This is the laboratory notebook of the PHL, a preprint and technical blog space of ideas and progress reports that could be later incorporated into peer-review research. Its content is mostly oriented to scientists, specially to those involved in our projects. However, many of the entries contain links to images and software that could be of interest to the general scientific community, educators, and public. You can subscribe to it via RSS.
