Opportunity had far outli

vt.physics on Instagram: "This Water Trick Will Blow Your Mind! The Worthington jet effect happens when an object hits a liquid surface, forming a cavity that quickly collapses due to pressure and surface tension. As the liquid rushes back inward, the energy focuses at the center and shoots upward, creating a thin, high-speed jet of liquid. This process demonstrates how impact energy is redirected into a vertical motion and is influenced by factors such as impact speed, liquid viscosity, and sur

Explaining The Universe on Instagram: "Pi (π) is a mathematical constant that represents the ratio of a circle’s circumference to its diameter. It is an irrational number, meaning its decimal expansion never ends or repeats, and its approximate value is 3.14159. Pi is one of the most important numbers in mathematics and science, appearing in countless formulas related to geometry, physics, and engineering. It is used to calculate the area and circumference of circles, the surface area and volume
