why is maths needed for computer science

However, abstract programming languages are very similar to the mathematical language that students learn in math class. In a day's worth of programming, any computer scientist is guaranteed to make a mistake. What book would cover theory for 3D game development mathematics. However, in the course of my programming work, I've picked up a lot of math and comp sci from blogs and reading, and I genuinely believe I have a decent mathematical mind. What is the radius of a circle with circumference 2π? I haven't taken any math classes above basic college calculus. (By definition, all transcendental numbers are also irrational.). While it may seem far-fetched to believe that solving the train problem above can help you solve a problem in your life, the skills that you use in framing the problem, identifying the knowns and unknowns, and taking steps to solve the problem can be a very important strategy that is applicable to other issues in life. The ratio of a circle’s circumference to its diameter is also equal to pi. I do not think Iearned anything from Project Euler, it just happened that I already knew some number theory and solved the problems. “Welcome to Introduction to Numerical Mathematics. President Obama recently called to expand access to computer science education in American schools. If you want to brush up on your math skills to be a better bargain-hunter, remember this rule: to subtract 10 from a price, you can just move the decimal place to the left by one digit. People working in a factory must be able to do mental arithmetic to keep track of the parts on the assembly line and must, in some cases, manipulate fabrication software utilizing geometric properties (such as the dimensions of a part) in order to build their products. To someone with no experience thinking or communicating in abstract languages, learning a programming language can be terrifying. Read on to learn a few reasons that math is a powerful and incredibly useful tool. If it so happens that through your reading you find something that is close to some project euler thing, your luck , but otherwise Project euler is a complete waste of time. Fields of discrete mathematics include combinatorics, graph theory, and … Project Euler cannot teach you anything effectively. So, grab that text book and start doing the practice problems. It makes sense that the average meandering ratio of rivers approaches pi, because rivers tend to bend into loops, which are circular in nature. Therefore, the radius of a circle with circumference 2π is equal to 1. Part of this debate springs from differing ideas of what constitutes a "strong background in mathematics." People who know math are therefore less likely to go into debt because they did not know how much money they had versus how much money they spent. Don’t believe me? But in day to day programming? At the most fundamental level, all of a computer’s data is represented as bits (zeros and ones). Discrete Mathematics provides an essential foundation for virtually every area of computer science, and its applications are correspondingly vast. Sure, it’s mostly equations, numbers, and some Greek letters, but math is understood the same virtually all over the world (and who knows, maybe all over the universe)! I'd recommend checking out MIT Open Courseware. 10 reasons to ignore computer science degrees Many organizations are looking beyond the CS degree to hire programmers who can deliver real results. The amount of programming-related math that you can learn without formal training is limited, but it's more than enough. Many math classes focus on the rote memorization of formulas. Edutopia® and Lucas Education Research™ are trademarks or registered trademarks of the George Lucas Educational Foundation in the U.S. and other countries. The fourth year of the Mathematics and Computer Science degree provides the opportunity to study advanced topics and undertake a more in-depth research project. For example, if you find out you like number theory, take H. Davenport -> Hardy & Wright -> Kenneth & Rosen's , study those. Subtract the discount amount from the original price of the shirt: $25.00 – $5.00 = $20.00. The number pi can also be observed all around us. Sure, it’s mostly equations, numbers, and some Greek letters, but math is understood the same virtually all over the world (and who knows, maybe all over the universe)! Don’t let your ignorance of math make you like the White Rabbit! Another good example is Oracle Academy, a free program that enables students to build fundamental computer science skills through engaging learning opportunities, including hackathons, student workshops, and even a global weather station project. Also, make sure you find texts that are actually introductory; I have become wary of slim, undecorated hardbacks labeled Elementary Foobar Theory, which tend to be elementary only to postdocs with a PhD in Foobar. A3. A strong math background develops all of the skills mentioned above. The circumference of a circle is equal to the diameter of the circle times pi. Use your knowledge of fractions to help you tell time on analog clocks that have an hour, minute, and (sometimes) second hand. To live in a mathematically-driven world and not know math is like walking through an art museum with your eyes closed. There is no knowledge that can only be gained in a classroom. Without math, you may not have enough food (or have too much food) to feed your guest! If you like Graph Theory take Reinhard Diestel's book which is freely available and study that(or check books.google.com and find whichever is more appropriate to your taste) but