The domestic dog (Canis lupus familiaris) is generally considered as a sub-species of the wolf (Canis lupus).
The wolf itself has several sub-species: Timber Wolf (Canis lupus lycaon), Arctic Wolf (Canis lupus arctos), European Wolf (Canis lupus lupus), the archetypal Grey Wolf (Canis lupus), and more.
And, of course, there are many different breeds of the domestic dog, from the Chihuahua to the St. Bernard.

My question is:
If the Chihuahua and St. Bernard are physically incapable of mating with each other, due to the difference in size, can they be considered to have speciated?

Pi is an irrational number so it has an infinite number of digits. So is it absolutely certain that every sequence of digits occurs somewhere in pi?

Is there a string of one hundred straight 5's somewhere?
Without computing pi to trillions of digits, can it be proven that it contains this sequence of digits?

Parts of my body give sign as to what will be going to happen - if right sides of my body (any parts like eyelids, arm, leg, chest etc) flutters then something good happens always. And vice versa. For example if left side of my back flutters then I know I am not going to have a good sleep in the night. And it happens so. Or say my right leg flutters, then for sure I will go for a pleasant journey. My right eye flutters and I am sure to get some good news. My left side lip flutters and I am going to have a fight. Is this what is called sixth sense?

Do you think that one day someone will find a polynomial type formula that predicts the nth prime number? Or is there no pattern to them.

This question stems from the need to understand how is ti that women who endure as much as men do to obtain MD status and work hard and long hours...get paid any less? Does this result from a belief that women underperform men?


And does this disparity hold true for male vs. female nurses? Male vs. female PAs? Other HCPs?
