From our previous analysis, given that v = 0.25 and c = 1, the equation of the dashed line of simultaneity is t − 0.25x = 0 and with v = 0, the equation of the dotted line of simultaneity is t = 0. In general the second observer traces out a worldline in the spacetime of the first observer described by t = x / v , and the set of simultaneous ...
As in the Bucherer-Neumann experiments, the velocity and the charge-mass-ratio of beta particles of velocities up to 0.75c was measured. However, they made many improvements, including the employment of a Geiger counter. The accuracy of the experiment by which relativity was confirmed was within 1%. [7]
Sir John Douglas Cockcroft (27 May 1897 – 18 September 1967) was an English nuclear physicist who shared the 1951 Nobel Prize in Physics with Ernest Walton for splitting the atomic nucleus, which was instrumental in the development of nuclear power.
Ernest Thomas Sinton Walton (6 October 1903 – 25 June 1995) was an Irish nuclear physicist and Nobel laureate in Physics who first split the atom. [1] He is best known for his work with John Cockcroft to construct one of the earliest types of particle accelerator, the Cockcroft–Walton generator.
The Cockcroft–Walton (CW) generator, or multiplier, is an electric circuit that generates a high DC voltage from a low-voltage AC. [1] It was named after the British and Irish physicists John Douglas Cockcroft and Ernest Thomas Sinton Walton, who in 1932 used this circuit design to power their particle accelerator, performing the first artificial nuclear disintegration in history.

In physics, relativistic mechanics refers to mechanics compatible with special relativity (SR) and general relativity (GR). It provides a non-quantum mechanical description of a system of particles, or of a fluid, in cases where the velocities of moving objects are comparable to the speed of light c.
A much more precise experiment of this kind was conducted by David H. Frisch and Smith (1962) and documented by a film. [8] They measured approximately 563 muons per hour in six runs on Mount Washington at 1917m above sea-level. By measuring their kinetic energy, mean muon velocities between 0.995 c and 0.9954 c were determined.
The developing precision and data analysis of these experiments and the resulting influence on theoretical physics during those years is still a topic of active historical discussion, since the early experimental results at first contradicted Einstein's then newly published theory (1905), [1] but later versions of this experiment confirmed it.
