Giving money to someone like Maxwell might have seemed the most absurd encouragement of mere "curiosity-driven" science, and an imprudent judgment for practical legislators.  Why grant money now, so nerdish scientists talking incomprehensible gibberish can indulge their hobbies, when there are urgent unmet national needs? Maxwell wasn't thinking of radio, radar, and television when he first scratched out the fundamental equations of electromagnetism; Newton wasn't dreaming of space flight or communications satellites when he first understood the motion of the Moon; Roentgen wasn't contemplating medical diagnosis when he investigated a penetrating radiation so mysterious he called it "X-rays"; Curie wasn't thinking of cancer therapy when she painstakingly extracted minute amounts of radium from tons of pitchblende; Fleming wasn't planning on saving the lives of millions with antibiotics when he noticed a circle free of bacteria around a growth of ...

Logic Gates Explained: Symbols, Boolean Expressions & Truth Tables Logic gates are the foundation of digital electronics and computer logic. This chart neatly compares all major logic gates—AND, OR, XOR, NOT, NAND, NOR, and XNOR—using symbols, Boolean expressions, Venn diagrams, and truth tables. It helps students clearly understand how inputs A and B combine to produce an output. Perfect for exam revision, quick recall, and building strong fundamentals in Boolean algebra and digital logic systems.

One idea can quietly reshape everything we think we know. Some interpretations of quantum physics suggest that death may not be a final ending, but a shift in perspective—an apparent boundary rather than an absolute stop. From this view, consciousness does not simply vanish when the body fails. At the quantum level, reality behaves in ways that challenge everyday logic. Particles exist in multiple states, time behaves strangely, and observation itself appears to influence outcomes. These principles open space for questions science has not fully answered. Rather than offering certainty, this perspective invites humility. It reminds us that human understanding remains incomplete, especially when it comes to existence, awareness, and continuity. If death is not a wall but a doorway we do not yet comprehend, then fear loses some of its grip. The idea encourages reflection on how we live now—how presence, compassion, and meaning may matter more than final outcomes. 

Newton wrote more about theology than about science and math combined. He was deeply religious and spent a considerable amount of time studying the Bible, writing about his interpretations of scripture, and predicting the end of the world, which he speculated would not occur before 2060.

Research shows creativity boosts happiness, slows ageing, and even lowers disease risk. Engaging in creative arts is emerging as a powerful, evidence-based strategy for improving both mental and physical health across the lifespan.  Drawing on large cohort studies, Daisy Fancourt shows that people who frequently participate in activities such as music, dance, crafting, theatre, reading, and writing report greater happiness and life satisfaction, and have lower risks of depression, loneliness, antisocial behaviors, and even some physical conditions as they age. Arts engagement in childhood is linked with better prosocial skills and fewer behavioral problems in adolescence, while older adults who maintain hobbies and attend cultural events show better self-rated health, sleep, cognition, balance, less frailty, and even reduced risks of diseases like diabetes. Biological data suggest that regular artistic activity is associated with lower blood pressure, healthier immune a...
