Foods to improve sex drive in males

Traffic and Safety Hood & Smoke Protector: invented The first Traffic Signal and The Gas Mask. The Morgan traffic signal was a T-shaped pole unit that featured three positions: Stop, Go and an all-directional stop position.
On July 25, 1916, Garrett Morgan made national news for using his gas mask to rescue 32 men trapped during an explosion in an underground tunnel 250 feet beneath Lake Erie. Le 25 juillet 1916, Garrett Morgan est a la une des journaux nationaux pour avoir utilise son masque a gaz pour sauver 32 personnes englouties au sous-sol apres une explosion dans un tunnel a 76 metres en dessous du niveau de mer sous le lac « Erie ». Lewis Latimer (1848–1928) invented an important part of the light bulb — the carbon filament. The Invention of the Carbon Filament, an important part which makes Thomas Edison Invention of the Light Bulb see the light.
Jan Ernst Matzeliger (1852–1889) invented a shoemaking machine that increased shoemaking speed by 900%. Born on the Caribbean island of Surinam, Jan Ernst Matzeliger came to the United States in 1871 at age 19. For centuries, the most difficult and time-consuming aspect of making shoes was connecting the sole to the main leather part of the shoe. Pendant des siecles, l'aspect le plus difficile et long dans la fabrication des chaussures fut de relier la semelle a la piece principale de la chaussure qui est le cuir.
Information Technology: invented multi Hyperball Computer Networks making the invention of modern Supercomputer and Internet possible.
This photo was taken in the year I morphed from being a mathematical physicist who creates new mathematics to a supercomputer scientist that performed the world’s fastest computations.
Il est difficile de dire qui a invente l'Internet car il y a eu beaucoup de mathematiciens et de scientifiques qui ont contribue a son developpement ; les ordinateurs envoyaient des signaux entre eux des les annees 1950.
George Washington Carver (1864–1943) discovered 200 uses for peanut and 100 more uses for other Plant Products.
Carver's system of crop rotation -- growing different plants each year on one plot of land -- helped revitalize poor soild. Carver's reputation is based on his research into and promotion of alternative crops to cotton, such as peanuts, soybeans and sweet potatoes, which also aided nutrition for farm families. Medicine: invented the Cataract Laserphaco Probe, a method of eye surgery for blind people to see. Patricia Bath's passionate dedication to the treatment and prevention of blindness led her to develop the Cataract Laserphaco Probe.
Technology: invented the electronic control devices for guided missiles, IBM computers, and the pacemaker.
Otis Boykin (1920–1982) invented the electronic control devices for guided missiles, IBM computers, and the pacemaker. Otis Boykin is best known for inventing an improved electrical resistor used in computers, radios, television sets and a variety of electronic devices. Sarah Breedlove McWilliams Walker, better known as Madame CJ Walker or Madame Walker, together with Marjorie Joyner revolutionized the hair care and cosmetics industry for African American women early in the 20th century.
Sarah Breedlove McWilliams Walker, better known as Madame CJ Walker or Madame Walker, together with Marjorie Joyner revolutionized the hair care and cosmetics industry for African American women early in the 20th century.Eventually, her products formed the basis of a thriving national corporation employing at one point over 3,000 people.
Sarah Breedlove McWilliams Walker, mieux connue comme Madame CJ Walker ou Madame Walker, ainsi que Marjorie Joyner ont revolutionne les soins capillaires et l'industrie cosmetique pour les femmes Africain-Americains tot au 20eme siecle.
Granville T Woods dedicated his life to developing a variety of inventions relating to the railroad industry.
Granville T Woods dedicated his life to developing a variety of inventions relating to the railroad industry.To some he was known as the "Black Edison, both great inventors of their time.
Born in Canada, raised in Michigan and trained in mechanical engineering in Scotland, McCoy got a job with the Michigan Central Railroad. So, you want the "real McCoy?" That means you want the "real thing," what you know to be of the highest quality, not an inferior imitation.Other inventors tried to copy McCoy's oil-dripping cup.
