Leonardo Da Vinci or Thomas Edison
Historians stipulate that it was Leonardo Da Vinci’s fascination with flight that inspired him to innovate the anemometer, an instrument for measuring the speed of wind.
One of Da Vinci’s most famous inventions, the flying machine (also known as the "ornithopter") ideally displays his powers of observation and imagination, as well as his enthusiasm for the potential of flight. The design for this invention is clearly inspired by the flight of winged animals, which da Vinci hoped to replicate. In fact, in his notes, he mentions bats, kites and birds as sources of inspiration.
Though the first actual helicopter wasn’t built until the 1940s, it is believed that Leonardo da Vinci’s sketches from the late fifteenth century were the predecessor to the modern day flying machine. As with many of da Vinci’s ideas, he never actually built and tested it – but his notes and drawings mapped out exactly how the device would operate.
Da Vinci made a sketch of the invention with this accompanying description: "If a man have a tent made of linen of which the apertures (openings) have all been stopped up, and it be twelve braccia (about 23 feet) across and twelve in depth, he will be able to throw himself down from any great height without suffering any injury.
The way Leonardo da Vinci saw it, the problem with the canons of the time was that they took far too long to load. His solution to that problem was to build multi-barreled guns that could be loaded and fired simultaneously.This idea forms the basis of war inventions like da Vinci’s 33-barreled organ, which featured 33 small-caliber guns connected together. The canons were divided into three rows of 11 guns each, all connected to a single revolving platform. Attached to the sides of the platform were large wheels.
The precursor to the modern tank, Leonardo Da Vinci’s armored car invention was capable of moving in any direction and was equipped with a large number of weapons. The most famous of da Vinci’s war machines, the armored car was designed to intimidate and scatter an opposing army.
This was one of the main ideas behind many of da Vinci’s war inventions – among them, his giant crossbow. Designed for pure intimidation, da Vinci’s crossbow was to measure 42 braccia (or 27 yards) across. The device would have six wheels (three on each side) for mobility, and the bow itself would be made of thin wood for flexibility.
Triple Barrel Canon:
As a military engineer, one of Leonardo da Vinci’s key beliefs was that mobility was crucial to victory on the battlefield. This idea is seen in many of his war inventions, from his mobile bridges and ladders to many of his weapon designs. A prime example is da Vinci’s triple barrel canon invention. During da Vinci’s time, canons were generally used at home in stationary positions rather than on the battlefield. This was because they were heavy and took a lot of time to reload. Da Vinci designed his triple barrel canon to solve both of these problems – a fast and light weapon that could do a lot of damage on the battlefield.
To put away any initial confusion – Leonardo da Vinci did not invent the clock. What he did was design a more accurate clock. While clocks that showed hours and minutes had become increasingly accurate in da Vinci’s time (the 15th century), they didn’t really make a big leap forward until the incorporation of the pendulum about 200 years later. But, da Vinci actually designed a more accurate clock in his lifetime.
Perhaps even more interesting than the ambition and innovation behind Leonardo da Vinci’s Colossus invention is the dramatic and heartbreaking story of his attempts to bring it to life. In 1482, the Duke of Milan commissioned da Vinci to build the largest horse statue in the world.
Perhaps no idea speaks to the epic ambition and scope of Leonardo da Vinci’s inventions better than his ideal city. This invention focuses not just on a single area but combines da Vinci’s talents as an artist, architect, engineer and inventor to create an entire city.
Da Vinci also incorporated these mechanisms into his self-propelled cart invention, which many people consider the very first robot. But da Vinci used the parts to create another robot too – his Robotic Knight. Though a full drawing of da Vinci’s robotic knight has never been recovered, fragments detailing different aspects of the knight have been found scattered throughout his notebooks.
Before motorized vehicles were even a glimmer in someone’s eye, Leonardo da Vinci designed a self-propelled cart capable of moving without being pushed. Among its other accomplishments, many consider da Vinci self-propelled cart invention to be the world’s first robot. The self-propelled cart was one of the many inventions that Leonardo created dealing with locomotion and transportation. Historians later deduced that da Vinci specifically designed the cart for theatrical use.
What made Leonardo da Vinci such a great artist was also what made him such a great inventor: his fascination with the world around him. This was the case with water. In his lifetime, da Vinci designed many inventions dealing with water – perhaps, most notably, scuba gear.
Designed for Duke Sforza, Leonardo da Vinci’s revolving bridge could be quickly packed up and transported for use by armies on the move to pass over bodies of water. The bridge would swing across a stream or moat and set down on the other side so that soldiers could pass with little trouble. The device had wheels and incorporated a rope-and-pulley system for both quick employment and easy transport. It was also equipped with a counterweight tank for balancing purposes."
Leonardo da vinci built the anemometer, flying machine, helicopter, parachute, 33-barreled organ, armoured, giant crossbow, triple barrel canon, clock, colossus, ideal city, robot knight, self propelled car, scuba gear, and the revolving bridge. They all help us today.
With his extensive work in telegraphy and the telephony Thomas Edison contributed greatly to mass communications. Telegraphy Automatic telegraphs transmit messages at higher speeds than those sent and received by Morse telegraph operators. In 1874, improving upon several of his previous inventions, Edison invents the quadruplex telegraph for Western Union, which transmits four messages simultaneously.
A crucial development in Edison’s career was the concept and implementation of electric-power generation and distribution to homes, businesses, and factories. After a year of research and tests, Edison conducts his first successful experiments with the light bulb in October 1879 using a carbon filament that would burn in a vacuum in a glass bulb for 40 hours.
Power System Edison knew that without a method to deliver electricity, his light bulb would be ineffective. He modeled his system after the gas systems of the time. Edison designed a system of conductors, meters, lamp fixtures, sockets, fuses and current-switches. Electric Generator In 1879 Edison’s research leads him to an important discovery in improving the design of generators. His invention led to generators that had more efficient power output than those in existence at the time.
motion Picture Camera:
Edison began working on motion pictures in the late 1880s. A member of his experimental staff, William Kennedy Laurie Dickson, played a key role in the development of the Kinetograph (a motion picture camera) and the Kinetoscope (motion picture viewer). In 1893, Edison demonstrates his system for making and showing motion pictures. In less than a decade, motion pictures become a popular and successful industry."
Edison was a very thoughtful man and made very outstanding invention including the camera, he created electricity, the phone and the phonograph and many more.
