Isamu Noguchi: a sculpture you can switch on

Quick read · 1 min read

In 1951, after encountering traditional lanterns in Gifu, Isamu Noguchi began imagining Akari: luminous sculptures made from washi paper and slender bamboo ribs. Light passes through the material and becomes part of the work, rather than simply illuminating it. [1]

The Metropolitan Museum holds Akari E, a hanging lamp built from geometric forms. Its story includes an effort to revive local craftsmanship: an object can be a sculpture and still light up a room. [2]

Take this with youOur little exercise: look at a lamp switched off, then on. The design changes with the light. No gallery opening required.

Socrates and the limits of expertise

Quick read · 1 min read

Socrates left no writings: we know him through ancient accounts that do not always agree. The Stanford Encyclopedia of Philosophy cautions us about this. His questioning nevertheless offers a useful idea: recognising the limits of what we know. [1]

In Plato’s Apology, Socrates encounters craftspeople with skills he does not possess. Trouble begins when that ability convinces them they are wise about other matters too. Being good at something does not automatically grant a universal licence to know. [2]

Take this with youOur exercise: choose one of your beliefs and ask what evidence could change it. Your inner know-it-all deserves at least an afternoon off.

Venus flytrap: a leaf waiting for confirmation

Quick read · 1 min read

Dionaea muscipula forms a small rosette of leaves. Their tips carry traps with two lobes, often reddish inside, and marginal bristles that interlock when the trap closes. Those are not teeth: we are still very much in the plant kingdom. [1]

Kew explains that, typically, two closely spaced touches to sensitive hairs trigger closure: two hairs can be touched, or the same one twice. Captured prey supply nutrients that are scarce in the ground; carnivory is a response to nutrient-poor soil. [2]

Take this with youThe little discovery is a leaf transformed into a trap. Our own joke: even this botanical doorkeeper waits for confirmation before closing.

The sea otter already brought the tools

Quick read · 1 min read

Sea otters can use stones and shells to break open their prey. They do not all do it in the same way: U.S. Geological Survey data show large differences between individuals, linked partly to diet and food availability. [1]

Here is a concrete example: after surfacing, an otter can roll onto its back, rest a stone on its chest and pound a hard-shelled mollusc against it. Tools for Critical Thinking in Biology describes the behaviour: tool and workbench travel together. [2]

Take this with youOur comment: when lunch puts up a fight, a tool helps. Around here, at least, the toolbox floats.
