Pi has always been an interesting concept to me. A number that is infinitely being calculated seems almost unbelievable. This number has perplexed many for years and years‚ yet it is such an essential part of many peoples lives. It has become such a popular phenomenon that there is even a day named after it‚ March 14th (3/14) of every year! It is used to find the area or perimeter of circles‚ and used in our every day lives. Pi is used in things such as engineering and physics‚ to the ripples created

think that the Moh’s scale of hardness ends with the diamond at number 10‚ but really there are 2 more things Moh forgot to put as he lacked time. One‚ a woman’s heart at 11 and Mathematics at 12. Ok‚ I made up the last part‚ but in my eyes and most of the general public’s it’s mostly true. I first met Math when I was young. He gave me a hard time. Back in the days of flashcards and simple addition‚ I shied away from the numbers and rapid computations. It wasn’t because I sucked at it or I hated

Math Today When We Have Devices Luke A. Douglas Ashford University MAT222: Intermediate Algebra Instructor Robb March 3rd‚ 2014 Math Today When We Have Devices Some think that math has no place in the world‚ and I must admit that I am one of those people. I understand that we do use math everyday but in an age of technology it’s no longer needed as much as it once was; or is it? I theorize that math is still an important tool that we must remain proficient at to keep up with the times

home‚ you’re using math principles. People have been using these same principles for thousands of years‚ across countries and continents. Whether you’re sailing a boat off the coast of Japan or building a house in Peru‚ you’re using math to get things done. How can math be so universal? First‚ human beings didn’t invent math concepts; we discovered them. Also‚ the language of math is numbers‚ not English or German or Russian. If we are well versed in this language of numbers‚ it can help us make

your free time? Who do you like to spend your free time with? What gives you a sense of purpose or boost your self-esteem? Everyone wants to feel like they belong somewhere. People need positive face to face contact with others to feel like they have a sense of purpose. A group you could say you fit in with.

equivalent decimal values for presentation to or input from humans; computer programs express literals in decimal by default. (123.1‚ for example‚ are written as such in a computer program‚ even though many computer languages are unable to encode that number precisely.) Both computer hardware and software also use internal representations which are effectively decimal for storing decimal values and doing arithmetic. Often this arithmetic is done on data which are encoded using some variant of binary-coded

cryptography is the ability to send information between participants in a way that prevents others from reading it. In this book we will concentrate on the kind of cryptography that is based on representing information as numbers and mathematically manipulating those numbers. This kind of cryptography can provide other services‚ such as • integrity checking—reassuring the recipient of a message that the message has not been altered since it was generated by a legitimate source • authentication—verifying
