Plasma

Solid, liquid, gas - and then the state that makes up almost everything else in the visible universe. Somehow, it's the one nobody taught you.

Every star in the sky is plasma. So is lightning, the aurora, the glowing heart of a neon sign, and the fireball inside an experimental fusion reactor. More than 99 percent of the visible universe exists in this fourth state - matter so energized its atoms have been torn apart into a soup of charged particles that moves, glows, and behaves like nothing else in nature.

Angus Walpole delivers the complete guide, from the first mysterious glowing tubes to the technologies that may power civilization, in clear, vivid language with no equations required.

Inside, you will discover:

• What plasma actually is - and the threshold where ordinary gas transforms into something extraordinary
• The birth of plasma physics - Crookes tubes, cathode rays, and Irving Langmuir's christening of a new state of matter
• Collective behavior - why plasma acts as a whole, like a crowd rather than a collection of strangers
• Stars up close - the Sun's corona, flares, solar wind, and the plasma weather that reaches Earth
• Lightning and auroras - nature's electric plasma, from thunderclouds to the magnetosphere
• Magnetic reconnection - the explosive process behind solar flares and the northern lights
• The fusion dream - tokamaks, stellarators, laser fusion, and the honest state of the quest for star power
• Plasma in your life - from screens and surgical tools to plasma medicine and spacecraft engines

From the laboratory bench to the edge of the galaxy, this is the definitive tour of the state of matter that lights the universe.

Look at any star tonight. Now learn what it's actually made of.
