What did sir isaac newton contribute to scientific thinking and knowledge

the underground railroad (apocope of the metropolitan railroad) is a system of urban trains located within a city and its metropolitan area. it is characterized for being a massive transport of passengers in the big cities, uniting diverse zones and their environs, with high capacity and frequency and in segregated form to other systems of transport. metropolitan railroads are built underground or on the surface, although most systems use mixed models where sections are combined in both modalities.

1 - as a result, the metro tends to reduce car travel for two reasons: first, due to the greater transfer of users from the car and, second, due to the reduction in the acquisition of cars in homes located in sectors near the stations of the metro.

2 -the metro allows to contribute effectively to the achievement of all the objectives of an urban development policy: it improves the efficiency of the city's economy by reducing travel costs and also generates a higher level of activities in the city center, taking advantage of of the agglomeration economies.

3 -it is a clean means of transport, since it uses renewable energy (usually electricity), taking care of the environment and avoiding excessive pollution.

1- in bradbury's  fahrenheit 451, all books are banned and burned upon discovery. in the nazi germany, books considered to be subversive to the regime would be burned to keep the population from generating ideologies that could challenge nazism.

2- was bradbury correct in his literal interpretation of  “where they burn books, they will also ultimately burn people.”? in some way, yes. when knowledge is not only limited, but also controlled, the people tied to it are led to their demise. just like in the novel, people in nazi germany who owned  subversive books were punished not only by the burning of their property, but also by the discrimination that followed after such a public form of consequence. if a person was seen being confiscated  subversive  books, they may be considered as an ally to the jews, which meant pretty much the same as being the enemy back then. because of the extreme exclusion and suffering that followed this punishment, it's almost like dying a slow death.

in this way, the phrase  “where they burn books, they will also ultimately burn people.” is both literal and figurative.