Cheikh Anta Diop (1923-1986) was an African historian who, in a series of studies, dramatically and controversially maintained that the scope of Africa's contribution to world civilization was considerably larger than heretofore acknowledged.Cheikh Anta Diop was born at the end of 1923 in Diourbel, Senegal, a city reknowned for spawning great Islamic philosophers and historians. The center of a storm of controversy, Diop nevertheless opened up new paths of exploration, gave a new generation redemptive faith in its roots, and presented, if nothing else, a poetic image of greatness. Summaries of Diop's work can be found in Claude Wauthier, The Literature and Thought of Modern Africa (1964; trans. An important selection from Diop's Nations, negres, et cultures, in which he accounts for the myths of Negro inferiority, can be found in Irving Leonard Markovitz, ed., African Politics and Society (1970). Multidisciplinary: He built a striking clock entirely from wood, published a Farmers' Almanac.
Benjamin Banneker died quietly on October 25, 1806, lying in a field looking at the stars through his telescope. George Washington may have been the father of the United States, but the United States can thank Benjamin Banneker for making the city that bears Washington's name. Benjamin Banneker was a self-educated scientist, astronomer, inventor, writer, and antislavery publicist.
George Washington pouvait avoir ete le pere des Etats-Unis, mais les Etats-Unis peuvent remercier Benjamin Banneker pour avoir fait de la ville Washington DC ce qu’elle est et portant son nom. Born in 1896 in Virginia's Blue Ridge Mountains, Hoyner moved ot Chicago to study cosmetology.
Before Marjorie Stewart Joyner, every day was basically a bad hair day for millions of women.
Chemistry: Techniques to detect Bacteria in Urine, Blood, Spinal Fluids, drinking water and Food.
Boykin improved the pacemaker and made everyday electronic devices, such as the television and computers, more efficient and affordable. After the rescue, Morgan's company received requests from fire departments around the country who wished to purchase the new masks.
Apres ce sauvetage, la societe de Morgan a recu des commandes pour son masque a gaz des diverses unites de sapeurs-pompiers des USA. Born in Chelsea, Massachusetts, in 1848, Latimer fought briefly in the Civil War before working as an errand boy for a law firm specializing in patents. But few people know that Edison's first bulbs, which relied on bamboo, only lasted for around 30 hours. Mais peu de personnes savent que les premieres ampoules de ce Thomas Edison fabriquees a base de de bambou pouvaient illuminer seulement qu’au maximum environ 30 heures de temps.
He eventually landed in Lynn, Massachusetts, at a factory for shoemaking -- an industry, and product, he would revolutionize in a matter of years. For ten years, he worked secretly on developing a machine to do this quickly and efficiently. Pendant dix annees, Matzeliger a travaille secretement sur la fabrication d’une machine pour faire accomplir ce travail rapidement et efficacement.En 1883, Matzeliger a brevete son invention, et a ameliore ladite machine periodiquement jusqu'a sa mort, a l'age de 37, en 1889.
There were many mathematicians and scientists who contributed to its development; computers were sending signals to each other as early as the 1950s. This is an excerpt from an old memo I forwarded to a physicist explaining how to create new mathematics called partial differential equations from the wind velocities in the Earth’s atmosphere. But this was just the start, as Carver invented or bettered dozens of produts including adhesives, bleach, buttermilk, cheese, ink, chili sauce, linoleum, mayonnaise, shampoo, shoe polish, shaving cream and 300 (Three Hundred) uses for Peanut. At Tuskegee Carver developed his crop rotation method, which revolutionized southern agriculture.
The probe patented in 1988, was designed to use the power of a laser to quickly and painlessly vaporize cataracts from patients' eyes, replacing the more common method of using a grinding, drill-like device to remove the afflictions.
Her Walker System, which included a broad offering of cosmetics, licensed Walker Agents, and Walker Schools offered meaningful employment and personal growth to thousands of Black women. Par la suite, les produits de CJ Walker ont forme la base d'une societe nationale prospere utilisant a un moment donne plus de 3.000 personnes.

