Father of modern chemistry-Lavoisier

Antoine-Laurent de Lavoisier (also Antoine Lavoisier after the French Revolution; French pronunciation: ; 26 August 1743 – 8 May 1794;) was a French nobleman and chemist central to the 18th-century chemical revolution and had a large influence on both the history of chemistry and the history of biology. He is widely considered in popular literature as the "father of modern chemistry".

It is generally accepted that Lavoisier's great accomplishments in chemistry largely stem from his changing the science from a qualitative to a quantitative one. Lavoisier is most noted for his discovery of the role oxygen plays in combustion. He recognized and named oxygen (1778) and hydrogen (1783) and opposed the phlogiston theory. Lavoisier helped construct the metric system, wrote the first extensive list of elements, and helped to reform chemical nomenclature. He predicted the existence of silicon (1787) and was also the first to establish that sulfur was an element (1777) rather than a compound. He discovered that, although matter may change its form or shape, its mass always remains the same.

Lavoisier was a powerful member of a number of aristocratic councils, and an administrator of the Ferme générale. The Ferme générale was one of the most hated components of the Ancien Régime because of the profits it took at the expense of the state, the secrecy of the terms of its contracts, and the violence of its armed agents.All of these political and economic activities enabled him to fund his scientific research. At the height of the French Revolution, he was accused by Jean-Paul Marat of selling adulterated tobacco and of other crimes, and was eventually guillotined a year after Marat's death.

During late 1772 Lavoisier turned his attention to the phenomenon of combustion, the topic on which he was to make his most significant contribution to science. He reported the results of his first experiments on combustion in a note to the Academy on 20 October, in which he reported that when phosphorus burned, it combined with a large quantity of air to produce acid spirit of phosphorus, and that the phosphorus increased in weight on burning. In a second sealed note deposited with the Academy a few weeks later (1 November) Lavoisier extended his observations and conclusions to the burning of sulfur and went on to add that "what is observed in the combustion of sulfur and phosphorus may well take place in the case of all substances that gain in weight by combustion and calcination: and I am persuaded that the increase in weight of metallic calces is due to the same cause.

Do you know about solar wind ?

The solar wind is a stream of charged particles released from the upper atmosphere of the Sun. This plasma consists of mostly electrons, protons and alpha particles with energies usually between 1.5 and 10 keV; embedded in the solar-wind plasma is the interplanetary magnetic field. The solar wind varies in density, temperature and speed over time and over solar longitude. Its particles can escape the Sun's gravity because of their high energy resulting from the high temperature of the corona and magnetic, electrical and electromagnetic phenomena within it.

At a distance of more than a few solar radii from the sun, the solar wind is supersonic and reaches speeds of 250 to 750 kilometers per second.The flow of the solar wind is no longer supersonic at the termination shock. The Voyager 2 spacecraft crossed the shock more than five times between 30 August and 10 December 2007.Voyager 2 crossed the shock about a billion kilometers closer to the Sun than the 13.5 billion kilometer distance where Voyager 1 came upon the termination shock.The spacecraft moved outward through the termination shock into the heliosheath and onward toward the interstellar medium. Other related phenomena include the aurora (northern and southern lights), the plasma tails of comets that always point away from the Sun, and geomagnetic storms that can change the direction of magnetic field lines.

Love message poem in India.

Unnuneeli Sandesam is among the oldest literary works in Malayalamlanguage. It is what is called Sandesa Kavyam (message poem). A Sandesa Kavyam is a message written in poetry, on the lines of the famous Meghadūta of Kalidasa. In the case of this work, it is a message written by a lover to his lady-love staying at a far-off place. The message is therefore written as if it is sent through a messenger. The work was written in the 14th century AD, when transport and communications were very limited in Kerala. The messenger in the poem is, therefore, a carrier pigeon. Apart from the message proper, the poem gives detailed instructions to the messenger pigeon, including the route to be taken and the landmarks en route.

