Dae Wook explaining the GMT2 manufacturing

“Each of the GMT’s seven primary mirrors is 8.4 meters in diameter and takes approximately four years to create. The final stage of work for segment 2 — front surface polishing — took just ten months, significantly faster than for segment 1 due to new polishing and metrology techniques invented at the University of Arizona. With these techniques established, future GMT mirrors should pass through the pipeline faster. Watch a short interview with Dr. Dae Wook Kim of the University of Arizona where he explains these techniques.” Also, please, read the full GMTO Newsletter article here.

Vedant Janapaty’s (Silver Creek High School) Python Coding Project

Hello, my name is Vedant Janapaty and I worked on a research project with Professor Daewook Kim at the University of Arizona. Our project simulated Snell’s Law using Python Code. Snell’s Law is a formula used to describe the relationship between the angles of incidence and refraction, with regards to light. This project sought to plot both reflection and refraction using python code. The initial code accounted for refraction, the ability for light to pass through the surface. I extended this code to account for reflection. My results are summarized in this video. The original Python code is from the Vlabs project.
