WTF Fun Fact 13226 – The Amazon Two Pizza Rule

by

One of the secrets of Jeff Bezos’ success may just be the Amazon Two Pizza rule.

What is the Amazon Two Pizza rule?

Amazon CEO Jeff Bezos apparently requires his senior executives to abide by a Two Pizza rule. Any team that can’t be fed with two pizzas is too big and should be broken into smaller teams. The rule ensures that teams include only essential members and that everyone stays focused on their specific area of expertise.

This rule encourages efficient and effective teamwork and ensures that communication remains open and clear.

Bezos believes in the importance of keeping teams small and nimble. He believes that small teams can move more quickly and make more efficient decisions. He also believes smaller teams are better equipped to communicate effectively. When a team is too big, communication breakdown can lead to delays and inefficiencies.

Bezos believes smaller teams are more focused. As a result, teams are more likely to work on the most important tasks and make the best use of their time. In the end, it’s all about preventing teams from becoming bogged down in tasks that are not relevant to their goals and allowing them to focus on delivering value to customers.

Small teams and success

Business leaders believe the Amazon Two-Pizza Rule helps foster innovation. Small teams ensure members are more likely to feel comfortable taking risks and trying new things.

In addition, by keeping teams small, managers and leaders get to know their team members. This helps them understand their strengths and weaknesses. This helps managers develop their skills in areas such as coaching and mentoring.

The purpose of pizzas

Amazon applies the Two Pizza rule in various forms, with teams ranging from two to a dozen people. It has been widely adopted by other companies.

By keeping teams small and focused, companies can ensure that they are able to work together effectively, deliver results quickly and foster innovation and creativity. — WTF fun facts

WTF Fun Fact 13225 – Emotions and the Stock Market

by

There is a connection between emotions and the stock market. In fact, the stock market can move dramatically even when the underlying fundamentals suggest it should move in the opposite direction.

What’s the connection between emotions and the stock market?

The stock market is driven by a variety of factors, including economic indicators, company performance, and investor sentiment. However, research has shown that emotions play a significant role in stock market behavior, and can often drive prices higher or lower regardless of the underlying fundamentals.

For example, studies have shown that stocks tend to perform better on sunny days, when investors are in a positive mood, and worse on cloudy days, when investors are in a negative mood. Similarly, stocks tend to perform better on days when there are more positive news articles, and worse on days when there are more negative news articles.

How does human behavior affect stock prices?

The stock market is often thought of as a rational, data-driven market, but emotions can have a major impact on prices and investment decisions. Investor sentiment can be just as important as financial data in determining stock prices.

When investors are feeling confident and optimistic, they tend to be more willing to take risks and invest. This, in turn, drives prices higher. When investors are feeling uncertain or fearful, they tend to pull back from the market, thereby causing prices to fall.

This emotional component of the stock market is particularly evident during times of economic uncertainty, such as recessions or market crashes, when investor sentiment can change rapidly and drive large swings in stock prices. In these situations, emotions like fear, panic, and greed can drive investor behavior and create market volatility.

While emotions can have a significant impact on the stock market, economic indicators, company performance, and macroeconomic factors such as interest rates, inflation, and political events play an integral role in determining stock prices.

Still, the emotional component of the stock market is a key factor to consider for investors. They need to be aware of how their own emotions and those of the market can impact their investment decisions.

WTF Fun Fact 13223 – The Benefits of Reading Physical Books

by

Reading is generally good for you, no matter how you do it (unless you’re falling down a rabbithole of conspiracy theories). And your body likes reading in any form. Still, research shows that the benefits of reading physical books is higher than reading on a screen.

What are the benefits of reading physical books?

Reading physical books has numerous benefits. For starters, it helps improve concentration and information retention. Physical books require more focus and concentration than digital books, as there are fewer distractions. This helps to improve memory retention and recall, especially for complex information.

Research suggests that reading online results in lower understanding and less critical reflection. That can even be the case when parents read to children from an ebook. But that’s largely because screens don’t help them enhance elements of the story that would make a book more engaging.

Learning is just better when it’s done on paper.

Physical books are also better for eye health. Digital screens emit blue light, which has been shown to disrupt sleep patterns and cause eye strain.

