Wow Purplebee, that is a very philosophical question!
Luck is based on chance.
For example, if you flip a regular coin, there is an equal chance of you getting one side of the other. But if a wind blew or you stuck something to one side, the chances would change in favour of one side. If you knew the effect these things have on each side, your luck of picking one side or the other could change.
Others things are not up to chance like this. You passing your test in class is not up to luck really, it’s down to you studying for the questions right? The type of question the teacher asks, though IS ‘chance’ and if you know enough about this chance, then your ‘luck’ would change, not because of something magical, but because you understand the subject better and so can answer any question she asks!
It’s a little sad to think that luck might not be around, but if you know enough about something, pretty much anything can be predicted! The only things I can think of that can’t be predicted with enough information is the position of tiny little particles which make up the world, called electrons. This is mind-bending because everything is essentially made of this, so basically everything is really organised randomness!
If you mean supernatural influence on real life then I would say no. However I do believe that it is a real psychological effect that affects people, even scientists! As a psychological support, in difficult moments, we do need little talismans, a favourite tshirt or a pen, or we have some daily rituals that we have to respect. I must admit that even if I’m a scientist, I do believe that this psychological bad good luck has a powerful effect in my life!
Black cats, ladders, and other such superstitions can really affect people lives, but I think it s more psychological than anything else. Lottery wins and coin tosses are all about probability. You have one in two chances of guessing the right face or tail on a coin. And your chance of winning the lottery depends on how many people purchase lottery tickets. That’s maths creeping into our lives again. Great stuff! And Great question purple bee! I reckon you ll make a great scientist 🙂
