You may have heard friends say, “Oh, no – Mercury is about to retrograde again!” If you don’t know astrology, you may have wondered what they were talking about. Of all planetary aspects, this one seems to garner the most attention from readers, and it certainly generates the most mail. The reason for their interest is clear – this phenomenon is one of the few that affects everyone in a fairly uniform way, and its effects are always obvious. Once you begin to pay attention to how events in your life change during these phases, you will soon see how important it is to take note of them. Keeping track of Mercury retrograde periods can allow you to increase your productivity and avoid at least some of the frustration they can bring about. This API serves JSON over HTTPs. It allows you to determine whether Mercury is in retrograde for a given date.

The OSF serves as a repository and archive for study designs, materials, data, manuscripts, or anything else associated with your research during the research process. Every project and file on the OSF has a permanent unique identifier, and every registration (a permanent, time-stamped version of your projects and files) can be assigned a DOI. You can use the OSF to measure your impact by monitoring the traffic to projects and files you make public. With the OSF you have full control of what parts of your research are public and what remains private.
