[p. 29]

(Einstein)

[132]The

calculations

on [p. 29]

above the horizontal line

are

a

brief

summary

of

the

calculations

on

[p.

28].

The

perihelion

advance of

Mercury

in

the

field

of

a

static

sun

is

converted from

fractions

of

ir

per

half

a

revolution

to

seconds of

arc

per century (see

notes 128-131).

The

fact

that the

factor

Ac0/F

(see

[eq. 177]

and

[eq.

180]

on [p.

26])

is

dimensionless

is

checked.

[133]The

calculations

on

[p.

29]

below the horizontal

line

are

part

of the evaluation of the

perihelion

advance of

Mercury

in

the

field

of

a

rotating sun.

The

same

calculations

can

be

found

on [pp.

34-35] (see notes 153

and

162).

[Eq.

182]

should

have

R2 instead of R3

(see [eq.

205]

on [p.

34]).

[Eq.

183]

is

equivalent

to

[eq.

207] on

[p.

34]

and

[eq.

212] on

[p.

35].

The

numbers

to

the

right

give

the radius

R

of

the

sun

in

terms

of the radius

Re

=

6.4

.

108

cm

of the Earth

(see notes 155

and

162).
