Most abundant numbers are also semiperfect abundant numbers which are not semiperfect are called weird numbers.

In statistical hypothesis testing, two hypotheses are compared.

Chebyshev proved this conjecture, now called Bertrand's postulate, in 1850.

In mathematics, the continuum hypothesis is a hypothesis about the possible sizes of infinite sets.

The Mertens conjecture was proven false in 1985 by Andrew Odlyzko and Herman te Riele.

He also managed to make out individual point sources in some of these nebulae, lending credence to Kant's earlier conjecture.

The Mertens conjecture went further, stating that there would be no n where the absolute value of the Mertens function exceeds the square root of n .

However, in a 1904 paper he described a counterexample to this claim, a space now called the Poincaré homology sphere.

And in this way, you can take the guesswork out of policy making by knowing what works, what doesn't work and why.

His 1798 conjecture of the Prime number theorem was rigorously proved by Hadamard and de la Vallée Poussin in 1896.

Hadwiger's conjecture, still unproven, relates the size of the largest clique minor in a graph (its Hadwiger number) to its chromatic number.

Out of the question.

Many of them follow nothing but illusion yet illusion cannot replace the reality. God verily knows what they do.

The Poincaré sphere was the first example of a homology sphere, a manifold that had the same homology as a sphere, of which many others have since been constructed.

Jakob Bernoulli's Ars Conjectandi (posthumous, 1713) and Abraham de Moivre's Doctrine of Chances (1718) treated the subject as a branch of mathematics.

It's not about foundations necessarily it's about the rest of us.

They said, It's not a matter of money. This is a religious matter.

Note that the question of being infinite is logically separate from the question of having boundaries.

As with the Hilbert problems, one of the prize problems (the Poincaré conjecture) was solved relatively soon after the problems were announced.

The question of transformation in Africa really is a question of leadership.

There's no matter of scale. It's not a question of scale, it's not a question of financial resources.

The Oriental alabaster was highly esteemed for making small perfume bottles or ointment vases called alabastra the vessel name has been suggested as a possible source of the mineral name.

It's a matter of choice.

So back to the question.

Question of scale.

This is an important matter.

So it's a matter of minutes.

It's about time.

It's out of the question.

It's out of the question.

That is out of the question.

That is out of the question.

It is out of the question.

It's out of the question!

It's a question of taste.

It's a matter of personal taste.

It's a question of personal taste.

It is a matter of taste.

It's a matter of taste.

That's out of the question.

It's a matter of time.

It's a question of principle.

It's a matter of taste.
