A train that circles around the earth! Coming soon?

Revolution in travel has always been a curious topic to all of us. Well this time it’s about an infinite model of a toy train! As to begin with, HO or H0 is the most popular scale model railway in the world. This continuous spiral of tracks was designed by a model train enthusiast James Risner who seems to have developed an endless bidirectional model of the trains. A hypnotic spiral of motion is created as the trains travel on forward at a surprisingly quick speed. If you observe closely, you will notice the differences between angular and linear velocity! All cars go the same speed ALONG the track, but inner cars go faster around the apparent circle which generates the so called hypnotic spiral. Another important observation you would make from the video is that that not a single car makes a full circuit. It gets quite close once or twice but then they would stop and send it in the opposite direction.

What this means in terms of revolutionizing travel is (if you could imagine) a flying train which circles around the earth, falls down because of the gravity and rises up due to its momentum. No more long tired long flights and no more expensive gas burners. Well before that would you consider building a replica of the same at your home? Your kids are gonna love this cool toy!

Team Work - Meaning and Tips for better Team Work

A single brain is not always capable of making key decisions on its own. To come up with an efficient solution, an individual requires the help and advice of others. A team is established when individuals get together on a common platform with the common goal of completing a task. To guarantee optimum compatibility, team members should ideally come from similar backgrounds and have a single aim. To provide their best, the team members must complement each other and function as a single unit in tight cooperation. "There is no I in Team Work," as the saying goes, and each member must put the needs of his team first. Personal interests must take a second seat. Any team's performance is directly proportionate to the relationship between its members and their combined efforts. What is the definition of teamwork? Teamwork is defined as the sum of each team member's efforts toward the fulfilment of the team's goal. In other words, any team's backbone is its ability t

Scientists discover a new theory / The fundamental property of light – 150 years after Maxwell

Light plays a vital role in our everyday lives and technologies based on light are all around us. So we might expect that our understanding of light is pretty settled. But scientists have just uncovered a new fundamental property of light that gives new insight into the 150-year-old classical theory of electromagnetism and which could lead to applications manipulating light at the nanoscale. It is unusual for a pure-theory physics paper to make it into the journal Science. So when one does, it’s worth a closer look. In the new study, researchers bring together one of physics' most venerable set of equations – those of James Clerk’s Maxwell’s famous theory of light – with one of the hot topics in modern solid-state physics: the quantum spin Hall effect and topological insulators . To understand what the fuss is about, let’s first consider the behaviour of electrons in the quantum spin Hall effect. Electrons possess an intrinsic spin as if they were tiny spinning-tops,
