Scientific knowledge of ancient Indians.

There are thousands new things that people still don’t know yet. People from all over the world think that they contribute their efforts to find origin of everything. So is important knowledge in modern sciencesdiscovered by ancient Indians?  

1. Age of Earth


The age of the Earth is estimated at a little over 4.5 billion years.Working this out was a difficult problem to solve. For most of human history, the basic facts about the planet were unknown. The problem was tackled by Earth scientists in the twentieth century.
Modern estimates are based on radioactive dating methods. The oldest minerals on Earth – small crystals of zircon from the Jack Hills of Western Australia – are at least 4.4 billion years old.
 
In a famous Indian literary work called Manusmriti, the calculation of the age of the Earth is described in two verses praising Brahma's longevity. (Brahma is the god of creation in Hinduism).  Professor Arthur Holmes, a geologist and professor at Durham University, said: "Many ancient sages tried to predict the age of the world. ancient Hindu study of the concepts of time and origin of the earth in the sacred book Manuscript. "

2. Trigonometry and optics

What is Trigonometry?The branch of mathematics dealing with the relations of the sides and angles of triangles and with relevant functions of any angles.
What is optics?It is the branch of physics which involves the behavior and properties of light, including its interactions with matter and the construction of instruments that use or detect it. Optics usually describes the behavior of visible, ultraviolet, and infrared light.
 
Varahamihira, the astronomer, mathematician and astrologer of the fifth century, defined the concepts of refraction and reflex. He also defined the algebraic properties of zeroes as well as negative numbers. The world of debt India has a tremendous amount of knowledge in the field of mathematics and physics right from the very early days.

3. Discover gravity


Gravity is the force by which a planet or other body draws objects toward its center. The force of gravity keeps all of the planets in orbit around the sun.What else does gravity do?
Why do you land on the ground when you jump up instead of floating off into space? Why do things fall down when you throw them or drop them? The answer is gravity: an invisible force that pulls objects toward each other. Earth's gravity is what keeps you on the ground and what makes things fall.
 
The legendary Vedas of India are over 5,000 years old. And in this ancient business there are verses that suggest that gravity links the universe together and that the Sun is the center of the universe. The Vedas existed for thousands of years as Newton and Copernicus as well as their discoveries came into being.

4. Pythagoras Theorem


A long time ago, a Greek mathematician named Pythagoras discovered an interesting property about right triangles: the sum of the squares of the lengths of each of the triangle’s legs is the same as the square of the length of the triangle’s hypotenuse. This property—which has many applications in science, art, engineering, and architecture—is now called the Pythagorean Theorem.
 
The ancient Indian mathematician Baudhayana wrote a theorem analogous to the Pythagorean theorem in Baudhayana Sulbassutra in 800 BC. This book is one of the oldest books on advanced mathematics left over.  Many historians have suggested that Pythagoras went to many parts of the world and even visited India. Then perhaps he learned the mathematical knowledge from this place, including Pythagoras theorem.  
In a work written by Kim Plofker, professor of mathematics at Brown University, "The mathematical theories of sound as Pythagoras have been applied in the construction of pillars and buildings in India. From ancient times, long before the Greek philosophers knew them. "  

5. Number 0


0 (zero) is both a number and a numerical digit used to represent that number in numerals. As a number, zero means nothing—an absence of other values. It plays a central role in mathematics as the identity element of the integers, real numbers, and many other algebraic structures.
As a digit, zero is used as a placeholder in place value systems. Historically, it was the last digit to come into use. In the English language, zero may also be called nil when a number, o/oh when a numeral, and nought/naught in either context.

 
The Arabic numerals and decimal systems are all native to India. After a long time in secrecy, they were popularized by the Arabs and gradually spread to the west. Aryabhata is the ancient mathematician who is said to have discovered the number zero and the decimal system. In addition, he created the exponentiation and exponentiation 3.

6. High quality steel


Stainless steels are notable for their corrosion resistance, which increases with increasing chromium content. Molybdenum additions increase corrosionresistance in reducing acids and against pitting attack in chloride solutions.
Thus, there are numerous grades of stainless steel with varying chromium and molybdenum contents to suit the environment the alloy must endure. Thus stainless steels are used where both the strength of steel and corrosion resistance are required.
 
