If you are interested in maps and city views and especially in the 'boundaries' between city and countryside, please have a look at this video: youtube.com/watch?v=4SBmTdwOnQ
I call this #boundary a 'spatial differentiation'. Please share your thoughts.
The video could also be a useful teaching tool for BA seminars in in #History , esp. #urban and #spatial history.

‘Unshore’, Old suitcase, sand and air humidifier, 2024.

c. 1400, unseur, of a place, “not safe against attack,” also, of persons, “lacking certainty,” from un- “not” and sure. By early 15c. as “dependent on chance.”
The key of return—the symbolic act of holding onto the keys to their homes—embodies Palestinian resilience and the enduring connection to their homeland amid the ongoing genocide in Gaza (and previously, the Nakba). Central to Palestinian culture and activism, it signifies resistance and the relentless pursuit of justice.

Using sand from his garden, Alaric explores the concept of “home from home,” with the coastline serving as both a border and a gateway, symbolising departure, arrival, and displacement. This piece reflects on “emotional baggage” and “living from a suitcase,” addressing the shared trauma of refugees and rough sleepers.

Surface Water Penetrates Deep into Earth, New Research Suggests
A few decades ago, seismologists identified a thin layer with a lower velocity in Earth’s metallic liquid core. The origin of this layer, known as the E’ layer, has been a mystery. Now, geoscientists have revealed that water from the Earth’s surface can penetrate deep into the planet, altering the composition of the outermost region of the core and creating the E’ layer.
