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 known as the Iwi. Rights of Nature or granting legal personhood to nature may finally provide balance in legal systems around the world that tend to view nature as only an economic resource for humans.
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 Russia’s Dnepr in June 2014, of which thirty-two were deployed from the rocket itself while a thirty-third failed to separate. Salute to ISRO scientists!
Back in the pre-internet days, if someone asked you a tricky question, you had a couple of options. You could see if anyone you knew had the answer. You could pull out an encyclopaedia. Or you could head down to the library to carry out research. Whichever one you opted for, it was almost certainly more complicated and time-consuming than what you’d do today: Google it.
Zodiacal signs are of equal length whereas the zodiacal constellations are not equal in length. Whether or not you believe horoscopes are worthwhile, it seems Ophiuchus won’t be disrupting our astrological zodiac any time soon.
