My Father went Silent Key !

From complex mathematics to complex chemistry and physics knowledge, that was my Father !
A great engineer, a great friend. We built an entire country house, me and him only. We bounded together more than anyone can imagine !
A sudden heart stroke followed by 2 weeks of of sedation while stent correction was applied to his heart, sent a great man into oblivion. I will always remember my father teachings, I will always remember his way of being.
GOD rest you in peace Father !
