Hemimorphite

Hemimorphite, is a sorosilicate mineral which has been historically mined from the upper parts of zinc and lead ores, chiefly associated with smithsonite. It was often assumed to be the same mineral and both were classed under the same name of calamine. In the second half of the 18th century it was discovered that there were two different minerals under the heading of calamine - a zinc carbonate and a zinc silicate, which often closely resembled each other.

The silicate was the more rare of the two, and was named hemimorphite because of the hemimorph development of its crystals. This unusual form, which is typical of only a few minerals, means that the crystals are terminated by dissimilar faces. Hemimorphite most commonly forms crystalline crusts and layers, also massive, granular, rounded and reniform aggregates, concentrically striated, or finely needle-shaped, fibrous or stalactitic, and rarely fan-shaped clusters of crystals.

Some specimens show strong green fluorescence in shortwave ultraviolet light (253.7 nm) and weak light pink fluorescence in longwave UV.

Finding Another Earth

A newly discovered exoplanet, Kepler-452b, comes the closest of any found so far to matching our Earth-sun system.

I share an excerpt from a JPL article:

About a dozen habitable zone planets in the Earth-size ballpark have been discovered so far -- that is, 10 to 15 planets between one-half and twice the diameter of Earth, depending on how the habitable zone is defined and allowing for uncertainties about some of the planetary sizes.

The new discovery, Kepler-452b, fires the planet hunter's imagination because it is the most similar to the Earth-sun system found yet: a planet at the right temperature within the habitable zone, and only about one-and-a-half times the diameter of Earth, circling a star very much like our own sun. The planet also has a good chance of being rocky, like Earth, its discoverers say.

Kepler-452b is more similar to Earth than any system previously discovered. And the timing is especially fitting: 2015 marks the 20th anniversary of the first exoplanet confirmed to be in orbit around a typical star.

New Horned Dinosaur Species Called 'Most Striking' Ever Discovered

Scientists recently discovered the fossilized bones of a striking new species of horned dinosaur in southern Alberta, Canada. The 200-plus fossils are believed to have belonged to four specimens of Wendiceratops pinhornenis (https://www.rom.on.ca/en/exhibitions-galleries/exhibitions/dino-hunt)-- three adults and one young dino.

According to the researchers, W. pinhornenis lived about 79 million years ago. Measuring about 6 meters (20 feet) in length and weighing more than a ton, it sported a parrot-like beak suited to eating scrubby plants. And while the dinosaur likely had a wide frill extending from its neck and horns over the eyes, its most bizarre feature was the giant horn on its nose. It's the earliest known example of a tall, upright nose horn in the horned dinosaur family.

Full Moon Photographed From Apollo 11 Spacecraft

This outstanding view of the full moon was photographed from the Apollo 11 spacecraft during its trans-Earth journey homeward.

When this picture was taken, the spacecraft was already 10,000 nautical miles away. On board Apollo 11 were commander Neil Armstrong, command module pilot Michael Collins and lunar module pilot Buzz Aldrin.

While astronauts Armstrong and Aldrin descended in the lunar module Eagle to explore the moon, Collins remained on the command and service module Columbia in lunar orbit.

The video link was relatively primitive: they had a weird semi-mechanical color video system inside the spacecraft, but only blurry B/W video on the lunar surface (later lunar missions had better).

But for stills they were using Hasselblad cameras with nice color film, and the pictures were quite high-resolution.

Lorenzo Alessandri (Turin, February 16, 1927 - Giaveno, May 15, 2000) was an Italian painter, exponent of surrealism

His early childhood years are narrated in the collection of memories Zerubbabel (Skira, 2012), text rich in testimonies collected by his official biographer Concetta Leto.

Self-taught, at age 13 Alessandri began to incise the linoleum, while two years later he painted his first oil painting. At the end of the Second World War, he opened his first studio, called "La soffitta macabra" (the macabre attic).
Immediately after the war, Alessandri perfected the study from life (still-life drawing) thanks to the master of charcoal drawing Giovanni Guarlotti, who  however refused to teach him the use of color.
It was during this period that Alessandri created fantastic characters, made as Indian ink drawings and known as the pascals.