Besides the literary value of the work, it throws light on the geography of Keralaof that period. It, therefore, reads in part like a travelogue too. The journey starts in Thiruvananthapuram the capital of the Venad (Travancore) Kingdom of that day, and ends at Kaduthuruthy a port town then. What amazes readers today is the fact that Kaduthuruthy is no longer a port town, as the sea receded several miles down apparently following a tsunami in 1341. Also, some of the land and water bodies mentioned in the poem are not to be seen now.

The poem is written under the pen-name Amruthanilakshi, and some believe that it was written in 1362 AD. The exact identity of the author remains a mystery, but it is widely believed that one of the members of the Vadakkumkur (Travancore) Royal Family wrote it. An annotated version was published by DC Books.

The mother of thamil nadu,passed away.but live in heart still now.

The mother of thamil nadu passed away.its too heart touching news here. Jayalalithaa Jayaraman (24 February 1948 – 5 December 2016) was an Indian actor and politician who served five terms as the Chief Minister of Tamil Nadu, for over fourteen years between 1991 and 2016. She was a leading actress before her entry into politics and appeared in 140 films from 1961 to 1980 in Tamil, Telugu, Kannada and Hindi industries.She was considered a prolific and versatile actress having appeared in films of different genres and for performing wide variety of characters. She was also known for her dancing skills and was referred to as the queen of Tamil cinema.She was the general secretary of All India Anna Dravida Munnetra Kazhagam (AIADMK) and was popularly referred as Amma, Puratchi Thalaivi, Thanga Gopuram, Thanga Chillai and Thanga Tharagai(Golden Maiden) by her followers. In 2001, an additional letter "a" was appended to the spelling of her name for reasons related to numerology.

As an actress, she frequently worked with another actor-turned-politician, M. G. Ramachandran (MGR). This led to wide speculation that Jayalalitha was introduced to politics by MGR. However, she has denied these claims and stated that she had entered politics by choice. She was a member of the Rajya Sabha, nominated from Tamil Nadu, from 1984 to 1989. Soon after the death of MGR, Jayalalitha proclaimed herself his political heir. She is the second female chief minister of Tamil Nadu after Janaki Ramachandran.

Jayalalithaa became the first incumbent chief minister in India to be disqualified from holding office due to conviction in a disproportionate assets case on 27 September 2014. On 11 May 2015, the Karnataka High Court acquitted Jayalalithaa in the disproportionate assets case, and she resumed office as Chief Minister on 23 May. She was subsequently re-elected by the electorate of the Dr. Radhakrishnan Nagar constituency of North Chennai in a by-election held on 27 June 2015.

She was re-elected as Chief Minister on 19 May 2016 and took the oath as Chief Minister for the sixth time on 23 May 2016.

She died on 5 December 2016 after 75 days of illness and subsequent hospitalisation, where multiple attempts to resuscitate her after she suffered a cardiac arrest failed.

Read about the Kimberly Warm springs.

Kimberley Warm Springs are a geothermal feature and semi-developed visitor site located in the town of Kimberley, north west Tasmania.

The Springs are located within the Kimberley Warm Springs Reserve managed by Parks and Wildlife Service Tasmania. The reserve features a constructed pool, approximately 13 metres by 20 metres and 1.2 metres deep, a sheltered barbecue area, parking and public toilets. Access to the site is from Warm Springs Road off Morrison Street. The site is well signposted within the town.

Water from the springs remains at a constant temperature of 24–-25 degrees Celsius. The water's chemical composition suggests it gains its heat from hotter sub-surface materials. The dissolved solids content is fairly low and contains mainly bicarbonate and calcium ions.

The clearance of shading vegetation has led to excessive algal growth, which is periodically removed as it covers the naturally sandy bottom of the spring.

The spring is the only one of its kind in the north-west of Tasmania. It is home to an endemic snail and an algae (Pithophora spp.) not previously recorded south of Sydney.
