Quantum Algorithms

This month we have a fantastic session hosted by James Birnie, Director of Strategic Consultancy at **[Forrow](https://forrow.uk/)** where he will talk about how to get post quantum ready. In this talk James will discuss why all the world's encryption will break, why a lot of your data is leaking right now, what you need to do now and what you will need to do in the near future. **About James Birnie** James Birnie has worked in software delivery since the 1990s, when TDD was something you studied but never did, "agile" and "lean" were words used to describe athletes, and Pipelines were for carrying oil. James worked in a successful startup for 10 years before he became a consultant (and an ex software engineer) at, first, Thoughtworks and then Codurance. After time as Head of Platform at Currencycloud and VP of Engineering at IMMO Capital, James returned to consultancy and is currently Director of Strategic Consultancy at Forrow. He mainly spends his time trying to keep organisations secure against current and future threats, including the immediate threat of Harvest Now Decrypt Later attacks. **Food and Drinks** Pizza and drinks will be provided upon arrival sponsored by **[Codurance](https://www.codurance.com/),** with vegetarian and vegan options available.

Hello there! - We'd like to welcome you to Free weekly meetings hosted by Shalini & Manitu which take place at the: Greenwich West Community & Arts Centre, 141 Greenwich High Rd, SE10 8JA, on Thursday evenings from 7.30pm until 9.00pm With Sahaja Yoga Meditation we normally sit on chairs to achieve yoga, effortlessly & spontaneously. So there is no need for mats and no special clothing required. All across the globe, many are seeking new sources of energy. Meanwhile, the most transformative energy of all is hiding in plain sight, within us. It's natural, sustainable, and infinitely renewable. It's called inner kundalini energy. And everyone already has it — everyone!. It is often likened to an inner feminine or motherly energy which automatically knows about us and what is needed to help us restore balance and harmony within our subtle being. It works spontaneously, effortlessly, organically and cannot be paid for. Sahaja Yoga Meditation is a simple time-honoured technique that lets you tap into that energy and harness its power to become better balanced and better connected to yourself — emotionally, physically, mentally and spiritually If you're having trouble juggling the challenges in your life, Sahaja Yoga Meditation might well help you manage stress, master your emotions and find solutions to your problems . You may enjoy better health, better focus, and a deeper understanding of the universe and your place in it. Meditation is not just for mystics and monks. Sahaja Yoga meditation is for everyone. Anyone can do it. It's that easy. But with the Sahaja Yoga experience, you'll quickly realise, it isn't your typical Meditations 'R Us type class. It's much more than just feeling peaceful and relaxed. Sahaja Yoga Meditation has many layers, varied and deep. Explore at your own pace, in your own way. Our volunteer experts are always available to help. Ready to plug into your inner energy? A Sahaja Yoga Meditation class is a great way to start. A few minutes of your life may be all it takes to connect to your inner energy and light the path to lifelong transformation. Sahaja Yoga is more than a temporary solution or quick relief — it is a journey, rather than a destination. It's all about energy — guaranteed pure and carbon neutral. You can never have too much of it. The best part? All classes are free. No strings, no catch. Everyone is welcome. Bring a friend, bring your self — all are welcome. We have a web site here in London too which you can visit for more info about weekly meetings: www.sahajayogalondon.co.uk (http://www.sahajayogalondon.co.uk/) Join us on Facebook (https://www.facebook.com/London.Free.Meditation) and Twitter (https://twitter.com/SahajL)

**😍😍🎶 Sunday 03/05: VICTORIA OLIVELLA’S Welcome Milonga + Live Music QUANTUM ENSEMBLE** We are so honoured to welcome, this spring, the **Worldwide Tango Salon Vice Champion VICTORIA OLIVELLA** (Buenos Aires), who will be teaching at Los Angelitos an exclusive class, and celebrate at her Welcome Milonga with the **Live Music of QUANTUM TANGO**. Victoria Olivella is an Argentine tango dancer and teacher recognised for her elegance, musicality, and strong technical foundation. She gained international attention as the World Vice Champion of Tango in 2022, a title that established her among the leading figures of the contemporary tango scene. She came so close to being world champion – at this level, the difference between sub-champion and world champion is infinitesimal ;-). Known for her refined style and expressive interpretation, Olivella performs and teaches at festivals and events across Europe and beyond, often partnering with renowned dancers. Her teaching is especially appreciated for being clear, warm, and practical, focusing on technique, connection, and musical awareness developed through years of experience. You will find her teaching impressively warm and useful, giving tips that she developed in her dancing along the years. Don’t miss this opportunity to learn from the best tango has to offer. **🤩🤩 PROGRAMME:** Victoria will teach with Bruno both classes. We will start with he beginner / improver lesson on the theme of the Ocho Atras, and follow with the 3pm Fabulous Volcadas: learn the tricks and technique from a vice champion to make your Volcadas to die for – well not that far but almost ;-). Your milonga Los Angelitos will follow, for all to enjoy, with Live music and a TDJ. What a feast! * **[https://tanguito.co.uk/sunday/](https://tanguito.co.uk/sunday/)**

