This California State University Northridge essay on the "Nature of Science, the Scientific Method, and Measurement" includes a historical perspective.

This guide focuses on everyday substances and how we can change their properties by adding heat or cold, physically manipulating them, or mixing them together.

A good explanation of basic quantum theory.

Computers evolve into PCs, researchers discover one new subatomic particle after another and the space age gives our psyches and science a new context.

The first telegraphs are constructed and Michael Faraday produces much of his brilliant and enduring research into electricity and magnetism, inventing the first primitive transformer and generator.

Scientists take important steps toward a fuller understanding of electricity, as well as some fruitful missteps, including an elaborate but incorrect theory on animal magnetism that sets the stage for a groundbreaking invention.

Aided by tools such as static electricity machines and Leyden jars, scientists continue their experiments into the fundamentals of magnetism and electricity.

Scientists' understanding of the structure of the atom and of its component particles grows, the phone and radio become common, and the modern television is born.

The telephone and first practical incandescent light bulb are invented while the word "electron" enters the scientific lexicon.

Alessandro Volta invents the first primitive battery, discovering that electricity can be generated through chemical processes; scientists quickly seize on the new tool to invent electric lighting. Meanwhile, a profound insight into the...

New tools such as special microscopes and the cyclotron take research to higher levels, while average citizens enjoy novel amenities such as the FM radio.

Defense-related research leads to the computer, the world enters the atomic age and TV conquers America.

A detailed explanation of the Higgs Boson particle and the science of particle physics. Discusses the history of the search for this particle, the ongoing research with the Large Hadron Collider at CERN in Europe, and what is known so...

Gerd Binnig co-developed the scanning tunneling microscope (STM) with Heinrich Rohrer. The STM allowed scientists entry into the atomic world in a new way and was a major advance in the field of nanotechnology. For their achievement,...

The integrated circuit fueled the rise of microelectronics in the latter half of the twentieth century and paved the way for the Information Age. An American engineer, Jack Kilby, invented the integrated circuit in 1958, shortly after he...

Heike Kamerlingh Onnes was a Dutch physicist who first observed the phenomenon of superconductivity while carrying out pioneering work in the field of cryogenics. An important step on the way to this discovery was his success in...

Isidor Isaac Rabi won the Nobel Prize in Physics in 1944 for his development of a technique for measuring the magnetic characteristics of atomic nuclei. Rabi's technique was based on the resonance principle first described by Irish...

At the turn of the 19th century, scientists were beginning to gain a rudimentary understanding of electricity and magnetism, but they knew almost nothing about the relationship between the two. Baltic German physicist Heinrich Lenz took...

A biography of Dr. Charles Liu, an astrophysicist at the American Museum of Natural History focused on his drive to become an astrophysicist.

The life and philosophical treatises of Aristotle (384-322 BCE) are surveyed, including his writings on biology, zoology and physics.

This site from Fordham University is an exerpt from Newton's famous "Principia."

A brief look at the life of Aristotle followed by a short discussion of his ideas about physics.

Links to many video-clip based lessons in the areas of health, English language arts & drama, mathematics, music, biology, earth science, inventions, astronomy, physics, chemistry, U.S. history and culture, and world history and...
