Fernlike Snow Crystal

December 25, 2022

Wilson_snow_crystal_1e018f4a57d4c9c72ca62b8e6a3b374a

Photographer: Wilson Bentley

Summary Author: Jim Foster

The lacy crystal shown above, as well as hundreds of other snow
crystals, were first photographed by Wilson Alwyn Bentley (1865-1931).
These photomicrographs are housed at the Bentley Snow Crystal
Collection in the Schwerdtfeger Library, at the University of
Wisconsin. According to the Lee/Magano system, this lovely specimen
is classified as a fernlike dendrite snow crystal ( P2e). Snow
crystals are six-sided because the water molecules that form them are
characteristically arranged in layers of hexagonal rings. This
results in their stunning six-fold symmetry.

Glacial Striations in Victoria, British Columbia

November 25, 2022

Photographer: Joe LaCour

Summary Author: Joe LaCour

Just a few hundred meters southeast and across the street from where
the Coho ferry docks in downtown Victoria, British Columbia,
you can see a great example of the power of the glaciers from a
previous ice age. Some 15,000 years ago, a glacier flowed over what
is now Victoria. The surface of the outcrop shown above was
grooved, scratched, and polished by the cutting action of pebbles
and boulders dragged along like a piece of giant sandpaper frozen to
the bottom a glacier. This fascinating ice age relic might be easy to
miss as the attention of many passers-by is captured by the striking
Legislative Parliament Building (not in photo). Note that the
bronze plaque in the foreground - Glacial Grooves and Striations
- acknowledges Victoria's glacial history.

Photo details: Leica M9 Digital camera; 35mm Summicron lens; f13; 1/60
second exposure; ISO320; processed with DxO PhotoLab.

Featured above are views of the visible planets in our solar
system, and the crescent moon, as seen from Taipei (top), Yuen
Long, Hong Kong (middle) and the Dolomite Range of Italy (bottom,
note that Neptune and Uranus are also visible here). Such an
unusual alignment can be observed only about once every 20-years.
Top and middle photos were taken on June 23, 2022, and the bottom photo
was taken on June 25, 2022. All photos were captured looking east, just

Lamiaceae Family of Aromatic Flowering Plants

October 25, 2022

Summary Author: Menashe Davidson

The Lamiaceae are a family of flowering plants commonly known as
mint or deadnettle. Plants in this family are characterized
by square stems, paired and simple leaves, and two-lipped
open-mouthed tubular flowers. Many of these plants are aromatic in all
parts and include widely used culinary herbs like basil, mint,
rosemary, sage, lavender, and salvia. They’re cultivated not only for
their aromatic qualities, but also for their ease of cultivation and
for their decorative foliage (coleus, for instance).

The photos above demonstrate the botanical richness of plants in
the Lamiaceae family. They were all grown in containers in my home
garden in Rishon Le Zion Israel, on September 4, 2022.

Picture 2 - Coleus amboinicus -- ornamental

Picture 3 - rosemary (Salvia rosmarinus) -- herb
