My objective is to transmit my thoughts, my experiences, my scientific fantasies... for that, come and participate to a journey around science. The fields of knowledge are marked out by my doctorates: Speciality organic chemistry; physical sciences, pharmaceutical sciences from where the circuits through: the drugs, the ecology, energies, education, health... Rational or passionate communication was inspired by the work of Lucien Israël. All citizens who wish to get out of the rut of the single thought, can accompany me in this very free stroll. The inconvenient truths come from my perceptions; often skeptical, sometimes critical, but rather constructive. The language is accessible to most people, because even in science, what is well conceived is clearly stated... So come with me if you have a few hours for this sharing, giving free rein to the imagination. Like Einstein, we must think that imagination is more important than knowledge! But the right hemisphere opens the door to manipulators... Patience Effort confidence our leitmotiv!
