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.

## First-years: Don’t fall in love, according to math

The William Lowell Putnam Mathematical Competition is the preeminent mathematics competition for undergraduate college students in the United States and Canada. The Putnam Competition takes place annually on the first Saturday of December. The competition consists of two 3-hour sessions, one in the morning and one in the afternoon. During each session, participants work individually on 6 challenging mathematical problems.

The Putnam began in as a competition between mathematics departments at colleges and universities.

For first-years at Duke, stress comes in various forms: making friends, struggling in class, missing the bus. For many of these novel pressures, Duke attempts to provide some feeble remediation. But for perhaps the most stressful of all—finding love—even Duke can provide no help. From first-year move-in to commencement, you have around 1, days to find the best possible person to start your Duke romance with. But finding love, especially mathematically optimal love, is no small feat.

Settle down too early, and end up missing out on an even better future partner.

The long-sought-after solution could be used to accurately predict encounter and transmission probability between individuals in a closed environment, without the need for time-consuming computer simulations. In his paper, published in Physical Review X , Dr Luca Giuggioli from the Department of Engineering Mathematics at the University of Bristol describes how to analytically calculate the probability of occupation in discrete time and discrete space of a diffusing particle or entity in a confined space — something that until now was only possible computationally.

Dr Giuggioli said: “The diffusion equation models random movement and is one of the fundamental equations of physics. The analytic solution of the diffusion equation in finite domains, when time and space is continuous, has been known for a long time. The finding has far-reaching implications across a range of disciplines and possible applications include predicting molecules diffusing inside cells, bacteria roaming in a petri dish, animals foraging within their home ranges, or robots searching in a disaster area.

Solving the conundrum involved the joint use of two techniques: special mathematical functions known as Chebyshev polynomials, and a technique invented to tackle electrostatic problems, the so-called method of images. This approach allowed Dr Giuggioli to construct hierarchically the solution to the discrete diffusion equation in higher dimension from the one in lower dimensions.

Sections: Log-based word problems , exponential-based word problems. Since the decay rate is given in terms of minutes, then time t will be in minutes. However, I note that there is no beginning or ending amount given. How am I supposed to figure out what the decay constant is? I can do this by working from the definition of “half-life”: in the given amount of time in this case, 9. Since the half-life does not depend on how much I started with, I can either pick an arbitrary beginning amount such as grams and then calculate the decay constant after 9.

More recently, a plethora of market-minded dating books are one problem with the market metaphor; another is that dating is not a one-time transaction. human loneliness or desire that makes them keep doing the math.

The secretary problem is a problem that demonstrates a scenario involving optimal stopping theory. It is also known as the marriage problem , the sultan’s dowry problem , the fussy suitor problem , the googol game , and the best choice problem. The applicants are interviewed one by one in random order. A decision about each particular applicant is to be made immediately after the interview. Once rejected, an applicant cannot be recalled.

During the interview, the administrator gains information sufficient to rank the applicant among all applicants interviewed so far, but is unaware of the quality of yet unseen applicants. The question is about the optimal strategy stopping rule to maximize the probability of selecting the best applicant. If the decision can be deferred to the end, this can be solved by the simple maximum selection algorithm of tracking the running maximum and who achieved it , and selecting the overall maximum at the end.

The difficulty is that the decision must be made immediately. The shortest rigorous proof known so far is provided by the odds algorithm Bruss A candidate is defined as an applicant who, when interviewed, is better than all the applicants interviewed previously. Skip is used to mean “reject immediately after the interview”. Since the objective in the problem is to select the single best applicant, only candidates will be considered for acceptance.

Math Kangaroo is an international mathematical competition for students in grades 1 through The competition consists of a single round that is taken on the same date third Thursday of March at a registered center. Awards are given to the top scoring students per grade at the national level. High scoring students in the US that are ranked high within their state will also be awarded as a state winner. Any student that is currently enrolled in grades 1 through 12 or homeschooled equivalent is eligible to participate.

They must register to a center several months prior to the testing date and pay a small participation fee. After the registration deadline students may still compete, but the fee increases and does not guarantee a spot. Students must take the contest at the registered center. The center they register does not have to be in their home state or country, so competitors often register for a testing site that is the closest or most convenient for them despite being outside of the state.

Competitors will automatically be placed in a specific level according to their grades.

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.

When it comes to love, making long-term decisions is a risky business. Sooner or later, most of us decide to leave our carefree bachelor or bachelorette days behind us and settle down. Just ask anyone who has found themselves stung by the eligible bachelor paradox. If you decided never to settle down, you could sit back at the end of your life and list everyone you ever dated, with the luxury of being able to score each one on how good they could have been as your life partner.

Such a list would be pretty pointless by then, but if only you could have it earlier, it would make choosing a life partner a fair sight easier. But the big question is, how can you select the best person on your imaginary list to settle down with, without knowing any of the information that lies ahead of you?

In this section we will explore the use of carbon dating to determine the age of fossil remains. Carbon is a key element in biologically important molecules. During the lifetime of an organism, carbon is brought into the cell from the environment in the form of either carbon dioxide or carbon-based food molecules such as glucose; then used to build biologically important molecules such as sugars, proteins, fats, and nucleic acids.

These molecules are subsequently incorporated into the cells and tissues that make up living things. Therefore, organisms from a single-celled bacteria to the largest of the dinosaurs leave behind carbon-based remains. Carbon dating is based upon the decay of 14 C, a radioactive isotope of carbon with a relatively long half-life years. While 12 C is the most abundant carbon isotope, there is a close to constant ratio of 12 C to 14 C in the environment, and hence in the molecules, cells, and tissues of living organisms.

This constant ratio is maintained until the death of an organism, when 14 C stops being replenished.
