Essential Science for Teachers: Physical Science Session 3. Physical Changes and Conservation of Mat
What happens when sugar is dissolved in a glass of water or when a pot of water on the stove boils away? Do things ever really "disappear"? In everyday life, observations that things "disappear" or "appear" seem to contradict one of the fundamental laws of nature: matter can be neither created nor destroyed. In this session, participants learn how the principles of the particle model are consistent with conservation of matter.,The segment shows the interviewer trying to find out the student's id

NASA KSNN What is gravity?
Gravity is one of the fundamental forces of nature. No one really understands exactly why, but gravity is a force that pulls objects toward each other. The mass of the objects and distance between the objects affects the strength of the force of gravity. Greater masses attract with more force and the force weakens as the objects get further apart.

Pendulum Lab
Play with one or two pendulums and discover how the period of a simple pendulum depends on the length of the string, the mass of the pendulum bob, and the amplitude of the swing. It's easy to measure the period using the photogate timer. You can vary friction and the strength of gravity. Use the pendulum to find the value of g on planet X. Notice the anharmonic behavior at large amplitude.

Lunar Lander
Can you avoid the boulder field and land safely, just before your fuel runs out, as Neil Armstrong did in 1969? Our version of this classic video game accurately simulates the real motion of the lunar lander with the correct mass, thrust, fuel consumption rate, and lunar gravity. The real lunar lander is very hard to control.

Urban Nomads
China is a country in superlative transition. Media attention focuses primarily on the economic miracle and burgeoning political power, while the interwoven and critically important story of mass human migration remains a postscript. Driven from crumbling countryside economics, 200 million Chinese have moved to the cities, serving as cogs in an engine powering unprecedented growth. Though they are changing every facet of Chinese life, these internal migrants are, by law and practice, second-clas

Terror and Consent: The Wars for the Twenty-First Century
The threat of terrorism is now part of the landscape of daily lives all over the world, yet we have hardly begun to think properly about it. In his new book Terror and Consent and in this lecture Professor Bobbitt argues that we are fighting these wars with weapons and concepts which though useful to us in previous conflicts have now been superseded. He aims to provide a fundamental rethinking of most generally accepted ideas about terror in the modern world - what it is, how it operates and ab

Living in an era of global terror
In this podcast, Professor Richard Aldrich from the School of Politics and International Relations, discusses the impact of globalisation, the opportunities this affords to global terrorists and the challenges faced by the intelligence services. Globalisation has led to a free flow of money, people and ideas, which has benefited many people in the West in recent years and enhanced our standard of living, but the price paid is a reduction in security. As we see a shift towards a de-regulated glob

7.2 Coding of information in the higher auditory centres

We have seen that in the cochlear nerve, information about sound intensity is coded for in two ways: the firing rates of neurons and the number of neurons active. These two mechanisms of coding signal intensity are found throughout the auditory pathway and are believed to be the neural correlates of perceived loudness. The tonotopic organisation of the auditory nerve is also preserved throughout the auditory pathway; there are tonotopic maps within each of the auditory nerve relay nuclei, the
