Google Lens Announces New ‘Homework’ Filter, Solves Math Problems With Photo

Are you stumped by the dating game? Never fear — Plus is here! In this article we’ll look at one of the central questions of dating: how many people should you date before settling for something a little more serious? Why is that a good strategy? You don’t want to go for the very first person who comes along, even if they are great, because someone better might turn up later. On the other hand, you don’t want to be too choosy: once you have rejected someone, you most likely won’t get them back.

When should you settle down?

Subscriber Account active since. At that point in a selection process, you’ll have gathered enough information to make an informed decision, but you won’t have wasted too much time looking at more options than necessary. A common thought experiment to demonstrate this theory — developed by non-PC math guys in the s — is called “The Secretary Problem.

In the hypothetical scenario, you can only screen secretaries once.

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.

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.

The third was engaged to a man — definitely a problem. say, you live in a small town and there aren’t unlimited men to date, garages to go.

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.

A physicist has developed an online tool to help you calculate your chances of falling in love. It’s based on the “Optimal Stopping problem.”.

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? When dating is framed in this way, an area of mathematics called optimal stopping theory can offer the best possible strategy in your hunt for The One.

But optimal stopping theory goes further.

Nine Chapters on the Mathematical Art

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.

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.

St. Ives Problem

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.

Robert Krulwich. Poor Johannes Kepler. One of the greatest astronomers ever, the man who figured out the laws of planetary motion, a genius, scholar and mathematician — in , he needed a wife. The previous Mrs. Kepler had died of Hungarian spotted fever, so, with kids to raise and a household to manage, he decided to line up some candidates — but it wasn’t going very well. Being an orderly man, he decided to interview 11 women.

It’s a catalog of small disappointments. The first candidate, he wrote, had “stinking breath. The second “had been brought up in luxury that was above her station” — she had expensive tastes. Not promising. The third was engaged to a man — definitely a problem. Plus, that man had sired a child with a prostitute.

Mathematics , the science of structure, order, and relation that has evolved from elemental practices of counting, measuring, and describing the shapes of objects. It deals with logical reasoning and quantitative calculation, and its development has involved an increasing degree of idealization and abstraction of its subject matter. Since the 17th century, mathematics has been an indispensable adjunct to the physical sciences and technology, and in more recent times it has assumed a similar role in the quantitative aspects of the life sciences.

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.

Below are some Ice-Out tidbits that I have researched or learned from some reputable local sources — most notably Mama Koob, when she and a group of her wonderful friends educated me on one of my first cruises aboard our Oquossoc Lady back in ! Where do these dates come from? When is Ice-Out officially determined? RR was extended from Bemis to the southwest corner of Rangeley Lake.

All this said, it sounds like a reasonable explanation as to when Ice-Out is determined. It still boggles my mind that the beautiful steamer Rangeley puffed her way along the waters of Rangeley Lake! Who determines Ice-Out? So, my last question — actually a math problem. Grab the Rangeley phonebook, use a starting date of April 14th and an ending date of May, 24th, take the Ice-Out dates listed for through and calculate the historic Arithmetic Average mean date for Ice-Out.

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!

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. For example, someone in grade 5 will be placed in level 5. The test is 75 minutes long and consists of a series of multiple choice questions.
