Story of Superconductivity: A Serendipitous Discovery
Electricity is carried through metallic wires, called conductors.In the process, electrons move through metallic conductorsthat offer resistance (the value depends on the particularmetal used), to the passage of electrons. This leads to the productionof heat and loss of energy. This heating process isutilised in many electrical devices. However, for transmissionof electrical energy from the power plants to the user and inmany other applications, it would be a great boon if no energywas lost to resistance. The discovery of superconductivity byHeike Kamerlingh Onnes in 1911 at Leiden, offered a glimmerof hope to make this dream possible. It was a discoverytotally unexpected at that time, and we owe this discovery tothe painstaking andmethodical investigations of Onnes – firstto produce very low temperatures, and then measure propertiesof materials at these freezing temperatures.

The Experiment of Michelson and Morley: Experiment That Ruled Out Ether
Light was assumed to propagate in a medium called etherwhich was all pervading and stationary. Earth’s motionthrough ether was expected to have an effect on the velocityof light in the direction of the relative motion by the law ofaddition of velocities. Michelson–Morley experiment used aninterferometric technique to detect this effect and got a nullresult, which was the first strong evidence against existenceof ether and eventually had a natural explanation in specialtheory of relativity.
