The purpose of primary reading is to understand the main content of the text, which develops some skills of a purposeful intelligent reading.
It is not recommended to translate the text in details as sometimes it is not considered as one of the effective ways of working at the text. The work before reading the text and translation of some sentences considerably facilitate the process of mastering the language material.
Control and choice of texts for independent work are carried out at a teacher’s discretion.
At the final stage of work it is possible to speak on the topic chosen by learners or a teacher.

Scientific Notation
Although physics and mathematics aren't the same thing, they are in many ways closely related. Just like English is the language of this content, mathematics is the language of physics. A solid understanding of a few simple math concepts will allow us to communicate and describe the physical world both efficiently and accurately.
Because measurements of the physical world vary so tremendously in size (imagine trying to describe the distance across the United States in units of hair thicknesses), physicists often times use what is known as scientific notation to denote very large and very small numbers. These very large and very small numbers would become quite cumbersome to write out repeatedly. Imagine writing 4,000,000,000,000 over and over again. Your hand would get tired and your pen would rapidly run out of ink! Instead, it's much easier to write this number as 4×1012. See how much easier that is? Or on the smaller scale, the thickness of the insulating layer (known as a gate dielectric) in the integrated circuits that power our computers and other electronics can be less than 0.000000001 m. It's easy
