In 1671, Jean Richer was the first to observe that earth’s gravity was not uniform. Isaac Newton later drew the obvious conclusion. #Poetry #Science #History #Gravimetry #Richer #Newton (https://sharpgiving.com/thebookofscience/items/p1671c.html)

We're looking for a new #PhD colleague for our 10m #AtomInterferometry facility in Hannover, Germany! If you want to work on something BIG (literally), come join us!
#Quantum #Gravimetry #Physics
https://qoto.org/@quantumsensing/109518491507551529

And to put things into a longer term perspective here is the #GRACE + #GRACEFO satellite record showing the last 20 years of #gravimetry data.
@greenlandicesheet has lost #ice basically every single year..

This is also shown on the #PolarPortal

Sharing this again, because it has recently been illustrated with a few new photos:

I gave a short interview to explain why we are building the #VLBAI - a 10m high free fall tower for #UltracoldAtoms and #AtomInterferometry. I talked about how this works, why this is interesting for #Gravimetry, and what kind of challenges we need to overcome!

Today, I gave a lab tour of our #VLBAI (Very Long Baseline #AtomInterferometry) facility to a class of high school students!
Their teacher was really enthusiastic, but I felt like talking to a wall of bored faces for the students - but then they asked quite a few clever questions ;)

I hope they went home with some idea how #Gravimetry with #QuantumSensors works and why Bose-Einstein condensates are cool (literally)!

[I also brought my new lab assistant to the tour]

After the German government approved funding of the #GRACE-I mission recently, yesterday the #ESA Council at Ministerial Level gave green light for the #MAGIC double-pair mission. Fantastic news & exciting times for #geodesy and satellite #gravimetry!
