Space is the zone beyond the earth's atmosphere that is considered a vacuum, where there is no air to breath or atoms to move light.¹ Shown in the video “Powers of ten”(Figure A), space is infinitely bigger than any person could imagine. They are able to show this by continuously zooming out by powers of ten starting at one square meter². After watching the video, the meaning of life seemed to have a significantly less weight to it.



A majority of people know that space is a part of the large unknown void that exists beyond reach, but a few scientists and engineers believe it can be as close as a simple structure. There are proposals for a space elevator(Figure B) that would lift mass out of earth's atmosphere against gravity.³ The main idea is to use a cable connected at one end to the earth, and at the other end to a satellite that is propelled forward with acceleration to move at the same rate as earth's rotation⁴. While that may sound crazy, there are many people and scientists today that believe it will be possible. In fact in an article published by MIT in 2019, it may be coming sooner than we think. According to MIT, by making an anchor on the moon instead of the earth and using a cable as a connection it might even be possible with materials we have today.⁵ (Figure C)

  NanoTech + Art:  This week we looked into the development of nanotech over the years and analyzed its connections to art. The term nanotech was coined by Japanese professor and scientist Norio Taniguchi¹ to describe the process scientists have developed to manipulate at the scale of a single atom. Nano is the greek root for dwarf and tech is an abbreviation for technology hence technology used to work with extremely small scales. So small in fact, that a single nanometer is approximately three atoms long². Seen below (Figure 1) is a diagram that shows what scale a nanometer would fall under; between a singular protein and the size of a virus.  Figure 1:  1 *, Name. “Size-Comparison-Bio-Nanoparticles Nanometer Scale Comparison Nanoparticle Size Comparison Nanotechnology Chart Ruler.” Wich Research Lab , 3 Aug. 2017, https://www.wichlab.com/nanometer-scale-comparison-nanoparticle-size-comparison-nanotechnology-chart-ruler-2/. While the technology has been developing ...

 Tuesday April 5, 2022 Lifeguard Sketch in 2pt perspective Throughout my entire life my passions have always been both math and art, and I have struggled to find common ground between them. For the longest time I was convinced that art was an entirely creative system and math always had a right answer, but when I started to study the formal drawing styles of architecture I have found commonalities between them. Through school, internships, and on site drawing I continue to develop an understanding for the interaction between math and art.  DaVinci's Virtuvain Man  Pictured above is the vitruvian man, drawn and conceptualized by Leonardo DaVinci.The Vitruvian man is an image of a man superimposed upon himself and enveloped within a circle and a rectangle. The scale of the geometries allow for the artistic aspect of the drawing to connect to the mathematical sense of proportion. DaVinci took the ideas of proportion and “ideal” senses of measure and applied them to the art w...