don't spread your attention in 999999 directions just because Project Euler has problems ranging from dynamic programming to advanced geometry or to advanced number theory, that is clearly the wrong way to go and it will not bring you closer to your goal. It can be empowering to learn about mathematical principles because it can help make sense of a world that, oftentimes, does not make much sense. Computer programming has its own languages, which are very abstract. Here’s why they might be right. Due to its relevance to language design and type theory, I would like to know more about it, but so far I have not been able to deal... For a nice, scattershot intro to bits of many kinds of CS-ish math, I recommend Godel, Escher, Bach by Hofstadter (if you haven't read it already, of course). I'm really afraid I'm going to have to back up to where I left off, get a mid-level math textbook, and invest some serious time in exercises to train myself in that way of thought. Balancing one’s bank account, for example, is an important life skill that requires math in order to subtract balances. You can use the 10 rule to quickly calculate 10 of the price and multiply it by a factor that can help you estimate price discounts quickly. From simple equalities to complex mathematical representations, learning mathematics teaches students the art of reading, comprehending, formulating thoughts, and communicating with abstract language. Learning mathematics means to consider a subject and a read a book about it and solving exercices or reading solutions, that's how you learn math. Q1. Both trains leave their origins at the exact same time early in the morning. Q2. Read on for some examples of math in nature. If you don't want to attend a class, you still need to get what the class would have given you: time in the material and lots of practice. Knowing math, and particularly fractions, can help you better tell time. My impression so far is that I'm well equipped to take these on at a conceptual level, but I'm having a really hard time with the mathematical language and symbols. Youtube and videolectures.com are also good resources for video lectures. If you feel you are not motivated it is hard to study properly. Algorithm is among the most bandied-about terms in the technology scene. A mathematical law doesn’t change because someone has a different religion than you or speaks a different language from you. The brain regions involved in higher math skills in high-performing children were associated with various cognitive tasks involving visual attention and decision-making. Well you decide. I think the time is much better invested choosing a particular branch of mathematics and studying that. Then take a break; after you have rested, go through it again in more depth. Knowledge of percentages and how to calculate them quickly can help you save time when shopping at a sale at the mall – for example, to quickly calculate a discounted price, or to determine whether you’ve been correctly charged when paying for a shirt at the store. Pi is a cool number with many unique properties. Research conducted by Dr. Tanya Evans of Stanford University indicates that children who know math can recruit certain brain regions more reliably, and have higher gray matter volume in those regions, than those who perform more poorly in math. This skill can prove handy if you find that your half-cup measure is missing. In addition to general skills important for computer science, the facts and figures of math are essential. You can move the decimal over to the left by one digit to calculate 10 off – $2.50. These classes neglect building the critical thinking and logical reasoning that help students in future math classes and computer science careers. As computer programming interacts more with our world, the importance of accurately modeling that world through mathematics grows. Reasoning is our ability to think logically about a situation. Further, educational nonprofit Destination Imagination offers lessons in the fields of STEM (science, technology, engineering, and mathematics) to teach students creative processes and empower them with skills needed to succeed in school, their careers, and beyond. Offered by University of London. 4. As the educational community focuses on this challenge, the relationship between math education and computer science is undoubtedly moving into the spotlight. If you don't want to attend a class, you still need to get what the class would have given you: time in the material and lots of practice. The universality of math is one of the many things that makes it such a powerful tool and, indeed, essential life skill. The San Francisco train will arrive in (1850/40) = 46.25 hours. You should probably look through books on topics you're personally interested in; the inherent interest should help get you over the hump. You cannot study Mathematics through Project Euler as it contains only bits and pieces(and some pretty high level pieces) that you're supposed to know in order to solve the problems. A recent study indicated that 4 out of 5 children living in Oklahoma City can’t read the hands on an analog clock to tell time. To know mathematics you have to do mathematics not programming(project euler). Becoming a computer scientist requires a fair amount of mathematical knowledge and skill. I enjoy and have success doing Project Euler, for example. Project Euler takes problems out of context and drops them in for people to solve them. While correlation may not imply causation, this study indicates that the same brain regions that help you do math are recruited in decision-making and attentional processes.
