Not sure it's delusional. They're just going to say whatever they need to say. I doubt he really believes what he is saying. But they definitely want Ukraine under their control.
A lot of schools/universities were using zoom as well. I think it has to do with the fact that you don't need an account to log into a room. So minimum amount of work to get kids into the conference room.
Given the millions of species that have ever existed on earth, there is only one that has been remotely capable of what humans can do. So add that as another 1 in a million factor. But I guess when we're on the order of 10^20 planets, maybe 1 in a million factored in really is meaningless.
At the same time, I think most people would be underwhelmed if the universe was teeming with bacterial life. What people really want to know is if intelligent life exists elsewhere in the universe.
I just tried to google mātauranga Māori and on first pass I can't find any description of what it actually is. Sounds like a bunch of mumbo jumbo to me.
I'm not sure which test is the best to use, so I just start with a divergence test
##\lim_{n \to \infty} \frac {n+3}{\sqrt{5n^2+1}}##
The +3 and +1 are negligible
##\lim_{n \to \infty} \frac {n}{\sqrt{5n^2}}##
So now I have ##\infty / \infty##. So it's not conclusive. Trying ratio test...
