Logan Sapphire
The Logan Sapphire is a sapphire from Sri Lanka. One of the largest blue faceted sapphires in the world, it was owned by Sir Victor Sassoon and then purchased by M. Robert Guggenheim as a gift for his wife, Rebecca Pollard Guggenheim, who donated the sapphire to the Smithsonian Institution in 1960. The sapphire's name is derived from Rebecca's new surname after she later married John A. Logan. It has been on display in the National Gem Collection of the National Museum of Natural History in Washington, D.C., since 1971.

Chromium
Chromium is a chemical element with the symbol Cr and atomic number 24. It is the first element in group 6. It is a steely-grey, lustrous, hard, and brittle transition metal. Chromium metal is valued for its high corrosion resistance and hardness. A major development in steel production was the discovery that steel could be made highly resistant to corrosion and discoloration by adding metallic chromium to form stainless steel. Stainless steel and chrome plating (electroplating with chromium) together comprise 85% of the commercial use. Chromium is also greatly valued as a metal that is able to be highly polished while resisting tarnishing. Polished chromium reflects almost 70% of the visible spectrum, and almost 90% of infrared light. The name of the element is derived from the Greek word χρῶμα, ''chrōma'', meaning color, because many chromium compounds are intensely colored. Industrial production of chromium proceeds from chromite ore (mostly FeCr2O4) to produce ferro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
First Lady Of The United States
The first lady of the United States (FLOTUS) is the title held by the hostess of the White House, usually the wife of the president of the United States, concurrent with the president's term in office. Although the first lady's role has never been codified or officially defined, she figures prominently in the political and social life of the United States. Since the early 20th century, the first lady has been assisted by official staff, now known as the Office of the First Lady and headquartered in the East Wing of the White House. Jill Biden is the current first lady of the United States, as wife of the 46th and current president of the United States, Joe Biden. While the title was not in general use until much later, Martha Washington, the wife of George Washington, the first U.S. president (1789–1797), is considered to be the inaugural first lady of the United States. During her lifetime, she was often referred to as "Lady Washington". Since the 1790s, the role of fir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1939 New York World's Fair
The 1939–40 New York World's Fair was a world's fair held at Flushing Meadows–Corona Park in Queens, New York, United States. It was the second-most expensive American world's fair of all time, exceeded only by St. Louis's Louisiana Purchase Exposition of 1904. Many countries around the world participated in it, and over 44 million people attended its exhibits in two seasons. It was the first exposition to be based on the future, with an opening slogan of "Dawn of a New Day", and it allowed all visitors to take a look at "the world of tomorrow". When World War II began four months into the 1939 World's Fair, many exhibits were affected, especially those on display in the pavilions of countries under Axis occupation. After the close of the fair in 1940, many exhibits were demolished or removed, though some buildings were retained for the 1964–1965 New York World's Fair, held at the same site. Planning In 1935, at the height of the Great Depression, a group of New Yo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maharaja
Mahārāja (; also spelled Maharajah, Maharaj) is a Sanskrit title for a "great ruler", "great king" or " high king". A few ruled states informally called empires, including ruler raja Sri Gupta, founder of the ancient Indian Gupta Empire, and Chandragupta Maurya. 'Title inflation' soon led to most being rather mediocre or even petty in real power, which led to compound titles (among other efforts) being used in an attempt to distinguish some among their ranks. The female equivalent, Maharani (or Maharanee, Mahārājñī, Maharajin), denotes either the wife of a Maharaja (or Maharana etc.) or also, in states where it was customary, a woman ruling without a husband. The widow of a Maharaja is known as a Rajmata, "queen mother". Maharajakumar generally denotes a son of a Maharaja, but more specific titulatures are often used at each court, including Yuvaraja for the heir (the crown prince). The form "Maharaj" (without "-a") indicates a separation of noble and religious office ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sassoon Family
The Sassoon family, known as "Rothschilds of the East" due to the immense wealth they accumulated in finance and trade, are a family of Baghdadi Jewish descent. Originally based in Baghdad, Iraq, they later moved to Bombay, India, and then emigrated to China, England, and other countries. From the 18th century, the Sassoons were one of the wealthiest families in the world, with a corporate empire spanning the entire continent of Asia.''Siegfried Sassoon: A Biography'', Max Egremont, (London 2005) Etymology The name of the family strongly implies a local, Mesopotamian origin. The family name of Sassoon is also commonly shared by many Armenian and Kurdish families and tribes who all originate from the mountainous district of Sason (whence the family and tribal names), west of Lake Van, in upper Mesopotamia in modern Turkey. It is, however, possible that some Spanish Sephardi blood was mixed with the primarily Mesopotamian Jewish Sasoons. Origins Sassoon ben Salih (1750–1830 ...

Ratnapura
Ratnapura (; ) ("City of Gems" in Sinhala and Tamil) is a major city in Sri Lanka. It is the capital city of Sabaragamuwa Province, as well as the Ratnapura District, and is a traditional centre for the Sri Lankan gem trade. It is located on the Kalu Ganga (Black River) in south-central Sri Lanka, some southeast of the country's capital, Colombo. Ratnapura is also spelled as Rathnapura. The name 'Ratnapura' is a Sanskrit word meaning "city of gems", from the Sanskrit words ''pura'' (town) and ''ratna'' (gemstone). Over 2000 years ago, when the first Buddhist monks arrived here from the north eastern provinces of India namely Bodh-Gaya, Varanasi and Pataliputra, they not only brought with them the Buddhist religion, but since their teachings were mainly in Sanskrit and Pali they also influenced the local language. While candy produced from the jaggery palm is traditionally known in this region as ''ratnapura'', it is more likely that the candy was named for the locale rath ...

Natural History Museum - Logan Sapphire (2)
Nature, in the broadest sense, is the physical world or universe. "Nature" can refer to the phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena. The word ''nature'' is borrowed from the Old French ''nature'' and is derived from the Latin word ''natura'', or "essential qualities, innate disposition", and in ancient times, literally meant "birth". In ancient philosophy, ''natura'' is mostly used as the Latin translation of the Greek word ''physis'' (φύσις), which originally related to the intrinsic characteristics of plants, animals, and other features of the world to develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word φύσις by pre-Socr ...
