There, in front of a room full of physics students, Hans Christian Oersted (1777–1851) discovered that electricity can produce magnetic fields. Oersted was the son of a Danish pharmacist, and he had planned to follow his father’s profession, but he became captivated by electrical studies in 1800. He gained great popularity as a science lecturer and was given a professorship at the University of Copenhagen...Read More

But as unimaginable it may sound to us now, the story of electricity for practical use has been around for only few centuries. Most modern uses of electricity rely on electrons that move. Newton’s first law of motion demands that electrons can’t move unless a force is applied. A method for applying such a force was discovered in 1794, when the Italian physicist Alessandro Volta (1745–1827) invented the battery. Alessandro Giuseppe Antonio Anastasio Volta was born...Read More
The first law of thermodynamics states energy can’t be newly created nor destroyed; so where did the universe come from? Did the origin of universe require a super natural explanation? New understanding of cosmology however shows, despite our intuitions, the net energy of universe is 0 and the whole universe could indeed come out of the “quantum foam” of nothingness, according to Stephen Hawkins and others. A brief overview of the implications of this dramatic new insight.Read More
The study of energy is called thermodynamics. Unlike Newton’s laws of motion, the laws of thermodynamics did not spring fully formed from one mind. Rather, these ideas emerged gradually from the work of many researchers, and it was only later that they were set down in the form we now know.Read More

Prevailing theory is that earliest humans evolved for several thousands in Africa before migrating out of Africa (In fact Africans are the most genetically diverse group, as can be seen in the difficulty matching HLA identical donors among Africans – as different African tribes have separated from each other many thousands of years ago. Humans elsewhere in the world all came from just from one small group of ancestors who left Africa about...Read More
