Reach the lab.
One address handles methodology questions, replication requests, corrections, and collaboration. Substantive messages receive substantive replies. We read everything, even if we don't respond to all of it.
Methodology questions
If a calculation choice in a published note seems wrong, write to us. Include the post URL and the specific equation or parameter you're asking about. We treat methodology challenges as collaboration, not criticism.
Replication requests
If you want to replicate a published study or reconstruction, write with your stated purpose and we will share the underlying parameters, scripts, and (where applicable) anonymised data.
Corrections
If you spot an error (arithmetic, dating, attribution, citation), please write. Corrections to existing posts are noted in place with a dated revision line. We do not silently fix things.
Collaboration
If you work in astronomy, statistics, history of science, or computational science and want to collaborate on a specific reconstruction or analysis, we are open. Send a paragraph on what you have in mind.
We don't use a contact form. Direct email is the lowest-friction, highest-signal channel and it keeps the conversation portable. We don't use analytics on this page. We don't share addresses with anyone. We don't send promotional content.
