Put aside formal education.

Many will argue that without education, the world would still be in the dark ages. Education is generally seen as the catalyst for development in any society. This argument fails to realize that the individuals that have advanced the world were persons that refused to conform to educational dictates. These individuals thought outside the box of conformity as presented by formal education. Formal education removes or greatly reduces a person's creative ability. It simply teaches you to believe and accept something as a fact except someone, who dares to think outside the box proves the fact otherwise. For anyone who wishes to excel in life, the one must put aside formal education and reach out into the deep reserve of creative ability on the inside.







Through education, accumulated knowledge, skills or values are deliberately passed on to another individual. Education is a process that is designed to have a formative effect on individual from a tender age. A child is thought from a tender age some societal values that are preserved and passed from generation to generation. We are thought in schools, about the gravitational force and that the earth is spherical. Depending on a person's choice of career, there are educational curriculums designed to impact knowledge towards achieving a career goal. A person is said to be formally educated after successfully completing the curriculum and passing the final examination.






To be educated therefore is to show an understanding of the subject area as put together by the teacher. Sometimes, it is a matter of 'junk-in' and 'junk-out'. Education tries to impact knowledge that is generally accepted to be true or has morale.






Formal education constrains one to figure out what someone else has done on a particular subject. It gets one occupied trying to unravel equations or to simply memorize the equation. The focus is to pass the examination at the end of the course. It reduces an individual to a mere robot: performing a third party script. Formal education does not provide much of an opportunity to use one's initiative. It destroys creativity and prevents one from utilizing this rich resource of the mind. It simply teaches to accept other persons' view on a subject.






The world is full of persons who are formally educated only to end up in some form of routine job. These are not the persons the world needs. The world needs those who have the courage to put aside formal education and to think outside the box. These are the dreamers and the inventors. To think outside the box is to tap from the potential that lies within the mind of every individual. It means being creative and original. The world does not celebrate those who are formally educated. It only celebrates those who dare to be different and think outside the box. If you wish to be celebrated, then you must put aside formal education and think outside the box.






I have come to observe that some of the greatest men and women in the world were/are persons that put aside formal education. Most of them were not formally educated. These persons refused to conform but rather reached into the deep resource of their minds to produce creative ideas that are celebrated all over the world.






The world cannot forget Thomas Edison in a hurry. He is one of the greatest inventors the world ever produced. One of his legacies is the incandescent light. Thomas suffered from partial deafness and lacked formal education. He believed that he had something to live for and reached into the deep resources of his mind by thinking outside the box.






John D. Rockefeller is believed to be the richest man in history. He had hoped to go to college but had to drop out of high school in order to work and to support his family. By the age of twenty-five years, he already had a refinery. Without formal education, J D Rockefeller assessed the great wealth of his mind to establish his great empire and to employ the educated folks.







The story of Bill Gates, the co-founder of Microsoft Corporation is known to most people all over the world because of the revolution of the personal computer. Bill had special interest in programming and would like to try new things. Although he had admission in Harvard College, he had to drop out because of his attachment to programming machine. Today, Microsoft is a house-hold name because someone refused to conform.

 



Similar story goes for Steve Jobs who was the co-founder of Apple Inc. After graduating from high school, Steve Jobs enrolled in Reed College, Portland, Oregon but had to drop out after just one semester. The success story of his inventions that include iPod, iPhone, iPad is the testimony of a man who dared to be different.







I have just mentioned some of the world greatest inventors and businessmen. The list is unending. Most of these men and women did not have formal education. They escaped the mental captivity imposed through formal education. This enabled them to reach down into the deep resource of the mind. Exploring this resource positively transforms a person into a creator. Humans are by nature creative being but this ability is hindered by the formative effect of education. Education teaches conformity. Conformity with the world is never celebrated. The world only celebrates those who are different. If you really wish to excel in life, be prepared to put aside formal education.

Michael Farady had no formal education.

Michael Faraday


The Amateur:



A guy who worked in a London book shop, with virtually no formal education.


The Accomplishment:


Revolutionized our understanding of electricity, and a whole lot more.


