In particular on popular link-sharing website Reddit, where users have on multiple occasions erroneously attributed the photo's location as "Where the Baltic and North Sea meet" and the two types of water as being completely incapable of ever mixing, instead perpetually butting against each other like a boundary on a map. You also may have seen a variation on the photo featuring the same phenomenon, taken by photographer Kent Smith while on a July 2010 cruise in the Gulf of Alaska. That photo too has been circulating the web for some time, though the misconceptions about it seem to be less thanks to Smith's explanation of the photo on his Flickr page.

Sabrina Pasterski

beststudytutorial.blogspot.comWe all know about Sabrina if I not know than u must heard about the "PHYSICS GIRL".

The first-generation Cuban-American woman has already received job offers from Jeff Bezos, the founder of, and aerospace developer and manufacturer Blue Origin. NASA has also shown interest in the young physicist. Pasterski’s study seeks to explore black holes and spacetime and she is particularly concentrated on explaining gravity through the context of quantum mechanics.
