The Jiuzhang suanshu or Nine Chapters on the Mathematical Art is a practical handbook of mathematics consisting of problems intended to provide methods to be used to solve everyday problems of engineering, surveying, trade, and taxation. It has played a fundamental role in the development of mathematics in China, not dissimilar to the role of Euclid ‘s Elements in the mathematics which developed from the foundations set up by the ancient Greeks. There is one major difference which we must examine right at the start of this article and this is the concept of proof. It is well known what that Euclid , for example, gives rigorous proofs of his results. Failure to see similar rigorous proofs in Chinese works such as the Nine Chapters on the Mathematical Art led to historians believing that the Chinese gave formulas without justification. This however is simply an example of historians well versed in mathematics which is essentially derived from Greek mathematics, thinking that Chinese mathematics was inferior since it was different. Recent work has begun to correct this false impression and understand that there are different understandings of “proof”.

When James Maynard was three, a health visitor came to his home in Chelmsford, just northeast of London, to check on his development. Such visits were routine for young children, and the assessor led him through a standard battery of tests. There was just one problem: Maynard thought they were stupid. So when she gave him a shape-sorting task, he intentionally put the shapes in a surprising order, then explained at length why his solution was more interesting than hers.

When he decided the assessment had gone on long enough, he declared it finished and pulled out his Legos. The assessor told his mother that James lacked discipline.

More recently, a plethora of market-minded dating books are coaching singles on how to seal a romantic deal, and dating apps, which have rapidly become the mode du jour for single people to meet each other, make sex and romance even more like shopping. The idea that a population of single people can be analyzed like a market might be useful to some extent to sociologists or economists, but the widespread adoption of it by single people themselves can result in a warped outlook on love.

M oira Weigel , the author of Labor of Love: The Invention of Dating , argues that dating as we know it—single people going out together to restaurants, bars, movies, and other commercial or semicommercial spaces—came about in the late 19th century. What dating does is it takes that process out of the home, out of supervised and mostly noncommercial spaces, to movie theaters and dance halls.

The application of the supply-and-demand concept, Weigel said, may have come into the picture in the late 19th century, when American cities were exploding in population. Read: The rise of dating-app fatigue.

The Pascal, Cayley and Fermat Contests are an opportunity for students to have fun and to develop their mathematical problem solving ability. Students in Grade 9 or below are eligible to write the Pascal Contest. Students in Grade 10 or below are eligible to write the Cayley Contest. Students in Grade 11 or below are eligible to write the Fermat Contest.

Early questions require only concepts found in the curriculum common to all provinces. The last few questions are designed to test ingenuity and insight. Rather than testing content, most of the contest problems test logical thinking and mathematical problem solving. Schools can register for contests online by the deadline. View fees. Schools that have not registered for previous contests are encouraged to participate, and can start by filling out a New School Application form.

We recommend that students spend some time preparing for our contests by trying to solve problems. Many teachers use past contests in the classroom and the CEMC problem set generator allows anyone to create random sets of problems with the option to customize the topics covered. Results booklets Pascal , Cayley , Fermat and averages and cutoffs are online.

## MI Mathematics Prize Competition

Each year on the first Saturday in December, several thousand US and Canadian students spend 6 hours in two sittings trying to solve 12 problems. Individual and team winners and their schools, in the latter case get some money and a few minutes of fame. Problem statements given here are verbatim from the competition except some diagrams are missing , and are copyrighted by the MAA.

Google Lens will include a ‘Homework’ filter that solves math problems using an app called Socratic. Google is using technology from a mobile learning app called Socratic — which the company acquired in — to run the forthcoming Lens feature, solving homework problems with nothing but a picture of the equation, according to a recent blog post on Google’s website. The rollout date for Google Lens has yet to be announced, but the underlying Socratic feature is already live and available for iOS and Android users.

Google has offered students and parents more tools to make homeschooling and studying easier. In May of this year, it launched a feature within Search based on augmented reality that lets users see 3D anatomy models, in addition to cellular structures. Soon, the colossal tech giant will help everyone solve math problems with nothing more than a photo taken via Google Lens, reports Engadget.

Once Google Lens goes live, users will snap a pic of their study material, highlight a troublesome equation or complex problem to access step-by-step guides with meticulous explainers. The aim is to make looking up mathematical concepts as easy as possible, since applying concepts and formulas comes only after understanding them. Google has yet to say when the Lens feature will go live, but Socratic is already available for download on Android and iOS. For example, search “Quantum mechanical model,” and users will see a 3D atom model superimposed on one’s environment.

Google’s Director of Program Management for Education Jennifer Holland also mentioned other tools capable of helping students who are now compulsory homebodies due to the coronavirus crisis. She spoke about Read Along, a feature designed to inspire or enhance kids’ interest in reading. Additionally, the live caption and smart speaker feature of Google Meet ‘s — called Family Bell — keeps students and possibly teachers on schedule with timed announcements to remind them when it’s time to begin online classes, or give our minds a well-deserved break.

We hope to resume in person meetings again as soon as we are able. We will post updates to our web site and to our email list. We will also post our plans to our schedule page! Abstract: We’ll discuss the idea of Turing machines, which is the fancy name for computers when we want to think about them by using math. Using this, we’ll be able to talk about why we can prove there are some things that computers will never ever be able to do! For more information and registration, click here!

Abstract: We’re going to talk about an awesome pattern that comes up in geometry, called Pick’s Theorem. Pick’s Theorem says there is an awesome relationship between the area of certain shapes, called lattice polygons. We’ll talk about what these shapes are and what pattern of their area is! Abstract: In the intermediate room, we’ll talk about a really interesting problem that comes from probability theory, called the Monty Hall problem. This is a math problem that you don’t need any algebra to explain what is going on, but yet many famous math professors got WRONG.

We’ll talk about what this problem says and related problems in probability. Note: Starting this session, we’ll be breaking into the lectures into two rooms–the intermediate room or the advanced room–based on what kind of math class you are in!

## Putnam Competition

This section begins with a discussion of exponential growth and decay, which you have probably already seen in calculus. We consider applications to radioactive decay, carbon dating, and compound interest. We also consider more complicated problems where the rate of change of a quantity is in part proportional to the magnitude of the quantity, but is also influenced by other other factors for example, a radioactive substance is manufactured at a certain rate, but decays at a rate proportional to its mass, or a saver makes regular deposits in a savings account that draws compound interest.

Experimental evidence shows that radioactive material decays at a rate proportional to the mass of the material present. A radioactive substance has a half-life of years. Thus, increasing the frequency of compounding increases the value of the account after a fixed period of time.

The first example deals with radiocarbon dating. The concept is kind of simple:. Every living being exchanges the chemical element carbon during its entire live. But carbon is not carbon. It consists almost on Carbon the stable nuclide but to a certain amount on Carbon, too. In nature the ratio is approximately constant due to a continuous production of in the earth atmosphere by cosmic rays. This production compensates the decay.

And therefore the ratio in living beings will be the same like the one of the earth atmosphere since our metabolism is taking in carbon of that particular ratio at any time. Until we die. And here comes the decay handy: With the death of an organism no more is replaced. And if we know the decay-function the function that describes the time dependency of the decay we can determine how long ago this organism died — means we can determine its age!

What is left is to determine the value of k.
