We all get bored at some point. One survey found that the average American adult experiences 131 days of boredom per year. And most of it happens at work.Another study revealed that employees are ...
This is a timeline of pure and applied mathematics history.It is divided here into three stages, corresponding to stages in the development of mathematical notation: a "rhetorical" stage in which calculations are described purely by words, a "syncopated" stage in which quantities and common algebraic operations are beginning to be represented by symbolic abbreviations, and finally a "symbolic ...
In ten minutes, he answered, 34,588,806. The difference of time between his answering this, and the two former questions, was occasioned by a trifling mistake he made from a misapprehension of the question. Despite Fuller's perfect answers, it appeared to Hartshorne and Coates that his mental abilities must have once been more extraordinary.
A property of weird numbers is that if n is weird, and p is a prime greater than the sum of divisors σ(n), then pn is also weird. [4] This leads to the definition of primitive weird numbers: weird numbers that are not a multiple of other weird numbers (sequence A002975 in the OEIS). Among the 1765 weird numbers less than one million, there are ...
Here’s another fun fact: every time you learn something, your brain is never the same again. It physically changes whenever you gain new information, skills, or experiences.

Since the former describes the class of problems termed NP, while the latter describes P, the question is equivalent to asking whether all problems in NP are ...
