Regardless of your age or family history, a stroke doesn't have to be inevitable. Stroke is a medical emergency. Think FAST. Act Fast.
It’s a special number. It shows up everywhere. In chemistry, physics, math, whether you’re talking circles or cycles or anything to do with a curve, you’re going to find pi in there somewhere. Pi is irrational, which means that you can’t calculate pi by dividing an integer by any other integer.
The coastal paradise of 4 million on the southern tip of South Africa, Cape Town, is to become the first modern major city in the world to completely run dry. And even though residents aren’t responsible, the burden of making sure it doesn’t happen rests largely on our ability to cut down on water usage.
The origin of the symbol zero has long been one of the world’s greatest mathematical mysteries. New carbon dating research commissioned by the University of Oxford’s Bodleian Libraries into the ancient Indian Bakhshali manuscript, held at the Bodleian, has revealed it to be hundreds of years older than initially thought, making it the world’s oldest recorded origin of the zero symbol that we use today.
Megalithic monuments are among the earliest and most permanent of archaeological structures, and so many of them were used, or more properly, have been used and reused for thousands of years. Their original intent is likely lost to the ages, but they may have had multiple functions as they were used by different cultural groups over the centuries and millennia.
Chandrasekhar became famous for his discoveries about the evolution of the stars. His work was vast, and he began early, developing his theory of stars’ evolution before he had even turned 20. Google is changing its logo globally to a doodle of him and the Chandrasekhar Limit. That refers to his calculation that once a star reaches 1.44 times the size of our own sun, it doesn’t form a white dwarf as expected but collapses, eventually becoming a black hole.
The 2015 Paris agreement established a global target for lowering greenhouse-gas emissions — aimed at keeping the atmosphere from warming by 2 degrees Celsius. One hundred and ninety-four countries have signed the treaty, which means that they have agreed to continue the process of the treaty on climate change mitigation. Nearly all the world’s countries agreed to create a system to measure their progress, and to continually strengthen their efforts.
A river in New Zealand has become the first in the world to be legally recognised as a living entity and granted the same rights as a human. The sacred river will be granted all the corresponding rights, duties and liabilities of a legal person after a 170-year battle led by a local Maori tribe…
India has created history today by successfully launching 104 satellites on a single mission, overtaking the previous record for most spacecraft launched at a single attempt, which currently stands at the thirty-eight orbited by a Dnepr in June 2014, of which thirty-two were deployed from the rocket itself while a thirty-third failed to separate. Four…