Katherine Johnson: She Was a Computer When Computers Wore Skirts

Katherine Johnson (born August 26, 1918) is an African-American physicist, space scientist, and mathematician who contributed to America's aeronautics and space programs with the early application of digital electronic computers at NASA. Known for accuracy in computerized celestial navigation, she calculated the trajectory for Project Mercury and the 1969 Apollo 11 flight to the Moon.

Her work at NASA's Langley Research Center spanned 1953 to 1986 and included calculating the trajectory of the early space launches.

The following NASA article dates back to 08.26.08, but it deserves to be read.
I share an excerpt.

"I didn't have time for that," said Johnson in her Hampton home. "My dad taught us 'you are as good as anybody in this town, but you're no better.' I don't have a feeling of inferiority. Never had. I'm as good as anybody, but no better."

But probably a lot smarter. She was a "computer" at Langley Research Center "when the computer wore a skirt," said Johnson. More important, she was living out her life's goal, though, when it became her goal, she wasn't sure what it involved.

Johnson was born in White Sulfur Springs, W.Va., where school for African-Americans stopped at eighth grade. Her father, Joshua, was a farmer who drove his family 120 miles to Institute, W. Va., where education continued through high school and then at West Virginia State College. He would get wife Joylette a job as a domestic and leave the family there to be educated while he went back to White Sulfur Springs to make a living.

Katherine skipped though grades to graduate from high school at 14, from college at 18, and her skills at mathematics drew the attention of a young professor, W.W. Schiefflin Claytor.

"He said, 'You'd make a good research mathematician and I'm going to see that you're prepared,' " she recalled.

"I said, 'Where will I get a job?'

"And he said, 'That will be your problem.'

"And I said, 'What do they do?'

"And he said, 'You'll find out.'

"In the back of my mind, I wanted to be a research mathematician."

I knew a computer growing up, because she worked on Loran with my dad. Before programming was abstracted into languages that was how you made complex calculations.

I'm not sure I would consider Ms Johnson a genius based on trajectory calculations, but I am very glad we had someone so capable doing them. I don't doubt their complexity (a choice of approximations was required) and importance, but I suspect she did more interesting (for her) work in the rest of her career. Repeatedly cranking a glorified calculator was almost certainly as tedious as it was necessary.

Visualising the number π

The first frame shows 3 green segments filled in, these have area 3 square units and represent the first digit of π. Next is 1 brown segment which is ten times smaller than one of the 3 outside greens- i.e. it has area 0.1. The 4 inside that then have area 0.04 (3.14 so far) and as we zoom in more and more digits of π are revealed.

Introduction
I teach mathematics and science and I write for "Scuola e Didattica"- Educational fortnightly magazine in Italian (Editrice La Scuola).

I'm also interested in web 2.0, social network and much more. I love reading, writing, painting, photography, good music, and more.

My posts are prevalently about Science and Mathematics for a general audience, but also about Art, beautiful images/photo and interesting  gifs. I share often scientific news that can be useful to many people.

I would like to look at the profiles of everyone who circles me, but there are too many. ;)
Anyway, I will definitely look at your profile if you engage with my posts.

Furthermore, I am interested in following people who post quality original content, regardless of the number of their followers. 

Instead I am not interested in following people if they never engage with my own content.

If you consider interesting my posts, you can circle me:). I'd like to read your posts and to interact with you here on Googleplus
Bragging rights
I experimented at school a research scholarship in Science, producing approximately over 200 pages of Materials for Science, published by IRRE- ER (Institute of Educational Research Emilia-Romagna, Italy). I was also part, along with 50 teachers selected nationwide, of The SENIS Project, a pilot project from Ministry of National Education for improving the scientific formation of teachers at secondary school. This Project has collected a lot of educational resources, published in a book by Ministry of National Education.
