The well-known historical development of Electromagnetism, strongly influenced by the work of Faraday and Maxwell, has led to the introduction of the magnetic field as an important component to explain the diverse phenomena of electromagnetic induction. This historical development is compared in the form of a thought experiment with a possible…

Quadcopters (also known as "drones") do not fly in vacuum. This is obvious enough that experimenting on one in a vacuum chamber would seem rather uninteresting, but there is one question that may be usefully addressed by such an experiment: the mechanism for yaw control. Quadcopters control yaw (rotation about the vertical axis) by…

This paper provides a brief introduction to antimatter and how it, along with other modern physics topics, is utilized in positron emission tomography (PET) scans. It further describes a hands-on activity for students to help them gain an understanding of how PET scans assist in detecting cancer. Modern physics topics provide an exciting way to…

Science learning for undergraduate students requires grasping a great number of theoretical concepts in a rather short time. In our experience, this is especially difficult when students are required to simultaneously use abstract concepts, mathematical reasoning, and graphical analysis, such as occurs when learning about RC circuits. We present a…

Our motivation for this article is for students to realize that opportunities for discovery are all around them. Discoveries that can still puzzle present day researchers. Here we explore an observation by a middle school student concerning the production of what appears to be water-like "ripples" produced in aluminum foil when placed…

A central goal of physics education is to teach problem-solving competency, but the description of the nature of this competency is somewhat fragmentary and implicit in the literature. The present article uses recent historical scholarship on Arnold Sommerfeld and Enrico Fermi to identify and characterize two positions on the nature of physics…

Physics is often seen as an excellent introduction to science because it allows students to learn not only the laws governing the world around them, but also, through the problems students solve, a way of thinking which is conducive to solving problems outside of physics and even outside of science. In this article, we contest this latter idea and…

In this article a new authorial EduPython application is presented. It is an online tool that supports the teaching of physics using a problem-solving method. It gives the teacher an opportunity to collect data that students send using their smartphones. The application uses the data to produce a collective answer of all the students which gives…

The sensors in modern smartphones are a promising and cost-effective tool for experimentation in physics education, but many experiments face practical problems. Often the phone is inaccessible during the experiment and the data usually needs to be analyzed subsequently on a computer. We address both problems by introducing a new app, called…

P-n junctions form the basic building blocks for any semiconductor device. Therefore, the complete understanding of the junction characteristics is very important. Although being a widely discussed topic in electronics, there are still some gaps such as finding the value and significance of the junction ideality factor, that needs to be addressed.…

The aim of this study was to quantify clearance mechanics during gait. Seventeen children diagnosed with hemiplegic cerebral palsy underwent a three-dimensional gait analysis evaluation. Dynamic leg lengths were measured from the hip joint center to the heel, to the ankle joint center and to the forefoot throughout the gait cycle. Significant…

Supporting efforts to grow the scientific workforce means articulating and comparing the content of science field stereotypes. To do this, data were collected from the general public [undergraduates (n= 121) and Amazon Mechanical Turk workers (n=223)] as well as from people within science [attendees of an undergraduate conference for women in…

Nowadays, in almost any country in the world, it is difficult to find a young person who has never played with, seen, or heard of the most famous toy in 2017: the fidget spinner. According to Wikipedia: "The fidget spinner is a toy that consists of a ball-bearing in the center of a multi-lobed flat structure made from metal or plastic…

The recent use of Arduino Uno microcontroller boards for automated data acquisition has revolutionized physics education. The Arduino-based physics labs have dramatically lowered the cost of the experimental equipment, while at the same time replacing the commercial apparatus with open hardware and software. Students benefit greatly from rigorous…

There are already several articles describing ways to teach physics using smartphone apps, but what are some experiments you can perform immediately without downloading any additional software? In the spirit of increasing the amount of hands-on activities each of us is doing, and to give us backup activities when you have a few extra minutes of…