Granville T Woods invented more than a dozen devices to improve electric railway cars and many more for controlling the flow of electricity. He was responsible for oiling the moving parts of a train when it stopped, a dangerous task in the days before the telegraph allowed engineers to know whether or not a train was approaching. Philosopher, linguist, Egyptologist, mathematician, and scientist, one of the most profoundly revolutionary thinkers francophone Africa has produced in the 20th c.
Nations around the world mourned his passing, viewing him as a genius and the United States' first great Black Inventor. He built a striking clock entirely from wood, published a Farmers' Almanac, and actively campaigned against slavery.
Banneker etait un scientifique autodidacte, un astronome, un inventeur, un auteur, et un publiciste antiesclavagiste. Her design and patent for a "permanent wave machine" -- a mechanism that set hair in place for days, weeks, sometimes months -- changed cosmetology forever.Born in 1896 in Virginia's Blue Ridge Mountains, Hoyner moved ot Chicago to study cosmetology. Chappelle, the recipient of 14 patents,a member of the National Inventor’s Hall of Fame and many of whose discoveries are used in the fields of medicine, philanthropy, food science and astrochemistry was born in 1925 in Phoenix, Arizona. He attended Fisk College in Nashville, Tenn., and continued his education at the Illinois Institute of Technology in Chicago. Resistors slow the flow of electricity, allowing a safe amount of electricity to move through a device. Le masque a gaz de Morgan fut plus tard perfectionne pour usage de l'armee des USA Pendant la 1ere Guerre Mondiale. His skills were quickly recognized and Latimer was soon working with some to the world's most renowned inventors.
Long-lasting bulbs, using carbon filaments, were the brainchild of African-American inventor Lewis Latimer and his partner Joseph V. Les ampoules qui peuvent illuminer longtemps, telles que nous les connaissons de nos jours et utilisant des filaments de carbone, furent l'invention de l'inventeur Africain-Americain Lewis Latimer avec le co-inventeur ou associe Joseph V. In 1883, Matzeliger patented his invention, improving on it periodically until his death, at age 37, in 1889.
Sa nouvelle machine a permis de hausser la production des chaussures passant de 300 a 1400% d’unites sur la meme periode de fabrication, ce qui permis de faire chuter les prix de 50% et doubler le salaires des travailleurs dans l'industrie de chaussure.
But the Web owes much of its existence to Philip Emeagwali, a math whiz who came up with the formula for allowing a large number of computers to communicate at once.At Michigan, he participated in the scientific community's debate on how to simulate the detection of oil reservoirs using a supercomputer.
Philip Emeagwali, un celebre mathematicien qui a propose la formule pour permettre a un grand nombre d'ordinateurs de communiquer simultanement. He educated the farmers to alternate the soil-depleting cotton crops with soil-enriching crops such as; peanuts, peas, soybeans, sweet potato, and pecans.
With another invention, Bath was able to restore sight to people who had been blind for over 30 years. Otis Boykin also invented a variable resistor used in guided missile parts, a control unit for heart stimulators, a burglar-proof cash register and a chemical air filter.
Madame Walker’s aggressive marketing strategy combined with relentless ambition led her to be labeled as the first known African-American woman to become a self-made millionaire.An employee of Madame CJ Walker’s empire, Marjorie Joyner invented an improved permanent wave machine. His most noted invention was a system for letting the engineer of a train know how close his train was to others. In 1966 at Dakar the World Festival of Negro Arts honored Diop as "the black intellectual who has exercised the most fruitful influence in the twentieth century." In 1981, Diop's Civilisation Ou Barbarie ("Civilization or Barbarism") appeared. He was one of the first African Americans to gain distinction in science.Benjamin Banneker was educated by Quakers, however, most of his education was self-taught. Il a construit une horloge pendante entierement en bois, a publie un almanach des agriculteurs, et a activement fait campagne contre l'esclavage. In 1959, he patented a "wire precision resistor," which allowed specific amounts of electrical currents to flow for a specific purpose. Apres le constat d'une collision entre une automobile et un chariot hippomobile, Garrett Morgan s’est lance a nouveau dans la recherche pour inventer les feux-rouges. Nichols.Latimer a aide Alexander Graham Bell a faire les esquisses des modeles pour le telephone, ce qui lui permis d’obtenir le brevet d’invention pour avoir depose sa demande quelques heures avant ses concurrents. His new machine increased the amount of shoes that could be produced in a set period from 300 to 1400 percent, while helping to drop shoe prices by 50 percent and doubling the wages of those working in the shoe industry. Growing up in an oil-rich nation and understanding how oil is drilled, Emeagwali decided to use this problem as the subject of his doctoral dissertation. A Michigan, il a participe au debat de la communaute des scientifiques sur la simulation pour la detection des gisements de petrole en utilisant un super ordinateur. He wanted poor farmers to grow alternative crops both as a source of their own food and as a source of other products to improve their quality of life. This device patented in 1928, curled or "permed" women’s hair for a relatively lengthy period of time.
