Context: This is not the first time that our people have had to deal with an attack of an arrogant foe. At the time of Napoleon’s invasion of Russia our people’s reply was war for the fatherland, and Napoleon suffered defeat and met his doom.
It will be the same with Hitler, who in his arrogance has proclaimed a new crusade against our country. The Red Army and our whole people will again wage victorious war for the fatherland, for our country, for honor, for liberty.
The government of the Soviet Union expresses the firm conviction that the whole population of our country, all workers, peasants and intellectuals, men and women, will conscientiously perform their duties and do their work. Our entire people must now stand solid and united as never before.
Each one of us must demand of himself and of others discipline, organization and self-denial worthy of real Soviet patriots, in order to provide for all the needs of the Red Army, Navy and Air Force, to insure victory over the enemy.
The government calls upon you, citizens of the Soviet Union, to rally still more closely around our glorious Bolshevist party, around our Soviet Government, around our great leader and comrade, Stalin. Ours is a righteous cause. The enemy shall be defeated. Victory will be ours.

Context: What is mass? According to Newton, it is the product of the volume by the density. According to Thomson and Tait, it would be better to say that density is the quotient of the mass by the volume. What is force? It, is replies Lagrange, that which moves or tends to move a body. It is, Kirchhoff will say, the product of the mass by the acceleration. But then, why not say the mass is the quotient of the force by the acceleration?
These difficulties are inextricable.
When we say force is the cause of motion, we talk metaphysics, and this definition, if one were content with it, would be absolutely sterile. For a definition to be of any use, it must teach us to measure force; moreover that suffices; it is not at all necessary that it teach us what force is in itself, nor whether it is the cause or the effect of motion.
We must therefore first define the equality of two forces. When shall we say two forces are equal? It is, we are told, when, applied to the same mass, they impress upon it the same acceleration, or when, opposed directly one to the other, they produce equilibrium. This definition is only a sham. A force applied to a body can not be uncoupled to hook it up to another body, as one uncouples a locomotive to attach it to another train. It is therefore impossible to know what acceleration such a force, applied to such a body, would impress upon such an other body, if it were applied to it. It is impossible to know how two forces which are not directly opposed would act, if they were directly opposed.
We are... obliged in the definition of the equality of the two forces to bring in the principle of the equality of action and reaction; on this account, this principle must no longer be regarded as an experimental law, but as a definition.<!--pp.73-74
