Ever wondered, why seas around the world are named like that?
Red Sea
Named after seasonal blooming of cyanobacteria called Trichodesmium erythraeum that turn water from blue to red near the sea shores.
Though the sea is named red but the colour is blue.
Black sea
As per Greek mythology, sea was harsh and difficult to navigate in ancient times and looked black during heavy storms.
Other theory is this sea has hydrogen sulfide below 200 mt surface that supports microbes that produce black sediments therefore Black sea.
Yellow Sea
The numerous rivers that flow into the sea, carrying sediment and nutrients, contribute to its yellowish shade.
Why is international date line zig-zag where as prime meridian is a straight line?
Do they hold any significance?
A 🧵thread
The Prime Meridian is a straight line running from the North Pole to the South Pole, and it serves as the reference point for measuring longitude on the Earth. It's a single fixed line at 0 degrees longitude.
Without prime meridian there would be
-No common reference point for time and location
-No standardized system for navigation
-No geographic coordinates
-No global communication and celestial navigation
Prime meridian serves as a reference for time zones.
Are Nobel prizes really given to the deserving? If no, then what are the problems with the Nobel prize?
A surprising and thought provoking thread 🧵
Nobel prizes are given to people whose work has had the maximum impact on the maximum number of people. The award is typically given 10 to 15 years after the research has been done to understand the efficacy of the work but this has not always been followed.
Problem with the Nobel prize is that they lack transparency, lack diversity, at times trigger criticism & controversy, are sometimes wrongly given, maintain secrecy as details of the selection process are sealed from public view for 50 years and are more conservative in approach.
