Assignment 2: Math History Reflection - Blog Response 15
My presentation was focused on the history of limits to infinity. It was really interesting to research on how it all started, especially before a time of mathematics where Arabic numerals and algebraic notation were absent. The majority of my presentation was focused on the findings of Archimedes and the area of a circle via infinitesimals. It incorporated a clever use of a proof by contradiction method, which somewhat surprised me as I thought that would have been more of a modern notion. Due to time constraints, it was impossible to cover the entire history of limits with every detail. It stretches over a millennia and the most interesting part is that the order of development started with integrals, then derivative, and finally limits. This is the opposite order of what is being taught in schools!
One of the main things I want to take away from this and show students is that infinity is not mere value that we plug in the limits notation. It seems like due to the extensive amount of analytic work that students have to in a calculus class, they get desensitized to the concept of the idea and ignore the beauty and complications that come with it. Infinity was deemed as beast by mathematicians, and even the very best failed to wrestle with such concepts. Perhaps by presenting these historical moments, students will be able to relate and realize why it's okay to find calculus confusing. We have prime examples of moments of epic collaboration and battles between pairs of mathematicians like Kepler and Galileo, and Leibniz and Newton. And we can't forget that none of their work wouldn't occur without the work of Ancient Babylonians, Greek, Egyptian, and Indian mathematicians that pioneered the early foundations.

Dancing Euclidean Proofs - Blog Response #14
Although I consider math as art, I never considered the medium of conveying it through dance and human body movements. I was surprised and enlightened to see that there is a cultural pursuit in mathematics that utilizes both body and mind. One of the statements posed in the article is that the body's natural symmetries can be used to make simple geometric shapes like circles and triangles. I find this interesting because its such an obvious and unobvious fact at the same time. Perhaps the beauty we were looking for in mathematics was always right in front of our very eyes, or body I should say.
I appreciate the amount of visible effort that was put into the choreographs of the dances. When watching the video, the performances were very fluid and smooth in transitions, which makes excellent clarity of the proofs that they were depicting. As the article describes, the process of going through various iterations of dance moves, concern in maintaining mathematical integrity, and the deliberate choice of the environmental location and sounds. All these considerations brought harmony in the arts and math, making the final product visually and auditorily pleasing, without reducing the technical contents of Euclid's proofs.
Incorporating such activities in a high school classroom will definitely spark interest in students. Physical activity is almost never seen in a math classroom, so this could be an excellent alternative for students. Availability of classroom or outdoor space may pose as a constraint, as well as funding for specialized camera equipment like drones if top view shots are desired.
Was Pythagoras Chinese? - Blog Response #13
I definitely do think that acknowledging non-European sources of mathematics makes an impact to students' learning. Often times, students and even myself take for granted on the origins of mathematics that we get taught in the classroom. There is so much opportunity to create discourse in a classroom and promote diversity amongst students, especially in a math classroom where it's rare to see such actions take place. Leaving out important details of history and only focusing on European contributions can distort a student's view of mathematics. When we talk about the origins of how math came to be, and not just the techniques on solving problems, it provides a more immersing learning experience and gives students with diverse backgrounds a chance to have moments of realizations and possibility relate their own cultures.
When I see naming's of mathematical concepts, the immediate question that I always have is why are some theorems named after mathematicians, while others are named by functionality, like the Fundamental Theorem of Calculus. While I do understand that recognizing the individual who discovered the theorem is done out of respect, we often have inconsistencies like we have seen with Pascal's Triangle and Pythagoras Theorem. Sure, we can take it with a grain of salt and accept it as it is, but it still feels wrong to eliminate a story that represents decades if not centuries worth of collaborative work across the globe. Perhaps we should try to aim theorems to be named by descriptors or we as teachers should clarify names of theorems whenever necessary.