If you are using anything powered by electricity, if you know anything about magnetism, if you have ever used a Bunsen burner or if you are a big fan of benzene and the clathrate hydrate of chlorine (and who isn't?), then you owe some respect to Mr. Faraday. Michael Faraday was a genuine experimental genius and is considered one of the most influential scientists of all time. Oh, and he never had any formal education.






Faraday was born into a poor family in industrial London, so he never had any money to pay for a proper school. Instead, at age 14 he took an apprenticeship at the local book-binder for seven years. While he was there, he started to read some of the books that he was binding -- sort of like working in a chocolate factory and eating all the chocolate, only you don't get fired for it.


Now, having read up on a bunch of science stuff and finding himself fascinated with it, he asked London's best scientist, Humphrey Davy, for an assistant job. Humphrey declined. To be honest, Faraday was a guy with absolutely no scientific experience or education who had just asked the best chemist in the business for a job.


He did get a job in the next year though, and then shit went down. In short time, Faraday invented the electric motor, the electric generator, the Bunsen burner, electrolysis and electroplating. He discovered electro-magnetic induction, he discovered benzene, he figured out the shape of magnetic fields, discovered metallic nano-particles (thought to be the birth of nano-science) and something complicated about chlorine. Basically, he was a science machine.


Today, his legacy lives on as one of the best scientists the world has ever seen, despite having never been taught science in his life. Besides, no one could really teach him much science because he discovered most of it. Davy, the world famous chemist who turned down his initial job application, was once asked, "What was your greatest discovery?" He replied, "Michael Faraday."

Michael Faraday, FRS (22 September 1791 – 25 August 1867) was a British scientist, chemist, physicist and philosopher who greatly contributed to the fields of electromagnetism and electrochemistry. His main discoveries include that of the Magnetic Field, Electromagnetic Induction, Diamagnetism and Electrolysis.

Although Faraday received little formal education and knew little of higher mathematics such as calculus, he was one of the most influential scientists in history;[1] historians[2] of science refer to him as having been the best experimentalist in the history of science.[3] It was by his research on the magnetic field around a conductor carrying a DC electric current that Faraday established the basis for the concept of the electromagnetic field in physics. Faraday also established that magnetism could affect rays of light and that there was an underlying relationship between the two phenomena.[4][5] He similarly discovered the principle of electromagnetic induction, diamagnetism, and the laws of electrolysis. His inventions of electromagnetic rotary devices formed the foundation of electric motor technology, and it was largely due to his efforts that electricity became viable for use in technology.

As a chemist, Faraday discovered benzene, investigated the clathrate hydrate of chlorine, invented an early form of the Bunsen burner and the system of oxidation numbers, and popularised terminology such as anode, cathode, electrode, and ion. Faraday ultimately became the first and foremost Fullerian Professor of Chemistry at the Royal Institution of Great Britain, a lifetime position.

Faraday was an excellent experimentalist who conveyed his ideas in clear and simple language; his mathematical abilities, however, did not extend as far as trigonometry or any but the simplest algebra. Maxwell took the work of Faraday and others, and summarized it in a set of equations that is accepted as the basis of all modern theories about electromagnetic phenomena. On Faraday's uses of the lines of force, Maxwell wrote that they show Faraday "to have been in reality a mathematician of a very high order – one from whom the mathematicians of the future may derive valuable and fertile methods."[6]

It is said that Albert Einstein kept a picture of Faraday on his study wall, alongside the picture of Isaac Newton and the photograph of James Clerk Maxwell.[7]

Ridiculously Common Science Myths

Evolution Std.Jpg
The Myth: Evolution causes something to go from “lower” to “higher”







While it is a fact that natural selection weeds out unhealthy genes from the gene pool, there are many cases where an imperfect organism has survived. Some examples of this are fungi, sharks, crayfish, and mosses – these have all remained essentially the same over a great period of time. These organisms are all sufficiently adapted to their environment to survive without improvement.






