One of the advanced inventions in physics is the concept of absolute temperature. It is a thermodynamic scale that is based on the properties of a system when all thermal motion has ceased. Absolute temperature is represented in kelvin (K) and is the measure of the average movement of particles in a system. This concept was first introduced by the British physicist William Thomson, also known as Lord Kelvin, in the mid-19th century.


Another advanced invention in physics is the quantum theory of radiation. This theory explains the behavior of electromagnetic radiation, which includes the properties of light and other forms of radiation. The theory was introduced by Max Planck, a German physicist, in 1900. Planck proposed that energy is not continuous but instead exists in small packets, which he called quanta. This idea revolutionized the way scientists thought about energy and laid the foundation for the development of quantum mechanics.


In summary, the concept of absolute temperature and the quantum theory of radiation are two advanced inventions in physics that have greatly impacted the field of science. Lord Kelvin introduced the concept of absolute temperature, which is a thermodynamic scale based on the properties of a system when all thermal motion has ceased. Max Planck introduced the quantum theory of radiation, which explains the behavior of electromagnetic radiation and laid the foundation for the development of quantum mechanics.
