Fourteen symposia on early/lower vertebrates have taken place over the last 50 years, usually at about four year intervals. An average 60 participants have taken part at these symposia, with over one hundred occasionally. The results of the symposia have been published in proceedings. The symposia started honoring E. A:son Stensiö and E. Jarvik. Honors were taken up at the 11th symposium in Uppsala again. Since the 13th symposium a Stensiö award is also given to young researchers in the field.
School textbooks written by a Spanish erudite and pedagogue Juan Luis Vives were used in schools of Protestant denominations in Royal Prussia – in Gdańsk, Toruń, Elbląg, but also in other towns and cities of the Polish-Lithuanian Commonwealth– for teaching Latin. Nicolaus Volckmar, of German descent, a Polis language teacher at the Academic Gymnasium in Gdańsk, utilized the structure and themes of Vives’ dialogues Exercitatio linguae latinae (1538) for teaching the Polish language. In this manner, paradoxically, the “phrasebook” of the Spanish humanist, as well as its subsequent editions, still in the 18th century was used by Gdańsk schoolers of German origin to learn the language which they needed for everyday communication in the community of multi-cultural and multi-ethnic Gdańsk. The Vives-Volckmar phrasebook was undoubtedly used by Arnold von Holten, later a lifetime mayor of the city, sent on a diplomatic mission to Spain by the Hanseatic League.
WILGA annual symposium on advanced photonic and electronic systems has been organized by young scientist for young scientists since two decades. It traditionally gathers around 400 young researchers and their tutors. Ph.D students and graduates present their recent achievements during well attended oral sessions. Wilga is a very good digest of Ph.D. works carried out at technical universities in electronics and photonics, as well as information sciences throughout Poland and some neighboring countries. Publishing patronage over Wilga keep Elektronika technical journal by SEP, IJET and Proceedings of SPIE. The latter world editorial series publishes annually more than 200 papers from Wilga. Wilga 2018 was the XLII edition of this meeting. The following topical tracks were distinguished: photonics, electronics, information technologies and system research. The article is a digest of some chosen works presented during Wilga 2018 symposium. WILGA 2017 works were published in Proc. SPIE vol.10445. WILGA 2018 works were published in Proc. SPIE vol.10808.