La strategie marketing agressive de Madame Walker's combinee avec l'ambition implacable a rendu possible a faire d’elle la premiere femme Africaine-Americaine connue pour avoir fait fortune et meme a devenir millionnaire. This device helped cut down accidents and collisions between trains.In 1888, Granville T Woods developed a system for overhead electric conducting lines for railroads, which aided in the development of the overhead railroad system found in cities such as Chicago, St. His first doctoral thesis, rejected by the Sorbonne, was published in 1954 under the title Nations negres et culture. Il fut l'un des premiers Africain-Americains a avoir gagne une mention distinguee en science. Walker, the inventor of several hair care products including the straightening comb.Hoping to find a way to ensure that a woman's hair looked fresh and vibrant the days after it was cut, Joyner created a dome-like device that sent electrical current to sections of the hair, thus setting it in place for extended periods of time. Soon after, he created a new resistor that could withstand shifts in temperature and air pressure. Il etait l’un des premiers a faire la demande et a acquerir un brevet d’invention aux USA pour lesdits feux-rouges. Latimer helped Alexander Graham Bell draft the blueprints for the telephone, securing the patent hours before a rival inventor. Il a rejoint plus tard l'equipe d'Edison, ou lui et son associe Nichols ont perfectionne l'invention d'Edison et ont brevete l'ampoule incandescente avec des filaments de carbone (et un procede pour leur fabrication) en 1891.Tout en travaillant dans le bureau de « Crosby & Gould », Lewis commenca l'etude de dessin et devint par la suite le chef d’equipe. Borrowing an idea from a science fiction story about predicting the weather, Emeagwali decided that rather than using 8 expensive Supercomputers he would employ thousands of microprocessors to do the computation.The only step left was to find 8 machines and connect them. Originaire d’une nation (Nigeria) riche en petrole et comprenant le systeme de forage du petrole bruit, Emeagwali a decide de faire du probleme sa these de doctorat. The most popular of his 44 practical bulletins for farmers contained 105 food recipes using peanuts.[4] He also developed and promoted about 100 products made from peanuts that were useful for the house and farm, including cosmetics, dyes, paints, plastics, gasoline, and nitroglycerin. The wave machine was popular among women white and black allowing for longer-lasting wavy hair styles. Une employee de l'empire de Madame CJ Walker, Marjorie Joyner a invente une machine et l’a amelioree en permanence.
His invention made trains safer and oiling the engines easier, improved the efficiency of America's entire transportation system.
Two later theses finally resulted in Diop being awarded a doctorat d'etat.Diop, however, left his mark in the realm of the reassessment of the role of black people in world history and culture. Benjamin Banneker a ete instruit par « Quakers », cependant, pour la majeure partie de son education il fut autodidacte. In 1926, she became the first African-American woman to receive a patent for her invention. Later, he developed techniques that are still widely used for the detection of bacteria in urine, blood, spinal fluids, drinking water and foods. It was a huge breakthrough that allowed many electronic devices to be made more cheaply and more reliably than ever before.
He later joined Edison's team, where he and Nichols improved on Edison's invention and patented the incandescent light bulb with carbon filaments (and a process for manufacturing them) in 1891. A « Crosby & Gould », Latimer, en passant des longues nuits avec le futur inventeur, a fait les esquisses des dessins pour la demande du brevet d’invention pour le telephone qui valurent ledit brevet d’invention a Alexander Graham Bell.

