If you don’t know about arXiv.org, it’s a repository of electronic preprints of scientific papers that have not undergone a full peer-review maintained by Cornell University Library.

The system is not meant to replace the traditional scientific journal system, but supplement it. Over a million papers on various scientific topics are included in the arXiv, and Garrett Beatty’s open-source arXiv eXplorer can search, view, and download PDF versions of available papers, all for free.

MEL Chemistry

MEL Science

MEL chemistry is a great way to see what all the things around you are actually made of. It allows for the easy visualization of molecules in 3D, such as glucose, sulfuric acid, sodium carbonate, and hundreds more.

Google Science Journal

Google LLC

The kind of app that you wouldn’t think to look for but is such an incredible app that you wonder how its not more well publicized.

You can then export that data to a .csv file. There’s too much to explain in this space, you have to see it for yourself.
