Video call with Pippa this evening. She has turned 18 and already back in Groningen. Her day filled with lectures, tutorials and training.
The diagram on the right is a Hertzsprung Russel diagram. As part of her introduction to astronomy subject she had to explain one part of the syllabus to a non astronomer (me). She did a great job and was able to answer all my questions.
So proud of my girl!
