Inspired by beetles and fabricated by a robot, this striking garden pavilion kicks off the Engineering Season.
V&A.
Rectifier and dual triode vacuum tubes on the job since 1963. The glowing filaments heat a cathode sleeve that boils off electrons that are then captured by a charged plate. For the rectifier, they can only go in one direction, and AC is converted to DC. For the dual triode, control grids fashioned like a finely wound fence are interposed whereby a small change on the grids cause a large change on the plates, and amplification is achieved.
Zoom to explore.

Hey there, little light bulb.
Look beneath your sunny glow.
There lie a dozen empty flower pots
filled with seeds waiting to grow
A macro look at the stem part of the stamen called the filaments. At the top of these stems are the anthers which produce the pollen.
I like the green color of these filaments, as well as the fuchsia of the petals...

A laterally oriented structure in the Sun's corona seemed to balance itself (watch the area to the upper left) above the Sun's surface for at least two days (May 26-28, 2015). The structure seemed to fade about halfway through the video, but then reappeared even clearer than before. The activity was imaged in a wavelength of extreme ultraviolet light.

Nature's filaments 'lighting up' the 'scent' from one extremely fragrant rose in the garden.
The stamen (from Latin stamen meaning "thread of the warp") is the male organ of a flower. Each stamen generally has a stalk called the filament (from Latin filum, meaning "thread"), and, on top of the filament, an anther (from Ancient Greek anthera, feminine of antheros, flowery) and pollen sacs.
