What Use In Maths In Everyday Life?“Maths is all around us , itseverywhere we go”. It’s a lyricthat could go easily have beensung by wet wet wet. It may nothave made it onto the fourwedding soundtrack, but it,certainly would have beenprofoundly true.

Mathematics is in principle inexpensive. As the old joke says, amathematician needs only paper, a pencil, an easy chair and a wastebasket. Also, the criterion for success in mathematics is by and largeuniversally accepted. This makes mathematics an attractiveinvestment. Moreover, a mathematical result is valid forever. It mayfall out of fashion, or fall outside the current area of application, buteven the oldest known mathematical formulae - such as that forsolving quadratic equations, known 2400 years ago by Babylonians,Chinese and later the Greeks before being crystallized into its presentform in 1100 AD by a Hindu mathematician called Baskhara - are thebread and butter of present-day elementary mathematics.

Alas, the downside is that the results are usually not immediatelyapplicable – and therein lies the risk. Who wants to invest insomething that may not lead to applications for several hundred years?The good news is that the distance between theory and application isbecoming shorter and shorter.Mathematics can be compared to a pyramid. On the top of the pyramidare applications of mathematics to health, weather, movies and mobilephones. However the top of this pyramid would not be so high if itsbase were not so wide. Only by extending the width of the base can weeventually build the top higher. This special feature of mathematicsderives from its internal structure. A good modern application ofmathematics can typically draw from differential equations, numericalanalysis and linear algebra. These may very well draw from graphtheory, group theory and complex analysis. These in turn rest on thefirm basis of number theory, topology and geometry. Going deeper anddeeper into the roots of the mathematics, one ends up with suchcornerstones of logic as model theory and set theory.

It is clear that mathematics is heavily used in large industrial projects and in theever-growing electronic infrastructure that surrounds us. However, mathematicsis also increasingly infiltrating smaller scale circles, such as doctors receptionrooms, sailboat design and of course all kinds of portable devices. There has alsobeen a change in the way mathematics penetrates our society. The oldestapplications of mathematics were probably in various aspects of measurement,such as measuring area, price, length or time. This has led to tremendouslysuccessful mathematical theories of equations, dynamical systems and so on. Intodays world, we already know pretty accurately for example the make-up of thehuman genome, yet we are just taking the first steps in understanding themathematics behind this incredibly complex structure of three billion DNA basepairs.

Our understanding of the mathematics of the whole universe ofheavenly bodies, even going back in time to the first second of itsexistence, is better than our understanding of the mathematics ofour own genes and bodies.What is the difference between the hereditary information encodedin DNA and the information we have about the movements of theheavenly bodies? Is it that we have been able to encapsulate thelatter into simple equations, but not the former? Or is it perhapsthat the latter has a completely different nature than the former,one that makes it susceptible to study in terms of equations, whilethe former comes from a world governed by chance, and algorithms,a world of digital data, where the methods of the continuous worlddo not apply?

In this mathematical projects that are in some way relevant,directly or indirectly, to our everyday lives. We start with projectsthat have apspecial issue on Mathematics for Everyday Life, wepresent a selection of plications in the health sector and continuewith the closely related topic of image processing. We then go on tothe timely topic of weather (one of the prime examples of large-scale computing), the effects of which are immediately felt whenthe beach turns into a swamp, contrary to the weather report. Wepresent three projects in transportation, one on ships, one on trainsand one on cars. In the section on society we touch upon topics likerating, trading and immigration. We also include two articles onthe topic of matheticmatics education. The special issue ends withan article on a little mystery inside mathemas.

Aryabhata (476-550 CE) was the first in the line ofgreat mathematician- astronomers from the classicalage of indian mathematicians and indian astronomy.His most famous works are aryabhitiya (499 CE, whenhe was 23 years old) and the arya- siddhanta .Aryabhatta mentions in the aryabhitiya that it wascompose 3,630 years into the kali yug, when he was23 years old. This corresponds to 499 CE and impliesthat he was born in 476.
