The popular image of Vikings with horns on their helmets is a historical myth created by artists and costume designers long after the Viking Age.

Historical Myth:

• 🎨 Opera Origin: The myth began in the 1870s when costume designer Carl Emil Doepler added horns to helmets for Wagner's opera cycle.
• 🛡️ Practicality: In real battle, horned helmets would have been impractical as they could easily be caught on weapons or knocked off.

Archaeological Proof:

• 🔍 No Evidence: Out of all the Viking helmets ever discovered, not a single one has been found to have horns.

The 'Google Effect' (Digital Amnesia) is a psychological trend where our brains forget information that is easily accessible via search engines.

Storage Strategy:

• 💾 External Memory: Instead of remembering the fact itself, the brain prioritizes remembering where to find the information (e.g., a specific website).
• ⚡ Efficiency: This is a form of cognitive offloading, where the brain saves energy by relying on external digital storage.

Impact on Learning:

• 🎓 Deep Processing: Studies suggest that relying on search may lead to shallower understanding compared to memorizing and internalizing data.
