Spotkanie festiwalowe Stephen King Revisited: The Writer’s Life and Literary Universe Under Scrutiny

For five decades now, Stephen King has been popular among his Constant Readers around the world. Most of us have probably held at least one novel by the modern master of horror or watched a film adaptation of one of his works. Is it possible that one of the most prolific and widely read writers in the world still holds secrets from us? During the meeting, we will look at the author's literary profile, talk about lesser-known works and learn a handful of interesting facts from the author's life in order to dispel myths concerning this cult and legendary creator.

Spotkanie festiwalowe Ethnography of Communication as an approach to study political discourse: The case of Belarus

This lecture will focus on the theory of Ethnography of Communication, as well as on the intellectual roots of this approach to study culture and communication in social contexts. Based on the ongoing research project that is focused on the study of Russian-language political discourse in Belarus, you will see how this approach can be used to get important insights from public discussions of political events. We will talk about the ways Russian-language political discourse found in everyday interactions and public communication about politics contributes to the construction of meaning about politics and identity in modern-day Belarus. If time allows, we will also practice using the approach to analyze the actual discursive data.

Spotkanie festiwalowe Ancient Egyptian culture in the light of 'talking objects'

During the course of this lecture, the audience will have the opportunity to interact with copies of different objects from ancient Egypt.

The goal of this lecture is to introduce people to the concepts of ‘talking objects’ from ancient Egypt, that is the idea that all archaeological finds ‘speak for themselves’ if one lets them. The notion of how they could possibly ‘speak’ to ancient Egyptians will also be demonstrated through explaining the ancient settings of the objects.

Special attention will be paid to the material the objects are made out of, as these give a great detail of information about the intentions of Egyptians about the purpose of the objects.

Spotkanie festiwalowe Model Celebrity: The Elegant Nematode Caenorhabditis elegans

Caenorhabditis elegans is a small (up to 1 mm in length), non-parasitic nematode living in soil. Several features of this nematode have contributed to its status as one of the most popular model organisms. The transparent body of C. elegans significantly facilitates microscopic observation of all its 959 somatic cells. One-third of all the nematode's cells are neurons. It is the only organism so far with a complete map of neural connections. The nematode's life cycle is very fast—development from egg to adult takes about 72 hours. Over the next 3 days, a single individual can lay up to 400 eggs, which greatly simplifies the process of obtaining large populations for research purposes. C. elegans was the first multicellular organism to have its entire DNA nucleotide sequence read. The nematode genome contains many genes that have counterparts in humans. Because mutations in many of these genes result in the development of serious diseases in humans, the nematode is used as a model for many diseases.

The meeting will consist of a lecture and a practical part. Participants will be introduced to basic information about nematodes: their structure, life cycle, and physiology. An overview of the main scientific discoveries made using nematodes and the most interesting directions for future research will be presented. During the practical session, participants will learn basic techniques for working with nematodes, conduct observations using fluorescence microscopy, become familiar with the basics of classical (Mendelian) genetics, and learn the genotyping method using polymerase chain reaction (PCR).

Spotkanie festiwalowe The Significance of Contemporary Tattoos: Identity, Fashion, and Body Aesthetics

Tattoos, with a history that spans back to the Prehistory of humanity, continue to hold significant cultural meanings in our contemporary society, making them a relevant and engaging topic of study. Tattoos today, therefore, involve combining both elements of traditional non-Western ritual practices and current artistic Western trends. In this presentation, we discuss the popularity of tattoos in urban settings, which has developed into a global tattoo culture. Drawing on an anthropological comparative analysis between tattoo artists in Mexico and Europe, the presentation describes the creative process of tattooing from the artist’s perspective and the growing acceptance of inked bodies in society. It also discusses the meaning of tattoos as fashion and aesthetic identity statements and the performative aspect of getting a tattoo as a meaningful, semi-ritual, intense experience. Finally, the presentation discusses the importance of tattoo conventions and social media as infrastructural platforms in helping share knowledge and build social relations among artists and clients.

