Curiosity, answered properly.

The internet is full of quick answers, but not all of them are accurate, complete or easy to follow. se7enW exists to give every question a clear short answer, a fuller explanation with real figures, and a handful of memorable facts — so readers come away understanding the topic, not just the headline.

Our library is organised into seven sections, each dedicated to one kind of question:

• Why — Uncover the reasons behind everyday wonders and cosmic mysteries.
• What — Define, measure, and understand the things that shape our world.
• When — Journey through the timelines of history-defining events.
• Where — Explore the remarkable places and locations across our planet.
• Which — Compare, rank, and discover the superlatives of nature and humanity.
• Whose — Meet the people and stories behind the greatest achievements.
• HoW — Understand the mechanisms, numbers, and processes that run the universe.

Topics span science, history, nature, geography, space, technology, culture and sport. Every entry includes a short answer, a detailed explanation, key facts, and “Did you know?” extras.

• Accuracy first. Figures and dates are checked against reputable references such as encyclopaedias, scientific bodies and official records.
• Clarity over jargon. Explanations are written for students, teachers, families and lifelong learners.
• Continuous improvement. Knowledge evolves, and we update entries when better information becomes available.

se7enW is made for curious minds of all ages — students revising for exams, educators planning lessons, quiz lovers, and content creators looking for fascinating, well-researched topics.
