For some guns might be a sensational invention while for others it might be a dreadful invention.
Weapons have been the primary tools since ancient age. But, it is an undeniable fact that the Guns have revolutionized the world.
The earliest usage of a firearm might have been in China during the 13th century CE. In earlier days, guns were fired by holding a burning wick to a "touch hole" in the barrel igniting the powder inside.
The first machine gun is the matchlock, which dates to 1400s. By the 12th century, the technology started spreading to Asia, followed by Europe. The problem of loading and reliability was solved by the invention of a hand-driven machine gun called Gatling gun. It was invented by Richard J. Gatling during the American Civil War. As the tech continued to evolve, each following model became more deadly.

Team Work - Meaning and Tips for better Team Work

By
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.

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

By
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,
