The neutron electric dipole moment (nEDM) )

A concise introduction and explanation of the different experimental techniques used in the study of neutron EDM is provided in this research work. These techniques include the room-temperature experiment, Ramsey’s technique and the mercury magnetometer. A brief discussion of the prevailing systematic uncertainties such as the geometric phase effect is also included. A recent neutron EDM experiment, which is more sensitive and still in progress is also incorporated and detailed in this study.
For over 50 years, the quest for an electric dipole moment (EDM) of a neutron has been a great endeavour in the field of physics.3 4 5 Ramsay’s search for a permanent EDM in the 1950’s leads the way to what seems to be an endless pursuit. Experimental sensitivity has increased significantly; in fact it improved by more than 106 factor.6 An impressive breakthrough in improving the experimental sensitivity, accountable for every eight years or so, is shown in Figure 1.7 Despite such remarkable accomplishment, there was no EDM ever observed.
The reason for this apparently obsessive behavior by a small group of dedicated physicists is that the observation of a nonzero neutron EDM would be evidence of time reversal violation and for physics beyond the so-called standard model of electroweak interactions. An essential point is that the standard model predictions of the magnitude of time reversal violation is inconsistent with our ideas of the formation of the universe; namely, the production of the presently observed matter-antimatter asymmetry requires time reversal violation many orders of magnitude greater than that predicted by the standard model.
According to Steven Weinberg, the electric dipole moments may offer one of the most thrilling prospects for progress in particle physics; a bright future awaits prospective experiments because ...Show more

Electric dipole moments of elementary particles
To be able to understand its nature would impact comprehension of the nature of both the electro-strong and weak forces. For half a century now, the quest for an EDM of elementary particles has been a great endeavour in the field of physics.1 2 3 The search for a permanent EDM in the 1950’s leads the path to what seems to be a pursuit for something unsure and endless.

A Life-Changing Moment
Change is the only constant thing that is applicable to everything and anything that exists in this world; at some point in time, everything experiences change. In essence, if change is not embraced, it will always find a way of occurring. The one thing about change is that it varies in magnitude.

Kairos moment
Kairos is a Greek term that is both flexible and multidimensional. It describes a rhetorical situation that happens in a given time and place. Therefore, there are kairotic moments in multiple activities e.g. to trade stock, sell or buy. This moment is an example of Kairos because it shows how a person can grab an opportunity in the ideal place and time to show the urgency or need to take an advantageous action.

Electric cars
Such cars are driven from a combination of dual fuel efficiency such as gasoline-electric or diesel-electric (Mom, 2012). Based on the conception of hybrid cars a car manufacturer present in Canada Ontario is about to come up with the idea of electric cars, which are completely electrical and not supposed to be supported by alternative fuel agents (gasoline or diesel).
