WIST Quotations

A quotation from Oliver Wendell Holmes, Sr.

Grant us Thy truth to make us free,
And kindling hearts that burn for Thee,
Till all Thy living altars claim
One holy light, one heav’nly flame.

Oliver Wendell Holmes, Sr. (1809-1894) American poet, essayist, scholar
Poem (1848), “A Sun-Day Hymn,” st. 5

[9715] - 2019

Part of a series I've made back in 2019, called it "Fire and Water". It was fun (and messy). Despite using the maximum shutter speed here (1/8000 sec), apparently this wasn't enough to freeze the motion of the water droplets - they were ejected from a syringe. It is such situations that call for working with "flash duration" instead of the typical HSS (or high-speed) mode in the speedlites. Unfortunately, back then my knowledge was limited, and till this very day, I don't think I can work with such method.

Specs for those who care about them:
- Canon EOS 7D.
- Canon EOS 100mm f/2.8 Macro.
- F/5.6.
- 1/8000 sec.
- ISO 200.

🟢 Il nous faudrait 25 000 agents pour mener à bien les projets de transition sur les territoires.

Ces besoins d’ingénierie territoriale climat représentent 1,5 Md€ par an.

👉 Comment les financer ?

C’était l’objet du colloque organisé par #FLAME que nous accueillions avec Tristan Lahais

Soft candlelight from real candles illuminated the dim environment in Sts. Cyril and Methodius Church, the first Serbian Orthodox Church in Ljubljana Slovenia. The warm glow created a serene and contemplative atmosphere.

Visualizing Unstable Flames

Inside a combustion chamber, temperature fluctuations can cause sound waves that also disrupt the flow, in turn. This is called a thermoacoustic instability. In this video, researchers explore this process by watching how flames move down a tube. The flame fronts begin in an even curve that flattens out and then develops waves like those on a vibrating pool. Those waves grow bigger and bigger until the flame goes completely turbulent. Visually, it’s mesmerizing. Mathematically, it’s a lovely example of parametric resonance, where the flame’s instability is fed by system’s natural harmonics. (Video and image credit: J. Delfin et al.; research credit: J. Delfin et al. 1, 2)
