What a Black Hole Discovery Can Teach Us

First Ever Black Hole Pic

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.

How UK Schools Deal with Cell Phones

Cell Phones in UK Schools

Teachers have always had to fight for the attention of their students. Not long ago they would only be dealing with gossip, note passing, and the occasional trading card. The latest distraction of the mobile phone in the classroom can often be much more difficult to control.

Some teachers have even reported children watching Netflix in the middle of class. There a varying opinions on what should be done regarding the use of mobiles phones by students.

How UK Schools Approach Mobile Phones

Some countries – notably France – have strict laws against cell phone use in schools. There are no laws in the UK that prohibit children from using them. The decision on how to deal with phones is left to individual schools. It can get confusing and certainly far from consistent. Some schools do ban them outright, and then there are other schools that embrace phones as a teaching aid and encourage kids to use them as part of their schoolwork.

In Shiplake College in Henley-on-Thames for example, children that use their mobile phones between 8:15 and 5:45 are given a detention. The headmaster of the school, Gregg Davies, admits that phones can be a great tool, but he found children were being distracted and even losing their ability to communicate in person. The use of cell phones in school was therefore dropped since the policy was introduced.

Then there is Brighton College, where students are encouraged to play games like Monopoly and Trivial Pursuit during free periods, instead of using their cell phones. The move is an effort to encourage pupils to socialize with each other more without having to use mobile devices. There are also varying bans on phones where certain pupils are allowed them on certain days of the week; effectively weaning students off their phones over time.

How Phones can Help

The reality is that phones aren’t all bad and studies have shown that banning mobile phones can help in education. Students say that having their phones on hand can improve their engagement, motivation, productivity, and creativity. Some teachers also believe that mobile phones can help, and there have been successful integrations into the classroom.

Mobile phones can give students all the information that they could ever need. A phone by itself can educate students and there lots of phone apps that are even encouraged by schools, particularly those that build relaxation skills and help students find resources. The potential for phones as a learning tool is practically endless.

The Law on Confiscating Mobile Phones

One thing to consider is this; who is responsible if a phone is confiscated and then gets lost or damaged? Would it be the teacher who confiscated the phone, the student who brought it to the school, or the school itself?

Legally, the school has indeed taken possession of the phone. However, in the UK, Section 94 of the Education and Inspections Act 2006 says that neither the teacher or the school is responsible for loss or damage of items confiscated as a form of punishment. It also provides no statutory liability for items that are lost in other ways.

There are a few caveats though. The disciplinary penalty has to be lawful; it has to be reasonable and proportionate to the “crime”. Schools must also clearly communicate their policy on mobile phones to students. The school can get in trouble if the pupil who has their phone confiscated was not aware this could happen. Also, teachers are expected to take reasonable care to ensure that items they confiscate are safe, such as storing them securely in the staff room. At the end of the day, unfortunately for the students – the law is ultimately on the side of the teachers and schools.

Should Schools Ban Mobile Phones?

Matt Hancock – the Culture Secretary for the UK – says that more schools need to ban mobile phones. He admires headmasters who don’t allow students to use their phones and believes social media can facilitate bullying. He personally doesn’t allow his children to own their own phones and use social media, but doesn’t think it is the responsibility of the government to legislate against children using phones and technology. He believes it is up to parents and schools to do the right thing, rather than being told to do so by the government.

Schools are all handling cell phone use in their own way. Some are for them and some are against their use. The Culture secretary himself is against them, but doesn’t plan on attempting to introduce legislation to prohibit them.

How to Do Proper Research Using Google

Google Search is a powerful tool but most web surfers (kids and adults alike) do not know how to properly refine their search results to quickly find exactly what we’re looking for. For students doing research, it can lead kids and teens of any age down a convoluted rabbit hole.

Google was designed to do more than find trivial information.

Sure, if you want to find information about a celebrity you just “Google It”, but think about all the other information on the web that we don’t even know is there. Important information that can fuel research on many interesting topics.

While the early days of the internet didn’t even have highly developed search engines, it didn’t take long for developers to see the need for much more sophisticated search technology.

Although it wasn’t the first search engine in existence, Google spent a lot of time and money creating a better way to access quickly the expanding world wide web. As you’ll see in this infographic below, it’s much more than just entering a few keywords.

Even with our Google SafeSearch filtering, the more mouse clicks a person has to make in order to find what they are looking for, the higher the risk of landing on a website with inappropriate content… not to mention the time wasted and confusion causes when attempting to compile information.

Google was launched September 4, 1998. That’s over 20 years ago. Since that day there is a lot more information to be found online. Some of this information exists on reputable websites. It has properly researched and verified. On the other hand, much information is down right false.

It has never been more important to learn how to focus search results search engines like Google. These techniques were created to help you dig deep for information in a safe manner by filtering out unrelated websites.
