The Continental Drift Continental drift is the suggestion that over long periods of geological time, the continents of the Earth have moved apart from each other and had once formed almost one single land mass known as Pangaea. Whilst the theory that the continents had moved over time had been speculated upon before, the theory wasn’t properly developed until 1912....

History of atom Our journey with the atom model dates back to 442 BC when Greek Philosopher Democritus proposed his theory of matter. While his theory was obviously not based on any observable science, it was entirely dependent on rationalism and was largely inspired by Greek philosophers, Leucippus and Anaxagoras. Democritus enters this discussion facing phenomenal resistance. His proposition so...

This period of discovery lasted from about 1418 to 1620. During this time, European explorers made many daring voyages that changed world history. A major reason for these voyages was the desire to find sea routes to East Asia, which Europeans called the Indies. When Christopher Columbus sailed west across the Atlantic Ocean, he was looking for such a route....

Safe Sound Level Practical Sound are waves produced by vibrations (OpenLearn, 2017). They can travel through solids, liquids and gases. However, the particles move differently in each of these forms. Sound waves travel fastest in solids, followed by liquids, then lastly gases (Oceanservice n.d). The molecules in solids are the most compacted, enabling sound to travel much faster in solids...

In antiquity, philosophers posited a variety of ways in which the physical world is constructed. One such philosophy is that of Atomism, which proposed that the universe was made of indivisible, granular elements: atoms. An early example of a philosopher proposing atomism is Aruni, a Vedic scholar from 8th century BCE India, who theorized that particles too small to be...

Niels Bohr, who was interested in explaining the spectrum of discrete lines that is observed when light is emitted by different elements. Many models of the atom have been proposed based on experimental data, including J.J. Thomson's discovery of the electron and Ernest Rutherford's discovery of the nucleus. Rutherford explained that in an atom, the nucleus is positively charged and...

Abstract Have you ever wonder why ice cubes floats when mixed with water? or when oil stays at the top of the water instead of mixing together? This goes back to 250 B.C when a Greek mathematician named Archimedes discovered density. Density explains the correlation of mass and volume and also when the object is supposed to rise, sink, or...
