81 digits of $\pi$ as a forest of trees: standard, bat cave and underwater editions. ( BUY ARTWORK )
The 2021 Pi Day art celebrates the digits of $\pi$ with a forest! Visit the bat cave and underwater ecosystems for the full experience.

2019 $\pi$ has hundreds of digits, hundreds of languages and a special kids' edition.

Circular $\pi$ art and other distractions

On March 14th celebrate $\pi$ Day. Hug $\pi$—find a way to do it.

For those who favour $\tau=2\pi$ will have to postpone celebrations until July 26th. That's what you get for thinking that $\pi$ is wrong. I sympathize with this position and have $\tau$ day art too!

If you're not into details, you may opt to party on July 22nd, which is $\pi$ approximation day ($\pi$ ≈ 22/7). It's 20% more accurate that the official $\pi$ day!

Finally, if you believe that $\pi = 3$, you should read why $\pi$ is not equal to 3.

Most of the art is available for purchase as framed prints and, yes, even pillows. Sleep's never been more important — I take custom requests.
3 Little $\pi$,
1 what
4 can you tell us?

Welcome to this year's celebration of $\pi$ and mathematics. Among the chaos of CORVID-19, this year $\pi$ Day celebrations are short poetic emissions I call “piku” . They are brief pauses for the time.

Start by reading how piku are constructed and then browse submitted piku. Consider participating by submitting your own piku. All you need is a pen and a few (small) words. Very therapeutic.

But if the words here don't help, immerse yourself in my coronavirus art. It's quite catching.

If you enjoy poetry and words, see how I convert spam into poems in the style of ee cummings and if you like to see words arrange on page, look through my typographic art.

Here are some ideas and exercises to incorporate into your classroom, family dinner, or first date.

## activity 1

Next time you buy something, look at the total amount on the bill and write an nku corresponding to the amount about how your purchase makes you feel. For example, if you spent \$13.25 write an nku for $n=1325$.

1 This
3 object will
2 no doubt
5 make my life better.

After one week, write another nku about the object but this time make it into a message for someone whose is considering making the same purchase.

1 Life:
3 not better,
2 not worse.
5 No dream is no change.

## activity 2

Have everyone write a piku in 60 seconds. They may write as many lines as they want.

Once everyone is finished, have them pass their piku to the person next to them to read outloud.

## activity 3

Divide the digits of $\pi$ into triplets and assign everyone in the group a different triplet.

Have them write a nku for that triplet. Make a single piku by assembling the nkus according to the order of the triplets.

For example, if you have three people you would assign the triplets 314, 159, 265.

For continuity, have everyone incorporate a given word in their nku or make their nku about have a specific theme.

## activity 4

Have everyone write their birth date in DDMMYYYY format and create an nku for the number.

Remember zeros are lines with zero syllables and act as verse separators.

## activity 5

Create a calendar by writing a different nku for each day/month combination (DDMM) in the year. Assemble these in a stack.

For example, for March 14th, the digit is 1403 and one possible nku is

1 Dust
4 in space vacuum
0
3 makes trouble.

This is a long-term project.

# Music for the Moon: Flunk's 'Down Here / Moon Above'

Sat 29-05-2021

The Sanctuary Project is a Lunar vault of science and art. It includes two fully sequenced human genomes, sequenced and assembled by us at Canada's Michael Smith Genome Sciences Centre.

The first disc includes a song composed by Flunk for the (eventual) trip to the Moon.

But how do you send sound to space? I describe the inspiration, process and art behind the work.

The song 'Down Here / Moon Above' from Flunk's new album History of Everything Ever is our song for space. It appears on the Sanctuary genome discs, which aim to send two fully sequenced human genomes to the Moon. (more)

# Happy 2021 $\pi$ Day—A forest of digits

Sun 14-03-2021

Celebrate $\pi$ Day (March 14th) and finally see the digits through the forest.

The 26th tree in the digit forest of $\pi$. Why is there a flower on the ground?. (details)

This year is full of botanical whimsy. A Lindenmayer system forest – deterministic but always changing. Feel free to stop and pick the flowers from the ground.

The first 46 digits of $\pi$ in 8 trees. There are so many more. (details)

And things can get crazy in the forest.

A forest of the digits of '\pi$, by ecosystem. (details) Check out art from previous years: 2013$\pi$Day and 2014$\pi$Day, 2015$\pi$Day, 2016$\pi$Day, 2017$\pi$Day, 2018$\pi$Day and 2019$\pi` Day.

# Testing for rare conditions

Sun 30-05-2021

All that glitters is not gold. —W. Shakespeare

The sensitivity and specificity of a test do not necessarily correspond to its error rate. This becomes critically important when testing for a rare condition — a test with 99% sensitivity and specificity has an even chance of being wrong when the condition prevalence is 1%.

We discuss the positive predictive value (PPV) and how practices such as screen can increase it.

# Standardization fallacy

Tue 09-02-2021

We demand rigidly defined areas of doubt and uncertainty! —D. Adams

A popular notion about experiments is that it's good to keep variability in subjects low to limit the influence of confounding factors. This is called standardization.

Unfortunately, although standardization increases power, it can induce unrealistically low variability and lead to results that do not generalize to the population of interest. And, in fact, may be irreproducible.

Nature Methods Points of Significance column: Standardization fallacy. (read)

Not paying attention to these details and thinking (or hoping) that standardization is always good is the "standardization fallacy". In this column, we look at how standardization can be balanced with heterogenization to avoid this thorny issue.
