Police today welcomed the Communications Authority’s decision that Radio Television Hong Kong (RTHK) should be seriously warned regarding complaints against an episode of its programme Pentaprism broadcast on November 20, 2019.

Police said it had taken note of the press release issued by the authority on April 20 about its decision.

The authority found that the host’s remarks made in the programme were irresponsible and could be regarded as hate speech with the effect of inciting hatred against Police.

The remarks were also unfair to and were capable of adversely affecting Police’s reputation.

The authority took the view that the complaints in respect of accuracy, incitement of hatred and fairness were substantiated and decided that RTHK should be seriously warned.

Since the anti-extradition bill protests in June last year, rumours have been circulating to defame and smear Police in an attempt to disrupt its relations with the community, the force said.

Police reiterated that they are willing to accept criticisms which are constructive and based on goodwill, but they do not accept inaccurate or misleading reports and remarks, and will follow up as appropriate.

The 2020 honours and awards selection and appointment of Justices of the Peace (JPs) exercise will be postponed, as well as the announcement of the list of honours and awards and JP appointments, the Government announced today.

It decided to defer the exercise to accord top priority to the ongoing anti-epidemic work and implementation of measures to retain employment, support businesses and ease people's livelihood in the face of challenges arising from the COVID-19 epidemic.

The Honours List and JP appointments will be announced on October 1 instead of July 1 as in previous years, the Government added.

Emily Riehl, Johns Hopkins University, received the university's $250,000 President's Frontier Award, whose purpose is to nurture individuals at Johns Hopkins University who are breaking new ground and poised to become leaders in their field. Riehl studies category theory and says that "I just thought the proofs were the most beautiful of any of the other areas I've encountered. ... It was sort of love at first sight and I am lucky to be able to do what I love." The award is considered a "$250,000 investment in doing more of what she loves."

The 2020 Mathematical Art Exhibition Awards were made at the Joint Mathematics Meetings last week "for aesthetically pleasing works that combine mathematics and art." The chosen works were selected from the exhibition of juried works in various media by over 90 mathematicians and artists from around the world.

"Suspended Helical Stair," by Mark Donohue (California College of the Arts, San Francisco, CA), was awarded Best textile, sculpture, or other medium. "A unique cable system to suspend a stair was developed in collaboration with a leading structural engineer. The suspended cables form a double helicoid nested within an ascending spiral hyperboloid to create the necessary points of support for the gravity loads and lateral bracing for the seismic loads. Each concrete stair tread was designed as an independent element that is strung together with the stairs above and below it to form a single spiral stair when the steel cables that run through them are post tensioned. The entire stair tread and suspension cable system can be understood as a play of ruled surfaces with each part related to the other through their shared geometric lineage." The work is string and plywood,45 x 23 x 23 cm, 2018.

"A Unit Domino," by Douglas McKenna (Mathemaesthetics, Inc., Boulder, CO), was awarded Best photograph, painting, or print. "This piece is based upon an artist-discovered "half-domino" space-filling curve. The drawing comprises some half-million connected line segments, arranged in two perfectly recursive levels of double-spiral pairs, slowly changing color, in a single, over-one-mile-long self-avoiding path from lower left to lower right (the lower right square that sticks out is an integral part of its self-negative structure). The limiting curve covers a self-similar gasket tile with an infinitely long, almost-everywhere linear border. With an upside-down copy of itself, two such gaskets of unit area exactly cover a 1x2 domino, without overlap. The artist's app/eBook "Hilbert Curves" for iPad/iPhone explains how he discovered these beautiful constructions." The work is a glicée print,106 x 66 cm, 2015.

"Computational Wings," by David Bachman (Pitzer College, Claremont, CA), received Honorable Mention. "The body of this dragonfly is taken from a photograph, while the wings were computationally generated. A variety of algorithms were used to create them. First, a set of points were randomly populated across each wing and moved by a circle packing algorithm, where the radius of each circle was inversely proportional to the distance from the body. Next, those points were used to create a Voronoi diagram. Main veins were located by a shortest walk algorithm through the edges of this diagram, and those veins were given a variable thickness according to the distance travelled as you traverse them outward from the body." The work is laser etched acrylic, 23 x 35 x 3 cm, 2019.

The Mathematical Art Exhibition Award "for aesthetically pleasing works that combine mathematics and art" was established in 2008 through an endowment provided to the American Mathematical Society by an anonymous donor who wishes to acknowledge those whose works demonstrate the beauty and elegance of mathematics expressed in a visual art form. The awards are $400 for Best photograph, painting, or print; $400 for Best textile, sculpture, or other medium; and $200 for Honorable Mention. The Mathematical Art Exhibition of juried works in various media is held at the annual Joint Mathematics Meetings of the American Mathematical Society (AMS) and Mathematical Association of America (MAA). a gallery of works in the 2020 exhibition will be on AMS Mathematical Imagery.

(Arizona State University) Gary Moore, assistant professor in ASU's School of Molecular Sciences and the Biodesign Institute's Center for Applied Structural Discovery has just been named one of 14 young faculty nationwide to be honored with a 2020 Camille Dreyfus Teacher-Scholar Award by the Camille and Henry Dreyfus Foundation.

With the northeast monsoon over southern China being generally weaker than normal for most of the time in March, the month was much warmer than usual, the Hong Kong Observatory said today.

The monthly mean temperature was 21.3 degrees Celsius, 2.2 degrees above normal and the mean minimum temperature was 19.7 degrees Celsius, 2.5 degrees above average. Both were the joint second highest on record for March.

The monthly mean maximum temperature was 23.8 degrees Celsius, 2.4 degrees above normal and the fifth highest on record for the month.

The month was also drier than usual with a total rainfall of 41.3mm, about half of the normal figure.

The accumulated rainfall recorded in the first three months of the year was 135.9mm, about 16% below average.
