Explanation:

1- Alexander Graham Bell was a British scientist, inventor and speech therapist, naturalized American. After a series of procedures (which would continue for years in the form of judicial claims), he obtained in 1876 the telephone patent in the United States.

2- The Wright brothers, Wilbur and Orville, were two aviators, engineers, inventors and pioneers of aviation, generally named together, and recognized worldwide as those who invented, built and flew the world's first airplane.

3- Thomas Alva Edison was the first to patent a carbon filament incandescent bulb, viable outside laboratories, that is, commercially viable. He patented on January 27, 1880.

4- Henry Ford developed an assembly line with a superior production capacity, of which his emblematic product was the Ford T.

5- Samuel Morse was an American inventor and painter who, together with his associate Alfred Vail, invented and installed a telegraphy system in the United States, the first of its kind. It was the Morse telegraph, which allowed messages to be transmitted by electrical pulses encrypted in the Morse code, also invented by him.

6- The Tom Thumb was the first American-built steam locomotive, created by Peter Cooper.

7- Robert Fulton was an American engineer, entrepreneur and inventor, known for developing the first steamboat, which he named Clermont.

8- Elias Howe was an American inventor, pioneer in the creation of the sewing machine.

9- Cyrus Hall McCormick was an American inventor and founder of the McCormick Harvesting Machine Company, which became part of the International Harvester Company in 1902. McCormick is considered the inventor of the automatic combine harvester and other agricultural machines.

10- Cotton Gin was developed by Eli Whitney in 1793. This small machine allowed the separation of cotton fibers and seeds at high speed and economically, being able to supply the growing demand for raw cotton after the invention of the loom.

in the united states, the president is controlled by the

constitution, and in all respects subordinate to it. insofar

as it deals with presidential power, however, the american

constitution has proved to be a highly malleable document.

with very few exceptions,' the constitutional provisions relating to the president have not been changed at all since

they were ratified in 1787. but in the late twentieth century, those provisions do not mean what they meant in

1787. the constitution is a legal document, and it is enforced judicially; but its meaning was hardly fixed when it

was ratified. in particular, the contemporary president has

far broader powers than the original constitution contemplated. it is remarkable but true that large-scale changes in

the authority of the president have been brought about

without changes in the constitutional text, but nevertheless

without significant illegality.

this is a paradox. is it not clear that constitutional

changes, if not textual, are illegal? the paradox has considerable relevance to our current thinking about the presidency in particular and about constitutionalism in general.

perhaps the framers of the american constitution feared

legislative power most of all; 2 but from well-known events

in the twentieth century, it is possible to conclude that it is

presidential power that holds out the greatest risks to both

liberty and democracy. the president is by far the most visible leader in the nation; he is often the only person in government with a national constituency. moreover, he is

in 1862, president lincoln's emancipation proclamation opened the door for african americans to enlist in the union army. although many had wanted to join the war effort earlier, they were prohibited from enlisting by a federal law dating back to 1792.
