However completely people might fulfil themselves in other spheres, if they don’t possess this understanding between their hands and material objects, they can never have more than an incomplete understanding of the world.

Truth to tell, it was a bit difficult for him at first to get used to such limitations, but later it somehow became a habit and went better; he even accustomed himself to going entirely without food in the evenings; but instead he was nourished spiritually, bearing in his thoughts the eternal idea of the future overcoat. From then on it was as if his very existence became somehow fuller, as if he were married, as if some other person were there with him, as if he were not alone but some pleasant life's companion had agreed to walk down the path of life with him––and this companion was none other than that same overcoat with its cotton-wool quilting, with its sturdy lining that knew no wear.

I really enjoy when I'm asked questions that leap from the physical world and the material world into our hearts.

Children need to be exploring their physical world. They need to be learning the fundamental laws of physics by manipulating objects.

Every element of understanding of the physical world has flexibility.

As two massive objects pass near each other, gravitational forces induce dramatic physical changes -- decompressing, melting, stripping material away and even annihilating the smaller object.
