enhance Your English Vocabulary by Physics: ‘A’


It is imperative that Science students should have a sound knowledge of English when they learn Science, especially Physics when the medium of learning Is English. Un-fortunately, in India, that spirit is missing from students They think that learning language is not their concern and that it is enough they become tech-savvy. But this author strongly feels that students of Physics should have an excellent knowledge of English which will go a long way in improving and exhibiting their talents. There is an imperative need to enhance the vocabulary. For this, they need not go in search of various English text books. On the contrary, if they understand the literal equivalents of the technical terms their vocabulary will enhance a lot. With this intention, the author has ventured to select some technical words, which are not so shared in public use and give their literal and general applications. This is the first article in the series explaining a few words starting with the alphabet ‘A’.

1. Aberration:

This information is associated with Optics and Sound in Physics. The Scientific meaning of this information is non-convergence of light rays due to the time of action known as Chromatic aberration or difference of focus of marginal rays known as Spherical aberration.

This technical information is derived from the information ‘aberrate’, which method to wander or deviate from the right way.

E.g.: His sustain of Nazi front in II world war is an aberration in his otherwise patriotic character

The other Technical words related to this information are coma and astigmatism. The information ‘coma’ is commonly used in medical field as “The patient went into coma” meaning that the patient went into thorough unconsciousness while in Physics it method a clouded nebulous focusing of light.

The information ‘astigmatism’ method a defect in eye,lens or mirror, the information having been derived from stigma which method any special mark, usually having a negative meaning

E.g.: He is not given promotion because there is a stigma in his report.

The information aberration is used in sound also with the same meaning as in optics.

When a performer deviates from the normal observe (Wanders randomly) we call that there is an aberration. There is a beautiful Sanskrit equivalent for this information as found in ‘Apaswaram’ meaning that the observe is on the wrong side.

2. Accretion:

The scientific meaning is ‘mass accumulated by gravitational allurement as in the case of Black Hole etc.

Normal literal meaning is ‘continued external growth ‘ which is a derivation of the information accrescent which method ever increasing as in the case of phases of the moon which is known as crescent.

3.Adiabatic course of action:

Adiabatic course of action method any course of action that occurs without heat entering or leaving the system. Hence there is neither increase nor decline in temperature. In fact no heat energy passes ‘by’ the system.

The root of this information is ‘ dia’ which method to pass by. (Diameter is a straight line, passing by the central point). Hence adiabatic in Thermodynamics method no heat is passing by the system.


The dictionary meaning is ‘whiteness’, the proportion of light reflected by a planet giving it the whiteness we observe. The meaning credited in Physics is the ratio of the incident flux reflected by a surface to that falling on it. It also represents the Probability of reflection of a neutron reflected back from the very surface it entered. It may be noted that all the three meanings have only a little difference and the shared thing is whiteness retained.


Anemo method wind and anemometer is a measuring instrument for speed of wind. For that matter, any information with the prefix ‘anemo’ refers to wind only. Other examples are: anemographic, anemology, anemophily etc.


Aqua method water and aqueous is water solution.

It may be noted that any information which has aqua in it relates to ‘water’. Some other words are: aqua fountana, aqua regia, aquarium so on and so forth.


The root of this information is ‘arm’. Armature is any apparatus for defence. In Physics, it method a piece of iron set across the poles of a magnet, a moving part which indicates the flow of current and other uses of similar character.


Astronomy is the study of Universe beyond Earth’s air. So, the prefix ‘astro’ method something with reference to Heavenly objects like the information Astrophysics. Asteroids are small bodies that revolve around the Sun between the orbits of Mars and Jupiter. In other words, they are minor planets or off-springs in the Heaven.


The information refers to hearing sense. Auditorium is the place where we hear something. Audio-visual education is the apt replace sound and light show.


The dictionary meaning is ‘to make thin, or slender’. In Physics the information possesses the same meaning while referring to the weakening of signals.


This is an excellent English information which method ‘a hurtling mass of snow, with ice and rock, descending a mountain side’. One may be surprised to observe that this information is used with the same meaning as ‘shower’ of electrons in transistor diodes and other electronic instruments.The diode which uses this effect is known as ‘avalanche Diode’.


We have analysed some English words starting with the alphabet A used frequently in Physics along with their dictionary meanings. The roots of the words also were discussed.

The aim of this article is to create the awareness among the readers that Physics technical terms, in fact, originate from grammatical English only. Any scholar, whether those of Physics stream or Language stream should develop the habit of going thorough into the origin of the information with its meaning. If that awareness is produced, the purpose of this article is fulfilled.

The author wishes the reader all the best.
