Welcome to the flysky's pages!

The first flysky's aim was to write about management, since he believes that he have collected reach experience working for several different organizations, including wide range of their type. However, very soon after his first work (on how to effectively manage a meeting), his inspiration for writing increased and he started to write about another his passion. Flysky really like travelling and sometimes it is so inspirational that he write a travel article.

Finally, as a scientist flysky turns to subjects related to mathematics and physics...

    Mild and Wild Randomness (normal distribution vs Cauchy distribution)

    3 years ago

    There are two especially different types of randomness! For the type we get used on, the law of large number holds and we have macroscopic certainty. However, this is not always a case. For so-called wild randomness fat...
