מסע אל הקרינה האלקטרומגנטית: קרינה אינפרא אדומה
קרינת התת-אדום (אינפרא אדום) היא מרכיב בלתי נראה בספקטרום האלקטרומגנטי שמקיף אותנו כל העת. גלו כיצד אנו חשים בה כחום, אילו שימושים טכנולוגיים קיימים עבורה — משלטים רחוקים ועד ראיית לילה — ואיך המדע רותם אותה לחקר היקום והגופים הפולטים אותה.

Daniel Asks: Why Are We Afraid of the Dark
The 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?
The 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
