The image shows two children standing in a doorway, separated by vertical panels that resemble window frames. The child on the left is wearing a polka dot dress and holding something close to their face with both hands near the mouth area. Their hair appears unkempt and they have an expression of distress or contemplation. On the right stands another child dressed in overalls, which appear worn out and stained. This child's arms are also positioned around the neck level as if mimicking a gesture made by the other person on their side. Both children seem to be in disarray; one is holding what looks like bread above their mouth while the other has an unfastened button or item near its chest.

The background reveals wooden planks and weathered paint, suggesting this could be a rustic setting possibly indicative of hardship times based on clothing condition and overall atmosphere. There's some debris visible in the upper left corner against one of the panels behind them, further reinforcing that they may not have access to clean living conditions or resources for proper hygiene.

The image is presented as part of Dorothea Lange's work documenting various aspects of American life during challenging times. The specific caption indicates it was taken at Dead Ox Flat in Malheur County, Oregon and features the Browning children; further information about this series can be found o [...]

A black and white photo shows a woman in the process of organizing or retrieving jars from shelves. She is wearing a knee-length dress with floral patterns, shoes that appear to be Mary Janes, which are low-heeled pumps commonly worn by women for comfort during the early-to-mid-20th century. The setting seems like an old-fashioned pantry or cellar as evidenced by wooden racks and crates on the floor holding more jars of preserved fruits and vegetables. Various tags with handwritten labels adorn some items, indicating organized storage but possibly outdated methods such as "red grapes," which may not be a typical item to preserve in this manner today. The scene depicts everyday life during an earlier era when home food preservation was prevalent due to economic reasons or lack of access to modern conveniences like supermarkets.

A black and white photograph depicts a man standing on logs in shallow water, holding what appears to be a long tool or weapon. He is wearing casual attire including trousers, shoes, socks, gloves, a shirt with rolled-up sleeves, and a cap. In the background are trees and more floating tree trunks suggesting this could be near a river or lake. The image includes text at the top right corner indicating "1930" in Japanese characters, which might relate to its date of creation. There is also additional descriptive text provided: "Pond monkey" channels log raft. Keno, Klamath County, Oregon." and General caption number 61 https://images.loener.nl/DorotheaLange/full/6495/6495b829ba25398d90c4ffc7.jpg The overall scene is indicative of a historical or rural setting where manual labor involving water bodies, such as rafting, may have been common.

Black and white photograph of Emmy Noether. She is standing just behind an ornate chair, wearing a white striped blouse with puffy shoulders, a fluffy bow at her neck, and a heavy long skirt cinched with a belt. Her dark hair is pulled back and she is looking a bit to the photographer's right.

Felix Klein lectured “On Hilbert’s first note on the foundations of physics" at the Mathematical Society of Göttingen #OTD in 1918. He included excerpts from letters in which he and Hilbert give priority to Emmy Noether’s results on conservation of energy in general relativity. (1/n) 🧪 ⚛️ 👩‍🔬
