The book “The Woman and the Car, A Chatty Little Handbook for All Women Who Motor or Who Want to Motor” (presumably extremely chatty, given the title), by Dorothy Levitt written in 1906, recommended that women carry a hand-mirror while driving as it is convenient to be able to see behind you during traffic by holding the hand mirror up.

Chelsea asks: Why are potatoes called “spuds”? Among other definitions, a “spud” is a “sharp, narrow spade” used to dig up large rooted plants. Around the mid-19th century (first documented reference in 1845 in New Zealand), this implement of destruction began lending its name to one of the things it was often used to dig up, namely potatoes. This caught […]

There are some words that change their meaning based on whether the first letter is capitalized or not. These words are collectively known as “capitonyms”. These capitonyms are particularly troublesome when they appear at the beginning of a sentence, as there is no way, based on the single word alone, to tell which meaning is being referred to. Examples of […]

The difference between bacon and salted pork or ham is primarily just the composition of the brine that is used to cure it. Brine for bacon often includes sodium nitrite, sodium nitrate, and saltpeter (for curing the meat); sodium ascorbate (for setting the color, as well as speeding up the curing process); and brown or maple sugar (for flavor), among […]

Today I found out why iodine is added to salt. Iodine first began being added to salt commercially in the United States in 1924 by the Morton Salt Company at the request of the government. This was done as a response to the fact that there were certain regions in the U.S., such as around the Great Lakes and in […]

Sirius-A is the brightest extrasolar star visible to the naked eye from Earth, being almost twice as bright as the second brightest, Canopus. Sirius-A and Sirius-B combine to form a binary system and appear as one star to the naked eye, though the vast majority of luminosity to the naked eye comes from Sirius-A, Sirius-B being a white dwarf which […]

Today I found out why black lights make things glow. Black lights are not that different from any other type of light, whether incandescent, fluorescent, or just the age old candle flame. The difference is that black lights emit most of their light waves just outside the range humans can perceive, in the Ultraviolet (UV) part of the spectrum. When […]

Myth: Proper CPR technique should include frequent use of “mouth to mouth” in between compressions. In fact, the 2010 guidelines set out by the American Heart Association (AHA) do not recommend breathing for someone while performing CPR (and not for your health, as you might think, but for the person experiencing cardiac arrest’s chances of survival). If you’re a person […]

Leaves are the food processing factories for trees. The plants use their roots to take in water and other essential nutrients. The leaves then use the water and carbon dioxide from the air, in combination with sunlight, to turn the water and carbon dioxide into glucose, also giving off the byproduct oxygen in the process. It then uses the glucose […]

The now common “Fish and Chips” combo originated in Britain around 1860. For nearly 200 years before that, fish vendors had been serving fried fish on the streets of Britain. Sometime around the mid-19th century, one of them got the bright idea to serve thick cut French fries with the fried fish, with the first known “Fish and Chip” eatery […]

Cricket was originally played with a stick that more or less looked like a hockey stick. Bowlers, at the time, typically kept the ball on the ground or at least skimmed the ground, instead of pitching the ball as they do today. As a response to the change towards pitching and bouncing the ball, in the late 18th century the straight […]

Common foods that are naturally radioactive include potatoes, bananas, sunflower seeds, Brazil nuts, and kidney beans, among others. Brazil nuts are the most radioactive by far at 6600 picocuries per kg or about 1.875 BED (banana equivalent dose). The radium in Brazil nuts does not come from especially high levels of radium in the soil where the trees grow, but […]

In 1891, Ellen Martin was the first woman to be able to vote in Lombard, Illinois. She noticed that the Lombard charter on who could vote didn’t mention gender. This charter superseded Illinois law and, thus, she was legally allowed to vote. She and 14 other women voted in the 1891 elections before the charter was promptly amended. Reference

Today I found out the can opener wasn’t invented until 48 years after the invention of the can. In 1795, Napoleon Bonaparte was having problems with his supply lines. Specifically, they were too long for the food preservation methods at the time, making it difficult to adequately supply his troops with needed food. Thus, he offered a 12,000 franc prize […]

Ben Franklin fought hard for the Turkey to become the nation’s official bird, but he obviously lost out to the supporters of the Bald Eagle. His case for the Turkey being the national bird on the Great Seal is laid out in the following letter to his daughter Sarah Bache: “For my own part I wish the Eagle had not […]

Negative forty degrees is the temperature where the Fahrenheit and Celsius scales correspond with one another (-40°F = -40°C). Forty is also considered a semi-perfect number owing to the fact that a subset of its divisors added together gives 40 (i.e. 1, 4, 5, 10, and 20). Reference
