July 23rd 1916 saw the death of Sir William Ramsay, Scottish chemist .
Ramsay was the only man to discover a complete Periodic Group of elements
He studied under Robert Wilhelm Bunsen, and predicted that dense gasses were hidden, invisible and as yet undetected in the Earth’s atmosphere. To test his idea, he designed an experimental means to remove oxygen and nitrogen from the air, and analyzing what remained in collaboration with Lord Rayleigh he found the previously unknown element argon in 1894.
He later spectroscopically confirmed the existence of helium, which had first been observed by Pierre Janssen. From the established positions of argon and helium on the periodic table of elements, Ramsay guessed that more unknown gasses exist, and discovered krypton, neon, and xenon in 1898.
Working with chemist Robert Whytlaw-Gray he discovered radon in 1900. In 1903, working with Frederick Soddy, Ramsay showed that the radioactive decay of radium produces helium, a discovery which laid the groundwork for the subsequent development of nuclear physics.
In 1904 he was awarded the Nobel Prize in Chemistry, while his colleague Rayleigh won the Nobel Prize in Physics in the same year. The document in the pics is his Noble Prize.

Explore some of the world’s best murals, courtesy of MSN!
Lonac, “Nitpicking” – Rijeka, Croatia
Croatian artist Lonac created this photorealistic mural of a man (his father) focused on the model of a ship for the MMSU Rijeka Spajalica public art project. He used around 100 cans of spray paint with some 50 different color tones and worked seven days to create this piece.
Hosier Lane – Melbourne, Australia
Perhaps one of the most famous street art locations in the world, Hosier Lane in Melbourne is essentially an open canvas, meaning that any artist can go and add to the murals. The result is an impressive mishmash of different styles. You can get lost in this eclectic lane and revisit many times, having a completely different experience each time.
Multiple artists – Incheon, South Korea
Incheon’s mural, painted over silos, is the largest outdoor mural in the world, according to Guinness World Records. The mural resembles a set of 16 books and shows the story of a boy growing into an adult.
Artist unknown, “I love you so much” – Austin, USA
Perhaps not an impressive street mural per se, this phrase, graffitied on the side of Jo’s Coffee on South Congress Avenue in Austin, Texas, has become one of the most famous pieces of street art in the world and an attraction in its own right. Apparently, the owners of the coffee shop, who are a couple, got into a fight and one of them painted this love declaration on the side of the building.
Petit Champlain Murals – Old Quebec, Canada
Old Quebec is known for its beauty, and the Petit Champlain trompe l’œil murals are no exception. The area between this neighbourhood and Parliament Hill is home to remarkable works of art, including Fresque du Petit-Champlain.
Muralis – Sherbrooke, Canada
The thing that makes Sherbrooke’s murals special is that Easter eggs are hidden in all of the paintings. Visitors to this city in Quebec are invited to try and find them thanks to an app—which also makes the murals come alive!
Guido van Helten, “No Exit” – Reykjavik, Iceland
Dmitri Vrubel, “My God, Help Me to Survive This Deadly Love” – Berlin, Germany
This political mural depicts a 1979 photograph where Leonid Brezhnev, the General Secretary of the Soviet Union, and Erich Honecker, the General Secretary of the Socialist Unity Party of the German Democratic Republic, share a socialist fraternal kiss.
It is located on the eastern side of the Berlin Wall and has become an emblem of the city.
Millo, “Everyone Is Searching for It” – Milan, Italy
Painted in 2015 and depicting a man searching for love in the big city using a fortune stick and a woman hopefully catapulting her heart, Millo’s Everyone Is Searching for It is a great example of the artist’s signature style.
Louis Gan, “Brother and sister having fun on the swing” – George Town, Malaysia
George Town is known for its street art (amongst many other things, of course) and this mural, Brother and sister having fun on the swing, is probably one of the city’s most photographed, because passersby can include themselves in the art!
Banksy, “Girl with Balloon” – London, UK
Arguably one of the most famous murals in recent years, Banksy’s Girl with Balloon was first painted on Waterloo Bridge in 2002, and other similar murals were also painted around London, although none remain today. In fact, in 2018, a framed copy of the painting spontaneously shredded while it was being auctioned, thanks to a mechanical device that the artist had hidden in the frame.
ChemiS, “House of Cards” – San Nicolas, Aruba
Painted as part of the Aruba Art Fair, ChemiS’s House of Cards takes up the whole façade of the Winter Garden bar restaurant and nightclub. Its trompe l’œil effect is really impressive!
Comic Book Route – Brussels, Belgium
In 1991, the City of Brussels authorities and the Belgian Comic Strip Center undertook the project of creating a comic strip route in the city of Brussels, covering up plain walls. The project has since grown to over 50 murals.
Belfast Murals – Belfast, Ireland
Northern Ireland has a complicated and tumultuous political and religious history and the Belfast Murals depict this, highlighting important moments and people of the last 40 years. One of the best ways to visit is with a black cab tour, to admire the works of art and learn about the local history.
El Mac & Gene Pendon, “Leonard Cohen” – Montreal, CA
Montreal is a city renowned for its street art and holds the annual Mural street art festival. In recent years, two gigantic murals honouring the late Canadian singer, songwriter, poet and novelist Leonard Cohen have sprung up on building façades. The most impressive one is located on Crescent Street and can be admired from the city’s Kondiaronk belvedere.
Keith Haring, “We the Youth” – Philadelphia, USA
Created in 1987 in collaboration with the CityKids Foundation and restored in 2013, We the Youth is the only Keith Haring mural that remains intact in its original site. The mural was painted to commemorate the 200th anniversary of the United States Constitution and is a play on the phrase “We the people.”
The mural is located at 22nd and Ellsworth Streets in Philadelphia, Pennsylvania.

Originally from Kazakhstan but now living in the Czech Republic, Dmitrij Proskin aka Chemis, first laid eyes on a graffiti magazine at age 16. He says his neighborhood was not happy with his new hobby but he was soon painting bigger and better work. Chemis started with classic lettering, stencil, and stickers—“just the usual night stuff” he told Street Art United States—but he was driven to paint larger and more meaningful work so soon moved to doing permissioned work and experimenting with photorealism and anamorphic 3D techniques. In 2013, for Baton Rouge’s Museum of Public Art, he collaborated with Pose 2 painting the side of the derelict but historically significant Lincoln Theater at 13th and Myrtle Walk Streets, and his lettering in this small exit alcove is a fascinating example of his precise anamorphic work. @chemisgraffiti @museumofpublicart Â
