By any standard, Knowledge Graph and Satori are already huge databases—but they aren't really "databases" in the traditional sense. Rather than being based on relational or object database models, they are graph databases based on the same graph theory approach used by Facebook’s Open Graph to map relationships between its users and their various activities. Graph databases are based on entities (or “nodes”) and the mapped relationships (or "links") between them. They’re a good match for Web content, because in a way, the Web itself is a graph database—with its pages as nodes, and relationships represented by the hyperlinks connecting them. … [Read more...] about How Google and Microsoft taught search to “understand” the Web

To build a bomb, scientists needed large amounts of unstable, radioactive uranium or plutonium. Uranium was easier to obtain than plutonium but scientists thought that plutonium might provide a quicker route to developing the bomb, according to the Department of Energy. They decided to try both and built nuclear reactors for each element — the Oak Ridge uranium reactor in eastern Tennessee and the Hanford plutonium reactor in Washington. … [Read more...] about What was the Manhattan Project?
The battle was a close affair that could have been a Roman victory. The Vandal forces were led or co-led by a man named Gunderic, while the Roman forces were led by a general named Castinus, who tried to starve the Vandal forces by cutting off their supply lines, notes Jeroen W.P. Wijnendaele, a post-doctoral research fellow at Ghent University, in his book "The Last of the Romans: Bonifatius — Warlord and comes Africae" (Bloomsbury, 2015). … [Read more...] about Who Were the Vandals?
