1) A Message from the IMI Director
Dear Colleagues,
It is a pleasure to inform you that Mihaela Negreanu Pruna, IMI member, is a new Professor (Catedrática) at the Department of Applied Mathematics and Mathematical Analysis at Complutense University of Madrid since 11 March 2024.
Mihaela Negreanu Pruna
Congratulations Mihaela!
Ángel Manuel Ramos del Olmo
22 April 2024. The MOMAT research group obtains funding for a European M-ERA.NET research project. The title is Sustainable High-Voltage Batteries Based on Hybrid Cathodes Enabling Dual-Ion Energy Storage and it will be developed during 3 years together with a consortium of several research groups from different European countries. J.A. Infante, B. Ivorra and A. M. Ramos (members of IMI and MOMAT) will participate in the project.

7) Math Puzzle
Puzzle sent by Kjartan Poskitt.
The solution will be provided in the next issue of Boletin del IMI.
Solution to last week's Math Puzzle, sent by Rik Tangerman and published on issue No. 128 of the Boletín del IMI:
The tympanum
The angle α is 108°.
First, extend the extended side the other way to where it meets the perpendicular line AI in H. It is known that in the regular pentagon angles ACI and ICH both are 36°, implying that |AI|=|IH|. This in turn implies that |AF|=|FH|.
Now we can draw the circle centred in F through A, G and H. Angle AHG is easily found to be 54°, making the angle α at the centre twice that.
