The turbine invented by Charles Parsons powered ships. Assembled in numbers, they provided an efficient means of driving electrical generators and producing that most useful commodity. The second-prize essay, by george. Dowe, also of Washington,. C., who may have been a patent attorney, was more philosophical. He divided his inventions into those aiding three broad sectors: production, transportation and communication. Electrical fixation of atmospheric nitrogen.
What Are natural Fertilizers?
It appears on this list for only one reason: It is used to extract gold from ore. Gold is the belarus life blood of trade, and in 1913 it was considered to be the foundation for international commerce and national currencies. The nikola tesla induction motor. This epoch-making invention is mainly responsible for the present large and increasing use of electricity in the industries. Before people had electricity in their homes, the alternating currentproducing motor constructed by tesla supplied 90 percent of the electricity used by manufacturing. The linotype machine enabled publishers—largely newspapers—to compose text and print it much faster and cheaper. It was an mentality advance as large as the invention of the printing press itself was over the painstaking handwritten scrolls before. Pretty soon we wont be using paper for writing and reading, so the history of printing will be forgotten anyway. The electric welding process of Elihu Thomson. In the era of mass production, the electric welding process enabled faster production and construction of better, more intricate machines for that manufacturing process. The electric welder invented by Elihu Thomson enabled the cheaper production of intricate welded machinery.
The moving picture has transformed the amusements of the multitude. The technical pioneer he cited was Thomas Edison. For the realization of an age-long dream he gave the laurels of success to the Wright brothers, but apart from its military use reserved judgment on the utility of the invention: It presents the least commercial utility of all the inventions considered. Systems for transmitting information between people have been around for centuries, perhaps millennia. Telegraph signals got a speed boost in the. From Samuel Morse and Alfred vail. Wireless telegraphy as invented report by guglielmo marconi, later evolving into radio, set information free from wires.
The electric furnace also converted aluminum from a merely precious to very useful metal (by reducing its price 98 percent and was radically transforming the steel industry. The steam turbine, invented by Charles Parsons in 1884 and commercially introduced over flight the next 10 years. A huge improvement in powering ships, the more far-reaching use of this invention was to drive generators that produced electricity. Many inventors worked toward the goal of a self-propelled vehicle in the 19th century. Wyman gave the honor specifically to gottleib daimler for his 1889 engine, arguing: a century's insistent but unsuccessful endeavor to provide a practical self-propelled car proves that the success of any type that once answered requirements would be immediate. Such success did come with the advent of the daimler motor, and not before. Entertainment always will be important to people.
Following are excerpts from the first- and second-prize essays, along with a statistical tally of all the entries that were sent. The first-prize essay was written by william. Wyman, who worked in the. Patent Office in Washington,. C., and was thus well informed on the progress of inventions. His list was:. The electric furnace (1889) It was the only means for commercially producing Carborundum (the hardest of all manufactured substances).

A competition sponsored in 1913. Scientific American asked for essays on the how 10 greatest inventions. The rules: our time meant the previous quarter century, 1888 to 1913; the invention had to be patentable and was considered to date from its commercial introduction. Perception is at the heart of this question. Inventions are most salient when we can see the historical changes they cause.
In 2013 we might not appreciate the work of nikola tesla or Thomas Edison on a daily basis, as we are accustomed to electricity in all its forms, but we are very impressed by the societal changes caused by the Internet and the world Wide. A century from now they might be curious as to what all the fuss help was about. The answers from 1913 thus provide a snapshot of the perceptions of the time. The airplane: The Wright Flyer for military purposes, being demonstrated at Fort myer,., in 1908. Image: Scientific American - november 1, 1913.

Potassium sulfate and potassium nitrate are used on crops that are harmed by chlorides. The term straight fertilizer stands for any material that supplies one of the three principal macronutrients. The three macronutrients are nitrogen, phosphorus, and potassium. Mixed fertilizers are fertilizers that supply more than one macronutrient. This information is neccesary to one who is intrested in purchasing fertilizer. The fertilizer companies or manufacturers basically list every package or container with three numbers. For example a package that says 4-16-18, contains 4 percent nitrogen, 16 percent phosphoric oxide, and 18 percent potassium oxide.

nitrogen a year. This is eight times more than what farmers used in 1950. The most widely used fertilizer is pure ammonia. It is kept in liquid form under pressure in steel tanks. Three solid nitrogen fertilizers are ammonium sulfate, ammonium nitrate, and ammonium phosphate. Two common phosphorus fertilizers are superphosphate and triple superphosphate. Phosphorous fertilizer is made by treating phosphate rock with sulfuric acid.
There are two kinds of fertilizers. There is organic and inorganic. Organic fertilizers are bonemeal, fishmeal, blood, and farmyard manuer. Inorganic manuer is Nitrogen, potassium or any other element necessary in the aid of plant growth. If one accidently digests inorganic fertilizer, he or she must see a doctor as soon as possible. One can get sume red eyes, itchiness, and or stomach problems. During World War 2, the government built many factories to absorb nitrogen gas from the air and to use them in explosives.

More, fertilizers are substances added to the soil sprayed on leaves over of plants to help them grow better or in some cases faster. Plants need twenty essentail elements to help them grow. A plant needs nitrogen, phosphorus, potassium, calcium, sulfur, and magnesium the most to grow healthy. Most soils naturally contain enough trace elements for field crops, but such elements must be added when certain fruits and vegetable plants are grown. Nitrogen, phosphorus, and potassium are the top three elements needed in plant growth. Legumes are plants which absorb nitrogen gas from the air and bring the gas to the ground. Legumes are planted over with other crops and those plants get the required amount of nitrogen and grow healthy.
