π International Day of Mathematics – 14th March Logic • Discovery • Innovation • Infinite Possibilities International Day of Mathematics (IDM) is celebrated globally on 14th March each year. It was proclaimed by UNESCO in 2019 to highlight the essential role of mathematics in science, technology, education, and sustainable development. The date 14th March (3.14) is also widely recognized as Pi Day , symbolizing the mathematical constant Ο (pi). Mathematics is the language of patterns. It explains the universe—from atoms to galaxies. π Why 14th March Matters Mathematics is foundational to: Engineering and architecture Medicine and data science Artificial intelligence Climate modeling Economics and finance Space exploration Without mathematics, modern civilization would not function. π Mathematics in Everyday Life We use mathematics daily through: Time and measurement Banking and budgeting Technology and communication Navigation and transportation Construction and design Even simp...
It
doesn’t! The oxygen level of the planet has varied quite dramatically in the
last 500 million years. It was 35 per cent during the Carboniferous period, around
300 million years ago; as the climate, cooled and land plants died off, oxygen
fell to as low as 12 per cent by the beginning of the Triassic. Back then, the
air at sea level would have felt thinner than at the top of the Alps today.
Burning
fossil fuels has reduced oxygen levels very slightly – about 0.057 per cent
over the last 30 years. Deforestation only has a small effect because when
rainforest is cut down, other plants are usually grown in its place. But it’s
marine phytoplankton (plant plankton), rather than trees, that produces about
75 per cent of atmospheric oxygen. Global warming will have a significant
impact on phytoplankton, which is a much more serious threat to oxygen levels.
