To solve the stability problem, Bohr modified the Rutherford model by making sure that the electrons move in orbits of specific size and energy. The energy of an electron depends on the size of the orbit and is lower for smaller orbits. However, radiation can only happen when the electron jumps from one orbit to another.
This excerpt outlines the important precedent set by the court case Plessy vs. Ferguson. Plessy vs. Ferguson establishes the idea that "separate but equal" facilities are constitutional (aka legal). Essentially, this Supreme Court ruling allows for private and public places to be segregated. The ruling of Plessy vs. Ferguson resulted in segregated facilities all over the country including schools, restauraunts, bus stops, bathrooms, water fountains, etc.
This case is not overturned until 1954, in which the case Brown vs. Board reverses this idea and declares that separate but equal facilities violates the 14th amednment rights of African-American citizens.
