Abstract
IN the application of mathematics to problems both of pure and applied science, there often arise differential equations which have no formal solution, or none convenient for numerical evaluation, but for which numerical values of the solutions are required. Though there are numerical methods of dealing with such situations, it would often be advantageous, as an alternative, to have mechanical means of evaluating solutions of differential equations, and this is the purpose of the ‘differential analyser’ of Dr. V. Bush, of the Massachusetts Institute of Technology.
