Module Two Post One (Symmetrical People Make Better Dancers)

This website talk about how symmetrical people make better dancers. A research was conducted involving 183 Jamaican teenagers, ranging between 14-19 years old, who danced while their movements were captured using motion-capture cameras. These cameras are similar to those used in video games and movies to give computer-generated characters fluid movements. The researchers conducting the experiment found that men judged to be better dancers tended to have a higher degree of body symmetry. The researchers speculate that higher body symmetry might also indicate better neuromuscular coordination. Symmetry is an important part of dance because it helps dancers balance, as well as make the dance seem more appealing.

Module One Post Fourteen (The Geometry of Ballet)

This last prezi although titled the same as all the others didn’t talk about rotation, translation, or reflection like the others did. Instead, it focused on symmetry, angles, and lines. When a dancer performs an arabesque their leg must be at a 90-135 degree angle. However when performing a grand jeté the dancer’s legs must be at a 180-degree angle.(A straight line)

I was reluctant at first to use this prezi since it was titled the same as the others I assumed it would have the same information. However, it had different information and examples. When I read the title I expected it to be all on geometry, but it was quite different from what the title suggested and talked more about other topics. This was useful because it talked about angles of the studio, which I had no idea about until reading this.

Module 1 Post 15 (The Geometry of Ballet)

This last prezi https://prezi.com/28tsc8jiwg71/the-geometry-of-ballet/ didn’t have much information on rotation, translation, and reflection. Although it did talk about the angles. While performing an arabesque a dancer has to have her leg at a 90-135 degree angle. While performing a grand jete a dancer has to have her legs at 180 degrees so basically a straight line.

This was useful because normally when I view sites with the title geometry of ballet, I normally think it’ll be about geometry but this site was very different and had different examples. This will be useful because I know that angles are even involved in the studio.

Module 1 Post 12 (Mathematics Of Ballet)

https://mathofballet.weebly.com/blog

This site was like many others I found. It was someone else’s blog but they did find really good information. There is a variety of different examples of why math is involved in ballet. For example spacial formations, angles, symmetry and counting the music. All of this is important to a ballerina. When a professional company performs they need apply all of these (especially spacial formation).

This was helpful because there was a lot of examples and I have multiple different forms of math to chose from. The one I found the most useful was the spacial formations because that is very important to a ballerina.

Module One Post Nine (Mathematics in Chemistry)

Mathematics and chemistry

This brief page explains how mathematics is essential in chemistry. In chemistry mathematics is necessary to calculate concepts. This page provides a lot of links on exactly what mathematics skill you need to know for chemistry. The links show that scientific equations are used in chemistry. The website is from a university, so the information is reliable.

How a mathematical equation opened a new frontier in nanotechnology

 

This website is helpful because it displays an explanation for an excellent equation for measuring the shape and weight of nano-objects such as viruses. The equations are made by professor John Sader at the University of Melbourne. It explains that it will require more force to push heavier objects. If you accelerate a particle you measure how fast it goes to figure out the mass. That is called (MS). This website is a bit complicated but it helps you realize how math is used to measure nano-objects/ particles.

Module One Post Two (Relationship Between Mathematics and Physics)

Relationship between mathematics and physics. This site explains how mathematics and physics are closely related to each other. They were once regarded as the almost the same subject because math was used to calculate things in physics. Issac Newton even regarded geometry as the same mechanics. Some outer branches developed due to their relationship, such as calculus. It was developed due to the need in physics.

“Mathematics has already been described as “an essential tool for physics and physics has already been described as “a rich source of inspiration and insight in mathematics”.

For me, this site let’s me understand about how mathematics is used in physics. It shows how closely they are related.

A cycloidal pendulum swings at equal time intervals. This fact was discovered by Christaan Huygens through mathematical assumptions.

Module 1 Post 2 [ Mathematics and Music]

Mathematics and Music

This page provides lots of links such as videos, podcasts and articles. These links explain counting, intervals, scales, pitches, overtones, patterns, symbols, harmonies and tones. This site has gathered lots of links from trusted sources ( Such as Tedx Talks)

The AMS ( American Mathematical Society) has lots of articles of how math and music are similar. They have listed over 20 links to trusted sources such as universities like “Rice University” (William Marsh Rice University).  I think I will use this page as a place where I can gather extra information from links that I might’ve missed when researching for my topic.

4/4 = 4 quarter notes (4) in a measure. 2/2 = 2 whole notes (2) in a measure. 3/8 = 3 eighth notes (8) in a measure.

Module 1 Post 1 [Music and Mathematics ]

Music and Mathematics

This site explains a wide variety of how music can relate with mathematics. The site explains that most music pieces have a form known as “Binary” and “Ternary”  form. Binary is a musical form that has 2 sections: A and B. Sometimes it might be A-A-B-B if the composer wants to repeat a section.Ternary is a musical form that has 3 sections. The most common type for Ternary form is A-B-A formation.

This site also explains how a scale is a set of pitches used in creating pieces. Most pieces stay in one key while others change into other keys. Each key has a minor and major key. The higher a note is, the higher the hertz (Hz). A tonic note on A major would have a lower hertz while a note such as a high A would have a higher hertz.This is known as an interval.

I believe this site will be helpful to me because it provides tons of links while also providing a vast variety of why music and mathematics are related.
