Mineralogy

Image
 Mineralogy is a subject of geology specializing in the scientific study of the chemistry, crystal structure, and physical (including optical) properties of minerals and mineralized artifacts.   Silicates, oxides, sulfates, sulfides, carbonates, native elements, and halides are all major mineral groups.   Becoming a mineralogist requires at a minimum a college degree and often postgraduate work. Since most mineralogists work in research or teaching a PhD is the commonest degree that is required. To prepare for this you need to take a college preparatory track in high school.   Georg Agricola a name for German scientist Georg Agricola.   A career in geology is well compensated, with a variety of different career paths and job titles. The main types of careers for geologists are in academia, working for the government (USGS), environmental consulting, oil and gas industry, or mining industry.

Natural

 Natural philosophy was the philosophical study of nature and the physical universe that was dominant before the development of modern science. It is considered to be the precursor of natural science. Nature, according to Aristotle, is an inner principle of change and being at rest (Physics 2.1, 192b20–23). This means that when an entity moves or is at rest according to its nature reference to its nature may serve as an explanation of the event. Aristotle regarded psychology as a part of natural philosophy, and he wrote much about the philosophy of mind. A soul, Aristotle says, is “the actuality of a body that has life,” where life means the capacity for self-sustenance, growth, and reproduction Yet philosophy differs in a fundamental way from art, literature or religion, as its etymological meaning is “the love of wisdom,” which implies a significant degree of objective knowledge. So, philosophy doesn't, as a whole, assume that any fundamental rules exist upon which to build ...

Magnetism

 Magnetism   is a class of physical phenomena that are mediated by magnetic fields. Electric currents and the magnetic moments of elementary particles give rise to a magnetic field, which acts on other currents and magnetic moments. Magnetism is one aspect of the combined phenomenon of electromagnetism.   There are six basic types of magnetization: (1) diamagnetism, (2) paramagnetism, (3) ferromagnetism, (4) antiferromagnetism, (5) ferrimagnetism, and (6) superparamagnetism. Diamagnetism arises from the orbiting electrons surrounding each atomic nucleus.   Magnets don't need gravity or air. Instead, their power comes from the electromagnetic field they generate all by themselves. One class of magnets, called electromagnets, does need electricity to work.   Magnets are surrounded by an invisible magnetic field that is made by the movement of electrons, the subatomic particles that circle the nucleus of an atom. The hyperactivity of these electrons gives magnets t...
