What happened during the Prohibition in Spain?
- The Spanish authorities enacted new rules and regulations in the late 1600s to limit the number of pulquerias, to allow for less storage rooms for extra pulque, and to completely eliminate seating.
- Did the shop owners protest?
- But these restrictions did not do much to reduce their popularity, and their patrons continued to frequent them.
- Was there any other controversy?
- Pulquerias and what they represented continued to be a major source of contention between the Spanish ruling class and the urban masses throughout the Bourbon period until Mexico gained independence in 1821.
- Are there any other interesting aspects about this article?
- The beginning of modern Mexico saw a decrease in the regulations imposed on pulquerias.
- Why did they loosen the regulations?
- This was because of the lack of strong central government in the newly independent state, as well as the political and economic advantages that local governors saw in this well-established institution.
- Did this cause any other problems?
- 
****
Next: The second half of the 19th century saw another jump in the number of pulquerias, especially in Mexico City, because of this lack of regulation and further urban growth.

What was Luke Winslow-King's music like in Prague?
- In the summer of 2003, Winslow-King spent the summer in the Czech Republic after he won an ambassador scholarship to study Czech music at Charles University in Prague.
- Are there any other interesting aspects about this article?
- During the fall of 2002 when he was 19 years old, after dropping out of college after a semester at Western Michigan University, Winslow-King went on a cross-country tour with musicians Seth Bernard and Daniel Kahn, playing Woody Guthrie songs in a show called "From California to the New York Island. " While making a stop in New Orleans, the band's car and instruments were stolen after being parked on Ursulines Street in the Tremé district.
- Was he ever a suspect in the theft?
- The theft meant Winslow-King had to spend time in New Orleans.
- Did he ever get injured in the theft?
- During the weeks he was there, when they got the van back, but no instruments, Winslow-King fell in love with the city, and in 2001 decided to permanently relocate to New Orleans.
- Did he find any instruments in New Orleans?
-

Next: He knew the soul singer John Boutté of the band ¡Cubanismo!

What is the cityscape of Berlin?
- Each of the national governments based in Berlin—the 1871 German Empire, the Weimar Republic, Nazi Germany, East Germany, and now the reunified Germany—initiated ambitious (re-) construction programs, with each adding its own distinctive style to the city's architecture.
- What is the most important fact in the article?
- Berlin was devastated by bombing raids during World War II, and many of the buildings that had remained after the war were demolished in the 1950s and 1960s, in both West and East Berlin.
- Why were they demolished?
- Much of this demolition was initiated by municipal architecture programs to build new residential or business quarters and main roads.
- Are there any other interesting aspects about this article?
- The eastern parts of Berlin have many "Plattenbauten", reminders of Eastern Bloc ambitions to create complete residential areas consisting of fixed ratios of shops, kindergartens, and schools to the number of residents.
- What is the tallest building in Berlin?
-

Next: The Fernsehturm (TV tower) at Alexanderplatz in Mitte is among the tallest structures in the European Union at .

what is the difference between newton's law and gauss's law
- If the density is ρ, the volume is V and g the standard gravity, then: The volume of this cuboid is equal to the area of the top or bottom, times the height — the formula for finding the volume of a cube.
- what is the difference between newton's law and gauss's law
- By balancing these forces, the total force on the fluid is This sum equals zero if the fluid's velocity is constant.
- what if the fluid moves
- Dividing by A, Or, P − P is a change in pressure, and h is the height of the volume element—a change in the distance above the ground.
- what if the fluid moves
- By saying these changes are infinitesimally small, the equation can be written in differential form.
- what if the fluid moves
-

assistant: Density changes with pressure, and gravity changes with height , so the equation would be: Note finally that this last equation can be derived by solving the three-dimensional Navier–Stokes equations for the equilibrium situation where Then the only non-trivial equation is the formula_11-equation, which now reads Thus, hydrostatic balance can be regarded as a particularly simple equilibrium solution of the Navier–Stokes equations.
