Atomic world has been widely exposed not only to people with some related knowledge but also to scientists and it will be so in the future.

Though many factories have mass-produced x-ray penetrator and electron microscopes to see the inner part of materials, the atomic world has been beyond our vision. This book, however, makes it possible to see the world itself. Given the importance of this subject matter, it will contribute greatly to the future scientific development.

This book makes the atomic study get into a new stage. Owing to this book many elementary particles such as electron, quantum, mason, and neutron, will be newly elucidated in the history of science sooner or later.

We may have to enlarge Dalton's atomic theory and do away with Avogadro's molecular theory after detailed inspection of this book. All hypotheses and theories on an atom may be verified and put in a new way because this book proposes the actual origin of the new atomic world.

Though we believe that a particle accelerator is an instrument which destroys an atom, we do not know whether the nucleus, the band, and other unknown materials are demolished before we can see an atom itself with our own eyes.

I do not want to insist that the atomic world presented in this book covers all hypotheses of the atom which scientists have found and it is everything. A close examination of this book will show that the existing knowledge of atoms in the mind of many scientists is a partial knowledge of it. Atoms are larger in scale than we know.

Usually, the outer image is printed upside-down on the retinae but appears practically upright. And, the penetrated image that is printed upright on the retinae appears practically upside-down. Thus, I used an upward arrow(↑↑↑) in Figure H of Chapter 1 instead of a downward arrow(↓↓↓).

My opinion, based on the experimental facts and physical theories shown in this book, is as follows:

1. The discovery of a three-dimensioned and circle-shaped atom with bands including a nucleus.
2. The invention of a visible light penetrator, a new instrument used to see the structure of a material, which makes it possible to see the atomic world.
3. The discovery of all the physical facts written in Chapter 1 by means of the penetrator.
4. The discovery of a reflected and a penetrated image.
5. The testimony of an atom as a new material through the facts and theories verified with the penetrated image.
6. The discovery of facts and theories on the symmetry of materials.
7. The discovery of physical theory written in Chapter 2 and the establishment of a new material world.