A paper book in your hands also helps promote relaxation (though we’ve certainly felt the relaxation from reading an ebook!). But it turns out physical books can help to reduce stress and anxiety. The act of holding a book and turning its pages has a calming effect, and the absence of screens and digital distractions can provide a sense of peace.

Paper books also encourage us to unplug. They provide a break from technology and encourage people to unplug and disconnect from their screens. This is especially important in today’s digital world, where people are constantly bombarded with information and distractions.

Love building a library

While ebooks can be very convenient for travel or people with small apartments who don’t have places to store books, it turns out that collecting physical books can be a source of pride and personal fulfillment. A personal library of physical books is a tangible representation of one’s interests and reading history, which can be enjoyed and shared with others. It makes people feel good about their reading habits.

Believe it or not, physical books are more environmentally friendly in some ways. They do not require any batteries, electricity, or other power sources. They are also made from natural materials, such as paper, making them a more sustainable option than digital books, which rely on electronic devices that contribute to electronic waste.

The benefits of reading physical books also help independent bookstores. And purchasing physical books from independent bookstores supports local communities and small businesses, helping to preserve the cultural heritage of local neighborhoods.

For the love of books

If you love books, you’re not alone. People still prefer and buy more physical books than ebooks. And considering how many devices we all own, that’s pretty impressive.

In an era where convenience rules, there’s still something so compelling about holding a physical book that ebooks have never been able to take the lion’s share of the book market. — WTF fun facts

WTF Fun Fact 13222 – Buffalo Tool Library

by

The Buffalo Tool Library is a magnificent idea that we wish could happen in every city. It would sure save us a lot of cash during our DIY home improvement adventures!

What is the Buffalo Tool Library?

The Buffalo Tool Library is a non-profit community organization that provides a lending library of tools to its members in Buffalo, New York. Members can borrow tools for home improvement, gardening, and repair projects, much like they would borrow books from a traditional library. The goal of the organization is to promote sustainability, community building, and self-sufficiency by making tools accessible to everyone.

The Buffalo Tool Library operates as a membership-based service. Members pay a fee to join and are then able to borrow tools from the library’s collection for a set period of time.

To borrow tools, members must check out the tools in person. They can do this either at the library’s physical location or through its online platform. The borrowed tools must then be returned in good condition within the agreed-upon loan period. Late fees may apply if the tools are returned past the due date.

The library also offers classes, workshops, and events to help members learn how to use the tools and develop new skills.

The library is run by volunteers. It relies on community support to continue its mission of promoting sustainability and self-sufficiency.

Building community

According to the University at Buffalo’s website:

“The Tool Library—which celebrated its eleventh anniversary this summer—lends over 4,000 tools, large and small, to over 1,000 individual and group members for both personal and collective projects. In addition to aiding personal do-it-yourself efforts, it organizes extensive community work: planting and maintaining trees, flowers, and neighborhood gardens; spearheading organized cleanups and streetscape and store-front maintenance; staging do-it-yourself and repair clinics; equipping and training in safety and lead abatement efforts.”

WTF Fun Fact 13220 – Chat Checkouts

by

Have you ever been in line at the store and rolled your eyes at the person chatting away with the clerk instead of getting their things together and leaving in a timely manner? That’s most of us. But for some people, that trip to the store may be one of the primary sources of socialization. That’s why the Dutch have invented “chat checkouts” (or Kletskassas). They’re primarily geared towards elderly people who want to take their time and chat people up at the store.

What are chat checkouts?

Chat checkouts are a type of Kletskassa, or social gathering, for older people. Community centers, cafes, or other public spaces often play host to these events. They provide seniors with an opportunity to socialize, make new friends, and engage in various activities such as playing games, singing, and chatting.

The goal of Kletskassa is to help combat feelings of loneliness and isolation among older people and provide them with a supportive community. So it makes sense to open up this opportunity in a place where everyone needs to go – the grocery store.

Jumbo’s nod to elderly shoppers

Dutch supermarket chain Jumbo announced the program in 2021. It said it plans to introduce 200 “chat registers” in its stores. These are for customers who aren’t in a hurry and want to have a chat during checkout, according to VICE (cited below).

