Describe how scientists have utilized indirect forms of measure to
overcome these challenges. 2. Choose two (2) of the most historically
influential tools or techniques in the physical sciences. Explain how
these techniques or tools work, and how they helped to advance our
understanding of the physical sciences. Part 2: Procedures in the
Physical Sciences: A Survey of Safety 3. Choose one (1) hazard
associated with research in the physical sciences. Discuss how
protective gear or equipment might be used to mitigate the hazard, as
well as its efficacy. 4. Describe the ways in which advancements in

Here’s a snippet of the essay.

 

Science is the systematic knowledge of phenomena in the world through observation and experimentation. It is the ongoing search for knowledge and understanding of the universe. Scientists require a variety of tools and techniques to measure and analyze phenomena in order to gain a better understanding of the universe. Direct measurement of phenomena is used for this purpose but there are times when it cannot be used thus requiring other indirect methods to achieve the purpose.

 

The determination of precise distances presents one of the major challenges to making direct measurements. Scientists analyze a variety of phenomena in order to understand why things are the way they are. A phenomenon such as an object in space proves difficult for scientists to measure their distance with precision. The size of a star cannot be converted into its real radiated power without the knowledge of its precise distance. The determination of precise distance enables the understanding of a variety of phenomena thus the inability to determine is a major challenge for scientists (Warren, 2003).

 

Scientists also experience challenges in direct measurement of the wave function because of Heisenberg’s uncertainty principle. The wave function is central to quantum theory and refers to the complex distribution used to effectively describe a quantum system. As a result of Heisenberg’s uncertainty principle, measuring and determining the wave function of a quantum system before it gets destroyed seems impossible (Lundeen et al., 2011).

 

Earthquakes are also part of the challenges scientists face when making direct measurements. The shifting of the Earth’s tectonic plates along its fault lines causes earthquakes. Direct measurement methods prove difficult because fault lines are many kilometers below the earth’s surface (Lee, 2002).