Euclid and Beauty - Blog Response #12
Euclid's Elements has proven itself to be one of the greatest mathematical textbooks to have ever exist. I believe that one of the the reasons why Euclid and his book have been so important and popular for centuries is that it is able to uncover ground without circular reasoning. I speculate that there must have been frustration amongst mathematicians before Euclid when it came to logically proving ideas, despite how blatantly and intuitive it seems. For example, if one were to look at a diagram of a square, how do you know that it is indeed a square? I think that it's the general concept of not taking things for granted, and making sure we always pay attention to our surroundings is what we have valued throughout these years. Also, if I remember correctly, Euclid's fifth postulate raised many eyebrows until hyperbolic geometry was studied. This is a great example to always question the obvious!
There is elegance in the way we prove that things that occur in the world. Is there beauty in defining the given truth? I believe so. It's quite fascinating how we can fix a couple axioms, and then construct complex theorems out of them. Euclid's work was mainly based on the 2-D plane yet it served as a basis for relatively and related ideas like determining the shape and dimension of the universe. The beauty comes from how we can set some simple, intuitive facts (axioms) and develop them into sophisticated and crazy ideas through logical reasoning and proofs.

Assignment #1 Reflection - Blog response #10
My group and I tackled problem 1.2.4 from 5000 Years of Geometry.
Here is the link to our presentation:
https://docs.google.com/presentation/d/1FsASoA7QqRUaOuKEkFRpz4ao2k-pwjKoL-1nAPdiKfA/edit?usp=sharing
When I first looked at the problem, it seemed rather simple. When observing the provided formulas of calculating the diagonals of 3 by 4 rectangle, it seemed to just work magically. That's when the deceptiveness of the simplicity shocked me. How did the Babylonians manage to calculate the diagonal of a rectangle from its sides without resorting to the Pythagorean rule? When we showcased the modern solution, its quite obvious that we use our handy $a^2 + b^2 = c^2$. The challenge came when we hand to decipher how the Babylonians approached this problem.
After researching the clay tablet in question, I realized that the Babylonians, given their limitations of modern math tools, figured out ingenious methods of calculating diagonals and had a wide list of rectangle sides written in terms of linear combinations to produce the correct diagonal length. I still have some unanswered questions of regarding their discovery of their methodologies, but it astonishes me nonetheless.
When we were doing our computations to show our work, we used the calculation of expanding binomials was prevalent. As an extension, I wanted to showcase how we can intuitively teach students on how we expand binomials through pattern recognition and imagery. Although we as teacher candidates have explored deep into math concepts and are aware of how handy Pascal's Triangle is when it comes to expanding binomials, students in high school often times do not get to learn these concepts. If you observe the BC curriculum and the list of topics that are taught, combinatorics and probability no longer exist. I noticed that senior students in math classes only know how to expand binomials through FOIL.
I believe that combinatorics and probability have excellent content when it comes to developing thinking strategies to solve puzzles and play games, which is listed as a BC curricular competency. My aim with this extension is to remind us that we can teach students solve seemingly painful computational problems through creativity and restore teachings of certain content that has been lost in the past few years.

Babylonian-style base 60 multiplication table for 45 - Blog Response #5
Here are some pairings of numbers that multiply to 45 that utilize base 60 fractions:
$$2 \times 22,30 = 45$$ since $2 \times 22.5 = 45$ so we can represent $0.5$ as $\frac{30}{60}$.
$$4 \times 11,25$$ since $4 \times 11.25 =45$ so we can represent $0.25$ as $\frac{15}{60}$.
$$6 \times 7,30 = 45$$ since $6 \times 7.5 = 45$ so we can represent $0.5$ as $\frac{30}{60}$.
$$8 \times 5,37,30 = 45$$ since $8 \times 5.625 = 45$ so we can represent $0.62$ as $\frac{37}{60}$ and $0.005$ as $\frac{5}{60^2}$.
$$12 \times 3,45$$ since $12 \times 3.75 =45$ so we can represent $0.75$ as $\frac{45}{60}$.

