A Heavenly Perfume
In Egypt, Persia, and Japan, orris powder was made from the dried root of the iris and used prodigiously in the art of perfumery. Orris has an odor not of iris but of violets. Until the recent development of chemical scents, most violet-perfumed products were made from orris, it being cheaper to produce than violet extract. Orris also has the ability to strengthen the odors of other perfumed substances and has been used for centuries as a fixative in the manufacture of powders and perfumes.
Orris came to prominence in Europe during the excesses of the French court prior to the Revolution. It was used to mask the unpleasant smells of stale body odor prevalent in high society, since bathing was considered unhealthy. One story tells of an argument between Louis XIV and his mistress Madame de Montespan that concluded with the lady telling the king that, for all her faults, she didn’t smell as badly as he.
Orris powder was employed to scent and preserve the odoriferous and often lice-infested coiffures of the French aristocracy. Orris was mixed with flour to make a stiffener, so that the hair could be molded into fanciful sculptures studded with ribbons, pearls, beads, and artificial flowers.
Large quantities of Iris germanica var. florintina are grown in Mexico today for their roots, which are shipped to France for use in the cosmetic industry.
Why does passing an electric current through the metal filament of a light bulb produce light?
The explanation is that the electrical energy makes the electrons in some of the atoms of the filament metal jump outward to an orbit with a higher energy level. This higher orbit is unstable, and after a while the electron will pop back into its original orbit; when it does this, it emits energy in the form of light.
Why people object to using animals for medical research. First, medical research improves our understanding of disease and disease prevention.
This provides the foundation for the effective treatment of disease and the saving of lives. Even though animals might suffer, researchers are always trying to minimize that suffering. If there was a choice between using animals in medical research and saving human lives, or not using animals and putting human lives in jeopardy, which alternative do you think most people would support?
It is often said that natural peanut butter is a better option than processed peanut butter for those looking to lose weight. But, if you compare the number of calories in 1 tablespoon of natural peanut butter (which contains only peanuts) to that of processed peanut butter (which has sugar added), this claim comes into doubt. Kraft processed, whipped peanut butter has 70 calories per tablespoon; whereas, Adams all natural peanut butter has 100 calories per tablespoon. In terms of calorie consumption, natural and processed peanut butter are not much different.
