Theory and practice
In theory there is no difference between theory and practice, but in practice there is.
• Theory: everything is clear, but nothing works;
• Practice: everything works, but nothing is clear;
• Sometimes theory meets practice: nothing works and nothing is clear.
Отсюда, м.б.
Experts have failed to make theory and practice meet?..
