Humans learn how to use fire
Fire is the rapid oxidation of a material in the exothermic chemical process of combustion, releasing heat, light, and various reaction products.[ -
5000 BCE
Humans invent the wheel
In its primitive form, a wheel is a circular block of a hard and durable material at whose center has been bored a hole through which is placed an axle bearing about which the wheel rotates when torque is applied to the wheel about its axis. The wheel and axle assembly can be considered one of the six simple machines. When placed vertically under a load-bearing platform or case, the wheel turning on the horizontal axle makes it possible to transport heavy loads. -
3100 BCE
Writing systems were invented
A writing system is a method of visually representing verbal communication, based on a script and a set of rules regulating its use. While both writing and speech are useful in conveying messages, writing differs in also being a reliable form of information storage and transfer.[1] Writing systems require shared understanding between writers and readers of the meaning behind the sets of characters that make up a script. -

Paper was invented
Paper is a thin sheet material produced by mechanically and/or chemically processing cellulose fibres derived from wood, rags, grasses or other vegetable sources in water, draining the water through fine mesh leaving the fibre evenly distributed on the surface, followed by pressing and drying. -

The printing press
A printing press is a mechanical device for applying pressure to an inked surface resting upon a print medium thereby transferring the ink. It marked a dramatic improvement on earlier printing methods in which the cloth, paper or other medium was brushed or rubbed repeatedly to achieve the transfer of ink, and accelerated the process. Typically used for texts, the invention and global spread of the printing press was one of the most influential events in the second millennium. -
Janssen microscope
Janssen has been associated with the invention of the single lens (single) and the compound (two or more lens) microscope. He is said to have built a 9x instrument, which is sometimes claimed to have been made with the help of his father (or even built entirely by the latter), 10 with an invention date commonly given as 159011 12 (or sometimes 1595), while trying to find a way to get even higher magnification lenses to help people with seriously impaired sight. -
Galileo's telescope
A refracting telescope (also called a refractor) is a type of optical telescope that uses a lens as its objective to form an image (also referred to a dioptric telescope). -
Watt steam machine was invented
A steam engine is a heat engine that performs mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force is transformed, by a connecting rod and flywheel, into rotational force for work. -
Electricity Volta
Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. -
Steam locomotive
A steam locomotive is a type of railway locomotive that produces its pulling power through a steam engine. These locomotives are fuelled by burning combustible material—usually coal, wood, or oil—to produce steam in a boiler -
Steamboat
A steamboat is a boat that is propelled primarily by steam power, typically driving propellers or paddlewheels. -
Cement
A cement is a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together. -
Morse telegraph
It worked by transmitting electrical signals over a wire laid between stations. -
Combustion engine
A combustion engine is an engine which generates mechanical power by combustion of a fuel. -
Dynamite
Dynamite is an explosive made of nitroglycerin, sorbents (such as powdered shells or clay) and stabilizers. -
Radio Tesla
La radio (entendida como radiofonía o radiodifusión, términos no estrictamente sinónimos)1 es un medio de comunicación que se basa en el envío de señales de audio a través de ondas de radio, si bien el término se usa también para otras formas de envío de audio a distancia como la radio por Internet. -
Telephone
A telephone is a telecommunications device that permits two or more users to conduct a conversation when they are too far apart to be heard directly. A telephone converts sound, typically and most efficiently the human voice, into electronic signals that are transmitted via cables and other communication channels to another telephone which reproduces the sound to the receiving user. -
X-ray
An X-ray, or X-radiation, is a penetrating form of high-energy electromagnetic radiation. -
First flight
The maiden flight, also known as first flight, of an aircraft is the first occasion on which an aircraft leaves the ground under its own power. -
Nuclear reactor
A nuclear reactor, formerly known as an atomic pile, is a device used to initiate and control a self-sustained nuclear chain reaction. -
New horizons spacecraft reaches pluto
New Horizons is an interplanetary space probe that was launched as a part of NASA's New Frontiers program
