Warp speed—"Make it so!"

"Prepare for warp speed." If you're a Trekkie or Star Wars fan, and maybe even if you're not, you've heard about warp drives and probably dreamed of being able to travel faster than the speed of light. It seemed like the stuff of fantasy—until now. Physicist Erik Lentz has come up with a theoretical model of a warp drive that would shorten a trip to the star Proxima Centauri, the closest star beyond our solar system, from 50,000–70,000 years using rocket fuel, or 100 years using nuclear fuel, to just 4 years and 3 months.

The theoretical warp drive as it stands now would need the energy of 100 times the mass of Jupiter to work. So it's still far from becoming a reality. But Lentz says that the next phase of research and development could bring a working prototype within the next decade, and actual warp speed travel within the decades following. “I would like to see this technology in use in my lifetime,” he says. So would I! I probably won't, given my age, but my grandchildren could. Imagine a world where warp speed travel is commonplace. What might we find out there? Or who?

Opera helps COVID-19 patients

The English National Opera (ENO) has teamed up with a London hospital to teach breathing techniques to people recovering from COVID-19. One of the common lingering effects of the virus is difficulty breathing. Proper breathing is essential for opera singers, so they're in a unique position to help patients recover. 

When in-house opera concerts were cancelled due to the pandemic, the ENO wanted to find other ways to use their skills to help others. They realized they are experts in breathing, so they created a 6-week program, called ENO Breathe, that uses therapeutic techniques reworked by singers. The techniques help restore lung capacity, as well as lessen anxiety through deep breathing exercises.

ENO Breathe recruited 12 people for a pilot program, and it was so successful that the program is being expanded to include other clinics in England. Patients who've taken the lessons say that it has definitely helped. Wayne Cameron, a participant in the program, said, "The program really does help—physically, mentally, in terms of anxiety.”

ENO Breathe has helped not only COVID-19 patients, but also the opera singers themselves. As Jenna Mollica, director of the ENO's outreach programs, puts it, “Everyone’s found it really motivating. It’s fantastic to realize that this skill set we have is useful.”

The main religions of the world

People around the world follow different religions. We use specific words to describe them.

  • Christians worship Jesus Christ. They believe he is the son of God. There are three main types of Christians: Catholics, Protestants and Orthodox.
  • Muslims are part of a religion called Islam. They believe that Jesus is only a prophet. Their main prophet is Muhammed. Most Muslims are either Sunni or Shia.
  • Jews follow Judaism. Their main prophets are named Moses and Abraham. Christianity and Islam were inspired by Judaism.
  • Buddhists follow the teachings of Buddha, who said there is no God. The three main types of Buddhism are Theravada, Mahayana, and Vajrayana.
  • Hindus belong to Hinduism, a religion with many gods. When a religion has many gods, we call it polytheistic. When it only has one God, it is monotheistic.

The ego's effect on leadership

According to the Harvard Business Review, the higher leaders rise in the ranks, the more they are at risk of getting an inflated ego. The bigger their ego grows, the more they are at risk of ending up in an insulated bubble, losing touch with their colleagues, the culture and ultimately their clients.

An unchecked ego can warp our perspective, twist our values and corrupt our behavior. When we believe we’re the sole architects of our success, we tend to be ruder, more selfish and more likely to interrupt others. An inflated ego also narrows our vision. The ego always looks for information that confirms what it wants to believe. Basically, a big ego makes us have a strong confirmation bias.

Breaking free of an overly protective or inflated ego requires selflessness, reflection and courage. Consider the perks and privileges you are being offered in your role. Some of them are simply perks to promote your status and power and ultimately ego. Support, develop and work with people who won’t feed your ego. Humility and gratitude are cornerstones of selflessness. Make a habit of taking a moment at the end of each day to reflect on all the people that were part of making you successful on that day.

Crossing the street in Vietnam

Crossing the street is very easy in most countries. You simply wait for the crosswalk light to turn green. The cars stop and let you walk safely to the other side.

