"Earthbound labs occupy a periodically jerked frame — one with a rich derivative structure that free-fall frames lack entirely." The 4th Dialog #1: Cell Life & Wobbly Earthbound Reference Frames thecopernicanproject.org/4th-dialog/ #Physics #ReferenceFrames #Biophysics #TheCopernicanProject

Since #ReferenceFrames are germane to any measurement problem, have to nail down: 1) Special relativity - inertial reference frames 2) General relativity - any reference frame, including accelerating

📢 The Community of Interest on Geodetic Reference Frames – Europe is organizing the webinar “Quo Vadis Geodesy?” on Tuesday August 20th 2024 #Geodesy #ReferenceFrames un-ggim-europe.org/events/un-ggim…

@MikeHeights3 @0liviajulianna Facts: This country has been far right for centuries. #referenceframes How else can I help you?

*RoboDK Tips & Tricks*: The reference frame of an object can be aligned with respect to its own geometry. This allows moving the reference frame of an object to a location that can be identified in a real setup. Learn more ow.ly/45fu50IwZUp #robodk #referenceframes

*RoboDK Tips & Tricks*: Defining a reference frame properly allows you to adjust or move your programs to different lications without having to re-teach all your targets. Learn more ow.ly/R8Kf50ImeET #robodk #tipsandtricks #referenceframes #offlinesimulation #robotics

@Maanmittaus 'laitos NLS nicely visible @UNGGIMEurope. Finnish delegation @HeliUrsin @markkupoutanen. Markku gave a report on activities of the Geodetic Reference frame Working Group #geodesy #referenceframes. Nice to be back home from cold and rainy Brussels (+28C at Helsinki)

#EUREF 2019 symposium in Tallinn accepted new resolutions related on #referenceframes in Europe. Including recommendation on using RINEX v3 data format in #GNSS data delivery and publish of EVRF2019 height data. See you next year in Slovenia.

Arriving Tallinn for EUREF Governing board and EUREF symposium later this week. Expecting more than 110 participants. #EUREF #geodesy #referenceframes

The team working on the new #heightdatum #referenceframes have released three reports. Head over our website to download the reports so you can get the most out of @GeoscienceAus #positioning for the future program. frontiersi.com.au/next-generatio… @nich0lasBr0wn #geodesy
