Contemplations – Now

An appetizer:

I have approximate answers and possible beliefs and different degrees of certainty about different things. But I'm not absolutely sure of anything, and there are many things I don't know anything about, such as whether it means anything to ask why we're here, and what the question might mean. I might think about it a little bit; if I can't figure it out, then I go onto something else. But I don't have to know an answer. I don't feel frightened by not knowing things, by being lost in the mysterious universe without having any purpose, which is the way it really is, as far as I can tell—possibly. It doesn't frighten me.
– Richard Feynman. BBC interview with Feynman.

A Very Brief History of Mathematics

Cover art for A Very Brief History of Mathematics episode of The Stephen Wolfram Podcast

One of the things that's really great about mathematics is that once something is true in mathematics, it's true forever, and so the things that were established—often with very messy notation, back in 2,000 B.C.—are still true today, and we still teach them to kids today: the platonic solids, the icosahedra that you find from ancient Egypt, still look very modern because icosahedra are still the same as they ever were. It's a nice feature that while so much has changed in human society and the development of human knowledge, one of the things that remains identical is anything that was established in mathematics, even a very long time ago. So that a pretty neat feature—and a unique feature— of that field.

Tokyo subway’s humble duct-tape typographer

Duct tape sign by Shuetsu Sato

I love this story! Chris Gaul shares this wonderful story on Medium about a Tokyo subway security guard, Shuetsu Sato, who creates beautiful signage out of duct tape in order to help the people he takes care of find their way more easily.

Sixty-five year old Sato san wears a crisp canary yellow uniform, reflective vest and polished white helmet. His job is to guide rush hour commuters through confusing and hazardous construction areas. When Sato san realised he needed more than his megaphone to perform this duty, he took it upon himself to make some temporary signage. With a few rolls of of duct tape and a craft knife, he has elevated the humble worksite sign to an art form.

"Shinjuku Station was my first post, and it was under construction at the time, so I had to guide passengers using a megaphone. But there were so many people. Guiding them all with just my voice was impossible. Most of the people couldn’t even hear me. So I decided to make some signs to guide people that would really stand out."

Although he had no formal design training, he created an aesthetic grid system for his stylized lettering, which has become highly regarded by other designers, who have given it the name "Shuetsu Sans."

44 African Americans Who Shook Up the World

Stylized 44 from the article

Very interesting snapshots of the "44 Most Influential Black Americans in History." From the introduction:

This is a list of The Undefeated 44, a collection of dreamers and doers, noisy geniuses and quiet innovators, record-breakers and symbols of pride and aspiration.

The portraits by Robert Ball that illustrate the snapshots are amazing. The following image combines two of the portraits: Ida B. Wells⩘ , 1862 - 1931, a fearless journalist known as the "Sword Among Lions," and co-founder of the NAACP; and Frederick Douglass⩘ , 1818 - 1895, a leader of the abolitionist movement, fiery orator, writer, and statesman.

Warming Stripes for Colorado from 1895-2018

#ShowYourStripes

The Show Your Stripes website provides an interactive tool that creates temperature stripes for different areas of the world. The one for Colorado, the state where I live, confirms my experience of the change that is occurring.

Excerpts from their FAQ:

These 'warming stripe' graphics are visual representations of the change in temperature as measured in each country over the past 100+ years. Each stripe represents the temperature in that country averaged over a year. For most countries, the stripes start in the year 1901 and finish in 2018. For the UK, USA, Switzerland & Germany, the data starts in the late 19th century.

For virtually every country or region, the stripes turn from mainly blue to mainly red in more recent years, illustrating the rise in average temperatures in that country.

For most countries, the data comes from the Berkeley Earth temperature dataset, updated to the end of 2018. For some countries (USA, UK, Switzerland & Germany) the data comes from the relevant national meteorological agency. For each country, the average temperature in 1971 - 2000 is set as the boundary between blue and red colours, and the colour scale varies from +/- 2.6 standard deviations of the annual average temperatures between 1901-2000.

