cassiedoddDESMA9 NanoTech + Art

Nanotechnology is rapidly transforming our everyday lives; from medicine to food and cosmetics, it impacts the way we live and interact with technology. Nanotechnology looks at manipulating matter on a scale of 1 to 100 nanometers, which is much smaller than the width of a human hair. Over the past few decades, nanotechnology has evolved from a concept to a practical, transformative force with countless applications in our daily lives.

Nanotechnology traces back to physicist Richard Feynman’s famous 1959 lecture, where he envisioned the possibility of manipulating atoms and molecules at the smallest scales. This sparked interest in two primary approaches to nanotech, top-down methods, where large structures are broken down into smaller ones, and bottom-up techniques, where atoms and molecules naturally assemble into intricate nanostructures. These foundational ideas laid the groundwork for the cutting-edge developments we see today.

Richard Feynman Lecture (1959)
By the 1980s, nanotechnology had transitioned from a theoretical field into experimental science, with the invention of the scanning tunneling microscope (STM) allowing scientists to observe and change individual atoms, impacting our understanding of atomic structures. Key discoveries include buckyballs and carbon nanotubes which open up new possibilities.

Today, nanoparticles are widely used in everything from sunscreens and cosmetics to construction materials and food products. Nanoparticles’ unique properties, such as their ability to block UV radiation in sunscreens, result in them being essential in numerous industries. Interestingly, the use of nanoparticles was also used in ancient civilizations, including by Roman artists, who also used the power of nanoparticles for both decorative and functional purposes in their art.

Everyday uses of Nanotechnology
In medicine, the use of nanotechnology is even more evident with it revolutionizing drug delivery by enabling targeted treatments that reduce toxicity and enhance effectiveness. For example, Abraxane, a nanoscale anti-cancer drug, provides a safe alternative to traditional therapies. 

However, the widespread use of nanotechnology raises valid concerns, especially regarding health and environmental impacts. As nanoparticles are so small, they can penetrate deeper into the body and potentially cause unknown harm. The lack of clear labeling on nano-enabled products also creates transparency issues for consumers. It is important for researchers and policymakers to address these concerns and ensure that nanotechnology is developed and regulated responsibly.

Nanotechnology is a field that continues to evolve; however, as with any emerging technology, it is essential that there is a balance between innovation and safety.

    Hi Cassie! I really enjoyed reading your blog post this week! I liked how you began with a brief history of nanotech from Feynman’s lecture to today’s everyday applications. The part about Roman artists using nanoparticles was really interesting. I had no idea nanotech had roots that far back in art history! I also like how you mentioned the ethical concerns that come with these advancements. It’s exciting to see how nanotech is transforming things like medicine and cosmetics, but transparency and safety are just as important. Thanks for sharing!

cassiedoddDESMA9 Week 2 - Math + Art

Buckminster Fuller once said, “Everyone is born a genius, but the process of living de-geniuses them.” Nowhere is this more evident than in the way we often separate disciplines like art and mathematics; however, contrary to belief, they are deeply intertwined.  I always viewed mathematics and art as completely separate and entirely distinct from each other, almost on opposite ends of the spectrum. However, these lectures and readings have shown me how mistaken I was. It has revealed that mathematics is key to creating perspective in art, allowing artists to represent three-dimensional space on a two-dimensional surface. By using geometric principles like vanishing points and angles, artists can add depth and realism to their work. A vanishing point is where parallel lines seem to meet far away, providing the illusion of depth (Marc Franz). It’s basically a visual trick rooted in geometry that helps our brains believe we’re looking into a three-dimensional space, even though it’s j...

Surprisingly, the relationship between industrialization and art started with something as simple as the printing press. While Gutenberg usually gets the spotlight, it was actually invented much earlier, around 1040, by the Chinese (Hoh, Anchi). This invention changed the way knowledge was produced and shared. Suddenly, books could be mass-printed, making information way more accessible than ever before. Walter Benjamin touches on this in The Work of Art in the Age of Mechanical Reproduction , where he explains how this shift didn’t just affect how art was made and distributed but also transformed how people experienced it. According to Benjamin, reproducing art on a large scale stripped it of its “aura”; however, it opened a door for more people to engage with art in previously impossible ways. In other words, it was a trade-off that helped shape the modern world ( Benjamin, Walter ). Illustration of the early printing press (left) alongside Walter Benjamin’s The Work of Art in the A...

  The series of novels Strangers and Brothers by C.P. Snow investigates the concept of the 'two cultures,' which originally addresses the divide between the rich and the poor. However, it has often been misinterpreted, with the term 'two cultures' being mistakenly understood as referring to the divide between the humanities and science, a distinction that can still be found in everyday life.  I’m a political science major, which kind of feels like I’m living in both the humanities and the sciences at the same time, so I bounce between North and South Campus. And let me tell you, even though I’ve had classes on both sides, it’s pretty obvious that each one has its own vibe. North Campus is all about greenery—lots of gardens, and the sculpture garden is the perfect spot to chill, people-watch, or just listen to music while relaxing on a bench. Meanwhile, South Campus is more industrial, with a bit of an 'inner LA' feel—lots of concrete and grey, kind of like you...
