An ink diffusion model developed at Georgia Tech

Calculating and visualizing a realistic trajectory of ink spreading through water has been a longstanding and enormous challenge for computer graphics and physics researchers.

When a drop of ink hits the water, it typically sinks forward, creating a tail before various ink streams branch off in different directions. The motion of the ink’s molecules upon mixing with water is seemingly random. This is because the motion is determined by the interaction of the water’s viscosity (thickness) and vorticity (how much it rotates at a given point).

“If the water is more viscous, there will be fewer branches. If the water is less viscous, it will have more branches,” said Zhiqi Li, a graduate computer science student.

Li is the lead author of Particle-Laden Fluid on Flow Maps, a best paper winner at the December 2024 ACM SIGGRAPH Asia conference. Assistant Professor Bo Zhu advises Li and is the co-author of six papers accepted to the conference.

Zhu said they must correctly calculate and simulate the interaction between viscosity and vorticity before they can accurately predict the ink trajectory.

“The ink branches generate based on the intricate interaction between the vorticities and the viscosity over time, which we simulated,” Zhu said. “Using a standard method to simulate the physics will cause most of the structures to fade quickly without being able to see any detailed hierarchies.”

Zhu added that researchers had yet to develop a method for this until he and his co-authors proposed a new way to solve the equation. Their breakthrough has unlocked the most accurate simulations of ink diffusion to date.

“Ink diffusion is one of the most visually striking examples of particle-laden flow,” Zhu said.

“We introduce a new viscosity model that solves for the interaction between vorticity and viscosity from a particle flow map perspective. This new simulation lets you map physical quantities from a certain time frame, allowing us to see particle trajectory.”

In computer simulations, flow is the digital visualization of a gas or liquid through a system. Users can simulate these liquids and gases through different scenarios and study pressure, velocity, and temperature.

A particle-laden flow depicts solid particles mixing within a continuous fluid phase, such as dust or water sediment. A flow map traces particle motion from the start point to the endpoint.

Duowen Chen, a computer science Ph.D. student also advised by Zhu and co-author of the paper, said previous efforts by researchers to simulate ink diffusion depended on guesswork. They either used limited traditional methods of calculations or artificial designs. 

“They add in a noise model or an artificial model to create vortical motions, but our method does not require adding any artificial vortical components,” Chen said. “We have a better viscosity force calculation and vortical preservation, and the two give a better ink simulation.”

Zhu also won a best paper award at the 2023 SIGGRAPH Asia conference for his work explaining how neural network maps created through artificial intelligence (AI) could close the gaps of difficult-to-solve equations. In his new paper, he said it was essential to find a way to simulate ink diffusion accurately independent of AI.

“If we don’t have to train a large-scale neural network, then the computation time will be much faster, and we can reduce the computation and memory costs,” Zhu said. “The particle flow map representation can preserve those particle structures better than the neural network version, and they are a widely used data structure in traditional physics-based simulation.”

Pursuing entrepreneurship is an exciting and rewarding experience. You have the power to solve real-world problems and make an impact. Here are six things you can do to begin your entrepreneurial journey.

1. Identify a Problem You’re Interested in Solving

We often gravitate toward familiar problems, but it's crucial to explore beyond our immediate surroundings. Take the time to venture off campus and learn about problems faced by small businesses, corporations, and communities. Engaging with diverse groups will help you uncover unique challenges that you might not have considered. We accept startups in a variety of industries, from fashion to healthcare.

2. Understand the Problem Before Creating a Solution

It's tempting to rush into building a solution once you've identified a problem. However, it's essential to thoroughly understand the problem first. Before you start building, conduct at least 10 – 20 customer discovery interviews. This will give you valuable insights into the problem you're solving and help you validate your business thesis.

3. Start With Your Business Thesis

Formulate a clear business thesis: "X will buy Y because of Z." Here, X represents your target customer, Y is your product, and Z is the reason they will purchase it. As you engage with potential customers, refine your hypothesis based on their feedback. This iterative process will help you develop a product that meets real needs.

4. Build a Version 1 of Your Product

This is easier than it sounds and can be very low-tech to start. Concentrate on developing the core functionality of your product that addresses the primary pain point for your users. This unlocks user insights that can help you know if and where to pivot your solution.

