Smoke is a collection of airborne solid and liquid particulates and gases[1] emitted when a material undergoes combustion or pyrolysis, together with the quantity of air that is entrained or otherwise mixed into the mass.
It is commonly an unwanted by-product of fires (including stoves, candles, oil lamps, and fireplaces), but may also be used for pest control (fumigation), communication (smoke signals), defensive and offensive capabilities in the military (smoke-screen), cooking, or smoking (tobacco, cannabis, etc.).

Book design is the art of incorporating the content, style, format, design, and sequence of the various components of a book into a coherent whole.

To produce perfect books, these rules have to be brought back to life and applied."
Front matter, or preliminaries, is the first section of a book, and is usually the smallest section in terms of the number of pages. Each page is counted, but no folio or page number is expressed, or printed, on either display pages or blank pages.
The principal element of Suprematism in painting, as in architecture, is its liberation from all social or materialist tendencies. Through Suprematism, art comes into its pure and unpolluted form.

Here's to the crazy ones. The misfits. The troublemakers. The ones who see things differently. You can quote them, disagree with them, glorify or vilify them. About the only thing you can't do is ignore them.
