Then, Now, Next

The UN has worked tirelessly to end wars and prevent conflicts. COVID-19 could make it harder.

True

In 1945, the world had just endured the bloodiest war in history. World leaders were determined to not repeat the mistakes of the past. They wanted to build a better future, one free from the "scourge of war" so they signed the UN Charter — creating a global organization of nations that could deter and repel aggressors, mediate conflicts and broker armistices, and ensure collective progress.

Over the following 75 years, the UN played an essential role in preventing, mitigating or resolving conflicts all over the world. It faced new challenges and new threats — including the spread of nuclear weapons and other weapons of mass destruction, a Cold War and brutal civil wars, transnational terrorism and genocides. Today, the UN faces new tensions: shifting and more hostile geopolitics, digital weaponization, a global pandemic, and more.

This slideshow shows how the UN has worked to build peace and security around the world:

The UN has worked to advocate for the concept of "human security," which elevates the safety of people above that of territory. In 2015, the Sustainable Development Goals linked security and development. They also enshrined the goal of building peaceful societies and reducing all forms of violence.

The Story of Bottled Waterwww.youtube.com

Here are six facts from the video above by The Story of Stuff Project that I'll definitely remember next time I'm tempted to buy bottled water.

1. Bottled water is more expensive than tap water (and not just a little).

via The Story of Stuff Project/YouTube


A Business Insider column noted that two-thirds of the bottled water sold in the United States is in individual 16.9-ounce bottles, which comes out to roughly $7.50 per gallon. That's about 2,000 times higher than the cost of a gallon of tap water.

And in an article in 20 Something Finance, G.E. Miller investigated the cost of bottled versus tap water for himself. He found that he could fill 4,787 20-ounce bottles with tap water for only $2.10! So if he paid $1 for a bottled water, he'd be paying 2,279 times the cost of tap.

2. Bottled water could potentially be of lower quality than tap water.

This Map Reveals The True Value Of $100 In Each State

Your purchasing power can swing by 30% from state to state.

Image by Tax Foundation.

Map represents the value of 100 dollars.

As the cost of living in large cities continues to rise, more and more people are realizing that the value of a dollar in the United States is a very relative concept. For decades, cost of living indices have sought to address and benchmark the inconsistencies in what money will buy, but they are often so specific as to prevent a holistic picture or the ability to "browse" the data based on geographic location.

The Tax Foundation addressed many of these shortcomings using the most recent (2015) Bureau of Economic Analysis data to provide a familiar map of the United States overlaid with the relative value of what $100 is "worth" in each state. Granted, going state-by-state still introduces a fair amount of "smoothing" into the process — $100 will go farther in Los Angeles than in Fresno, for instance — but it does provide insight into where the value lies.

Where is the third dog in this photo?

Optical illusions are wild. The way our brains perceive what our eyes see can be way off base, even when we're sure about what we're seeing.

Plenty of famous optical illusions have been created purposefully, from the Ames window that appears to be moving back and forth when it's actually rotating 360 degrees to the spiral image that makes Van Gogh's "Starry Night" look like it's moving.

But sometimes optical illusions happen by accident. Those ones are even more fun because we know they aren't a result of someone trying to trick our brains. Our brains do the tricking all by themselves.

Science

A 6-year-old asks ​Neil DeGrasse Tyson an adorable question. He gives her an awesome answer.

"The most beautiful thing we can experience is the mysterious. It is the source of all true art and science." — Albert Einstein

Neil DeGrasse Tyson at College of the Holy Cross in Worcester, MA.

I recently spent some time with Dr. Neil deGrasse Tyson. He's known not only for breaking down stereotypes about what kinds of people go into science, but he has actively stood up and spoken against those who would close its doors, especially to young women.

So when Neil was asked this question by a little girl during a public speech, he gave one of the best answers I've ever heard. It may drive some parents crazy, but it also might just help change the world.

Kara Coley, a bartender at Sipps in Gulfport, Mississippi, got an unusual phone call on the job last week.

"Good evening," Coley answered. "Thank you for calling Sipps!"

A woman on the other end of the line asked, "Is this a gay bar?"

Sipps welcomes everyone, Coley explained to her, but indeed attracts a mostly LGBTQ crowd.

An avocado tree farmer explains the science of Hass avocados

Have you ever seen anyone put an avocado pit in water to grow an avocado tree? I've seen lots of people try, but only a few succeed. My mom has a tiny avocado tree growing in her living room that she managed to grow from the pit of a Hass avocado she ate. It's small but thriving, and I've often wondered if it will ever grow actual avocados.

As it turns out, it could—but they won't be Hass avocados.

Wait, huh?
