With reference to the science of Nuclear Fusion versus Nuclear Fission, consider the following statements: 1. Nuclear fission involves splitting heavy atomic nuclei (such as Uranium-235), whereas nuclear fusion involves combining light atomic nuclei (such as Deuterium and Tritium). 2. Nuclear fusion produces long-lived, high-level radioactive transuranic waste requiring thousands of years of geological disposal. 3. The National Ignition Facility uses laser-driven inertial confinement fusion, unlike tokamak reactors which use magnetic confinement. Which of the statements given above are correct?

Consider the following statements regarding commercial semiconductor node designations: 1. The label '2 nm' or '0.7 nm' in modern semiconductor fabrication corresponds directly to the physical gate length of individual transistors. 2. Modern sub-3nm nodes increasingly utilize Gate-All-Around (GAA) nanosheets and 3D complementary FET (CFET) architectures. 3. Extreme Ultraviolet (EUV) lithography uses a light wavelength of approximately 13.5 nanometers to etch nanoscale circuit patterns. Which of the statements given above are correct?

With reference to the principles of Quantum Key Distribution (QKD) and quantum cryptography, consider the following statements: 1. QKD allows two parties to produce a shared random secret key known only to them to encrypt and decrypt messages. 2. The security of QKD relies on the fundamental laws of quantum mechanics, specifically the no-cloning theorem and Heisenberg's uncertainty principle. 3. An eavesdropper attempting to intercept quantum keys can do so undetected without introducing any measurable quantum disturbance. Which of the statements given above are correct?

Consider the following statements regarding the potential scientific applications of Thorium-229 Nuclear Clocks: 1. They provide dramatically higher resistance to external electromagnetic stray fields compared to optical atomic clocks. 2. They can be utilized to test whether fundamental constants of physics (such as the fine-structure constant) vary over time. 3. They require large steam turbines to operate and can only be housed inside coal-fired power stations. Which of the statements given above are correct?

With reference to the A.M. Turing Award, consider the following statements: 1.
