nysa on the Maeander, a Hellenistic city named for the nearby river. Under the floor of its entry porch is a sarcophagus with the remains of a man and a woman, possibly the dedicators, that dates to the second century C.E., the time of Hadrian’s reign.

Another is the Library of Celsus, the most recognizable ancient library today, found in the ancient city of Ephesus. Named after a regional Roman consul and proconsul during the reign of Trajan, the building was founded by Celsus’ son, designed as both a place of learning and a mausoleum.

The library’s ornate, sculpted facade contained life-size female statues, making it an immediately recognizable landmark. Inscriptions identify the statues as the personifications of Celsus’ character, elevating him into a role model: virtue, intelligence, knowledge and wisdom.

Upon entering the room, the funerary character of the library became quite literal. The hall was designed like the Ulpian Library, but a door gave access to a crypt underneath. This held the marble sarcophagus with the remains of Celsus, the patron of the library. The sarcophagus itself was visible from the hall, if one stood in front of the central apse and looked down through two slits in the podium.

An endowment covered the library’s operational expenses in ancient times, as well as annual commemorations on Celsus’ birthday, including the wreathing of the busts and statues and the purchasing of additional books.

Power and Knowledge

These two provincial libraries highlight how sponsors hoped to be associated with the virtues a library fosters. Books represent knowledge, and by dedicating a library, one asserted his possession of it. Providing access to learning was an instrument of power on its own.

Beyond the handful of memorial libraries, many other ancient Roman public libraries were great cultural centers, including the Forum of Peace in Rome, dedicated by Emperor Vespasian; the Library of Hadrian in Athens; and the Gymnasium in Side, a city in present-day Turkey.

The most magnificent libraries combined access to manuscripts and artworks with spaces for meetings and lectures. Several had great leisure areas, including landscaped sculptural gardens with elaborate water features and colonnaded walkways. Literary sources and material evidence testify to the treasures that were held there: busts of philosophers, poets and other accomplished literary figures; statues of gods, heroes and emperors; treasures confiscated as spoils of war and exhibited in Rome.

Like the Ulpian Library itself, they continued the long tradition of Hellenistic public libraries, established by the most famous library of antiquity: the Library of Alexandria. Founded and lavishly endowed by the Hellenistic kings of Egypt, the Ptolemies, the building was meant to portray the king as a patron of intellectual activities and a powerful ruler, collecting knowledge from conquered civilizations.

In ancient Greece and Rome, anybody who could read had access to public libraries. Rules of use varied: For example, literary sources imply that the Ulpian Library in Rome was a borrowing library, whereas an inscription from the Library of Pantainos in Athens explicitly forbid any book to be taken out.

But these buildings were also meant to shape their sponsors’ legacies, portraying them as benevolent and learned. Presidential libraries in the United States today follow the same principle: They become monuments to the former presidents, while giving back to their local communities.The Conversation

Small rocks and debris fly near Earth, many just passing by. Some, however, come too close to Earth, with a potential threat of collision. Defending Earth from these unwanted objects is a growing concern globally. Planetary defense explores threat characterization, risk mitigation, and policy to defend Earth. One mitigation approach is sending an impactor to collide with the target object to deflect its trajectory from the original course toward Earth. This approach, known as kinetic deflection, is practical for intruders with a diameter up to a few hundred meters.

NASA’s Double Asteroid Redirection Test (DART), led by Johns Hopkins University’s Applied Physics Laboratory, was the first full-scale kinetic deflection mission to test how kinetic deflection could effectively push an asteroid measuring 150 meters in diameter. The 580-kg spacecraft (impactor) collided with the target asteroid, Dimorphos, at a speed of 6.1 km/second on September 26, 2022, making the target’s speed 2.7 mm/s. This speed change could gradually make the course deviate from the original one. The more time that elapses after impact, the further it moves away from the Earth. Even though Dimorphos was not a threat before the impact, it was chosen as a test target for DART’s kinetic deflection test.

Georgia Tech Professor Masatoshi Hirabayashi’s critical contribution to DART was recently published in Nature Communications. The study, “Elliptical ejecta of asteroid Dimorphos is due to its surface curvature” analyzed the behavior of fragments coming out by the high-speed DART impact and their push of the asteroid. This work was in collaboration with Professor Fabio Ferrari from Politecnico di Milano, who jointly published the study, “Morphology of ejecta features from the impact on asteroid Dimorphos.”  

Imagine a cannonball flying through the air and hitting a concrete wall. The wall shutters and fragmented pieces disperse at high speeds. Those smaller fragments, called ejecta, are known to be a key factor in controlling the asteroid push.

The study found that the ejecta from the impact site on Dimorphos highly depends on the asteroid’s shape. As a rule of thumb, a cannonball hitting a flat concrete wall creates ejecta departing from the wall at an angle of about 45 degrees from the wall’s surface. The cloud of ejecta thus looks like a waffle cone. However, if the concrete wall’s surface is tilted against the impact direction, the fragment ejection changes, making the ejecta structure differ even if the impactor has the same mass and speed. 

“This changes the asteroid push dramatically. Dimorphos has a squashed round shape, like an M&M,” Hirabayashi explained, “If the impact is large, more ejecta fly out of the surface but are more affected by surface tilts. This process makes the ejecta deviate from the ideal direction, reducing the asteroid push.” 

For the DART impact on Dimorphos, the study identified the impact scale and the asteroid’s rounded surface lowered the asteroid push by 56% compared to when Dimorphos was tested as an entirely flat wall. Thus, sending a large impactor does not mean a big push, and considering how to send impactors strategically is necessary. One way to keep the asteroid push effective is to send multiple small impactors rather than a single large impactor. This way, each small impactor may avoid the target’s rounded shape, and the net asteroid push by multiple impacts can be more efficient than the single impactor.

“Sending multiple smaller impactors not only results in a higher asteroid push but also potentially saves operational cost and  increases tactical flexibility for deflection," Hirabayashi said.

Ferrari’s study offered crucial information for Hirabayashi’s conclusions. “We used Hubble Space Telescope’s images and numerical simulations to quantify a viable mechanism of the ejecta evolution and successfully estimated ejected particles’ mass, velocity, and size. We also found complex interactions of such particles with the asteroid system and solar radiation pressure, i.e., sunlight pushing ejecta particles,” Ferrari said. “Documenting how ejecta looks over time offers crucial insights into how the DART impact acted on ejecta, giving tight constraints on the target asteroid’s properties.”

NASA’s DART mission was a success, and Hirabayashi’s study discovered an innovative approach to kinetic deflection, offering new potential for its future demonstration in space. He is building a new capability of characterizing a target’s properties beneficial for planetary defense, such as mass, size, composition, etc., at limited observational conditions. This is aligned with the fast reconnaissance concept, a new community effort that develops planetary defense strategies to identify these properties within a limited time and resources. This work continues to evolve Georgia Tech into a key player in planetary defense, connecting international communities.
