He proposed a fresh theory of alkalis which later was accepted in chemical practices.

" Karpov acknowledged that his understanding of chess theory was very confused at that time, and wrote later that the homework which Botvinnik assigned greatly helped him, since it required that he consult chess books and work diligently.

A year later, in 1931, Dirac modified his theory and postulated the positron, a new particle of the same mass as the electron.

He established the consistent use of the chemical balance, used oxygen to overthrow the phlogiston theory, and developed a new system of chemical nomenclature which held that oxygen was an essential constituent of all acids ( which later turned out to be erroneous ).

A fourth theory is that the longer Western text came first, but that later, some other redact or abbreviated some of the material, resulting in the shorter Alexandrian text.

According to this new theory, the shorter Alexandrian text is closer to the original, and the longer Western text is the result of later insertion of additional material into the text.

Jay comments that this is sometimes seen as an early reference to the idea of the transmission of grace through the apostolic succession which in later centuries was understood as being specifically transmitted through the laying on of hands by a bishop within the apostolic succession ( the " pipeline theory ").

A few years later, Ann Watts published a book in which she argued against the imperfect application of traditional, Homeric, oral-formulaic theory to Anglo-Saxon poetry.

In chaos theory, the butterfly effect is the sensitive dependence on initial conditions, where a small change at one place in a deterministic nonlinear system can result in large differences to a later state.

Pascal was an important mathematician, helping create two major new areas of research: he wrote a significant treatise on the subject of projective geometry at the age of sixteen, and later corresponded with Pierre de Fermat on probability theory, strongly influencing the development of modern economics and social science.

In the 1920s and 1930s almost every major cosmologist preferred an eternal steady state Universe, and several complained that the beginning of time implied by the Big Bang imported religious concepts into physics ; this objection was later repeated by supporters of the steady state theory.

Over the last half of the 20th century, historical and archaeological research has increasingly supported the theory that the remnants of the Celtic Boii were absorbed into the Roman Empire and later intermingled with other Germanic peoples who chose to stay ( or were stationed by the Romans ) in the area.

According to this theory, depressed people acquire a negative schema of the world in childhood and adolescence as an effect of stressful life events, and the negative schema is activated later in life when the person encounters similar situations.

The subsequent development of category theory was powered first by the computational needs of homological algebra, and later by the axiomatic needs of algebraic geometry, the field most resistant to being grounded in either axiomatic set theory or the Russell-Whitehead view of united foundations.

General category theory, an extension of universal algebra having many new features allowing for semantic flexibility and higher-order logic, came later ; it is now applied throughout mathematics.

Traditional Chinese medicine ( TCM ) is based on Yinyangism ( i. e., the combination of Five Phases theory with Yin-yang theory ), which was later absorbed by Daoism.

However, the later edition in 1959 failed to adequately address the problems that appeared to be better understood by molecular orbital theory.

Although Wegener's theory was formed independently and was more complete than those of his predecessors, Wegener later credited a number of past authors with similar ideas:

The function of the nucleus as carrier of genetic information became clear only later, after mitosis was discovered and the Mendelian rules were rediscovered at the beginning of the 20th century ; the chromosome theory of heredity was therefore developed.

Based on this idea and the atomic theory of John Dalton, Joseph Proust had developed the law of definite proportions, which later resulted in the concepts of stoichiometry and chemical equations.

" Han independence " was therefore scrapped in favor of the Five Races Under One Union principle, which later developed into the theory of Zhonghua minzu.

Billions of years later, all evidence of that fact has been erased or denied and it is considered just a silly theory.

This theory, which was repeated by later antiquaries, is bolstered, or may have derived from, Cadbury's proximity to the River Cam and towns Queen Camel and West Camel, and remained popular enough to help inspire a large-scale archaeological dig in the 20th century.

But a moment later he brought his horse forward into the light, and Wilson had a good look at him.

Essentially, the question presented for decision in the present Daytime Skywave proceeding is whether our decision ( in 1938-1939 ) to assign stations on the basis of daytime conditions from sunrise to sunset, is sound as a basis for AM allocations, or whether, in the light of later developments and new understanding, skywave transmission is of such significance during the hours immediately before sunset and after sunrise that this condition should be taken into account, and some stations required to afford protection to other stations during these hours.

