Solar plane lands in New York City

A solar-powered airplane finished crossing the United States on Saturday, landing in New York City after flying over the Statue of Liberty during its historic bid to circle the globe, the project team said.  The spindly, single-seat experimental aircraft, dubbed Solar Impulse 2, arrived at New York's John F. Kennedy International Airport at about 4 a.m. local time after it took off about five hours beforehand at Lehigh Valley International Airport in Pennsylvania, the team reported on the airplane's website.  Such a pleasure to land in New York! For the 14th time we celebrate sustainability," said the project's co-founder Andre Borschberg on Twitter after flying over the city and the Statue of Liberty during the 14th leg of the trip around the globe. The Swiss team flying the aircraft in a campaign to build support for clean energy technologies hopes eventually to complete its circumnavigation in Abu Dhabi, where the journey began in March 2015.

Sir William Ramsay


Born in Glasgow in October 1852, Ramsay was the only son of an engineer and businessman. He began his education in Glasgow Academy, which was followed by studies at the University of Glasgow. His initial interest in chemistry began when he first read about gunpowder in a book. He started attending lectures in the subject and even worked as an apprentice in the laboratory of the city analyst Robert Tatlock.
Ramsay went on to become a student of Rudolf Fittig, an organic chemist in the University of Tubingen in Germany. Here he received his doctorate for his thesis on investigations on the toluic and nitrotoluic acids. Following this, Ramsay returned to his hometown to become an assistant of Thomas Anderson at Anderson College. Ramsay went on to become the principal at the University College of Bristol, where he conducted research in the field of organic chemistry and gases.

Contributions to chemistry

Ramsay has made many contributions to the field of chemistry. His contributions touch the fields of organic chemistry and physical chemistry including stoichiometry, thermodynamics, molecular weights, density, surface tension and the critical states of liquids & 
 vapours. Lord Rayleigh, while conducting experiments discovered that when you got nitrogen from ammonia it was less than the nitrogen in air. And when Ramsay heard this he thought that there may be another gas involved. By with further experimentation he discovered a denser, inert gas which he called argon. In 1895, Ramsay along with fellow scientist Morris W Travers, discovered the gases Krypton, Neon and Xenon. Ramsay won the Noble Prize in 1904 for the discoveries of these invert gases.
