Imagine a scientist who has teleported to space. His spacesuit’s pressurized air protects his bodily fluids from vaporization, its oxygen tank keeps him breathing, and the insulation prevents him from freezing. But although these features thwart an immediate tragedy, space is still an incredibly dangerous place. So, what does a prolonged stay in space do to the human body? Tejal Gala investigates.

Lesson by Tejal Gala, directed by Henrique Barone.

Examine how popular personality tests, like the Myers-Briggs Type Indicator and the Enneagram, are designed and their inconsistencies.

Uploaded 22-12-20

--

In 1942, a mother-daughter duo named Katherine Cook Briggs and Isabel Briggs Myers developed a questionnaire that classified people’s personalities into 16 types. Called the Myers-Briggs Type Indicator, or MBTI, it would go on to become one of the world’s most widely-used personality tests. But do these tests actually reveal truths about personality? Merve Emre examines their design flaws.

Lesson by Merve Emre, directed by Seoro Oh.

Spartacus was enslaved — one of millions taken from territories conquered by Rome to work the mines, till the fields or fight for a crowd’s entertainment. Imprisoned for deserting the Roman Army, he and other enslaved people fought their way free and started a rebellion. How did an enslaved man become synonymous with freedom and courage? Fiona Radford delves into the life and legend of Spartacus.

Uploaded 30-09-21

--

Over 2,500 years ago, one of ancient Greece’s most celebrated popstars and erotic poets enraptured listeners. The singer-songwriter offered a uniquely intimate perspective on love, passion, and longing, and was the first on record to combine the words “bitter” and “sweet,” to describe the ups and downs of romance. So, who was this revered figure? Diane J. Rayor uncovers the writings of Sappho.

The dwarves were master craftspeople. One dwarf, Andvari, forged marvelous creations. He often took the form of a fish and, one day, he swam to the land of the water nymphs, who guarded mounds of gold. When the nymphs laughed at his appearance, Andvari grew infuriated and seized their gold. With it, he crafted himself a special ring. Iseult Gillespie shares the Norse myth of the cursed ring.
