2. Why is the wave function ^ 2 = probability of electrons? No

reason.

6.17. Fluid mechanics

In fluid mechanics, the Navier Stokes equation proves to be
wrong.

6.18 Circuit Design Related

1. Confusion occurs when the voltage direction is opposite to the
current direction.

2. If there is no ground voltage and the current direction is
unknown, an error will occur.

6.19 More Technology

1. Fuel cells involve combustion and electrochemistry, so
wasting and no charging can be a problem.

2. Large-scale production of OLEDs requires the film to be

changed to a thick film.

6.20 Acceleration / Time

Acceleration/time is a new vocabulary that can be applied to
v(t)= ct ^ 3

V(t) is the speed t = time = time

Ex,1：v（t）= ct ^ 2 v（t）/ t = 2ct ;;Ex.2：v（t）= ct ^ 3

，v（t）/ t = 3ct ^ 2 v（t）/ t ^ 2 = 6ct t =time v（t）
=velocity

6.21 E in the tensile test formula
F = strength A = cross section area dL = length extension

L = original length
F/A = E dL/L
