In this paper we present a simple dimensional analysis exercise that allows us to derive the equation for the Hawking temperature of a black hole. The exercise is intended for high school students, and it is developed from a chapter of Stephen Hawking's bestseller "A Brief History of Time."

In 1974, Stephen Hawking theoretically discovered that black holes emit thermal radiation and have a characteristic temperature, known as the "Hawking temperature." The aim of this paper is to present a simple heuristic derivation of the Hawking temperature, based on the Heisenberg uncertainty principle. The result obtained coincides…

Philosophy confronts two existential crises: the threats to its existence from scientists like Stephen Hawking who claim that philosophy is dead; and the threat to life itself from catastrophic climate change. The essay's first theoretical part critiques Nietzsche's claim that philosophy's primary function is to guarantee the future of life. The…

The main aim of this article is to use the case study of comprehensivisation to examine the role of party activists as policy entrepreneurs and public intellectuals during the period 1950-1965. The intention is to widen the traditional notion of the public intellectual in order to better evaluate policy-making processes within the Labour Party. It…

On the surface, "The Gods Must Be Crazy" is a campy confluence of three independent plotlines involving Xi, a Kalahari tribesman, who journeys to the end of the earth to dispose of a Coke bottle that has begun to disrupt the harmony of his community; Mr. Steyn, a white scientist, and the beautiful blonde schoolteacher he escorts through the bush;…

This theoretical review article describes "situated discourse analysis" (SDA) and explores its implications for communication sciences and disorders. Drawing on situated theories of cognition and communication, SDA aims to understand "real-time communicative processes" of people engaging in complex "sociocultural…

What is science? Depending on who is asked, it may mean the pursuit of knowledge, explanations of the everyday world, a difficult subject at school, or a field populated by larger than life characters such as Einstein, Feynman, or Hawking. For the author, science has been and remains an unexpected journey, an adventure and an ever-changing career.…

As the federal government encourages all students to attempt advanced math and science courses, more students with disabilities are enrolling in Advanced Placement (AP) science classes. AP science teachers can better serve these students by understanding the various types of disabilities (whether physical, learning, emotional, or behavioral),…

Street hawking in its simplest form is the selling of things along the roads and from one place to the other. In Nigeria this is done almost all the time by young children both males and females. The girl hawkers come to the cities in groups and then go in different directions of the city to hawk their goods. They remain in the city from the early…

The increasing number of children with profound and multiple learning difficulties means that many schools for children with severe learning difficulties are having to review the curriculum that they offer. In addition, these schools are continuing to question whether a subject-based approach, in line with the National Curriculum, is the most…

I was tangentially aware of gifted education while I was in elementary and middle school, but my first real awareness of the concept came through my work in the University Honors Program at Texas A&M. In truth, I was not yet working for the University Honors Program; I was a graduate assistant for then-Associate Director, Finnie Coleman, who…

The study sought the opinions of Faculty of Education Students of University of Uyo on the behavioural problems of juvenile street hawkers in Uyo metropolis. Five research hypotheses were formulated to guide the study. This cross-sectional survey employed multi-stage random sampling technique in selecting 200 regular undergraduate students in the…

To quote "Will & Grace," the Consumer Electronics Show (CES) in Las Vegas, Nevada, January 7-10, was "a nightmare/delightful!" Five times larger than even the largest library conference, the show's 35 football field-long bazaar of technology marvels and gimmicks--along with thousands of reps hawking them--was almost enough to put a person off…

In this paper it is argued that virtual processes are dispensable fictions. The argument proceeds by a comparison with the phenomenon of quantum tunnelling. Building on an analysis of Levy-Leblond and Balibar, it is argued that, although the phenomenon known as quantum tunnelling certainly occurs and is at the basis of many paradigmatic quantum…

Each of these outstanding selections defies the traditional image of a child "curling up with a good book." Yes, they can be a source of great personal reading, encouraging students of all ages to stretch their skills and their imagination as they interact with the printed page. But these journeys of the scientific imagination seldom end with the…
