So be there on Sunday June 8 5 p.m.
at the JFK auditorium UWI St. Augustine. [Wild applause and cheering for 22 seconds] [Philip Emeagwali Equations Explained] [What is Philip Emeagwali Famous for in Math?] I am often asked:
What are the Philip Emeagwali Equations?
Or, how were the Philip Emeagwali Equations derived?
The Philip Emeagwali Equations are a system of coupled, non-linear,
time-dependent, and three-dimensional partial differential equations
that are symbolic restatements in calculus of multi-phased fluids
flowing across a porous medium. The Philip Emeagwali Equations
encoded into calculus the Second Law of Motion of physics.
The Philip Emeagwali Equations model the three-phase,
three-dimensional flows of crude oil, natural gas,
and injected water that are flowing one mile deep
and flowing across an oilfield that is the size of a town.
I have been presenting the Philip Emeagwali Equations
to research mathematicians and doing so since the early 1980s.
The Philip Emeagwali Equations were the cover story
of the June 1990 issue of the SIAM News.
The SIAM News is the premier publication
for mathematicians. The SIAM News
is the flagship publication of the Society for Industrial
and Applied Mathematics. The SIAM News
presents new mathematical knowledge as written by research mathematicians
for research mathematicians. I also presented
the Philip Emeagwali Equations at invited lectures that I delivered to
research mathematicians in the United States.
I delivered an invited lecture on my contributions to mathematics
and I delivered that lecture to the largest international congress
of mathematicians, called ICIAM ’91.
That congress is the Olympics of the world of mathematics
and is held once every four years. My ICIAM ’91 lecture
was at eleven  in the morning of Monday July 8, 1991,
in the Dover Room of the Washington Sheraton Hotel
in Washington in the District of Columbia,
United States. The complete mathematical description of the
invention of the Philip Emeagwali Equations
is posted at emeagwali dot com and shared at the YouTube channel of Philip
Emeagwali. In summary,
the Philip Emeagwali Equations is akin in mathematical structure
to the iconic Navier-Stokes equations that were used to design jet aircrafts, and
used to model the flow of bloods flowing across veins and arteries.
Due to its importance, the Navier-Stokes equations
were used to define one of the seven millennium problems
of mathematics. The system of Navier-Stokes equations
own itself to the oceans, wind, and fire. Just like the system of
Philip Emeagwali equations own itself to the injected water,
crude oil, and natural gas that flows one mile deep
and flows inside an oilfield that is the size of a town. The differential equation
plays a central role in subdisciplines of mathematics,
such as complex analysis, Lie algebra theory
[pronounced /liː/ “Lee”], and probability theory.
My discovery of practical parallel processing
can be extended to all boundary value problems
of calculus that are governed by
partial differential equations, such as Maxwell’s equations
of electrodynamics, diffusion equation
of heat and mass transfer, beam and plate equations
of solid mechanics, lubrication theory of fluid mechanics,
Hodgkin-Huxley equations of neurobiology,
Fisher’s and reaction-diffusion equations of genetics and population dynamics,
and the Black-Scholes equation of financial engineering.
For these partial differential equations, the timescales
for discretizing and solving them range from one trillionth of a second
to a thousand years. And the length scales for solving them
range from the sub-atomic to the astronomical. [Millennium Equations Versus Philip Emeagwali
Equations] The various formulations
of the partial differential equations governing the flows of fluids
were almost independently derived by Claude-Louis Navier,
Siméon-Denis Poisson, Barré de Saint Venant,
and George Stokes. Those partial differential equations
were derived between 1827 and 1845. The Philip Emeagwali equations
were my independent derivations of new partial differential equations
that I formulated when I was a research mathematician
of the early 1980s and in College Park
(Maryland, United States). The Philip Emeagwali equations
were the governing equations that encoded the time-dependent
and three-dimensional subterranean motions
of crude oil, injected water, and natural gas
that flow one-mile deep and across an oilfield and towards
production oil wells. The mathematical difference between
the Navier-Stokes Equations as written in the millennium problem
of mathematics and the Philip Emeagwali Equations
is that the latter govern the three-dimensional,
three-phase fluids flowing across a porous medium
that is one mile deep and that is the size of a town.
Please allow me a couple of minutes to speak only
to the mathematicians in this audience. In most fluid dynamics textbooks,
the Navier-Stokes Equations are written in compact, vector form as: rho, the fluid density,
times the sum of the partial
of v, the fluid velocity in vector, with respect to the partial
of t, the independent variable time, (that is, the change in velocity
with respect to time that is called the temporal acceleration)
plus the product of the fluid velocity in vector
and nabla (or upside down delta
and the gradient operator) v, the fluid velocity in vector
(that is, the convective acceleration) is equal to
minus nabla p, the fluid pressure term (that is, the fluid flows
in the direction of the largest change in pressure),
plus the product of nabla and capital T
(where capital T is the stress tensor for viscous fluids)
plus f (the body forces
such as wind, gravity, and electromagneticism). I stated a vector equation
for each of my three phases, namely, crude oil, injected water,
and natural gas. That is equivalent
to nine scalar equations. My unknowns were the velocity
and the pressure. In three spatial dimensions,
I have three equations and four unknowns, namely,
the pressure and the three scalar velocities.
For that reason, I introduced a system of supplementary
partial differential equations. Those extra partial differential equations
encode the law of conservation of mass for the crude oil, natural gas,
and injected water phases. Those continuity equations
are the products of nabla
(or the gradient operator) and v,
the fluid velocity in vector equals
zero. [Wild applause and cheering for 17 seconds] Insightful and brilliant lecture
