Scientist- C. F. Du Fay

  1. 1. C. F. Du FayCharles-François de Cisternay du Fay was born inFrance in 1698.He was a Parisian by birth. He started his career inthe French Army, rising to the rank or captain. He then left to become a chemist in the AcademieFrançaise and in 1732 became superintendent ofthe Jardin du Roi. He was also one of the first toinclude an electroscope in his research.He died of constipation on Thursday, July 5, 1739.
  2. 2. He discovered the twoC types of electricity:O vitreous and resinousN (positive and negativeT charge).R He noted the differenceI between electrics and non-electrics’, nowB known as conductors andU insulators.T He discovered that alike-I charged objects wouldO repel each other and thatN unlike-charged objects attract.
  3. 3. Discovery: The two types of electricity In December 1733, he noticed that objects that had been rubbed attracted and repelled each other. He proposed two different kinds of electricity to Amber(above);Gem(below) explain this phenomenon. ‘Vitreous’ (Latin meaning glass) is produced when glass or gems were rubbed. ‘Resinous’ electricity (Latin meaning resin) is obtained by rubbing amber, silk, or paper.
  4. 4. Types of Charges • He argued that objects with different kinds of electricity attract each other, whereas those with the same kind of electricity repel.
  5. 5. Values we want to learn from Du Fay• The values we would like to learn from Du Fay are his patience, resilience and passion for learning.
  6. 6. Reflection• From this assignment, we have learnt and understood the following: – A successful discovery can only be achieved with the help of many scientists. – We should not be afraid to try out new things. – It may take many years for discoveries of something to be fully completed.
  7. 7. ReflectionThroughout the assignment, wefaced many problems such as notbeing able to find the necessarydetails on the Net and not beingable to decide on what to putinto our slides. We overcamethem by replacing the insufficientpoints with other ones and takinga few moments to organize ourslides.
