Giotto mission

100 Giotto was a European unmanned space mission from the European Space Agency planned to flying by and studies Halley's Comet.

Mission
On March 13, 1986, Giotto approached at a 596 kilometer detachment from Halley's nucleus.

The space probe "Giotto" from the European Space Agency was planned to study Halley's Comet. The spaceship was named after the medieval Italian painter Giotto di Bondone. He had observed Halley's Comet in 1301 and was stimulated to depict it as the star of Bethlehem in his painting The Christmas Story.

Originally a United States partner probe was intended that would accompany Giotto, but this fell from side to side due to budget cuts at NASA. There were plans to have watching equipment on-board a Space Shuttle in low-Earth orbit around the time of Giotto's fly-by, but they fell through with the Challenger disaster.

Atomic clock

An atomic clock is a type of clock so as to uses an atomic resonance frequency standard as its counter. Early atomic clocks were masers by means of attached equipment. Today's best atomic frequency standards (or clocks) are based on more advanced physics involving cold atoms and atomic fountains. National standards agencies maintain an accuracy of 10-9 seconds per day, and a precision equal to the frequency of the radio transmitter pumping the maser. The clocks keep up a continuous and stable time scale, International Atomic Time (TAI). For civil time, another time scale is disseminated, Coordinated Universal Time (UTC). UTC is derived from TAI, but coordinated with the passing of day and night based on astronomical observations.

Nectarines

Nectarine tree in full flower The nectarine is a variation of peach that has a fuzzless skin. Though grocers treat fuzzy peaches and nectarines as dissimilar fruits, they belong to the same species. Nectarines have arisen many times from fuzzy peaches, often as bud sports. Nectarines can be white, yellow, clingstone, or freestone. Regular peach trees infrequently produce a few nectarines, and vice versa. Nectarines are more simply damaged than fuzzy peaches. The history of the nectarine is unclear; the first recorded mention is from 1616 in England, but they had probably been grown very much earlier in central Asia.

Places to see in Jaipur

Places to see in Jaipur
Amber Palace The Amber Palace complex overlooking the artificial lake south of the town of Amber is one of the most well-liked tourist sites in the city, famous for its mixture of Hindu and Muslim architecture, and offering elephant rides from the town up to the palace courtyard. Although the structure is today known as Amber Fort, the complex was at first a Palace Complex within the Fort of Amber which is today known as Jaigarh fort.
Jaigarh Fort The Jaigarh Fort on the hills above the Amber Palace complex offers stunning views of the foothills of the Aravalli range, as well as attractions such as vast underground water-storage tanks, a medieval canon foundry and an impressive collection of medieval cannons with the Jaivana which is supposed to be the world's largest cannon on wheels. in the past this was the original Amber Fort, although it became known as Jaigarh from the time of Sawai Jai Singh II onwards.
Jal Mahal is located in Jaipur India, which is the capital of the State of Rajasthan. It is on the way to Sisodia garden. The rajput style "Water Palace" sits in the center of the Man Sarobar lake. The lake is frequently dry in the summer but winter monsoons frequently turn it into a beautiful lake filled with water hyacinths.

Recreation

Recreation is the use of time in a non-profitable way, in many ways also therapeutic refreshment of one's body or mind. While leisure is more likely a type of entertainment or rest, recreation is active for the participant but in a refreshing and diverting manner. As people in the world's richer regions lead increasingly sedentary life styles, the need for recreation has grown. The rise of so called active vacations exemplifies this trend.

Air pollution

Air pollution is a chemical, physical (e.g. particulate matter), or biological agent that modifies the normal characteristics of the atmosphere. Stratospheric ozone depletion due to air pollution has long been known as a threat to human health as well as to the earth's ecosystems.
Worldwide air pollution is in charge for large numbers of deaths and cases of respiratory disease. Enforced air quality standards, like the Clean Air Act in the United States, have reduced the occurrence of some pollutants. While major stationary sources are often identified with air pollution, the greatest source of emissions are in fact mobile sources, principally the automobile. Gases such as carbon dioxide, which contribute to global warming, have newly gained recognition as pollutants.

Magnets

Magnets are materials that creates a magnetic field of their own. Extreme examples of magnets are "hard", or "permanent" magnets (like refrigerator magnets), which remember how they have been magnetized, and "soft", or "impermanent" magnets (like the material of the refrigerator door), which lose their memory of previous magnetizations. "Soft" magnets are often used in electromagnets to enhance (often by factors of hundreds or thousands) the magnetic field of a current-carrying wire that has been wrapped in the region of the magnet; when the current increases, so does the field of the "soft" magnet, which is much larger than the field due to the current. Permanent magnets occur naturally in some rocks, mainly lodestone, but they are now more commonly manufactured.
Materials without a permanent magnetic moment can, in the occurrence of magnetic fields, be attracted (paramagnetic), or repelled (diamagnetic). Liquid oxygen is paramagnetic; graphite is diamagnetic. "Soft" magnets, which are powerfully attracted to magnetic fields, can be thought of as strongly paramagnetic; superconductors, which are strongly repelled by magnetic fields, can be thought of as strongly diamagnetic.
