\"Bertha_and_Carl_Benz\"The Husband and Wife Team That Gave the World the First Car, and the Road Trip That Saved it From Obscurity<\/a><\/p>\n

We may not have flying cars quite yet, but the ground-bound automobile is the world\u2019s second most popular mode of transportation (behind the bicycle). Many think Henry Ford invented the car, but that isn\u2019t correct. While Ford certainly made the automobile affordable for the middle-class, it was actually a German engineer with a familiar name that invented the first commercially available petrol-powered motor vehicle. In 1885, Karl Benz created what he later would call the \u201cMotorwagen.\u201d However, this wasn\u2019t an invention of a single man. He had help from someone else \u2013 his wife, Bertha Benz. Credited as the first person ever to take a so-called automobile \u201croad trip,\u201d she also discovered various issues with her husband\u2019s invention during the drive, coming up with some very innovative ideas in the process, such as inventing…(more<\/a>)<\/p>\n

\"shark-attack\"Do Sharks Really Not Like How Humans Taste?<\/a><\/p>\n

The idea of sharks not liking the taste of humans has been around for at least a half a century, with the first account of this notion (that we could find) appearing in a Sep. 2, 1968 edition of The Evening Independent in an article titled \u201cExpert Says Sharks Dislike Human Taste\u201d. In it, the associate curator of vertebrate paleontology at the Los Angeles County Museum of Natural History, Dr Shelton Applegate, noted that it was his opinion that swimmers generally survived shark attacks because \u201cMost of them [sharks] after they take the first bite, find they…(more<\/a>)<\/p>\n

\"girl-with-foggy-glasses\"How Anti-Fog Spray Keeps Glasses From Fogging Up<\/a><\/p>\n

The \u201cfog\u201d you may sometimes experience on your glasses or goggles occurs when atmospheric humidity near the lens condenses; this happens due to a relatively significant discrepancy between the temperature of the lens and the surrounding air. As the surface attempts to reach an equilibrium between the two temperatures, heat energy is given up; and, as the energy within the gaseous water molecules decreases, they form into tiny water droplets on your lens, otherwise known as \u201cfog.\u201d\u00a0So how do we stop the fog from forming on your glasses? There are two primary types of substances used here- surfactants and hydrophilic ingredients.\u00a0Surfactants (or surface acting agents) are a broad group of compounds that include…(more<\/a>)<\/p>\n

\"fruit-rainbow\"<\/a>Why Fruits Change Color and Flavor as They Ripen<\/a><\/p>\n

Fruits and vegetables (see: The Difference Between Fruits and Vegetables) come in a wide array of colors that change throughout their ripening process, with the brightest colors often occurring when the fruit is optimally ripened.\u00a0 But why do fruits change color at all? There are two ways to answer this question- first, looking at what\u2019s going on internally while the fruit is ripening and second looking at why these plants have evolved to do this at all, especially considering it\u2019s seemingly a massive waste of the plant\u2019s energy and resources to produce fruit of any color around its seeds. While there are many different types of fruits… (more<\/a>)<\/p>\n