“The initiative, announced by the popular supermarket chain Jumbo on Monday, is meant to combat loneliness—especially in the country’s elderly population. According to Statistics Netherlands, a government organization, 26 percent of Dutch people older than 15 feel at least moderately lonely. That proportion rises to 33 percent among those over 75.”

Customers were delighted by a pilot program Jumbo did of the chat checkout in 2019. The Dutch government will help sponsor it as part of their “One Against Loneliness” program.

“The Kletskassa is a checkout especially for people who are not in a hurry and feel like having a chat,” a Jumbo representative wrote in an email to Motherboard. “Many people, especially the elderly, sometimes feel lonely. It’s a small gesture, but a very valuable one, especially in a world that is digitizing and getting faster and faster.”  — WTF fun facts

WTF Fun Fact 13219 – DNA Sculptures

by

An artist named Heather Dewey-Hagborg has created DNA sculptures using genetic material from random items discarded by strangers.

How are DNA sculptures created?

Dewey-Hagborg first collects discarded DNA samples. These come from cigarette butts or hair. She then uses the DNA left on the items to generate 3D-printed portraits. In theory, these sculptures should reflect the physical attributes of the person from whom the DNA was taken.

The process starts with extracting the DNA from the sample. She then amplifies specific regions of the genome that are associated with physical characteristics, like hair color or facial structure. The amplified DNA is then sequenced to determine the individual’s genetic information. This information is used to create 3D models of the person’s face. Those models are then 3D printed for her art installations.

The artist bases the final sculptures of the sculpture on genetic information. But it also relies on assumptions about how genes influence physical appearance. So, in some sense, they are speculative. You likely wouldn’t be able to track down a person based on a sculpture.

In an interview in Interalia Magazine (cited below), Dewey-Hagborg explained her process. “I walked around picking up people genetic material and analysing it, making portraits, to show the coming risks of genetic surveillance. That as our DNA is increasingly legible (fast, easy, cheap to sequence) we are facing new cultural consequences.”

As for her goal:

“My goal, if I have one, is to inspire audiences to critically engage with science and technology in their lives. To be aware of structures around them, of things present or soon coming, and to think and talk about them with others; to discuss what should or shouldn’t be.  I hope that my work invites viewers into a visceral encounter with the near future.”

Genetics and art

By using DNA as a medium, Dewey-Hagborg tries to raise questions about the role of genetics in shaping our identities. Her work also has implications for thinking about advances in biotechnology for privacy and individuality.

Dewey-Hagborg has displayed her work at the World Economic Forum. She has also sold work to the Centre Pompidou, the Victoria and Albert Museum, the Wellcome Collection, the Exploratorium. She has a Ph.D. in Electronic Arts from Rensselaer Polytechnic Institute. — WTF fun facts

WTF Fun Fact 13218 – The Wall of Humanity

by

It likely started in Iran with the Wall of Kindness. One morning people woke up to a wall with graffiti telling them to leave what they didn’t need for those in need. More recently, Bangladesh’s Wall of Humanity has made the news due to its popularity in the winter months.

The rise of the Wall of Humanity

The “Wall of Kindness” is a charity initiative started in Iran in 2015. Since then, it has spread to other countries.

The idea behind the wall is to provide a place where people can leave clothing, food, and other essentials. Then, those in need can come and take what suits them best at the time.

People call it the Wall of Humanity in some countries. These walls are typically made up of hooks or shelves and signs. The goal is to allow people to easily hang up and take items without creating an eyesore.

The goal of the initiative is to encourage people to be more charitable. It also helps address poverty and homelessness in their communities.

Since 2015, these walls have become a symbol of hope and generosity. They’re also a reminder that small acts of kindness can make a big difference in people’s lives.

Building walls to join people together

According to the Wall of Humanity website:

“The concept of the ‘Wall of Humanity’ is to make a simple public wall transform into a social welfare center. It was initiated in 2015 by Pakistani Boy, Rohayl Varind with the sole purpose to win the war against poverty & hunger. Through this wall, people get free food, free ration, free medical checkup, free medicines, free clothes, free shoes, etc. It is an endeavor par excellence towards alleviating our species and taking humanity one step further to being called ‘Best of Creations’. Wall of Humanity has served more than 250,000 people all over the World specifically in India and Pakistan within the last 4 years.”

