Coin tossing has been such an integral portion of our childhoods. We settled disputes depending on the outcomes, made decisions and even decided whose turn it was to catch us during hide and seek. Like everyone else, we believed that coin flipping was the most transparent decision maker because everyone knew that the results obtained by flipping a coin were random, still are, right?

Don't worry,these results are random if a mere human were to flip a coin, since we cannotcontrol the conditions surrounding us. But how can an expert magician do itthen?

Trust us when we tellyou that with enough practice,  any humancan get the desired outcome if they learn to throw the coin in a sufficientlyaccurate manner. Yes, you read it right! It is physically possible for anyoneto control what will turn up during a coin flip.

But strictlyspeaking in terms of physics, it might not be so. A coin landing on anyconcrete floor is extremely uncertain and can only be dubbed as Chaos. Even if one tried exacting theconditions , which is highly unlikely in humans, you still might not get thedesired results.

A number offactors contribute in making it physically unsusceptible.  The highest amongst the list being the bouncea coin experiences when you toss it. Other contributors include wind, humidity,coin volume, coin position, coin value, launch angle, vibration, release speed,air pressure, humidity, friction, temperature and an observer’s breath and evenhis footsteps.

Although the effectof all of these components does not amount to much, as singularly they areminute,  but since they are alwaysvarying, hence they partake in the outcome of the coin toss. 

Like every othersubject under the sun, this phenomenon did not go unstudied. Scientistsconducted a study in order to prove the non-randomnessof tossing a coin. This was done with the help of robots which wereprogrammed to minimize all of the above mentioned factors,  commonly dubbed as “frictional forces” in physics and kept all of the conditionsconstant.

Strangely theresults were only 80 percent asopposed to a higher value being expected.

Hence, thecorrect predictions in some instances for landing of the coin in a handconclude that;

“For tossed coins, the classical assumptions ofindependence with probability ½ are pretty solid.”

The conclusion ofthe study is in accordance with the Lawof Absolute Probability, according to which there is a 50-50 chance of a tossed coin to land in either heads or tails. What this basically means is that, you could get the sameresults while flipping a coin, but according to physics, the math of tossing acoin can be determined, yet the results are random. Thought that that kid inschool knew some way to cheat while flipping a coin? Well maybe he was justlucky.
