Protomineral world as a new World of neglected dimensions

The paper is dedicated to the 140th anniversary of W. Ostwald’s birth and to the centenary of publishing of the Russian edition of his book «World of neglected dimensions», which changed ideas about micro- and nanoworld. We briefly observed results of the first and second stages of research breakthrough into the world of micro- and nanosized particles. This recently discovered understudied world between separate atoms and molecules and between minerals is called a protomineral world. This world is suggested to be called a new «World of neglected dimensions» by analogy with W. Ostwald’s book. The key objects of the protomineral world are precrystalization clusters in mineral-forming environments named «hidden» phase clusters or quatarons. We showed that the future investigation of structural forms of formation and existence of the protomineral matter would be connected with the use of the free electron laser and instruments of attosecond physics.
