Credit: University of Copenhagen Is there a lottery ticket that always wins? So goes the popular version of a theoretical conundrum posed in 1969 by English mathematician Adrian R.D. Mathias within the field of set theory, an area dealing with infinity in mathematics. The problem remained a mystery throughout the 70’s, 80’s and 90’s, as…

## Sum of three cubes for 42 finally solved—using real life planetary computer

Hot on the heels of the ground-breaking ‘Sum-Of-Three-Cubes’ solution for the number 33, a team led by the University of Bristol and Massachusetts Institute of Technology (MIT) has solved the final piece of the famous 65-year-old maths puzzle with an answer for the most elusive number of all—42. The original problem, set in 1954 at…

## Mathematicians develop new statistical indicator

Credit: CC0 Public Domain Most of us know this phenomenon only too well: when it’s hot outside, you feel the urge for a cooling ice cream. But would you have thought that mathematics could be involved? Let us explain: The rising temperatures and rising ice consumption are two statistical variables in linear dependence; they are…

## Animal collectives like ants should move through their environment like ‘savvy gamblers’

Credit: CC0 Public Domain Many animals have to move around in their environment to find resources to live and reproduce. Scientists have studied particular examples of this for many years but there are not many unifying frameworks to understand the general organising principles of animal movement. This is especially true for animal collectives like ant…
