The Theory of Relativity Part 5 (May 3, 2010)
Description
The lecturer explains Albert Einstein's equivalence principle, demonstrating how acceleration affects a beam of light projected inside an elevator in space. From this, he derives the conclusion that gravity causes the path of light to bend. This leads to the fundamental understanding that spacetime itself is an entity that curves in the presence of mass.
Original title
תורת היחסות - חלק 5 (3.5.2010)
המרצה מסביר את עקרון השקילות של אלברט איינשטיין ומדגים כיצד תאוצה משפיעה על קרן אור המוקרנת בתוך מעלית בחלל. מתוך כך נגזרת המסקנה כי כבידה גורמת לעיקום מסלול האור, מה שמוביל להבנה שמרחב-זמן עצמו הוא ישות שמתעקמת בנוכחות מסה.

Daniel Asks: Why Are We Afraid of the Dark
Credit: מכון דוידסון לחינוך מדעיThe fear of the dark is an ancient evolutionary survival mechanism designed to protect us from predators lurking in places we cannot see. Our brains tend to fill in missing visual information with our imagination, which triggers a sense of danger and anxiety in children and adults alike. Understanding the evolutionary roots of this fear helps us confront it in a more rational and calming manner.2:48

Why Is the Ocean Salty?
Credit: מכון דוידסון לחינוך מדעיThe salinity of the oceans stems primarily from the erosion of rocks on land by slightly acidic rain, which dissolves minerals and carries them through rivers into the sea. As water evaporates from the ocean surface, these salts are left behind, their concentration steadily increasing over billions of years. Additional sources of salt include hydrothermal vents on the seafloor and underwater volcanic activity.2:33
