Neon, Rubik’s Cube

HKFP_Lens: Canadian photographer Greg Girard debuts a collection showing the underside of the city that he lived in for 15 years. From neon-lit streets in Tsim Sha Tsui to dive bars in Wan Chai to the hotel rooms of the soldiers and sailors who frequented them.
Neon is a chemical element with symbol Ne and atomic number 10. It is a noble gas.[10] Neon is a colorless, odorless, inert monatomic gas under standard conditions, with about two-thirds the density of air. It was discovered (along with krypton and xenon) in 1898 as one of the three residual rare inert elements remaining in dry air, after nitrogenoxygenargon and carbon dioxide were removed. Neon was the second of these three rare gases to be discovered, and was immediately recognized as a new element from its bright red emission spectrum. The name neon is derived from the Greek word, νέον, neuter singular form of νέος (neos), meaning new. Neon is chemically inert and forms no uncharged chemical compounds. The compounds of neon include ionic molecules, molecules held together by van der Waals forces and clathrates.
