What do we know about monkeypox, what do we not know, and what efforts are going into modelling it?

The COVID-19 emergency resulted in some amazing mathematical collaborations.

Here's a simple game at which a human can out-fox even the cleverest algorithm.

The INI is celebrating its 30th birthday. What is it and what is it do for maths and mathematicians?

The sampling distribution, i.e. the distribution of the means of the individual samples is NOT the normal distribution, as this blog states. The sampling distribution is the so-called Student t distribution, which, although similar in shape to the normal (Gaussian) (bell-shaped) has different parameters. In particular, normal distribution does not depend on the sample size while the Student t distribution does (sample size / degrees of freedom is a parameter of Student t). The spread of normal is characterized by variance (standard deviation squared) while the spread of Student t is characterized by the standard error squared.
