{ Though history is usually written by the winners, this one was written by a loser :) Keep in mind there may appear errors, you can send me an email if you find some. ~drummyfish }

This is a brief summary of history of technology and computers (and some other things). For those who don't know history are doomed to repeated it.

{ A curious pattern of history is that the civilization -- or maybe rather the dominating superpowers -- are moving to the west, kind of like: middle East -> Greece -> Rome -> Holy Roman Empire -> England/France/Spain -> America. ~drummyfish }

The Universe began in singularity and started to exist with Big Bang almost 14 billion years ago. It went through several epochs during which it changed greatly: first there was the epoch of rapid inflation, up to about 10^-32 seconds, during which it expanded extremely rapidly. After this the fundamental forces (strong, weak, electromagnetic and gravitational) started to become separate, the universe was cooling down, it became transparent and then, after 200 million years, first stars started to form. After another 200 million years first galaxies started to form, including our own Milky Way galaxy. Our Earth formed some 4.5 billion years ago, along with the Moon. It seems life appeared about 3.8 billions years ago; about 600 million years ago multicellular life formed and 66 million years ago the dinosaurs went extinct, giving opportunity to mammals and eventually to us, humans.

The earliest known appearance of technology related to humans may likely be the use of stone tools by hominids in Africa some two and a half million years ago -- this is even before the appearance of modern humans, homo sapiens, that emerged roughly 600000 years ago. Learning to start and control fire was another key invention of the earliest men; this probably happened hundreds of thousands to millions years ago, even before modern humans. Around 8000 BC the Agricultural Revolution happened: this was quite a disaster -- as humans domesticated animals and plants, they had to abandon the comfortable life of hunters and gatherers and started to suffer the life of a farmer, full of extremely hard work in the fields (this can be seen e.g. from their bones). This led to the establishment of first cities that would later become city states (as the name says -- something between a city and a state, i.e. greatly independent cities with their own laws etc.). Some of the first such cities were Ur and Uruk in Mesopotamia, since around 5000 BC. Primitive writing can be traced to about 7000 BC to China. Wheel was another crucial piece of technology humans invented, it is not known precisely when or where it appeared, but it might have been some time after 5000 BC -- in Ancient Egypt The Great Pyramid was built around 2570 BC still without the knowledge of wheel. Around 4000 BC history starts with first written records. Humans learned to smelt and use metals approximately 3300 BC (Bronze Age) and 1200 BC (Iron Age). Abacus, one of the simplest digital devices aiding with computation, was invented roughly around 2500 BC. However people used primitive computation helping tools, such as bone ribs, probably almost from the time they started trading. Babylonians in around 2000 BC were already able to solve some forms of quadratic equations.

In Greek many city states, such as Athens, Delphi and Sparta formed -- Ancient Greek culture would be seen as the golden age of civilization that would lay foundations to everything we now take for granted; Greeks to some extent advanced technology (e.g. architecture) but especially cultivated art, philosophy and politics -- Athens are credited for inventing democracy (though an "early" version, they still had slaves and many classes of citizens without voting power). In 8th century BC Homer created the epic poems Iliad and Odyssey. In 6th century BC Pythagoras describes the Pythagorean theorem. After 600 BC the Greek philosophy starts to develop which would lead to strengthening of rational, scientific thinking and advancement of logic and mathematics. Some of the most famous Greek philosophers were Socrates, Plato, Aristotle and Diogenes. Around 400 BC camera obscura was already described in a written text from China where gears also seem to have been invented soon after. Around 300 BC Euklid wrote his famous Elements, a mathematical work that proves theorems from basic axioms. Ancient Greeks could communicate over great distances using Phryctoria, chains of fire towers placed on mountains that forwarded messages to one another using light. 234 BC Archimedes described the famous Archimedes screw and created an algorithm for computing the number pi. In 2nd century BC the Antikythera mechanism, the first known analog computer is made to predict movement of heavenly bodies. Romans are known to have been great builders, they built many roads and such structures as the Pantheon (126 AD) and aqueducts with the use of their own type of concrete and advanced understanding of physics.

44 BC Julius Caesar, most famous leader of Ancient Rome, is killed. Rome has to be mentioned as at its time it was the biggest world superpower -- though it was a greatly corrupt, imperialist empire heavily based on work of slaves, Rome advanced technology in many ways, e.g. by inventing concrete, building roads and very long lasting aqueducts. They build monuments that would last for thousands of years, e.g. the famous Colosseum.

