Week 8: Nanotech +Art

The conceptual roots of nanotechnology are often traced back to physicist Richard Feynman’s 1959 lecture, “There’s Plenty of Room at the Bottom,” where he imagined a future where we could manipulate individual atoms to create new materials and devices. Building on Feynman’s vision, Eric Drexler proposed in Engines of Creation, which led to the “assembler,” a nanoscale factory arm that could position atoms just as a robotic arm on a Ford assembly line arranges car parts (Vesna). Drexler and Ralph Merkle founded the Foresight Institute to advance this vision, championing a world where dirt could be restructured into hamburgers. This vision started a dispute with Nobel laureate Richard Smalley.

A breakthrough in nanotechnology came with the invention of the scanning tunneling microscope (STM) by Gerd Binnig and Heinrich Rohrer at IBM Zurich in 1981, earning them the 1986 Nobel Prize in Physics. The STM allowed scientists to feel surfaces at the atomic level. Using a tungsten needle with a tip just one atom wide, the STM scans a surface like a fingertip tracing tiny bumps, producing images of individual atoms by measuring tunneling current as the tip rasters across the material (Vesna).

Nano-structured surfaces have enabled innovative self-cleaning technologies across various industries. Fabrics coated with nanolayers, used by brands like Minicore and Dockers, repel stains while remaining breathable. Self-cleaning glass, containing titanium dioxide nanoparticles, uses sunlight to break down dirt and grease, allowing water to wash it away easily (Vesna). This technology is already used in products like BMW cars and is expected to become widespread. Additionally, self-cleaning coatings on concrete and Japan’s bullet trains reduce maintenance and energy use, showing the practical benefits of nanotechnology in everyday life (Vesna).

    Hi Paige, your breakdown of the Drexler-Smalley debate was very engaging; I hadn’t fully appreciated how philosophical that conflict was, not just scientific, but about what kind of future we want to build. I also found your explanation of the STM super clear; comparing it to a fingertip tracing a surface made a complex concept really intuitive. Your examples of self-cleaning technologies made me think about how nanotech is already quietly integrated into our daily lives, like how I never realized my workout clothes might contain silver nanoparticles. It's amazing how something so microscopic can have such a visible impact.

    Hi Paige! I really like how your post provides an overview of how nanotechnology evolved from visionary concepts to practical applications in the real world. I especially appreciated the connection between Feynman’s early ideas and today’s real-world innovations like self-cleaning surfaces. I also think that it is cool to see how tools like the STM have made it possible to actually work at the atomic level. The everyday uses of nanotech, from bullet trains to clothing, really show how far we've come. Great work!

Event 3: Sholeh Asgary: Atmosphere of Sound

Image
Visiting Sholeh Asgary: Atmosphere of Sound at the CNSI Art Sci Gallery was such a cool opportunity I got to do this quarter! The installation, Qanat , centered around a traditional Iranian rug, struck a powerful balance between cultural memory, sound, and light. A single pin spot beam lights up the central motif of the rug, symbolizing a fountain, while sounds of water play through the space. Hanging above, a pendulum microphone fed those sounds into a bass amplifier beneath the rug, creating a feedback loop that responded to both environmental sound and visitor presence. My own photo! This piece was powerful because it made the visitor part of the artwork. The rug wasn’t just symbolic; it helped carry and amplify the sound. Where I stood, sat, or lay down, my movements changed the sounds in the space. A similar piece that came to mind was Rafael Lozano-Hemmer’s Pulse Room , where the artwork responds to the viewer’s heartbeat, making their body an essential part of the installation....

Week 9: Space + Art

Image
In this week’s lectures, Professor Vesna and articles explore how our understanding of space has evolved through historical developments. One of the most influential pieces this week was the documentary-style video, Contemporary Space Age Development . It traces the origins of space exploration during the Cold War, beginning with the 1945 Trinity atomic bomb test. The video shows how nuclear power and the policy of "massive retaliation" led to the development of ICBMs and, eventually, the 1957 launch of Sputnik (Vesna). Sputnik had enormous symbolic value; it sparked global paranoia and marked the moment the Cold War reached beyond Earth. National Park Service. "Trinity Site."
