Ilford Pan 100 (FF) English Alt Text: A close-up black-and-white image of a metal ashtray. Inside, there’s a partially smoked cigarette, a dry leaf, and scattered ashes. The ashtray has a circular opening in the center and shows signs of frequent use with stains and debris. The composition evokes themes of habit, decay, and stillness, offering a quiet, contemplative moment frozen in time. 中文替代文本： 这是一张黑白特写照片，展示一个金属烟灰缸。烟灰缸内有一根抽了一半的香烟、一片干叶和散落的烟灰。中央有一个圆形开口，表面污渍斑斑，显示出频繁使用的痕迹。画面传达出习惯、衰败与静止的主题，呈现一个凝…
Ilford Pan 100 (FF) English Alt Text: A black-and-white photo taken from inside a public bus. The foreground shows the back of a person’s head seated near a window, with another passenger seated further ahead. The bus seats have modern headrests and handles. Sunlight filters through the window, casting reflections of the interior and revealing an exterior view of a staircase and railing, suggesting the bus is near a pedestrian overpass or station. The mood is quiet and observational, capturing…
Ilford Pan 100 (FF) English Alt Text: A black-and-white urban photograph featuring a large metal sculpture spelling “METRO” in capital letters. The sculpture stands in front of a modern glass building, which also displays the word “METRO” above its entrance. Two people are partially visible behind the letters—one seated, one leaning forward. Reflections of pedestrians appear on the glossy surface below. Trees and bushes add greenery to the scene. The composition blends architecture, typography…
Ilford Pan 100 (FF) English Alt Text: A black-and-white photo of a public art installation in an urban plaza. The central sculpture is a large hyperboloid structure made of metal rods, surrounded by flowing metal tubes. In the foreground stands a flame-like sculpture made of perforated metal sheets. The ground features circular patterns. Background signage in Chinese and English suggests the location is in a Chinese-speaking region. The scene merges geometry, engineering, and artistic expressi…

Abstract: Atoms and simple molecules are excellent candidates for new standards and sensors because they are both all identical and their properties are determined by the immutable laws of quantum physics. Here, we introduce the concept of building a standard and sensor of radiative temperature using atoms and molecules. Such standards are based on precise measurement of the rate at which blackbody radiation (BBR) either excites or stimulates emission for a given atomic transition. We summarize the recent results of two experiments while detailing the rate equation models required for their interpretation. The cold atom thermometer (CAT) uses a gas of laser cooled $^{85}$Rb Rydberg atoms to probe the BBR spectrum near 130~GHz. This primary, {\it i.e.}, not traceable to a measurement of like kind, temperature measurement currently has a total uncertainty of approximately 1~\%, with clear paths toward improvement. The compact blackbody radiation atomic sensor (CoBRAS) uses a vapour of $^{85}$Rb and monitors fluorescence from states that are either populated by BBR or populated by spontaneous emission to measure the blackbody spectrum near 24.5~THz. The CoBRAS has an excellent relative precision of $u(T)\approx 0.13$~K, with a clear path toward implementing a primary

Lucky SHD 400 (6x6) English Alt Text: A dramatic black-and-white photo of tall modern apartment buildings forming a semi-enclosed courtyard. The buildings feature repetitive patterns of windows and balconies, with vertical and horizontal lines creating a geometric rhythm. The central building has a darker facade with a vertical strip of windows, possibly indicating a stairwell. The photo is taken from a low angle, emphasizing the towering height and density of the structures. The monochrome pa…

In the center, a small circular traffic island with a flower bed adds a touch of nature. To the right, a cyclist rides past a modern building with large support columns and an overhanging structure. Trees and distant buildings line the background. The composition blends urban architecture with subtle natural elements, evoking a quiet, reflect…
Lucky SHD 400 (6x6) English Alt Text: A narrow alleyway bordered by a concrete wall on one side and dense foliage on the other. In the center, several white bicycles are piled haphazardly, some overturned or leaning against each other. These bikes appear to be part of a shared bike system, identifiable by uniform frames and QR code labels. The scene is cluttered and chaotic, suggesting abandonment or improper parking. The black-and-white tone adds a somber, gritty atmosphere, emphasizing urban…
Lucky SHD 400 (6x6) English Alt Text: A quiet urban street scene in black and white. A row of large, empty concrete planters lines the sidewalk, creating a strong sense of depth and perspective. On the left, a building with multiple windows stretches into the distance, and a lone person walks away from the camera. On the right, evenly spaced trees add contrast to the geometric shapes of the planters. The street is calm, with no visible traffic, and the composition emphasizes symmetry and solit…

Just back from 4 days in the Great Otway National Park, Victoria. Stunning place, and we mostly managed to stay dry in the wettest part of the state. Here’s photos from a walk along the coastal path. #bushwalking #straya

Two hikers walk along a coastal path surrounded by green bushes, with hills and a bit of ocean visible behind them under partly cloudy skies.
