A33.00001: Creating a Community for Outreach: FunSize Physics Shireen Adenwalla, Xiaoshan Xu, Leigh M Smith, Jocelyn Bosley Funsizephysics [1] is a website built to communicate the excitement of physics to a broad audience and to provide a central repository for tried and true outreach activities. The contributors are scientists who write engaging articles for the public about their own ground-breaking research, making it unique among science websites. We discuss the lessons learnt, the future plans, the successes and the failures in the first few years of operation. Because the rate of new contributions has always been a stumbling block, in the last two years we have made a concerted effort to encourage scientists to use science writers' descriptions of their own research as an initial rough draft. This helps in overcoming the initial hesitation and has been somewhat successful. We are making an effort to expand the Funsizephysics community by creating a Board of Ambassadors to spread the word, give us feedback and author contributions. Among our successes, is the inclusion of Funsize in a list of the 13 Best Science Blogs [2], commenting that it is among "the most modern physics blogs". |

A33.00002: From Gravitational Waves to James Webb Telescope: How to reach the general public about Physics and Astronomy Ran Li In 2015, when the gravitational waves were first detected, it raised a lot of public interests. In July 2022, when James Webb Telescope sent back its first pictures, the interests in Physics and Astronomy once again were raised in general public. NASA funded a few public libraries around the nation to host a series of events called "NASA @My Library". |

A33.00003: Creating Collaborative Space for Filipino Physics Students and International Scientists' Encounters— The Case of Physics Meetup in the Philippines Christine Adelle R Yuson, Reinabelle C Reyes, Kate Shaw, Bobby Acharya, Bienvenido, Jr. M Butanas, Cecilia O Bucayong, Jake H Destacamento, Vanie Y Benben, Sherwin M Cupida As primarily taught in schools, science tends to focus mainly on technical concepts and equations while overlooking the scientist as a person with sociocultural histories and relationships that impacted scientific discovery. Consequently, most students, especially from the rural areas in the Philippines, are unaware of how to access and be part of these academic family trees and relationships. The pandemic came with an incredible resource— the shift to online tools leveraged communication and collaboration and opened the opportunity to overcome existing physical and geographical barriers. From a small initiative for our physics students in Bukidnon, Physics Meetup has grown to bring together the public from all over the Philippines to learn from and interact directly with prominent physicists, including the Nobel Laureate in Physics Donna Strickland and Breakthrough Prize Laureate Dame Jocelyn Bell Burnell. With volunteers from different schools facilitating our free sessions, we reached nearly 5000 audiences on Zoom and more than 50k on Facebook. This is a feat in the Philippines, where physics learning is not generally emphasized, especially in rural schools. With the ICTP Physics Without Frontiers' support, we also provided mobile data assistance to more than 1000 students to access the internet. As our volunteers and participants become more motivated to pursue physics degrees and careers, we aim to showcase how life-changing collaborative, and inclusive community that promotes physics can be. |

A33.00004: Bringing Veritasium to China to Break Down Science Communication Barriers Hanyu Alice Zhang, Derek Muller Physics educational content has existed on YouTube for over a decade, and YouTube channels in physics and STEM have been inspirational to many aspiring scientists worldwide. Veritasium, a popular science educational YouTube channel with a focus in physics, is no exception. As one of the most established physics YouTube channels, Veritasium has existed since the earliest days of education on YouTube and now has over 13M subscribers and over 1.9B views. |

A33.00005: The Metropolis Algorithm and the women who programmed it (and how it's related to the hydrogen bomb) Adam A Iaizzi In recent years, there has been a huge interest in rediscovering the lost contributions of women and other minorities to science. Here we shine light on yet another such hidden figure: Dr. Arianna Wright Rosenbluth, co-inventor of the Metropolis Monte Carlo method, which is, by any measure, one of the most important algorithms ever developed. Monte Carlo describes a wide range of numerical techniques that use random numbers. The Metropolis algorithm generalized this initially specialized method to solve any equilibrium statistical physics problem (and indeed, many problems outside of physics). Since its introduction in 1953, it has become the most common form of Monte Carlo and spread beyond physics to chemistry, biology, social science, finance, and even pure math; its use is now so widespread that it is commonly mistaken for being a synonym for Monte Carlo itself. Arianna Rosenbluth, herself a child prodigy and fully-qualified physicist, wrote the first complete computer implementation of the Metropolis algorithm. In this talk, I will describe the historical and scientific context for this revolutionary algorithm and its connections to the development of the hydrogen bomb. |

A33.00006: History and Philosophy of PhysicsThat got me thinking, if I could combine the ideas of sequences and series, with permutations and combinations, to design more complex sequences, which might potentially open up new approaches and studies in the field. Swarnav Majumder This brief history and philosophy of physics has been written to give physics students someappreciation of where their discipline has come from, and of the philosophical principlesunderpinning it. It is hoped that this will provide students with a sense of physics as a living,evolving discipline, and of their place in its evolution. Physics, indeed all of science, is not astatic agglomeration of proven facts and inviolable theories. While there are many theories whichare so well tried that they are generally accepted as being correct, all scientific theories are stillopen to attack from some new, reproducible experiment which disagrees with them. The history below bears this out. |

