How Do Sunflowers Face The Sun?
Young sunflowers face the sun when it rises in the east and then track its motion in the sky throughout the day till it sets in the west in the evening. The process repeats the next day, as sunflowers return to their ‘starting’ position,...

Why Venus and Uranus Rotate Differently Than Other Planets?
The rotation of the planet around its axis can be generally of two types: prograde and retrograde. Prograde rotation indicates that the motion is in the same direction as the Suns rotationwhich is counter-clockwiseif youre looking down...

Why Do Wheels Appear to Spin Backwards (at High Speeds)?
At high speeds, wheels may appear to be turning backwards, creating an optical illusion known as the Wagon wheel effect. This happens because our brains fill in gaps between images to create the illusion of continuous movement. As a...
