At first glance, it may appear similar to SQL. However, MDX is a completely new language. SQL was designed to query dimensional data structures, called tables, where data are organized in rows and columns. In OLAP, data are organized around multiple measures, dimensions, hierarchies, and levels.
Yield (in megatons) of the B83 nuclear weapon, which is the largest nuclear weapon currently in the U.S. stockpile. 1.24. Shortest range (in miles) of a U.S. nuclear shell. Known as the âDavy Crockett,â the W54 weapon, a small nuclear warhead with a weight of 51 pounds, was fired by a recoilless gun mounted on a jeep. Number of U.S. nuclear weapons used in wartime, against Hiroshima on August 6, 1945 and Nagasaki on August 9, 1945.
What makes nuclear weapons impressive and terrible is that their default yield-to-weight ratio â that is, the amount of bang per mass, usually expressed in terms of kilotons per kilogram (kt/kg) â is much, much higher than conventional explosives. Take TNT for example. A ton of TNT weighs, well, a ton.
