How does a rainbow form? Is levitation possible? Do time machines exist? What does 'quantum' mean? What is the maximum force value found in nature? Is 'empty space' really empty? Is the universe a set? Which problems in physics are still unsolved?

This site publishes a free physics textbook that tells the story of how it became possible, after 2500 years of exploration, to answer such questions. The book is written to be entertaining, surprising and challenging on every page. With little mathematics, the text explores the most fascinating parts of mechanics, thermodynamics, special and general relativity, electrodynamics, quantum theory and modern attempts at unification. The essence of these fields is summarized in the most simple terms: it is shown how they are based on the notions of minimum entropy, maximum speed, maximum force, minimum change of charge and minimum action.

Buried land mines kill more than 15,000 people each year worldwide. At the current removal rate, it will take about 450 years to clear the world of undetected anti-personnel land mines. Now, researchers from several U.S. universities are training honey bees to locate buried land mines through odor detection.

Appearing like a winged fairy-tale creature poised on a pedestal, this object is actually a billowing tower of cold gas and dust rising from a stellar nursery called the Eagle Nebula. The soaring tower is 9.5 light-years or about 90 trillion kilometres high, about twice the distance from our Sun to the next nearest star.

The Ultra Deep Field obtained by the Hubble Space Telescope is the deepest view into the sky by humankind to date. This image combines 800 frames with a total exposure time of 1 million seconds. The 10.000 galaxies that are visible have distances out to times where the universe was just 800 million years old, one seventeenth of its current age.
