PSLE Science Reality Lab Vol No.585 | Spectral Resolution = 10 nm — Can the Satellite See Ground Details 10 nm Apart?
Learn why spectral resolution describes wavelength detail, not ground detail, and how to separate spectral, spatial, temporal and radiometric resolution.
-
PSLE Science Reality Lab Vol No.584 | Daily Mean Streamflow = 100 m³/s — Was the River Flowing at 100 m³/s All Day?
Learn why daily mean streamflow summarizes changing river flow over 24 hours, not a constant all-day value, using PSLE Science evidence reasoning.
-
PSLE Science Reality Lab Vol No.583 | Storm Tide = 3 m — Did the Storm Surge Alone Raise the Sea by 3 m?
Learn why storm tide combines astronomical tide and storm surge, and how PSLE Science evidence reasoning prevents coastal water-level claims from being mixed up.
-
PSLE Science Reality Lab Vol No.582 | “Young’s Modulus = 200 GPa” — Does That Mean the Material Is Stronger and Can Carry More Load?
Learn why Young’s modulus measures elastic stiffness, not strength or load capacity, and how PSLE Science evidence reasoning tests material claims.