A Rabble session is 1 hour of fun and social team games. Each game disguises high-intensity intervals within the rules, giving you an effective, all-body workout without even realising it. We play a bunch of different games at each session (like British Bulldog, Capture the Flag, Dodgeball, Frisbee and many more), and every class is different. Sessions are open to all, no matter your sporting ability. Each game is explained before we start, so there's no need to have played any of the games before. Come solo or bring friends! And stay at the end for the social part! Who knew getting fit could be this fun? **TO BOOK**: It's essential that you book onto sessions via our website, using the link below; due to restrictions on games and preparation times we cannot accept walk-ins, or late arrivals.

DANCING EVERY 1ST AND 3RD SATURDAYS OF THE MONTH <3 Tribalheart Ecstatic dance creates space for free-form movement in a chat free zone where you can dive deeply into the heart, reconnecting, expressing, dancing in and out, up and down, learning to let go of anything and everything that holds you back from yourSelf and inner freedom. Let the energy move you, let the spirit of the heart guide you. There is space to dance alone and no pressure to connect with anyone else, just be yourself and honour what you need in the moment. This night is an inspiration and fusion of club culture, dancing yoga, active meditation, cardio fitness, Ecstatic trance dance (blindfolds available) and a sacred Nataraj. If you choose to connect, it is a chance to meet others without words from a place of movement, meditation, energy and soul; eyes and heart wide open. ### We will start the evening with a welcoming warmup to relax the body and mind. Together we will set an intention for the evening inviting the heart to open and awaken within us thus creating sacred space for all. For those that wish to partake, we will enjoy and deepen our intention with a short Cacao ceremony. (The cacao is used to take us deeper into our body, awakening our senses, connecting us to heart energy and aiding a spring in our step) We also embark on some dynamic breathwork to fire us up for the evening. \- Please leave at least 2 hours after eating a heavy meal if drinking cacao\. -Please do not drink alcohol before the event as it is contraindicated with some of the breathwork techniques we practice We inject passion into sourcing the music for our events and aim to deliver an eclectic mix of genres for your heart. From tribal to electronic and everything in between we aim to assist a natural flow peaking and resting to mirror the rhythm and energy of life. Prepare to shake, spin, whirl and twirl. The music becomes the facilitator during the wild ecstatic dance ending with moments of stillness into silence where we can rest and breathe together Each DJ has their own sound and energy to be shared, making each night unique and different... 4/4/2026-DJ TARA 18/4/2026-DJ ATMO Admission **New Venue**-Doors open from 630pm and we start at 7pm.

**Caller: Richard Ades** **Band: The McKenzies** **Clinton Heights Lutheran Church** **15 Clinton Heights Ave, Columbus, OH 43202** WHAT IS CONTRA DANCING? Picture the Grand Ball scenes like you’ve seen in period films such as “Pride and Prejudice”, where the dancers are lined up in long lines, across from each other. That’s English Country Dancing, the predecessor of contra dancing. Now, add moves like “swing your partner” and “do-si-do,” like you’ve seen in square dancing. Set it to fabulous, high energy, live music with fiddles, guitars, percussion and more, alá “Riverdance.” Finally, set the whole scene down in the middle of Woodstock, with a hip, groovy atmosphere, a bit of tie-dye, and hints of counter-culture attitude. THAT’s Contra Dancing! Wear cool and comfortable clothes (you will get warm) and clean shoes that won't mark up our nice wood floor. Be sure to come for the beginner's lesson from 7:30 - 8:00, followed by dancing 8:00 - 10:30. All dances are taught; we will help you learn! Beginners always welcome, no need to bring a partner. Cost is $10.00 adults, $5.00 ages 12-26. Under 12 free. Free parking in church lot. For more information contact me or check out our website: [www.bigscioty.com](http://www.bigscioty.com/) Please bring your own refillable water bottle.
