As long as we walk this earth, one thing we should all discover is this. The more you know, the more you know you don’t know. That’s a quote from Aristotle, the Greek philosopher who lived over 2300 years ago. It basically means that no matter how much we learn in school as kids and later in life as adults, we’ll find there’s always more to learn about everything.

If we decide that we know everything there is to know and stop being opening to learning, we become ignorant and miss out so much that our wonderful world has to teach us.

As smart as Aristotle was, many things have been discovered in the hundreds of years since he lived. Many great philosophers and scientists have followed, and each one as built upon the knowledge of people who have gone before them.

The First Image of a Black Hole

Recently, the world’s greatest scientists of our day were finally able to create a real picture of a block hole. It was an amazing achievement and incredible discovery.  It confirmed many theories about the existence of black holes and how they work. It also proved that Albert Einstein was right about his Theory of General Relativity regarding the relationship between space and time.

The image also proved that recent scientific calculations about black holes were correct. This discovery, however, is more than a story about the advancement of technology that allowed humans to see an actual black hole for the first time. It’s also a story of how many scientists from all over the world worked together for many years to achieve this great feat.

For one, just to make the now famous black hole photograph took many observatories from all over the world working together to create one virtual telescope the size of our earth.

How Far Away is the Photographed Black Hole?

The black hole is located in the center of galaxy M87, which is about 55 million light years from earth. This means that light traveling from that point in space takes 55 million years to be seen on earth.

Think about it. The image we see of the block hole is like looking into the past. It’s light that started a journey to planet earth millions of years ago. Light from our sun takes an average of 8 minutes and 20 seconds.

The black hole has been named Powehi, which means ‘adorned fathomless dark creation’. Black holes have always fascinated scientists and students of astronomy because a black hole actually isn’t a hole. It’s a place in space containing a lot of matter closely packed together. It has accumulated so much gravity, that not even light can escape it. Therefore, it’s always black, even if it sucked our sun into it. And the black hole Powehi could easily do that because it’s about the same size as our entire solar system.

More Discoveries Yet to Come

While the first image of a real black hole confirms many theories that were calculated using mathematics, (see NASA Education’s Black Hole Math the Students), scientists are the first to point out that this great discovery is the beginning of many more discoveries yet to come.

Producing the black hole image took over 200 scientists working together from all over the world. They all would be the first to tell you that as much as we know about the Universe, there is so much more we don’t know.

The lessons we learn from the first image of a black hole are many. One important lesson is to always keep learning. You never know what amazing discovery you will find.

Wow! You learned how to do the front crawl, earned $63 dollars with your lemonade stand and your whole family spent a week at a resort all the way across the country. And every day of your summer break, as your thumb hovers over your phone, you need to ask yourself one question: Should I post this?

As you think about that great picture of your sister with cotton candy all over her face, remember one of the basic rules of social media posting: Do not post a picture of anybody without that person’s permission. That includes your sister. Remember, too, that while you might get a laugh at an embarrassing picture of your brother and his bar-b-que sauce accident, posting that picture could be something you regret for years to come.

Another thought to go over as your fingers find the post icon is this: How many pictures do I post? The answer: As few as possible.

When you send picture after picture after picture after picture, people start to get annoyed. It can also seem a little desperate to load your page with dozens of images from the same place. Better to choose two or three cool shots to post and save the rest to show your close friends when you get home.

When typing text on social media, less is also better. Shorter posts are more likely to be read and less likely to contain detailed, personal details that could be used to harm you or your family.

It’s also more fun to show pictures and describe details in person. Then you can make sure that you only share with friends that are close enough to meet face-to-face. You can see the looks on their faces when you tell them about that awesome midway ride.

Considering that you will have more free time to post on social media, this is a good time to double check your privacy settings. It’s also a good time to go through your “friends” and truly think about who you really—really—know. When you go through the list, you could find people that are complete strangers to you.

Summer is a time when you have more freedom to explore and enjoy the real world. So grab that opportunity. Put down your phone and truly experience your summer vacation. What you do this summer can change how you feel, think and what you do for the rest of your life.

