Title: Potential Applications of Negative Radiation Pressure in Astronomy, Medicine and 2WQC Date: April 19 2026 10:00 am - Noon EDT (16:00 - 18:00 CET) Abstract: While we are used to heating and pushing with light, there is also optical cooling and pulling. I will talk about negative radiation pressure, potential ways to generate it, and its novel applications, like non-ionizing medical scanners, 2WQC (two-way quantum computers) in theory solving NP problems, also potential astronomical sources and their observation. Speaker: Dr Jarek Duda is an assistant professor at Jagiellonian University. He holds degrees in computer science (PhD), mathematics (MSc) and physics (PhD). He is mainly focused on physics foundations, information theory, statistical analysis, and is known for introduction of asymmetric numeral systems.

Capoeira (capo-way-ra) is an Afro-Brazilian martial art that is unlike any other martial art. Capoeira incorporates flowing movements with kicks, dodges, and some acrobatics. It is often mistaken for a dance for those reasons. Since it’s origins in the 17th century, it has evolved from a secret fighting practice into an art emphasizing self-expression and community celebration. It is great for the body and mind! In addition to gaining strength and flexibility in class, students learn about Brazilian culture, history, and language (Portuguese). On November 26, 2014 capoeira was granted a special protected status as "intangible cultural heritage” by UNESCO. No need to have a Capoeira background to join this class, just an open mind to try out a new way to move! Beginners welcome. **Please reserve your spot at www.piesfitnessyoga.com**.

Learn to manage stress and achieve self-growth through simple relaxation and Meditation. Heartfulness Meditation is a simple, modern, methodical approach to meditation. Rather than homing in on your breath or repeating a mantra, you simply focus inward, on your heart, to cultivate inner strength and serenity. Heartfulness meditation is gaining traction in recent years. It focuses on the heart, allowing individuals to connect with themselves on a deeper level, and ultimately achieve peace, relaxation, and clarity. It is a practice that encourages patience, self-compassion, and acceptance, helping cultivate a deeper appreciation for the present moment. This practice is offered with love and at no cost

THIS CLASS IS OFFERED THROUGH CAPITAL PHOTOGRAPHY CENTER **PLEASE REGISTER WITH CAPITAL PHOTOGRAPHY CENTER, NOT MEETUP!** https://capitalphotographycenter.com/classes/class/2026-04-19-sculpting-photos **Sculpting Photos** The sculptures in the west wing National Gallery of Art offers photographers a unique creative challenge: The art is already shaped by light, form, and intention. In this class we will explore how photography can re-imagine three-dimensional works through thoughtful observation and creative choices. By paying close attention to light, shadow, texture, and perspective, photographers can reveal new interpretations of sculptures, highlighting details, moods, and relationships that may not be immediately visible to the naked eye. Through guided looking and hands-on practice in the galleries, students will learn how camera position, framing, depth of field, and timing transform solid, static objects into dynamic photographic images. Whether isolating a gesture, emphasizing scale, or experimenting with abstraction, this class encourages photographers to move beyond documentation and toward personal expression, using sculpture as a powerful starting point for visual storytelling. Whether you’re new to photography or looking to deepen your practice, this class invites you to see the sculpture and your creative process in fresh ways. In this class you will learn to: 1. Develop observational skills by learning to analyze sculpture in terms of form, space, light, and texture, and translating those observations into intentional photographic choices. 2. Explore creative photographic techniques such as framing, perspective, and selective focus to reinterpret sculptures and create expressive, original images in an indoor museum setting. 3. Build visual storytelling skills by using photography to convey mood, movement, or meaning, helping students articulate a personal response to sculptural works. All cameras are welcome, from your smartphone to DSLR. However, we recommend the camera you use has multiple lenses or a zoom, and ability to adjust exposure. Lenses in the range of 28mm to 200mm would be appropriate. No flash or tripod since we'll be in a museum. Questions can be directed to Marie Joabar at info@capitalphotographycenter.com. Class limit: 8-9 *** **THIS CLASS IS OFFERED THROUGH CAPITAL PHOTOGRAPHY CENTER** https://capitalphotographycenter.com/classes/class/2026-04-19-sculpting-photos
