I was borne in Sweden and moved to Brazil 1993 and since then been active here. Almost everyday I do Science and teach students at various levels. From graduation to PDs. The reason for this is to transfer to them what I have learned and by this make them independent. It is also to learn from them, what is still to be learned. If there is anything :-) This create and interesting atmosphere, where little is taken for granted and hopefully create future knowledge-hungry Paradigm-Crusher.
