I was recently featured on a podcast called Alone Together. This podcast is all about the meaning of loneliness as inspired by the pandemic. You see, there was a psychologist who studied the physiological impact of loneliness on the mind and body. It can be surprisingly damaging. I was super psyched to be interviewed for an episode on mathematics.

I was very pleased with how everything turned out but I do have one regret. Insisting that the beauty of mathematics lies in its truth. That is a very romantic thought and it sounds great as a quote. But this is a naive and idealist perspective. Mathematics is still subject to bias. It can be political. People make real decisions about who or who not to study. What mathematical perspectives matter. etc.

So, I want to say sorry for presenting such a view to listeners who may not be so involved with mathematics. If you want to understand the issues that I’m talking about you cannot do better than this Twitter thread from Michole Enjoli.

Please follow Michole Enjoli on Twitter. Well worth it!

]]>Today is a special day of the India yearly calendar. It marks the celebration of mathematics in that country. It also marks the anniversary of the birth of Srinivasa Ramanujan.

Ramanujan was a genius mathematician who was obsessed with mathematics his whole life. He was largely self-taught. He kept notebooks where he performed investigations and found some solutions re-discovered and new.

He saw math in his dreams and believed them to be from his Goddess Mahalakshmi of Namakkal.

Learning this about Ramanujan made me feel a little closer to him. I also have math dreams. I can never predict when they will come but they are so immersive. I cannot explain what it is like to view the world from the position of being a graph. Something impossible to experience in the real world but very possible in dreams.

The other connection that I have is the mathematician G.H. Hardy. To pursue his dreams, Ramanujan wrote to many people at Cambridge. Hardy was the first to recognize he was dealing with a mathematical genius and brought him to the UK. Together they did profound work and it is one of the most celebrated partnerships in math history.

You can read Ramanujan’s story in the book, “The Man Who Knew Infinity.” This was also translated to screen by the same title starring Jeremy Irons as Hardy and Dev Petal as Ramanujan.

By the way, I have a pattern for the Taxicab number if you wish to sew it as a bookmark.

Taxicab Number (329 downloads)National Mathematics Day was first celebrated on December 22^{nd}, 2012. It was declared a holiday in India for the 125th anniversary of Srinivasa Ramanujan’s birth. In 2017, the Ramanujan Math Park was opened. Similar to our MoMath full of interactive learning.

This stamp was issued to commemorate the first National Mathematics Day.

My father passed away a few years back. He started collecting stamps when he was very young. His mother wanted him to start the hobby to learn geography. I remembered him sharing his albums with me when I was growing up.

I asked my step-mother to send me his collection if she ever found it. I did not know how extensive it was. This year she mailed me three boxes worth of stamps and coins.

My father and I weren’t close. We didn’t see eye to eye on most things though we did love each other. Things got better in my later years as we started to reach a mutual understanding. Unfortunately, I was never really able to repair our relationship as time ran out for us.

This stamp collection is one connection that I still have with my dad. So it felt right to add to the collection and make it ours. That’s how I came to purchase three different stamps from India on ebay that all celebrate Ramanujan including this National Mathematics Day stamp. Finally something we can do together.

]]>My cross stitch designs started with 15 mathematical pieces published on April 1st, no joke. They were a stockpile of bookmarks that came from my imagination. A way to celebrate maths through one of my favorite hobbies. I’ve used these designs effectively in my mathematics advocacy work.

Later this year, I published three more cross stitch patterns to that collection. Including one for the taxicab number, celebrating the friendship of G.H Hardy and Ramanujan. I’ll have more on Ramanujan in an upcoming blog post for India’s National Mathematics Day (That’s December 22nd.)

There were some mathematical cross stitch patterns that I was unhappy with and have since update their design.

This is the trifecta of irrational numbers. I am completely memorized by e. It is by far my favorite constant and transcendental number. I know many people feel this way about pi. I added the golden ration to the mix (phi) for good measure. As I am sure it has its own fans.

I changed two things:

- Each symbol is now rendered in a similar way over its own digits.
- I’ve made Dark Royal Blue (DMC 796) my default color for patterns.

That being said, you can use whichever colors you want. I leave that at the discretion of the maker.

This pattern is meant specifically to be worked on 14 count black aida cloth. The change to this cross stitch pattern is in the diagram. For whatever reason, the program I use doesn’t print patterns with a black background. So instead I had to make this readable on a white background. When you download the PDF just know that DMC 310 represents white thread. The completed pattern should look like the image below.

Enigma (Alan Turing) (448 downloads)I simply wanted to show the randomness of pi and e by doing a simple data visualization. Replacing the digits with 10 x 10 blocks of color. The original colors were random and uncoordinated. I never liked that look. I’ve converted them all to contrasting blue hues.

Not much has changed here just converted that default color to the Dark Royal Blue.

Dozenal or Base 12 (426 downloads)Look out, because I’ll some more coming up in the new year that are calculus based. This includes my favorite the Fundamental Theorems of Calculus. If you haven’t guess by my tattoo my favorite math is integrals. It is about time that I got around to them.
