Physics (Greek: physis – φύσις meaning "nature") is a natural science; it is the study of matter[1] and its motion through spacetime and all that derives from these, such as energy and force.[2] More broadly, it is the general analysis of nature, conducted in order to understand how the world and universe behave.[3][4]
Physics is one of the oldest academic disciplines, perhaps the oldest through its inclusion of astronomy.[5] Over the last two millennia, physics had been considered synonymous with philosophy, chemistry, and certain branches of mathematics and biology, but during the Scientific Revolution in the 16th century, it emerged to become a unique modern science in its own right.[6] However, in some subject areas such as in mathematical physics and quantum chemistry, the boundaries of physics remain difficult to distinguish.
Physics is both significant and influential, in part because advances in its understanding have often translated into new technologies, but also because new ideas in physics often resonate with the other sciences, mathematics and philosophy.
For example, advances in the understanding of electromagnetism or nuclear physics led directly to the development of new products which have dramatically transformed modern-day society (e.g., television, computers, and domestic appliances); advances in thermodynamics led to the development of motorized transport; and advances in mechanics inspired the development of calculus.

15x They also went on to show the X1600XT as 2x faster than Ageia and the X1900XTX being 9x faster Whatever the numbers they can put up a demo with a lot of rocks rolling down a hill Big grain of salt time there is no game that runs across Havok and PhysX right now so any numbers appear to be theoretical Same with games that run physics across NV and ATI hardware

Q. I need to do a presentation with three demonstrations of physics and the theme is going to be photography. It doesn't have to be completely photography related but something that will demonstrate the optics that is in photography. I was thinking about making a few camera obscuras as one demo but i need two more. Please help!

A. Camera obscura is great way to go. I've made cyanotypes, and those are a great way to get a feel for how a photosensitive negative works. You can contact print negatives or make a photogram by simply laying an object on the paper and exposing it to light. Albumen prints are some of the first negative materials, but not the easiest to reproduce. Lenses can be fun on their own. If you have an SLR lens, you can hold it above a piece of paper, and by playing with distance and the focusing ring, it becomes a mini projector throwing an image onto your paper.
