Human Skull Dimensions Follow Golden Ratio: Study | Other Sciences - Sci-News.com

The Golden ratio principle is present in the architecture and evolution of the human skull, suggests a new study by researchers from the Johns Hopkins University School of Medicine and Nationwide Children’s Hospital by News Staff at Sci-News.

In human skulls, division of the nasioiniac arc (from nasion to inion, NI) by bregma into a shorter frontal arc (from nasion to bregma, NB) and longer parietooccipital arc (from bregma to inion BI), creates a geometrical relationship in which the ratio of the nasioiniac arc over the bregma-inion arc (NI/BI) coincides with the ratio of the bregma-inion arc over the nasion-bregma arc (BI/NB), both 1.6. The subdivision of the nasioiniac arc by bregma into two unequal arcs emulates the geometrical division of a line into the Golden ratio.

Represented by the Greek upper-case letter phi (Φ), the Golden ratio belongs to the set of irrational numbers and expands in a decimal form as 1.618033…

The first written description and illustration of how to obtain the Golden ratio geometrically came from Euclid of Alexandria around 300 BCE.
Eighteen centuries after Euclid, in 1509, Franciscan friar and mathematician Fra Luca Bartolomeo de Pacioli dedicated an entire book to the Golden ratio and titled it De Divina Proportione (The Divine Proportion)...

In a new study investigating whether mammalian skull shape follows the Golden ratio, Professor Rafael Tamargo and Dr. Jonathan Pindrik compared 100 human skulls to 70 skulls from six other mammals (lion, tiger, rhesus monkey, domestic dog, blue monkey, and Eastern cottontail rabbit)...

The findings were published in the September 2019 issue of the Journal of Craniofacial Surgery.

Calls to give support to local bookshops | Island News - Isle of Wight Observer

In advance of the IW Literary Festival, Isle of Wight MP Bob Seely has called on Islanders to support local bookshops, saying they offer an experience not available on the internet by Jade Honey, Isle of Wight Observer.


Mark Sames, from Ryde Bookshop in Ryde High Street, said: “We were established in 1988, we have over 100,000 books in 10 rooms on three floors. There are both second-hand and new books on virtually every subject, so we are able to offer great choice and excellent value. Why browse virtually on the internet when you can browse for real, and walk away there and then with your book of choice. We are open seven days a week including bank holidays.”

Margaret Norris from Books2Love in Pyle Street Newport said: “’Customers love to browse in this old-fashioned bookshop with knowledgeable staff giving a personal service and a huge selection of books both new and second-hand to choose from. Toasted teacakes and a variety of coffee; what’s not to like?”...

Mr Seely said: “It is these smaller local stores that offer not just a good selection of books, but the staff have a unique experience, knowledge and passion for books and literature. These shops also provide a social hub as well as contributing to the fabric of our town centres. It is too easy to browse the internet and purchase online and forget that there are smaller independent retailers right on our doorstep that offer excellent choice and value.”

There Is No Such Thing as a Person of the Book | Inspiration & Entertainment - Chabad.org

I can’t remember my first day of Hebrew school, and my bar mitzvah portion is a blur. But I’ll never forget the day a rabbi told me to stop reading so many Jewish books, notes Scott Hirsch, Chabad.org. 

Photo: Chabad.org
It was one of the most surprising, absurd, and ultimately, meaningful moments of my Jewish education.

The rabbi was Yosef Moscowitz of Chicago’s Bucktown Chabad, and he’s on my mind because I’m sitting on a park bench in Jerusalem with no idea where I’m going to sleep tonight—it’s Chol Hamoed and every hostel and Airbnb is fully booked. But despite my lack of lodging, I’m feeling strangely upbeat, and I have Rabbi Moscowitz to thank for that.

I was 30 years old when I first reached out to the rabbi. Despite a strong Jewish background, I was interested in tackling Torah on my own terms for once—that is to say, not learning about Judaism, which I felt I knew enough about, but Torah. As a literature student and introvert, I decided maybe I should get to the heart of my tradition—the texts.

The rabbi met me for coffee, and after the usual introductions and games of Jewish geography, I finally got to my main question: what books would he recommend for someone like me—a bookish, shy-ish, Jewish guy looking to go deeper into the texts of our people?...

As an American, I forget there are places where Jews aren’t a minority; where the Jewish holidays dictate the ebb and flow of the everyday calendar. And Chol Hamoed is vacation time in Israel. Schools shut down. Families go on vacation. Parks, hostels, and bus stations swell with students and travelers.

Why historians need to take scientific fieldwork more seriously | Science - Times Higher Education (THE)

Much important scientific research takes place outside laboratories but this work is not always recognised by historians of science. An expert on the topic argues why equal attention must be given to other sites in one of our features this week, says Ellie Bothwell, International reporter and global rankings editor at Times Higher Education.

Much important scientific research takes place outside laboratories. The history of science can only be enriched, argues Vanessa Heggie, lecturer in the history of medicine and science at the University of Birmingham, if we give equal attention to other sites.

If you do an image search for the word “scientist”, the results are extraordinarily standardised. Not only are most of the scientists themselves white and male, but they will also be in white coats, at a laboratory bench, looking down a microscope or peering at some glassware.

There have been important efforts to diversify the images of scientists. Yet it’s equally vital that we diversify our images of scientific activity. And we simply cannot understand how science operates if academic studies continue to ignore the vast amounts of work done away from the lab bench. 

