title: Teaching electric field topic with computer visualization

authors: Talele, Sadhana

subjects: electric field lines

abstract: Electromagnetic field is undoubtedly one of the most difficult course in the undergraduate courses for electronics/physics degrees. The difficulty arises from the fact that electromagnetic fields are not visible unlike some other concepts in mechanical engineering where one deals with concrete objects. Students generally find it hard to grasp the ideas as these ideas are abstract and their learning cannot be supported through simple experiments in which they can handle objects and see what is happening.
Visualisation of electric field lines and equipotential contours in several different scenarios can be demanding to imagine. There are mathematical ways to calculate however these methods can be equally or more challenging.
For the first instance before mathematics of the electric fields is introduced if the electric field lines can be viewed as an output of a simple computer model it can be very beneficial to students for their understanding and retaining/creating their interest and enthusiasm in the subject. Since several parameters in the model can be changed very easily, effects of those parameters on electric field lines can be viewed. The main objective of this article is to demonstrate some such simple modelling possibilities using the available software package.

title: The drink problem in the Te Aroha district

authors: Hart, Philip

abstract: This paper deals with the downside of drinking alcohol, not with its pleasures experienced by those indulging. Public drunkenness was always deplored, in part because it led to accidents and to criminal behaviour, in particular violence. Details of who became drunkards is given, with examples of some notable drunkards, one of them a leading businessman, and also of how women were affected by having drunken husbands. And two female drunkards are included.
To control drunkards, prohibition orders were sometimes issued, but the thirsty had various ways of evading these. Sly grog seems to have been a minor problem, perhaps because there were so many hotels. Details are given of these and how they were conducted, along with accounts of the lives of several prominent publicans, some of whom became a prey to intemperance, an occupational hazard with significant consequences for their health.
Because polite members of society and those suffering from drunkards wasting their family’s money were appalled by the behaviour described here, a strong temperance movement developed in response.
