Design: 20 Ft. Wide ‘Pencil Tower Hotel’ In Sydney
An improbably narrow, six meter wide site is envisaged for a 100m tower in the downtown area of Sydney near its central station.
Our proposal embraces this extraordinary attenuated quality, proposing a ‘column’ tower on a low scale podium.
The podium references the delicacy and detail of its heritage neighbours, using the language of grand arching brickwork. A three story urban room houses multiple levels of lobby, cafe & lounge, visible through a large scale keyhole window. A walled courtyard garden for shared use overlooks the street.
The tower simulates the compression and extension of a column, through a continuous abstraction of the elements of a column: base, shaft and capital.
The facade begins with compressed horizontal screening, slowly transforming into exaggerated verticals at the top. Horizontals begin wide and flush with the outside frame, slowly thinning and receding at the height of the tower. Each horizontal is at the height of the slab, handrail and door head height.
The capital is joyfully expressed as a flying balcony and shell curves of a rooftop sundeck, pool and “hammam” spa. The soffit of the curved ceiling is brightly tiled, visible from both the street below and the city beyond.
Each floor houses compact hotel rooms, gathering light from the street, rear court or internal shapely voids. The voids are tiled to reflect light and colour into the rooms. Key hole windows provide a framed vignette of the seamless tiled surface.
Testing the boundaries of construction and design, the ‘pencil’ tower adds both a generous street room and a heroic skyline to its neighbourhood.
Science Podcast: Social Costs Of Carbon & The Chirps Of Mole-Rats
On its first day, the new Biden administration announced plans to recalculate the social cost of carbon—a way of estimating the economic toll of greenhouse gases. Staff Writer Paul Voosen and host Sarah Crespi discuss why this value is so important and how it will be determined.
Next up, Alison Barker, a postdoctoral researcher at the Max Delbrück Center for Molecular Medicine, talks with Sarah about the sounds of naked mole-rats. You may already know naked mole-rats are pain and cancer resistant—but did you know these eusocial mammals make little chirps to identify themselves as colony members? Can these learned local dialects make naked mole-rats a new research model for language learning?

Arts Podcast: ‘Lives Of Leonardo da Vinci’ (Getty)
In this episode, Getty curator Davide Gasparotto discusses early accounts of Leonardo’s life and how they shaped our understanding of the artist. Passages from these biographies were recently collected in the Getty Publications book Lives of Leonardo da Vinci.
“He was a great artistic personality, crucial for the development, in some way, of what we think as the modern science. But he was not alone.”
Leonardo da Vinci died more than 500 years ago, but he is still revered as a genius polymath who painted beguiling compositions like the Mona Lisa, avidly studied the natural sciences, and created designs and inventions in thousands of journal pages. Even during Leonardo’s lifetime, contemporaries marveled at the artist’s great skill and wide-ranging pursuits, but many also noted his perfectionism and difficulty completing projects. Since his death, the legends surrounding his life and personality have continued to grow. Today Leonardo’s story inspires novels and his work brings record-breaking prices, demonstrating his enduring relevance and mystique.
Paintings: ‘The Son Of Man’ By Belgian Surrealist Rene Magritte In 1946 (Video)
The “Son of Man” is an iconic painting by Belgian Surrealist artist Rene Magritte.
Rene Magritte was an internationally acclaimed surrealist artist of all time, yet it was not until his 50s, when he was finally able to reach some form of fame and recognition for his work. Rene Magritte described his paintings saying, “My painting is visible images which conceal nothing; they evoke mystery and, indeed, when one sees one of my pictures, one asks oneself this simple question, ‘What does that mean?’ It does not mean anything, because mystery means nothing, it is unknowable.”
Magritte was born in 1898, to a wealthy manufacturer father. In 1912, his mom was found drowned in the River Sambre. She had committed suicide, and the family was publicly humiliated because of it. From 1916 to 1918, Rene decided to study at the Academie des Beaux-Art, which was located in Brussels. He left the school, because he thought that it was a waste of time. All his paintings afterward reflect cubism, the movements which were introduced by Pablo Picass and was very popular at the time. In 1922 he married Georgette, and took a number of small jobs, including painting cabbage roses for a wallpaper company, in order to be able to pay the bills.
During the early period of his career, shortly following his marriage, Rene Magritte would spend the free time that he had, creating art forms and worked on a number of pieces; it was during this time period that he realized surrealism was the art form which he most enjoyed. The Menaced Assassin was one of his earliest pieces in 1926, which showcased the surrealist style which he had been working on; The Lost Jockey was another piece that he introduced in 1925, which also showcased this art form. Over the course of his career, he produced a number of variants on this piece, and changed the format to recreate what the viewer was experiencing.
