Robert Goddard
Robert Hutchins Goddard (October 5th, 1882 - August 10th, 1945), is a Engineer and Physicien. He developed in first half of the 20th century one of the first prototypes of rocket S.
Biography
Youth
Robert Goddard is born the October 5th 1882 with Worcester in the state from the Massachusetts. De Nahum Danford Goddard (1859-1928) and Fannie Louise Hoyt (1864-1920). Robert is their only son. With time or the electricity made its beginnings in the cities of the the United States, the Goddard young person is interested in the Sciences. His/her father shows him how to produce static electricity on the rug of the living room, this experiment stimulates the imagination of the five year old boy.
Goddard is interested in the flights, initially the kites, then the balloons. It applies already to documenting very well its work and its experiments, a quality which will be very useful for him throughout its carrière.
These various interests, converge towards 1898, when built Goddard, at his place, a balloon with a frame of Aluminum. Five weeks later, after a methodical work and documented well it gives up the project. This failure at all does not affect however the determination and confidence that Goddard has already opposite its work.
In this same time, it is interested more and more in the space, after the reading of the famous novels of science fiction “the war of the worlds” of H.G. Weels. He even tells him as this Epiphany came to him on October 19th, when he worked with the pruning of a cherry tree. A thought crosses the spirit then to him: “It would not be marvellous, to be able to manufacture an apparatus which can go on Mars, I imagine it here in this valley with small scales.” Until the end of its life, it will commemorate this date, birthday of its greater inspiration.
Studies and beginning of career
Goddard had a fragile health; health issues related to its stomach made so that it takes two years of delay on his classmates. He becomes a voracious reader, and frequently visits the public libraries to borrow several books from it on physical sciences. Later, it continues its studies and with old 18 years, it makes its tenth school year at the secondary school of Worcester. Its pars then elected it twice president of its class. In 1904 with its school graduation it gives the speech of end of class, this privilege being granted to that, having obtained best the notes. It is at the time of this speech that he pronounces the sentence which will become its policy for the remainder of its life: “It was often proven that the dreams of yesterday, are the hope of today and the reality of tomorrow.” Goddard is engaged in 1904, at the Polytechnic Institute of Worcester. A. Wilmer Duff, the director of the department of physique notices it immediately, for his appetite of knowledge. Professor Duff, takes it under his supervision, Goddard becomes his assistant of laboratory.
He continues his social activities with Worcester. He joint fraternity Sigma Alpha Epsilon, and begins a long frequentation with Miriam Olsmstead, a coed of his secondary school. This frequentation however finished towards 1909.
Before its baccalaureat, he writes an article on a method of balance of the airplanes, the review “Scientific American”, publishes it in 1907. Goddard will write later in its personal newspaper, which he believed that this article was the first proposal on the ways of balancing a plane in vol. This proposal, arrives at the same moment as some bored scientific on the development of the functionalities of the gyroscope.
Goddard obtain its baccalaureat in physics of the Institute of Polytechnic of Wocester in 1908, with the autumn of the same year it is engaged at the Clark University.
Its first writings on the liquid propulsion of the rockets arrive in February 1909. Goddard, at this time had studied the possibilities of increasing the energy efficiency of fused, by using an alternative method with the conventional method of time i.e., fused using the powder.
Goddard receives a Control in Art of the Clark University in 1910, then it supplements there a Doctorate in Physics in 1911. It receives a purse in 1912 and works during still a year at the university before passing to the University of Princeton to work there thanks to another grant.
First Patents
The radio operator with the beginning of the year 1900 was a technology in emergence, a fertile field of activity to exploration and the innovation. In 1911 while it was at the Clark University, Goddard with studied the effects of the radio waves on the insulators. In order to produce a power able to produce a radio wave, he invented a vacuum tube, which reacted like a cathode-ray tube. Patent U.S. emitted No 1,159,209 on November 2nd, 1915. It was the first use of such a tube in order to amplify a signal, preceding that of Lee De Forest. This fact, signal the beginning of the electronic era.
At the beginning of 1913, Goddard is reached of a serious disease, tuberculosis, it thus gives up its work with Princeton. It turns over to Worcester, where it begins a long convalescence.
The years 1910
The attack of extreme altitudes
November 1st 1923, it makes function the first room with combustion with liquids in the center of experiments of Worcester. The April 19th 1932, the first rocket stabilized by Gyroscope and shutters rises towards the sky with stability and elegance.
The August 10th 1945, Robert Goddard dies at the 63 years age having largely contributed to the development of the rocket with liquid propulsion.
Criticisms
In 1919 it publishes off has Method Reaching Extreme Altitudes , in which it exposes the result of its theoretical analyzes and its tests of rockets. This book involves an important number of articles in the press. In the NewYork Times, the leading article of the January 13rd 1920 is particularly sarcastic:
- “Professor Goddard (...) does not know the relation the action and the reaction and the need for having something of more consistent than the vacuum against which to rest. Actually it seems only it to miss taught knowledge the every day with the college. ” (“Professor Goddard (...) does not know the relation between action and reaction and the need to cuts something better than has vacuum against which to react. Off race He only seems to lack the knowledge ladled out daily in high schools”)
Goddard made publish the year following an article named That Moon Rocket Proposition: Refutation off Nap Popular Fallacies or it pointed out some rudiments of mechanical Newtonnienne. It also organized a public demonstration while making function a model in a vacuum bell-jar. Its conclusion would have been: “So much for The NewYork Times”.
The newspaper retracted only the July 17th 1969, that is to say twelve years after the shooting of Sputnik:
- “It is now certain as a rocket can function as well in the vacuum as in the atmosphere. Times regrets its error. ” (“It is now definitely established that has rocket edge function in has vacuum ace well ace in year atmosphere. The Times regrets the error. ”)
