Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works extremely well in its own domain: Quantum theory explains how atoms and ...

Physical-collapse theories have long offered a natural solution to the central mystery of the quantum world. But a series of increasingly precise experiments are making them untenable. How does ...

To the best of our knowledge, we humans can only experience this world in three spatial dimensions (plus one time dimension): up and down, left and right, and forward and backward. But in two physics ...

No anniversary list is ever complete. Just last month, for instance, my Top 10 scientific anniversaries of 2018 omitted the publication two centuries ago of Mary Shelley’s Frankenstein. It should have ...

Machines that learn like babies: Reinforcement learning expert David Silver speaking at the Heidelberg Laureate Forum on 15 September, 2025. (Courtesy: Bernhard Kreutzer/HLF) Today’s artificial ...

Curiosity comes naturally to children. From an early age they are asking questions and conducting science experiments (even if they don't know it!). "What happens if I throw this ball?" "How can I go ...

The world looks so different after learning science. For example, trees are made of air, primarily. When they are burned, they go back to air, and in the flaming heat is released the flaming heat of ...

Are you looking for engaging and educational activities to spark your child’s curiosity? A great solution is to set up easy science experiments that use everyday household items and bring science to ...