Other taxa have changed a lot, but not necessarily for the better. Some creatures have had their environments changed and their adaptations may not be as well suited to their new situation. Fitness is linked to their environment, not to progress.
Brightest Star
800Px-Sirius A And B Artwork.Jpg
The Myth: Polaris is the brightest star in the northern hemisphere night skyThe Myth: A penny dropped from a very high building can kill a pedestrian below

Sirius is actually brighter with a magnitude of −1.47 compared to Polaris’ 1.97 (the lower the number the brighter the star). The importance of Polaris is that its position in the sky marks North – and for that reason it is also called the “North Star”. Polaris is the brightest star in the constellation Ursa Minor and, interestingly, is only the current North Star as pole stars change over time because stars exhibit a slow continuous drift with respect to the Earth’s axis.
Pennies from Heaven

Empirestatebuilding.Jpg







This myth is so common it has even become a bit of a cliche in movies. The idea is that if you drop a penny from the top of a tall building (such as the Empire State Building) – it will pick up enough speed to kill a person if it lands on them on the ground. But the fact is, the aerodynamics of a penny are not sufficient to make it dangerous. What would happen in reality is that the person who gets hit would feel a sting – but they would certainly survive the impact.
 
Lightning
Lightning.Jpg
 
The Myth: Lightning never strikes the same place twice







Next time you see lightning strike and you consider running to the spot to protect yourself from the next bolt, remember this item! Lightning does strike the same place twice – in fact it is very common. Lightning obviously favors certain areas such as high trees or buildings. In a large field, the tallest object is likely to be struck multiple times until the lightning moves sufficiently far away to find a new target. The Empire State Building gets struck around 25 times a year.
Gravity in Space
Astronaut Banjo.Jpg
Myth: There is no gravity in space
 
In fact, there is gravity in space – a lot of it. The reason that astronauts appear to be weightless because they are orbiting the earth. They are falling towards the earth but moving sufficiently sideways to miss it. So they are basically always falling but never landing. Gravity exists in virtually all areas of space. When a shuttle reaches orbit height (around 250 miles above the earth), gravity is reduced by only 10%.

Facts and Information about Aurora Borealis

Facts and Information about Aurora Borealis



Increase your knowledge of Facts about Aurora Borealis with some brief, but essential information & fast facts about this fascinating subject. Important facts, data and info containing details of the description, name origins and cause of Aurora Borealis, also known as the Northern Lights. Details of the colors, cause and definition of Aurora Borealis, the Northern Lights. A Detailed Fact Sheet covering a whole host of topics including facts about Aurora Borealis, the Northern Lights!






Aurora Borealis






The Definition of Aurora Borealis


The name 'Aurora Borealis' is Latin and aptly describes the phenomenon that is the Aurora Borealis! A basic definition of Aurora Borealis is luminous arches or streams of light which appear in the in Northern regions of the earth. The Latin words 'Aurora Borealis' are roughly translated as ' Northern Lights' - hence the alternative name! Aurora pertains to the lights ( the red dawn ) and Borealis pertains to the North. The term Aurora Borealis was named by the Italian scientist Galileo Galilei (1564-1642). It is interesting to note that 'Aurora' was the name given to the Roman goddess of dawn.
 
The Legends and Myths surrounding Aurora Borealis



Long ago the appearance of the Aurora Borealis, or the Northern Lights caused a range of emotions in the people who witnessed then - alarm, fear, wonder, dread and excitement to name but a few! People did not understand what caused these amazing spectacles of lights in the sky. The phenomena of the Northern Lights were explained by different stories - the legend and myth of bygone days:






The lights were God or Goddesses appearing to mortals






The lights were spirits or souls dancing in the sky






The red colour was associated with legend or myths relating to blood - murder, death, armies, wars and suicide






The Cause of Aurora Borealis


The Aurora Borealis, or Northern Lights, is caused when material thrown off the surface of the sun collides with the atmosphere of the Earth. The emission of light from atoms is excited by electrons accelerated along the planet's magnetic field lines






The Sun and the Aurora Borealis - Additional Information about the Cause of the Aurora Borealis


The sun emits high energy ion particles. A cloud consisting of ion particles is called a plasma - also known as the solar wind. The ion plasma cloud, the solar wind, interacts with the edge of the earth's magnetic field and some of the particles are trapped by it. These particles are drawn magnetically down into the ionosphere, above the earth's surface. The particles collide with the gases in the ionosphere and produce the colors and the phenomenon called the Aurora Borealis - the Northern Lights.






