How can you tell which star cluster is older?
How can you tell which star cluster is older? By determining the mass of the main-sequence turnoff stars, we get the age of the cluster. The cluster age equals the main-sequence lifetime of the turnoff stars. This is one of the ways we have studied the age of the Universe and the formation history of […]
How did alchemists contribute to science?
How did alchemists contribute to science? Through the span of several millennia, alchemists “were learning fundamental principles of chemistry: breaking down ores, dissolving metals with acids, and precipitating metals out of solution [8].” This laid the foundations of basic scientific experimentation with modern alchemists such as Boyle emphasizing the … What were some contributions of […]
