Mirjam Bilker-Koivula ja Hannu Koivula seisovat julisteiden vieressä. Julisteissa kuvataan Putoamiskiihtyvyyden ja geodesian Pituuden kansallisia mittanormaalilaboratorioiden toiminta.
Tänään juhlittiin @vtt.fi MIKES:ssä 150 v. mittausyksikköjärjestelmää. Ohjelmassa esitelmiä metrologian historiasta, nykytoiminnasta ja tulevaisuuden näkymistä, sekä keskustelu metrologian alan koulutuksesta. @geohannu.bsky.social:n kanssa esittelimme @fgi-nls.bsky.social:n metrologian toimintaa.

Was queuing there today for more than two hours for security. Catched my flight literally at the last minute.

Same here. Maybe editors have winter holidays and thus finally time to look for reviewers?

Feel you. The Finnish Academy has put the deadline for proposals to their winter call to 8.1. Right after the Christmas holidays. They end 6.1.

Väisälä comparator box with white light source on table. Mirrors on the left to adjust the light beams. Chair for observer behind the table. Under roof surrounded by metal fence.
Mirror installed on concrete pillar. Outside in forest under a roof.
Today, we had open house at the Nummela standard baseline of #NLS-FGI. This autumn it was measured for the 17th time using the Väisälä comparator, based on white light interferometry. Still the most accurate distance measurement method in the world, since the 1940s. #geodesy #maanmittaus
