The structure of a snowflake is quite complex. It is formed from a frozen drop of cloud, which forms the nucleus. The nucleus quickly attracts water molecules around it that freeze instantly. In the process, the attracted water molecules branch out giving the snowflake a unique hexagonal shape. Since the branching out process is different…
The Akashi Kaikyō bridge links the island of Honshu to Awaji island. It has a central span length of 1991 metres, the longest span of any bridge on earth. There are other two spans or sections, each measuring 960 metres or 3,150 feet. The bridge has a total length of 3,911 metres or 12,831 feet….
The Möbius strip is formed by taking a rectangular strip of paper and connecting its ends after giving it a half twist. It is a surface with only one side and one edge. In 1858, the properties of the strip were discovered independently and almost simultaneously by two German mathematicians August Ferdinand Möbius and Johann…
The theory of evolution states that species evolved as a result of natural selection, and could adapt to harsh conditions. This theory was put forth simultaneously by the two English naturalists Charles Darwin and Alfred Russel Wallace.
Professor Jagadish Chandra Bose demonstrated that the electric rays had the ability to travel long distances without the help of any wire. He did so by initiating the electric rays using a radiator in the lecture room, which passed through three solid walls of the lecture room, an intervening room, to a third room. The receiver…
Water evaporates from oceans, seas, rivers, etc., and rises up in the atmosphere. At the height of several thousand kilometres, these vapours condense to form clouds and eventually droplets. By this time, the droplet may have travelled many miles from its place of origin. Once the droplets reach a certain size, typically 6 mm in diameter,…
