When is a bungee jumper's acceleration max
The video asks students to predict when a bungee jumper experiences maximum acceleration. The answer is at the very bottom of the jump. This is often counter-intuitive as the velocity at this point is almost zero.
However, acceleration is the rate of change of velocity over time, a = Δv/Δt...
When everything grinds to a halt because of the snow, one small boy and his teddy bear refuse to allow the weather to spoil their fun. They embark on an amazing journey in which they ride a polar bear and meet huge...
In Hubbert's Peak and Beyond Oil, the geologist Kenneth S. Deffeyes laid out his rationale for concluding that world oil production would continue to follow a bell-shaped curve, with the peak occurring in 2005 - in keeping with the projections of his former colleague, M. King Hubbert. In this book...
In When the Adults Change, Everything Changes: Seismic Shifts in School Behaviour, Paul Dix upends the debate on behaviour management in schools and offers effective tips and strategies that serve to end the search for change in children and turn the focus back on the adults.

When the Chips Are Down
This physics extension module from the Salters' Science course focuses on the physics and electronics behind each part of a television set. Production of electron beams and their deflection by electrical or magnetic fields are shown and students see how colours can be...
When the Drugs Don't Work
This Catalyst article explains why there are many anti-bacterial drugs but few antivirals. There are millions of bacteria everywhere – on skin, in the gut, and on food. Bacteria have been troubling human beings for as long as they have been around, so a lot of effort has been directed into finding ways to fight...
The demographic explosion and the colonisation of new areas have considerably increased the exposure of populations to natural risks. The proliferation of megalopolises often with poorly controlled planning has simultaneously increased the vulnerability of our societies to disasters.
Although still little...
