Science has been a historically male-dominated field, but without the contributions of these three women, we wouldn't have today's knowledge of radioactivity, or have computers that work as well as they do (if at all), or understand the way the universe as a whole works. Discover the main contributions of each of these women in science here.
If the mind is a fire to be kindled, finding the combination of fuel and ignition that will light a child's love for learning is an enormous challenge. A simple instrument like a radiometer may be one of the sparks that will inspire kids to learn. These inexpensive gadgets are fun, interesting, and exist outside of cyberspace.
Action and thriller movies rake in the cash. Fine. It's an indication of a huge following. Sometimes, though, we can't help but think that some of the ideas handed by these movies are very unlikely, especially when science concepts come into play. Case in point: the villain cuts the cable and the poor elevator, with the protagonist trapped inside, plummets down the basement. Who wouldn't go frantic?
The vast atomic space between sub-atomic particles such as protons, neutrons and electrons, leaves one to logically conclude that all matter should be permeable and/or invisible rather than solid. Fortunately, science has found a logical answer to this question, enabling us to make sense out of the physical universe as we know it.
An electrical battery is one or more electrochemical cells that convert stored chemical energy into electrical energy. Since the invention of the first battery n 1800 by alessandro volta and especially since the technically improved daniell cell in 1836. There are two types of batteries: primary batteries and secondary batteries, which are designed to be recharged and used multiple times.
Sometime, in the course of next few weeks an elite group of scientists and engineers are going to assemble in a control room at the Large Hadron Collider, world’s largest particle accelerator. They will feed a series of directives into their computers that will split trillions of protons into two beams coruscating in opposite directions inside an oval tunnel, buried deep beneath the earth.
Have you ever gone camping, fallen asleep, and woke up shivering and having to start your fire from scratch? Or maybe you're just going through that cord of wood at an alarming rate? Or perhaps you've tried cooking on a campfire and burned everything to a cinder? Never fear, by learning how to bank a fire and manage the heat, you'll be in control of the fire and how it burns!
Physicists study a wide range of physical phenomena spanning all length scales: from the subatomic particles of which all ordinary matter is made to the behavior of the material universe as a whole. Physicists may specialize in areas such as particle physics, atomic and molecular physics, condensed-matter...
Quantum physics deals with the smallest elements of matter known as quarks. Human beings, in most scenarios, are only able to examine the world on a macro level. It was not until relatively recent time that we were even able to examine the world around us on...
Inventions and inventors: the story of the telegraph. Like many inventions, the telegraph developed from the advancement and collaboration of multiple inventions and inventors.
In 1921 Mr. William Hamilton Shortt patented the world's most accurate pendulum clock. This article is a brief over of the clocks features with a link to a shockwave animation of the Shortt clock design.
