$Elementary considerations led me to the conclusion that a medium, composed of layers of different dielectric constants, must behave as a uniaxial crystal if it is assumed that the layer thicknesses are only a fraction of a wave-length. (Karl Ferdinand Braun)$

Elementary considerations led me to the conclusion that a medium, composed of layers of different dielectric constants, must behave as a uniaxial crystal if it is assumed that the layer thicknesses are only a fraction of a wave-length.

Oliver Lodge

People behave differently to TV stars and film stars; it's to do with the scale of the medium. Film stars get hushed awe, TV stars get slapped on the back. Neither is good for you. Famous people don't hear the word 'no' enough.

Tom Hollander

The fundamental division of forms of life on Earth is not that between plants and animals, as is commonly assumed, but between prokaryotes-organisms composed of cells with no nucleus, that is, bacteria-and eukaryotes-all other life forms.

Lynn Margulis

Discover how Kapoor's continual experimentation with structure and medium has led him to work with a wide variety of materials from clay, fibreglass and paint pigment, to steel and wax, creating beautiful, strange and intriguing works that counter conventional ideas of art.

Anish Kapoor

Every medium has its advantages and weaknesses and there are many things I can put down on paper that I might not be able to put into film or into a stage performance. In each form, one can communicate powerfully in different ways.

Lawrence Wright