However, in Hanoi, Vietnam, crossing the road is an adventure. There are few traffic lights, and the cars and motorbikes will never stop for you. You need to just walk into the street and the vehicles will go around you. It can be very scary, but that is the only way to cross the street in Vietnam. You have to trust the drivers not to hit you.

You get used to it very quickly and then laugh when you see tourists panic while crossing the street.

Can language change culture?

Languages generally develop organically, following changes in culture. But sometimes we have to purposefully change our language to create the culture we need.

Take, for example, sexism. In English, seeing the masculine form of a word—e.g., adding "-man" to a job title, and using he/him/his pronouns—as neutral had been accepted as the norm since the 19th century and still often is. In the 1970s, however, women began to demand equal representation in all things, and that meant in the language, too. 

Studies have shown that people are influenced by the words they see. In one study, people were asked to read a story with the following sentences in it:

  • “The foreman reassured himself he had made the right decision.”

  • "The foreman reassured herself she had made the right decision.”

When people read the first sentence, they continued on without thinking about it. When they read the second one, they stopped and went back to check that they'd read the sentence right. So masculine forms are clearly seen as masculine, not neutral. It's time to change the language to let everyone in.

Will US hedge funds go bankrupt?

An interesting situation has emerged in the American stock market. It has caused the stock of several companies to be extremely volatile.

Hedge funds in the US have opened so many short positions—basically, they have bet that stock prices will fall. Now it is believed that they have short sold more than the number of shares available on the market.

However, savvy retail traders noticed this. They started to buy up these shares in large volumes in the hope to push up the price.

Trading has been so aggressive that the share prices have wildly fluctuated and multiple brokers have been refusing to even allow purchases. The situation has gotten lots of attention, with multiple members of congress showing interest in the behaviors of brokers and hedge funds. Some have called for congressional inquiries.

It isn't clear what the aftermath will be. Only time will tell.

The Swiss Cheese model of defense

Human beings are flawed. So no system of defense that depends on human action is going to be able to protect us 100% of the time. But we can prevent most problems. In 1990, Professor James Reason came up with the "Swiss Cheese model" to create defenses that are hard to break through.

Think about Swiss cheese—it has lots of holes in it, right? Well, the Swiss Cheese defense model takes the "holes", or human flaws, into account by using several layers of defense. Each layer has holes, but not every layer has the same holes. So, put enough different layers together and there won't be a complete series of holes that line up to allow something through. Each human failure will be blocked by other successes.

Scientists and public health specialists are using this model to protect us from the novel coronavirus with layers of protective practices like wearing masks, washing our hands, staying home, etc. As we know, not everyone follows all those measures. But if enough people do, the holes will be smaller and more layers will be in place to block them. We'll be able to slow the rate of infections—and deaths—dramatically.

The success of Bookshop

According to The Guardian, a newspaper based in the United Kingdom, Bookshop is a socially conscious alternative to Amazon that allows readers to buy books online while supporting their local independent bookseller.

Bookshop was founded by writer and co-founder of Literary Hub, Andy Hunter. It allows independent bookshops to create their own virtual shopfront on the site, with the stores receiving the full profit from each sale. Customer service and shipping are handled by Bookshop and its distribution partners.

Launched in 2020 with 88 bookshops, by the end of that year they had grown to over 1,000 and raised over ten million dollars for the affiliated bookstores. Hunter believes the reason for Bookshop’s quick success is readers’ fondness for their local booksellers. “Bookstores have been in trouble for a while because of Amazon’s growth, but the pandemic really accelerated it. Amazon has gotten much more powerful, while there are 100-year-old stores that are hanging on for survival,” he said. “I think we were so successful because enough people were conscious of that, and wanted to rally around their beloved bookstores.”

