A decades-old geometry puzzle has finally been solved by a young mathematician in South Korea. Hidden behind a simple hallway ...

In the 1820s, Louis Braille devised a raised-dot system of letters, numbers and musical notation. 200 years later, it’s still ...

Abstract: The present paper deals with WEB-based notation, which implements a natural language representation of mathematical texts and preserves their semantics. We have developed a visualization of ...

Long before anyone wrote down a number, early villagers were painting flowers with a precision that looks suspiciously like ...

Enlightening Symbols is mostly a historical study of the mathematical symbols we encounter in school arithmetic and elementary algebra, informed by a larger interest in the formidable utility ...

A pilot version of the compiler MIRFAC, now in the operation, is described. The chief features of the system, which is intended for the solution of scientific problems, are the presentation of ...

An ellipsis, \ldots, can be read as “and so on.” For example, 1, 2, 3, \ldots, 100 denotes the list of all numbers from 1 to 100, and 1 + 2 + 3 + \dots + 100 denotes the sum of all integers from 1 to ...

THE subject of establishing a better understanding between mathematical workers and printers has for some time engaged the attention of the council of the Royal Society. It is desirable that the ...

Royalty-free licenses let you pay once to use copyrighted images and video clips in personal and commercial projects on an ongoing basis without requiring additional payments each time you use that ...

because regression models proper (with one predictor) are introduced after (at least in the approach I take). It would be nice (and pedagogically easier) if one could specify a Gaussian model like so: ...

Abstract: Events are occurrences that happen in systems. Events can be chemical, which are natural phenomena studied from the chemical field. Such events modify chemical composition of substances when ...

Galileo once famously described the universe as a great book “written in mathematical language and its characters are triangles, circles, and other geometrical figures.” Unfortunately, it’s a language ...
