Liar’s Math

Aplusclick Pinocchio

Pinocchio lies

When Pinocchio lies, his nose gets twice as long. When he tells the truth, his nose gets 1 cm shorter.

Today, his nose was 1 cm long in the morning, and it is 100 cm long in the evening.

What is the least possible number of times he opened his mouth today?

True and Random

Two gods  are called True and Random. True always speaks truly and Random speaks randomly truly or falsely. You don’t know who is who.

Determine the identities of the gods by asking yes-no questions; each question must be put to exactly one god.aplusclickgods

Pancake Math

panecake2“Archaeological evidence suggests that pancakes are probably the earliest and most widespread cereal food eaten in prehistoric societies.” – Wikipedia

 

What is the maximum number of sections into which a pancake may be divided into by four straight cuts through it?

Here more difficult questions go:

1) Is it possible to divided it so that all sections have equal area?

2) How many pancakes are needed to reach your height if they are squeezed by the weight of the upper pancakes?

3) If I spent 30 grams of batter for a pancake (French-style crêpe) of 30 cm in diameter how much batter do I need for the square pancake of the same thickness and the side length of 30 cm?  

 

These and many other practical “pancake” questions are presented in the Applied Math section of A+Click series, which already includes more than 4500 questions.

 

What is a puzzle?

“A puzzle is a problem that is fun to solve and has a right answer.” – Scott Kim, Puzzlemaster

What motivates us to work hard?

ImageMotivation theories can be very complex. This story is simpler than the reward analysis given in Dan Pink’s TED talk. Let’s look at a simple model of individual motivation at work, which can be presented as a MMM model:

  • M1: Myself:  I do it my way.
  • M2: Mastering:  I always improve what I do.
  • M3: Mission: I do it for a compelling purpose.

M1: Myself

Whatever I do I try to do it my way. This is valid for children and adults. We are all the same. It’s valid for work, leisure, and study. People often distress about purposelessness of their work. Doing own way is the first motivation factor for people who don’t find a potential at their main job and develop open source products like UNIX or Moodle.

M2 Mastering

Once we successfully produce something in our own manner, we constantly introduce improvements. We master our art and become craftsmen. The term ‘craftsman’ is not only related to “a skilled manual worker who makes items,“ it’s also related to teachers, software engineers, and all other professionals. It takes time to become a craftsman.

M3 Mission

A craftsman never ceases striving to master his arts, continuing to work for a purpose. In the book Craftsman, Richard Sennet said: “the craftsman is special because he or she is an engaged human being”. This stage corresponds to the highest level of the Maslow’s hierarchy of needs. Human beings are “social beings” who work together and learn by looking at how others work. Thus, we create our masterpieces for others. The purpose of creating and giving to others is at the top of the motivation pyramid.

Here is an example:

When I was a young boy, I studied mathematics in school and also on my own using Martin Gardner’s puzzles books. I often walked several miles to the city library in chilly Siberian frost to read just a few of the puzzle books’ pages. Very soon, I missed compelling challenges.

Now, as an adult, I am eager to help children throughout the world who are in the same position that I was in as a child to discover interesting, practical, and challenging math and logic puzzles and answers. We created a collection of more than 2200 compelling problems at http://www.aplusclick.com.

How the project was developed?

M1  Myself

At the beginning it was just a desire to challenge myself with logic puzzles and to present them in Internet. I saw many collections. What dissatisfied me? Existing solutions were concentrated on a specific type of problems and user age. Many of them were boring. It was difficult to fast find what I looked for. I do it in MY OWN way. I decide to improve our users’ experience according to the KISS approach: Keep It Simple and Stupid. These puzzles are illustrated, short, simple, and interesting for all ages. No sign up, no fees, and no advertising. Steve Jobs’ obsession with the customer’s experience was an inspiration for me.

M2 Mastering

After first months of exposing the set of problems, we receive feedback, suggestions for improving. It motivates us to improve the quality, to add interesting illustrations. We started to MASTERING our craft. So the number of puzzles grows to 2200 in two years and the new puzzles became more interesting.

M3 Mission

Now we continue working for a compelling PURPOSE. I always say WE, because dozens of people worldwide have helped us develop this library of math and logic problems. They thoroughly reviewed the problems and helped to make them simple and clear. Here a testimonial is:

“Strangers reaching out to one another, across great distances, just because of common interests in learning and helping other learners ~ kind mutual exchanges like this give me hope for a better world!”

Everyday, thousands of children spend a great deal of time and effort mastering their logical reasoning and mathematical thinking at Aplusclick. We thank all of our users and contributors for such a marvelous initiative to help children grow intellectually and become problems solvers.

Conclusion

We often find ourselves on one of the steps of the MMM model. The higher the step, the higher the level of individual motivation. More detailed hierarchy of work motivation is given in the Work Motivation pyramid. KokcharovWorkMotivation2015