In 200 BC, high-quality steel was produced in India through a technique known to Westerners as metallurgy.  William James Durant, a writer, historian, and philosopher wrote in his famous book, The Story of Civilization, states, "By the sixth century, the Hindus It is far superior to Europe in the field of industrial chemicals, and they are the master of distillation, sublimation, the production of metal salts, compounds and alloys. "  

7. The first university in the world


Around 800 AD, a large university in the Takshila area (commonly known as Taxila) was built in the northwestern part of India. At this time, the rest of the world is unaware of the existence of the university concept.  
Joseph Needham, a British scientist and historian, wrote: "When the soldiers of Alexander the Great went to the Taxila region in India in the fourth century BC, they found a university that had hundreds. This is where the three Vedas and the 18 achievements of Hinduism " With 68 subjects were taught at this university.
 
During that time, 10,500 students including those from Babylon, Greece, Syria, China and many more countries students are there. Experienced masters taught the vedas, languages, grammar, philosophy, medicine, surgery, archery, politics, warfare, astronomy, accounts, commerce, documentation, music, dance and other performing arts, futurology, the occult and mystical sciences, complex mathematical calculations.

 

The 14-year-old girl has been eating grease for years, behind the emotional story.

Despite being only 14 years old, a girl name Tran Vu Duong had to squeeze her weight just because she wanted to donate marrow to her father.

Although this month has increased more than 5kg, but 14-year-old girl Tran Vu Duong is hoping she can be fat a little more because of someone she loves very much.  On the afternoon of March 21, Vu Duong quietly lay in bed in the blood transfusion room on the 8th floor, Hiep Hoa Hospital, Chinese Wuhan, watching every fresh drop was removed from the body and entered the division three hours of blood. Tran Kien Quoc, 62, father of Vu Duong is still waiting for blood to be processed, infused.

Since September, Vu Duong’s father has been diagnosed with a syndrome of dysplasia (which is often referred to as lymphoma).

Lymphoma is a cancer of the lymphatic system. It affects a type of white blood cells known as lymphocytes. These help fight disease in the body. They play an important role in the immune system.

This type of cancer starts in the white blood cells, or lymphocytes. As it is present in the bloodstream, it can spread, or metastasize, to different parts of the body.

Here are some key points about lymphoma. More detail is in the body of this article.

  • Lymphoma is a cancer of the lymph nodes and lymphatic system.
  • The two main types are Hodgkin and non-Hodgkin. Non-Hodgkin is the most common.
  • The main symptom is usually an enlargement of lymph nodes that does not go away as it normally would after infection.
  • There is no way to prevent lymphoma, but survival rates after treatment are good.
Since then, underwent 3 chemo, his illness temporarily controlled. But the hospital's doctor urged him to quickly marrow to avoid falling ill, which is the only hope of a man who has entered the other side of his life. Shortly thereafter, the test results from family members showed that his daughter in high school was the only one suitable.

 
Before such results, Mr. Quoc decided not to agree. He gave birth to a child at the age of 48, and that is also the only daughter of the couple. Vu Duong is preparing for the exam to level, so he worried will affect the health as well as education of the daughter. Also his daughter was too small, so he worried the west also wanted to let his daughter help.  
"I'm older, no more afraid, but my daughter's life has just started, she can not be involved."  His wife did not object. They have gotten married for a long time, Mr. Quoc went out to work, earned money for the family. Life became more difficult, he just expected girls can go to college, have a job and livestability. 
By the time his illness worsened, he was unable to go to work. Mr. Quoc still want to hide Vu Duong about his illness. It was not until his daughter found the paperwork, went to the network, knew he had cancer, burst into tears.  Vu Duong insisted on donating marrow to his father, did not change the girl's intentions, he agreed. But a 1-year-old girl weighs only 44kg, but to donate marrow weighing at least 50kg. From there, Vu Duong immediately began to eat more to be able in a short time, reach the prescribed weight.
Each day, Vu Duong ate four meals, each meal must have fat - which she did not once want to eat. In the past, Vu Duong wasafraid of injecting, hate to drink drugs now, every day she must go to the hospital inspection, examination.  
Despite this, Vuong Duong said that her life was donated by her parents, so this is how she responds to their nourishment.  By the time before surgery, weight of Vu Duong reached 49.7 kg, the other criteria are also perfectly suited. In the same three days, she was continuously drawn to the blood, to the father lying on the treatment side. On March 22, the blood transfusion was completed in half.


