Things to do in Warsaw

Here is a selection of attractions you can find in Warsaw:

1) Visit Łazienki Park and listen to a Chopin Concert.

Łazienki Park is a beautiful park, which is one of the two summer residences of the Polish Kings. It is in a walking distance (about 20-minute walk) from the Plac Konstytucji/Śniadeckich street, where the conference takes place.

Here is the info from the official Lazienki Chopin Concerts website:

Feel invited to the 64th season of Chopin Concerts in the Royal Łazienki. Recitals at the foot of the Monument to Chopin will be held every Sunday at 12.00 and 16.00 from May to September. Hear pianists of worldwide renown, including outstanding musicians of the younger generation.

Upcoming Concerts:

9 July - 12.00 - Maria Korecka-Soszkowska, godz. 16.00 - Michelle Candotii (Italy)

16 July - 12.00 - Aleksandra Świgut, 16.00 - Łukasz Krupiński

23 July - 12.00 - Julia Kociuban, 16.00 - Kamil Pacholec

2) Walk through the Royal Trail - from Plac Trzech Krzyży (or even from the Łazienki Park), through Nowy Świat, Krakowskie Przedmieście, to the Old Town (Stare Miasto/Starówka). On the Royal Trail, pay attention to black marble benches. You can sit on them and listen to Chopin by pushing a button. Chopin's family lived at the premises of Warsaw University, at Krakowskie Przedmieście. In front of the University, on the other side of the road is a church, Kościół Świętego Krzyża, where Chopin's heart is kept. He requested to bring his heart to Warsaw, and his sister fulfilled his wish after a quite dramatic journey. The story of Chopin's heart is a fascinating on its own.

Recommended restaurants along the way:

- Restauracja Nowy Świat 44 ( which serves Polish regional dishes and spirits,

- Alewino ( is a gourmet restaurant with a talented chef and a wonderful selection of wines. If you want to be there and sit in their garden, you have to book in advance. The restaurant is on an expensive side, but it is perhaps the best price/quality ratio restaurant in Warsaw

- Freta 33 ( is a recommended restaurant at Stare Miasto. You can seat outside and enjoy the view of the New Town Square. Freta Street, where the restaurant is located, is the street where Maria Skłodowska, known worldwide as Marie Curie, was born and lived before she left Warsaw for Paris. The church complex on the opposite side of the New Town Square, in relation to Freta 33 restaurant, contains the school Marie Curie attended before going to the Sorbonne. You can also visit the Marie Curie Museum on Freta Street.

3) Visit Chopin's Museum -

4) Visit national Museum ( We recommend medieval section; in particular Faras frescoes

5) Visit Royal Castle at Plac Zamkowy. We recommend the Bellotto/Canaletto hall as these pictures were used to rebuilt Warsaw after it was flattened by the Germans in 1944. We also recommend seeing the Aquamarine Sceptre of King Stanisław August Poniatowski, the only remaining insignia of Royal Poland that survived all the Russian-German occupations.

6) Visit Warsaw Uprising Museum,

7) Visit Muzeum of Polish Jews,

8) Go to the top of the Pałac Kultury i Nauki,

9) Walk along the Vistula River from the Old Town as far south as you can. In the evening, visit the bars there.

10) Go to Praga district: visit Ząbkowska Street to see the authentic prewar (WWII) Warsaw.

Public lecture from Ask a Physicist series.

Aleksander Bogucki and Paweł Nurowski

Acoustic decaphonic piano – its mathematics, physics and sound

Tuesday, 11th July, 18:00, Faculty of Physics, University of Warsaw, Pasteura


The hero of this lecture, the decaphonic piano, is an acoustic concert hall instrument constructed on the demand of the world-famous jazz pianist Leszek Możdżer. The piano is decaphonic since it needs ten sounds only to play the entire octave, in contrast to the twelve sounds played in an octave by the usual piano. The new piano built by us has the ten-scale equal temperament musical tuning system, as opposed to the 12-scale equal temperament used by musicians in most Western music since the times of J. S. Bach.

The acoustic decaphonic piano was designed by: Aleksander Bogucki, a physicist from the Institute of Experimental Physics of the University of Warsaw, Paweł Nurowski, a mathematician from the Center for Theoretical Physics of the Polish Academy of Sciences, Andrzej Włodarczyk, a constructor and a restorer of historic pianos, and by Leszek Możdżer - the initiator of the project. The keyboard layout is due to Ryszard Mariański, the frame by Roman Galiński, acoustics by Sławomir Rosa; regulation, intonation and tuning by Jan Grzyska and Mirosław Mastalerz. As far as we know it is the first piano instrument of this kind in the world.

In this lecture, Aleksander Bogucki and Paweł Nurowski, the scientific designers of the piano, will explain technical difficulties, scientific obstacles, and aesthetic issues, which they had to overcome to create an actual physical implementation of the instrument.

People without a musical education are most welcome to the lecture. All the relevant scientific information needed to understand the innovative nature of the instrument and the motivations for creating it will be explained. In particular, we will explain the mathematical principles of various musical tuning systems used in the history of Western music, so that after the lecture everybody shall know what is Pythagorian tuning, just intonation, equal temperament, and how the tuning system of our instrument is related to these classical notions. We will try to argue that mathematics prefers the tuning system employed in the decaphonic piano. The sound of music played on an electronic piano using these various tuning systems will be presented and compared with each other during the lecture.

During the lecture, the physics of sound needed to understand the difficulties in creating a physical implementation of the instrument, will be explained and illustrated by several experiments designed by Aleksander Bogucki, Paweł Trautman and Andrzej Włodarczyk.

The actual implementation of the decaphonic piano, and live music played on the acoustic instrument, will be presented during a separate event, at a concert played by Leszek Możdżer, which will be held in the Concert Hall Nowa Miodowa in Warsaw on Thursday, July 13, 2023, at 19:00.

How to get to the Faculty of Physics, University of Warsaw?

Take a tram nr 15 from Plac Politechniki. Further details will be given on Thursday morning.