Empruntant une idee de la science-fiction sur la prediction de la meteo, Emeagwali a decide d’utiliser des milliers de microprocesseurs moins chers pour faire le calcul au lieu d’utiliser 8 super ordinateurs a des prix excessivement eleves.La seule etape qui restait a faire etait de trouver 8 ordinateurs interconnectes.
He received numerous honors for his work, including the Spingarn Medal of the NAACP.During the Reconstruction-era South, monoculture of cotton depleted the soil in many areas. Joyner went on to become a prominent figure in Madame CJ Walker’s industry, though she never profited directly from her invention, the assigned intellectual property of the Walker Company.
Ce dispositif brevete en 1928, permet de boucler les cheveux des femmes pendant une periode relativement longue contrairement aux procedes precedents. The noted African American inventor, Elijah McCoy was issued more than 57 patents for his inventions during his lifetime. Combining an unusual breadth of knowledge - including linguistics, history, anthropology, chemistry, and physics - he uncovered fresh evidence about the ancient origins and common principles of classical African civilization.
Shortly before his death, he spoke of devoting the rest of his life to a master plan that would preserve Africa for Africans. Twenty years later, Banneker began making astronomical calculations that enabled him to successfully forecast a 1789 solar eclipse. Il a tres tot revele au monde ses capacites d’inventions innees et a obtenu les toutes premieres acclamations nationales pour son travail scientifique sur l'enquete de 1791 relatif au territoire federal (maintenant Washington, D.C). In 1977, Chappelle turned his research efforts toward the remote sensing of vegetation health through laser-induced fluorescence (LIF).
Boykin's resistors were used in products from televisions and IBM computers to military missiles.
While working in the office Of Crosby & Gould, Lewis began the study of drafting and eventually became their head draftsmen.
Ce dernier a pu ainsi soumettre sa demande de brevet d’invention au bureau tutelle quelques heures seulement avant celles des concurrents et a ainsi obtenu les proprietes industrielles du telephone qu’avec l'aide de Latimer.Hiram S. In the early 20th century, the boll weevil destroyed much of the cotton crop, and planters and farm workers suffered. La machine a vague qui etait populaire parmi des femmes Europeenne-Americaine et Africaine-Americaine permet de maintenir les coiffures onduleuses plus durables.
His best known invention was a cup that fed lubricating oil to machine bearings through a small bore tube. He believed that people who feel they possess no past of their own tend to be absorbed and assimilated into the governing system, and are made to feel inferior because of this apparent deficiency. En 1753, il a construit une des premieres montres faites aux USA, une montre de poche en bois. Working with scientists at the Beltsville Agricultural Research Center, he advanced the development of LIF as a sensitive means of detecting plant stress.In 2007, the National Inventor’s Hall of Fame recognized Emmett Chappelle’s work with Lyophilized Reaction Mixtures. Boykin also famously invented a control unit for the pacemaker, a device implanted in the body to help the heart beat normally. During his employment with Crosby & Gould, Latimer drafted the patent drawings for Alexander Graham Bell's patent application for the telephone, spending long nights with the inventor. In 1987, he applied for and was given permission to use the machine, and remotely from his Ann Arbor, Michigan, location he set the parameters and ran his program. Carver's work on peanuts was intended to provide an alternative crop.America's economy was heavily dependent upon agriculture during this era making Carver's achievements very significant. Joyner a continue pour devenir une figure importante dans l'industrie de Madame CJ Walker, bien qu'elle n'ait jamais profite directement de son invention, la propriete intellectuelle etant conferee a la societe CJ. In fact, Diop prouved that African culture and history was older than any other, and influenced the course of other cultures more than usually given credit.Diop's argumentative thesis stressed the great contributions of Egypt, in particular, to the origins of culture and science, and asserted that Egyptian civilization was of black origin, a theory that has since been corroborated with anthropological evidence. Vingt ans apres, Banneker a commence a effectuer des calculs astronomiques qui lui ont permis de prevoir avec succes une eclipse solaire en 1789. This work revealed that a specific combination of chemicals caused all living organisms to emit light.
