Iridium has several isotopes, with the two most stable and naturally occurring ones being: 1. **Iridium-191 (Ir-191)**: This isotope has a half-life of about 19.17 hours and decays to stable osmium-191. It is a product of the decay of heavier elements and is not found in significant amounts in nature.

Nobelium (No) is a synthetic element with the atomic number 102. It has no stable isotopes, and its isotopes are all radioactive. The most commonly referenced isotopes of nobelium are: 1. **Nobelium-254 (No-254)**: This is the most stable isotope of nobelium, with a half-life of about 55 minutes.

Promethium (Pm) is a rare and radioactive element with the atomic number 61. It has a number of isotopes, most of which are unstable and radioactive. The most notable isotopes of promethium include: 1. **Promethium-145 (Pm-145)**: This isotope has a half-life of about 17.7 hours and decays into Neodymium-145.

Seaborgium (Sg) is a synthetic element with atomic number 106. It is part of the transactinide series and was first synthesized in 1974. Due to its very short half-life, seaborgium has no stable isotopes. The known isotopes of seaborgium are all radioactive.

Zinc has several isotopes, but the most notable ones are: 1. **Zinc-64 (Zn-64)**: This is the most abundant isotope of zinc, making up about 48.6% of natural zinc. It has 30 protons and 34 neutrons. 2. **Zinc-66 (Zn-66)**: This isotope constitutes about 27.9% of natural zinc and has 30 protons and 36 neutrons.

"Italia in Miniatura" is a miniature park and tourist attraction located in Rimini, Italy. Opened in 1970, the park features scaled-down replicas of famous Italian landmarks and monuments, showcasing the country's rich architectural and cultural heritage. The models are built to a 1:25 scale and include various significant sites, such as the Colosseum in Rome, the Leaning Tower of Pisa, Venice's St. Mark's Basilica, and many others.

The Jacobi–Anger expansion is a mathematical identity that expresses the exponential function of a complex argument in terms of Bessel functions of the first kind. Specifically, it characterizes the relationship between the exponential function and the Bessel functions when the argument of the exponential function is a complex variable.

Jacques Dubochet is a Swiss biophysicist known for his pioneering work in the field of cryo-electron microscopy, a technique that allows researchers to visualize biological molecules in their native state at high resolution. In 2017, he was awarded the Nobel Prize in Chemistry, along with Joachim Frank and Richard Henderson, for their contributions to the development of cryo-EM, which has significantly advanced our understanding of the structure and function of biomolecules.

James Ax is a fictional character, a name, or a reference that may appear in various contexts, such as literature, films, games, or other forms of media. However, without more context, it is difficult to determine who or what "James Ax" specifically refers to.

Mathematical institutes are specialized research organizations or academic institutions focused on the study and advancement of mathematics. These institutes often conduct research, provide resources and support for mathematicians, promote mathematical education, and foster collaboration among researchers and practitioners. They may also host workshops, seminars, and conferences, and publish research findings in mathematical journals.

James Hansen is a prominent American climate scientist and an influential figure in the field of climate change research. Born on March 29, 1941, he is best known for his work on climate modeling and his early advocacy for the issue of anthropogenic (human-caused) global warming. Hansen gained widespread recognition after he testified before the U.S. Congress in 1988, where he warned about the potential impacts of climate change and urged immediate action to address it.

James Jurin was a notable figure in the field of medicine and science during the 18th century. He is best known for his work in the study of blood circulation and his contributions to the field of meteorology. One of his most significant contributions was in relation to the understanding of the principles of blood pressure and its measurement, which laid the groundwork for future developments in physiology.
