Cosmology/Cosmetology

June 21, 2011

The universe. Vast and indifferent.

Cosmology is the study of the cosmos – all the stuff in the universe, including stars, planets and galaxies.

Cosmetology is the art of cosmetics.

 
 

One way to remember the difference: cosmetology takes its name from “cosmetics,” while cosmology sounds like “Cosmos,” the great series from cosmologist Carl Sagan.

You could say that cosmetologists and cosmologists both study the makeup of the stars.

You could also say that both carry an air of the “Dark Arts,” relying on esoteric formulas and theories that are difficult to understand, let alone observe. This makes both fields susceptible to quackery, from folks trying to prove the existence of UFOs or a secret formula to look young.

    Job Descriptions

Cosmologists look at the practical dynamics of the universe, such as planetary mechanics, plasma physics, astrophysics and cosmic microwaves. They may examine theoretical aspects of their science, like whether the universe is expanding, and how old it is.

Cosmologists earn master’s or doctoral degrees before joining the workforce. At universities and laboratories, they teach, analyze data and develop models to explain the forces at work in the heavens and what it all means here on earth. Their observations and discoveries affect astronomy and physics.

Cosmetologists go to beauty school. They take courses in shampooing, eyebrow shaping, cuticle management and sales techniques, for example.

It can be a long haul from signing up for beauty school and earning a living at it; cosmetology is a licensed profession in most North American jurisdictions. In Ontario, would-be cosmetologists study for 3,500 hours, including a lengthy apprenticeship, before they can even take the licensing exam.

Job titles for cosmetologists include esthetician, barber, pedicurist, hairstylist and appearance coach. In the Toronto area, the average wage for this job category is $12.30/hour. Tips are a significant source of income.

Cosmologists may be members of a faculty, but are not, strictly speaking, “licensed” or regulated. In Canada, their job category comes under “physicists and astronomers.” The average wage is about $40/hour.

 
A Brief Cosmology Timeline:

500 – 300 BC – People start to wonder what causes the regular movement of planets and stars in our solar system. Observation and mathematics further the revelation that the sun is at the centre.

1401 – 1464 – Nicholas de Cusa develops the idea that every star is a distant sun.

1543 – Copernicus and others work out models that explain the motion of objects in the known universe.

1687 – Additional natural laws, including universal gravitation and early physics are developed by Newton.

1905 – Albert Einstein’s Special Theory of Relativity is published, offering a time-space continuum.

1950 – The Big Bang Theory.

2006 – Cosmologist take heart when Big Bang scientists earn a Nobel Prize in physics. “Not only did it enable all kinds of science,” said Mike Turner, a University of Chicago cosmologist in an NPR interview, “I think it got us respect.”
 

A Brief Cosmetology Timeline:

10,000 BC – People use scented oils to disguise body odor. Cosmetics are applied to signify group allegiance and standing, or to mark special occasions. Colour, either temporary or tattooed beneath the skin, decorates their bodies.

2011 AD – People use scented oils to disguise body odor. Cosmetics are applied to signify group allegiance and standing, or to mark special occasions. Colour, either temporary or tattooed beneath the skin, decorates their bodies.