Around 50 AD Heron of Alexandria, an Egyptian mathematician, created a number of highly sophisticated inventions such as a vending machine that accepted coins and gave out holy water, and a cart that could be "programmed" with strings to drive on its own.

In the 3rd century Chinese mathematician Liu Hui describes operations with negative numbers, even though negative numbers have already appeared before. In 600s AD an Indian astronomer Brahmagupta first used the number zero in a systematic way, even though hints on the number zero without deeper understanding of it appeared much earlier. In 9th century the Mayan empire is collapsing, though it would somewhat recover and reshape.

Year 476 is set to mark the fall of Roman empire (last roman emperor deposed) and by this the end of Antiquity and start of Middle Ages. Rome had been collapsing slowly but in its downfall it greatly resembled our current western society, it became split, people got spoiled, lost sense of morality, women started to demand more power and so on -- Roman empire was basically like the ancient times US (with a similar relationship to Greece as US has to the older, wiser Europe) with highly capitalist practices (free trade, ads, banks, insurance, even industries that achieved quite high mass production, ...), imperialism, military obsession, fascism, constant political fights, pragmatic thinking (e.g. rhetoric, the art of manipulation, was greatly preferred over excellence in art), mass entertainment and huge competitiveness -- this all led to its demise.

In 1429 Persian mathematician al-Kashi computed pi to about 14 digit accuracy which was a great leap in this discipline.

Around the year of our Lord 1450 a major technological leap known as the Printing Revolution occurred. Johannes Gutenberg, a German goldsmith, perfected the process of producing books in large quantities with the movable type press. This made books cheap to publish and buy and contributed to fast spread of information and better education. Around this time the Great Wall of China is being built.

They year 1492 marks the discovery of America by Christopher Columbus who sailed over the Atlantic Ocean, though he probably wasn't the first in history to do so, and it wasn't realized he sailed to America until after he died (he thought he sailed to India). This is sometimes taken to mark the end of Middle Ages and transition to Renaissance. This was a time of increased interest in rationality, science and art; Renaissance saw man as a potent creation of God, who is capable of creating on his own rather than being mere blind, obedient servant of God. Great many polymath lived at this time, most notably Leonardo da Vinci (probably gay) who was an excellent painter, explored human anatomy and even subjects such as astronomy and engineering. On one hand Renaissance brought beautiful art and new technology, on the other hand it further shifted society toward capitalism and selfish thinking, human became more self centered, egoistic and art became even more a matter of business -- for example the great painters infamously hired lesser artists to make copies of their paintings which were then sold almost like consumer products.

In 1642 Blaise Pascal, a french mathematician/inventor/philosopher, invented Pascaline, a simple mechanical calculator (however building on ideas dating back to antiquity), laying some very early foundations for automatic computation. (The Pascal programming language is named after him.) Shortly after Pascal another genius, Gottfried Wilhelm Leibniz, further developed some basic theory (related e.g. to binary system and algorithms) that would much later on evolve into computer science.

During 1700s a major shift in civilization occurred, called the Industrial Revolution -- this was another disaster that would lead to the transformation of common people to factory slaves and loss of their self sufficiency. The revolution spanned roughly from 1750 to 1850. It was a process of rapid change in the whole society due to new technological inventions that also led to big changes in how a man lived his daily life. It started in Great Britain but quickly spread over the whole world. One of the main changes was the transition from manual manufacturing to factory manufacturing using machines and sources of energy such as coal. Steam engine played a key role. Work became a form of a highly organized slavery system, society became industrionalized. This revolution became highly criticized as it unfortunately opened the door for capitalism, made people dependent on the system as everyone had to become a specialized cog in the society machine, at this time people started to measure time in minutes and lead very planned lives with less joy. But there was no way back.

In 1712 Thomas Newcomen invented the first widely used steam engine used mostly for pumping water, even though steam powered machines have already been invented long time ago. The engine was significantly improved by James Watt in 1776. Around 1770 Nicolas-Joseph Cugnot created a first somewhat working steam-powered car. In 1784 William Murdoch built a small prototype of a steam locomotive which would be perfected over the following decades, leading to a transportation revolution; people would be able to travel far away for work, the world would become smaller which would be the start of globalization. The railway system would make common people measure time with minute precision.

