Description
Laurent Lestarquit and his international team designed and patented two primary signal innovations for the European GALILEO global navigation satellite system (GNSS). Their signalling technology helps ensure the high accuracy of GALILEO, while saving energy and assuring navigational compatibility and/or interoperability with the US GPS and the Russian GLONASS worldwide GNSS systems. The team's developments also allow the use of legacy and lower end...

Every single object is made of different materials that have observable properties. This Miniclip sorts and groups materials based on observable properties such as color, texture, and flexibility. Students are encouraged to think about the suitability of materials for different purposes such as clothing and housing through the examination of materials such as paper, wood, plastic, metal, glass, fabric, and rubber.

What is physics? Find out as the Standard Deviants introduce you to the basics, including scientific notation, numbers and units, and scalars and vectors.The Basics introductory video includes the review of the mathematics necessary for the study of physics. To speak the language of physics requires the ability to use scientific notation and to manipulate exponents, plus an understanding of the metric naming convention. A review of the trigonometry...

The second episode will show how gravity varies across the Earth’s surface. A travelling Gravity Roadshow of scientists and volunteers will cross the UK, measuring gravity using highly accurate scales as they go, to see how the force of gravity varies across the UK. This will allow us to reveal in the show the place in Britain where, according to the laws of physics, you weigh the least.

Nanoparticles are tiny bits of material with a diameter between 1 and 100 nanometers. This clip explores the tiny world of nanoparticles and how their size and structure make them so useful, including the square-cube law and the relationship between volume and surface area. It provides students of middle-to-senior-level science, chemistry, and physics with insights into phenomena at the smallest imaginable scale.

The neutrino experiment formerly known as LBNE has been transformed. The proposed experiment will be the most powerful tool in the world for studying hard-to-catch particles called neutrinos. The first thing scientists are looking for is a fundamental difference between matter and anti-matter. This has been seen in particles called quarks before, but that’s not enough to explain why in fact the universe is dominated by matter over anti-matter. And...

A voyage into the smallest "universe" imaginable: the atom. This program will explore the world of atoms, the subatomic world, and quarks, which are the basic building blocks of all matter. It will also cover the magnifying glass, optical microscope, and tunnel-effect microscope.

Orbital motion of satellites can be explained mathematically, but orbits of both of natural and artificial satellites do not always remain constant. This clip examines escape velocity and energy of orbital systems, including gravitational potential energy in radial gravitational fields in a variety of situations. Senior-level physics students will find it a valuable resource to enhance their understanding of energy in orbital systems.

"At the core of Einstein's general theory of relativity are a set of equations that explain the relationship among gravity, space, and time--possibly the most perfect intellectual achievement of modern physics. For over a century, physicists have been exploring, debating, and at times neglecting Einstein's theory in their quest to uncover the history of the universe, the origin of time, and the evolution of solar systems, stars, and galaxies. In this...
