Why Do We Measure Engines in Terms of Horsepower?

From your car, to your lawn mower, to your snow blower, to your chainsaw—the power of almost every engine you deal with is measured in terms of horsepower. None of these things seemingly have anything to do with horses, so where did that measurement come from?

Well, actual horses. In the early days of the steam engine, inventor and engineer James Watt made some significant improvements to the Newcomen steam engine, and attempted to market and sell his new version. This was easy enough when Watt was dealing with people who already had a Newcomen engine, and could directly compare the output of the old engine to his models. Some potential customers didn’t have a steam engine at all yet, though, and were still using draft horses to move weight and power machinery. He needed a way to explain his engine in terms that these people would understand.

He worked out the idea of horsepower while watching some draft horses lift coal at a mine (in some versions of the story, he watched a horse turn a mill wheel). He determined that a horse could do 33,000 foot-pounds of work in a minute (for example, move 330 pounds of coal 100 feet in a minute, or haul 33 pounds of coal 1000 feet in the same time), and dubbed that “one horsepower.” He then used that as a way to make the apples-to-oranges comparison between horses and his machinery, and could say that a steam engine had power equivalent to X number of horses.

A brief history of Clue

'Clue' Vintage Bookshelf Edition.
WS Game Company.

Originally titled Murder!, Clue was created by a musician named Anthony Pratt in Birmingham, England, in 1943, and he filed a patent for it in 1944. He sold the game to Waddington's in the UK a few years later, and they changed the name to Cluedo in 1949 (that name was a mix between the words clue and Ludo, which was a 19th-century game.) That same year, the game was licensed to Parker Brothers in the United States, where it was published as Clue. Since then, there have been numerous special editions and spinoffs of the original game, not to mention books and a television series based on it. Most notably, though, was the cult classic 1985 film Clue, which featured Eileen Brennan, Tim Curry, Madeline Kahn, Christopher Lloyd, Michael McKean, Martin Mull, and Lesley Ann Warren.

As you probably know, every game of Clue begins with the revelation of a murder. The object of the game is to be the first person to deduce who did it, with what weapon, and where. To achieve that end, each player assumes the role of one of the suspects and moves strategically around the board collecting clues.

With its emphasis on logic and critical thinking—in addition to some old-fashioned luck—Clue is a masterpiece that has stood the test of time and evolved with each decade, with special versions of the game hitting shelves recently based on The Office, Rick and Morty, and Star Wars.

Systemic vs. Systematic: How to Use Each Word Correctly

The English language is bursting with pairs of words so similar you might think they mean the same thing, even if one has an extra syllable in the middle. Some actually do mean the same thing—disorientated, for example, is a version of disoriented more commonly used in the UK, but they both describe someone who’s lost their bearings.

Others, like systemic and systematic, have different definitions. According to Dr. Paul Brians, a former Washington State University English professor and leading authority on grammar, systematic relates to an action that is done “according to some system or organized method.” If you sort your M&Ms by color and eat the blue ones last, you’re doing it systematically. Sometimes, Brians explains on his website, systematic is used when a behavior—however unintentional it may be—is so habitual that it seems to be the result of a system. If you forget to lock your front door every time you leave the house, someone might say that you have a systematic pattern of forgetfulness.

Systemic, meanwhile, describes something that happens inside a system or affects all parts of a system. It’s often used in scientific contexts, especially those that involve diseases or pesticides. If a cancer is systemic, that means it’s present throughout the body. If you’re describing how the cancer progressed, however, you could say it spread systematically from organ to organ. As Grammarist points out, systemic can also denote something that is “deeply ingrained in the system,” which helps explain why you sometimes hear it in discussions about social or political issues. When Theodore Roosevelt served as the New York City Police Commissioner, for example, his main goal was to stamp out the systemic corruption in the police department.

In short, systematic is used to describe the way a process is done, while systemic is used to describe something inside a system.