The program was named after the Greek god of light, music, and the sun by NASA manager Abe Silverstein, who later said that " I was naming the spacecraft like I'd name my baby.

As soon as Schliemann came on the Mycenae graves three years later, light poured from all sides on the prehistoric period of Greece.

It was discovered in 1725 and later explained by the third Astronomer Royal, James Bradley, who attributed it to the finite speed of light and the motion of Earth in its orbit around the Sun.

In the summer of 1993, Dick Zimmerman, a 44-year-old retired broadcasting executive from Larkspur, California, happened to see the episode in which Butt-head joked, “ Hey, Beavis, let ’ s go over to Stewart ’ s house and light firecracker in his cat ’ s butt .” Five days later, a cat was found killed by a firecracker in nearby Santa Cruz.

These were later followed by two Alouette III SA. 316 B helicopters, used mostly for liaison purposes, one twin-engined Aero Commander 500 light utility aircraft, two Hawker-Siddeley HS. 748-2A twin turboprop transport aircraft, and two Nord 262 twin turboprop transport aircraft.

Early piano music was light in texture, often with Alberti bass accompaniment, but it later became richer, more sonorous and more powerful.

Together they shared new approaches to art, painting the effects of light en plein air with broken color and rapid brushstrokes, in what later came to be known as Impressionism.

Ironically, the rise of infantry in the early 16th century coincided with the " golden age " of heavy cavalry ; a French or Spanish army at the beginning of the century could have up to half its numbers made up of various kinds of light and heavy cavalry, whereas in earlier medieval and later 17th century armies the proportion of cavalry was seldom more than a quarter.

Louis de Broglie later ( 1924 ) showed in his doctoral dissertation that electrons are in fact much like photons in the respect that they act both as waves and as particles in a dual manner as Einstein had shown earlier for light.

Only a year later, at the age of 39, Doppler gave a lecture to the Royal Bohemian Society of Sciences and subsequently published his most notable work, " Über das farbige Licht der Doppelsterne und einiger anderer Gestirne des Himmels " ( On the coloured light of the binary stars and some other stars of the heavens ).

Although Van Gogh never boarded with him, Pissarro did explain to him the various ways of finding and expressing light and color, ideas which he later used in his paintings, notes Lucien.

Following the murder of Stephen Lawrence, the Macpherson Report recommended that the double jeopardy rule should be abrogated in murder cases, and that it should be possible to subject an acquitted murder suspect to a second trial if " fresh and viable " new evidence later came to light.

However, the later discovery of the photoelectric effect demonstrated that under different circumstances, light can behave as if it is composed of discrete particles.

Later, Albert Einstein proposed that the quanta of light might be regarded as real particles, and ( still later ) the particle of light was given the name photon, to correspond with other particles being described around this time, such as the electron and proton.

His theory of the photoelectric effect ( for which he won the Nobel prize for physics ) posited that light could exist in discrete particle-like quantities, which later came to be known as photons.

Several centuries later, in late Dark Age Europe, the term " firearm " was used in Old English to denote the arm in which the match was held that was used to light the touch hole on the hand cannon.

According to the contemporary sources and later speculations, the first line was formed by light cavalry archers ( Battle of Oslava-1116, 1146, 1260, 1278 ).

On 6 October 2010, during the Conservative Party Conference, it was revealed that 22 had been given the provisional ' green light ' to proceed and others may later be accepted with amendments.

Despite his light letter-writing in youth, in later life his correspondence was so voluminous that it has been estimated that he may have written around 30, 000 letters to various correspondents, a figure which places him second only to Voltaire as an epistolarian.

The outgoing light rays start exactly at the edge of the black hole and spend a long time near the horizon, while the infalling matter only reaches the horizon much later.

Cases vary greatly in weight and sturdiness: Italian harpsichords are often of light construction ; heavier construction is found in the later Flemish instruments and those derived from them ( see History of the harpsichord ).

Though the details would be modified in light of his later work, Kepler never relinquished the Platonist polyhedral-spherist cosmology of Mysterium Cosmographicum.
