RealClimate » Learning from a simple model: "A lot of what gets discussed here in relation to the greenhouse effect is relatively simple, and yet can be confusing to the lay reader. A useful way of demonstrating that simplicity is to use a stripped down mathematical model that is complex enough to include some interesting physics, but simple enough so that you can just write down the answer.

Mathematician suggests extra dimensions are time-like: "In a recent study, mathematician George Sparling of the University of Pittsburgh examines a fundamental question pondered since the time of Pythagoras, and still vexing scientists today: what is the nature of space and time?

Short answer: Physics is cool, but I'm biased. Longer answer: Physics, as a discipline - especially at an undergraduate level, teaches many things that are important in all walks of life: 1) Problem Solving skills - the typical physics course is more problem solving based than any other subject (except perhaps mathematics) and the problems are often more practical. If you want to be a doctor,

Why Study any Science?Physics is one of the cornerstones of science, so we study physics because we study science. Science itself is important because, beyond the aesthetic arguments, science has an uncountable number of applications. Honestly, few physicists study physics with a view directly towards applications – we tend to research to find out how things work, to satisfy our curiosity.

'March 9, 2006: NASA's Cassini spacecraft may have found evidence of liquid water reservoirs that erupt in Yellowstone-like geysers on Saturn's moon Enceladus.

Definition, Cummutative and Associative Laws The sum of two vectors, written C=A+B, is defined as the vector that results from following vector A to its head and then placing vector B's tail at the head of A and following it in turn. In Cartesian coordinates, this sum is particularly straightforward: Cx = Ax + BxCy = Ay + By Cz = Az + Bz Vector addition is commutative and associative: the

Converting between different system of units Unit conversion is an important skill – a failure to convert from imperial to metric units caused the loss of the . Typically, in physics, we measure speed in meters/second (m/s), but in the outside world other units, like miles/hour (mi/hr) are much more common. How do we convert between them? 1 mi/hr = x m/s We want to find the unknown “x” – it is

Definition: In turbulent flow, the streamlines are crossing each other constantly and are tangled in a random way. The particles of the fluid move in a disordered manner in irregular paths, resulting in an exchange of momentum from one portion of a fluid to another. Turbulent flow takes over from laminar flow when high values of the Reynolds number are reached. Also Known As: turbulence

Physics Pedagogy versus Physics Research in General RelativityMost courses (this one included) are taught in a “top down” fashion: Starting with the principles of relativity then exploring differential geometry as a beautiful mathematical structure that progresses to the field equations and then to the explanations of effects like the Anomalous precession of the perihelion of Mercury.

Seeing the Weight Of AirDid you know that air has mass? Because the weight of the atmosphere has been pressing down on you all your life and your body is adapted to it, you don't even notice it! But try traveling to a place at high altitude and you'll quickly notice it's lack. Even if you are intellectually aware of the mass of air, there are a few experiments like this one (and the "air

Estimate the total weight of the air in the atmosphere. The radius of the Earth is approximately 6000 km. 14.7psi indicates that, above every square inch on the Earth’s surface there is enough air to weigh 14.7 pounds. First we need to convert this

In 1988, a group of Japanese physicists filmed the motion of Intertial Gravity waves in a tank of water. These waves, caused by a vibrating rod at the center of the tank, propagate out wards as disturbances in the density (and velocity, pressure) of the fluid. However, unlike the "usual" visualization of waves as spreading outwards isotropically, these waves spread in a "St Andrew's" cross

Large, energetic vortex structures commonly form in irregular or turbulent two-dimensional flows. Familiar examples are Jupiter's Red Spot or hurricanes and typhoons on Earth. What isthe mechanism that transfers energy from small-scale vortices to these often long-lived, large-scale circulation patterns? Many suggestions have been made, such as a merger of small vortices into larger ones.

The smallest wire width in mass produced electronic devices is about 50 nm, or about 500 atoms across. The ultimate limit of thinness would be wires only one atom wide. Such wires can be made now, although not for any working electronic device, and it is useful to know their properties for future reference.

Making Sure Your Science Fair Project Topic is Right Choosing a topic is one one of the most crucial parts of this process. It is important that you choose a topic that is “right.” By this, I don't mean that you need to be on the absolute edge of physics research – there is no need for your project to be about string theory or Bose-Einstein Condensation (although, if you relish a challenge...!).
