Nikola Tesla and Tesla Tower…..

The tower went 187 feet up into the sky. The base was framed with wood, but the giant ball on top, 68 feet in diameter, was made of steel. In the ground below, there were said to be tunnels and an “iron root system” that went deep into earth. Nikola Tesla, the inventor and engineer who helped electrify America, believed the tower was the start of a system that could deliver electricity, without wires, to the whole world.

At the beginning of the 20th century, Tesla had become famous for his work on AC power. But he had other big ideas. At his laboratory in Colorado, he had conducted experiments with wireless transmission, trying to send electricity through the ground. His notes on this work are hard to draw conclusions from. But it seems that in at least one instance he had some success. At the very least, he came back east convinced that he could make this idea a reality, on a much larger scale.

After shopping his idea around to the some of the richest men in the world, Tesla secured backing—a solid $150,000—from J.P. Morgan. The investor was most interested in the idea of wireless communication: Guglielmo Marconi, an Italian inventor, had recently been demonstrating his system for wireless telegraphy, sending messages from ships back to land. But Tesla had bigger ideas.Wardenclyffe wireless station shown in 1904, and a portrait of Tesla, c. 1900. 

Construction began in 1901 in Long Island on what would become known as Wardenclyffe Tower. Tesla imagined that it would be the beginning of a network of towers, 30 at least, around the world. He believed that these towers would allow him to send electricity through the atmosphere, which anyone with the correct equipment could tap into. Electric power would be ubiquitous. He would make “the whole of this globe…quiver.”

This idea was never going to work: The scientific theories that underlay Tesla’s dream would later be pulled apart. Electricity can be transmitted through the air, but the amount of power needed to send any substantial amount makes this an extremely impractical system. But even to try it, Tesla needed more money, which Morgan was unwilling to provide. There were reports of sparks flying from the tower once or twice, but for the most part it remained a hulking metal orb of mysterious purpose.

After financing dried up, Tesla mortgaged the property and eventually, as his financial troubles grew deeper, he lost it altogether. In 1917, the new owner, trying to recoup some value, had the tower dynamited down and converted into scrap metal. After the first blast, the tower listed to the side and remained tilting towards the ground, a failed experiment, until the workers pulled it down.

How to spot an original thinker and become one……

‘Know that being quick to start but slow to finish can boost your creativity,’ says organisational psychologist Adam Grant.

Adam Grant is an organisational psychologist, and in his TED talk, he illustrates the surprising features of original thinkers, and teaches us how to be more like them. Speaking about ‘originals’, he says, “Originals are nonconformists, people who not only have new ideas but take action to champion them. They are people who stand out and speak up. Originals drive creativity and change in the world.”

Through multiple experiments and surveys as an organisational psychologist, he reveals he found three distinguishing habits of original thinkers. The first feature is that most original thinkers are procrastinators. He says, “Procrastinating is a vice when it comes to productivity, but it can be a virtue for creativity. What you see with a lot of great originals is that they are quick to start but they’re slow to finish.”

Secondly, original thinkers, too, have doubts and fears, but these help them to revise and improve upon their initial ideas. And lastly, Grant says, “If you look across fields, the greatest originals are the ones who fail the most, because they’re the ones who try the most.” Throughout history, original thinkers are known to have thought of several different ideas, out of which a small amount were absolutely groundbreaking.

“So if you put all this together, what you see is that originals are not that different from the rest of us. They feel fear and doubt. They procrastinate. They have bad ideas. And sometimes, it’s not in spite of those qualities but because of them that they succeed.”

“Know that being quick to start but slow to finish can boost your creativity, that you can motivate yourself by doubting your ideas and embracing the fear of failing to try, and that you need a lot of bad ideas in order to get a few good ones,” he concludes

U.N. reiterates call for global ceasefire in view of COVID-19 outbreak…..

The UN chief said support for his March 23 ceasefire appeal from governments, regional organizations, armed groups, civil society and individuals throughout the world has been encouraging – but he said in many instances challenges in implementing the ceasefire still need to be overcome.

The United Nations secretary-general is again urging factions in conflict to help tackle the COVID-19 pandemic.null

In a report to the UN Security Council released on Thursday, Antonio Guterres pointed to the more than 20,000 civilians killed or injured in 2019 attacks in 10 countries – and millions more forced from their homes by fighting.

He said the pandemic is the greatest test the world has faced since the United Nations was established 75 years ago and has already had a severe impact on efforts to protect civilians, especially in conflict-affected countries where weak health care systems can be overwhelmed.

Einstein’s scientific legacy……….

Einstein’s legacy in physics is significant. Here are some of the key scientific principles that he pioneered:

Theory of special relativity: Einstein showed that physical laws are identical for all observers, as long as they are not under acceleration. However, the speed of light in a vacuum is always the same, no matter at what speed the observer is travelling. This work led to his realisation that space and time are linked into what we now call space-time. So, an event seen by one observer may also be seen at a different time by another observer. 

Theory of general relativity: This was a reformulation of the law of gravity. In the 1600s, Newton formulated three laws of motion, among them outlining how gravity works between two bodies. The force between them depends on how massive each object is, and how far apart the objects are. Einstein determined that when thinking about space-time, a massive object causes a distortion in space-time (like putting a heavy ball on a trampoline). Gravity is exerted when other objects fall into the “well” created by the distortion in space-time, like a marble rolling towards the large ball. General relativity passed a recent major test in 2019 in an experiment involving a supermassive black hole at the center of the Milky Way.

Photoelectric effect: Einstein’s work in 1905 proposed that light should be thought of as a stream of particles (photons) instead of just a single wave, as was commonly thought at the time. His work helped decipher curious results scientists were previously unable to explain. 

Unified field theory: Einstein spent much of his later years trying to merge the fields of electromagnetism and gravity. He was unsuccessful, but may have been ahead of his time. Other physicists are still working on this problem.

What Was Galileo Famous For? …..

Galileo’s laws of motion, made from his measurements that all bodies accelerate at the same rate regardless of their mass or size, paved the way for the codification of classical mechanics by Isaac Newton. Galileo’s heliocentrism (with modifications by Kepler) soon became accepted scientific fact. His inventions, from compasses and balances to improved telescopes and microscopes, revolutionized astronomy and biology. Galilleo discovered craters and mountains on the moon, the phases of Venus, Jupiter’s moons and the stars of the Milky Way. His penchant for thoughtful and inventive experimentation pushed the scientific method toward its modern form.

In his conflict with the Church, Galileo was also largely vindicated. Enlightenment thinkers like Voltaire used tales of his trial (often in simplified and exaggerated form) to portray Galileo as a martyr for objectivity. Recent scholarship suggests Galileo’s actual trial and punishment were as much a matter of courtly intrigue and philosophical minutiae as of inherent tension between religion and science.

In 1744 Galileo’s “Dialogue” was removed from the Church’s list of banned books, and in the 20th century Popes Pius XII and John Paul II made official statements of regret for how the Church had treated Galileo

#NEAR_NATURE(1)

Captured by Ankit lamba

Touching feets of mother nature again and again gives us a chance to become one of it once again. It might sounds wired but it’s important to came back where we had started once, if you forgot your promise, if you forgot your words, if you forgot the reason than all the success is meaningless. It’s important to look behind for a while. I hope you understand………did you??
