Behold the perfect fusion of physics and mental health! In navigation, the "angle of depression" is the downward angle from horizontal when viewing something below you. But here, it's brilliantly repurposed as the existential outlook of a scientist/student staring into the abyss of... well, everything. That downward-sloping line isn't just measuring elevation—it's measuring life satisfaction! This is what happens when you understand enough physics to measure precisely how bleak things are. Next time someone asks about your worldview, just whip out a protractor and say "approximately 45 degrees below horizontal."