Definition of Terms!


Various terms are used to explain the Aurora Borealis. A fast reminder of the definitions are helpful and a definition of each associated term follows:






Ionosphere - A region of the earth's atmosphere where ionization caused by incoming solar radiation affects the transmission of radio waves. It extends from a height of 43 miles (70 kilometers) to 250 miles (400 kilometers) above the surface






Ionization - to convert wholly or partly into ions






Ion - An atom or a group of atoms that has acquired a net electric charge






Solar Wind - A stream of high-speed, ionized particles ejected primarily from the sun's corona






Plasma - An electrically neutral, highly ionized gas composed of ions, electrons, and neutral particles






Radiation - Energy radiated or transmitted as rays, waves, in the form of particles






Atmosphere - The gaseous mass a celestial body, especially the one surrounding the earth, and retained by the gravitational field






The Colors of Aurora Borealis


The array of colours in the Aurora Borealis consist of red, blue, violet, and green. Red is the dominant color.






Aurora Borealis Forecast


The appearance of the Aurora Borealis can be forecast by following events on the sun in relation to the speed of the gaseous matter being thrown off its surface. Various types of forecasts and predictions regarding the appearance of the Aurora Borealis, the Northern Lights, are published on several websites on the Internet. The best months to view the phenomena are between October and March. The NASA Space Weather Bureau www.spaceweather.com provides a forecast of viewing the Aurora Borealis, the Northern Lights






Location to view Aurora Borealis


Locations in the Northern hemisphere including Scandinavia, Canada, Northern America, Northern Europe and Siberia. Auroras occur around the magnetic poles in both the Northern and Southern hemispheres.










Fast Facts & Info about Aurora Borealis, also known as the Northern Lights






Aurora Borealis - luminous arches or streams of light






The Aurora Borealis appears in the Northern hemisphere






'Aurora' was the name given to the Roman goddess of dawn!






The Aurora Borealis are caused by the emission of light from atoms excited by electrons accelerated along the planet's magnetic field lines






Aurora Borealis can effect Earth's communications


















Interesting information about the Aurora Borealis - the Northern Lights


The Aurora Borealis






The solar wind can cause interference with radio, television and satellite communications






The size of Solar Flares are events classified as follows:






C-class events - Small solar flares are described as c-class events and have no effect on communications






M-class events - Medium sized solar flares are described as m-class events and can disrupt the Earth's radio communications






X-class events - Large, or extreme, sized solar flares are described as x-class events and can disrupt the Earth's radio communications






The Aurora Borealis does not effect Airplanes as they fly at altitudes well below the Aurora Borealis






The Aurora Borealis is not effected by changes in the temperature of the Earth

The Great Wall Myth

The Great Wall Myth

the great wall of china 1 The Great Wall Of China   World Cultural Heritage





It is common mistake to say that The Great wall of China is visible from outer space. It is too thin to be noticed from such a great distance. There are no man made structures that are visible from space or moon. Man made objects start to disappear after 300 miles up. From that distance you can barely see the outline of the Great China Wall. If we consider that distance from Earth to Moon is around 384,403 kilometers/238,857 miles then we can draw reasonable conclusion that it would be impossible to see any man-made structures from such a distance. Astronaut Alan Bean said: "The only thing you can see from the moon is a beautiful sphere, mostly white (clouds), some blue (ocean), patches of yellow (deserts), and every once in a while some green vegetation. No man-made object is visible on this scale. In fact, when first leaving earth's orbit and only a few thousand miles away, no man-made object is visible at that point either."

Ancient India ..An advanced civilisation

Ancient India Facts



India is a country that will mesmerize you with its intriguing history and fascinating past. Though life has become very complex in modern times, the interesting facts of India continue to awe people all over the world. The country is no ordinary country. In fact, it had the components of a prosperous nation since ancient times only. The rich history of India is full of such interesting facts that one is bound to sit and analyze this fascinating country's history with much enthusiasm. For an amazing collection of facts on ancient India, scroll down.

