The moving sofa problem is inspired by the real-life issue of moving furniture around. A mathematician was probably carrying his sofa down a corridor. He had to navigate some obstacles and asked himself that question; what is the sofa of the largest area to move around the corner?


Paradoxes are statements that result in an inconsistency.

Consider these two examples:

“This statement is false,” & “I always tell lies.” These two statements cannot be true and false simultaneously. The reader is left in a conundrum.

  • If the statement is true, then it’s wrong because a statement is false.
  • If the statement is false, then that the statement must be true since the statement is false.

Thus a paradox results in a puzzling problem that cannot be resolved. With paradoxes, logic is sometimes defied. Other times it involves circular reasoning. And occasionally, the paradox results from an invalid argument. …


Who is Self? by Joe Anderson

How do you explain the deep interaction between philosophers and mathematicians throughout history?

In the history of human thought development, there has been constant interaction between philosophical and mathematical aspects. Many intellectual movements have sought their support, inspiration, and even their model in the style and way of mathematics. What could be the reasons for this approach?

Philosophers try to understand and unravel the many enigmas that the real world proposes to them. But the reality is too chaotic to try to address it as it is. …


One of the best-known features of Jupiter is the great red spot. It’s been there for hundreds of years, and it’s a big storm, a vast hurricane on Jupiter. And when the Voyager spacecraft got a look at that, it noticed you get complicated, turbulent vortices spinning off. What we see on Jupiter is turbulence. Big vortices, smaller vortices, tiny vortices, and if we could look closely — smaller and smaller and smaller ones.

Mathematics is something extraordinarily precise. Moreover, it is more accurate in different areas than in some areas we know less about it. People often find mathematics very abstract. But mathematics can describe reality as we understand it.

When we think about solid stuff like an umbrella scientifically, we picture molecules in our heads. We know molecules are made of atoms. Atoms are made out of nuclei and electrons going around. But what about the nucleus? What is an electron? At that stage, the best we can do is to describe some mathematical structure.

Mathematics describes things in the ordinary physical…


What is reality? Does reality exist? Is reality independent of the mind? How does a person find reality? What is “truth”? What does it mean to understand something truly? How does the brain come to understand something? How do we know if we understand something? What do we mean by “thinking”? How to can we get different conclusions from the same output? What is the proof?

If you don’t ask these and similar questions and are incapable of pondering the answers, you can not be considered an intellectual.

I am not saying that all intellectuals have to find reasonable answers…

We know that Kurt Gödel (1906–1978) worked intensively with Leibniz (1646–1716) towards the end of his life. Gödel was obsessed with Leibniz. When some people had destroyed some of Leibniz’s writings, Menger asked Gödel, “Who could have an interest in destroying Leibniz’s writings?” Gödel would say, “Naturally, those people who do not want men to become more intelligent!” (Menger, 1994). When his friends advised him to focus on his studies, he would ignore them rather than studying and reading Leibniz’s works. Eventually, the expected happened, and Gödel continued to follow Leibniz’s footsteps and gave God’s ontological proof like Leibniz.

Mathematics is a vast and diverse field, and so many good mathematicians can share their knowledge with humans in a beautiful way.

Although this year, 2020, has ruined our lives, it helped me read many math books this year. And now, I am eager to read some new good math books.

I have chosen 17 books for lifelong learners. I have read some of them this year and also I added the books that I am planning to read in 2021.

I hope you enjoy them.

Beyond Infinity: An Expedition to the Outer Limits of the Mathematical Universe — Eugenia Cheng

If infinity has always been a bit of an issue for you, this book…


In September 2013, the New York Times had an excellent op-ed piece entitled “How I Fell in Love With Math.” Unfortunately, I saw it today, and I got goosebumps because I have always loved math.

Every person is a product of his or her childhood experiences. I remember sitting in the back of a church when I was 12. I didn’t want to be there in the middle of the week. My parents allowed me to have my math book. If I could do the math, I would be happy.

Almost every math teachers love using movie clips about math in their classrooms to enhance content and engage their students. This listing is a sample of the types of movies that math people found useful.

Travelling Salesman

The movie is fantastic and quite good mathematically. It is a bit like the play by the Swiss writer Friedrich Dürrenmatt who wrote Die Physiker similarly discussing scientific ethics questions. A mysterious bodyguard is listening to all of the conversations (which is a bit strange, given that everything is so top secret). In Dürrenmatts’ play, there is a psychiatrist Mathilde von Zahnd who eavesdrops on…
