<div style="direction: ltr; margin: 0px;"><span style="font-family: Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">One of the interesting issues in the philosophy of experiment is that
of the replicability of experimental results. The scientific community enthusiastically endorses the idea that “Replication – the confirmation of results and conclusions from one study obtained independently in another is considered the scientific gold standard.”
The underlying argument for this is that if an experiment has succeeded in revealing a real phenomenon or accurately measuring a quantity then that success should reappear when the experiment is repeated under the same circumstances or when it is reproduced
in a different experiment. There are, however, questions about whether this standard is universally, or even typically, applied. There are also questions concerning what constitutes a successful or failed replication.</span></div>

The discovery of the Higgs boson and the detection of gravitational radiation. Two failed replications will also be presented: early experiments on the Fifth Force, a proposed modification of Newton’s Law of Gravity; and attempts to measure G, the universal
gravitational constant in Newton’s law. More complex episodes in which the success or failure of replication was not clear will also be discussed. These include measurements of physical constants and claims of low-mass electron-positron states. The methods
used to resolve the issues in these more complex cases will also be discussed.</span></div>
