Social media has become a crucial form of communication and social interaction. However, users are often unaware of the possible ramifications of using social media platforms or how their user-generated content is being used. The problem addressed in this study is that sexting, bullying, and cyberstalking occurs in all social media platforms…

Smartphone ownership and use by adolescents have increased rapidly over the past decade and a half. Although some educators anticipated benefits of smartphones for learning, increasing smartphone use has raised numerous concerns in school environments, including the possibility that the mere presence of a smartphone reduces students' cognitive…

This paper describes an experimental investigation of the skin depth effect for electromagnetic waves in salt water using a cell phone that is immersed to a critical depth where it no longer responds when called. We show that this critical depth is directly proportional to the theoretical skin depth for a range of salt concentrations.

Understanding Physics is a great end in itself, but is also crucial to keep pace with developments in modern technology. Wireless power transfer, known to many only as a means to charge electric toothbrushes, will soon be commonplace in charging phones, electric cars and implanted medical devices. This article outlines how to produce and use a…

Through the Internet of Things (IoT) people and devices are communicating and interacting with one another continuously. This includes devices such as thermostats, televisions, voice activated speakers (Amazon Echo), smartphones, tablets, and wearables (Fitbit). This is accomplished through the IoT using uniquely identifiable radio tags, sensors,…

Millennials: a generation always in the news--and not just in mainstream media but in the more powerful and influential news outlet, social media. This generation has attention unlike any before (at least not since the Baby Boomers), and it is changing our world in ways we have yet to fully realize. Millennials are challenging the norms of…

The use of digital technology has grown rapidly during the last couple of decades. During use, mobile phones and cordless phones emit radiofrequency (RF) radiation. No previous generation has been exposed during childhood and adolescence to this kind of radiation. The brain is the main target organ for RF emissions from the handheld wireless…

Electromagnetic radiation is one of the most important issues affecting peoples' lives today. The misunderstanding of students and the general population of the effects of electromagnetic radiation is a problem which must be eliminated. Thus, a discussion about ionising and non-ionising radiation focusing on the crucial issue of radiation emitted…

Until relatively recently, financial planning typically involved investment advisers advising relatively wealthy and financially literate individuals about where to place their abundant disposable incomes. Today, many financial planners are focused on advising individuals with modest incomes and little understanding of finance how best to manage…

When measuring the speed of an object with a video camera, a correction may be needed for the time taken by the camera to acquire the image in each frame. Examples are given where the correction is quite significant.

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…

The emergence of new technologies has changed the way people communicate. Social media have allowed businesses to connect with customers and to market their products more efficiently. However, these platforms also allow customers to share information and opinions with the company and fellow customers, diverting from previous online service…

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…

Today, the mobile technologies and Information and Communication Technology development opened the door on new methods and pedagogies of learning. We are talking here about the mobile learning and the flipped classroom approaches. The flipped classroom means that the activities that have traditionally taken place inside the classroom now take…

This study examined the extent, motives and impact of mobile phone photo note-taking on students' learning at Dar es Salaam University College of Education (DUCE) in Tanzania. It employed the mixed methods approach. A sample of 310 respondents was drawn using a multi stage sampling technique which involved stratified random sampling at the first…
