WSJ Opinion Editorial (Originally Published on
July 19th)
What We’ve Learned from the Gulf Spill
In the future, relief wells should be drilled
simultaneously with the main well.
by Michio Kaku
If the oil leak in the Gulf of Mexico were a
tragedy, it would be in three acts. In Act I,
there was the chaos caused by a methane
explosion that killed 11 workers and unleashed
the greatest environmental catastrophe in U.S.
history. In Act II, we saw the floundering of BP
officials, as eight failed attempts were made to
cap, siphon, stuff, smother or seal the leak.
We are now slowly entering Act III, where
engineers have painfully learned some valuable
lessons and are on the verge of slowly killing
this raging monster.
The nagging question is: Why did it take so
long? Why couldn’t they have capped the leak
months ago?
For three agonizing months, BP’s engineers
and executives were essentially making things up
as they went along, conducting a billion dollar
science project with the American people as
guinea pigs. The basic science of stopping oil
leaks at 5,000 feet below sea level should have
been done years ago.
All eight failed attempts to control the leak
might have worked if the blowout had taken place
at 200 feet. The 1979 Ixtoc oil leak in Mexico,
which was the mother of all oil disasters, took
place at 160 feet and raged for 10 months. It
was eventually stopped by a relief well. The
lessons learned from that and other oil
disasters gave confidence to engineers in the
industry that they could handle any leak.
Physics are different at 5,000 feet than they
are at 200 feet. The pressure at 5,000 feet is
enormous, about 2,000 pounds per square inch.
Think of placing a passenger car on every square
inch of your chest. You would be crushed like an
egg shell within a fraction of a second. Even
military submarines cannot operate at those
depths. Instead, special remote controlled
robotic subs are required. They are often hard
to control and sometimes even collide.
Furthermore, methane, which is found as a gas
in our kitchen stoves, solidifies into an
ice-like hydrate at those tremendous depths and
cold temperatures. The original explosion, it is
conjectured, was caused when heat was applied to
set the well’s cement seal, expanding the
methane hydrates into gas that shot up the riser
pipe and ignited. The presence of methane
hydrates also foiled the first attempt to cap
the leak. Later, BP engineers had greater
success by sending warm water down the pipe to
prevent methane hydrates from clogging it
without creating gas bubbles like the one that
caused the explosion.
BP officials initially low-balled the size of
the leak. Although they originally stated that
1,000 barrels of oil were leaking per day, they
also released video that gave a startlingly
different picture.
In our freshman physics courses we teach the
students that the flow rate from a pipe is the
product of the area of the pipe times the
velocity of the fluid. You don’t have to be a
rocket scientist to multiply these two numbers.
Even a simple back-of-the-envelope estimate of
the leak from watching the video will give you
estimates of 40,000 to 60,000 barrels of oil per
day. Did BP officials knowingly release
misleadingly low figures, perhaps because they
can be fined more than $4,000 per barrel by the
U.S. Environmental Protection Agency?
In the future there should be much tighter
controls on deep-water drilling, and there
should be redundant systems on hand so that the
well can be capped or siphoned immediately if
the blowout preventer fails. Perhaps relief
wells should be drilled simultaneously with the
main well, since they are the gold standard for
stopping oil leaks and work nearly without fail.
There also has to be a standby fleet of ships
with skimmers, centrifugal pumps and booms ready
to handle oil once it is leaked.
More importantly, the basic science of
plugging oil leaks at great depths has to be
completed, so that any future tragedies will not
be repeated as farce. Until we end our oil
addiction and develop alternative energy
sources, similar plotlines will no doubt recur.

I’m
nearly done filming a second season of “SCI-FI
Science: Physics of the Impossible” on The
Science Channel. In this exciting new series,
I’ve identified 12 more familiar science-fiction
movie, TV and literature notions and
technologies. I’ve been explaining how we can
build some of these SCI-FI ideas into science
fact and — once again — I want to know what YOU
think of my designs.
