text_A: Paul Thomas Anderson penned a tragedy that involved psychology.
text_B: Old name '' `` EJS '' '' Easy Java Simulations or new name since 2014 EJSS , or Easy JavaScript Simulations , is an open-source software tool , part of the Open Source Physics project , designed for the creation of discrete computer simulations .. open-source software. open-source software. Open Source Physics. Open Source Physics. A discrete computer simulation , or simply a computer simulation , is a computer program that tries to reproduce , for pedagogical or scientific purposes , a natural phenomenon through the visualization of the different states that it can have .. computer simulation. computer simulation. Each of these states is described by a set of variables that change in time due to the iteration of a given algorithm .. In creating a simulation with the help of EJSS , the user does not program the simulation at the level of writing code , instead the user is working at a higher conceptual level , declaring and organizing the equations and other mathematical expressions that operate the simulation .. EJSS handles the technical aspects of coding the simulation in the Java programming language , thus freeing the user to concentrate on the simulation 's content .. The generated Java or JavaScript code can , in terms of efficiency and sophistication , be taken as the creation of a professional programmer .. EJSS is written in the Java programming language and the created simulation are in Java or JavaScript .. Java Virtual Machines -LRB- JVM -RRB- are available for many different platforms ; a platform for which a JVM is available can run Java programs .. Though Java applets were popular before 2014 , JavaScript Applets outputs can be run on almost any device now , including Android and iOS .. EJSS has its own format for storing the simulations , which is based on XML , EJS and EJSS and carries the extension .. xml , .. ejs and .. ejss .. It contains not only the code for the simulation , but also the rest of the things , like the html introduction .