Spotkanie festiwalowe A unifying concept in physics: Reciprocity

In physics, we have many different branches. For example, the theory of elasticity, thermodynamics, quantum mechanics and general relativity are all constructed on different mathematical and physical frameworks. They apply to different scales and they refer to different mechanisms that explain our physical world. In this talk, I will refer to a concept which applies to all of the aforementioned branches of physics. This common property is called “reciprocity”. Loosely speaking, it refers to the fact that the measurement outcome of a system does not change when the input and the output variables are exchanged. Although it might seem trivial at a first glance, this property signals an important feature of linear systems. Being a relativist, I will mostly focus on the reciprocity theorem of distances in the context of cosmology. We will explore what this means for the current data analysis for observations on the sky.

Lekcja festiwalowa Clash of the Titans: Monster Earthquakes in Hidden Battlegrounds!

Calling all earthquake explorers! Have you ever wondered about subduction zones or collision zones? These are hidden battlegrounds deep within the Earth, where immense forces create the largest earthquakes ever recorded. In this one-hour adventure, we'll embark on a journey to the Earth's interior to discover the secrets of these zones. We'll learn how giant slabs of rock collide and grind together, unleashing monstrous earthquakes. We'll even see how scientists track these powerful events and what we can do to stay safe during an earthquake. Buckle up, junior seismologists, this is going to be an epic earthquake exploration!

Imagine Earth's crust as a giant puzzle. Subduction zones are like the areas where one giant piece of crust is pushed beneath another. This constant pressure creates immense forces, which can trigger powerful earthquakes. I am like an earthquake detective, but instead of fingerprints, I analyze data from earthquakes around the world. I'm particularly interested in a theory called the "asperity model." This theory suggests that some parts of the subduction zone are bumpier and get stuck more easily, causing even stronger earthquakes! By comparing data from different earthquakes, I can help you understand how these giants work and potentially improve earthquake prediction in the future.

Venkata Kambala: I am a Ph.D. student (or Doctoral Student) in the Department of Theoretical Geophysics at the Institute of Geophysics, Polish Academy of Sciences (IGF-PAN), in Warsaw, Poland. I am on a mission to unravel the mysteries of giant earthquakes! My primary focus is on a specific type of earthquake that occurs near ocean edges, in regions called subduction zones.

imaginative narratives dive into advanced technologies, societal transformations, and ethical dilemmas. Visionaries like Tom Lombardo see it as a guide to the future, preparing
us for incredible changes ahead. In contrast, Ursula K. Le Guin believes sci-fi's true power lies in its ability to mirror our current reality, using fantastical stories to shed light on
today's issues. Together, these perspectives show that science fiction is not just about distant worlds and future tech but about understanding our human experience and societal
evolution. It is a genre that invites readers to think deeply, dream big, and see the world in new and exciting ways.

Makbet Williama Szekspira jest jedną z najsłynniejszych tragedii angielskiego dramatopisarza, regularnie przenoszoną w różnej formie na ekrany kin i telewizji. Jest też doskonałym przykładem tego, jak wielorakie artystyczne wizje autorów szekspirowskich adaptacji oraz ich interpretacje wydarzeń i postaci przedstawionych w oryginalnych sztukach pozwalają rozszerzyć przekaz każdej z nich o dodatkowe wątki, elementy i konteksty, trafiając tym samym do kolejnych pokoleń odbiorców. Podczas wykładu uczestnicy będą mogli zapoznać się ze sposobami tworzenia adaptacji dzieł scenicznych na potrzeby innego medium, jak np. filmu, telewizji czy animacji oraz w jaki sposób i w jakim celu dana wizja reżysera modyfikuje lub odwraca znaczenia obecne w oryginalnym tekście sztuki. Na przykładach analizowanych adaptacji szekspirowskich uczestnicy poznają techniki i rozwiązania stosowane przez twórców w trakcie dostosowywania dzieła scenicznego do nowej formy przekazu oraz wprowadzania ich własnej wizji i interpretacji oryginalnego tekstu. Przybliżone będą też wybrane konwencje i techniki adaptacyjne, np. transpozycja czy amplifikacja, formy ich zastosowania oraz efekty interpretacyjne. Przedstawione będą też konsekwencje takich ingerencji, zarówno pozytywnie jak i negatywnie wpływające na oryginalny przekaz dzieła.

