THIS CLASS IS OFFERED THROUGH CAPITAL PHOTOGRAPHY CENTER
**PLEASE REGISTER WITH CAPITAL PHOTOGRAPHY CENTER, NOT MEETUP!**
https://capitalphotographycenter.com/classes/class/2026-06-07-iphone-photography
Learn to use the iPhone camera and the settings for creative image captures. Join Michael Koren at the National Gallery of Art and learn techniques for exposure, composition and focus. Tap into your creative side through smartphone photography.
Using our iPhone cameras, we’ll explore the Museum's offerings from abstract sculptures, colorful paintings and wall hangings, to the architecture of the building as well. We’ll find endless photographic opportunities perfect for iPhone photography.
We’ll start with the basics of learning to use the iPhone camera and review the settings for optimal image capture to pro tips and techniques that produce the best results.
The number of photography apps available seems endless and can be very confusing when trying to choose what to purchase. Michael will cover one of the most exciting apps for image processing so you can achieve your artistic vision.
This class is designed for users of iOS mobile devices. The app info will be included in your confirmation letter (the app is free).
Topics include:
• Proper techniques and settings for iPhone image capture
• Tips and techniques for using the iPhone’s native camera
• Learn exciting editing tools
• Hands-on capture and editing
• Image critique and feedback
For more information about the Gallery, visit their website, https://www.nga.gov/index.html
Participants will need to bring a fully charged iPhone. A charger is a good idea too as photos quickly drain the batteries.

Machine Learning for Reliable Quantum Computing: An Algorithm–Hardware
Date: June 7 2026 Sunday 10:00 am - Noon EDT
Full title: Machine Learning for Reliable Quantum Computing: An Algorithm–Hardware Co-Design Perspective
Summary: Reliable quantum computing requires co-design across the full stack, including algorithm structure, compilation, and execution, rather than isolated optimization of any single layer. This talk presents a unified framework in which these layers are jointly optimized under realistic hardware constraints. Structure-aware compilation exploits algorithmic interaction graphs to reduce circuit depth; joint optimization across mapping, term ordering, and algorithm parameters yields significantly improved success probability; and execution-layer analysis reveals that error mitigation effectiveness depends critically on circuit symmetry and native gate choice. While demonstrated on superconducting quantum processors, the underlying co-design principles are potentially transferable across architectures. Building on this foundation, the talk highlights machine learning as the key enabler for closing the feedback loop: data-efficient, parameterized noise models learned directly from workload execution data achieve substantially improved predictive fidelity over vendor models without the overhead of dedicated characterization. These insights situate the co-design perspective within the emerging framework of quantum deep learning. In this broader setting, the talk also presents an operational definition, a unifying taxonomy, and a benchmarking protocol grounded in explicit resource contracts.
Speaker: Dr. Yanjun Ji has an interdisciplinary research background in Physics and Computer Science. In 2020, she completed my Master's degree in Theoretical Physics at Saarland University. In 2024, she earned her Ph.D. in Computer Science at the University of Stuttgart. She is currently a postdoctoral researcher at Forschungszentrum Jülich. She is committed to interdisciplinary research at the cutting-edge convergence of quantum computing and artificial intelligence. Her research encompasses both foundational theoretical investigations and the development of practical applications, aiming to serve society and benefit humanity.

Dr. Pawel Gora, CEO of Quantum AI Foundation [Quantum AI Foundation](https://www.qaif.org/ "https://www.qaif.org/")

Life Inside the World's Biggest Bitcoin Treasury Company
**👉 Please [RSVP on Luma](https://luma.com/pubkey-aqxx)**
Strategy holds more bitcoin than any other public company on earth, and along the way it's become one of the most talked-about, and most polarizing, names in both finance and Bitcoin. Join us at PubKey for a candid conversation with two people living inside that story: **CJ (Chaitanya Jain)**, Strategy's Head of Investor Relations, and **Ella Hough**, who leads Bitcoin advocacy at the company.
Moderated by **John Balkam**, CMO of [Sovreign](https://sovreign.io/?utm_source=luma), the discussion goes behind the headlines into what it's actually like to execute the Bitcoin Treasury playbook in real time. CJ and Ella will talk about working alongside leaders like executive chairman Michael Saylor and CEO Phong Le, navigating Strategy's role as a lightning rod for both believers and critics, and the personal convictions that brought them to the company. Expect a frank look at the strategy, the scrutiny, and the people behind the world's largest corporate Bitcoin bet.

Drunken Philosophy: Are you really who you think you are? What is the "self"?
I have been studying the question of "self" online with Prof. Ellie Anderson and so I thought a prompt on the "self" might be interesting. Full confession: I had Claude create this prompt and I like it, so here goes:
Imagine a thought experiment that merges two classic puzzles:
> You undergo a procedure, performed neuron by neuron, in which every biological component of your brain is replaced with a functionally identical synthetic substitute. At each step, your behavior, memories, and personality remain unchanged. When the last neuron is swapped, is the consciousness experiencing the world still you? And — more pressingly — was there ever a continuous "you" to begin with?
### Questions to Wrestle With
* If consciousness is purely physical, does the *gradual* nature of the replacement matter, or is it equivalent to being destroyed and rebuilt?
* Could there be a "self" without continuity of experience — even moment to moment, while you sleep?
On a more practical level, consider the simpler case first: **hemispherectomy** patients — people who have had an entire cerebral hemisphere surgically removed — often retain a strong sense of personal identity and continuity. This suggests "you" are not rigidly tied to specific physical material. But does that vindicate the synthetic neuron case, or merely show that identity is more *flexible* than we thought — not that it can survive *complete* substrate replacement?
I used Claude so I could get this out today and let everyone have some time to consider it. Hope to see you at the Oracle. Sorry about the location change two weeks ago. That's what I get for trusting local weather predictions!
