26 September - Manne Siegbahn death annivesary

 

Manne Siegbahn, born on 03 December  1886, and passing away on 26 September 1978, was a distinguished Swedish physicist renowned for his pioneering work in the field of X-ray spectroscopy. He made significant contributions to our understanding of the atomic and electronic structure of matter, which had far-reaching implications for various scientific disciplines, including chemistry and physics.

Siegbahn's most notable achievement was the development of X-ray spectroscopy techniques, particularly X-ray emission spectroscopy and X-ray absorption spectroscopy. He refined these methods to investigate the energy levels and electron configurations of atoms and molecules, which provided valuable insights into the behavior of matter at the atomic scale.

In recognition of his groundbreaking contributions to the field, Manne Siegbahn was awarded the Nobel Prize in Physics in 1924. His work laid the foundation for further research in X-ray spectroscopy and the development of synchrotron radiation sources, which have become crucial tools in numerous scientific and industrial applications.

Manne Siegbahn's legacy endures through his significant impact on the study of atomic and molecular structures, and his work continues to be foundational in the realm of modern physics and materials science.

26 Spetember - World Cassowary Day

 

World Cassowary Day is celebrated annually on September 26 to raise awareness about the endangered cassowary, a large flightless bird native to the tropical rainforests of New Guinea, nearby islands, and northern Australia. The day highlights the importance of protecting this unique species and its habitat, as cassowaries play a vital role in their ecosystems by dispersing seeds from the fruits they eat.

The Southern Cassowary, in particular, is considered a keystone species due to its ecological role. Unfortunately, the cassowary population is under threat from habitat destruction, vehicle collisions, and human activity.

Events and activities on World Cassowary Day focus on educating people about conservation efforts, protecting cassowary habitats, and encouraging responsible interaction with wildlife.

26 September - Petrov Day

 

Petrov Day is observed annually on September 26 to commemorate a critical moment in history when a single individual, Soviet Lieutenant Colonel Stanislav Petrov, prevented a potential nuclear war between the United States and the Soviet Union during the Cold War.

On September 26, 1983, amidst heightened tensions between the superpowers, Soviet early-warning systems detected what appeared to be a missile launch from the United States. The system indicated that five U.S. missiles were headed towards the Soviet Union. Protocol at the time would have required Petrov, who was the duty officer at the command center, to report the alarm up the chain of command, potentially triggering a retaliatory nuclear strike.

However, Petrov made a calm and critical decision: he chose to dismiss the alarm as a false report, reasoning that a real attack would likely involve hundreds of missiles, not just five. His intuition and refusal to follow protocol averted what could have been a catastrophic nuclear conflict. It was later confirmed that the alert was a malfunction in the Soviet satellite system, and Petrov's judgment had saved the world from disaster.

Petrov Day is celebrated as a reminder of the importance of peace, rational thinking, and the weight of individual responsibility in preventing global crises. It highlights how a single person’s decision, guided by reason and caution, can have profound effects on humanity’s survival.

26 September - Revolution Day in Yemen

 

Revolution Day in Yemen, celebrated on 26 September commemorates the Yemeni Revolution of 1962, which marked the end of the centuries-old monarchy and the establishment of the Yemen Arab Republic (North Yemen). The revolution began when army officers, inspired by Arab nationalist movements and supported by Egypt's President Gamal Abdel Nasser, overthrew the rule of Imam Muhammad al-Badr, the last ruler of the Mutawakkilite Kingdom of Yemen.

On 26 September 1962, revolutionary forces, led by Abdullah al-Sallal, stormed the royal palace in Sana'a and declared the establishment of a republican government. This event set off a civil war between republican forces, supported by Egypt, and royalist factions, backed by Saudi Arabia. The conflict, which lasted until 1970, ended with the eventual victory of the republicans and the consolidation of the Yemen Arab Republic.

Revolution Day is a significant public holiday in Yemen, symbolizing the country's struggle for self-determination and modernization. It is marked with patriotic events, parades, and speeches, reflecting on the sacrifices made for independence and the ongoing challenges faced by the nation.

26 September - Sir Francis Drake completes his circumnavigation of the globe.

 

On 26 September 1580, Sir Francis Drake completed his historic circumnavigation of the globe, becoming the first Englishman to do so. His voyage, which began on 13 December 1577, was commissioned by Queen Elizabeth I, partly as an exploration mission and partly as a secretive campaign against Spanish holdings and ships.

Drake's expedition faced numerous challenges, including navigating treacherous waters, conflicts with the Spanish, and the loss of ships. However, it was also immensely profitable, as Drake raided Spanish settlements and captured vast amounts of treasure along the way, especially from the Spanish galleon "Cacafuego" off the coast of Peru.

After navigating the Pacific, Indian, and Atlantic Oceans, Drake and his ship, the "Golden Hind," returned to Plymouth, England, on 26 September , 1580, with a wealth of treasure and valuable knowledge about the world’s oceans and trade routes. Upon his return, he was knighted by Queen Elizabeth I aboard the "Golden Hind" in 1581, cementing his status as a national hero. His successful circumnavigation contributed to England's growing naval power and exploration ambitions during the Elizabethan era.

26 September - Sir Charles Vyner Brooke birth anniversary

 

Sir Charles Vyner Brooke was the third and last White Rajah of Sarawak, a region on the island of Borneo in Southeast Asia. He was born on 26 September 1874, and died on 09 May 1963.

The White Rajahs were members of the Brooke family who ruled Sarawak as independent sovereigns from 1841 to 1946. Charles Vyner Brooke succeeded his uncle, Sir Charles Johnson Brooke, as the Rajah of Sarawak in 1917. However, during his reign, Sarawak faced economic and political challenges.

After the Japanese occupation during World War II, Charles Vyner Brooke ceded Sarawak to the British Crown in 1946. This marked the end of the Brooke dynasty's rule in Sarawak. After the cession, Sarawak became a British Crown Colony until Malaysia gained independence in 1963.

26 September - T. S. Eliot birth anniversary

T. S. Eliot, whose full name is Thomas Stearns Eliot, was a prominent American-English poet, playwright, essayist, and literary critic. He was born on September 26, 1888, in St. Louis, Missouri, and passed away on January 4, 1965, in London, England. T. S. Eliot is regarded as one of the most influential poets of the 20th century and a key figure in modernist literature.

Eliot's poetic works are known for their complex and often highly allusive style. He is perhaps best known for his long poem "The Waste Land," published in 1922. "The Waste Land" is often considered a landmark of modernist poetry and is known for its fragmented narrative, rich cultural references, and exploration of themes of disillusionment and the decline of Western civilization.

Another of Eliot's notable works is "The Love Song of J. Alfred Prufrock," which was published in 1915 and is often seen as a precursor to "The Waste Land." This poem explores the inner thoughts and anxieties of its titular character, reflecting themes of alienation and the search for meaning in the modern world.

In addition to his poetry, T. S. Eliot was a significant essayist and literary critic. He wrote several influential essays on poetry and literary theory, including "Tradition and the Individual Talent" and "The Metaphysical Poets," which had a profound impact on the way literature was analyzed and understood.

T. S. Eliot's contributions to literature earned him numerous accolades, including the Nobel Prize in Literature in 1948. His works continue to be studied and celebrated for their intellectual depth, innovative style, and profound exploration of the human condition in the modern world.