The story of a 14-year-old girl trying to gain weight to show her father's pulp has been widely spread online so that anyone who reads which is touched andis admired. Before his eyes, Mr. Quoc said, I want to leave the hospital soon to participate in the school's upcoming games of my daughter. "My body is not recovering right now, whether it affects performance or not." "Vu Duong is small, I can not let her lack of a father," he shared.

HBF Wales housing crisis

A new report reveals Wales could face a housing crisis equal to or greater than in England unless urgent action is taken now.

A major new report reveals Wales is set to suffer a housing crisis even more acute than in the rest of the UK.

The report reveals:

· Wales has the oldest housing stock of any Western European nation, much of which is in very poor condition

· rates of housebuilding are so low that today’s new homes will have to last more than 2,000 years before their turn for replacement

· the backlog of unmet housing need has already reached 33,000, whilst four per cent too few homes are being built each year to meet the projected growth in the number of households

· real needs are probably much greater when accounting for areas of low demand resulting from deteriorating or derelict stock

The report 'Building Success: The economic role of new housing in Wales' follows the HBF’s highly influential report of 2002, 'Building a Crisis', which outlined the scale of England’s housing undersupply and compelled the government to put housing at the top of its agenda.

The treasury and the office of the deputy prime minister have now accepted there is a housing crisis in England and the planning system is undergoing major reform to increase housing provision in the south and regenerate communities in the Midlands and the north.

However, rocketing house prices in Wales strongly suggested it was beginning to experience similar problems to the rest of the UK. This report, the first of its kind, confirms those fears. Robert Ashmead, chief executive of the House Builders Federation, said: “All the signs are that, without effective action taken now, Wales is heading for a housing crisis equal to or possibly worse than in the rest of the UK.

“In addition, it faces extra problems of having an exceptionally old housing stock, much of which is in such poor condition that it is close to being unmarketable. This prompts outward migration and the ensuing economic and social decline of once thriving communities.

“We are urging the Welsh Assembly that unless urgent action is taken, the country’s housing crisis will have severe consequences on the future growth and prosperity of the country as a whole.

“The assembly’s aspiration is that within a generation, the standard of living in Wales will match that of the UK as a whole, whilst over the next decade the target is to raise per capita Gross Domestic Product from 80% to 90% of the UK average. Addressing the housing crisis is fundamental to achieving these goals.”

Specific recommendations to the assembly, include:

· to adopt a formal policy position recognising the need for adequate new housing provision

· to formulate a housing strategy to cater for areas of economic growth and to tackle areas of low demand

· to monitor housing completions to ensure regional housing targets are met

· to ensure that a broad mix of house types are provided to meet all forms of demand

The report reveals that more than one-third of Welsh homes are pre-1919 with a further 12% built between the First and Second World Wars. A study in 1998 estimated 8.5% of the Welsh housing stock was classified as “unfit” with a total repair bill of more than Ł1 billion.

Results from the 2001 census show a vacancy rate of 1 in 25 with another 1 in 100 classified as second homes.

Ashmead added: “In numerical terms alone, the undersupply of housing in Wales is not yet as acute as in England but when the age and condition of the stock is taken into account, the crisis is perhaps even more serious than across the border.”

Editors’ Notes

The report 'Building Success: The economic role Of new housing In Wales' will be launched at an all-day conference shared with The Bevan Foundation on Tuesday 20 January 2004 at the Heritage Park Hotel, Trehafod, Pontypridd. Huw Lewis, deputy minister for communities, will be speaking at the conference.

Public Zone

HBF fights hard for the rights of the homebuyer. With housebuilding at its lowest level since the First World War, due to a restrictive planning regime, HBF has led the way in challenging Government to make a its aim of a "decent home for all" a reality.

