Silicon Nitride Ceramic:

Vacuum is a concept in physics. It initially reflects the state of nothingness, similar to "nothing". In the 20th century, P.A.M. Dirac put forward the concept of so-called quantum vacuum, High Precision Scribing Ceramic Substrate Sheet Thin Plate that is, vacuum is not nothing but the transformation of virtual particles and physical particles at all times, but the whole is a macroscopic totality with no physical properties. A vacuum is a sea of energy, an objective existence filled with huge energy that constantly oscillates; while space is only a mathematical concept that reflects the Alumina Ceramic Rod attributes of motion and the concept Alumina Ceramic Tube of geometric dimensions. In other words, space and vacuum are a mathematical concept and the other is a physical concept, and the two have no inclusive relationship. The properties of vacuum do need to be described by space, but that is only a mathematical expression, a parameter introduced for the convenience of research, not to say that the properties of vacuum depend on space. Mankind’s understanding of vacuum has undergone several fundamental changes and repetitions. The atomism of Democritus in ancient Greece believed that all matter is made up of atoms, and that outside the atoms is nothingness. In the 17th century, R. Descartes put forward the theory of etheric vortex, thinking that space is full of ether and used to explain the motion of planets. Soon I. Newton established Newtonian mechanics based on the three laws of motion and the law of universal gravitation, and successfully solved the problem of planetary motion around the sun. Gravitation is Alumina Ceramic Bar considered to act at a distance and does not require the sun as a transmission medium, thus negating the theory of ether. The volatility of light was discovered in the 19th century, and it was believed High Precision Scribing Ceramic Substrate Sheet Thin Plate that the propagation of waves High Precision Scribing Ceramic Substrate Sheet Thin Plate must rely on the medium, especially when the volatility of electromagnetic fields was discovered later. The ether theory emerged again. It is believed that any object in the universe is filled with ether, light and Electromagnetic waves are interpreted as mechanical vibrations of the ether. Later, although there was a change in concept, the light and electromagnetic waves were regarded as the vibration of the electromagnetic field, but the ether still retained some absolute properties, and it could be regarded as the absolute static reference frame describing the motion of all things.
