19th-century Dutch physicists

The 19th century was a significant period for physics in the Netherlands, with several notable Dutch physicists making important contributions to the field. Here are a few key figures and their contributions: 1. **Willem Einthoven (1860-1927)**: Although he worked into the early 20th century, Einthoven was a significant figure in late 19th-century physics.

C. H. D. Buys Ballot, or Christophorus Hubertus Dominicus Buys Ballot, was a Dutch meteorologist best known for formulating Buys Ballot's Law in the 19th century. Born on October 10, 1817, Buys Ballot made significant contributions to the study of meteorology, particularly in the understanding of wind patterns and atmospheric pressure.

Cornelis Wind doesn't appear to refer to a widely recognized figure, concept, or terminology as of my last training cut-off in October 2023. It's possible that it could be the name of a person, perhaps in a specific field or locality, or it might refer to a term or concept that has emerged after that date.

Hendrik Lorentz was a Dutch physicist who made significant contributions to theoretical physics in the late 19th and early 20th centuries. He is best known for his work on electromagnetism and his development of the Lorentz transformation, which describes how the measurements of time and space change for observers in different inertial frames of reference. This work was essential to the formulation of Einstein's theory of special relativity.

Johannes Bosscha was a notable Dutch astronomer and physicist, best known for his contributions to the field of astronomy in the late 19th and early 20th centuries. He played a significant role in the establishment of astronomical research and education in the Netherlands and was particularly associated with the development of the Bosscha Observatory in Lembang, Indonesia, which was named in his honor. The observatory became an important center for astronomical studies in the region.

Johannes Kuenen is not a widely recognized figure as of my last knowledge update in October 2023, so it's possible that you may be referring to a niche or less-known individual, or perhaps there has been a development after that date.

As of my last update in October 2023, Martin Hoek is not a widely recognized individual or term associated with significant events or phenomena. It is possible that he could be a private individual, a relatively obscure figure, or a topic that has gained relevance after my last update.

As of my last knowledge update in October 2023, there is no widely recognized individual or concept named "Pieter Rijke." It's possible that he could be a private individual, a professional in a specific field, or a public figure who emerged after that date.

Volkert Simon Maarten van der Willigen appears to be a person's name, but there is no widely known information or notable figure by that name in public records as of my last update in October 2023. It's possible that this could refer to a private individual or someone not in the public eye.
