Non-Euclidean Geometry...and a big thought for Houston !

Activity: 
Gruppsamling

All our thoughts were about Houston and the storm these days...
We found old photographs of NASA engineers and mathematicians (you rock guys !) and saw the movie "Hidden Figures" (we love you Katherine Johnson, Dorothy Vaughan and Mary Jackson !).
We take advantage of these first days of September to test the Lénárt sphere that we have just received of Hungary, and do some optics.
Beautiful mathematics in perspective ;-)
See you soon, and don't forget to register.
