A HISTORY OF ZERO
Journal Title: Journal of Science And Arts - Year 2008, Vol 8, Issue 1
Abstract
One of the commonest questions which the readers of this archive ask is: Who discovered zero? Why then have we not written an article on zero as one of the first in the archive? The reason is basically because of the difficulty of answering the question in a satisfactory form. If someone had come up with the concept of zero which everyone then saw as a brilliant innovation to enter mathematics from that time on, the question would have a satisfactory answer even if we did not know which genius invented it. The historical record, however, shows quite a different path towards the concept. Zero makes shadowy appearances only to vanish again almost as if mathematicians were searching for it yet did not recognise its fundamental significance even when they saw it.

DILL EXTRACT AS GREEN INHIBITOR FOR THE CORROSION OF CARBON STEEL IN H3PO4 SOLUTION
The inhibiting effect of dill extract (DE) on the corrosion of C-steel in 1 N H3PO4 was studied by weight loss, potentiodynamic polarization, electrochemical impedance spectroscopy (EIS). The results showed that the inhi...
