Illusions/ reality

Sammy Keane 
After doing some research I learned that perception is the process in which people are aware of the
objects and events in the external world. I had always known the basics of what perception meant but
I was unaware of the stages that were a part of it. Perception occurs in five stages: stimulation,
organization, interpretation-evaluation, memory, and recall. People have studied perception as a way
to solve a particular problem, arise simply from intellectual curiosity about themselves and the world.
(Britannica). 
When thinking about perception and the way that our eyes work to tell our brain what we are looking at,
I started to do research on optical illusions and the different ways they can play a trick on both our eyes
and brains. “Optical Illusions can use color, light, and patterns to create images that can be deceptive
or misleading to our brains. The information gathered by the eye is processed by the brain, creating a
perception that in reality, does not match the true image” (Optics)
Look at the image below? 
Are the pinwheels moving?

The answer is no, the wheels are not turning. This is because of the Moiré effect. “The Moiré effect is a
visual perception that occurs when viewing a set of lines or dots that is superimposed on another set of
lines or dots, where the sets differ in relative size, angle, or spacing can produce interesting and beautiful
geometric patterns” (techtarget). In mathematics, physics, and art, moiré patterns are large-scale
interference patterns that can be produced when an opaque ruled pattern with transparent gaps is
overlaid on another similar pattern. This can be seen in black and white images as well as colored
images. Because of the repetition of the beautiful geometric patterns, one's eyes see a moving pattern
tricking your mind into thinking the image is actually moving when in reality it is not. 
Below are some other examples of Moire effect optical illusions that also play a trick on your mind. 
As an aspiring artist, I am very interested in these optical illusions because I too want to create images
that can affect the viewer's brain upon first glance. I am currently working on an optical illusion piece
that pairs neon colors with repeating black lines to alter the viewers' sense of perception and depth in
the work.

JPL Visit 2

On our second trip to the Jet Propulsion Laboratory campus, the majority of the day was focused on the tree of life project being run by the arts team. We had many of our questions answered about the project, and witnessed first-hand the process the team takes in generating and refining their projects based on the research and findings of the NASA scientists. My main question in regards to the tree of life dealt with how the team planned to create a cube-sat which had the ability to last the duration of the project, 200 years, since no such thing has ever been done before. My favorite brainstorming session activity was writing down every question we had about the project on sticky notes and putting them up on the wall. I wish our questions had all been answered because I think the project is still very early on and a lot of people had really great questions to ask. We briefly viewed a few of the things we had seen during the first visit, including the clean room with the more-develop...

Blog #7- Sammy Keane

Sammy Keane Blog #7  Since I was unable to attend the second JPL field trip due to unfortunate events, I found myself looking throughout NASA’s dense website. Juno, NASA’s mission to Jupiter, really stood out to me. Launched on August 5, 2011, the goal of this mission was to understand the origin and evolution of Jupiter. Juno is a solar-powered spacecraft that’s observations will lead to a better understanding of the formation of our solar system and planetary systems discovered around other stars (eyes on the solar system). In addition to that, Juno would look for solid planetary core, map its magnetic field, measure water and ammonia in its atmosphere, and finally observe auroras (nasa.gov). Juno did not arrive at Jupiter until July 4th of 2016. Reading into Mission Juno allowed me to understand more about Jupiter, a planet that I before knew nothing about. For example, written on October 24,19, data from Juno has helped scientists discover that the swirling ban...

Blog #7: JPL -Sophie Ungless

The majority of our time during this visit to JPL consisted of working with the A-Team to go over the Tree of Life project, which we were introduced to during our first visit last month. The last time we learned about it, I left feeling really confused about exactly what the project was and how it has relevance, so being able to inquire more on this trip was helpful. That being said, though, I am still having a hard time wrapping my head around what the goal of the mission is. It's clear that they were inspired by how we can eventually create a mission that has the ability to arrive at Proxima B, and the drive behind the Tree of Life is this idea of time and longevity. However, the team still doesn't seem clear about how the information they gain from this project can be applied to a future mission involving Proxima B. Or if they do know, they aren't effectively articulating it to the general public, which I believe is going to be vital for keeping interest in the 200 year ...
