The metadata subpage is missing. You can start it via filling in this form or by following the instructions that come up after clicking on the [show] link to the right.

Do you see this on PREVIEW? then SAVE! before following a link. To find out more about the use of metadata for the management of Citizendium pages, see CZ:Metadata. You may see this box for one of two reasons. Either: A - New page has been created, or subpages template was added to an existing page B - Cluster move is in progress Click either the A or B link for further instructions. [Feel free to recommend improvements to the text or links in this template] A - For a New Cluster use the following directions Subpages format requires a metadata page. Using the following instructions will complete the process of creating this article's subpages. Click the blue "metadata template" link below to create the page. On the edit page that appears paste in the article's title across from "pagename =". You might also fill out the checklist part of the form. Ignore the rest. For background, see Using the Subpages template Don't worry--you'll get the hang of it right away. Remember to hit Save! the "metadata template". However, you can create articles without subpages. Just delete the {{subpages}} template from the top of this page and this prompt will disappear. :) Don't feel obligated to use subpages, it's more important that you write sentences, which you can always do without writing fancy code. [Feel free to recommend improvements to the text or links in this template] B - For a Cluster Move use the following directions The metadata template should be moved to the new name as the first step. Please revert this move and start by using the Move Cluster link at the top left of the talk page. The name prior to this move can be found at the following link.

This is a list of people who have made major conceptual breakthroughs in computer science.

• Backus, John (1924-2007) - inventor of FORTRAN
• Babbage, Charles (1791-1871) - early theorist for how a computing machine could be programmed
• Boole, George (1815-1864) - inventor of Boolean algebra
• Bricklin, Dan - invention of the first spreadsheet
• Church, Alonzo (1903-1995) - proof that first-order logic is undecidable; Church's thesis; creation of the lambda calculus
• Deutsch, David (1953 - ) - pioneer of quantum computing
• Jay Forrester (1918 -) - invention of core memory in 1953 (while working on the Whirlwind computer)
• Fourier, Joseph (1768-1830) - invented of Fourier series (long before electronic computers), making possible imaging algorithms for radar, xrays, etc
• Hamming, Richard (1915-1998) - invention of Hamming code for error correction
• Hopper, Grace (1906-1992) - invention of the compiler
• Knuth, Donald - created an encyclopedia of algorithms; pioneer in analysis of algorithms
• Leibnitz, Gottfried Wilhelm - discovered the binary number system (base 2)
• Lovelace, Ada (1815-1852) - wrote first computer program (instructions for calculating Bernoulli numbers on a Babbage machine)
• Ritchie, Dennis (1941- ) - Created C programming language, co-developer of Unix.
• Shannon, Claude (1916-2001) - association of boolean algebra with digital design; pioneering work in information theory
• Tukey, John (1915-2000) - introduction of the word "bit" as a contraction of binary digit and the word "software" in a computing context
• Turing, Alan (1912-1954) - theory of computability
• von Neumann, John (1903-1957) - first publication proposing use of same memory space for program instructions and data (idea now recognized as not created by JVN), merge sort algorithm, cellular automata
• Weiner, Norbert (1894 - 1964) Cybernetics.
• Zuse, Konrad (1910-1995) - likely invented the first electronic computer; likely the first designer to propose pipelining in processors
