Introduction to Wave Mechanics
Masato MURAKAMI / Kazumasa IIDA / Shinobu KOBAYASHI
The Schrödinger equation is a partial differential equation that can be expressed in three-dimensional spherical coordinates.
As we solve it, the once-mysterious electron orbitals within atoms gradually come into view.
This introductory book on quantum mechanics conveys the thrill and excitement of that discovery, even to readers encountering the subject for the first time.
The challenges and setbacks faced by Heisenberg and his colleagues — a story of researchers who boldly ventured into uncharted territory.

Is Carbon the Enemy of Humankind?
Masato MURAKAMI / Shinobu KOBAYASHI
Is CO₂ Really the Culprit Behind Global Warming?
Carbon dioxide (CO₂) is an essential gas for photosynthesis in plants, the foundation of the Earth's nutrient cycle, and the source of life for plants and animals alike. It is not the enemy of humankind.
