who has the highest h index in the world
h-index Among the 22 scientific disciplines listed in the Thomson Reuters Essential Science Indicators Citation Thresholds [thus excluding non-science academics], physics has the second most citations after space science.[14] During the period January 1, 2000 â€“ February 28, 2010, a physicist had to receive 2073 citations to be among the most cited 1% of physicists in the world.[14] The threshold for space science is the highest (2236 citations), and physics is followed by clinical medicine (1390) and molecular biology & genetics (1229). Most disciplines, such as environment/ecology (390), have fewer scientists, fewer papers, and fewer citations.[14] Therefore, these disciplines have lower citation thresholds in the Essential Science Indicators, with the lowest citation thresholds observed in social sciences (154), computer science (149), and multidisciplinary sciences (147).[14]
The World's Billionaires In the 32nd annual Forbes list of the world's billionaires, the gap between the top one percent and the rest of the billionaires continued to widen with the 20 richest people on the planet worth $1.2 trillion that amounts to 13 percent of all billionaires' fortunes combined.[2] A record of 2,208 billionaires were in the ranking and the total wealth was $9.1 trillion, up 18% since 2017. For the first time, Jeff Bezos was listed as the top billionaire due to Amazon's rising stock price that resulted in one person's biggest one year gain in wealth ($35 billion) since Forbes started tracking in 1987.[2] The U.S. continued to have the most billionaires in the world, with a record of 585, while China is catching up with 476 (when including Hong Kong, Macau and Taiwan).[2]
