THE RAPE
THE RAPE : Rape is defined as a heinous crime in which an unwanted sexual intercourse/penetration is forced/coerced upon a victim without the wish/consent of the victim by an offender who could be a person known to the victim or a stranger.It is a crime even if the offender is a husband and it is a crime even if the victim did not offer resistance and it is a crime even if the victim was unconscious or conscious but under the influence of alcohol/drugs/threat/blackmail. _ Anybody can be raped including men,women,children and elderly. 91% of all rapes are committed on girls/women which will be discussed by me. Even animals like ducks/geese show rape like behavior. What the world knows is a tip of the iceberg because of the reluctance to talk on this issue and misconceptions about the rape.Rape of a woman existed in human history for thousands of years […]
THE ENERGY
THE ENERGY Energy is defined as a capacity/ability to do the work and it is measured in Joules. Power is defined as the rate at which the work is done which means work divided by time and it is measured in Watts. 1 watt= 1 joule per second. 1 Giga-joule(GJ)= 1 billion joules 1 Exa-joule(EJ)= 1 billion GJ. 31.7 watts= 1 GJ per year. 1 kilo-calorie= 4.2 kilo-joules. 1 kilo calorie is the amount of energy required to raise the temperature of 1 kg of water by 1 degree celsius. Calorie is the unit of energy in nutrition. Human being needs 2000 kilo calories of energy through food for all activities per day which is equivalent to 90 watt light bulb. Energy makes change and does things for us.Energy lights homes, cooks food,runs car/fan/AC/heater/machines/TV etc.We will go back to stone age if there is no energy. First industrial revolution was […]
THE WATER
THE WATER : Water is defined as a ubiquitous chemical substance having 2 hydrogen and 1 oxygen atoms bonded to form a molecule H2O, also known as hydrogen oxide.Deuterium is an isotope of hydrogen which combines with oxygen to form heavy water(D2O). Water is essential for survival of life as well as essential for economy,industry,ecology,climate cycle and agriculture. 60 % of human body and 80 % of human brain is water.Adult human needs 2 to 3 liters of water daily for drinking and a human can not survive for more than few days without drinking water.75 % of all people in the world are chronically dehydrated leading to day-time fatigue,cancer risk,poor mental ability and body pains.Minimum water requirement per person per day is 50 liters for drinking,bathing,cooking and sanitation.America/Canada uses 2 to 8 times more water per person than most developing nations.Civilisations have developed around water sources/rivers. Water refers to […]
THE INTELLIGENCE
THE INTELLIGENCE : Abbreviations used: IQ = Traditional intelligence quotient. EQ = Emotional intelligence quotient. Intelligence of a living organism is defined as ability to receive,understand,process, memorize,comprehend,rationalize,learn,think and judge various sensory inputs from environment in a given circumstance and come out with best possible solution to the problem posed by environment and/or perform better in environment.Humans use brain for intelligence. I will not discuss the other meaning of intelligence;the information gathering. Every scholar in psychology has defined intelligence differently and there is no consensus about definition of intelligence and so my definition is open to criticism. Even a virus shows intelligence by adapting mutation for survival. Even a bacterium shows intelligence by synthesizing an enzyme to inactivate antibiotics. For lower species, intelligence is meant for survival and reproduction but for higher species like humans, intelligence could be anything from socializing to abstract thinking to reasoning to imagination to creativity.If another […]
THE COMPUTER AND INTERNET
THE COMPUTER AND THE INTERNET: Prologue: Millions of people read my comments on internet and yet,majority of them have very little knowledge of computer/internet and hence I am posting this comments to educate them. Today,we live in computer age,the computers are found everywhere and it has created global awareness. Computer is defined as a programmable machine that computes(stores,processes and retrieves) information(data)according to a set of instructions(program). Church-Tuning theory of mathematical versatility suggests that any computer with certain minimum capacity,in principle, can perform the same task that any other computer can perform. Computers are of 2 kinds,analog and digital. Analog computer is slower,having continuous inputs and uses mechanical devices like gear/rachet/lever to perform mathematical task, for example,speedometer in a car or electricity meter in house etc.It translates variables in a given problem into analogous variations in electrical quantity like current/voltage and solve original problem by solving an equivalent problem(analog) in electrical […]
