Eigenvalues and a Long Run
Morning
Started on eigenvalues today. The concept makes sense intuitively (stretching vectors), but the actual computation with complex numbers is tricky. Watched a 3Blue1Brown video that helped a lot.
Afternoon
Needed a break from math so went for a run. Did 5K in 24:30 — not a PB but felt good. The trail by the river is beautiful this time of year.
Evening
Came back to eigenvalues with fresh eyes. Made more progress on the complex eigenvalue cases.
Reflections
Physical exercise really does help with mental blocks. Keep alternating between study and movement.
