John Snow used a meticulous epidemiological approach to determine the source of water during the 1854 cholera outbreak in London. He mapped the locations of cholera cases and overlayed them with the locations of public water pumps. By identifying a cluster of cases near the Broad Street pump, he hypothesized that contaminated water from this source was responsible for the outbreak. His investigation ultimately led to the removal of the pump handle, significantly reducing cholera cases in the area.
What else can I help you with?
In a laboratory experiment John uses a mesh to separate soil particles from water. Which technique of separation is he using?
John is using the technique of filtration to separate soil particles from water. In this process, the mesh acts as a filter, allowing the liquid to pass through while retaining the solid particles. This method is commonly employed to separate mixtures based on particle size.
How did john snow vaccinate cholera?
John Snow did not invent the cholera vaccine; he was a pioneer in epidemiology and is best known for his work in identifying the source of a cholera outbreak in London in 1854 by linking it to contaminated water from a public pump on Broad Street. His findings helped establish the importance of clean water in preventing disease transmission.
Who proposed a given compound always has the same relative numbers and kinds of atoms?
The law of constant composition, proposed by Joseph Proust, states that a compound always has the same relative numbers and kinds of atoms regardless of its source or method of preparation. This law forms the basis of modern stoichiometry in chemistry.
Was john Dalton rich?
John Motgomery Dalton was not rich he was born in a poor family.
Was the scientific method used by John Dalton?
Yes, John Dalton used the scientific method in his work as a chemist and physicist. He conducted experiments, formulated hypotheses, tested his ideas through experiments, and revised his theories based on the results. This systematic approach helped him develop his atomic theory, which revolutionized the field of chemistry.
How did john snow help save lives?
Snow used epidemiological and statistical methods to identify the water pump in a district of London that was the source of cholera germs that had caused an outbreak of the disease. In doing this he helped to lead the way in applying similar approaches, even before the germ theory of disease had been developed. Please see the link.

By what method did Dr. John Snow discover that Soho's cholera victims were clustered around a pump?
Dr. John Snow discovered the clustering of cholera victims around the Broad Street pump through meticulous mapping and epidemiological investigation. He plotted cases of cholera on a map of Soho and noted a significant concentration of cases near the pump. By interviewing local residents, he found that many of the afflicted had used water from this specific pump. This evidence led him to conclude that contaminated water from the pump was the source of the cholera outbreak.
