With its answers to questions such as What is time? and What is space?, this clear, nontechnical treatment makes the principles of relativity more accessible to the general reader. The author gradually introduces Einstein's theory in terms of familiar concepts from high school-level geometry, utilizing more than 60 drawings to illuminate profound yet often simple ideas.

Magnetic Current is a short pamphlet by eccentric sculptor and writer Edward Leedskalnin. Detailing his many experiments with magnets, this work posits that it is not metal itself that is magnetic. Rather, tiny individual magnet particles that circulate in and around the metal give it its pull.
Edward Leedskalnin was born in Latvia in 1887. While his formal education lasted only until 4th grade, he was intensely curious and spent much of his youth...

This edition includes a modern introduction and a list of suggested further reading. René Descartes is perhaps most remembered for declaring, "I think, therefore, I am." First published in 1644, Descartes's Principles of Philosophy elucidates the meaning of those words that ushered in a new era of philosophical thought. Unlike the medieval philosophers who often began by examining the existence and nature of God in a spirit of faith, Descartes begins...

Some efforts have been made to prove negative mass behavior through some experiments performed in mechanics, and other disciplines as well as some theories in electrostatics, but I haven't found research about similar effects at the atomic level, where the most elementary mass given by the atomic nucleus is to be found.Is the second Newton's law still valid with negative mass?What could happen if we make the atom behave in a negative mass regime?Is...

Book Preview: #1 The ancient Greek philosopher Aristotle believed that the earth was a round sphere rather than a flat plate. He knew that eclipses of the moon were caused by the earth coming between the sun and the moon, and that the North Star appeared lower in the sky when viewed in the south than it did in more northerly regions.
#2 Aristotle believed the earth was the center...

Get the Summary of Carlo Rovelli's “The Order of Time” in 20 minutes. Please note: This is a summary & not the original book. Original book introduction: Why do we remember the past and not the future? What does it mean for time to "flow"? Do we exist in time or does time exist in us? In lyric, accessible prose, Carlo Rovelli invites us to consider questions about the nature of time that continue to puzzle physicists and philosophers alike.

The twentieth century gave us two great theories of physics. The general theory of relativity describes the behavior of very large things, and quantum theory the behavior of very small things. In this landmark book, John Gribbin—one of the best-known science writers of the past thirty years—presents his own version of the Holy Grail of physics, the search that has been going on for decades to find a unified “Theory of Everything” that combines...

One of the greatest experimental scientists of all time, Michael Faraday (1791–1867) developed the first electric motor, electric generator, and dynamo - essentially creating the science of electrochemistry. This book, the result of six lectures he delivered to young students at London's Royal Institution, concerns another form of energy - candlelight. Faraday titled the lectures "The Chemical History of a Candle," choosing the subject because,...

Dr. Tyson Klein is a quantum physicist who has dedicated his entire life to his research. At CERN, he analyses data generated by the Large Hadron Collider, the world's biggest and most powerful particle accelerator. Now, Ty believes he's found a pattern in its output. It looks like an organised data stream, being broadcast over what he calls a quantum radio. Could it be a signal from another universe? A message sent from the future? Or something else...
