Sometimes the most advanced forms of technology are also the simplest. The LightSail 2, a satellite conceived by Bill Nye's non-profit Planetary Society, has proven that a satellite can orbit the Earth fueled completely by the sun. The concept, dreamed up 400 years ago by Johannes Kepler, has finally become a reality.

The LightSail 2 doesn't run on solar panels but instead solar sailing – an entirely different concept. It's kind of like a sailboat, but instead of using wind to make it move, it's powered by photon particles from the sun that bounce off of a sail made from a large reflective surface. The photon particles give it a "tiny push no stronger than the weight of a paperclip," Nye told CNN.

Photons (aka light particles) have no mass, however they do provide momentum and can be used to push the satellite through space. "It's counter-intuitive, it's surprising, and to me it's very romantic to be sailing on sunbeams," Nye said.

The LightSail 2 was completely crowdfunded. Nye and Neil deGrasse Tyson launched a Kickstarter campaign in 2015, which raised over $1.2 million for the project. All in all, the project cost $7 million, which took 10 years to collect. 50,000 supporters from 109 countries contributed, getting the most valuable return on investment of them all.

"The type of return on investment these people get is just knowledge," Planetary Society COO Jennifer Vaughn told CNN. "It's capability. That's the kind of returns these people are looking for."

As of now, Nye said there are no plans to do a third light sail. However, the success of the LightSail 2 could mean the technology gets incorporated into larger projects, such as those that extend beyond the orbit of the Earth. Nye wants to see the LightSail 2 complete exploratory missions such as those that monitor the sun and provide warning of solar flare-ups.

"Solar sailing is in its infancy, but it may become a game-changer," Nye said in an interview with Digital Trends. "We'll soon be able to send our solar sail spacecraft to all sorts of destinations in our solar system, and perhaps to another star system one day."

It is said that once you've seen something, you can't unsee it. This is exactly what is happening in America right now. We have collectively watched the pot of racial tension boil over after years of looking the other way, insisting that hot water doesn't exist, pretending not to notice the smoke billowing out from every direction.

Ignoring a problem doesn't make it go away—it prolongs resolution. There's a whole lot of harm to be remedied and damage to be repaired as a result of racial injustice, and it's up to all of us to figure out how to do that. Parents, in particular, are recognizing the importance of raising anti-racist children; if we are unable to completely eradicate racism, maybe the next generation will.

How can parents ensure that the next generation will actively refuse to perpetuate systems and behaviors embedded in racism? The most obvious answer is to model it. Take for example, professional tennis player Serena Williams and her husband, Reddit co-founder Alexis Ohanian.

This week, viral photos from the first day of school in various Georgia counties showed students crowded together with few masks in sight. Schools in the same area had to shut down entire classrooms due to positive tests after the first day back, quarantining students and teachers for two weeks.

In these counties, students are "encouraged" to wear a mask at school, but they are not required. Mask-wearing is referred to as a "personal choice."

This week, a private Christian college in a town near where I live announced that is planning to resume in-person classes this fall. The school has decided that students will not be required to wear masks, despite the fact that the town itself has a mask mandate for all public spaces. "No riots. No masks. In person. This fall," the college wrote in a Facebook post advertising the school last month.

The supposed justification for not requiring students to wear masks is that it's a "personal choice," and that students have the freedom to choose whether to wear one or not.

That's a neat story. Except it is totally hypocritical coming from schools and school districts that have no problem placing limits on personal choice and freedom by mandating stringent dress codes for students.

As you sit down to eat your breakfast in the morning or grab an afternoon snack, take a minute to consider your food, how it was made, and how it got to your plate.

The fruit on your plate were grown and picked on farms, then processed, packaged and sent to the grocery store where you bought them.

Sounds simple, right?

The truth is, that process is anything but simple and at every step in the journey to your plate, harm can be caused to the people who grow it, the communities that need it, and the planet we all call home.

For example, thousands of kids live in food deserts and areas where access to affordable and nutritious food is limited. Around the world, one in three children suffer from some form of malnutrition, and yet, up to 40% of food in the United States is never eaten.

I saw this poster today and I was going to just let it go, but then I kept feeling tugged to say something.

While this poster is great to bring attention to the issue of child trafficking, it is a "shocking" picture of a young girl tied up. It has that dark gritty feeling. I picture her in a basement tied to a dripping pipe.

While that sounds awful, it's important to know that trafficking children in the US is not all of that. I can't say it never is—I don't know. What I do know is most young trafficked children aren't sitting in a basement tied up. They have families, and someone—usually in their family—is trafficking them.

Over the past few years, there has been a growing movement to fight back against some of the everyday racism that exists in America.

The Washington Redskins of the NFL have temporarily changed their name to the Washington Football Team until a more suitable, and less racist, name is determined.

The Dixie Chicks, a country band from Texas has decided to change their name to The Chicks to avoid any connotation with slavery, as has Lady Antebellum who now just go by Lady A.

(Although they stole the name form a Black woman who has been using it for over 20 years.)