Bell rushed his patent application to the patent office mere hours ahead of the competition and won the patent rights to the telephone with the help of Latimer.Hiram S. Electric Light of Bridgeport, CN, et inventeur de la « Maxim machine gun ») a engage Lewis Latimer comme assistant manager. Decades of growing only cotton and tobacco had depleted the soils of the southern area of the United States of America. In 1887, he patented the Synchronous Multiplex Railway Telegraph, which allowed communications between train stations from moving trains.
Diop also challenged the prevailing view that the flow of cultural influence was from the north, the European or "Hamitic" areas, southward to the more primitive areas. When architect Pierre L'Enfant left the project (with all his plans) in a huff, Banneker managed to recreate the complete layout from memory. Ses calculs faits bien avant l'avenement celeste ont permis de contredire les previsions des mathematiciens et astronomes les plus celebres.
Chappelle’s discovery facilitated important findings within the fields of biology and chemistry including the development of methods of testing still widely used to detect bacteria in urine, blood, spinal fluids, water and even food.His work for the Research Institute in Baltimore, a division of Martin Marietta Corporation, an airplane and spacecraft manufacturer, helped to create a safe food supply for astronauts. Le talent de Latimer pour les esquisses et son genie creatif ont permis a cet inventer de mettre sur pied un procede pour la fabrication des filaments de carbone pour les ampoules a incandescence electrique de longue duree.
Within a few years, the oil industry had seized upon this idea, then called the Hyperball International Network creating a virtual world wide web of ultrafast digital communication. The economy of the farming south had been devastated by years of civil war and the fact that the cotton and tobacco plantations could no longer (ab)use slave labor. Granville T Woods' invention made it possible for trains to communicate with the station and with other trains so they knew exactly where they were at all times.Alexander Graham Bell's company purchased the rights to Granville T Woods' telegraphony patent enabling him to become a full-time inventor.
In the mid 1960's he also assisted in the development of instruments used in soil gathering on NASA’s Viking probe mission. Electric Light Company of Bridgeport, CN, and the inventor of the Maxim machine gun) hired Lewis Latimer as an assistant manager and draftsman.
En 1881, il a dirige l'installation des lumieres electriques a New York, a Philadelphie, a Montreal, et a Londres. Carver convinced the southern farmers to follow his suggestions and helped the region to recover. Among his other top inventions were a steam boiler furnace and an automatic air brake used to slow or stop trains. Some of his most recent work involves the use of fluorescence as a method for determining the health of forest vegetation. Latimer's talent for drafting and his creative genius led him to invent a method of making carbon filaments for the Maxim electric incandescent lamp.
Lewis Latimer etait le dessinateur original pour Thomas Edison (ou il a commence a travailler en 1884) et fut par consequent l’etoile brillante du succes de Thomas Edison.Lewis Latimer etait le seul Africain-Americain membre de vingt-quatre conseillers principaux de la division d'ingenierie de la Compagnie de Thomas Edison. Lorsque l’architecte Pierre L'enfant, dans une grande colere, a quitte le projet (avec tous ses plans), Banneker a pu se souvenir la planification complete et permis ainsi la poursuite des travaux de construction de Washington D.C.
This technique has two significant advantages: First it is nonintrusive and can be used with living plants. In 1881, he supervised the installation of the electric lights in New York, Philadelphia, Montreal, and London.Lewis Latimer was the original draftsman for Thomas Edison (who he started working for in 1884) and as such was the star witness in Edison's infringement suits.
Latimer fut egalement co-auteur d’un livre sur l'electricite editee en 1890 appelee, « eclairage electrique incandescent : Une description pratique d'Edison System.
Second, it can be performed from within a low-flying airplane, allowing researchers to monitor remote areas.While Emmett Chappelle made many significant contributions with his work, he is also well known throughout the scientific field for his work as a mentor. Lewis Latimer was the only African American member of the twenty-four "Edison Principles", Thomas Edison's engineering division of the Edison Company.
