...filled with notes on light and the human eye. It helped understand the laws of refraction and reflection. “Descartes’ geometry also helped to make possible discoveries in optics, relating to the law of refraction, or the amount that light is bent” (Badertscher 3). Descartes work in mathematics and cartesian system inspired him to work in optics. With the cartesian system, Descartes was able to predict the path of light, after he figured out how to measure light. “Thus all the parts of the subtle matter which are touched by the side of the sun which faces us, tend in a straight line towards our eyes at the very moment that they are opened, without impeding each other and even without being impeded by the heavier parts of the transparent bodies which are between the two: whether these bodies move in other ways, as does air, which is almost always agitated by some wind, or if they be without motion as are perhaps glass and crystal” (Descartes, Dioptrics 5). Descartes is saying that all rays from the sun traveling in a straight line towards our open eyes and they don’t get in each other’s way. Only glass or crystal might distort the straight line of light. Descartes goes on to provide examples of how to bend light. “...these balls had earlier had only a simple rectilinear motion, they will lose a part of it and acquire instead a circular motion, which can have a different proportion with that that they retain of their rectilinear motion, accordingly as the surface of the body which they...

...the most appealing problems in the classic Euclidean plane geometry. The name of Butterfly Theorem is named very straightforward that the figure of Theorem just likes a butterfly. Over the last two hundreds, there are lots of research achievements about Butterfly Theorem that arouses many different mathematicians’ interests. Until now, there are more than sixty proofs of the Butterfly Theorem, including the synthetical proof, area proof, trigonometric proof, analytic proof and so on. And based on the extension and evolution of the Butterfly Theorem, people can get various interesting and beautiful results. The definition of the Butterfly Theorem is here below: “Let M be the midpoint of a chord PQ of a circle, through which two other chords AB and CD are drawn; AD cuts PQ at X and BC cuts PQ at Y. Prove that M is also the midpoint of XY.” (Bogomolny) This is the most accurate definition currently. However, Butterfly Theorem has experienced some changes and developments. The first statement of the Butterfly Theorem appeared in the early 17th century. In 1803, a Scottish mathematician, William Wallace, posed the problem of the Butterfly Theorem in the magazine The Gentlemen’s Mathematical Companion. Here is the original problem below: “If from any two points B, E, in the circumference of a circle given in magnitude and position two right lines BCA, EDA, be drawn cutting the circle in C and D, and meeting in A; and from the point of intersection A to the centre of the circle AO...

...mathematical ideas and questions. Talking and writing about their mathematical thinking helps ELLs build word knowledge and oral expression and clarify their thinking. Discussions with the teacher or peers are also useful monitoring tools for teachers. Through listening and recording student conversations and peer problem solving, teachers can monitor individual student progress. Mathematics is no longer viewed as isolated, individualistic, or competitive. Mathematics problems are ideally suited to cooperative group discussions because they have solutions that can be objectively demonstrated. Students can persuade one another by the logic of their arguments. Mathematics problems can often be solved by several different approaches, and students in groups can discuss the merits of different proposed solutions (Robertson, Davidson, & Dees, 1994). For this and several other reasons mentioned throughout this chapter, cooperative learning takes a central place in mathematics instruction.

...Nikolai Ivanovich Lobachevsky “The Copernicus of Geometry” Part I – An Intro to the Life & Time of Nikolai Lobachevsky Nikolai Lobachevsky was born and lived in Russia from 1792 until 1856. During this historic time in Russia, one era of rulers ended and another began. In 1796, 7 decades of women rulers came to an end. Catherine the Great died in 1796 after thirty-four years as Empress of Russia. The throne then falls to her son Paul I, whose reign is cut short when he is murdered in his bed in 1801. After Paul’s demise, his son, Alexander I ascends the throne.[4] Alexander I was going to have his work cut out for him. Due to the Russians lack of trust in Western ideas at the end of the 18th century, advances in science and math in Russia where practically non-existent. In fact, the “modern” Saint Petersburg Academy was nearly abandoned. At this low point, the school had only 14 full-time staff members. Upon becoming Tsar, Alexander was determined to reform the suffering education system. He knew that advances in the areas of math & science would help to improve the strength of the military as well as make an impact on the economy of his nation. Just in the first three years after inheriting the throne, Alexander reopened the Dorpat University and opened 3 new universities, including Vilna in 1802, Kazan in 1804, and Karkov in 1804. With the opening of these new institutions, he still faced one major challenge: Who was going to teach the students all this math...

...Common Application Essay Throughout my life I have experience failure just like every other normal human being. But unlike some people I choose to learn from my mistakes and do my best to never repeat them again. One account of failure that I remember is when I failed Algebra in freshman year. Math has always been my weakest subject. I never understood or could remember all the steps and rules needed in Math. It was nothing like memorizing vocabulary in Biology or reading a book and answering the questions in English. You can’t do that in Math because unlike the other subjects, Math questions and answers are never the same. In English the “Lord of the Flies” will always be written by William Golding and in History...

...are the five words that changed the world of learning in today’s era. But what is Common Core and what makes this education curriculum so common? The Common Core State Standards Initiative is an effort to establish a common set of standards for all public schools in all states. For example, “by the end of first grade, all kids should be able to count to X, add, multiply, divide, know fractions and be able to read a chapter book” (BladdyK). Besides education standards, it standardizes things like homework and tests. This adaptation in a new standard is a work-in-progress, thus giving common core a very vague and broad feeling to it. I've heard from numerous college students within my classrooms...