The next two episodes will be: ”How
to Stop the Rise of the Machines” and “How

“In fact, it is
often stated that of all the theories
proposed in this century, the silliest
is quantum theory. Some say that the
only thing that quantum theory has going
for it, in fact, is that it is
unquestionably correct.”
Almost since its inception, the
development of quantum theory has been
built by some of the greatest minds of
their day. Some of the framework for
this theory can be traced back to the
following discoveries:
– In 1897 the discovery of the
electron proved there were individual
particles that make up the atom.
There was brief
speculation in the media about using
nuclear weapons to seal up the raging
oil leak in the Gulf of Mexico. I think
this is a bad idea, from a physics point
of view. Let me say that my mentor while
I was in high school and at Harvard,
Edward Teller, father of the H-bomb, was
a firm advocate of using nuclear weapons
to dig out canals and other grand
engineering projects. The logic is
this: when an H-bomb is detonated
underground, most of its energy is in
the form of soft X-rays, which deposit
most of their energy in a large sphere,
where it is absorbed and the energy
turned to intense heat. (In the air,
this ball of hot ionized plasma rises
rapidly, with cold air coming in from
the side, which gives rise to the
familiar mushroom cloud).
Up until just a few
hundred years ago most people thought
that the Universe was a stable, static
place that had been here forever and
would continue forever. Today we know
that nothing could be further from the
truth. In reality, we know that the
Universe is a violent and continually
changing place that was born in a mere
nanosecond of time in the spectacular
event we call the Big Bang. You may have
heard the Big Bang referred to as the
mother of all explosions but it wasn’t
an explosion so much as an expansion.
From a space that was infinitely small,
the entire Universe expanded and
continues even to this day -13.7 billion
years later.
Water and Organic
Compounds Found on a Second Asteroid - The headlines
were swamped again, on Friday as scientists confirmed
the discovery of water ice and organic molecules on a
second asteroid (65 Cybele) in the same region of the
asteroid belt. Although the asteroids only contain very
thin layers of ice, they suggest that water may be quite
common on asteroids after all.
Graphene Will
Change the Way We Live - Some say that it will be
heralded as one of the materials that will literally
change our lives in the 21st century. Not only is
graphene the thinnest possible material that is
feasible, but it's also about 200 times stronger than
steel and conducts electricity better than any material
known to man—at room temperature.
Found: The
Holy Grail of Planetary Science - Recently, a nearby
earth-like twin was found in outer space—perhaps capable
of harboring life. The planet is called Gliese 581g, and
is 20 light years from Earth (about 120 trillion miles).
In width, it is about 20% to 30% or so bigger than the
Earth, but weighs about 3 to 4 times more. What is
exciting is that the planet is inside the Goldilocks
zone—meaning it is not too close to its sun (where water
would boil) or too far (where water would turn to ice),
but just right to have liquid water, one of the most
precious substances in the Universe.
Kaku was born in
San Jose, California to
Japanese
immigrant parents. Reflecting on his childhood, he said:[1]
his grandfather had come to the United States to take part in the
clean-up operation after the
1906 San Francisco Earthquake. His father was born in California,
but received education in Japan, so spoke little English. Both his
parents were put in the
Tule Lake War Relocation Center, where they met and where his
brother was born.
He has published research articles on
string theory from 1969[citation
needed] to 2000. In 1974, along with Prof. K. Kikkawa, he
wrote the first paper on string field theory, now a major branch of
string theory, which summarizes each of the five string theories into a
single equation. In addition to his work on string field theory, he also
authored some of the first papers on multi-loop amplitudes in string
theory, the first paper on the divergences of these multi-loop
amplitudes, the first paper on
supersymmetry breaking at high temperatures in the early universe,
the first paper on super-conformal gravity, and also some of the first
papers on the non-polynomial closed string field theory. Many of the
ideas he first explored have since blossomed into active areas of string
research. His most recent research publication, on bosonic quantum
membranes, was published in Physical Review in 2000.
