TLDR; Neumann was just on another level with his work. ), Gottlob Frege defined Frege’s propositional calculus (first-order logic), and predicate calculus. endstream endobj 583 0 obj <> endobj 584 0 obj <> endobj 585 0 obj <>stream 0000009009 00000 n Also, he served on committees developing the ALGOL system of programming languages. (fun fact: the Frege programming language is named after him!). xڍ�1 Alongside his colleague Robert Cailliau, he sent the first HTTP communication between a server and a client. John von Neumann is a highly notable physicist and known for being on the manhattan project. (fun fact: she is credited for popularizing the term debugging!). startxref One of my favorite talks have been by Donald Knuth. When he designed it was programmed by punch-cards, and the numeral system was decimal. history of computing, as a separate subject, may itself become irrelevant. Basically if you have not heard of it — I am very certain you have seen the model he came up: One of his biggest principles was the idea that data and program can be saved on the same space. Alongside Backus, Peter Naur made major contributions in the definition ALGOL 60, and pioneered the Backus-Naur Form. He wrote about it in his paper “Explication de l’Arithmétique Binaire”. He formalized a lot of concepts in theoretical Computer Science with his work on the Turing Machine. Following Euclid, notes about recipes, etc. 126 0 obj<>stream His name roughly translates to Algoritmi, in Latin, and he develops a technique called Algorism. Specifically: All these led him to pioneer the idea of representing and manipulating knowledge using symbols and logic. h�bbd```b``9 "�@$�40{/X|3�d���� ҄D�_�nV@��m;�mY Interestingly, Backus wrote an article on “Can Programming Be Liberated from the von Neumann Style? How did simple changes in voltage develop machines such as computers? He started working on a new system of logic in his work — Ars magna. 0000007963 00000 n It seems common to us now to list things out in the order we will do them in. 0000006913 00000 n ;"��w�W����v�Ft%��;::��Aekhk�#c�Ҹ��Ia3��L]�d��̽._6�v{\������է��o�>Wl��ʾ[yD"k��¸Ӱ� �Uy"��9`��@�&����7 �[�ʽ>NN2�����M%D0*`:\}B�#�HgT���ȟ�0�`��U�q����K�a��˧)�9�;� ���T�ծ��Z �6~�Z`q)�j��s?��#�Bc�e�[��\�t9=��8�����ה�>0>`>���wԐ��UF��K��k�>z���TF�}q�86'6�n�Ō3���@� ` �ux� His work still remains: Leibniz also discovered the modern binary system that we use today . This was an important milestone in Mathematics, and in engineering. He is the first one to develop the concept of the algorithm in Mathematics. These were vital in the development of theoretical computer science. Most logic within electronics now stands on top of his work.

He designed it, but it wasn’t until 1940s that it was actually built. Shannon founded the base of the sub-field of information theory. He also lives in New York — so meet him if you have a chance. They designed the TCP/IP protocols, and the architecture of how the Internet would be laid out. xref %%EOF It incorporated an Arithmetic and Logic unit (ALU), integrated memory, and control flow statements. Elements was instrumental in the development of logic & modern science. Please expand on things I have written through comments. (His work and his papers are deeply insightful — you should give them a glance), Grace Hopper was first exposed to Computer Science when she was assigned a role to work on the first large-scale digital computer at Harvard. I believe that it is fundamental to have an overview of the history that later formed Computer Science. Also I wasn’t able to include every individual along the way, but let me know if I’ve missed anyone obvious. He concentrated his work on efficiently and reliably transmitting and storing information. CSCA0101 Computing Basics 3 History of Computers Definition of Computer • Computer is a programmable machine. The pic-ture of Grace Hopper in Chapter 3 is from the Computer History … ����[�_��l8� j�D!��C�]�v��F� *�J"�!�!KC��# He designed and the Von Neumann architecture. The traffic light in Section 2.1 is from iStock-Photo, and the rotary traffic signal is from the Wikimedia Commons. He’s also widely known to be the creator of TeX typesetting system, for The Art of Computer Programming book, for the KMP (Knuth–Morris–Pratt) algorithm, and much much more. People know work of individuals such … He made an incredible achievements in symbolic logic, and made developments in First-order logic. He was the pioneer of what we call Boolean Logic, which as we know is the basis of the modern digital computer. It showed the general public that tools can be built, using Mathematics, to simplify things e.g. A Functional Style and Its Algebra of Programs”, which is worth reading! In her notes on the engine she wrote the first algorithm that ran on any machine. Charles Babbage, the father of computing, pioneered the concept of a programmable computer. He also has a magnificent beard.). Next, we all know the great Alan Turing. 0000002490 00000 n %%EOF trailer The Apollo Guidance Computer image in Section 1.2.3 was released by NASA and is in the public domain. Project. Leslie Lamport laid out the foundations for the field of distributed systems. It is important to explore the process of how these concepts are discovered. But, he’s also important in the history of Computer Science. Sorel Reisman, Computer Society 2011 President, originally suggested this project to the History … For example, Sieve of Eratosthenes, Euclid’s algorithms, and methods for factorization square roots. were the closest thing to how we think at algorithms today. ), Then came a man most computer scientists should know about — George Boole. The Backus-Naur Form is used to describe and depict programming languages. Russell proposed a solution that avoids Russell’s paradox by first creating a hierarchy of types, then assigning each mathematical entity to a type. Lambda calculus played a big part in the development of functional programming languages. It is made publicly available in this format as collaboration between the Computer Society and the author, who retains all rights while allowing this public version. Let me know if I have gotten anything incorrect or have not made anything clear! 0 His talk is titled “Let’s Not Dumb Down the History of Computer Science”. The history of computer dated back to the period of scientific ... (2000). (fun fact: the boolean data-type is named after him! 0 Al-Khwārizmī is considered to be the grandfather of Computer Science. Thanks for reading! �0Ew�B���ȱ�Jǜ�C�P|��JBB�P��}�|�"X4o�z/��S8����0 -;��n[��ע4}��GȄMG*)1��y����Lh�. This idea implies that a machine can alter both its program and its internal data. 0000000016 00000 n Once If you get a chance, please watch it! Its architecture was like the architecture of the modern computer — he called his mechanical computer the Analytical Engine. But, in Mathematics at that time — it was not a common idea. Dijkstra also formulated the Dining philosophers problem. The courses are intended to be equivalent in content but have a broader appeal to those in di erent disciplines.
