Darwin, Curie, Einstein, Newton… These are names we all have heard at some point or another, but why? Throughout the ages, scientists like these have endeavored to find answers to the questions of the natural world and, in so doing, have helped advance science and technology to help create the modern world we live in today.

After you watch the video and read the article in learning block 5-3, consider what scientist and milestone scientific discovery helped pave the way for the natural-science topic you identified in your news story in Theme: Understanding the Scientific Process. Provide a response to the following questions in your initial post:

  • Identify the major historical scientific discovery that is the foundation for the natural science news story you have examined throughout the course. You may find the background information for this in the course materials in previous learning blocks. If you find that you need to conduct your own research, you can do so using the resources provided in Theme: Understanding the Scientific Process.
  • Provide a brief (2- to 3-sentence) summary of the scientist who made the historical scientific discovery you identified in the first question. Use examples from your news story to show how this historical scientific discovery impacts our world today.

When responding to your peers’ posts, consider how the work of the scientists they chose has influenced the modern world. Why does their research matter to us as individuals? Are there any connections to the natural-science topic you identified in your news article?

To complete this assignment, review the Discussion Rubric document.

The major historical scientific discovery that is the foundation for the natural science news story Injectable, flexible electrode could replace rigid nerve-stimulating implants is rooted in Robert Hooke’s discovery of the cell in 1655; which he (Leonardo Newtonic, 2018) discovered through his extensive work using microscopes. His discovery was a major breakthrough in the life science spectrum, and the study of biology. This one discovery paved the way for researchers in the field of Medicine to study cell make up, mutations, and variants that cause modern day diseases and genetic disorders. These advances rooted in biology led Hooke to define the cell theory that shows how all living organisms are made up of cells “the basic unit of life”. Once this discovery was made other scientist such as Louis Pasteur used this information as building block to his research on germs and vaccines.

Robert Hooke is also responsible for (Leonardo Newtonic, 2018) Hooke’s Law of Elasticity that proposes “that stretching of a solid body is proportional to the force applied to it” which supports todays research on the “injectrode” that is being developed by the University of Wisconsin-Madison (Science Daily, 2019). In their research they have found that “Typical implants are really stiff, and so as the body moves, they wear and tear and break down. Our liquid cures, and the result is much closer to the normal elasticity of tissue. You can actually stretch it and increase its size 150 to 200% without losing its conductivity.” This allows modern day scientist to place the “injetrode” and have it last longer and provide better conductivity based on elasticity.

Hello everyone,

The foundation and roots of the Voyager one and two programs starts with the beginning of the space race between the United States and the former Soviet Union. During the late 1880s and early 1900s, scientists made theories and dreamed about sending a satellite into low orbit.

The first artificial satellite sent into space was Sputnik 1 in 1957. The satellite was not created by one scientist, but a group of russian scientists lead by Mikhail Tikhonravov and launched by a intercontinental ballistic missle. Sputnik remained in orbit sending radio signals and sent data about the upper atmosphere until the satellite burned up in 1958.

Sputnik 1 impacted the world by teaching scientists how to track objects that are in orbit. This connects to the Voyager program as scientists are tracking the space probes location in interstellar space by using the same methods of data transmission.

Also, the fear of the Soviet success in the United States lead to much more spending and research taking place on space programs. Without this push and loss, the United States could been far behind in technology research and in the overall space race then the Soviets during this time period.
