The word random means unable to predict or occurs without a set of patterns. When rolling dice the results will be random. A simple coin toss also has a random output. Atmospheric noise produces random. When we think about random what comes into mind is out of the blue human behavior that is arbitrary. That however isn’t true random. If one could delve into another’s thoughts than what that person is about to say wouldn’t be unpredictable anywhere.
But then again, is anything truly random? Dice isn’t impossibly unpredictable. If the angle of which the dice was thrown from, wind speed, bounces and all the other factors were calculated then predicting the numbers that showed up would be a breeze. Only the lack of information causes a certain event to be random or unpredictable.
Even computers when asked to generate random numbers would do so in a way that it’s called pseudorandom, an event that seems random but is not. Random is essential in cryptography where an unpredictable number is needed to secure itself from attackers-howtogeek.com. In order to generate a good distribution of numbers without repetition a coding formula is used and without the formula and a seed it is fairly improbable to predict-howstuffworks.com
Nature itself is not random. For sunlight efficiency and space the leaf arrangement of a plant follows the Fibonacci sequence (1,1,2,3,5,8…). Pinecones, pineapples, fruits, the seed arrangement of a sunflower, a seashell are also under influence of the sequence.
In order to find true randomness we must delve into quantum mechanics. According to Wikipedia to measure precisely when a single atom will decay is impossible; in other words truly random. Calculating the rate of decay for many atoms uses the half life formula.
