The objective of table tennis, also known as ping pong, is to score points by hitting a lightweight ball over a net and into the opponent's side of a rectangular table. Players use paddles to strike the ball, aiming to make it bounce on the opponent's side in a way that makes it difficult for them to return.

A game typically consists of either 11 or 21 points, and a player must win by at least a two-point margin. Players alternate serves, and each player has the opportunity to score points when the opponent fails to return the ball correctly.

The sport emphasizes quick reflexes, strategic placement, and spin techniques, making it both physically demanding and mentally engaging. Matches can be played in singles (one-on-one) or doubles (two-on-two) formats.

Ultimately, the goal is to outmaneuver the opponent, capitalize on their mistakes, and consistently place the ball in areas that are challenging to defend. Winning a match requires skill, practice, and a deep understanding of the game's tactics.

Stocks and bonds are two fundamental types of investment instruments, but they serve different purposes and come with distinct characteristics.

Stocks represent ownership in a company. When you buy a stock, you purchase a share of that company, which means you have a claim on its assets and earnings. Stocks can provide returns through capital appreciation (if the stock price increases) and dividends (a portion of the company's profits distributed to shareholders). However, they come with higher risk, as stock prices can be volatile and are influenced by market conditions and company performance.

Bonds, on the other hand, are debt instruments. When you buy a bond, you are essentially lending money to the issuer (which could be a corporation or government) in exchange for periodic interest payments and the return of the bond's face value at maturity. Bonds are generally considered safer than stocks, as they provide fixed income and have a priority claim over stocks in the event of bankruptcy. However, they typically offer lower potential returns compared to stocks.

In summary, stocks offer ownership and potential for higher returns with higher risk, while bonds provide fixed income and lower risk.

The pyramids of Egypt, particularly the famous ones at Giza, served primarily as monumental tombs for pharaohs and high-ranking officials. Built during the Old and Middle Kingdom periods, these structures were designed to honor and protect the deceased in the afterlife. The ancient Egyptians believed in an afterlife where the soul would continue to exist, and the pyramids were constructed to ensure a safe passage and provide for the needs of the deceased.

The pyramids also symbolized the pharaoh's power and divine status. Their massive scale and intricate design reflected the civilization's architectural prowess and served as a testament to the pharaoh's ability to mobilize resources and labor. Additionally, the pyramids were often part of larger mortuary complexes that included temples and smaller tombs, emphasizing the importance of religion and the afterlife in Egyptian culture.

Overall, the pyramids were not just tombs; they were a blend of religious, political, and cultural significance, embodying the ancient Egyptians' beliefs about life, death, and the cosmos.

The Theory of Relativity, developed by Albert Einstein in the early 20th century, fundamentally changed our understanding of space, time, and gravity. It consists of two parts: Special Relativity and General Relativity.

Special Relativity, introduced in 1905, posits that the laws of physics are the same for all observers, regardless of their relative motion. It introduces the concept that the speed of light is constant in a vacuum for all observers, leading to the famous equation E=mc², which shows the equivalence of mass and energy.

General Relativity, published in 1915, expands on this by describing gravity not as a force but as a curvature of spacetime caused by mass. Massive objects like planets and stars warp the fabric of spacetime, influencing the motion of other objects. This theory has profound implications, explaining phenomena such as the bending of light around massive bodies and the expansion of the universe.

Overall, the Theory of Relativity reshapes our understanding of the universe, illustrating that space and time are interconnected and that gravity is a geometric property of spacetime.
