Opinion

In this brief paper, we provide the calculation that shows how early American Infrastructure Ventures were financed to the optimum level [1].

Illinois Central RR

Bond Capital =$ 5M=-PV

705 miles of track @$20,000/mile

1/√2 x 2=2=14.14M=-PMT

Labour 3000 workers @$1.25/day x 6 days per week x 52 weeks per year=$1.17M/year

-PMT=$14.14+$1.17=$15,31M

i=5.983

n=9 years

FV=1.835=1/545=1/t

t²-t-1=E

5448²-5448-1=296=1-0.704≈1/1/√2

E=1-t

1/t=1-t

1=t-t²

t²-t-1=0 GMP

Conclusion

Economics follows the same laws as Physics. The GMP is ubiquitous.
