UNKNOWNS OF LEONARDO DA VINCI

Leonardo da Vinci is best remembered as the painter of the Mona Lisa (1503-1506) and The Last Supper (1495). But he's almost equally famous for his astonishing multiplicity of talents: he dabbled in architecture, sculpture, engineering, geology, hydraulics and the military arts, all with success, and in his spare time doodled parachutes and flying machines that resembled inventions of the 19th and 20th centuries. He made detailed drawings of human anatomy which are still highly regarded today. Leonardo also was quirky enough to write notebook entries in mirror (backwards) script, a trick which kept many of his observations from being widely known until decades after his death.

Birth name- Leonardo di Ser Piero
Born- April 15, 1452(1452-04-15) Vinci, Florence, in present-day Italy
Died- May 2, 1519 (aged 67)Amboise, Indre-et-Loire, in present-day France
Nationality- Tuscan, Italian
Field- Many and diverse fields of arts and sciences
Movement- High Renaissance
Famous works- Mona Lisa, The Last Supper, The Vitruvian Man


It is primarily as a painter that Leonardo was and is renowned. Two of his works, the Mona Lisa and The Last Supper occupy unique positions as the most famous, most reproduced and most parodied portrait and religious painting of all time, their fame approached only by Michelangelo's Creation of Adam.[1] Leonardo's drawing of the Vitruvian Man is also iconic. Perhaps fifteen paintings survive, the small number due to his constant, and frequently disastrous, experimentation with new techniques, and his chronic procrastination.[b] Nevertheless these few works, together with his notebooks, which contain drawings, scientific diagrams, and his thoughts on the nature of painting, comprise a contribution to later generations of artists only rivalled by that of his contemporary, Michelangelo.



As an engineer, Leonardo conceived ideas vastly ahead of his own time, conceptualising a helicopter, a tank, concentrated solar power, a calculator, and the double hull, and outlining a rudimentary theory of plate tectonics. Relatively few of his designs were constructed or even feasible during his lifetime,but some of his smaller inventions such as an automated bobbin winder and a machine for testing the tensile strength of wire entered the world of manufacturing unheralded. As a scientist, he greatly advanced the state of knowledge in the fields of anatomy, civil engineering, optics, and hydrodynamics.
Virgin and Child with St Anne, return None of Leonardo's paintings are signed. Certain works still in existence are cited by Vasari or are referred to in contracts. All notes in this section are drawn from the analysis of opinions of various scholars by Angela Ottino della Chiesa.
Entirely by Leonardo -
The Last Supper (1498)—Convent of Sta. Maria delle Grazie, Milan, Italy
Mona Lisa or La Gioconda (1503–1505/1507)—Louvre, Paris, France
Adoration of the Magi unfinished painting (1481)—Uffizi, Florence, Italy
The Virgin and Child with St. Anne (c. 1510)—Louvre, Paris, France
Virgin of the Rocks, Louvre, Paris, considered by most historians to be the earlier of two versions and to therefore date from 1483–1486.
The Virgin and Child with St. Anne and St. John the Baptist large drawing (c. 1499–1500)—National Gallery, London, UK.
St. Jerome in the Wilderness, (c.1480), Vatican, unfinished painting.

The Baptism of Christ (1472–1475)—Uffizi, by Verrocchio and Leonardo
Leonardo with other hands -
The Baptism of Christ (1472–1475)—Uffizi, Florence, Italy. Cited by Vasari as by Verrocchio, with the angel on the left-hand side by Leonardo.[8] It is generally considered that Leonardo also painted the background landscape and the torso of Christ. One of Leornardo's earliest extant works.[x]
Virgin of the Rocks, National Gallery, London, generally accepted as postdating the version in the Louvre, possibly 1505–1508, with collaboration of de Predis and perhaps others.[y]


Virgin of the Rocks, National Gallery, London, possibly 1505–
1508, demonstrates Leonardo's interest in nature.

Extra credit: Leonardo da Vinci means "Leonardo from the town of Vinci," and thus he is generally referred to in short as "Leonardo" rather than as "da Vinci"... He received a fresh burst of public interest in 2003 with the publication of The Da Vinci Code, the bestselling thriller by author Dan Brown.

CLIMATE SAVERS COMPUTING INITIATIVE

Started by Google and Intel, the Climate Savers Computing Initiative brings together industry, consumers,government, and conservation organizations to significantly increase the energy efficiency of computers and servers. Believe it or not, the average desktop PC wastes over half the power delivered to it! Servers are slightly more efficient but still squander about one-third of the power consumed. This wasted electricity unnecessarily increases the cost to power computers and also increases the emissions of greenhouse gases. Improving the energy efficiency of computers is one of the most cost-effective ways to reduce electricity consumption and the greenhouse gas emissions that contribute to climate change.

Through more efficient design optimized for power consumption alongside speed, capacity and cost, together with use of power-saving technologies, the electricity required to power computers can be significantly reduced while at the same time increasing their computing capabilities. As participants in this program, computer and component manufacturers commit to produce products that meet specified power-efficiency targets, and corporate participants commit to purchase power-efficient computing products. In addition, the Initiative will educate consumers and IT personnel about power management of computers and show individuals how they can reduce the electrical footprint of their computers without any resulting loss of productivity.

Increased deployment of high-efficiency systems combined with education and power management technologies will save money, reduce energy consumption, and reduce greenhouse gas emissions. By 2010, the focused effort of technology providers and committed participants will lead to about a 50% reduction in annual power consumption by computers, and committed participants in the Initiative could collectively save $5.5 billion in energy costs.

(Former Chinese ambassador to USA)

ALL OF THE ABOVE IS JUST THE TIP OF THE ICEBERG, THE LIST COULD BE ENDLESS. BUT,

if we don’t see even a glimpse of that great India in the India that we see today, it clearly means that we are not working up to our potential; and that if we do, we could once again be an ever shining and inspiring country setting a bright path for rest of the world to follow. I hope you enjoyed it and work towards the welfare of INDIA.
