Sean Carroll: Distant time and the hint of a multiverse

At TEDxCaltech, cosmologist Sean Carroll attacks -- in an entertaining and thought-provoking tour through the nature of time and the universe -- a deceptively simple question: Why does time exist at all? The potential answers point to a surprising view of the nature of the universe, and our place in it.

What is a Force?

Force is a central concept in physics. By analysing the forces on an object, its resulting motion can be determined. But what exactly is a force? The word force is used in everyday language in a variety of contexts, only some of which reflect the scientific definition of force. In this video, people at Victoria Park in Sydney are interviewed on their ideas of force and the forces that act on them.

Reflection from an impedance discontinuity

Two segments of the Bell Labs apparatus are connected. The segments have different impedance. When a pulse travels from high impedance to low impedance, it is reflected with positive polarity and transmitted with positive polarity. When a pulse travels from low impedance to high impedance, it is reflected with negative polarity and transmitted with positive polarity.

Eureka! Episode 28 - Heat as Energy

Heat is produced whenever there is movement and friction between two objects. Since movement is a form of energy, it follows that heat must also be a form of energy.

Steel Ball Dropped in a Viscous Fluid

Five steel balls of different sizes are dropped into corn syrup. The balls reach a constant velocity shortly after entering the fluid. The velocity is constrained due to the drag balancing the force of gravity in the fluid. This demonstrates the relationship between the size of the ball and the maximum velocity it can obtain.

Electric Generator

This is an alternating current generator: a conducting coil (shown in yellow) rotates inside a magnetic field (the field lines are green here). The vector "A" is perpendicular to the area of the coil (its magnitude is the area of the coil). During rotation of the coil, the magnetic flux changes and an alternating current is induced in the coil. The first graph show the magnetic flux, the other graph shows current intensity.

Egg Experiment to Demonstrate Inertia

If you spin a raw egg and then stop it, it will start spinning again without you having to touch it. A boiled egg, on the other hand, stops and stays stopped. Why is this? Well a raw egg contains a yolk that moves inside the egg independently of the shell. If you stop the shell, the yolk inside continues to move due to its inertia and it therefore gets the egg spinning again.

Exploring the universe: Schools Lecture 2009

The Institute of Physics Schools and Colleges Lecture 2009 is delivered by astronomer Dr Andrew Newsam. This lecture will reveal how:

• Modern telescopes can be used by astronomers to look at the universe in ever greater detail;
• Progress in technology allows astronomers to observe things further and further away and therefore further back in time;
• Astronomical observations can be used to learn more about the origins and future of the universe.

The Difference Between Mass and Weight

There is a common perception that weight and mass are basically the same thing. This video aims to tease out the difference between mass and weight by asking people what makes a car difficult to push. The standard answer is that it is difficult to push because it's heavy. But heaviness is a measure of weight, the gravitational pull of the Earth attracting the car to Earth's center. When the car is pushed on a flat road, the force of gravity does not oppose the motion. Instead the resistance felt is an indication of the car's mass which determines its inertia. Inertia is the property of matter that means it tends to resist acceleration - the greater the mass, the less the acceleration for a given amount of force.

Lecture 16:  Hubble's Law and the Big Bang

The third and final part of the course begins, consisting of a series of lectures on cosmology. A brief history of how cosmology developed into a scientific subject is offered. The discovery of dark energy, along with dark matter, played a crucial role in the development of cosmology. The lecture then discusses the discovery of spiral nebulae in 1920, as well as the "Great Debate" over what they were. Hubble's famous redshift diagram is presented as the basis for Hubble's Constant and Big Bang cosmology. The difficulty of measuring distance of objects in space, and how to do it using the parallax method and the standard candle method, are discussed. Measure brightness using the magnitude scale is explained. Class ends with a review of logarithms.
