What is photosynthesis?

Photosynthesis is the biochemical process through which plants convert light energy into chemical energy. This process uses carbon dioxide and water to produce glucose and oxygen, forming the foundation of most food chains.

What is the Pythagorean theorem?

The Pythagorean theorem states that in a right triangle, the square of the hypotenuse equals the sum of squares of the other two sides (a² + b² = c²). This fundamental principle has applications across mathematics, physics, engineering, and architecture.

Who wrote 'Pride and Prejudice'?

Jane Austen wrote 'Pride and Prejudice', publishing it anonymously in 1813. The novel follows Elizabeth Bennet as she navigates issues of manners, upbringing, and marriage in early 19th-century England.

What is Newton's First Law of Motion?

Newton's First Law states that an object at rest will remain at rest, and an object in motion will remain in motion unless acted upon by an external force. This principle forms a cornerstone of classical mechanics and explains why objects move or remain stationary.

What is the capital of Japan?

Tokyo is the capital and largest city of Japan, serving as the country's political, economic, and cultural center. Originally a small fishing village named Edo, it became the imperial capital in 1868 and is now the most populous metropolitan area in the world.

What does HTML stand for?

HTML stands for HyperText Markup Language, the standard markup language used to create web pages. It uses a system of tags and attributes to define the structure and content of web documents, working alongside CSS and JavaScript to create interactive web experiences.

When did World War II end?

World War II ended in 1945, with the European theatre concluding on May 8 (V-E Day) and the Pacific theatre on September 2 (V-J Day). The war involved over 30 countries, claimed 70-85 million lives, and reshaped global political alignments for decades.

What is the chemical formula for water?

The chemical formula for water is H₂O, indicating that each molecule consists of two hydrogen atoms bonded to one oxygen atom. Its bent shape and hydrogen bonding capabilities explain water's unique properties and its critical importance to all known forms of life.

What is the largest planet in our solar system?

Jupiter is the largest planet in our solar system, with a mass 2.5 times that of all other planets combined. This gas giant has a diameter more than 11 times that of Earth and is notable for its Great Red Spot and system of at least 79 moons.

What is mitosis?

Mitosis is the process of cell division that results in two identical daughter cells, each with the same number of chromosomes as the parent cell. The process occurs in several phases and is essential for growth, development, and tissue repair in multicellular organisms.

Spaced repetition

Spaced repetition is a science-backed learning technique that involves reviewing information at increasing intervals to improve retention.

Practice with an AI tutor

Owl includes an AI tutor that can guide you through your studies, answer questions, and help you stay on track. You can still study normally, if you like plain old flashcard review. No pressure.

Smart study reminders

Owl will remind you when to review your studies, so you can focus on what's important. We won't email you unless it matters.

Progress tracking

Owl will track your progress, so you can see how you're doing. It will show you statistics on your performance with individual decks, individual cards, and overall.

We built Owl for our own use, and now we're sharing it with you. Happy learning! 🧠