In 1792 Clause Chappe invented optical telegraph, also called semaphore. The system consisted of towers spaced up to by 32 km which forwarded textual messages by arranging big arms on top of the towers to signal specific letters. With this messages between Paris and Strasbourg, i.e. almost 500 km, could be transferred in under half an hour. The system was reserved for the government, however in 1834 it was hacked by two bankers who bribed the tower operators to transmit information about stock market along with the main message (by setting specific positions of arms that otherwise didn't carry any meaning), so that they could get an advantage on the market.

By 1800 Alessandro Volta invented an electric battery. In 1827 André-Marie Ampère publishes a further work shedding light on electromagnetism. After this electric telegraph would be worked on and improved by several people and eventually made to work in practice. In 1821 Michael Faraday invented the electromotor. Georg Ohm and especially James Maxwell would subsequently push the knowledge of electricity even further.

In 1822 Charles Babbage, a great English mathematician, completed the first version of a manually powered digital mechanical computer called the Difference Engine to help with the computation of polynomial derivatives to create mathematical tables used e.g. in navigation. It was met with success and further development was funded by the government, however difficulties of the construction led to never finishing the whole project. In 1837 Babbage designed a new machine, this time a Turing complete general purpose computer, i.e. allowing for programming with branches and loops, a true marvel of technology. It also ended up not being built completely, but it showed a lot about what computers would be, e.g. it had an assembly-like programming language, memory etc. For this computer Ada Lovelace would famously write the Bernoulli number algorithm.

In 1826 or 1827 French inventor Nicéphore Niépce captured first photography that survived until today -- a view from his estate named Le Gras. About an 8 hour exposure was used (some say it may have taken several days). He used a camera obscura and asphalt plate that hardened where the light was shining. Earlier cases of photography existed maybe as early as 1717, but they were only short lived.

Sound recording with phonatograph was invented in 1857 in Paris, however it could not be played back at the time -- the first record of human voice made with this technology can nowadays be reconstructed and played back. It wouldn't be until 1878 when people could both record and play back sounds with Edison's improvement of phonatograph. A year later, in 1879, Edison also patented the light bulb, even though he didn't invent it -- there were at least 20 people who created a light bulb before him. Pi at this time is evaluated to roughly 500 digit accuracy (using Machin's formula).

Around 1888 so called war of the currents was taking place; it was a heated battle between companies and inventors for whether the alternating or direct current would become the standard for distribution of electric energy. The main actors were Thomas Edison, a famous inventor and a huge capitalist dick rooting for DC, and George Westinghouse, the promoter of AC. Edison and his friends used false claims and even killing of animals to show that AC was wrong and dangerous, however AC was objectively better, e.g. by its efficiency thanks to using high voltage, and so it ended up winning the war. AC was also supported by the famous genius inventor Nikola Tesla who during these times contributed hugely to electric engineering, he e.g. invented an AC motor and Tesla coil and created a system for wireless transmission of electric power.

Also in 1888 probably the first video that survived until today was recorded by Lou Le Prince in Northern England, with a single lens camera. It is a nearly 2 second silent black and white shot of people walking in a garden.

1895 can roughly be seen as the year of invention of radio, specifically wireless telegraph, by Italian engineer and inventor Guglielmo Marconi. He built on top of work of others such as Hertz and Tesla and created a device with which he was able to wirelessly ring a bell at a distance over 2 km.

On December 17 1903 the Wright brothers famously performed the first controlled flight of a motor airplane which they built, in North Carolina. In repeated attempts they flew as far as 61 meters over just a few seconds.

From 1914 to 1918 there was World War I.

Around 1915 Albert Einstein, a German physicist, completed his General Theory of Relativity, a groundbreaking physics theory that describes the fundamental nature of space and time and gives so far the best description of the Universe since Newton. This would shake the world of science as well as popular culture and would enable advanced technology including nuclear energy, space satellites, high speed computers and many others.

Int 1907 Lee De Forest invented a practically usable vacuum tube, an extremely important part usable in electric devices for example as an amplifier or a switch -- this would enable construction of radios, telephones and later even primitive computers. The invention would lead to the electronic revolution.

In 1923 the research of mainly Edwin Hubble leads to concluding there exist other galaxies in the Universe besides our Milky Way, vastly expanding the size of known Universe.

In 1924 about 50% of US households own a car.

October 22 1925 has seen the invention of transistor by Julius Lilienfeld (Austria-Hungary), a component that would replace vacuum tubes thanks to its better properties, and which would become probably the most essential part of computers. At the time the invention didn't see much attention, it would only become relevant decades later.

