Question:

Why should we use lambda expressions in Java?

Inactive
Keith K.
Answer:

Lambda expressions, which are now supported in Java 8, allow us to write a single line for a logical expression that would previously take many, many lines of code. This is important because code runs best when it is scalable, especially when dealing with any multicore. applications.

Question:

How do you integrate [math]e^{x^{2}}dx[/math]

Inactive
Keith K.
Answer:

Because [math]e^{x^{2}}dx[/math] is not an Elementary Function, i.e., it cannot be written as the composition of other functions, its antiderivative cannot be expressed as a function, and it's tough to deal with. However, there are some neat ways we can deal with this problem using Multivariable Calculus and The Gaussian Integral.

Question:

Why did the early-20th Century Progressive Movement ultimately disappear?

Inactive
Keith K.
Answer:

The failure of many Progressive ideas such as Prohibition, Protectionism, and a tight monetary policy, to mitigate the Great Depression led to many people growing disillusioned with the broader philosophy of President Theodore Roosevelt's Progressivism. The quintessential Progressive, Herbert Hoover, became so unpopular during the early part of the Great Depression that the Progressive Movement became temporarily discredited. Many of its ideas and guiding principles have since resurfaced in American political thought however, and President Hoover has seen his reputation among historians improve somewhat.
