Common questions

What does Mass and Motion cover?

Physics as a concept plus the experiment or observation that tests it. Fields and Concepts carry the explanation, Experiments & facilities cover the instruments doing the work, Results & debates follow what has been claimed and contested, and Learning & careers covers study and jobs. There is no separate news section, because new results appear inside Results & debates.

Is this written for physicists or for the rest of us?

For a reader who wants the concept explained properly rather than simplified into metaphor, without assuming a degree. Where a result needs mathematics to mean anything, the piece says so instead of pretending otherwise.

Where do the results come from?

From journals, preprint servers, laboratory announcements and named science publications, credited and linked in each piece. A finding is reported with the collaboration or paper that produced it named, and its significance is described as the source described it.

How do you deal with a claim that later falls apart?

By reporting it as provisional in the first place and correcting it afterwards. Preprints and conference results are labelled as such, and Results & debates exists because contested findings are normal in physics rather than embarrassing.

Who is credited on an article here?

Nobody by name. Pieces are written with automated assistance from the source material, and the journal or publication behind each one is credited in place of an author. Nobody here is presented as a physicist.

Are there analytics on the site?

None. No cookies, no analytics, no advertising and nothing loaded from a third-party host.
