Exactly what the title says. The prompt is this: Chose an actual example of scientific explanation, and use it to evaluate Hempel's and Ruben's accounts of explanation. I am not understanding the second part, how I am supposed to use an example to evaluate Hempel's and Ruben's accounts of explanation (Hempel's DN model and Ruben's causal single statement view of explanation). Am I supposed to present the example in the context of Hempel's and Ruben's accounts of explanation? Would appreciate some clarification. Secondly, I was wonder if you guys knew of any introductory or somewhat moderate treatment of philosophy of math. I think I have a decent math background at the moment but not graduate school level. Are there any accessible and readable material of that field? Thanks.