Yes, it’s great to have pictures and share the experience with your “friends.” What’s more important is the way reality can shape who you are. Take it easy on the social media and discover that the most important “posts” are the ones that you carry in your head and your heart and share by how you live.

The internet offers a wealth of education and opportunity for kids, but many parents worry about the dangerous side of the online world—namely, the opportunity for their kids to stumble across inappropriate content or unsafe websites.

Or a child may unknowingly reveal private information to a stranger. This is where a few apps come in handy.

These four apps were designed with parents’ concerns in mind to help you keep your kids safe online.

1. Kaspersky Safe Kids

This app offers everything you need to monitor your kids’ smartphone activity, from blocking access to adult content and suspicious search results to monitoring app usage and setting device screen time limits. This app also offers tips from psychologists on how to teach kids about the dangers present online and how to take proper precautions.

Download the Kaspersky Safe Kids app for iOS devices or Android devices.

2. Kidgy

Wish you could know where your kid is at all times? Now you can with the Kidgy app. This location-sharing app makes it easy to keep track of your family and monitor their online activity. Check the real-time location of your kids, receive alerts when they leave from or arrive at home or school, set tasks for them to complete, and monitor text messaging.

Download the Kidgy app for iOS devices or Android devices.

3. KidzSearch Filtering

Sometimes something as simple or harmless as a misspelling can result in a search result gone afoul. Instead of letting your kid use Google.com for searches, KidzSearch automatically filters Google to remove inappropriate content and unsafe websites. With this app, your kids can use the internet as they typically would, and the parental filter helps keep them safe. This is the same filtering being used on Safe Search Kids, only through an app for mobile devices.

Download the KidzSearch app for iOS devices or Android devices.

KidzSearch also available on Kindle Fire / Amazon.

4. DinnerTime Plus

Getting kids to disconnect from their devices isn’t an easy task. This app makes it easier to require phone breaks. With a few clicks of a button, you can set time limits, requiring your kid to take scheduled breaks during dinner time, study time, and bedtime. You can also set schedules for how much time they can spend online and receive real-time usage monitoring.

Download the DinnerTime Plus app for iOS devices or Android devices.

With a few apps on your phone, you can always oversee your kids’ online activity. And remember, for these apps to work, you and your kids should have reliable internet access on your phones.

Setting up a hotspot will keep your child connected so you can use these apps and monitor their whereabouts and online searches any time you need.

Consider running a speed test as you’ll want to make sure you get at least 10 Mbps from your internet connection (more if you use a lot of devices in your home).

Once your apps are installed, you can feel more at ease with your kids’ online activity.

Do you really want someone to use your phone to record what you say without you knowing? Do you really want strangers looking at all your pictures and texts? Then you better learn about SMALL PRINT. How about strangers selling your pictures and texts to other people? Or following everything you do online?

Of course, secretly peeking into your life is wrong. Still, you probably clicked on a box that gave someone you don’t know permission to do just that.

Whenever you activate a phone or play a computer game or download an app, you see itsy bitsy print at the bottom of the pages. Those tiny words are filled with things that you need to check off before you can use your new computer or play that new game.  Those words can be so small that you probably can’t even read them.

If you could read them, they’d sound like gibberish. Many adults with years of education have trouble understanding what those weird words mean. Your parents should look at any small print that you check off, but they might have problems figuring out what they say. What people do know is that when you check the “AGREED” box, you give strangers permission to do scary things.

Do you:

– use a web browser?

– play games online?

– download apps to your phone or computer?

– upload pictures for your friends to see?

-store pictures or text in a cloud?

If you do, then here is a list of just some of the things that you have probably agreed to let strangers do:

• turn your video and audio recorders on
• take and use your pictures and videos
• turn your gaming machine off forever
• track everything you do online and share or sell your activity
• prevent you or your parents from legally stopping people from sharing details from your lives.

Small print is tricky. Teams of well-trained lawyers spend thousands of hours working on every little word. All that time and all those brains are there to protect the big companies that you use online. It’s up to you and your parents to protect YOU.

Make a point of looking for small print. Grab a bunch of your friends and see if all of you can figure out exactly what you agree to when you click that little box. You will be surprised.
