How did I miss that!? And, it was in 1993 the years when I was doing some mathematical physics of the chaos. Anyway, it is in probability&statistics field which I am not so good at. I'd like to read whole article, not this abstract only, to see how they did the physics experiments. But, it is for sale. Anyway. I can think of how they modelled the coin toss (probably, they used a "perfect" thin cylinder for computational simulation of the 5cent nickel coin with the same dimensions in the simulation). But, its physics experiments? I can guess only as I don't see the article. I don't think they did tossing the coin tousands and millions times, that can take a long time. Maybe, they "poured" tens of tousands of 5cent coin onto the table several times and they counted "heads", "tails" and "edges". And, they found 1 edge in 6000 tosses... ? I found this unbelievable... In my life, maybe, I've done millions of tosses and add billions of tosses I've seen by others, I've never seen any coin landed on its edge... Maybe, they got this 1 coin edge in 6000 tosses in some "perfected" lab conditions. (anyway, I may also talk about this in "coin with/out numerals" thread so that math prof whose specilazition is probability&statistics may see and explain how that experiment might be done.) Ps: I may start to collect the coin. Those coins that can land on their edges when tossed will be the coins I'll collect (lol).
Those videos showing coins landing on edges are fake. That one happened in soccer game referee's toss is not fake, but, there, the grassy ground there is soft like mud.