5. Think About Your Business Model

While you don't need to have a concrete business model from the start, it's beneficial to brainstorm potential models. Consider how your product could generate revenue and sustain itself. Your business model can evolve as you gain more insights and experience.

6. Put in the Time

Launching a startup requires a significant time commitment and focus. You can create real momentum when you can dedicate consistent time.

 

Looking for more support on your entrepreneurial journey? Be sure to check out Startup Launch, a 12-week accelerator that helps you move from idea/prototype to your first customer. You have access to expert mentors, exclusive founder-focused workshops, vendor discounts, and $5,000 in seed funding. 

The application deadline is Monday, March 17, for the summer cohort. 

A previous info session on Startup Launch and a Startup Launch sample application are available to help students prepare. Attend CREATE-X events to get insights into entrepreneurship, workshop business ideas, find teammates, and prepare your Startup Launch applications. For additional questions, email create-x@groups.gatech.edu.

There was a time when artists representing two of America’s biggest homegrown musical genres wouldn’t get a look in at the Grammys.

Hip-hop and house both have their origins in the 1970s and early 1980s – in fact, they recently celebrated a 50th and 40th birthday, respectively. But it was only in 1989 that an award category for “best rap performance” started recognizing hip-hop’s contribution to U.S. music, and house had to wait another decade, with the introduction of “best dance/electronic recording” in 1998.

At this year’s awards, taking place on Feb. 2, hip-hop and house artists will be among the most talked about. House duo Justice and Kendrick Lamar, a hip-hop superstar who incorporates elements of house himself, are among those looking to pick up an award. Meanwhile, a nomination for a collaboration between DJ Kaytranada and rapper Childish Gambino shows how artists from both genres continue to feed off each other.

And while both genres are now celebrated for their separate contributions to the music landscape, as a scholar of African American culture and music, I am interested in their commonality: Both are distinctly Black American artforms that originated on the streets and dance floors of U.S. cities, developing a devoted underground following before being accepted by – and transforming – the mainstream.

The Pulse of the 1970s

The roots of hip-hop and house music both lie in the seismic shifts of the late 1970s, a period of sociopolitical unrest and electronic experimentation that redefined the possibilities of sound.

For hip-hop, this was expressed through the turntable manipulation pioneered by DJ Kool Herc in 1973, when he extended and looped breakbeats to energize crowds. House music’s innovators turned to the drum machine to create the genre’s foundational four-on-the-floor dance rhythm.

That rhythm, foreshadowed by Eddy Grant’s 1977 production of “Time Warp” by The Coachouse Rhythm Section, would go on to shape house music’s distinct pulse. The track showed how electronic instruments such as the synthesizer and drum machine could recast traditional rhythmic patterns into something entirely new.

This dance vibe – in which a base drum provides a steady four-four beat – became the heartbeat of house music, creating an enduring structure for DJs to layer basslines, percussion and melodies. In a similar way, Kool Herc’s breakbeat manipulation provided the scaffolding for MCs and dancers in hip-hop’s formative years.

Marginalized communities in urban centers like Chicago and New York were at the forefront of these innovations. Despite experiencing grinding poverty and discrimination, it was Black and Latino youth – armed with turntables, drum machines and samplers – who made these groundbreaking advances in music.

For hip-hop, this meant manipulating breakbeats from songs like Kraftwerk’s “Trans-Europe Express” and “Numbers” to energize b-boys and b-girls; for house, it meant extending disco’s rhythmic pulse into an ecstatic, inclusive dance floor. Both genres exemplified – and continue to exemplify – the ingenuity of predominantly Black and Hispanic communities who turned limited resources into cultural revolutions.

From this shared origin of technological experimentation, cultural resilience and creative ingenuity, hip-hop and house music grew into distinct yet globally influential movements.

The Message and the MIDI

By the early 1980s, both genres had found their feet.

Hip-hop emerged as a powerful voice for storytelling, resistance and identity. Building on the foundations laid down by DJ Kool Herc, artists like Afrika Bambaataa emphasized hip-hop’s cultural and communal aspects. Meanwhile, Grandmaster Flash elevated the genre’s technical artistry with innovations like cutting and scratching.

