Gilbert Baker, designer of the Pride Flag, has passed away today at 65 years of age

Recently honored in the ABC series “When We Rise”, the openly gay artist is remembered for designing the unifying symbol of the LGBT community and movement. 

The rainbow flag was first designed and handmade in 1978. A rainbow was used to reflect the fact that LGBT people are of natural beauty. The first flag was flown on June 25, 1978 at San Francisco Pride, with 8 colors. Each had its own meaning: hot pink for sexuality, red for life, orange for healing, yellow for sunlight, green for nature, turquoise for magic/art, blue for harmony, and violet for the spirit. Following the assassination of influential leader Harvey Milk, the flag was in high demand and was revised to retain efficiency. Nowadays, the flag is shown as having 6 evens colors, having dropped hot pink and turquoise.

Now we must remember Mr. Baker as designing the seminal symbol for our people. Gone are the days of the pink triangle–we define ourselves. Thank you for giving us this beautiful symbol. The Pride Flag is something that has given us the image for our pride and community. There is nothing I would rather assign myself to more than the rainbow. We will always remember you.

Vera Rubin Who Confirmed “Dark Matter” Dies

Monday, December 26, 2016

Washington, DC–

Renowned astrophysicist and National Medal of Science awardee Vera Rubin passed away in Princeton N.J., the evening of December 25, 2016, at the age of 88. Rubin confirmed the existence of dark matter—the invisible material that makes up more than 90% of the mass of the universe. She was a retired staff astronomer at the Carnegie Institution’s Department of Terrestrial Magnetism in Washington, D.C.

“Vera Rubin was a national treasure as an accomplished astronomer and a wonderful role model for young scientists,” remarked Carnegie president Matthew Scott. “We are very saddened by this loss.”

In the 1960s, Rubin’s interest in how stars orbit their galactic centers led her and colleague Kent Ford to study the Andromeda galaxy, M31, a nearby spiral. The two scientists wanted to determine the distribution of mass in M31 by looking at the orbital speeds of stars and gas at varying distances from the galactic center. They expected the speeds to conform to Newtonian gravitational theory, whereby an object farther from its central mass orbits slower than those closer in. To their surprise, the scientists found that stars far from the center traveled as fast as those near the center.

After observing dozens more galaxies by the 1970s, Rubin and colleagues found that something other than the visible mass was responsible for the stars’ motions. Each spiral galaxy is embedded in a “halo” of dark matter—material that does not emit light and extends beyond the optical galaxy. They found it contains 5 to 10 times as much mass as the luminous galaxy. As a result of Rubin’s groundbreaking work, it has become apparent that more than 90% of the universe is composed of this invisible material. The first inkling that dark matter existed came in 1933 when Swiss astrophysicist Franz Zwicky of Caltech proposed it. But it was not until Rubin’s work that dark matter was confirmed.  

Besides her remarkable scientific contributions, as noted by colleague Neta Bahcall of Princeton University: “Vera was an amazing scientist and an amazing human being.  A pioneering astronomer, the ‘mother’ of flat rotation curves and dark-matter, a champion of women in science, a mentor and role model to generations of astronomers.”

She was an ardent feminist, advocating for women observers at the Palomar Observatory, women at the Cosmos Club, Princeton, and she even advised the Pope to have more women on his committee.

Rubin was born July 23, 1928. She arrived at Carnegie’s Department of Terrestrial Magnetism in Washington, D.C., in 1965. A Washington native, she graduated from Calvin Coolidge High School and went on to receive her B.A. from Vassar College. She obtained her M.A. from Cornell University and her Ph.D. from Georgetown University, where she then taught for 10 years. Rubin was the first woman allowed to observe at the Palomar Observatory.

In 1993 Vera Rubin received the National Medal of Science—the nation’s highest scientific award. She was elected to the National Academy of Sciences in 1981, and in 1996 became the first woman to receive the Royal Astronomical Society’s Gold Medal since Caroline Hershel, who was awarded the prize in 1828. Rubin’s husband Robert J. Rubin, a mathematician and physicist, died in 2008. The couple’s four children all acquired Ph.Ds. in the sciences or mathematics: David Rubin is a geologist; Judy Young, who died in 2014, was an astronomer; Karl Rubin is a mathematician; and Allan Rubin is a geologist.

Astronaut and Senator John Glenn, 7/18/1921 - 12/08/2016

We are saddened to learn of the passing of Astronaut and Senator John Glenn earlier today.  Glenn was the first American to orbit the Earth aboard Friendship 7 as one of @nasa’s original “Mercury Seven” astronauts, served as a United States Senator from Ohio from 1974 - 1999, and was the oldest human to go into space aboard the Space Shuttle Discovery mission STS-95 in 1998 at age 77.

Darren Seals, a prominent Ferguson, Missouri, activist, was found shot to death inside a burning car Tuesday morning, The 29-year-old’s body was found inside the charred vehicle on Diamond Street, 12 miles from where he lived, after the flames were extinguished. 

Seals’ death is being investigated as a homicide. According to the Times, Seals led protests with the activist group Hands Up United. Seals was oftentimes critical of the Black Lives Matter movement.Described as an assembly line worker and hip-hop artist by the Washington Post in a 2014 profile, Seals was active on Twitter under the username King D Seals, often tweeting about police brutality. Very recently, Seals had spoken out on the Kaepernick controversy.
