Electron Wave Forms
Electron Wave Forms
A diagram showing three wave forms, or orbitals, of an electron around the nucleus of an atom. Each wave form corresponds to a different energy level of an electron. The term 'electron' was coined by physicist George Johnstone Stoney to describe a "fundamental unit of electricity." His concept suggested that the difference between gases, or their 'distinctive spectrum', lay in an electron's movement within the 'luminiferous aether' surrounding an atom.

Physics: space, time and philosophy
Physics: space, time and philosophy
Physics is the science of matter and motion, of space and time. The word comes from the Greek fusis, meaning natural things, and the aim of physics is to understand the natural world. (The earlier word 'physic' meant medicine, as in physician.) Its origins lie thousands of years ago in ancient astronomy, but for most of the intervening centuries physics was allied with chemistry, mathematics and sometimes philosophy, into a discipline called 'natural philosophy', separating into distinct subjects about 1800. (Although, a physics professorship at TCD is still called the 'Erasmus Smith Chair of Natural and Experimental Philosophy'.)

Chemistry and Electricity
In the 1830s, the modern induction coil and a powerful and cheap new battery were invented by an unusual Catholic priest from Co Louth. Rev Nicholas Callan (1799-1864) was professor of natural philosophy at the Catholic training college, St Patrick's College Maynooth. His work spanned physics and chemistry: as well as his battery and the induction coil, he invented a way of protecting metals from corrosion and made it into the Encyclopaedia Britannica when he built what was then the world's most powerful electromagnet. Images: (right) Callan's induction coil incorporated miles of wiring and could generate an estimated 600,000 volts (left) An original Maynooth battery (© National Science Museum, Maynooth)