By 1984, hip-hop had evolved from its grassroots beginnings in the Bronx into a cultural movement on the cusp of mainstream recognition. Run-DMC’s self-titled debut album released that year introduced a harder, stripped-down sound that departed from disco-influenced beats. Their music, paired with the trio’s Adidas tracksuits and gold chains, established an aesthetic that resonated far beyond New York City. Music videos on MTV gave hip-hop a new medium for storytelling, while films like “Beat Street” and “Breakin’” showcased the features and tenets of hip-hop culture: DJing, rapping, graffiti, breaking and knowledge of self – cementing its cultural presence, and presenting it to a world outside the U.S.

But at its core, hip-hop remained a voice for the voiceless that sought to address systemic inequities through storytelling. Tracks like Grandmaster Flash and the Furious Five’s “The Message” vividly depicted the reality of living in poor, urban communities, while Public Enemy’s “Fight the Power” and Tupac Shakur’s “Keep Ya Head Up” became anthems for social justice.

Together these artists positioned hip-hop as a platform for resistance and empowerment.

Becoming a Cultural Force

Unlike hip-hop’s lyrical storytelling, house music focused on the physicality of rhythm and the collective experience of the dance floor. And as hip-hop moved away from disco, house leaned into it.

Italy’s “father of disco,” Giorgio Moroder, showed the way with his pioneering use of synthesizers in Donna Summer’s “I Feel Love.” Over in New York, Larry Levan’s DJ sets at Paradise Garage demonstrated how electronic instruments could create immersive, emotionally charged experiences as a club that centered crowd participation through dance and not lyrics.

By 1984, Chicago DJs Frankie Knuckles and Ron Hardy were repurposing disco tracks with drum machines like the Roland TR-808 and 909 to create hypnotic beats. Knuckles, known as the “Godfather of House,” transformed his sets at the Warehouse club into euphoric experiences, giving the genre its name in the process.

House music thrived on inclusivity, served as a safe space for Black and Latino members of the LGBTQ+ communities at a time when hip-hop was severely unwelcoming of gay men. Tracks like Jesse Saunders’ “On & On” and Marshall Jefferson’s “Move Your Body” celebrated freedom, love and unity, encapsulating its liberatory spirit, as rap music and hip-hop culture embarked on its mainstream journey with songs like Run DMC’s “Sucker M.C.s (Krush Groove)” and Salt-N-Pepa debuted their album “Hot, Cool, & Vicious.”

As with hip-hop, by the the mid-1980s house music had become a cultural force, spreading from Chicago to Detroit, to New York and, eventually, to the U.K.’s rave scene. Its emphasis on repetition, rhythm and electronic instrumentation solidified its global appeal, uniting people across identities and geographies.

Mainstays in Modern Music

Despite their differences, moments of crossover highlight their shared DNA.

From the late 1980s, tracks like Fast Eddie’s “Yo Yo Get Funky” and the Jungle Brothers’ “I’ll House You” merged house beats with hip-hop’s lyrical flow. Artists like Kaytranada and Doechii continue to blend the two genres today, staying true to the genres’ legacies while pushing their boundaries.

And technology continues to drive both genres. Platforms like SoundCloud have democratized music production, allowing emerging artists to build on the decades of innovations that preceded them. Collaborations, such as Disclosure and Charli XCX’s “She’s Gone, Dance On,” highlight their adaptability and enduring appeal.

Whether through hip-hop’s lyrical narratives or house’s rhythmic euphoria, these genres continue to inspire, challenge and transcend.

As the 2025 Grammy Awards celebrate today’s leading house and hip-hop artists and their contemporary achievements, it is clear that the legacies of these two genres are mainstays in the kaleidoscope of American popular music and culture, having come a long way from back-to-school park jams and underground dance parties.

Russell Dupuis

As you move your computer mouse around the screen or scroll on your phone to read these words, you’re using technology Russell Dupuis helped enable. Same for when you turn on an LED light bulb or scan groceries at the self-checkout.

The underlying technologies for those common devices are compound semiconductors manufactured using techniques Dupuis first demonstrated nearly 50 years ago. His work made it possible to mass produce and commercialize these semiconductors for LEDs, lasers, solar cells, and more.

Now his contributions have been recognized with the Japan Prize, one of a few internationally recognized awards regarded by much of the scientific community as second only to the Nobel Prize.

“Professor Russell Dupuis’ breakthrough led to the commercialization of compound semiconductor production. It has become the foundation upon which our modern information society is built,” the Japan Prize Foundation wrote in announcing Dupuis’ selection.
