Clear Thinking on Curious Subjects

In the late 1980s, a friend showed off his new speakers. They sounded good. Then his couch was moved two feet forward, and he sat through most of a track without a word, grinning. Nothing had been bought.

That is the argument of this book. Most of what you hear, often 80 percent or more, comes from three things: the speakers, the room, and where the speakers sit in it. Those are rarely where people spend their money. In plain language, the book explains how perception shapes what you think you hear, what digital and vinyl each do well, what room-correction software can and cannot fix, and how to weigh the claims behind the great audio debates.

It also rejects the idea of one correct sound. Some listeners want space and precise imaging. Others want energy and physical impact. Two real systems show how to build toward either one on purpose.

The final chapter, Fix Your System in One Weekend, turns it all into a step-by-step sequence using the equipment you already own. Technical appendices on the physics of hearing, distortion, and loudspeaker behavior serve readers who want more depth.

For anyone building a system, fixing a frustrating one, or wondering why the last upgrade changed so little.

Their war ended thirty years ago, but the guides who walked us through Dubrovnik's shattered and rebuilt streets still carry it in their voices. They remember the shelling. They remember which buildings fell and which neighbors did not come back. Their memories, offered openly to strangers who had barely heard of this war, are the reason this book exists.

The trip began with a family story. In the early 1900s, a young woman crossed the Atlantic to marry the man her sister had left behind, and her granddaughter, the author's wife, wanted to see the land she came from. What started as a scenic tour of the Adriatic coast became something deeper.

The book follows Croatia through its layers: Roman ruins inside living cities, Venetian harbors, centuries under Austria-Hungary, and the long frontier with the Ottoman Empire. It then traces the rise and collapse of Tito's Yugoslavia, the siege of Dubrovnik, the destruction of Vukovar, and the rebuilt country that visitors see today. A timeline and route map keep the history easy to follow.

Richly photographed, this is a book for readers who want to understand a place, not only visit it. Croatia's beauty is real. Knowing what it endured makes it unforgettable.

In November 2004, Navy pilots off the carrier Nimitz chased an object that seemed to move faster than anything known. Every remarkable figure later quoted for its size and speed depends on one number that was never released: its distance. Without the range, there is only an angle that changed.

That gap between seeing something and knowing what it is runs through this entire book. It applies one method to every claim, old or new. What was observed? What does the observation establish, and what does it not? Which other explanations are still standing?

The method is turned on ancient accounts, the best-known UAP cases, and the ways sensors and human perception mislead. Then it turns to the science: what life requires, what thousands of exoplanets reveal, extremophiles, the origin of life, the organic molecules returned from asteroid Bennu, the Drake Equation, and the hunt for technosignatures.

Every major claim ends up in a ledger under one of three headings: established, open, or unsupported. The author keeps his own opinion out of it until the final chapter, where it is clearly marked. Detailed appendices give the case data and sensor physics for readers who want to check the work.

For readers who follow exoplanets, biosignatures, or the UAP debate and want a reliable way to judge the next headline.

Fill a glass of water and set it on the table. It looks like the most ordinary object in the house. Yet its stillness is a standoff between gravity and the tabletop, its surface has a skin made of nothing but water, and the ice cube floating in it is the reason fish survive the winter.

Everyday Physics is built from 133 questions like that, each one standing on its own. Why does popcorn pop? Why do curveballs curve? Why does salt melt ice? Open the book anywhere and start reading. The chapters range across the kitchen, sports, weather, everyday technology, transportation, and your own body.

There are no equations, only plain language and things you can see for yourself. Many questions come with an experiment to try using what is already in your house. Short portraits introduce the scientists who worked the problems out. One feature corrects popular explanations that turned out to be wrong, and another points to questions physics still cannot answer.

Written for everyone, from high school students to parents and lifelong learners. It is also the first book in a series that continues with Everyday Quantum.
