    Speaking of coincidences-the other day, I was playing cards with some friends. We took turns shuffling the deck. When I shuffled the deck, it turned out that I had ordered the cards into a very rare sequence. That sequence that had an _a priori_ probability of less than *one in 80 unvigintillion* - that's 8 followed by 67 zeros. That probability is about the same as tossing a 6-sided die 87 times and getting a 6 every single time. And I had done it in just one attempt!
    That's not all. Over the course of the evening, I must have shuffled the deck some 20 times. Each time-believe it or not-the sequence of cards-though different each time-had that same extremely low probability of existing! And yet, I did that 20 times without fail. 🤯
    Wait till I tell you about the time I played darts in a pub ...

    About the upcoming 14th May lecture _"How to prove 1 = 0"_ - I'd do it by insidiously dividing by zero. Alternatively, I'd reorder or regroup the terms of a series that doesn't converge absolutely. Am I right? Am I RIGHT???

    Six degrees of separation can happen in social networks (not random graphs) precisely because you don’t pick someone randomly but on purpose.

    Check it, how many people, people generally know between 30-137 people.
    Humans are not built to remember more people than that.

    I understand enthousiasm and being nervous but lovely lady Hart, if you learn to breaaaathe and pause while talking, you sound less out of breath and your words come across better.
    Other than that, a very interesting talk which invites to dive deeper in the matter.

    This woman is insufferable. It requires a talent to explain basic or semi-basic concepts and she obviously lacks it

    Can I say it? Awkwardly? *Randomly, we only know between 30-137 people.
    We tend to blur the rest,
    People don't know 1000 people.

    The chances of his being hit by lightning are known: the probability is exactly 100%.
    You're welcome.
    Next question.

    Well. Being born is 1 in 100-200 million chance.
