Along with many other texts, Gandhi studied Bhagavad Gita while in South Africa. This Hindu scripture discusses jnana yoga, bhakti yoga, and karma yoga along with virtues such as non-violence, patience, integrity, lack of hypocrisy, self-restraint and abstinence. Gandhi began experiments with these, and in 1906 at age 37, although married and a father, he vowed to abstain from sexual relations.
The Wright brothers made no flights at all in 1906 and 1907. They spent the time attempting to persuade the U.S. and European governments that they had invented a successful flying machine and were prepared to negotiate a contract to sell such machines. They also experimented with a pontoon and engine setup on the Miami River (Ohio) in hopes of flying from the water. These experiments proved unsuccessful.
In 1906, after the abolition of the imperial examinations, the Qing government established many new schools and encouraged students to study abroad. Many young people attended the new schools or went abroad to study in places like Japan.
The statue rapidly became a landmark. Originally, it was a dull copper color, but shortly after 1900 a green patina, also called verdigris, caused by the oxidation of the copper skin, began to spread. As early as 1902 it was mentioned in the press; by 1906 it had entirely covered the statue. Believing that the patina was evidence of corrosion, Congress authorized US$62,800 (equivalent to $1,787,000 in 2019) for various repairs, and to paint the statue both inside and out. There was a considerable public protest against the proposed exterior painting. The Army Corps of Engineers studied the patina for any ill effects to the statue and concluded that it protected the skin, "softened the outlines of the Statue, and made it beautiful." The statue was painted only on the inside. The Corps of Engineers also installed an elevator to take visitors from the base to the top of the pedestal.
Wars and other upheavals in Europe prompted large-scale emigration to the United States in the late 19th and early 20th century; many entered through New York and saw the statue not as a symbol of enlightenment, as Bartholdi had intended, but as a sign of welcome to their new home. The association with immigration only became stronger when an immigrant processing station was opened on nearby Ellis Island. This view was consistent with Lazarus's vision in her sonnet—she described the statue as "Mother of Exiles"—but her work had become obscure. In 1903, the sonnet was engraved on a plaque that was affixed to the base of the statue.
In 1906, William D. Coolidge developed a method of making "ductile tungsten" from sintered tungsten which could be made into filaments while working for General Electric Company. By 1911 General Electric began selling incandescent light bulbs with ductile tungsten wire.
On January 2, 1906, Carrier was granted U.S. Patent 808,897 for an Apparatus for Treating Air, the world's first spray-type air conditioning equipment. It was designed to humidify or dehumidify air, heating water for the first function and cooling it for the second.
In 1905, Stravinsky was engaged to his cousin Katherine Gavrylivna Nosenko (called "Katya"), whom he had known since early childhood. In spite of the Orthodox Church's opposition to marriage between first cousins, the couple married on 23 January 1906.
In 1906, Louvre restorer Eugène Denizard performed watercolour retouches on areas of the paint layer disturbed by the crack in the panel. Denizard also retouched the edges of the picture with varnish, to mask areas that had been covered initially by an older frame.
On 19 April 1906, Pierre Curie was killed in a road accident. Walking across the Rue Dauphine in heavy rain, he was struck by a horse-drawn vehicle and fell under its wheels, causing his skull to fracture. Curie was devastated by her husband's death.
The Russian Constitution of 1906, Created 6 May [O.S. 23 April] 1906, also known as the Fundamental Laws, set up a multiparty system and a limited constitutional monarchy. The revolutionaries were quelled and satisfied with the reforms, but it was not enough to prevent the 1917 revolution that would later topple the Tsar's regime.
On 13 May 1906 the physics department of the University of Paris decided to retain the chair that had been created for her late husband and to offer it to Marie. She accepted it, hoping to create a world-class laboratory as a tribute to her husband Pierre. She was the first woman to become a professor at the University of Paris.
The Wright brothers wrote their 1903 patent application themselves, but it was rejected. In January 1904 they hired Ohio patent attorney Henry Toulmin, and on May 22, 1906, they were granted U.S. Patent 821393 for "new and useful Improvements in Flying Machines".
In 1906, the Nobel Committee for Chemistry recommended to the Swedish Academy, at which Mendeleev was a member, to award the Nobel Prize in Chemistry for 1906 to Mendeleev for his discovery of the periodic system. The Chemistry Section of the Swedish Academy supported this recommendation. The Academy was then supposed to approve the Committee's choice, as it has done in almost every case. Unexpectedly, at the full meeting of the Academy, some members of the committee pressed for the rejection of Mendeleev, arguing that the periodic system was too old to acknowledge its discovery in 1906.
After Wardenclyffe closed, Tesla continued to write to Morgan; after "the great man" died, Tesla wrote to Morgan's son Jack, trying to get further funding for the project. In 1906, Tesla opened offices at 165 Broadway in Manhattan, trying to raise further funds by developing and marketing his patents.
On his 50th birthday, in 1906, Tesla demonstrated a 200 horsepower (150 kilowatts) 16,000 rpm bladeless turbine. During 1910–1911, at the Waterside Power Station in New York, several of his bladeless turbine engines were tested at 100–5,000 hp.
On 12 August [O.S. 30 July] 1906, Russian artillerymen and military engineers rose in revolt in the fortress of Sveaborg (later called Suomenlinna), Helsinki. The Finnish Red Guards supported the Sveaborg Rebellion with a general strike, but the mutiny was quelled within 60 hours by loyal troops and ships of the Baltic Fleet.
President Teddy Roosevelt dishonorably discharged 167 black soldiers because they were accused of crimes as a result of the Brownsville Affair. Many of the discharged soldiers had served for 20 years and were near retirement.
In 1906, the Transvaal government promulgated a new Act compelling registration of the colony's Indian and Chinese populations. At a mass protest meeting held in Johannesburg on 11 September that year, Gandhi urged Indians to defy the new law and to suffer the punishments for doing so.
In September, riots broke out in Atlanta, precipitated by unfounded allegations of black men assaulting white women. This was a catalyst for racial tensions based on a job shortage and employers playing black workers against white workers. Ten thousand whites rampaged through Atlanta, beating every black person they could find, resulting in over 25 deaths.
In the aftermath of the 1906 violence, Du Bois urged blacks to withdraw their support from the Republican Party, because Republicans Roosevelt and William Howard Taft did not sufficiently support blacks. Most African Americans had been loyal to the Republican Party since the time of Abraham Lincoln.
However, Dorgan's earliest usage of hot dog was not in reference to a baseball game at the Polo Grounds, but to a bicycle race at Madison Square Garden, in The New York Evening Journal December 12, 1906, by which time the term hot dog in reference to sausage was already in use. In addition, no copy of the apocryphal cartoon has ever been found.
