This issue of CI describes several aspects of the Periodic Table, its history and celebra- tion, and also addresses the pathways to possible new elements. In this preface we address some highlights of the papers and pay attention to the history of events that have led to IYPT2019. In July 2016, professor Martyn Poliako hinted that in 2019 the Periodic Table would celebrate its 150th anni- versary, and the ball started to roll. On 30 September 2016, 3000 participants of the 20th Mendeleev Con- gress, held in Ekaterinburg, Russia, unanimously vot- ed for the proclamation of the International Year of the Periodic Table (IYPT) in 2019.

This is true also for countries that are rich in natural resources, but do not use them wisely. People that live in countries that enjoy high standard of living are industrious and their countries industrial. The basic reason of this division is technological entrepreneurship nourished by free market economy. Technologically entrepreneurial people make the difference. So, is there hope for everybody on the globe to improve their lives? Can technological entrepreneurship be motivated and taught so that generations of determined entrepreneurs will build up thriving economies? The clear answer to both questions is yes, but the process will take time and dedication. It all starts with education in general and scientific- technical education in particular. There is also a way to expedite the process – start with the already educated engineers and scientists. These are the first candidates for entrepreneurial endeavors. They can do it, but need motivation, continuous instruction and encouraging economic environment until they create successful start-ups and serve as role models for others. The name of the game is motivation.

The other elements carry the international discovering team around Sigurd names Bohrium (element 107), Hassium (element Hofmann at the GSI Helmholtzzentrum. The team 108), Meitnerium (element 109), Darmstadtium had suggested "Cp" as the chemical symbol for the (element 110), and Roentgenium (element 111). 21 new element. However, since the chemical symbol scientists from Germany, Finland, Russia, and "Cp" gave cause for concerns, as this abbreviation Slovakia collaborated in the GSI experiments that also has other scientific meanings, the discoverers lead to the discovery of element 112. and IUPAC agreed to change the symbol to "Cn". Copernicium is 277 times heavier than hydrogen, More information: 'Copernicium' proposed as making it the heaviest element officially recognized name for newly discovered element 112 -- by IUPAC. www.physorg.com/news166791177.html The suggested name "Copernicium" in honor of Nicolaus Copernicus follows the tradition of naming chemical elements after merited scientists. IUPAC Provided by Helmholtz Association of German officially announced the endorsement of the new Research Centres element's name on February 19th, Nicolaus Copernicus' birthday. Copernicus was born on February 19, 1473 in Toru?, Poland. His work in the field of astronomy is the basis for our modern, heliocentric world view, which states that the Sun is the center of our solar system with the Earth and all the other planets circling around it. An international team of scientists headed by Sigurd Hofmann was able to produce the element copernicium at GSI for the first time already on February 9, 1996.

  • Nfap Policy Brief » October 2019
    NATIONAL FOUNDATION FOR AMERICAN POLICY NFAP POLICY BRIEF» OCTOBER 2019 IMMIGRANTS AND NOBEL PRIZES : 1901- 2019 EXECUTIVE SUMMARY Immigrants have been awarded 38%, or 36 of 95, of the Nobel Prizes won by Americans in Chemistry, Medicine and Physics since 2000.1 In 2019, the U.S. winner of the Nobel Prize in Physics (James Peebles) and one of the two American winners of the Nobel Prize in Chemistry (M. Stanley Whittingham) were immigrants to the United States. This showing by immigrants in 2019 is consistent with recent history and illustrates the contributions of immigrants to America. In 2018, Gérard Mourou, an immigrant from France, won the Nobel Prize in Physics. In 2017, the sole American winner of the Nobel Prize in Chemistry was an immigrant, Joachim Frank, a Columbia University professor born in Germany. Immigrant Rainer Weiss, who was born in Germany and came to the United States as a teenager, was awarded the 2017 Nobel Prize in Physics, sharing it with two other Americans, Kip S. Thorne and Barry C. Barish. In 2016, all 6 American winners of the Nobel Prize in economics and scientific fields were immigrants.
