Of marriage and single life. HE that hath wife and children hath given hostages to fortune; for they are impediments to great enterprises‚ either of virtue or mischief. Certainly the best works‚ and of greatest merit for the public‚ have proceeded from the unmarried or childless men; which both in affection and means have married and endowed the public. Yet it were great reason that those that have children should have greatest care of future times; unto which they know they must transmit their

In the video “The Danger of a Single Story” filmed in July 2009 and created for TED‚ Chimamanda Ngozi Adichie focuses on the meaning of every life story behind its sense which gives an opportunity to realize the bottom of being via the truth hidden inside the words. In this case‚ being

Polymerization reaCTIONS polymers are high-molecular-weight compounds‚ fashioned by the aggregation of many smaller molecules called monomers. Ex. plastics that have so changed society and the natural and synthetic fibers used in clothing are polymers. Classification of polymers Homopolymers - consist of repeated long chains or structures of the same monomer unit. Ex. PVC(polyvinyl chloride) Copolymers - polymers that consist of more than one molecule. Trimers - molecules consisting

Chemical Reactions & Equations CHEMICAL REACTION : In a reaction when the original state of the particle changes and it cannot be reversed by simple physical means‚ this type of reaction is known as chemical reaction. Example :- Fermentation of grapes‚ burning of wood etc. In this reaction we have seen that after burning of wood‚ coal is formed and we cannot make wood from coal. PHYSICAL REACTION : In a reaction when original state of the particle can be recovered by any means then this type of

complex reactions and reaction sequences‚ where raw materials react together to give the product. Such chemical process often releases energy‚ in the form of heat‚ and the reaction is described as exothermic. Many of these reactions may also evolve gases at high rates‚ and could cause reactor over-pressure. Thermal runaway reaction Runaway reactions are thermally unstable reactions where the heat of reaction can raise the temperature of the reactants sufficiently to accelerate the reaction rate out

The Educated Single Mother “A mother is she who can take the place of all others but whose place no one else can take.” (Mermillod) This quote emphasizes one of the many meanings of the word “mother”. This quote can especially relate to single mothers. When faced with the difficulty of raising a child by yourself‚ you sometimes have to play the role of mom and dad. Mothers may never be able to fill the void of the missing father‚ but given the chances‚ they will try. To say the least‚ being a
