1,963 AD

Martin Luther King Jr. delivers his “I Have a Dream” speech in Washington, D.C.

A mass demonstration placed civil rights at the center of national attention.

More than 200,000 people gathered for the March on Washington for Jobs and Freedom. King’s address at the Lincoln Memorial became an enduring statement of the movement’s demand for equality and helped build support for federal civil rights legislation.

1,948 AD

The United Nations General Assembly adopts the Universal Declaration of Human Rights.

The declaration set a shared standard without becoming a treaty itself.

Drafted by an international committee and adopted in Paris, the declaration articulated civil, political, economic, social, and cultural rights. It influenced later constitutions and international human-rights agreements.

1,990 AD

The Hubble Space Telescope is deployed into low Earth orbit.

A flawed mirror was repaired, and the observatory became a scientific icon.

Hubble initially produced blurred images because of a tiny error in its primary mirror. Astronauts installed corrective optics during a servicing mission, enabling decades of discoveries about stars, galaxies, and the expansion of the universe.

221 BC

The king of Qin defeats the last rival state and claims a new imperial title.

Short-lived Qin rule established a durable model of centralized empire.

Qin Shi Huang standardized measures, writing practices, and administration across conquered states. The dynasty fell soon after his death, but the imperial framework influenced Chinese government for more than two millennia.

100 BC

Greek craftspeople build the geared device now called the Antikythera mechanism.

Bronze gears modeled cycles of the sky with astonishing mechanical sophistication.

Recovered from a shipwreck, the mechanism used interlocking gears to track astronomical cycles and calendar displays. Imaging and reconstruction have revealed a level of ancient precision once thought much later.