Personal: Looking back on 2020

This year has certainly been a rollercoaster. There were highs and lows, not to mention a lot of uncertainty—sometimes all you could do is throw your hands up and hope for the best. 

Looking back on 2020, there are a few things that changed. 

First, since restaurants were closed during lockdown, my approach to home cooking changed. Before COVID, I took an ad-hoc approach to meals. But with limited trips to the grocery store and fewer options for take-out dinner, I started planning and following recipes more carefully. The result was better meals with fewer headaches. That was one takeaway: prepare well and rely on experts to write the recipe. 

Secondly, I've started taking hygiene even more seriously. I wash my hands for longer (20 seconds at least) and I avoid touching things out in public—that includes buttons at pedestrian signals and packages at the supermarket. That's another takeaway: do simple things to avoid getting sick. 

Finally, I've gotten a little uncomfortable with crowds. Movie theaters, concerts and even big parties seem a little more anxiety-inducing than they did a year ago. I hope this fades though. I love quality films and live shows, and I hope to see as many as possible in 2021.

Giant beasts made of rice straw

Rice straw, or wara, is the waste left over from rice production. It used to be used to make tatami mats, bags, and other daily goods, including shoes. But these days most things are made from plastic and other synthetic materials, so farmers are left with mountains of useless wara. In 2007, farmers along with the tourism board of Niigata City in the Niigata prefecture, asked Professor Shingo Miyajima of the Department of Science and Design at the Musashino University to come up with a creative solution to the problem. He suggested using it to make art.

So in 2008, students from the university traveled to Niigata to create sculptures with wara. Niigata's tourism board was hoping to draw more visitors to the area, and organized a festival to showcase the sculptures. It was a huge success! Mushashino art students and farmers have continued to work together every year since to recycle waste products into art.

In 2017, to celebrate the festival's 10th anniversary, the art students were asked to create sculptures twice as big as usual. The results were fantastic! Normally about 4 meters high, the 2017 sculptures reached as high as 9 meters or more! Giant wooden frames were constructed in the basic shape of the sculpture, then thousands of wara bunches were attached to flesh it out. An arduous process that results in stunning works of art. 

(In 2020, the festival had to be cancelled due to the pandemic.)

Virtual listening

The COVID-19 pandemic forced most professionals around the world to begin working from home in early 2020. Suddenly teams were separated and had to communicate over video call services. It’s hard to feel connected that way. And it’s hard to build relationships and maintain the trust that today’s business depends on. 

Since this situation may continue for quite some time, we need to figure out how to make it not just work but work well. Katy Lindsay of Aptimore suggests a couple of things to do on a virtual call to create a sense of “active listening”. Vocal cues won’t work when the software tracks whoever’s speaking—the whole meeting is disrupted by people listening actively. So Katy recommends gently nodding and smiling to communicate that you’re paying attention. If you don’t consciously make a point of looking engaged, you’ll probably just have a blank face, which is really dispiriting for a speaker. Especially if everyone on screen looks like that!

And although it’s tempting when you’re not in the same room with the rest of the team, don’t try to multitask. It’s all too obvious when you’re looking down at your phone instead of paying attention to the speaker. And you just might miss some important information while checking those emails and text messages.

Visuals: language speed & density

According to The Economist, languages face a trade-off between complexity and speed. Those packed with information are spoken more slowly, while simpler ones are spoken faster. As a result, most languages are equally efficient at conveying information.

For instance, a Japanese translation of this text would be longer and a Thai one would be shorter, but readers would finish reading it at about the same time.

Black holes support relativity

Albert Einstein spent nearly a decade developing his theory of general relativity, which he published in 1916. The theory asserts that gravity is matter warping space-time and so gravitational bends in space can alter the passage of time. While an appealing theory, it is yet unproven.

According to CNN, the first image of a black hole, captured in 2019, has revealed more support for Einstein's theory. The new finding has suggested his theory is now 500 times harder to disprove.

