An atomic theory is a model developed to explain the properties and behaviors of atoms. As with any scientific theory, an atomic theory is based on scientific evidence available at any given time and serves to suggest future lines of research about atoms. The concept of an atom can be traced to debates among Greek philosophers that took place around the sixth century B.C. One of the questions that interested these thinkers was the nature of matte (more…)
Microscopes have different uses. They are no longer just for use in the science lab at the local high school. The world of the microscope today offers people the option to see objects, such as fossils encased in rocks that are over 650 million years old.
The scopes of today are not like those of yesteryear. Choosing such a device for an individual can be a big deal unless one knows what they need and what they should definitely st (more…)
You breathe air made up of atoms, eat foods composed of atoms and drink water made up of atoms—with a body that itself consists of atoms. The objects you see around you are actually nothing more than photons striking the electrons belonging to the atoms in your eyes.
And what about the things you touch and feel? Those too—hard and soft, rough and smooth, cold or hot—consist of the atoms in your skin interacting on the atoms (more…)
Microscopes are mechanical devices used for viewing objects and materials so minute in size that they are undetectable by the naked eye. The process conducted with such an instrument, called Microscopy, uses the combined schools of optical science and light reflection, controlled and manipulated through lenses, to study small objects at close range.
The basic microscope consists of several complex and interrelated parts: a cylinder t (more…)
