What Is The 4th Dimension?
Physicist Brian Greene explains how the fourth dimension might exist beyond our direct experience. Using a garden hose analogy, he suggests that just as tiny curled-up dimensions could exist in space, our reality may have hidden dimensions we can’t perceive. The concept stems from string theory and Einstein’s ideas about space-time, though no physical proof exists yet. These dimensions might be too small for current technology to detect.
What Is The "e" Number On My Calculator?
Euler’s number (e), approximately 2.718, is a fundamental mathematical constant that appears in many real-world applications. It was first discovered through studies of compound interest and later found in probability, statistics, physics, and engineering. The number e plays a crucial role in exponential growth, decay processes, and even random probability problems. Its unique properties make it essential in fields ranging from finance to thermodynamics.
Why Is Bill Gates Buying Farmland?
Bill Gates has become the largest private farmland owner in the U.S., owning about 270,000 acres across 18 states. His investment group purchases farmland for its stability and long-term value, not necessarily for environmental reasons. While Gates allows farmers to continue operating the land, some experts worry that billionaires buying farmland could make it harder for younger farmers to afford land. However, Gates has also mentioned sustainability initiatives, such as improving seed productivity.
