Holm Gero Hümmler

Hümmler was born in Hanau. He studied physics[1][2][3][4][5] and meteorology[1][2][5][6] at Goethe University Frankfurt, together with economy at University of Hagen.[1][2][5] He was active in politics while at university.[7] While working on his diploma thesis he spent several months at CERN in Geneva, Switzerland.[1][2][4][6] He completed his PhD at Technical University of Munich in 2000.[4] He also worked at Max Planck Society, physics department.[1][2][4][6] Hümmler describes his field of physics as being between nuclear physics and particle physics.[7]

He participated in the STAR experiment at the Relativistic Heavy Ion Collider in Brookhaven National Laboratory, Upton, New York.[1][4][6] He left science in 2001 and first worked for Boston Consulting Group.[2] In 2007 he founded Uncertainty Managers Consulting. The company specializes in numerical models for business planning, mainly for the Pharmaceutical and Healthcare sector.[3]

He lives and works in Bad Homburg,[8] near Frankfurt am Main.

Hümmler has been active in the German skeptics' group GWUP since 1990s.[1] He was a regional spokesman and convenor for the Frankfurt area.[3] He first became interested in skepticism after reading about the European Skeptics Congress.[7] For several years he was an editor of The Skeptiker magazine.[9] He now investigates pseudoscience claims mostly from the areas of pseudo-physics, business esoterics, conspiracy theories,[2][3] supernatural claims in martial arts,[2][3][6][9] alleged UFO encounters,[5][6][9] weather effects,[5][9] biological influence of radiation,[5] misuse of physics terminology in pseudoscience, especially in Quantum Theory and Theory of Relativity,[9] debunking free energy theories[9] and quantum healing[3].

Hümmler appears in media as a GWUP expert commenting on conspiracy theories, such as chemtrails.[3] In 2008 he investigated the abilities of Shaolin monks on the Galileo Mystery TV show.[3]

In a German Physik Journal, an official journal of the Deutsche Physikalische Gesellschaft, which is the world's largest organization of physicists, Hümmler wrote an article calling physicists to take a stand against the esoteric abuse of science.[10]

His first book, Relativer Quantenquark, was published in April 2017. It deals with pseudo-physical claims in esoterics and alternative medicine, but it also explains the basics of quantum mechanics and relativity.[11][12] As of July 2017, Hümmler is working on a new book.[7]

Hümmler is an author of the science blog quantenquark.com.[3] He was a speaker at the 17th European Skeptics Congress in Wrocław, Poland, where he presented a speech titled Relative Quantum Nonsense: Don't be Fooled by False Physics.[3]
