Nature of Charge
Published on 2009-07-25 15:05:00
The concept of electrical charge existed long before our knowledge of why it works. You walk across the floor and get a spark from the door knob, your socks stick to your sweater in the dryer, or the screen of the computer attracts dust. These type > read more
Droplets move to microfluidic chamber music
Published on 2009-07-25 15:04:00
In principle, setting a droplet in motion inside a microfluidic channel is straightforward: Apply pressure and the liquid flows. In practice, however, precise control of droplet flow simultaneously along multiple channels is technically challenging; > read more
Nanotube growth caught on camera
Published on 2009-07-25 15:03:00
23 July 2009French and US researchers have produced the first video evidence that carbon nanotubes turn as they grow. Their films, showing atoms being added in a regular pattern at the growing tip of a nanotube, like bricks to a round tower, support > read more
Reflection and Plane Mirrors
Published on 2009-06-23 13:44:00
When any wave encounters an object it can do one of three things; it can bounce off the object (reflection), it can go into the object (refraction), or it can go past the object (diffraction). In each case changes in the light’s path occurs. Eve > read more
Employment in Physics
Published on 2009-06-23 13:43:00
There have been frequent questions on the kinds of employment that are available for physicists. That question is very difficult to answer, because it depends on a number of factors, such as where you are, what degree you obtained, what area of speci > read more
Does spooky action at a distance allow faster than light communication?
Published on 2009-06-23 13:41:00
It is often said that scientists do their best work while young. With Albert Einstein this certainly seems to have been the case. Before the age of 40 he developed special relativity, laid the groundwork for quantum theory by explaining the photoelec > read more
Mental Gymnastics
Published on 2009-06-23 13:40:00
While we enter physics to study the fascinating world of black holes, quarks and the quantum, the brutal truth is that mathematics is the central tool of the physicist. Gauss called mathematics the "Queen of the Sciences", and with good reason. If yo > read more
Relevance of Clean Coal Technology Today
Published on 2009-06-23 13:39:00
As intellectuals’ world over are harping on the clean usage of coal or how cleaner coal can be, industrial nations are once again on the back foot, and many of them have asked their scientists to actively pursue Clean Coal technologies, and come up > read more
