Rutherford's classic experiment consisted in bombarding a thin gold foil with particles (helium nuclei). He expected that some particles would be slightly deflected by the positive charge inside the atoms. Most went through without much change, some were deflected, and surprisingly, some came straight back. This led Ru...

This article assumes basic programming experience with delegates. Delegates are a .NET framework feature that allows for type-safe function pointers. Actually, they are a bit more than function pointers, because they are object oriented, as their second name -bound method references- expresses. It means that the method...
(Medical Xpress)—Scientists have until now not fully understood how animals see in color, since visual pigments in eyes contain exactly the same chromophore (light absorbing segment of the molecule) and yet can absorb different wavelengths of light.

You can learn a lot about sonic booms by looking at the wakes boats leave in the water. If you toss a pebble in a pond, little waves will form in concentric circles and propagate away from the point of impact. If a boat travels through the pond at 3 to 5 miles per hour, little waves will propagate in the same way both ...

The term hydrocephalus comes from the Greek "hydro," meaning "water," and "cephalus," meaning "head." Hydrocephalus, then, is an abnormal accumulation of water-like fluid in the head. The fluid, called cerebrospinal fluid (CSF), is made in the spaces of the brain called ventricles. CSF circulates around the brain and s...
Flame Colors as Chemical Indicators Though not as definitive as the spectral fingerprints from atomic spectra, the colors produced by chemicals when inserted into a flame can be used to identify some constituents of minerals. One procedure used was to put a small amount of the chemical on a small loop of platinum wire ...
SOME birds learn to recognise members of their own species by comparing feathers. Most birds learn to identify their species by studying their nestmates and parents. But parasites such as cuckoos and cowbirds are reared by complete strangers, so they must have a different system. Mark Hauber and his colleagues at Corne...
Influenza, or flu, is a respiratory infection caused by a variety of flu viruses.

We’re learning a lot more about how planets interact with each other gravitationally. ‘Resonance’ is the operative term here. When planets are locked in a 2:1 orbital resonance, the outer planet orbits the host star once for every two orbits of the inner planet. A 3:2 resonance occurs when the outer planet orbits the s...

Projectile motion has two components: horizontal motion and vertical motion. The two components are independent, to they have no effect on each other. When the two motions are combined, they form a curved path. Some examples are a frog leaping, water sprayed by a sprinkler, a swimmer diving into water, balls being jugg...
The Voronoi pattern is basically regions around points such that all the area in each region is the closest to the point it surrounds. So if you have just two points in space then the pattern is merely a line dividing the region in two midway between them perpendicular to a line joining the two points. As you drop more...

It might seem strange, but counting is one of the most difficult things in mathematics sometimes. In fact, it won't be far from the truth to call combinatorics the art of arranging objects and counting them. Brute force techniques, when objects are counted by enumerating all possibilities usually are doomed to fail in ...
We are, of course, talking about plate tectonics. Earlier research suggested the western edge of the North American continent was formed by the conveyor belt-like movement eastward of a single oceanic plate called the Farallon Plate.
