Light always travels at a speed of 299,792,458 meters per second. But if you're in motion too, you're going to perceive it as traveling even faster -- which isn't possible! In this second installment of a three-part series on space-time, CERN scientists Andrew Pontzen and Tom Whyntie use a space-time diagram to analyze the sometimes confounding motion of light.

Trace the history and evolution of the Spanish language, from its origins in the 3rd century BCE to modern day.

--

Beginning in the third century BCE, the Romans conquered the Iberian peninsula. This period gave rise to several regional languages in the area that’s now Spain, including Castilian, Catalan, and Galician. One of these would become Spanish— but not for another 1,500 years. Those years tell the origin story of what’s become a global modern language. Ilan Stavans traces the evolution of Spanish.

Lesson by Ilan Stavans, directed by Hernando Bahamon, Globizco Studios.

Discover the scientific process art conservators use to restore centuries-old paintings and fix the damage of past restorations.

--

Prior to the mid-20th century, art restorers took a heavy-handed approach, often drastically altering paintings in the name of “improving” art. Today, they focus on keeping the original work intact with minimal intervention, and must regularly contend with past modifications. So, how is damaged artwork repaired? Noah Charney explains the painstaking process of restoring priceless artifacts.

Lesson by Noah Charney, directed by Michael Kalopaidis, Zedem Media.