Indians established Harappan culture in Indus Valley Civilization, at a time when many cultures comprised of nomadic forest dwellers over 5000 years ago.


The game of chess was invented in India.


The birth of Algebra, Trigonometry and Calculus happened in India.


The Decimal and Place Value system originated and developed in India.


In the 13th century, a poet saint named Gyandev introduced the game of Snakes and Ladders. Known as Mokshapat during those times, the game had a significant meaning. The snakes stood for vices, while the ladders represented good virtues. The essence of the game was that the ladders or good virtues take people to heaven while snakes or vices take people to a cycle of re-births.


In 700 BC, the world's first university was established in India, in Takshila. It was one of the biggest achievements in the field of education, as more than 10,500 students came from all over the world to receive education in over 60 different subjects. The University of Nalanda was another milestone that was achieved in the field of education in 4th century BC.


The earliest school of medicine known to mankind was Ayurveda and it originated in India. It was consolidated 2500 years ago by Charaka, the Father of Medicine.


As many as 6000 years back, the art of navigation was developed in the River Indus, which was known as Sindh then. In fact, the word 'navigation' is a derivation of the Sanskrit word, 'Navgatih'.


The correct time taken by the earth to revolve around the sun was calculated by the famous astronomer Bhaskaracharya. His calculation showed that the earth takes around 365.258756484 days to go around the sun once.


In the 6th century, the famous Indian Budhayana mathematician calculated the value of "Pi" and also explained the concept of Pythagoras Theorem.


In the 11th century, Quadratic Equations were introduced by Sridharacharya. Indians used numbers that were way too big than European numbers. While the latter limited themselves to 106, the Indians went a step ahead and used numbers as big as 1053.


Surgery existed in India even 2600 years ago, when Sushruta, known as the Father of Surgery, conducted many complex surgeries. The valuable ancient scriptures have detailed information on Cataract, Artificial Limbs, Cesareans, Fractures, Urinary Stone Surgery, Plastic Surgery and Brain Surgeries.


Anesthesia was used in ancient India and one finds detailed knowledge of the human anatomy and its functions.


Two major religions, Buddhism and Jainism were established in India in 500 and 600 BC.


The oldest city in the world that is inhabited even today is Varanasi or Benaras.


The art of Yoga that is now popular worldwide originated in India only and was performed by highly revered sages, in the ancient times.










How does an MRI work?


How Does an MRI Work



Invention of MRI or magnetic resonance imaging was a revolution in medical diagnosis. This technique of imaging used in diagnosis of various ailments is based on the principles of nuclear magnetic resonance (NMR). It may all sound complicated, but with a little bit of interest, you will realize how an MRI machine generates images of our body.






MRI or magnetic resonance imaging, is a medical imaging technique, which facilitates detailed visualization of the internal structure of our body. It also helps in assessing some functions of the body to a certain extent. The technology, which was introduced in the last quarter of the 20th century, has undergone a dramatic change and gained immense popularity in the field of medicine today. The huge machine referred to as an MRI scanner is an object of fascination for many individuals, who are often left wondering how it works.






The Components of an MRI Machine






Before we move on to the working mechanism of MRI (Magnetic Resonance Imaging), let's take a brief look at the various components of the MRI scanner. The major components of an MRI machine include the primary magnet and the gradient magnets. The primary magnet, made from an electrical coil with power running through it, develops a magnetic field of around 1.5 to 3 Tesla. The gradient magnets, which are much smaller than the primary magnet, help in altering the magnetic field precisely. Other than these, the MRI scanner also includes the horizontal tube, wherein the person is made to lie for examination, and last, but the most important - the computer software and hardware components, which help in setting the parameters prior to the examination, and collecting the data in the form of multiple images.






How Does an MRI Scanner Work?






The MRI scanner is a giant cube, with a horizontal tube attached to it. The patient to be examined is made to lie on his back on this horizontal tube, and then, he is slowly slid into the machine. Whether the entire body of the individual will be sent in or just half of it, depends on which part of the body is to be examined. In case of brain MRI scan, sliding the upper torso of the patient inside the scanner would be enough for the diagnosis. As soon as the body part to be scanned reaches at the isocenter of the magnetic field, the scan begins.