When I was researching my first book, A History of British Sports Medicine (2011), I was surprised to find almost no scholarship on the history of 20th-century physiology. Part of the motivation for my new book, Higher and Colder: A History of Extreme Physiology and Exploration, was a desire to fill in some of the gaps.

Physiology was neglected for two related reasons: it was often a field-based, non-laboratory form of science – and it was not genetics or molecular biology.

The story of the 20th-century life sciences is dominated by the molecular revolution and genetics, and by an overall narrative – at least in our introductory undergraduate classes – that emphasises experimental “big science”. Although historians have argued that there was not really a scientific revolution in the 16th and 17th centuries, the rise and eventual dominance of experimental practice is a canonical part of the history of modern Western science...

There is one final hidden truth revealed by field science: a lot of scientific work is boring and repetitive. Whether it is hours of pipetting tiny aliquots of liquid (one of the reasons I left the discipline of genetics) or struggling to fill in sleep record cards while wearing thick gloves in the Antarctic desert, many of the essential tasks are physically challenging, tiring or numbingly routine. Although being in the Arctic or halfway up Everest might add a little heroic glamour to the activity, physiologists in these places found themselves overwhelmed by paperwork and disappointed in their food, much like a laboratory scientist with a dull university canteen.

Friends of S.T.E.A.M. rolling ahead with programs | Community - Garden City News

A Garden City-based nonprofit focusing on Science, Technology, Engineering, Arts and Mathematics has high hopes for partnerships and speakers to engage Garden City students this year by Rikki N. Massand, News and Education Writer, The Garden City News.


Garden City Friends of STEM was started in 2015 and is an active 501(c)3 nonprofit; this year the “A” was recently added to include the arts as in S.T.E.A.M.

The Friends’ founder and grants administrator is village resident Patricia Lynch. Matthew Wakeham is a Garden City resident, an experienced electrical engineer engineering, project consultant and factory automation engineer. In the community he is executive director of the Garden City Friends of STEAM.

At the organization’s meeting at the Garden City senior center on October 1, Wakeham spoke about the record number of sign-ups from this school year’s back-to-school nights in the district.

“We received pages and pages of parents’ signing up, especially from parents of students at the lower grade levels at Locust, Hemlock and Homestead schools. Accordingly, we had presented data from the World Economic Forum that states that 65% of students at primary schools are eventually going to work in jobs that do not exist yet. This aspect is an introduction to our discussions on technology and future applications,” he explained.

The Friends discussed a recent report produced by the Council on Foreign Relations covering “Innovations and National Security” and ways of America “keeping our edge” as emerging technology and strong S.T.E.M. programming for young students is necessary for long-term economic and national security...

Wakeham noted that in prior years, Computer Science participation was heavy in Garden City Middle School and Garden City High School, but some parents and the Garden City Friends of S.T.E.A.M. felt not enough had been done for lower grade levels and for girls to participate. He and his wife Tiffany met with Dr. Cannone and brought up the idea of a Garden City “Girls Who Code” chapter, and this year high school girls in the district plan on meeting with Dr. Melikian to discuss a Girls Who Code club.
With AP Computer Science taught by a woman, Diana Young, who also teaches Algebra 1 and 2, there is more leadership among women in technology in place in Garden City Schools. And both Lauren Maguire and Dr. Melikian serve as administrative role models in Computer Science and Technology.

- Free platform creates a virtual global community
- Encourages learning around UN Sustainable Development Goals for 2030
- Collaboration with Tribal Planet for platform focused on girls aged 13-18
- Initially connects more than 6,000 girls in Delhi schools; Atlanta and Seattle to follow

EY today announced the development of a mobile platform in collaboration with Tribal Planet to help girls 13-18 years of age pursue STEM (science, technology, engineering and mathematics) careers, as PRNewswire reports. 


The EY STEM Tribe platform engages girls on their mobile devices with an entertaining and gamified STEM experience and was developed working with Tribal Planet, a Silicon Valley-based company that develops innovative platforms and ecosystems to engage global citizens around social impact priorities. The app is available for free on Android and iOS platforms in Delhi and will be available in Atlanta and Seattle in the future.

The EY STEM Tribe platform features modules focused on science, such as climate change or space exploration; technology, such as artificial intelligence, 3D printing or blockchain; the future of work and skills that may be required for future, yet-to-be-defined jobs; and inspirational stories of women in STEM.

Rajiv Memani, Chairman and EY India Regional Managing Partner, says:
"As technology continues to shape the future, it has become imperative to provide equal opportunity for girls to pursue high-growth STEM careers. We are pleased to launch this global initiative in India that will enable STEM learning for 6,000 girls across 45 private and government schools in the Delhi National Capital Region, which has the potential to scale rapidly, empowering young girls to learn STEM in a pragmatic and contemporary manner."

Girls choose topics based on their interests. To help incentivize learning, they earn points as they complete an activity, such as reading an article, interviewing members of their community, completing an experiment or watching a video...

The EY Women in Technology Program was formed to create an inclusive culture to successfully harness technology's potential to truly transform society. By educating women and girls, incubating their leadership potential and innovating new ways to empower a diverse workforce, the EY organization supports the closing of the gender gap and nurturing an environment where everyone can become an architect of the transformative age. EY teams support women in tech through education by investing in educational products and programs that drive awareness and participation that encourage girls and women to enter and remain in STEM fields of study and careers.
