There are only questions and questions, if some one knows the answers...please feel free to share!
ENERGY
• What is it that keeps the Earth floating in space? • Why does a top stand upright when it is spun from the side? • What is temperature? What is heat? What is cold? • What is energy? • What is evaporation? • What is vaporization? • What is dissolution? • What is combination? • What is absorption? • On what effects are these processes founded?
MAGNETISM
• Why do the magnetic lines of force run from south to north? • Why does the Earth rotate from west to east? • Why do the magnetic lines create vortex as it goes around
THE SUN
• What serves the sun as a carrier of light and heat, if, in the view of our learned scientists, space is a vacuum? • Why do gases condense with a decrease in temperature? • Why don't the fiery gases of the Sun, with supposed temperatures of over 6000o C, stream out into space? • Why is the light and heat in the tropics more diffuse and at the poles the Sun's light more intense and its radiant heat less?
ATMOSPHERE
• Why doesn't the Earth's warm air rise? • Why is it so cold at the top of a mountain, i.e. nearer the Sun? • Why in our houses is it warmer nearer the ceiling and colder at the floor, when an artificial source of heat is used? • Why does marble expand with heat and why doesn't it contract again with cold? EVAPORATION • Why is the desert so dead despite all the heat? • Why do damp tiled roofs dry out from the eaves towards the ridge?
WATER
• Why does the groundwater in walls rise far above the surface of the ground? • Why don't wooden posts rot under water, but above it always? • Why can rising cold water pierce through the hardest rock? • Why does water pulsate and breathe? • Why does groundwater manage to remain on the sides of mountains? • Why, growing colder and heavier, does it rise upwards? • Why does it frequently spring from high peaks?
RIVERS
• Why do west-to-east flowing watercourses fertilise their banks? • Why are the banks of east-to-west flowing rivers so barren? • Why are the banks of south-to-north flowing watercourses fertile on one side only? • Why do rivers flowing into cold seas migrate laterally to the north? • Why do deltas and estuaries develop? • Why does a trout stand still in a raging torrent, as if by magic?
THE SEA
• Why is the water at the poles warmer at the bottom? • Why is the sunlit surface at the poles so icily cold? • Why doesn't the warmer, lighter bottom-water of the sea rise upwards? • Why are the water temperatures at the equator so warm? • Why is it that it gets colder with increasing depth? • Why does it get warmer again below the boundary layer of +4o C? • Why does life below this boundary layer begin anew? • Why does the salt content of the seas vary? • Why do herrings migrate northwards in winter? • Why do deep-sea fish glow? • Why can the warm Gulf Stream push the cold seawater aside and wend its way for thousands of kilometers over mountains and valleys in a reversed temperature gradient without the assistance of a mechanical gradient?
BLOOD
• Why do cold-blooded animals carry fever-inducing poison? • Why does a cold fever occur in the tropics? • Why does a warm fever arise from a chill? • What is fever anyway? • Why is our body temperature subnormal when climbing a mountain and above normal as we descend? • Why does the heart beat in our breast? • Who gives this muscle its impulse to move? • Where is the motor for this pump? • Why does blood circulate in our blood vessels? • Why do the fluids in a chicken's egg circulate without a heart? • Why do we breathe day and night, when asleep and even when totally unconscious? • Does the heart beat because we breathe, or do we breathe because the heart beats? TREES • Why have light-demanding timbers a thick bark and shade-demanders only a thin one? • Where is the heart of a plant? [from Our Senseless Toil
