Abacus: was an early aid for mathematical computations. It importance is to aid the memory of the human in performing calculation. A skilled abacus operation can work an addition and subtraction problem of the spread of a person equipped with a hand calculation. The older abacus uses cable, thread and wooden frame while the modern abacus consists of ring that slide over the rod.

According to advance learners dictionary, science is defined as the knowledge about structure and behavior of natural and physical world, based that you can prove for example by experiment.
From the above therefore science is highly connected to various field of human endeavor. Be it medicine, pharmacy, engineering, geophysics, geology, telecommunication, computer technology and mining etc. without having a good knowledge of subject like mathematics, physics, chemistry and biology one cannot attain the above mention fields.
I intend to be a pharmacist in future. A pharmacist is trained in the study of preparation of medicine and drugs and also save an distribution of sales to hospital, chemist and the general public, this has a serious interface with science, viz the above mention science subject.
Leafs and plants when harvested are taken into the laboratories and are tested before production commences, some chemicals are also added to these drug to protect it so as to stay until it expiring date. This has to do with a lot of branches of science, other science courses all properties that are involved in the production of drugs that are to be distributed must undergo serious diagnosis. Pharmacy and medicines are professional twins. In fact most students of pharmacy and medicine offer the same course unit until a period where student are then separated to their various fields.
For the avoidance of duet science can be seen to have solved the major human problems and development. The telephone, aero plane, ship or vessels, the trains, bridges, roads, space management are all related to science achievement by mankind. It is generally believed then without science the world have been a difficult place to live.
