Geek’s Questions: The Art of Asking Yourself

A+Click contributor Gerry Geek just published a new true story: Image

A group of friends visit me. They eat and drink everything, even the cat’s food, and then leave. The fridge is empty – only a glass of milk is left. I give half of the milk to my cat Ben. He drinks half of it and then I drink half of what is left. Again, he drinks half of what is left and then I do the same. We continue until nothing is left. What proportion of the initial amount of milk did I drink in total?

I remember the moment when I saw Jane for the first time. We were sitting at the same table at a tea room along with Mary and John. We looked at each other and I was sure that everybody immediately chooses another. If two boys and two girls choose a partner, then what is the probability that everybody chooses the person who chooses them?

Before I met Jane I had a relationship with three girls who lived in the same house. I sent three letters to them. If the postman put the letters into three different boxes without looking at the name of the recipient, what would be the probability that all girls received their letters?

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

A Nice “Feel Good” Story In Two Parts

Part 1  Comes From Ohio, USA

found at   protecher.net

numbers“Someone on here posted a math website that had math activities for grades 1 – 12, called A+ Click.

Anyway, I passed it along to my husband, who teaches math ~ who is addicted to math. My husband got on the doggone thing ~ and stayed for weeks. It’s so like him ~ anything with computers and math has got to be good!

Sadly, there were a few “glitches” in some of the answers ~ which only a math nut like my husband would ever notice! After that, he was on that website every night, scouring for ways to tweak it. (I never got back on the thread to mention this ~ I just didn’t have the heart to put cold water on it…)

Well, each time my husband found something ~ he would politely email the creator, who came to welcome my husband’s input. This went on for several weeks ~ by now, I think my husband spent so much time on the website that he’s seen every problem ever invented! So, today, I guess my husband found, in his school mailbox, a letter from the creator (who lives in Europe) thanking him so nicely ~ and a big, glossy book on Switzerland, with gorgeous picture after gorgeous picture in it!!! Wow!

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!”
