Do You Feel Alone? – By Kurzgesagt

By Anupum Pant

If you feel worthless or alone, or both, you probably are looking at things very superficially. It’s time to realize who you are and where you stand in this vast universe.

Today, I’m just going to leave you with a brilliantly animated, science + philosophical video by Kurzgesagt.

(Just that because I’m too tired to write and happened to stumble upon this amazing video which I felt like sharing)

Also, don’t forget to check out their other videos. All of them are brilliant. Yes, I’ve watched them all. [Channel link]

The Greenest Invader in the History

By Anupum Pant

Background

The impact of human activities on climate change is by no means new. It is not an 1800s or 1900s thing. It did not start happening when we started burning huge amounts of coal or oil. In fact, human impact on the climate has been here for a long long time now. It started happening about thousands of years ago when our ancestors started clearing forests to make land for cultivation. The impact was less back then, but it had started.

So, basically an overly simplified equation has been like this – more humans, more cleared forests (for cultivation), more carbon emissions.

All these years humans have also been hit by some very unfortunate historical events which have resulted in the death of a great number of people.  Of course these events like the fall of Ming dynasty,  Black death and Conquest of America were sad events. They resulted in a massive wipe-out of human population which we would not wish to see ever again.

However, the huge number of deaths that happened due to these unfortunate events did have a common salubrious effect on our planet. Huge tracts of cultivated lands turned back into forests. As a result, great amounts of carbon dioxide got absorbed and there was effectively a global cooling happening.

The Mongol Invasion

Among all these historical events, one stands out – The Mongol invasion which lasted for about 150 years and covered more than 20% of Earth’s surface.

After founding the Mongol empire, Genghis Khan has been believed to have started these Mongol invasions. Time and again he was involved in the decimation of huge settlements. It is estimated that these invasions led by Genghis Khan resulted in the death of a whopping 40 Million people!

Death of so many people meant that the cultivated lands of settlements started turning back into forests and these forests ended up absorbing huge amounts of carbon dioxide from the air. Result – Global cooling (kinda).

It is estimated that the Genghis Khan invasions helped remove about 700 Million tons of carbon from the atmosphere. That about the same as a whole year of carbon that is being put back into the air due to burning of petrol today, in this industrialised world!

Genghis Khan has been branded the greenest invader in history.

Michio Kaku’s High-School Science Fair Project was Astounding

By Anupum Pant

 michiokakuDr. Michio Kaku without a doubt is one of the finest Physicist of the present times. Besides that he is also a very popular person. If you watch TV, you must have definitely seen this man some where. He has made several appearances on TV channels like  BBC, the Discovery Channel, the History Channel, and the Science Channel. Also, he has written books and hosts a radio show.
He has made science popular. But if you live in a cave, this person in the picture is the man I’m talking about.

What made him the man he is today, was his great love for science since childhood. By the time he was in high-school, he had started doing incredible things. His high-school science fair project story, pretty much sums up the remarkable things he had started doing back then.

The science fair project

During his high school, when he was working on anti-matter photography, he had an idea to create his own anti-matter beam. He then went to his mom and asked her this:

Mom, can I have permission to build a 2.3 million volt atom smasher betatronic accelerator in my garage?

The shocked and proud mom obviously agreed to the proposal. This is what he had to procure to convert his idea into a reality:

  • 400 pounds of transformer steel
  • 22 miles! of copper wire

With the help of his parents, he wound the 22 mile long copper wire around a football field that was able to generate a magnetic field 20,000 times greater than the Earth’s magnetic field. It could produce collisions powerful enough to create antimatter. After a few troubles with the power, there, he had his own  2.3 eV atom smasher (cyclic particle accelerator).

This was an atom smasher built in his backyard garage – a mini version of the $ 10 Billion Large Hadron Collider.

Changed his life

This science fair put him in the right track. A nuclear scientist, Edward Teller, noticed it in the National Science Fair and spread the word to the scientific community. And soon, he got a full ride to the Harvard University.
