Although history tends to forget Doby\u2019s much-less hyped debut and subsequent stellar performance, his life, career, and path to the majors were just as interesting and courageous as Robinson\u2019s. As Dave Anderson wrote in a 1987 New York Times article, \u201cIn glorifying those who are first, the second is often forgotten \u2026 Larry Doby integrated all those American League ball parks where Jackie Robinson never appeared.

There are many different algorithms, varying in complexity and number of moves required, but those that can be memorized and used by a human typically require more than forty moves.\u00a0 It turns out though, this number is a bit high, in terms of actually using the most efficient solution for a given position on a standard Rubik\u2019s Cube.

Known as saccadic masking, it is a function of the brain protecting us from suffering through blurred images that would otherwise be produced when our eyes move or shift.\u00a0A saccade is a rapid eye movement between the places where the eye rests (called fixation points). When scanning a scene, we don\u2019t actually see everything in a continuous, smooth stream; rather, although we are unaware of the phenomenon, we actually view it as a series of discrete images (when the eye pauses at fixation points), each separated by a period of blindness&#8230;(<a href=\"http:\/\/www.todayifoundout.com\/index.php\/2015\/05\/saccadic-masking\/\">more<\/a>)<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignright size-thumbnail wp-image-49405\" src=\"http:\/\/www.todayifoundout.com\/wp-content\/uploads\/2016\/10\/Fire-Hydrant-e1357766954902-340x317-150x150.jpg\" alt=\"fire-hydrant-e1357766954902-340x317\" width=\"150\" height=\"150\" srcset=\"http:\/\/www.todayifoundout.com\/wp-content\/uploads\/2016\/10\/Fire-Hydrant-e1357766954902-340x317-150x150.jpg 150w, http:\/\/www.todayifoundout.com\/wp-content\/uploads\/2016\/10\/Fire-Hydrant-e1357766954902-340x317-90x90.jpg 90w, http:\/\/www.todayifoundout.com\/wp-content\/uploads\/2016\/10\/Fire-Hydrant-e1357766954902-340x317-75x75.jpg 75w\" sizes=\"auto, (max-width: 150px) 100vw, 150px\" \/><a href=\"http:\/\/www.todayifoundout.com\/index.php\/2013\/01\/fire-hydrant-colors-actually-mean-something\/\">Fire Hydrant Colors Actually Mean Something<\/a><\/p>\n<p>One of the first challenges that firefighters face when they arrive at a fire is finding a suitable water source that provides enough water for the type of fire they are fighting. Common sense tells us a car on fire will require much less water than a burning apartment building. There are formulas used by firefighters that will tell them approximately how much water is needed to fight a given fire (see bonus facts below).\u00a0 Fire hydrants are commonly color coded to indicate how much water a particular hydrant will provide.\u00a0 This allows for quick decision making when they are deciding which hydrant to access.\u00a0Water supply for firefighting is rated in gallons per minute (GPM) available.