A33.00009: An invoice for a hole in the desert, a matchbox full of neutrinos, and other rediscovered artifacts from the hunt for the ghost particle James R Riordon A recently uncovered cache of materials that neutrino pioneers Clyde Cowan and Fred Reines collected includes a variety of artifacts that haven’t been seen in over a half century. Notes, images, and invoices offer an intimate glimpse into the efforts that led to first direct detection of neutrinos. The items illuminate key moments in the early history of the hunt for the ghostly particle that Wolfgang Pauli initially proposed as an effectively undetectable entity to explain the seemingly inscrutable spectrum of energy in beta decay experiments. I will present a selection of the rediscovered materials that we relied on in writing a new book about the elusive neutrino.* |

A33.00012: A ductility-strength metric for chemically complex alloys Prashant Singh, Duane D. Johnson, Raymundo Arroyave Local lattice distortions (LLD) – relative to average (x-ray) lattice positions – are expected in multiprincipal element alloys (MPEAs) due to the varying complex chemical environments. We suggest a dimensionless metric to characterize ductility in MPEAs using LLD. With its innate quantum-mechanical origins, ductility is clearly affected by LLD arising from increased atomic charge transfer due to electronegativity differences in each local environment (often designated by valence electron count (VEC)). To test this metric, we chose body-centered cubic (bcc) refractory alloys that exhibit a range of ductilitybrittleness. The metric was established by combining the weighted-average VEC and intrinsic parameters related to distortion from the average lattice. The electronic-structure results were calculated using density-functional theory (DFT) methods. The quantitative rank ordering of ductile-tobrittle MPEAs shows good agreement with recent mean-field estimates and experiments. Our results permit a quick ductility assessment to guide the design of more ductile high-temperature MPEAs, and potentially accelerated further if combined with machine-learning. |

A33.00013: How today's policy will shape computing for the next 100 years Suhas Kumar, Alexander Conklin The explosion in artificial intelligence (AI) over the last decade has led to headline-worthy feats across various fields, such as computers beating humans in the game of Go, enabling autonomous vehicles, solving protein folding, and promising brain-like intelligence. Underlying these advances are two key factors: scaling graphics processing units (GPUs) and increased budgets. The two main drivers of computing sucess - increased comuting budgets and manufacturing investments - are running against prohibitive barriers. On the one hand, the end of Moore's law, which essentially stonewalls manufacturing at advanced process nodes, necessitates different forms of post-digital computing. This situation has led to a flurry of exploratory ideas (e.g., quantum computing, neuromorphic computing, analog computing, etc.), which are, at best, modestly mature, and urgently need prioritization at the policy level. On the other hand, there is an exponential and insatiable demand for compute, fueled by the AI revolution. How do we both meet the societal demands and also pave the path for the next type of computer? The answer lies in both understanding the options in front of us and also in udnerstanding the budget demands, which presents a landscape that is very different from the era of digital computing. |

A33.00014: The Physics Behind Cooking Intelligence Lisa R Wang, Yifei Jin, Yifei Jin Cooking reflects human’s highest intelligence from both scientific and artistic perspectives. This work investigates the essential physics behind intelligence in cooking. The physics behind cooking time and preparation method is carefully studied and quantitatively presented, which reveals the most interesting science behind various recipes, tricks, and mysteries to achieve optimal temperature and flavor in cooking and culinary arts. Firstly, the cooking time’s square power relation with the food’s physical dimension explains the most delicate thoughts behind fast cooking and why Chinese and Indian foods prefer shredding the food into tiny pieces before cooking. Secondly, the orders of difference in magnitude between thermal and mass diffusivity coefficients explain many food preparation methods used widely throughout centuries of human history in both Eastern and Western culinary cultures. |

A33.00015: Quantum oscillations and current distribution in Cylindrical graphite Narayan Kunchur, Stanislaw Galeski, Fabian Menges, Tobias Meng, Rafal Wawrzynczak, Bernd Büchner, Claudia Felser, Johannes Gooth We experimentally investigate the Quantum oscillations on macroscopic cylindrical graphite to study the influence of geometry and magnetic field on the behavior of charge carriers. The magnetic field is applied perpendicular to the axis of the cylinder and the current is injected along the axis. The Landau quantization depends on the radial component of the magnetic field, which results in an angular dependence of the energy landscape on the surface of the cylinder. This in turn leads to a redistribution of charge carriers on the surface of the cylinder. The cylindrical graphite is modelled as a resistor network of strips of flat graphite. We show that the resistor network model qualitatively captures the quantum oscillatory features observed on cylindrical graphite and can predict the angular distribution of current on the surface. The experiments on the cylindrical graphite thus illustrates the interplay of geometry and magnetic field to control the spatial density of charge carriers in a solid state system. |