HBF also works to ensure our members are allowed to build the types of home you, the homebuyer, wants to live in. We are at the forefront of all major housing issues, from improving the design and energy-efficiency of new homes to ensuring new home buyers receive the best service and consumer protection.

The green initiative

HBF has for 15 years organised the greenleaf awards in conjunction with the Daily Mail and key partners. Developments that are awarded are some of the best examples of the role that the landscape plays in successful new housing and clearly show that the developer has taken the time to consider the landscape when building a new home.

To follow on from this the greenleaf standard was launched in May 2002 to enable developers to register their commitment to the greenleaf principles at pre construction stage, so that the site will then go on to be entered for a greenleaf award three years after it has been completed. If you have seen sites with the greenleaf standard flag flying then the site in question is part of the initiative.

The greenleaf standard is managed by both NHMB and Zurich dependent on who the warranty provider is for the site and inspectors go round on a regular basis to ensure that the site is maintaining the standards expected by the greenleaf standard.

Telecommunication

Telecommunication is the technique of transmitting a message, from one point or place to another with the typical additional attribute of being bi-directional. In practice it also recognizes that something may be lost in the process; hence the term 'telecommunication' covers all forms of distance communications, including radio, telegraphy, television, telephony, data communication and computer networking.

The elements of a telecommunication system are a transmitter, a medium (line) and possibly a channel imposed upon the medium (see baseband and broadband as well as multiplexing), and a receiver. The transmitter is a device that transforms or encodes the message into a physical phenomenon; the signal. The transmission medium, by its physical nature, is likely to modify or degrade the signal on its path from the transmitter to the receiver. The receiver has a decoding mechanism capable of recovering the message within certain limits of signal degradation. In some cases, the final "receiver" is the human eye and/or ear (or in some extreme cases other sense organs) and the recovery of the message is done by the brain (see psychoacoustics.)

Telecommunication can be point-to-point, point-to-multipoint or broadcasting, which is a particular form of point-to-multipoint that goes only from the transmitter to the receivers.

The art of the telecommunications engineer is to analyse the physical properties of the line or transmission medium, and the statistical properties of the message in order to design the most effective encoding and decoding mechanisms.

When systems are designed to communicate through human sense organs (mainly vision and hearing), physiological and psychological characteristics of human perception will be taken into account. This has important economic implications and engineers will research what defects may be tolerated in the signal yet not affect the viewing or hearing experience too badly.

Examples of Human (tele)communications

In a simplistic example, take a normal conversation between you and a friend. The message is the sentence your mind decides to communicate to your friend. The transmitter is the language areas in your brain, the motor cortex, your vocal cords, the larynx, and your mouth that produce those sounds called speech. The signal is the sound waves that can be identified as speech. The channel is the air carrying those sound waves, and all the acoustic properties of the space you are in: echoes, ambient noise, reverberation. Between you and your friend (the receiver), may be other technologies that do or do not introduce their own distortions of the original vocal signal (e.g. telephone, HAM radio, IP phone, etc.) The penultimate receiver is your friend's ear, the auditory nerve, the language areas in your friend's brain that will make the difference between your voice and the sound of a car passing by, and decode your speech into, hopefully, the same sentence.

The car passing by is an example of an important property of the channel called noise. Another important aspect of the channel is called the bandwidth, and you would become very aware of the effects of a limited bandwidth if you were now talking to your friend on a telephone or a walkie-talkie.

Other Background

Bell Labs scientist Claude E. Shannon published A Mathematical Theory of Communication in 1948. This landmark publication was to set the mathematical models used to describe communication systems called information theory. Information theory enables us to evaluate the capacity of a communication channelaccording to its bandwidth and signal-to-noise ratio.

At the time of publication, telecommunication systems were predominantly based on analog electronic circuit design. The introduction of mass-produced digital integrated circuits has enabled telecom engineers to take full advantage of information theory. From the demands of telecom circuitry, a whole specialist area of integrated circuit design has emerged called digital signal processing.

