Dmitri Mendeleev presents the first periodic table to the Russian Chemical Society.
Dmitri Mendeleev first presented his periodic table of elements to the Russian Chemical Society on March 6, 1869, revolutionizing chemical classification.
Mendeleev’s landmark presentation introduced an organized table arranging elements by atomic weight and chemical properties.
He left gaps for undiscovered elements, predicting their existence and characteristics with remarkable accuracy.
The periodic table provided a unifying framework for chemistry, guiding future discoveries and element research.
His work earned international recognition and became an essential tool for scientists worldwide.
The periodic law he formulated remains a cornerstone of modern chemical science and education.

Scottish National Antarctic Expedition: Led by William Speirs Bruce, the Antarctic region of Coats Land was discovered from the Scotia.
The 1904 Scottish National Antarctic Expedition discovered Coats Land, expanding knowledge of Antarctica's geography.
On March 6, 1904, William Speirs Bruce and his crew aboard the Scotia sighted and charted Coats Land on the east side of the Weddell Sea.
This discovery filled significant gaps in existing Antarctic maps and improved understanding of the continent's coastline.
Bruce's scientific team conducted oceanographic, biological, and meteorological observations throughout the voyage.
Despite harsh ice conditions and severe cold, the expedition collected valuable data on marine life and magnetic fields.
The findings contributed to later polar research and established Scotland's legacy in early 20th-century exploration.

The Michelangelo computer virus begins to affect computers.
In 1992, the Michelangelo computer virus activated on affected PCs, threatening data and marking one of the first widespread antivirus scares.
Discovered in the late 1980s, the Michelangelo virus was designed to overwrite hard drive sectors on March 6. When the date arrived in 1992, antivirus firms warned users of potential data loss. Although media hype predicted massive damage, the actual impact was limited by early detection. Still, fears led to a surge in antivirus software sales and stronger computer security awareness. The virus demonstrated the vulnerabilities of personal computers to malware. It prompted improved backup practices and spawned a dedicated industry to combat digital threats. Michelangelo’s legacy persists in discussions of cyber preparedness and virus prevention.