How Does an MRI Generate Images of the Body?






A large part of the human body is composed of water molecules, each of which contains two hydrogen nuclei (or protons). When the patient is sent inside the scanner, the 'magnetic moments' of the protons present in the body align with the direction of the magnetic field. A radio frequency electromagnetic field is turned on for a few seconds, which makes the protons change their alignment relative to the field. As soon as the electromagnetic field is turned off, the protons return to their original alignment. The alterations in the alignment creates a signal which is detected by the scanner. The strength of the magnetic field determines the frequency at which the protons resonate.






Additional magnetic fields are created using the gradient magnets to determine the position of the protons, and the energy released by them. The damaged tissues can be detected as they take time in returning to the state of equilibrium. The parameters are set using the computer and contrast is created between different types of tissues. MRI with contrast is carried out by injecting contrast agents in the body, in order to enhance the appearance of the blood vessels, and to detect tumors and inflammation in the body. The computer takes a note of protons and the energy released by them to generate the image of the body part being examined.






Although MRI can be used to image any part of the body, it is most often used in neurological examinations, checking for tumors, abnormalities in blood vessels etc. MRI scan cost depends on which part of the body is being examined. A safe procedure owing to the exclusion of ionizing radiation, MRI has gained wide popularity in the medical field, across the world.

THE Girl who Excelled in EXCEL



Rebecca Rickwood (15) from Stilton, and attends Sawtry College, recently won a Microsoft Excel world championship in San Diego, and is the best in the world in her category. She also won $5000 USD as part of her prNext year, the 2012 Worldwide Competition on Microsoft Office will be held in Las Vegas, Nevada, USA







Teenage computer whizz Rebecca Rickwood showed she can excel in Excel after winning a worldwide championship.


Talented Rebecca, of Caldecote Road, in Stilton, near Peterborough, has taken home the title of World Champion in Microsoft Excel from the competition in San Diego, in the USA.


To scoop the crown, the 15-year-old beat more than 228,000 students from 57 countries around the globe in a hard fought contest of skill, determination and speed.


A thrilled Rebecca, who is a pupil at Sawtry Community College, had travelled across the Atlantic last Saturday and said she was delighted just to take part in the event.


But after knuckling down to take part on Monday, she then found out on Tuesday she had won, before returning home yesterday with the title and $5,000 prize.


She said: “I took the exams and entered the competition but I didn’t think about it.


“I was so shocked to hear that I had won and was going to San Diego for the finals.


“I’m really excited. I really didn’t think I would win. When I was waiting with all the other students to hear the result I was really nervous.


“I heard my name read out in first place and I just couldn’t believe it. I’m ecstatic, I can’t believe I won and now I’m world champion. It’s a day I’ll never forget.”


She travelled to the US with parents Adam and Tracy (both 46) and brother Matthew (13), who are delighted with her win.


Rebecca added: “We had a good time out there. We didn’t get to see much of San Diego itself, but it was still really good.


“My friends and family are all very happy for me.”


Rebecca had earned her right to attend the world finals in May after she achieved the top nationwide score in the Microsoft Office Specialist Excel certification exam.


She sat the exam at college and since then, she has continued to hone her skills by studying at lunch and in the evenings at her school, supported by teacher Pam Kitchen.


She said: “I’m absolutely delighted for Rebecca.


“She really is a wonderful student who is extremely talented but, also, a very modest person.


“What was most impressive was her hard work and dedication during lunchtimes and after school. We told her to go out to San Diego and be herself and are obviously thrilled to have her coming back to us as world champion.”


Kevin Ryan, marketing manager with Prodigy Learning, who are responsible for the competition in the UK, said: “We realised Rebecca was extremely talented and one to watch from her scores in the UK championships in May.


“But the world competition is another level; it’s highly competitive and notoriously difficult to win, particularly for someone so young.


“Rebecca really has done her country proud. I believe she has a very bright future ahead indeed.”


