Fujian Tulou, China
Let"s step into a world of giant earthen homes designed to house a village. These "tulou" structures, built between the 12th and 20th centuries, are the dwellings of the Hakka community in China"s mountainous southeastern Fujian region.

Fibonacci Day
Fibonacci Day
On Fibonacci Day, mathematicians and scientists honor one of their own: Leonardo Bonacci, better known as Fibonacci. The medieval mathematician popularized the Hindu-Arabic numeral system, with its use of zero, decimal points, and 10 numbers instead of the ponderous Roman numeral system. He"s most famous, however, for his sequence of numbers: 0, 1, 1, 2, 3, 5, 8... By adding the first two numbers, you arrive at the third, and adding the previous two numbers, you arrive at the next number, and so on. Disregarding the zero, the first four numbers correspond to today"s date, 11/23.Desktop Version

Ides of March
Ides of March
As Shakespeare wrote in his play "Julius Caesar," "Friends, Romans, countrymen, lend me your ears." Today is the Ides of March, a day steeped in Roman history and tradition. The term "Ides" referred to the midpoint of the month in the Roman calendar, often marking the full moon. It was a time of celebration, with festivals and public gatherings. However, in 44 BCE, the Ides of March became synonymous with political upheaval, betrayal, and an event that would trigger the fall of the Roman Republic. On that fateful day, Julius Caesar, Rome"s powerful dictator, was assassinated by a group of senators. The conspirators, including his close ally Brutus, believed they were saving the Republic from Caesar"s growing authority. Caesar was attacked near the Theater of Pompey, but the tension of that moment echoed through the Roman Forum—the beating heart of Rome"s political and social life.Desktop Version

African bush elephants in Namibia
African bush elephants in Namibia
Desert elephants, found in Namibia and Mali, are African bush elephants that have adapted to the harsh conditions of the Namib and Sahara deserts. These extremely arid regions receive less than 2.75 inches of annual rainfall. Compared to other bush elephants, desert elephants have longer legs, broader feet, and slightly smaller bodies. These resilient herbivores migrate between waterholes, following ancient routes based on seasonal food and water availability. Male desert elephants often roam alone over vast areas, while female-led family groups stay near rivers, where food is more plentiful. Their incredible adaptability is showcased by their ability to travel long distances, sometimes 43 miles in a single night, to find their favorite myrrh bushes.Desktop Version

Celebrating Pi Day
Celebrating Pi Day
Calculating the ratio of a circle"s circumference to its diameter is as easy as pi. Today is Pi Day, an event that celebrates this mathematical constant. This date was chosen because 3, 1, and 4 are the first three significant figures of pi (π) when it is written out. Pi is an irrational number, which means that it can"t be written as a fraction. When written out, its decimal representation goes on infinitely without repeating. The oldest attempts to calculate pi date back to ancient Babylon and Egypt, around 1900 BCE.Desktop Version

International Dark Sky Week
International Dark Sky Week
Imagine standing under a sky so dark that the Milky Way stretches across it like a luminous ribbon. This is the experience that International Dark Sky Week aims to bring back. Every April, during the week of the new moon (this year from April 21 to 27), we are invited to turn off our lights and gaze at the stars. The event was initiated by Jennifer Barlow, a high school student in 2003, to combat light pollution. One of the best places to experience the night sky"s beauty is Joshua Tree National Park in southeastern California, an International Dark Sky Park. Here, the absence of artificial light allows visitors to see the stars as our ancestors once did. Did you know that light pollution prevents us from seeing most of the stars in the Milky Way? By reducing it, we can reconnect with the universe"s beauty and wonder.Desktop Version
