# Science related resources ### Slack If you have a specific question, sometimes the easiest solution is to post it to the Slack group and crowdsource the answer. ### Books: LBNL, UC Berkeley, public libraries, and the “group library” As an LBNL employee, you can get access to almost any book you’d like using various channels: * LBNL has its own library, but it is small and unlikely to contain the book you want. * LBNL employees can borrow books from the UC Berkeley Library collection using your LBNL ID. You can even reserve the book online and have it delivered to the LBNL library office in building 50, saving you a trip down to campus (this is what I do). Log in through via “My Oskicat” and choose the LBNL login option. * Your local library (e.g., Berkeley Public Library) often participates in Interlibrary loans. For example, the “Link+” system at Berkeley Public Library connects to many other university libraries in the area. Again, you can have the items delivered to your local library. This service is extremely useful when an item cannot be found at UC Berkeley or if that item has a long waiting list. * Our group has some technical books that you can loan. See **Appendix K: Group library**. * If you are struggling to find a paper (for example, it is a translation of a russian article and was published in a now defunct journal with no online archive in the 1940’s) then send a polite email to with as many details as possible. Prepare to be impressed. You can also purchase books with research funds. ### Materials Science “Don’t despair of standard dull textbooks. Just close the book once in awhile and think what they just said in your own terms as a revelation of the spirit and wonder of nature”. -- Richard Feynman It can be difficult to find resources that explain concepts in materials science clearly. Often, struggling through multiple attempts to understand a topic using several different resources in a patchwork and non-linear fashion is the only way forward. That said, the resources listed below are particularly helpful. ### Density functional theory For beginners to density functional theory, I would recommend the book **“Density Functional Theory: A Practical Introduction”,** which truly achieves what it states by providing physical insights and relevant information rather than just list equations. A copy is available within the group. If you are interested to explore applications of density functional theory, you might try the E-book from Professor John Kitchin: [https://github.com/jkitchin/dft-book ](https://github.com/jkitchin/dft-book) Note that this book has chosen to use the Atomic Simulation Environment (ASE) to set up simulations rather than the pymatgen code that we prefer, but that is a minor point. Finally, for specific calculations with VASP, there are resources online from a 2016 workshop conducted at LBNL, including videos and training materials: [http://www.nersc.gov/users/training/events/3-day-vasp-workshop/ ]() ### General materials science topics To gain a quick introduction to many topics in materials science, you might try the (horribly-named) web site from the University of Cambridge: Dissemination of IT for the Promotion of Materials Science (DoITPoMS): The explanations in this site are very basic, but what they do cover is well-explained and incorporates helpful visuals. Although you won’t ever master a topic from this site, it is often a good starting point that can help you unlock a more intermediate resource. There are also some nice chapters in the following e-book: \ For example, Chapter 5 has a nice rundown of common crystal structures. ### Online tools #### A nice tool for visualizing phonon modes is: [http://henriquemiranda.github.io/phononwebsite/phonon.html ]() #### A nice tool for visualizing Brillouin zones is: \ Note, the high-symmetry labels may occasionally differ from those on the Materials Project. #### Databases and information resources The LBNL library maintains a subscription to many tools and databases for materials science such as SpringerMaterials. A list of these is available here: \ --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://hackingmaterials.gitbook.io/hm-handbook/appendix/science-related-resources.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
