Nowe Ateny: Poland’s Eccentric First Encyclopedia

 The Nowe Ateny (New Athens) , published in 1745 by priest Benedykt Chmielowski , holds a unique place in history as the first Polish encyclopedia .

The Kauri Gum Diggers of New Zealand

 The history of New Zealand is filled with unique industries that shaped its culture and economy. Among them, the story of the kauri gum diggers stands out as one of the most fascinating chapters. For more than a century, from the mid-1800s to the early 1900s, thousands of people worked as gum diggers in the northern regions of New Zealand, extracting resin from the mighty kauri trees. This resin, known as kauri gum , played an important role in local livelihoods, global trade, and even the development of art and industry.

When the tree was injured, it secreted resin to heal itself, which eventually hardened and preserved for thousands of years in the soil or swamps. The gum varied in color from pale g...

Project Diana: Bouncing Radio Waves Off The Moon

In the history of space exploration and communication technology, Project Diana holds a special place. Conducted by the United States Army Signal Corps in 1946, it was the first successful attempt to bounce radio waves off the Moon and receive their echo back on Earth. This groundbreaking experiment not only proved that communication with objects beyond Earth was possible, but it also laid the foundation for radar astronomy and space communications as we know them today. Credit:  Pierre PRESTAT The Birth of Project Diana At the end of World War II, scientists and engineers were eager to apply radar technology to new frontiers. Under the leadership of John H. DeWitt Jr., a team at Fort Monmouth, New Jersey, began working on a bold idea: using radar to detect and reflect signals from the Moon. They named the experiment Project Diana , after the Roman goddess of the Moon. The challenge was immense. Radio signals had to travel nearly 500,000 miles round trip, overcoming atmospheri...