The black hole in this study is 6.5 billion times more massive than our sun. The research team measured the distortion in the black hole’s gravitational pull and found that the size of this black hole's shadow aligns with the theory of relativity, or matter warping space-time to create gravity.

While the theory of relativity has passed all of the tests thrown at it over the past century, further study is needed to confirm whether it continues to match up with astrophysical objects.

The mission of the century

CNN reports that according to the International Air Transport Association (IATA), providing a single dose of a future coronavirus vaccine to all 7.8 billion people in the world will require the use of 8,000 Boeing 747 cargo aircraft, and that planning needs to begin now.

IATA's director general and CEO, Alexandre de Juniac, said in a public statement that "safely delivering Covid-19 vaccines will be the mission of the century for the global air cargo industry."

There are multiple vaccines being tested in human trials simultaneously around the world. Once a vaccine is approved for use, licensing and large-scale manufacturing will take place. However, without proper planning, these vaccines won't be able to fly the skies.

Among the major concerns cited by IATA is the availability of temperature-controlled facilities and equipment, along with trained staff. Also, the current border restrictions will need to be eased, permits for operators carrying the vaccine will need to be fast tracked, and the flight crew members exempted from quarantine requirements to ensure cargo supply chains are maintained. A final concern is security, with IATA noting that vaccines will be highly valuable commodities. Therefore, shipments will need to be secured and protected from tampering and theft.

The decline of the yakuza

The Guardian reports that more than a decade of police crackdowns on major gangs and economic uncertainty are making it harder for the yakuza to tempt young men with promises of easy money.

For the first time since records began in 2006, 51% of regular yakuza members are aged 50 or over, according to a new report by the national police agency. Less than 15% are under 40, and those over 70 account for just over 10% of total membership.

Stricter laws, including those targeting businesses with links to gangs that had once operated with near-impunity, have made a life of crime increasingly unappealing. Yakuza members are forbidden from opening bank accounts, obtaining a credit card, taking out insurance policies or even signing a contract for a mobile phone.

“My generation dreamed about becoming high-ranking gang members who were popular with women, had money and drove fancy cars,” a former gangster who retired in his 70s told the Asahi Shimbun. “But the times have changed. Young people today don’t like the idea of being tied down to a gang.”

Venture capitalism and online games

Unable to hold face-to-face meetings with potential investors, venture capitalists are seeking new ways to meet start-ups, including a service which arranges virtual meetings inside the video game, Fortnite.

Matchbox.vc matches technology investors with start-up executives through video game sessions in the hopes that companies will find their dream investment.

“Games are an incredible way for people in tech to connect,” said the site's co-founder, Alex Walsh. “It's a lot less stressful since both parties are doing something they enjoy, making it perfect for a first meeting. It's just like any other activity that's been tangential to business for years, like golf, getting coffee, or going for a walk.”

As of early 2020, Matchbox.vc had already been used by investors from prominent funds including Sequoia, Accel, Peter Thiel’s Founders Fund and Samsung’s venture capital wing. With more and more companies asking employees to work from home, services like Matchbox.vc are likely to become more popular.

Flip-flops made from algae

Algae is used in lots of ways, from food to health supplements to fuel. Now we can add flip-flops to the list. Flip-flops, commonly made from rubber, foam or plastic, are hugely popular all over the world. When people lose theirs on the beach, which happens frequently, the flip-flops are swept into the ocean to join the rest of the plastic pollutants collecting there. 

To solve this problem, new biodegradable "plastics" are being developed using something else found on the beach: algae. A chemistry professor at University of California, San Diego, Mike Burkart, is spearheading a project to make flip-flops out of algae so that, instead of creating pollution, they decompose naturally. Major shoe manufacturers are talking with Burkart about using his material, as are producers of food storage containers and other plastic items. 

Sometimes it might seem like our environmental problems are incurable, and then someone like Burkart comes along and offers a seemingly simple solution. Let's hope it works.
