Iron-55 (Fe-55) is a radioactive isotope of iron. It has a nuclear mass number of 55, meaning it has 26 protons and 29 neutrons in its nucleus. Iron-55 is produced as a decay product of manganese-55 and can also be formed in nuclear reactions. The half-life of Iron-55 is about 2.

Krypton-85 (Kr-85) is a radioactive isotope of the element krypton, which is a noble gas. It has a mass number of 85, meaning it has 36 protons and 49 neutrons in its nucleus. Krypton-85 is produced naturally in the atmosphere through the interaction of cosmic rays with stable krypton isotopes and is also released into the environment from certain human activities, primarily from nuclear reactors and radiological applications.

Uranium-234 (U-234) is an isotope of uranium, which is a heavy metal known for its use in nuclear fuel and weapons. U-234 is a radionuclide, meaning it is radioactive and undergoes decay over time. It has a relatively long half-life of about 245,500 years, which allows it to exist in significant quantities in nature, albeit at low concentrations.

Uranium-236 (U-236) is a radioactive isotope of uranium. It is one of the isotopes that can be produced through the capture of neutrons by uranium-235 (U-235), which is a more abundant isotope commonly used in nuclear reactors and weapons. U-236 has a relatively low occurrence in nature and is generally the result of nuclear reactions, such as those that occur in nuclear reactors or during the detonation of nuclear weapons.

Louis Guttman (1920–2014) was a prominent American sociologist and psychometrician known for his contributions to the fields of sociology, statistics, and measurement theory. He is best known for developing the Guttman scale (also known as the cumulative scale), which is a unidimensional scale used to measure a person's attitudes, opinions, or behaviors.

Michael Lin is an American mathematician known for his work in the field of number theory, particularly in relation to modular forms and algebraic geometry. He has made contributions to various areas, including arithmetic geometry and the study of automorphic forms. Lin has also been involved in various mathematical research projects and educational initiatives.

Mikhail Samuilovich Livsic (also known as Mikhail Livsic) is a notable mathematician known for his contributions to various areas in mathematics, particularly in the fields of dynamical systems, topology, and the theory of differential equations. His work has influenced both theoretical aspects of mathematics and applications in other scientific disciplines.

Moshé Machover is an Israeli philosopher and mathematician known for his contributions to the philosophy of mathematics and political activism. He has been a vocal critic of Israeli policies, particularly regarding the Israeli-Palestinian conflict. Machover is associated with leftist and Marxist movements and has participated in various political efforts advocating for justice and peace in the region. In the realm of mathematics, he has made significant contributions, though he is perhaps more widely known for his political writings and viewpoints.

Naum Meiman is a notable Russian-born American mathematician, primarily known for his contributions to various areas of mathematics, including number theory, mathematical logic, and set theory. His work has had an impact on both theoretical and applied mathematics. However, it is worth noting that details about particular mathematicians can sometimes overlap, and specific contributions might vary.

Oded Regev is an Israeli computer scientist known for his contributions to the fields of theoretical computer science, cryptography, and quantum computing. He is particularly recognized for his work on lattice-based cryptography, which is a field of encryption that relies on the mathematical structure of lattices in higher-dimensional spaces. This area of research is significant for developing cryptographic systems that are believed to be resistant to attacks by quantum computers.

The "Samson Option" refers to an alleged Israeli military strategy regarding its nuclear arsenal. The term is derived from the biblical figure Samson, who destroyed a temple and killed himself along with his enemies, symbolizing a last-resort option of massive retaliation. In the context of Israel, it implies that if the state were ever faced with an existential threat, it might resort to using its nuclear weapons as a means of ensuring that any adversary that attacked Israel would also face catastrophic consequences.

As of my knowledge cutoff in October 2021, Shaul Foguel does not appear to be a widely recognized figure in public discourse, academia, or popular culture. It is possible that he is a private individual, or perhaps has become notable after my last update.

David Horn is an Israeli physicist known for his contributions to various fields of physics, including condensed matter physics and surface science. He has been involved in research related to the properties of materials and has published numerous papers in his area of expertise.

Doron Gepner is a mathematician known for his contributions to the field of mathematics, particularly in areas such as algebraic geometry and topology. He has co-authored various mathematical papers and might be associated with research in specific mathematical theories or concepts. However, specific details about his work or background would require more context, as there may be limited publicly available information about certain researchers.

Nuclear weapons are explosive devices that derive their destructive power from nuclear reactions, either fission (the splitting of atomic nuclei) or fusion (the combining of atomic nuclei). These weapons have devastating effects, including massive explosive yields, intense heat, and lethal radiation. Israel is widely believed to possess nuclear weapons, although it has not officially confirmed or denied this status and follows a policy of ambiguity regarding its nuclear capabilities.

Jacob Israelachvili is a prominent scientist known for his contributions to the fields of surface and colloid science, as well as tribology (the study of friction, wear, and lubrication). He is best known for developing techniques and instruments to study intermolecular and surface forces at a molecular level, particularly through the use of the Surface Forces Apparatus (SFA).

As of my last knowledge update in October 2023, there isn't widely available information on a person named Jay Fineberg that is particularly notable or well-known in popular culture, academia, or public events. It's possible that he is a private individual or a professional in a specific niche not covered in prominent sources.

Yaron Oz appears to be a relatively obscure term or name, and as of my last knowledge update in October 2023, there is no widely recognized figure, concept, or entity by that name. It is possible that Yaron Oz could refer to a person, organization, or even a term that has emerged more recently or is specific to a niche context.

Italian bioinformaticians are scientists or researchers from Italy who specialize in the field of bioinformatics, which is the application of computational techniques and tools to understand biological data.
