- Introductory Chemistry by Iwanami Shoten
A group of Japanese chemists launched a project to disseminate a series of “Introduction to Chemistry” by the Internet. As the representative of the group, the author wishes to introduce the purpose of this project, and the structure of the series, to the potential users of the textbooks. For this purpose, the author prepared two short articles, one is the Q&A on the project, and the other Preface to the series. We wish the series would be used by many young students and citizens who have some difficulty in purchasing textbooks though they are very much interested in chemistry
- Batholith (Wikipedia)
A batholith (from Ancient Greek bathos ‘depth’ and lithos ‘rock’) is a large mass of intrusive igneous rock (also called plutonic rock), larger than 100 km2 (40 sq mi) in area, that forms from cooled magma deep in the Earth’s crust. Batholiths are almost always made mostly of felsic or intermediate rock types, such as granite, quartz monzonite, or diorite (see also granite dome).