Lekcja festiwalowa A journey to the beginning of the Universe and back

Our Universe is a factory of mysterious and sometimes inexplicable phenomena. Since the dawn of human kind, astronomers have wondered about the nature of the cosmos, first looking at close and bright planets and comets in our solar neighborhood, up to the faintest and more distant galaxies at the beginning of time.
In the last century, we experienced a revolution in the study of the Universe thanks to the joint efforts of worldwide organizations which gathered astronomers, engineers, and physicists together to build and develop new tools and techniques for the exploration of the outer space in all its aspects. Starting from Galileo Galilei’s “spyglass”, we designed and built increasingly powerful telescopes to observe not only the visible light emitted by distant stars and galaxies, but also a wide range of frequencies invisible to our eyes, opening a new window on the dark side of the cosmos. Sometimes these instruments are set in very wild environments and extreme conditions, like in the arid and desert lands of Chile, in the coldest and icy region of Antarctica, or even outside the earth’s atmosphere. Astronomers try to put together the different pieces of information from each of these telescopes, with the common aim of obtaining a comprehensive understanding of how the Universe began and evolved.
We will unveil the secrets of galaxies in the early Universe and show how they grew and died. You will interactively learn how to classify the shape of previously unseen galaxies, and to use the principles of physics to magnify the light emitted from them. You will also have the unique chance to personally meet professional astronomers, asking them questions about their life and work in a friendly and informal environment.

Spotkanie festiwalowe Her Majesty Symmetry: Symmetry and Order, Phases of Matter, and Phase Transitions

The role of symmetry in the Universe, our life, and in physics is so versatile that one must deal with a particular area. I address the role of symmetry in the physics of macroscopic phases of matter and their transformations called phase transitions. Bodies with very different molecules often represent the same phase of matter because, actually, a macroscopic phase is determined only by its symmetry.Many fundamental effects of phase transition can be predicted considering the symmetry alone, making the calculations involved very simple. Depending on the symmetry of macroscopic phases, the transformation between them, a phase transition, can be of two different kinds. The second order phase transition occurs in bodies with the so-called polar symmetry. This transition is also described as a spontaneous symmetry breaking of the original phase. The common example of polar order is a magnet with molecules bearing magnetic moments (small magnets). The transition from the isotropic (all molecular magnets are oriented chaotically making no macromagnet) to the polar (ferromagnetic) phase occurs when the temperature decreases to the so-called Curie temperature Tc and the energy prevails over entropy. The very important property of this second order transition is that the two phases, the nonmagnetic and magnetic, cannot coexist, i.e., the body is either magnet (below Tc) or non-magnet (above Tc). The first order phase transition occurs in a body with the non-polar symmetry. The common example is a nematic liquid crystal, which has been used as a working optical element in the cell-phone and computer displays. A nematic liquid crystal consists of elongated molecules. When these molecules are oriented chaotically, the liquid is isotropic (dark when seen in a microscope). As the temperature decreases to certain value TNI, the molecules get oriented along single direction called director; such liquid is an anisotropic nematic liquid crystal (colors appear!).The order is non-polar as both directions along the director are indistinguishable. The benchmark of this transition (which is similar to the water-ice transition) is that the two phases, nematic and isotropic (ice and water) can coexist in some narrow temperature interval. The second and first order transitions are very different, but the whole difference is solely in the symmetry of the phase of matter. Thus, the main effects can be predicted without any calculations because only Her Majesty Symmetry rules them.

Spotkanie festiwalowe Sound Waves and Lenses to Explore the Dark Side of the Universe

Imagine a universe where most of what exists is invisible, dominated by an unseen force driving its expansion and an unseen form of matter shaping the structures. Well, that is precisely what we think our Universe looks like. Join us for an informal discussion of what evidence we have to support this idea.

The story begins with galaxies that rotate faster than they should, hinting at an invisible mass providing extra gravitational pull. As we explore further, we find galaxy clusters that don't have enough visible matter to hold them together, implying a mysterious hidden substance. This invisible mass, known as dark matter, becomes even more evident when we observe how light from distant objects bends around such massive objects.

Our journey continues with the ripples created by sound waves moving through the early universe. These ripples help us understand the composition and proportions of our universe. They can be observed in the typical separation between galaxies and in the cosmic microwave background (CMB), a remnant from the early universe. This is the oldest light we can observe. Minor temperature fluctuations in this light help us understand the distribution of matter after the Big Bang. These patterns suggest that dark matter played a significant role in forming the galaxies and structures we see today.

Pieced together, these different probes support our understanding of how dark matter shapes the universe. Whether you're an avid astronomy fan or just curious about the cosmos, this talk will reveal the fascinating techniques scientists use to uncover the dark side of the cosmos.
