Glass Sphere
A flawless glass orb rests at the precise horizontal fulcrum of a mirrored plane, its polished surface capturing and distorting the surrounding architecture of undulating neon-green light. The stark, symmetrical composition is anchored by the pillar-like reflection below, transforming the fluid wave patterns into a rigorous geometric study. This interplay of optical refraction and stark black void imbues the scene with a cool, hypnotic precision, evoking a sense of suspended digital time. -

Through the Looking Glass
A crystal-clear glass orb acts as a lens, inverting and magnifying the typography and saturated hues of a magazine beneath it. The sharp focus within the sphere contrasts dynamically with the blurred, receding background, creating a playful interplay between clarity and obscurity. This optical distortion transforms mundane printed text into a curated, jewel-like object, evoking a sense of curiosity and whimsical discovery.https://gregurbano.com/2026/07/27/through-the-looking-glass/

Optical, Radar, And Hybrid Indices To Detect Farming Practices In Europe

“HIGHLIGHTS:
• [they] compare[d] Sentinel-1 and Sentinel-2 time series to detect farming practices.
• HyBRIS index is introduced, temporally weighting BSI and VH/VV into a daily index.
• Time-series minima and maxima are used to predict sowing, harvest, and tillage.
• Validation is performed across several years, crop types, and European locations.
• Phenology detection is improved compared to HRL-Cropland.
ABSTRACT: Arable farming practices dictate both crop cycles and soil dynamics, and are central to agriculture's environmental impact and its mitigation. Sowing and harvesting mark the beginning and end of the growing season, while tillage modifies soil structure during the dormant period. Although well-established methods exist for delineating the growing season using phenology and optical data, the detection of farming practices, particularly tillage, remains underexplored. This study investigates the strengths of radar and optical data to retrieve sowing, harvest, and tillage dates at the field level, and proposes a novel Hybrid Bare Soil Radar Index (HyBRIS). Based on Sentinel-1 and Sentinel-2, HyBRIS merges optical and radar data into a single index using a temporally weighted mean. Local minima and maxima of the time series are used to detect farming practices across European sites. Validation is carried out against a reference dataset comprising 238 fields in 11 EU countries, including 462 sowing, 374 harvest, and 388 tillage events covering more than 40 crop types over 8 years. Compared to the Copernicus High Resolution Layer Croplands product (HRL-Cropland), the proposed method based on HyBRIS time series improved sowing and harvest dates detection (MAE 26 and 23 days, respectively). Additionally, this method enabled tillage dates estimation during dormant periods (MAE = 28 days), but tended to overestimate the number of tillage events (producer's accuracy = 97%, user's accuracy = 70%). Incorporating soil moisture data is advised for reducing false positives. The results highlight the potential of optical, radar, and hybrid indices for monitoring agricultural management and supporting environmental stewardship…”

I did a speech yesterday
I'm in a public speaking class and yesterday I had to do a "demonstrative" speech. I chose to demonstrate, using some physical analogs since I can't help my class see into the quantum space, how we've generated electricity for the last hundred-twenty-ish years (ignoring photovoltaics, I wanted to touch on them but I only had 8 minutes). I used a bicycle as my analog, likening the chain-links to electrons on a wire and the gear teeth to the magnetic flux which causes them to move. It was […] -