FACTFILE on... Rebecca’s triumph


THIS year was the 10th annual Worldwide Competition on Microsoft Office.


It features the Microsoft Excel 2007 category, won by Rebecca, but also in Microsoft Word 2010, Microsoft Excel 2010, Microsoft Word 2007 and Microsoft PowerPoint 2007.


It aims to show a student’s ability in the programme with Rebecca tested on formulas, formatting, databases and speed in Excel.

A collection of interesting facts regarding inventions.

– that a workman who left the soap mixing machine on too long was responsible for making Ivory Soap? He was so embarrassed by his mistake that he threw the mess in a stream. Imagine his dismay when the evidence of his error floated to the surface! Result: Ivory soap, the soap that floats.







– that the Band-Aid® Bandage was invented by a Johnson & Johnson employee whose wife had cut herself? Earl Dickson’s wife was rather accident prone, so he set out to develop a bandage that she could apply without help. He placed a small piece of gauze in the center of a small piece of surgical tape, and what we know today as the Band-Aid bandage was born!






– that the inventor of the World Wide Web, British-born Tim Berners-Lee, never made money on his invention, which revolutionized the computer world? In 1989 he envisioned a way to link documents on the Internet using “hypertext” so “surfers” could jump from one document to another through highlighted words. Berners-Lee decided not to patent his technology since he feared that, if he did patent it, use of the Web would be too expensive and would therefore not become used worldwide. He therefore passed up a fortune so the world could learn and communicate.






– that Robert Adler has the dubious distinction of being the Father of the Couch Potato? Back in 1955 Adler was employed by what was then Zenith Radio Corp., where he was charged to invent something that would allow viewers to turn down the TV volume without leaving their chairs. After a series of flops (such as a wired contraption that people tripped over), Adler hit on the idea of using sound waves. Thus the Remote Control was born . . . and some viewers haven’t moved since!






– that in 1879 Auguste Bartholdi received a design patent for the Statue of Liberty?






– that Galileo invented the thermometer in 1593?






– that the first ballpoint pen was invented by Hungarian journalist Lasalo Biro and his chemist brother, Georg, in 1938?






– that power steering was invented by independent inventor Francis W. Davis? As chief engineer in the 1920s of the truck division of the Pierce Arrow Motor Car Company, he saw how hard it was to steer heavy vehicles. So that he would be able to keep the profits from his future invention, Davis left his job, rented a small engineering shop in Waltham, Mass., and developed a hydraulic power steering system that led to power steering.






– that it was melting ice cream that inspired the invention of the outboard motor? It was a lovely August day and Ole Evinrude was rowing his boat to his favorite island picnic spot. As he rowed, he watched his ice cream melt and wished he had a faster way to get to the island. At that moment the idea for the outboard motor was born!






– that two musicians were responsible for the invention of color print film? Fascinated by photography, Leopold Godowsky and Leopold Mannes worked together to produce an easy-to-use, practical color film. They worked full time as music teachers and gave concerts while experimenting during their off hours in Mannes’ kitchen. Their success earned them full-time, well-paying jobs at Kodak and their efforts resulted in Kodachrome film, which was introduced in 1935.






– that the telescope was accidentally discovered in 1698 when Dutch eye glass maker Hans Lippershey looked through two lenses – one held in front of the other – and realized that the image was magnified?






– that one person who claimed to be the inventor of the television is Russian emigre Vladimir Zworykin? In 1929 David Sarnoff, founder of RCA, asked Zworykin what it would take to develop TV for commercial use. He said: a year and a half and $100,000. In reality, it took 20 years and $50 million! Before his death in 1982 at the age of 92, Zworykin said of his invention: “The technique is wonderful. It is beyond my expectations. But the programs! I would never let my children even come close to this thing.”






– that the formulas for Cola-Cola and Silly Putty have never been patented? These trade secrets are shared only with selected trustworthy company employees, and while there have been many attempts to duplicate these products, so far, no one has been successful.






– that Benjamin Franklin invented bifocals because he hated wearing two pairs of glasses?






– that several people are credited with the invention of the flush toilet?