In 1931 Kurt Gödel, a genius mathematician and logician from Austria-Hunagry (nowadays Czech Republic), published revolutionary papers with his incompleteness theorems which proved that, simply put, mathematics has fundamental limits and "can't prove everything". This led to Alan Turing's publications in 1936 that nowadays stand as the foundations of computer science -- he introduced a theoretical computer called the Turing machine and with it he proved that computers, no matter how powerful, will never be able to "compute everything". Turing also predicted the importance of computers in the future and has created several algorithms for future computers (such as a chess playing program).

In 1938 Konrad Zuse, a German engineer, constructed Z1, the first working electric mechanical digital partially programmable computer in his parents' house. It weighted about a ton and wasn't very reliable, but brought huge innovation nevertheless. It was programmed with punched film tapes, however programming was limited, it was NOT Turing complete and there were only 8 instructions. Z1 ran on a frequency of 1 to 4 Hz and most operations took several clock cycles. It had a 16 word memory and worked with floating point numbers. The original computer was destroyed during the war but it was rebuilt and nowadays can be seen in a Berlin museum. Zuse also soon created what's regarded as the first programming language, Plankalkul.

From 1939 to 1945 there was World War II.

In hacker culture the period between 1943 (start of building of the ENIAC computer) to about 1955-1960 is known as the Stone Age of computers -- as the Jargon File puts it, the age when electromechanical dinosaurs ruled the Earth.

In 1945 the construction of the first electronic digital fully programmable computer was completed at University of Pennsylvania as the US Army project. It was named ENIAC (Electronic Numerical Integrator and Computer). It used 18000 vacuum tubes and 15000 relays, weighted 27 tons and ran on the frequency of 5 KHz. Punch cards were used to program the computer in its machine language; it was Turing complete, i.e. allowed using branches and loops. ENIAC worked with signed ten digit decimal numbers. Also in 1945 on July 16 Americans detonated the first nuclear bomb in history as a test, later on that year USA used two nuclear bombs to murder hundreds of thousands of civilians in Japanese cities Hiroshima and Nagasaki. Around this time John von Neumann, a great genius with wide areas of interest, is also making great contributions to computer science, famously e.g. proposing the von Neumann computer architecture in which the program and data are stored in the same memory -- a concept that would be highly utilized in the future.

Among hackers the period between 1961 to 1971 is known as the Iron Age of computers. The period spans time since the first minicomputer (PDP1) to the first microprocessor (Intel 4004). This would be followed by so called elder days.

On July 20 1969 first men landed on the Moon (Neil Armstrong and Edwin Aldrin) during the USA Apollo 11 mission. This tremendous achievement is very much attributed to the cold war in which USA and Soviet Union raced in space exploration. The landing was achieved with the help of a relatively simple on-board computer: Apollo Guidance Computer clocked at 2 MHz, had 4 KiB of RAM and about 70 KB ROM. The assembly source code of its software is nowadays available online.

Shortly after, on 29 October 1969, another historical event would happen that could be seen as the start of perhaps the greatest technological revolution yet, the start of the Internet. The first letter, "L", was sent over a long distance via ARPANET, a new experimental computer packet switching network without a central node developed by US defense department (they intended to send "LOGIN" but the system crashed). The network would start to grow and gain new nodes, at first mostly universities. The network would become the Internet.

1st January 1970 is nowadays set as the start of the Unix epoch. It is the date from which Unix time is counted. During this time the Unix operating system, one of the most influential operating systems was being developed at Bell Labs, mainly by Ken Thompson and Dennis Ritchie. Along the way they developed the famous Unix philosophy and also the C programming language, perhaps the most influential programming language in history. Unix and C would shape the technology far into the future, a whole family of operating systems called Unix-like would be developed and regarded as the best operating systems thanks to their minimalist design.

By 1977 ARPANET had about 60 nodes.

August 12 1981 would see the released of IBM PC, a personal computer based on open, modular architecture that would immediately be very successful and would become the de-facto standard of personal computers. IBM PC was the first of the kind of desktop computers we have today. It had 4.77 MHz Intel 8088 CPU, 16 kB of RAM and used 5.25" floppy disks.

In 1983 Richard Stallman announced his GNU project and invented free (as in freedom) software, a kind of software that is freely shared and developed by the people so as to respect the users' freedom. This kind of ethical software stands opposed to the proprietary corporate software, it would lead to creation of some of the most important software and to a whole revolution in software development and its licensing, it would spark the creation of other movements striving for keeping ethics in the information age.

