This early-1940s Pennsylvania-Central Airlines postcard captures the polished, idealized image of the American “air hostess” at the dawn of commercial aviation’s first glamour age. The photograph, rendered in soft black-and-white against a bold blue background, presents a young woman in the airline’s uniform cap, complete with the PCA winged insignia—a small but proud emblem of a rapidly expanding industry. Her expression is warm and inviting, the kind of carefully cultivated friendliness airlines of the period highlighted to reassure first-time passengers and promote air travel as both modern and refined.

The caption beneath—declaring her among the “loveliest” hostesses in America—reflects the era’s highly gendered marketing strategies, when airlines routinely emphasized beauty, charm, and poise as central components of professional identity. More than just a portrait, the postcard stands as a piece of aviation advertising history: a reminder of how early airlines blended hospitality, glamour, and aspirational imagery to make flying feel both safe and sophisticated at a time when commercial aviation was still new to much of the public.

Richard Salter Storrs, Congregationalist, says the gospel endeared respect for lives and property of others, lessened internecine wars, increased compassion for sick & ship-wrecked Mariners. It “constrained” people to divide their last morsel with famished travelers.

Would those who claim to be “men of God” today, instead, warn you about sick travelers out to constrain UR family to a single morsel?

How can you live out these ideals?

RICHARD SALTER STORRS (1787-1873) Always Abounding in the Work of the Lord "So, wherever these men of God have gone, they have inspired respect for the lives and property of strangers; — disarmed the barbarian of his spear and poisoned arrows — warmed his bosom with compassion for the sick and ship-wrecked mariner — and constrained him to divide his last morsel with the famished traveler, and speed him on his way."

Result of a Principal Component Analysis (PCA) created from combined median composites of Sentinel-1 and Sentinel-2 imagery — somewhere in the Sudanese desert.

This PCA composite brings out contrasts between lithologies, structural domains, drainage patterns, and surface materials, highlighting features that are nearly invisible in standard RGB representations.

And yes — it also happens to look stunning.

False-color PCA composite from Sentinel-1 and Sentinel-2 data showing vivid contrasts in lithology and surface materials in a desert region of Sudan. Bright reds, greens, blues, and purples highlight drainage networks, bedrock structures, and geomorphological boundaries.

Exploring large-scale landscape structures with a simple Principal Component Analysis (PCA) applied to a MODIS composite.

The PCA reveals striking contrasts in surface materials, vegetation patterns, and terrain transitions across western Canada — from the Rocky Mountains into the prairies and the Canadian Shield.
Even with moderate-resolution MODIS data, spectral variability produces a surprisingly rich view of regional geography and geomorphology.

A large composite map showing western Canada, with the Rocky Mountains on the left and the prairies and the Canadian Shield extending to the right.
In the center, a bright false-color PCA image derived from MODIS satellite data is overlaid: vivid reds, purples, greens, cyans, and yellows highlight differences in surface materials, vegetation, and terrain units.

The PCA highlights contrasts between different lithologies, structural domains, and surface materials, revealing subtle geological features that are hard to distinguish in standard RGB composites.

And yes — it also looks simply beautiful.

Santé numérique : quand la cybersécurité tombe en hypotension

Le secteur de la santé est en alerte rouge : les cyberattaques se multiplient, paralysent des hôpitaux, volent des données sensibles. La France et l’Espagne en premier plan, l’Amérique latine en miroir d’un chaos numérique global.
Le programme CaRE est financement assuré uniquement jusqu’à fin 2024 selon la Cour des comptes. La poursuite incombe aux finances des hôpitaux, dès 2027. Mais à quel prix ?
Ils disent « les seuls beaux yeux sont ceux qui vous regardent avec tendresse », disait Coco Chanel... mais dans les hôpitaux, ce sont les écrans clignotants qui vous regardent. Ce n’est plus une option : la cybersécurité en santé est devenue vitale.

L'image montre un appareil de mesure de la pression artérielle, de couleur blanche, placé sur une feuille de papier avec un électrocardiogramme (ECG) imprimé dessus. L'appareil est digital et affiche des informations telles que la pression systolique, diastolique et le pouls.
Les informations chiffrées montrent une tension à 9/6, près d'une hypotension, la pulsation cardiaque est à 94.
À côté de cet appareil se trouvent plusieurs flacons blancs de médicaments ouverts, avec des comprimés éparpillés sur la table. Certains comprimés sont blancs, d'autres sont de couleur beige, jaune et vert. On peut également apercevoir un brassard noir utilisé pour la mesure de la pression artérielle.

Behind the scenes of “beautiful scientific graphics”

If you think that clean, elegant visuals in scientific reports are produced in a couple of clicks — I’m here to disappoint you. 🙂

Here’s one of many failed attempts to visualize results based on thermodynamic modeling of geochemical processes.

Turning raw multidimensional data into something that a human reader can intuitively grasp is a separate challenge — with dozens of input parameters and only a few truly useful outcomes.

Good science is not only about computation, but also about communication.

An early (and chaotic) attempt to visualize clustering results in 3D PCA space. A reminder that good figures rarely happen on the first try.

🛰️ Today I’m sharing one of my favourite large-scale remote sensing experiments:
a Principal Component Analysis (PCA) of MODIS composite data for the three central provinces of Canada (Alberta, Saskatchewan, Manitoba).

On this map:
- PC1 emphasizes broad ecological zones and vegetation productivity
- PC2 highlights soil and surface moisture differences
- PC3 captures subtle spectral variations — often linked to geology, wetlands, disturbance patterns, or local microclimates

Even though it looks abstract, PCA is a kind of “spectral fingerprint” of the land. It summarises thousands of square kilometres into a single visual structure that shows how the Canadian Prairies and Boreal regions differ and transition into one another.
