Since it is the seller’s weights that are regularly used during transactions, storing his weights in salt could lead to the customers receiving less than the amount agreed upon

For example, if you place a book on a table and give it a push, it will move a bit then stop. The kinetic friction absorbs the energy you transfer to the book in the push. Static friction, on the other hand, occurs when an object is stationary; it’s what prevents it from moving.

Light is a funny thing. Its wavelength defines what it can and can’t interact with. Anything smaller than the wavelength is functionally nonexistent to that photon. That’s why there’s a mesh over the window of a microwave. The holes in the mesh are too small for microwaves to pass through. But visible light, with a much shorter wavelength, can go t

image. In this way, the pornographic image attempts to be both more and less than an image: seeking to substitute itself for the prototype (more) and closing itself off from transformation beyond itself (less). Like most illusions, the pornographic image is both more and less real than it should be.

Starlight and sunlight, split by a diffraction grating, display their own distinctive patterns of colour. I have always wanted to see this for myself, and recently bought an old spectrograph. It resembles two miniature telescopes mounted on a dais marked with numbers, and has been testing my poor skills and my patience for weeks. Then yesterday, ju
