Władysław Tryliński (1878-1956) - Polish transportation engineer. He invented and patented (1935) a technology of road paving with hexagonal pre-cast concrete-stone blocks - nicknamed "trylinka" after his surname.

The production of blocks was started in Brest (now Belarus) in the 1930s. The blocks were used to pave roads in Brest and other towns near Brest. The road Kobrin - Pinsk was paved with "trylinka". The pavement was strong enough to withstand numerous tanks and various heavy laden vehicles during the devastating war from 1941 till 1944. This type appeared to be the strongest of other types, invented in the 1930s. In the course of road reconstruction in the recent decade most of the trylinka pavement was replaced by asphalt. Fortunately, it remained, so far, in the Brest Fortress, in Pinsk, Stolin and some other places of Brest region.
Two blocks of trylinka by the road - after the pavement was replaced by asphalt., Trylinka in the Brest Fortress, Trylinka in Sovietskaya Street, Stolin Trylinka in old park Stolin] Trylinka on the road Stolin-Pińsk

Has anyone mentioned Sławomir Skręta, and his crimes against humanity?
He has a lot to answer for.

Sznajd model - one of the most popular physical models of social interaction. This belongs to a new branch of science known as sociophysics.

Józef Sznajd and his daughter Katarzyna Sznajd-Weron invented this model around year 2000. It is roughly based on the Ising model of interacting spins in ferromagnetic lattices but it is applied to social settings: politics, elections, advertisement, opinion forming and influencing, etc. The model is becoming more and more popular, and there are many publications in this area as recent as 2011. Just google: Sznajd model.

The people:
Prof. dr. Józef Sznajd (b.1947), Institute of Low Temperature and Structure Research, Polish Academy of Sciences, Wrocław.
Dr hab. Katarzyna Sznajd-Weron (b.1971), Institute of Theoretical Physics, University of Wrocław

Introductory blog article: Push Me, Pull Me. How Peer Pressure Works Along Scientific Laws.

The website of Katarzyna Sznajd-Weron:
with pointers to her publications and to a bunch of easy conference lectures.

You may also try e-print publications, by googling "sznajd model". These articles are relatively easy to understand.
Try for example: "Sznajd model and its applications" by K. Sznajd-Weron, 2005,

[Specifically recommended for Gumishu, Ironside and all the people who think that Polish media is a king in forming political opinions. Actually not, this is only partially true. The model, its simulations and the real life comparisons, such as elections in Brazil, are quite interesting actually.]

Jerzy Rudlicki (1893-1977) was a Polish aerospace engineer who invented and in 1930 patented the V-tail, a.k.a. Butterfly tail (Polish patent# 15938) configuration for aircraft combining the ailerons and elevators in one system. See V-tail,
