Einstein's Theory of Relativity explained 1920's
At a certain point in his researches Professor Albert Einstein found that there were aspects of his theory of relativity which could not easily be explained by conventional methods of communication. The very nature of the relativity theory involved the concept of objects moving at different speeds, continuously observed and related to each other. Blackboard illustrations, lantern slides, diagrams, charts and large scale models all having proved either impossible or impractical m
ethods, it was suggested to Einstein that a silent motion picture might be the only system that would provide a complete illustration of the things he was trying to say.
Advice was sought from Max Fleischer, creator of "Betty Boop" and "Popeye", who collaborated with a team of Einstein's associates (Professors Nicolai, Kornblum, Bueck and others) to produce a film which sets out in simple terms the broad principles of the theory.
This film explains in very simple terms Einstein's Theory of Relativity (1905 & 1910), it also illustrates some of our past's great achievements and very briefly emphasizes the impact the theory will have on the development of new discoveries, for example electromagnetic radiation / radio waves / radar.
Two men are digging earth with spades, they throw the earth into a cart. A man turns a handle next to a door. A large mechanical spade collects earth and transfers it to a wagon. A 1910-1920 steam ship at sea. A woman gets into a 1910-1920's automobile, the automobile drives along a deserted road. A brief shot of a bridge, maybe the Hudson Bridge in New York. A steam train. 1920's New York Sky Scrapers. A pilot is flying on a 1920's aeroplane, view of the landscape below. A 1920's Radio aerial. A radio transmission or early radar developing. A woman places a man's hand on a plate on top of a table and under an X ray machine. Close up of the hand. View of a man and a woman operating the X-ray machine. Close up of the X-rayed hand, revealing the bone outline. View of a black line projected on a wall. The black line is illuminated and a close up reveals a pencil dipped in a glass full with water. The water is removed with a plastic hose and the pencil examined. A white circle against a dark background. A grey circle with a black outline against a white background. A man on a barge appears to moving forward. A man on a barge is moving along the barge. A still describing a giant rocket . A man wearing a mask and dressed like a first world war soldier. Animation showing a man walking into the giant rocket. The rocket is fired into space. Aerial view of 1920's New York Sky Scrapers. Animation describing the planet earth rotating in space. Animation showing the rocket moving in space, the rocket stops and a telescope appears on top of the rocket. The earth rotates with an arrow pointing in all directions, thus showing that direction is relative. Animation of the earth with two boats, one on the North Hemisphere and one on the South Hemisphere, both boats are raising flags. Animation describing the fall of a ball (on earth), a train wagon is moving from left to right, at the same time a ball falls from its top to the platform. Animation describing a ball falling from a tower as it would be seen from space. Animation showing how to draw ( how we would predict ) the direction of a cannon ball shot straight up from earth. Animation showing the cannon ball shot but how Einstein sees it. Animation explaining why Einstein draws the direction of the cannon ball shot straight up from the earth as a curve. Shot of a large rock or stone. The same stone is held by a hand, this illustrates that size is also relative. Animation showing the earth in relation to the moon and in relation to the sun. Animation showing that the earth in relation to the star Betelgeuse is very small. Animation showing the flight of a bullet shot from a cannon/gun. Animation illustrating the earth travelling around the sun. Animation comparing the speed of the earth around the sun in relation to the speed of a firing bullet, the bullet in comparison appears stationary. Animation showing the solar system planets travelling around the sun and their speeds in relation to one another. Animation illustrating that the speed of light is always constant: two pistols, placed opposite each other, are spinning around a wheel. While the wheel spins, the two pistols are discharged at the same instant causing two holes in a wall. The firing of the pistols is showed slowed up in order to show that the light flashes travel faster than the bullets and that the bullet fired from the top gun travel faster than the bullet fired from the bottom gun, however, both light flashes travel at the same speed. Animation showing two projectiles being fired simultaneously from the earth at the moon, both flashes of light reach the moon at the same time and before the bullets, both bullets reach the moon with different speeds, like in the spinning wheel experiment. Animation showing two towers flashing signals at the same time to a balloonist and to a man on the ground, it describes that time is not the same in different places. Animation showing that light (for example a single ray) is bent when it passes through space near a big body (for example the sun). A man is manipulating a large telescope. Animation illustrating that if we look at a star at different times, we see it in different positions. Animation showing the results of the experiments done during the 1919 eclipse, these results proved that the stars seem pushed out of place, just like Einstein predicted. Einstein added a fourth dimension: Time, it changed our perception of the universe. Animation describing time travelling, starting in 1922 a man is shot into space and travels faster and faster until he halts in 1492, that is, his former past is now his future! Blip on screen shoots out from Earth and speeds past the years in numbers which are floating in space.
