Celebrating Pi Day
Celebrating Pi Day
Long before pi had a name, people were drawn to its mystery. Every year on March 14, Pi Day highlights one of math"s most recognisable constants. The date reflects the first three digits of pi (π), the ratio of a circle"s circumference to its diameter: 3.14. Pi"s infinite, nonrepeating decimal has fascinated thinkers for a long time. The modern celebration began in 1988, when physicist Larry Shaw marked the day with a fitting tribute: serving pie.Desktop Version
Armbrug bridge, Amsterdam, Netherlands
Armbrug bridge, Amsterdam, Netherlands
Some bridges in Amsterdam just get you across a canal. The Armbrug does more—it seems to wave hello as you pass. Nestled over the Oudezijds Voorburgwal canal, its name, meaning "arm bridge," refers to the nearby Oudezijds Armsteeg (Old Side Arm Alley), not a literal limb, but it"s easy to imagine it greeting cyclists and pedestrians along the way.Desktop Version

Sgwd yr Eira waterfall, Brecon Beacons National Park, Wales
Sgwd yr Eira waterfall, Brecon Beacons National Park, Wales
Water spills in clean lines at Sgwd yr Eira, one of South Wales" most distinctive waterfalls. Its Welsh name means "Waterfall of Snow," referring to the pale curtain of water sliding over the rock face. What sets this waterfall apart is access. A narrow path leads visitors behind the falling water, immersing them in sound, light and movement at close range. Sgwd yr Eira lies within Brecon Beacons National Park, often called "Waterfall Country" for its network of rivers and falls carved into wooded gorges. Well-marked trails connect this waterfall to others along the River Hepste, making it a popular stop on longer hikes. Above the valleys, the landscape opens into rolling moorland and long ridgelines where upland paths are shaped by wind and changing weather. These contrasts define the Brecon Beacons, where open, exposed uplands give way to sheltered water, tying the landscape together.Desktop Version

Bláhver, Hveravellir, Iceland
Bláhver, Hveravellir, Iceland
Have you ever wondered what happens when fire, ice and time negotiate the same territory? Iceland"s Hveravellir geothermal field has the answer. In this highland hotspot, energy from the Earth"s interior meets the icy surface, triggering a volatile dialogue between pressure, temperature and stone. Fumaroles hiss, steam curls into the air and the ground paints itself with sulphur whites, rust reds and ochre yellows—not only artistry, but chemical reactions driven by extreme heat. In today"s image, Bláhver, a natural hot spring, dazzles in electric blue. Its colour comes from mineral- and silica-rich waters that reflect light on the surface.Desktop Version

International Day of Forests
International Day of Forests
If Earth had a maintenance crew, forests would be spearheading it. They absorb carbon emissions, reduce soil erosion, safeguard biodiversity, influence rainfall and help maintain clean water supplies. They still cover about 31% of the world"s land area, yet their continued decline shows how vulnerable these natural systems have become. Vast stretches continue to be cleared for agriculture, infrastructure and resource extraction, weakening ecosystems at an alarming rate.Desktop Version
Short-beaked echidna, Adelaide Hills, Australia
Short-beaked echidna, Adelaide Hills, Australia
An egg-laying mammal. No teeth. Reptilian gait. Built-in body armour. If the short-beaked echidna sounds like a checklist of contradictions, that"s because it is—and it owns it. Native to Australia, Tasmania and parts of New Guinea, it"s one of the few surviving monotremes, or mammals that lay eggs. Despite the headlines, it still qualifies as a mammal: it has fur, produces milk and is warm-blooded. The twist? Milk is released through specialised skin patches rather than nipples, leaving the young to lap it up.Desktop Version
Happy St. Patricks Day!
Happy St. Patricks Day!
St. Patrick, the patron saint of Ireland, was born in Roman Britain around the late 4th or early 5th century. According to legend, at 16, he was kidnapped by Irish raiders and brought to Ireland as a slave. After escaping, he returned home and later became a missionary, spreading Christianity across the island. He is famously associated, according to later tradition, with using the shamrock to explain the Holy Trinity. His legacy of faith has made St. Patrick"s Day a global celebration.Desktop Version

22 June is World Rainforest Day, a global moment and a year-round call to protect the world"s remaining rainforests. These ecosystems aren"t just dots on the map.
