Calculate the Top Quark Mass
Students use conservation of momentum to calculate the mass of the top quark. This activity examines the fingerprint of a top/antitop production that took place in the D-Zero Detector at Fermilab on July 9, 1995. This activity will build on student understanding of vector addition and depends upon only a small amount of particle physics explanation.

Applying Ohm's Law to Semiconductors
This project allows students to apply concepts of momentum conservation and energy conservation from classical physics. However, here they are not enough: they must be combined with modern physics, using concepts from relativity and particle physics as well as modern units that put energy, mass, and momentum in terms of MeV and GeV. Most important, students will learn about both fundamental and cutting-edge physics by actually doing what physicists do.

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.

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
