Haskell Brooks Curry (/ˈhæskəl ˈkɜːri/; September 12, 1900 – September 1, 1982) was an American mathematician and logician. Curry is best known for his work in combinatory logic; while the initial concept of combinatory logic was based on a single paper by Moses Schönfinkel, much of the development was done by Curry. Curry is also known for Curry's paradox and the Curry–Howard correspondence. There are three programming languages named after him, Haskell, Brook and Curry, as well as the concept of currying, a technique used for transforming functions in mathematics and computer science.
Curry was born on September 12, 1900, in Millis, Massachusetts, to Samuel Silas Curry and Anna Baright Curry, who ran a school for elocution. He entered Harvard University in 1916 to study medicine but switched to mathematics before graduating in 1920. After two years of graduate work in electrical engineering at MIT, he returned to Harvard to study physics, earning a MA in 1924. Curry's interest in mathematical logic started during this period when he was introduced to the Principia Mathematica, the attempt by Alfred North Whitehead and Bertrand Russell to ground mathematics in symbolic logic. Remaining at Harvard, Curry pursued a Ph.D. in mathematics. While he was directed by George Birkhoff to work on differential equations, his interests continued to shift to logic. In 1927, while an instructor at Princeton University, he discovered the work of Moses Schönfinkel in combinatory logic. Schönfinkel's work had anticipated much of Curry's own research, and as a consequence, he moved to Göttingen where he could work with Heinrich Behmann and Paul Bernays, who were familiar with Schönfinkel's work. Curry was supervised by David Hilbert and worked closely with Bernays, receiving a Ph.D. in 1930 with a dissertation on combinatory logic.

In mathematics and computer science, a higher-order function (also functional, functional form or functor; not to be confused with the functor concept in category theory) is a function that does at least one of the following:
All other functions are first-order functions. In mathematics higher-order functions are also known as operators or functionals. The differential operator in calculus is a common example, since it maps a function to its derivative, also a function.
In the untyped lambda calculus, all functions are higher-order; in a typed lambda calculus, from which most functional programming languages are derived, higher-order functions are values with types of the form .
The map
function, found in many functional programming languages, is one example of a higher-order function. It takes as arguments a function f and a list of elements, and as the result, returns a new list with f applied to each element from the list. Another very common kind of higher-order function in those languages which support them are sorting functions which take a comparison function as a parameter, allowing the programmer to separate the sorting algorithm from the comparisons of the items being sorted. The C standard function qsort
is an example of this.

A brief exposition of Curry's Paradox, first published by Haskell Curry. It seems to show that, given a special kind of conditional sentence and some very basic logical rules, anything is derivable.

This video describes how programming languages like Haskell which support only one arguments but allow multiple parameters.
Haskell 6a : Higher order functions Haskell functions can take functions as parameters and return functions as return values. A function that does either of those is called a higher order function. Higher order functions aren't just a part of the Haskell experience, they pretty much are the Haskell experience. It turns out that if you want to define computations by defining what stuff is instead of defining steps that change some state and maybe looping them, higher order functions are indispensable. They're a really powerful way of solving problems and thinking about programs. Curried functions Every function in Haskell officially only takes one parameter. So how is it possible that we defined and used several functions that take more than one parameter so far? Well, it's a clever tric...
A short video explaining the concept of curring, using JavaScript. This is part of a series, where are learning functional programming using JavaScript. Currying is when a function, instead of taking all arguments at one time, takes the first one and returns a new function that takes the second one and returns a new function which takes the third one, and so forth, until all arguments have been fulfilled.

Abstract Rust is a new systems-programming language that is becoming increasingly popular. It aims to combine C++’s focus on zero-cost abstractions with numerous ideas that emerged first in academia, most notably affine and region types (“ownership and borrowing”) and Haskell’s type classes (“traits”). One of the key goals for Rust is that it does not require a garbage collector. In this talk, I’ll give a brief overview of Rust’s key features, with a focus on the type system. I’ll talk about how we leverage a few core features to offer a variety of APIs – ranging from efficient collections to various styles of parallel programming – while still guaranteeing memory safety and data-race freedom.
