The 3 most important inventions from the Gilded Age are the telephone‚ the lightbulb‚ and the skyscraper. The telephone‚ created by Alexander Graham Bell in 1875‚ had the ability to connect two people from a given distance together. Evolving from the human messenger and telegraph‚ the telephone improved upon those by ameliorating its speed and comprehensibility. As a result of this creation‚ people‚ today‚ can connect to each other from anywhere in the world‚ thus uniting those could never have otherwise

Characteristics and Nature of Waves In physics‚ a wave is a disturbance that travels through space and time‚ usually accompanied by the transfer of energy. Waves travel and the wave motion transfers energy from one point to another‚ often with no permanent displacement of the particles of the medium—that is‚ with little or no associated mass transport. They consist‚ instead‚ of oscillations or vibrations around almost fixed locations. For example‚ a cork on rippling water will bob up and down

"Necessity is the Mother of Invention" The quote‚ “Necessity is the mother of invention‚” is a pretty well known saying. Like most quotes‚ they can have different meanings for different people. To me‚ this quote means that without ever having to need anything‚ nothing would have been invented. Without necessity‚ the need for new inventions‚ such as the fire or even the television‚ may have never been found or even thought of. Also‚ with the need of certain things‚ you can help improve your life

Man’s Greatest Invention Man’s greatest inventions will be the topic of this journal. Although‚ inventions may or may not come in a man-made object but it does come from the work of man’s intelligence and determination to survive in this world as described in Maslow’s “Hierarchy of Needs”. This paper will express the source and significance of the Fertile Crescent to man’s greatest intellectual inventions‚ and explain why certain countries prosper and other countries were unable to develop during

dynasty inventions that have been famously credited to this period. These inventions have in one way or another shaped the way our world is lived in right now. The first and perhaps the most popular is the invention of the paper making process during the Han dynasty. Although historians claim that the oldest piece of wrapping paper can be traced back to the Chinese during the 2nd BCE‚ the process of making paper was invented during the Han period. The eunuch Cai Lun was credited for this invention. His

Physics Moment of a force: Moment of a force = force x perpendicular distance of the line if action if the force from fulcrum Law of moments: When a body is in equilibrium the sum of the clockwise moments about any point equals the sum of the anticlockwise moments about the same point. Centre of mass: Centre of mass is the point where whole mass of the body assumes to be concentrated. II. If the vertical line through the centre of mass is outside the base it will be a topples but if it’s passed

technologies. And that’s why new inventions are made every day. Actually‚ there are people who would challenge even the seemingly obvious statement that “Necessity is the mother of invention”. They say that inventions were not inspired by the necessity alone. Curiosity was‚ and still is‚ a powerful stimulus for explorers‚ researchers‚ and inventors. Besides‚ I have heard more than once‚ sometimes as a joke‚ the idea that laziness is the mother of invention‚ as the man by nature has always been