1985: on November 20 the first version of the Windows operating system was sadly released by Microsoft. These systems would become the mainstream desktop operating systems despite their horrible design and they would unfortunately establish so called Windows philosophy that would irreversibly corrupt other mainstream technology. Also in 1985 one of the deadliest software bugs appeared: that in Therac-25, a medical radiotherapy device which fatally overdosed several patients with radiation.

On April 26 1986 the Chernobyl nuclear disaster happened (the worst power plant accident in history) -- in north Ukraine (at the time under USSR) a nuclear power plant exploded, contaminated a huge area with radioactivity and released a toxic radioactive cloud that would spread over Europe -- many would die either directly or indirectly (many years later due to radioactivity poisoning, estimated at many thousands). The Chernobyl area would be sealed in the 30 km radius. It is estimated the area won't be habitable again for several thousands of years.

Around this time Internet is not yet mainstream but it is, along with similar local networks, working and has active communities -- there is no world wide web yet but people are using Usenet and BBSes for "online" discussions with complete strangers and developing early "online cultures".

At the beginning of 1991 Tim Berners-Lee created the World Wide Web, a network of interlinked pages on the Internet. This marks another huge step in the Internet revolution, the Web would become the primary Internet service and the greatest software platform for publishing any kind of information faster and cheaper than ever before. It is what would popularize the Internet and bring it to the masses.

Shortly after the Soviet Union dissolved and on 25 August 1991 Linus Torvalds announced Linux, his project for a completely free as in freedom Unix-like operating system kernel. Linux would become part of GNU and later one of the biggest and most successful software projects in history. It would end up powering Internet servers and supercomputers as well as desktop computers of a great number of users. Linux proved that free software works and surpasses proprietary systems.

After this very recent history follows, it's hard to judge which recent events will be of historical significance much later. 1990s have seen a huge growth of computer power, video games such as Doom led to development of GPUs and high quality computer graphics along with a wide adoption of computers by common people, which in turn helped the further growth of Internet. In around mid 90s the web overtook gopher in popularity and started to become the forefront of the Internet. Late 90s saw the rise of the "open source" movement (OSI was established in 1998). Worthy of mention is also the first animal cloned from an adult cell, sheep named Dolly, in 1996. In 1997 computer first beat human world chess champion, it was the famous Kasparov vs Deep Blue match. Year 2000 was infamously preceded by the Y2K hysteria, the fear of technological collapse that was to be caused by computers flipping from year 99 to 00 -- this of course didn't happen. With the year 2000 21st century starts. Shortly after 2000 Lawrence Lessig founded Creative Commons, an organization that came hand in hand with the free culture movement inspired by the free software movement. At this point over 50% of US households had a computer. In 2003 the whole human DNA was sequenced after 13 years of international collaborative effort. From 2005 we've seen a boom of social networks like Facebook, Twitter and YouTube and also skyrocketing popularity of online and massively online games, owing a lot to the gigantic success of World of Warcraft; all of these contributed to making Internet and computers one of the most mainstream and lucrative things, ruining everything. Cell phones became a commonly owned item and after about 2005 so called "smart phones" and other "smart" devices replaced them as a universal communication device capable of connecting to the Internet. Year 2010 seems to be the turning point beyond which societal decline accelerated immensely; 1990s seem to have been the peak of society, after the year 2000 society started to slowly decline but by inertia things were still relatively good for about another decade. In 2011 Minecraft was released. After this we've seen the rise of Bitcoin and other cryptocurrencies. Before 2020 we've also seen a brief spike in popularity of VR (that would diminish again) and a huge advancement in neural network Artificial Intelligence which will likely be the topic of the future. 2022 saw the release of ChatGPT, the AI chatbot that made a worldwide sensation by its human-like nature and intelligence -- the event will likely be seen as the moment of transition to a truly human-like AI. Quantum computers are being highly researched with already existing primitive prototypes; this will also likely be very important in the following years. Besides AI there were also drones, electromobiles, robotic Mars exploration and other things. However the society and technology have been in decadence for some time now, capitalism has pushed technology to become hostile and highly abusive to users, extreme bloat of technology causes highly inefficient, extremely expensive and unreliable technology. In addition society is dealing with a lot of serious issues such as the global warming and many people are foreseeing a collapse of society.
