Today is rather special. A day like today won't come around for almost another century. Today is rare and represents a \u201cgolden<\/a>\u201d opportunity for those in the know.<\/p>\n Have you guessed it?? Well since you clicked on the title you already know the spoiler...<\/p>\n Today, 8-13-21, combines three adjacent numbers in the Fibonacci Sequence<\/a><\/strong>. The mathematically progressing sequence obtained by starting with 1 and 1, and then successively summing the prior two numbers to get the next one.<\/p>\n Example:<\/p>\n 1+1=2, 1+2=3, 2+3=5, 3+5=8, 5+8=13, and so forth...<\/p>\n Fibonacci Sequence:<\/p>\n 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, 987, 1597\u2026<\/p>\n The last time we landed on a rare fibonacci sequence was 5-8-13, and as you can see from the full sequence the previous occurrence was even further back.<\/p>\n Mathematics can be found everywhere and Fibonacci numbers are especially prolific. Let's explore its occurrences and applications.<\/p>\n Photo credit: Esdras Calderan\/wikipedia (CC BY 2.0)<\/p>\n<\/div>\n We see them in nature<\/a>\u00a0\u2013 in the spirals of\u00a0pineapples<\/a>,\u00a0sunflowers<\/a>, succulents<\/a>, and pinecones<\/a>. Look closely enough and you'll be able to see Fibonacci at work everywhere.<\/p>\n Image by Sabrina Jiang \u00a9 Investopedia 2020<\/p>\n<\/div>\n Day traders have been using fibonacci retracements<\/a> to hopefully predict inflection points in the markets. Traders will often use these tools in combination with other trading algorithms to identify potential buying opportunities and conversely signals to either sell a position or take a short position on a particular equity.<\/p>\n The Parthenon<\/a>, probably the most well known structure to use the golden ratio. The ancient greeks were known for their admiration of the mathematical constant. However, they weren't the first to apply its principles to architecture. It's believe that the Egyptians applied the ratio when building the great pyramids.<\/p>\n In the same vein as architecture, master painters<\/a> have been using the golden ratio as the basis of composition that draw a viewer's eyes into key areas of a painting, imparting a sense of emotion and story.<\/p>\n <\/p>\n Mathematically, the Fibonacci numbers have many more applications and natural occurrences. Most of which are still being discovered and proven out. For example, by proving out Zeckendorf's Theorem<\/a> you could represent all integers as Fibonacci numbers.<\/p>\n Compounding also applies to Fibonacci numbers, as can be seen in the Fibonacci sequence itself. The sequence's growth is exponential and infinite, which leads us back to why today is so rare! Due to the nature of the sequence, days like today were more numerous and closer together at the start of the century, but get scarcer and farther apart as time passes.<\/p>\n Sadly, we won\u2019t see another Fibonacci day for another 81 years in 2102.<\/p>\n So take advantage of today and enjoy the beauty of Fibonacci all around you in nature, architecture, beauty<\/a>, and art.<\/p>\nNature<\/h3>\n
