Empty space Quote by Basil Mahon
““His system of equations worked with jewelled precision. Its construction had been an immense feat of sustained creative effort in three stages spread over 9 years. The whole route was paved with inspired innovations but from a historical perspective one crucial step stands out-the idea that electric currents exist in empty space. It is these displacement currents that give the equations their symmetry and make the waves possible. Without them the term @E/@t in equation (4) becomes zero and the whole edifice crumbles.””

![“One of the chief peculiarities of this treatise is the doctrine that the true electric current, on which the electromagnetic phenomena depend, is not the same thing as the current of conduction, but that the time-variation of the electric displacement must [also] be taken into account...” quote by James Clerk Maxwell](https://sms4smile.com/quotes/img-quotes/a93/james-clerk-maxwell-10636_accounts_one-of-the-chief-peculiarities-of-this-t_567321.jpg)
