Series and Parallel Resistors

This experiment demonstrates how current is distributed in resistors connected in series or parallel, and thus describes how to calculate the total "effective" resistance. Using Ohm's law, it possible to convert between the voltage and current through a resistance, if the resistance is known. For two resistors connected in series, (meaning that they are wired one after the other), the same current will flow through them. The voltages will add up to a "total voltage", and thus, the total "effective resistance" is the sum of the two resistances. This is sometimes called a "voltage divider" because the total voltage is divided between the two resistors in proportion to their individual resistances. For two resistors connected in parallel, (meaning that they are both wired between two shared terminals), the current is split between the two while they share the same voltage. In this case, the reciprocal of the total effective resistance will equal the sum of the reciprocals of the two resistances. Series and parallel resistors are a key component to most circuits and influence how electricity

Observational Research

If you want to know how someone thinks or feels, you can ask that person questions.  Another approach is to observe how the person is acting or look for indicators of how they acted in the past. While observations may seem revealing, it isn’t always easy to know if they are truly accurate. For instance, you may see a person smiling and assume they are happy, when in reality they are annoyed and merely being polite. The purpose of science is to move beyond an individual’s own views of the self because they are inherently skewed by that individual’s expectations, previous experience, personal biases, motivations, emotions, etc. While a person may have unique insight into one’s self, these insight may not accurately represent reality. Put more simply, what a person says, does not always match up well with what they actually do. For this reason, researchers should incorporate a variety of measures (e.g., asking participants to report how they feel, but also observing actual behavior) in order to more accurately capture how the person truly feels. This video demonstrates a correlational des

Cardiac Exam I: Inspection and Palpation

The cardiac assessment is one of the core examinations performed by almost every physician whenever encountering a patient. Disorders of the cardiac system are among the most common reasons for hospital admission, with conditions ranging from myocardial infarction to congestive heart failure. Learning a complete and thorough cardiac examination is therefore crucial for any practicing physician. If there is pathology in the heart or circulatory system, the consequences can also be manifested in other bodily areas, including the lungs, abdomen, and legs. Many physicians instinctively reach straight for their stethoscopes when performing cardiac exams. However, a large amount of information is gained before auscultation by going through the correct sequence of examination, starting with inspection and palpation.

Tree Identification: How To Use a Dichotomous Key

JoVE 10070

Source: Laboratories of Margaret Workman and Kimberly Frye - Depaul University

A dichotomous key is a tool that identifies items in nature, such as leaves. This method is based on the idea of choosing between two characteristics. The word dichotomous comes from two Greek words that mean “to divide into two parts.” In a dichotomous key for leaf identification, each pair of phrases describes different features of the leaf. Only one of the phrases correctly applies to the leaf being keyed out. The correct phrase leads to the next pair of phrases, or states the name of the tree from which the leaf came. Using a field guide to trees and the iTree National Tree Benefits Calculator helps to identify trees in a field investigation, which shows the significance of trees in terms of their environmental benefits, such as storm water management, increasing property value, energy efficiency, air quality, and carbon sequestration.

General Approach to the Physical Exam

The examination of the body is fundamental to the practice of medicine. Since the Roman Empire, physicians have described the connection between alterations in function of specific parts of the body and specific disease states and have sought to further scientific understanding to improve bedside diagnosis. However, in this modern age of increasing technology within medical diagnostics, it is important to consider the role that physical examination plays today. It is misguided to believe that physical examination holds all the answers, and much has been written about the questionable utility of certain maneuvers previously held in high regard. It is equally misguided to suggest that physical examination plays little role in the modern patient encounter. Physical examination remains a valuable diagnostic tool; there are many diagnoses that can only be made by physical examination. A diagnosis made by labs or imaging is rarely done in the absence of findings detectable at the bedside. As the provider conducts a history and physical, they are actively generating and testing hypotheses to explain the patient's condition. The information one gathers may not replace the need
