Home » Odd Stuff » Collection Of Very Rare Optical Illusion To Hypnotize You Illusions are always mind freaking.
An optical illusion (also called a visual illusion) is characterized by visually perceived images that differ from objective reality. The information gathered by the eye is processed in the brain to give a perception that does not tally with a physical measurement of the stimulus source. There are three main types: literal optical illusions that create images that are different from the objects that make them, physiological ones that are the effects on the eyes and brain of excessive stimulation of a specific type (brightness, colour, size, position, tilt, movement), and cognitive illusions, the result of unconscious inferences.
Today we have collected very rare and outstanding examples of optical illusion. Cube Shifting. Energispanarfilmen, f-6. Falken och Rosa ger en introduktion till begrepp som energi, växthusgaser och klimatförändringar.

De tidigaste organismerna var encelliga och levde för tre och en halv miljarder år sedan.
Alla organismer har genomgått en evolution och skillnaderna mellan dem beror på gradvisa anpassningar till olika livsmiljöer. Evolutionära förändringar har oftast lett till mer komplexa former men ibland har organismer förenklats, till exempel parasiter. Geologic Time: Graphical Representation of Geologic Time.

Motion makes the moon go 'round too. In fact, motion makes lots of things go. When we think of motion we often think of cars, bicycles, kids running, basketballs bouncing and airplanes flying. But motion is so much more. Motion is important to our lives and impacts so many things that we do. What is Force? Force is just a fancy word for pushing or pulling. These two forces act at a distance and do not require direct contact between the objects to function.
See D4K's site on Gravity. Magnetism produces a force that can either pull opposite ends of two magnets together or push the matching ends apart. Galileo Drops the Ball - Virtual Experiment. In around 1590 Galileo Galilei (1564-1642) climbed up the Leaning Tower of Pisa and dropped some balls to the ground.
Two balls of different masses, but of similar shape and density that were released together hit the ground at the same time. Until then it was commonly believed that heavy things fall faster than light things. Many people still believe this, and casual observation of everyday phenomena often does tend to confirm this view. If you drop a brick and a feather at the same time the brick will probably hit the ground first. But this is because of differences in the amount of friction between these objects and the air around them, not because their masses are different. Välkommen till NTA - Hem.

A: The simple answer is something less than half full. Since the compressed air stores the energy, and the water provides momentum, both are needed. Fill perhaps 40-50% of the motor volume with water. We call this the Load Fraction. The longer answer is, it depends. The following factors effect how much water is optimal: Empty weight of the rocket, cross-sectional area (or diameter) of the rocket, nozzle diameter, operating pressure, and drag coefficient.

By Anna Gunnarsson What makes a good Berta activity? All the Berta activities have been tried out with young children many times over several years to ensure that they are interesting and easy to do. When we choose activities for Berta and her young experimenter friends, we always look for these key elements: - Safety: can the children safely experiment with the ingredients, even if some of them happen to end up in their mouths (it doesn’t matter if they taste bad – but they have to be edible to find this out)? - Child appeal: are the results fun, clear enough to see or touch, and a bit unexpected or even amazing? - Exploration: does the chemistry raise interesting questions, and will it lead to new experiments and experiences? In this article we describe three popular activities that are typical of Berta’s style. About what happens.
