In this sleepy episode, I tell you about the long history of timekeeping devices, from the first sundials and water clocks to mechanical clocks, quartz timers, and atomic clocks. Beyond technique, we also explore how the perception and management of time are cultural phenomena.

This bedtime story tells you the Epic of Gilgamesh based on the Standard Babylonian Version. I also tell you about Mesopotamian mythology and the emergence of civilizations in the region, from Sumer and Akkad to Assyria and Babylonia.

Tonight, I tell you the sleepy stories of four different ghost ships, together with their historical context and what happened to them. Two are fictional: the Flying Dutchman, a flute from the Age of Sails that would have traded between Amsterdam and the Spice Islands, and the Caleuche, a legendary ship on the island of Chiloe, Chile. Two are real: the Mary Celeste that mysteriously lost her crew in the Atlantic Ocean, and the Baychimo, which was abandoned but unexpectedly kept wandering for decades in the waters north of Canada and Alaska.

In this bedtime story, I take you on an underwater cruise to the various layers of the Earth's oceans. I talk about marine life, its evolution, and the conditions it had to adapt to. Types of animals or species we look at in more detail include jellyfish, coral, sharks, giant squids, sperm whales, the components of plankton, fishes from the bathyal zone and below, or the inhabitants of ecosystems around cold seeps and hydrothermal vents. We also make a bit of time travel, and I tell you about some of the largest creatures that dominated our seas from the Cambrian period to today: trilobites, anomalocaris, sea scorpions, placoderm fishes, plesiosaurs, ichthyosaurs, mosasaurs or megalodons.

This bedtime story is about One Thousand and One Nights (also known as "Arabian Nights"). I tell you several famous stories from this compilation of Middle Eastern and North African folk tales and legends. These include the framing story with Scheherazade and Shahryar, "Ali Baba and the Forty Thieves," "The Merchant and the Genie," "Sinbad the Sailor" and his seven voyages, and "Aladdin and the Magic Lamp." I also tell you a little bit about where this compilation of stories comes from.

Tonight, I tell you three different stories:

- Area 51: How did this USAF base gain its reputation for being at the center of numerous conspiracies, including the dissimulation and reverse-engineering of alien technology? We take a look at what is documented, from its creation in 1955 as a test facility for the Lockheed U-2 reconnaissance aircraft, to the study of foreign technology and the intense secrecy around the base's activities.
- Chaco Canyon is a large archaeological site in New Mexico, built more than a thousand years ago and over several generations by the Ancestral Puebloans. But it was obviously not just a residence settlement: What is the meaning, and the function of these alignments based on astronomical observation and cardinal directions, the care given to landscaping, or this enigmatic web of roads that radiate from the canyon?
- The Toba Catastrophe Theory hypothesizes that a supervolcano that erupted around 70,000 years ago in Indonesia would have dramatically affected the course of life on Earth, including mankind. What are supervolcanoes? What is it based on? What could have happened?

This is a soft-spoken science bedtime story about Earth: its formation, its structure, and how mankind perceived the World before its exploration and the space age. In this video, I tell you about what we know or suppose of Earth's formation in the solar system, its geology, its internal structure from the crust to the core, and how all these interact. We discuss plate tectonics and continental drift, the chemical elements our planet is made of, its temperature, its future in several billion years, its magnetic field and how it could be generated by its metallic core, and many more things.

In these three new historical mysteries, I tell you about the Pythia, the High Priestess of Apollo in Delphi, who for more than a millennium delivered sought-after prophecies in a state of frenzy - but the Oracle may have been more ancient than Classical Greece. The second story is about the myth of changelings, that is to say newborns, or young children that would have been exchanged by fairies, or trolls in the Scandinavian version. Why this belief, and how did it appear? I also added a touch of true crime with the story of Bridget Cleary, a woman murdered in 1895 because she was believed to be a changeling. The third story takes us from Russia and Germany to the USA in the 20th Century: who were all these women claiming to be Grand Duchess Anastasia, the youngest daughter of the last Tsar of Russia, miraculously alive? This modern mystery found an answer thanks to DNA, I tell you how, and a little bit about Eugenia Smith or Anna Anderson.
