Exceptional Brains

Human beings are endowed with power of thinking. All this is possible due to highly evolved brain. But some of us humans are exceptional. Do they see visions? They can predict the events of future. Following are such incidences from the science field. Sir P. A. M. Dirac Sir P.A.M Dirac is considered as the greatest theoretical physicist in Britain after Newton. A stern father made him the man of few words. But this trait turned on an intense internal energy. This energy manifested in the form of beautiful equations when he married Einstein’s relativity with quantum mechanism. On the… Read More »Exceptional Brains

Why Gold has the colour it has??

Gold as everyone knows is a noble metal sought after by everyone. By being noble means it is resistant to chemical reactions like corrosion by air and water combination. The answer tothe question why it has the colour it has lies in electronic configuration of gold atoms.  Its electronic configuration is [Xe] 4f14 5d10 6s1 where Xe stands for Xenon. The outermost orbitals are 5d and 6s.  There is one electron in the outermost shell. In the geometric structure, atoms are arranged in a particular config And the lone electrons present the 6s orbitals are diffused in the lattice which… Read More »Why Gold has the colour it has??
