Science is the systematic pursuit of knowledge about the natural world, and its discoveries have reshaped human civilization more profoundly than any other force in history. From the quantum realm where particles exist in multiple states simultaneously to the vast scales of cosmology where galaxies drift through the void, science reveals a universe stranger and more wonderful than anything our ancestors could have imagined.
The periodic table organizes all known types of matter based on atomic structure. When Dmitri Mendeleev published his periodic table in 1869, he left gaps for undiscovered elements and correctly predicted their properties. Today the table contains 118 confirmed elements, with the heaviest existing only fleetingly in particle accelerators.
