Here is a realistic passage supporting the sentence:

In the late 19th century, Dutch physicist Jacobus Anthonie Meessen made a groundbreaking discovery that would forever change the field of atomic physics. While conducting experiments at the University of Leiden, Meessen observed that when atoms were placed in a magnetic field, their energy levels split, a phenomenon that would come to be known as the Meessen effect. Meessen's pioneering work, published in 1896, provided a fundamental understanding of the interaction between light and matter, paving the way for significant advancements in spectroscopy and quantum mechanics.

 In his later years , Teller became especially known for his advocacy of controversial technological solutions to both military and civilian problems , including a plan to excavate an artificial harbor in Alaska using thermonuclear explosive in what was called Project Chariot . He was a vigorous advocate of Ronald Reagan 's Strategic Defense Initiative . Throughout his life , Teller was known both for his scientific ability and his difficult interpersonal relations and volatile personality , and is considered one of the inspirations for the character Dr. Strangelove in the 1964 movie of the same name .