Possible imperfections in a communication channel are: shot noise, thermal noise, latency, non-linear channel transfer function, sudden signal drops, bandwidthlimitations, signal reflections (echos). More recent telecommunications systems take advantage of some of these imperfections to actually improve the quality of the channel.

Modern telecommunication systems make extensive use of time synchronization. There is a link between the development of telecommunications and very fine-grained (microsecond) time-keeping technology. Until the recent rise of the use of IP Telephony, most modern, wide-area telecommunications systems were synchronised to atomic clocks, or to secondary clocks synchronised to atomic time.

See modulation for examples of techniques for encoding information into analog signals.

Encyclopedia Entry for statistics

Statistics

Statistics is the science and practice of developing human knowledge through the use of empirical data. It is based soundly on statistical theory which is a branch of applied mathematics. Within statistical theory, randomness and uncertainty are modelled by probability theory. Statistical practice includes the planning, summarizing, and interpreting of uncertain observations. Because the aim of statistics is to produce the "best" information from available data, some authors make statistics a branch of decision theory.

Table of contents

Origin

The word statistics comes from the modern Latin phrase statisticum collegium (lecture about state affairs), from which came the Italian word statista, which means "statesman" or "politician" (compare to status) and the German Statistik, originally designating the analysis of data about the state. It acquired the meaning of the collection and classification of data generally in the early nineteenth century. The collection of data about states and localities continues, largely through national and international statistical services; in particular, censuses provide regular information about the population.

 

Statistical methods

We describe our knowledge (and ignorance) mathematically and attempt to learn more from whatever we can observe. This requires us to

 

  1. plan our observations to control their variability (experiment design),
  2. summarize a collection of observations to feature their commonality by suppressing details (descriptive statistics), and
  3. reach consensus about what the observations tell us about the world we observe (statistical inference).

In some forms of descriptive statistics, notably data mining, the second and third of these steps become so prominent that the first step (planning) appears to become less important. In these disciplines, data often are collected outside the control of the person doing the analysis, and the result of the analysis may be more an operational model than a consensus report about the world.

 

Probability

The probability of an event is often defined as a number between one and zero. In reality however there is virtually nothing that has a probability of 1 or 0. You could say that the sun will certainly rise in the morning, but what if an extremely unlikely event destroys the sun? What if there is a nuclear war and the sky is covered in ash and smoke?

We often round the probability of such things up or down because they are so likely or unlikely to occur, that it's easier to recognise them as a probability of one or zero.

However, this can often lead to misunderstandings and dangerous behaviour, because people are unable to distinguish between, e.g., a probability of 10-4 and a probability of 10-9, despite the very practical difference between them. If you expect to cross the road about 105 or 106 times in your life, then reducing your risk of being run over per road crossing to 10-9 will make you safe for your whole life, while a risk per road crossing of 10-4 will make it very likely that you will have an accident, despite the intuitive feeling that 0.01% is a very small risk.

Use of prior probabilities of 0 (or 1) causes problems in Bayesian statistics, since the posterior distribution is then forced to be 0 (or 1) as well. In other words, the data is not taken into account at all! As Lindley puts it, if a coherent Bayesian attaches a prior probability of zero to the hypothesis that the Moon is made of green cheese, then even whole armies of astronauts coming back bearing green cheese cannot convince him. Lindley advocates never using prior probabilities of 0 or 1. He calls it Cromwell's Rule, from a letter Oliver Cromwell wrote to the synod of the Church of Scotland on August 5th, 1650 in which he said "I beseech you, in the bowels of Christ, consider it possible that you are mistaken."

 

Specialized disciplines

Some sciences use applied statistics so extensively that they have specialized terminology. These disciplines include:

  • Biostatistics
  • Business statistics
  • Economic statistics
  • Engineering statistics
  • Statistical physics
  • Demography
  • Psychological statistics
  • Social statistics (for all the social sciences)
  • Process analysis and Chemometrics (for analysis of data from analytical chemistry and chemical engineering)
  • Reliability engineering

Statistics form a key basis tool in business and manufacturing as well. It is used to understand measurement systems variability, control processes (as in statistical process control or SPC), for summarizing data, and to make data-driven decisions. In these roles it is a key tool, and perhaps the only reliable tool.