History of time calculations, base 60 and base 12 - Blog Response #4
The two articles show how historical practices in measuring time and developing numerical systems are intertwined. The division of time into days, hours, and minutes has connections to the natural world and has evolved over time. It is an accumulation of astronomical observations, cultural practices, and historical developments. It is quite interesting how numbers like these may appear as simple or natural divisions, but they represent a story of refinement. Although the Babylonians used a base-60 sexagesimal system, it still influences how we measure time today. In fact, their historical number system reflects an extremely sophisticated understanding of mathematics and has left a lasting legacy on how we approach calculations and measurements. The remnants of their civilization can still be seen when it comes to angles, circles and spheres, and of course, time!
There seems to be different reasonings between the two articles when it comes to why a base-60 system was chosen. The first article simply suggests that it is because 60 is a convenient number to express multiple fractions. It also learns towards historical context and practical aspects of time keeping in a more general sense. The second article goes in more depth and provides various theories. It focuses more on the technical aspects of numerical systems and their mathematical implications.

Why Base 60? - Blog Response #3
The Crest of the Peacock introduction - Blog Response #2
It is quite surprising to read about the adverse affects of colonization when it comes to overwriting history in a mathematical context. It is disheartening to hear that European ideologies dominated in the 19th century, resulting in the devaluation of colonized peoples contributions. We see the same occurrence even further back in history as the Eurocentric model credits Ancient Greece for the origins of math and not Egypt nor Mesopotamia. I like how the book goes into more depth and shows us gradual improvements of figures that holistically represent the trajectory of mathematical development. Although the later figures depict confusing arrows that point in various directions and even having multiple of them converge to a singular spot, it emphasizes how math and culture is intertwined through diverse eras of countries and civilizations. Math is a collaborative process and we should aim to recognize all those who have contributed.
I also find it interesting that there are sources and possible factual evidence that describe Pythagoras travelling around the world to places like India. It makes me wonder if there are documented cases of any other notable scholars at time decided set off on foot or sail to explore the world in search of knowledge. Something that also came to my knowledge in recent years is that math concepts like place-holder values, solving quadratic equations, and the infamous Pythagoras theorem have all made their appearance in various regions. I wouldn't have ever guessed that the word "algebra" is of Arabic origin if I never took the time to inquire about it. I hope that our society continues to attribute mathematical findings to their appropriate contributors and accept it in all its diverse forms!

Why teach math history? - Blog Response #1
My initial opinions on how math history should be incorporated into teaching is to give students a tour of how historical and ancient mathematics were tackled by past mathematicians. Ever since the modernization and formalization of math, students will be inevitably introduced to rigorous theorems and definitions. There are many math concepts that I struggled to grasp but something that shocked and gave me a sense of validation is when I learned that these concepts were giving headaches to the very mathematicians that developed them. This is why I think implementing history is a great way to help students gain an intuitive understanding of hard concepts by putting them through the lens of a period where information was not widely available. In addition, I was always inclined to believe that learning math is more individual focused during my time in school. But in fact, history says quite the opposite. Collaboration is the catalyst that drove generations of mathematicians from all over the world to work together and uncover the mysteries of our world.
After reading the article, I appreciate the fact that they touched on the concepts of dialectical learning. Indeed, history is like the naïve and confused kid in their first year of high school figuring out where their classes are and who their friends are. While mathematics is now the successful and mature adult who’s got their life figured out. The contrast between developmental and polished stages of work provides completeness and an appropriate beginning and end to a wonderful story. I also like how the article points out math as a cultural endeavor. To gain practical skills and maximize utility are not the only reasons to learn math. In fact, to say to oneself, “I want to study math because it seems cool,” is a simple yet excellent reason to learn math as well. Students are often stripped of their creativity once they get lost in memorizing definitions to score well in exams. In fact, there is sublimity in mathematics, and we often times forget that art is inherently embedded in math.
The article has further strengthened my belief that teaching historical math is important to students. I wasn’t aware that articles that included integration methods and models like this existed since I was rarely exposed to it as a high school student. Just recently, a professor of mine brought up the Navier-Stokes equation during a lecture and said that whoever can solve it first will be granted one million dollars! We need to pose more thought-provoking to students and provide the necessary motivation that they deserve. Thanks to the article, I hope to challenge myself in the future and incorporate these ideas in my classroom.
