Math is an important aspect of numerous fields of study. However, in the STEM field, it is essential to the interpretation of various aspects of the sciences and their integration into everyday life. As a pre-medicine student, calculus is a crucial aspect of any STEM field but especially in the subfield of medicine. Although there are many uses for math in medicine, statistics is more common than calculus. This is due to the need for analyzing drug trial results and percentages of certain materials in the human body. Despite its usefulness, there are some downfalls. The Body Mass Index or BMI scale is one form of outdated mathematical testing in medicine. This is due to its inability to take into account muscle mass or water weight. Therefore, BMI testing deems numerous healthy individuals overweight simply for their body composition. Even though statistics takes prominence in the medical field, calculus is still a crucial aspect of many processes within it. One of these in particular is the calculation of drug concentration in one's system. This is done by determining the metabolic rate during drug trials and incorporating simple calculus to determine key information such as dosage amounts and the time intervals between them. However, in medicine, both statistics and calculus must work together to provide the results needed for providing healthcare. Another specific area of STEM in which calculus is crucial is aeronautics and space exploration. To determine whether or not a rocket will be successful, one must map out its arc. This also allows the scientists to implement factors such as speed and different types of resistance. This helps decide the materials used to construct these spacecraft as well as estimate how long the journey will take. The size of the spacecraft is dependent entirely on various factors such as the availability of the building material, estimated weight, and internal space necessary for the storage of key aspects of life such as breathable air and water. However, not all flights contain live organisms on board the spacecraft. For these automated flights, a path must be predetermined since the machinery does not have the autonomy needed to make judgment calls. Additionally, the assigned task of the spacecraft will determine its design and construction. If the vessel is lighter, then it will require less fuel to take off and maintain speed. This is all determined by calculus and therefore proves why it is essential to multiple different disciplines in the overarching field of STEM.
