Countries trade with each other for a variety of reasons, including to obtain resources, access new markets, and achieve economies of scale. Trade allows countries to specialize in the production of certain goods and services, and to exchange those goods and services with other countries in order to meet the needs and wants of their citizens.
One of the main reasons countries trade with each other is to access resources that are not readily available within their own borders. For example, a country with a shortage of oil may trade with a country that has an abundance of oil in order to meet its energy needs. Similarly, a country with a lack of arable land may trade with a country that has a surplus of agricultural products in order to feed its population.
Another reason countries trade with each other is to access new markets for their goods and services. By exporting their products to other countries, companies within a country can increase their sales and revenue, which can drive economic growth and job creation. For example, a small country with a limited domestic market may trade with a larger country in order to access a larger customer base and increase its competitiveness.
Finally, countries may trade with each other in order to achieve economies of scale. By specializing in the production of certain goods and services and trading with other countries that also specialize in the production of certain goods and services, countries can reduce their costs of production and increase their efficiency. This can lead to lower prices for consumers and increased profits for businesses.
In conclusion, countries trade with each other for a variety of reasons, including to access resources, access new markets, and achieve economies of scale. Trade allows countries to specialize in the production of certain goods and services and to exchange those goods and services with other countries in order to meet the needs and wants of their citizens.
I enjoyed this book as both a coming of age story, a success story, a story about cryptology, and mathematics. In between her autobiographical narration, Sarah provides some fun mathematical puzzles. This is the second book I've read on my own, self study of cryptography. At fifteen and a half I was the youngest, though there were a couple others nearly as young. With the help of a mathematician mentor, she invented a new "trap door" algorithm that was much faster than the state-of-the-art algorithms. But mathematics aside, it was still a refreshing read of stories of Sarah's youth and her family, and an entertaining account of her preparation and performance in competitions.
In Code: A Mathematical Journey by Sarah Flannery, David Flannery (9780761123842)
At the company, she was supervised by some gi This is a fun little book by a young woman who found some degree of fame in the field of cryptography. If mental math logic leaves your brain hurting, I wouldn't pick this up. I thought about those who had toiled away through the centuries at unraveling the mysteries of this subject, motivated by nothing more than a passionate desire to know. This is one heck of a good book. Other threads, running from brief descriptions of her grandparents to her father's teaching methods and her relationship to family in the face of a media frenzy, give her story added depth, warmth and humor. In Code is a heartwarming story that will have readers cheering Sarah on. Though it turned out that the algorithm couldn't be used for public key encryption, she got quite a lot of attention for her achievements.
She learned how to code algorithms in the Mathematica computer language. Among the subjects I address are problem solving and critical thinking. Supplemental Materials What is included with this book? I walked a middle ground in that I read a large portion of the math stuff, but I did hit a wall where I finally decided to move along to the narrative. She shares her journey in ways that help others to see that learning math and solving problems can really be fun. I had tried to read Kahn's Codebreaking many years ago but was only able to get a third of the was through.
In Code; A Mathematical Journey by Flannery, Sarah, with Flannery, David: Very good Hardcover (2001) First Printing [stated].
Box 8369, Silver Spring, MD 20907-8369. This was her first science fair, and her initial entry into the January 1998 Irish Young Scientist Exhibition received a first place in the Individual Intermediate Mathematics, Physics and Chemistry division. The class, which met Tuesday evenings from seven to ten, consisted of eight people and ran for twenty-five nights. She gives the reader to skip the really mathematical chapters which arent' necessary for enjoying the book. This is true even if the title states it includes any access cards, study guides, lab manuals, CDs, etc. I walked a middle ground in that I read a large portion of the math stuff, but I did hit a wall where I finally decided to move along to the narrative.
Originally published in England and cowritten with her mathematician father, David Flannery, IN CODE is "a wonderfully moving story about the thrill of the mathematical chase" Nature and "a paean to intellectual adventure" Times Educational Supplement. So she entered the equivalent of a science fair with her project on RSA Public Key Cryptography. Beyond the above, I am better able to practice my trade as a result of reading this book; that very seldom happens. From the Inside Flap: From puzzles on the blackboard in an Irish country kitchen to her acclaimed Cayley-Purser algorithm, Sarah Flannery has made an extraordinary beginning as a mathematician. As part of her transition year, Sarah was given the opportunity to work in industry for two weeks. .
In Code: A Mathematical Journey by David Flannery, Sarah Flannery (9781565123779)
She grew up in the shadow of Blarney Castle, she and her four brothers raised by an independent-thinking pair of parents. At its simplest level, this book is the story of Sarah Flannery, an Irish girl, who at the age of 15 was talked by one of her teachers into entering the annual national science fair to be held in Dublin a few months later, in January. Simon Singh, author of Fermat's Enigma and The Code Book" "A veritable mathematical travelogue. Overall, I highly recommend this book to everyone who has any appreciation for a good puzzle. It is unusually well written for any book and exceptionally so for its genre.
It's a good example of how parental involvement in education, and not just sending the kids to school, can help the kids immensely. I highly recommend this book. The first third of the book illustrates Sarah's upbringing by her mathematician dad and down to earth family, and she provides several fun mathematical puzzles. At meals, the blackboard would be the focal point for discussion of puzzles. She tells about her interactions with the judges for the competition, and the pressures that eventually resulted in her winning a silver trophy, a cash prize, fame, travel, and interactions with the media.
At 16, Flannery made worldwide headlines as Ireland's 1999 Young Scientist of the Year for her discovery and presentation of the Cayley-Purser algorithm, an innovative encryption system roughly 22 times faster than the worldwide standard RSA algorithm. I highly recommend this book. She has that great ingenuity and enthusiasm that justify the belief that great work is done before 25 years old, and also the idea that teenagers should be involved in way more complex and challenging stuff compared to what we feed them nowadays. Her father suggested she enter a mathematics project that investigated cryptography. Dad told us at the outset that there would be no pressure to perform, and that we need not fear being asked questions but we could ask them at any time.
In code : a mathematical journey : Flannery, Sarah, 1982
I did find the actual mathematical parts to be intriguing and, for the most part, well-explained. Flannery won two major science competitions in the late 1990s, and this book is her and her father's account of how that happened. A memoir in mathematics, it is all about how a girl next door, nurtured by her family, moved from the simple math puzzles that were the staple of dinnertime conversation to prime numbers, the Sieve of Eratosthenes, Fermat's Little Theorem, googols-and finally into her breathtaking algorithm. It wasn't until the 1960s that engineers and scientists began to find applications of number theory, and by the end of the 1970s the discipline came of age, in the applied sense, with the advent of public key cryptography very briefly, a modern form of cryptography which makes it possible to make public the method by which messages are enciphered, but-amazingly-without revealing how these enciphered messages are deciphered. I found Sarah's personal experiences with the science contests more interesting, and I'd highly recommend this book to any young person with an aptitude in math or science. The book is about the development of mathematical passion and excellence. In the beginning chapters, she offers the reader a selection of those brainteasers, many of which depend on mathematical reasoning.
I await the next book hopefully written by her Dad on mathematical puzzles. And I got it. To say nothing of the admirable human experience interspaced with the more intellectual stuff. Not being one who is familiar with crytography per se but an amateurish afficionado of Number Theory, I found her explanations of the pertinent mathematics charming, refreshing and stimulating. She encountered setbacks and frustrations and came across as a very normal person.