WTF Fun Fact 13217 – The Origin of the Taco

by

The exact origin of the taco is unknown, but we do have a best guess. What might surprise you is that tacos are a relatively new creation.

The first recorded reference to the word ‘taco’ was in the early 19th century in Mexico. The word “taco” is derived from the Nahuatl (Aztec) language, and has multiple meanings. It can be used to refer to a plug, a wedge, a tool, or to wrap something. The first taco was likely a soft corn tortilla filled with beans, chiles and tomatoes.

Studying the origin of the taco

Believe it or not, there is a taco expert. Granted, many of us consider ourselves expert taco eaters, but Jeffrey M. Pilcher, professor of history at the University of Minnesota, has actually studied the origin of the taco for 20 years.

According to Smithsonian Magazine (cited below), “he has investigated the history, politics, and evolution of Mexican food, including how Mexican silver miners likely invented the taco, how Mexican Americans in the Southwest reinvented it, and how businessman Glen Bell mass-marketed it to Anglo palates via the crunchy Taco Bell shell.”

In case you didn’t catch that, Taco Bell is the creation of a guy named Glen Bell.

Pilcher is the author of an entire book on tacos called Planet Taco: A Global History of Mexican Food (Oxford University Press). He also edited The Oxford Handbook of Food History and wrote The Sausage Rebellion: Public Health, Private Enterprise, and Meat in Mexico City, 1890-1917, and Que vivan los tamales! Food and the Making of Mexican Identity.

How did today’s taco come to be?

The term taco made its way to the United States in the late 1800s, when the popularity of Mexican cuisine began to rise. At first, the term was used to refer to the food item itself – the taco – but, in the early 1900s, it began to also be used as a descriptor for other foods, such as burritos, enchiladas, and tostadas.

Taco quickly grew to become an integral part of American culture. Americans embraced the taco as their own, adding their own unique ingredients and flavors, such as beef, lettuce, tomatoes, and cheese.

Pilcher notes:

“The first mention that I have seen [in the U.S.] is in 1905, in a newspaper. That’s a time when Mexican migrants are starting to come—working the mines and railroads and other such jobs. In the United States, Mexican food was seen as street food, lower-class food. It was associated with a group of women called the Chili Queens and with tamale pushcarts in Los Angeles. The Chili Queens of San Antonio were street vendors who earned a little extra money by selling food during festivals. When tourists started arriving in the 1880s with the railroad, these occasional sales started to become a nightly event.”

WTF Fun Fact 13216 – There’s Enough Iron in the Body to Make a Nail

by

The average human body contains enough iron to make a 3-inch nail.Well, a healthy body anyway. Some of us probably don’t get enough iron.

Is there really enough iron in the body to make a nail?

Humans require iron for many essential bodily functions. Iron is an essential mineral that helps transport oxygen throughout the body and is found in many foods such as red meat, poultry, fish, and beans. It is also found in food additives and dietary supplements, and is added to infant formula as well.

It’s important to note that iron deficiency is a common problem and can lead to anemia, fatigue, and impaired cognitive functioning. The World Health Organization recommends that people consume 10-20 milligrams of iron per day to maintain optimal health.

The average male body contains approximately 4.5 grams of iron, while the average female body contains approximately 3.5 grams. This means that the total amount of iron found in the human body is enough to make a 3-inch nail. Note: nails generally weigh between 2 to 3 grams.

Of course, no one is going to siphon the iron of your body and smelt it into a nail – hopefully.

What’s the significance of this concept?

Nails are often used as a metaphor for hard work. In that sense, it’s no surprise that the idea of making a 3-inch nail from the iron in the human body is a concept that fascinates people.

Iron can also be used to represent the ability to persevere and overcome difficult challenges. It conjures up images of fortitude and determination, courage, ad the will to succeed. Additionally, iron can also be used as a metaphor for protection. often a symbol of armor or a shield.

The metaphor of making a 3-inch nail from the iron stored in the body also speaks to our strength and resilience of the human body. It emphasizes the importance of how the iron in our bodies is used to help us do hard work.