How language shapes the way we think

How language shapes the way we think by Lera Boroditsky, TEDWomen 2017

Lera Boroditsky, Associate professor of cognitive science at University of California San Diego, gave this interesting talk at TEDWomen 2017. I've watched it multiple times and have gotten more out of it each time.

Three ideas stand out for me. First, haw language can shape the way we organize time. English-speaking westerners tend to organize events on a time scale from left to right. But for the Kuuk Thaayorre people in Australia who speak Paman, a language rooted in cardinal directions, time is viewed as moving towards a person who is facing east, and away from a person who is facing west.

The second is how differently we may view events depending on our language, which is really worth keeping in mind as we attempt to communicate across cultures.

People who speak different languages pay attention to different things depending of what their language usually requires them to do. So we show the same accident to English speakers and Spanish speakers, English speakers will remember who did it because English requires you to say, "He did it; he broke the vase." Whereas Spanish speakers might be less likely to remember who did it, if it's an accident, but they're more likely to remember that it was an accident. They're more likely to remember the intention. So, two people watch the same event, witness the same crime, but end up remembering different things about that event. This has implications, of course, for eyewitness testimony. It also has implications for blame and punishment. So if you take English speakers and I just show you someone breaking a vase, and I say, "He broke the vase," as opposed to "The vase broke," even though you can witness it yourself, you can watch the video, you can watch the crime against the vase, you will punish someone more, you will blame someone more if I just said, "He broke it," as opposed to, "It broke." The language guides our reasoning about events.

Finally, there is this glimpse into the incredible gift of cognition.

Now, the beauty of linguistic diversity is that it reveals to us just how ingenious and how flexible the human mind is. Human minds have invented not one cognitive universe, but 7,000—there are 7,000 languages spoken around the world.

Photographing fungi

When I got a decent camera, I discovered that it helped me to see the world around me in a much more immersive manner; I began noticing things I might have walked right past previously, including fungi like this happy cluster that I noticed alongside the Buchanan Pass Trail.

Understanding this gift that photography gives me makes me even more deeply appreciate a set of photographs of fungi by Alison Pollack that I came across. She is fortunate to be in Northern California, which typically receives much more rainfall than we do here. The variety of fungi she has photographed, some of which are incredibly tiny and unlike anything I've seen before, is astonishing.

Is The Great Wave off Kanagawa a realistic depiction?

The Great Wave off Kanagawa by Katsushika Hokusai

The Great Wave off Kanagawa, a well-known woodblock print by Katsushika Hokusai, was first published sometime around 1830. The first print in his series Thirty-six Views of Mount Fuji, it depicts a giant wave breaking over three fishing boats off the coast near the town of Kanagawa.

Recently, a team of researchers at the Universities of Oxford and Edinburgh have been studying how these unexpected so-called "freak" or "rogue" waves can form. They have discovered that, under the right conditions, two sets of smaller waves intersecting at 120 degrees can result in these gigantic waves forming. Running tests in their wave pool, they even created a rogue wave very similar to Hokusai's Great Wave.

Like many people, I have been enjoying Hokusai's woodblock print for most of my life. But I had always presumed it was a highly stylized interpretation. How amazing it is to now learn that it is likely a realistic rendition of an actual, if incredible. natural phenomenon! My appreciation of the print has deepened.

From an article by Daniel Oberhaus in Motherboard⩘ , Jan 22 2019:

On New Year's day, 1995, the Draupner oil rig off the coast of Norway was experiencing some rough weather. According to a wave log kept at the station, the rig was pounded by 40-foot waves for most of the day, but shortly after 3 PM a single 80-foot wave appeared out of nowhere and slammed into the rig at 45 miles per hour.

Why forgetting may make your mind more efficient

Fascinating article about what recent research is revealing about the way the brain processes information.

Forgetfulness is not necessarily a sign of a faulty memory. "In fact," Wimber says, "it's been shown over and over in computational models and also in animal work that an intelligent memory system needs forgetting."

Whew!

Forgetting is essential, some researchers now argue, because the biological goal of the brain’s memory apparatus is not preserving information, but rather helping the brain make sound decisions.