In
Physics of the Impossible, he examines the technologies of
invisibility, teleportation, precognition, star ships, antimatter
engines, time travel and more—all regarded as things that are not
possible today but that might be possible in the future. In this book,
he ranks these subjects according to when, if ever, these technologies
might become reality. In March 2008, Physics of the Impossible entered
the
New York Times best-seller list, and stayed on for five weeks.
Kaku has publicly stated his concerns over matters including the
human cause of
global warming,
nuclear armament,
nuclear power and the general misuse of science.[4]
He was critical of the
Cassini-Huygens
space probe because of the 72 pounds of
plutonium contained in the craft for use by its
radioisotope thermoelectric generator. Conscious of the possibility
of casualties if the probe's fuel were dispersed into the environment
during a malfunction and crash as the probe was making a 'sling-shot'
maneuver around earth, Kaku publicly criticized NASA's risk assessment.[5]
He has also spoken on the dangers of
space junk and called for more and better monitoring. Kaku is
generally a vigorous supporter of the exploration of outer space,
believing that the ultimate destiny of the human race may lie in the
stars; but he is critical of some of the cost-ineffective missions and
methods of NASA.
Kaku credits his anti-nuclear
war position
to programs he heard on the
Pacifica Radio network, during his student years in California. It
was during this period that he made the decision to turn away from a
career developing the next generation of nuclear weapons in association
with Dr. Teller and focused on research, teaching, writing and media.
Dr. Kaku joined with others such as Dr.
Helen Caldicott,
Jonathan Schell,
Peace Action and was instrumental in building a global anti-nuclear
weapons movement that arose in the 1980s, during the administration of
US President
Ronald Reagan.
Kaku was a board member of
Peace Action and on the board of radio station
WBAI-FM in New York City where he originated his long running
program, Explorations, that focused on the issues of science, war, peace
and the environment.
In 1999, Kaku was one of the scientists profiled in the
feature-length film, Me and Isaac Newton, directed by
Michael Apted. It played theatrically in the United States, was
later broadcast on national TV, and won several film awards.
In 2005 Kaku appeared in the short documentary
Obsessed & Scientific. The film is about the possibility of time
travel and the people who dream about it. It screened at the Montreal
World Film Festival and a feature film expansion is in development
talks. Kaku also appeared in the ABC documentary UFOs: Seeing Is
Believing, in which he suggested that while he believes it is extremely
unlikely that extraterrestrials have ever actually visited Earth, we
must keep our minds open to the possible existence of civilizations a
million years ahead of us in technology, where entirely new avenues of
physics open up. He also discussed the future of interstellar
exploration and alien life in the Discovery Channel special
Alien Planet as one of the multiple speakers who co-hosted the show,
and Einstein's Theory of Relativity on The History Channel.
In February 2006, Kaku appeared as presenter in the BBC-TV
four-part documentary
Time which seeks to explore the mysterious nature of time. Part one
of the series concerns personal time, and how we perceive and measure
the passing of time. The second in the series deal with cheating time,
exploring possibilities of extending the lifespan of organisms. The
geological time covered in part three explores the ages of the earth and
the sun. Part four covers the topics of cosmological time, the beginning
of time and the events that occurred at the instant of the big bang.
On January 28, 2007, Kaku hosted the Discovery Channel series
2057. This three-hour program discussed how medicine, the city, and
energy will change over the next 50 years. In 2008, Kaku hosted the
three-hour BBC-TV documentary Visions of the Future, on the future of
computers, medicine, and quantum physics, and appeared in several
episodes of the History Channel's Universe series.
On Dec. 1, 2009, he began hosting a 12-episode weekly TV series
for the Science Channel at 10 pm, called "Sci
Fi Science: Physics of the Impossible," based on his best-selling
book. Each 30 minute episode discusses the scientific basis behind such
imaginative schemes as: time travel, parallel universes, warp drive,
star ships, light sabers, force fields, teleportation, invisibility,
death stars, and even superpowers and flying saucers. Each episode
includes interviews with the world's top scientists working on
prototypes of these technologies, interviews with sci fi fans, clips
from science fiction movies, and special effects and computer graphics.
Although these inventions are impossible today, the series discusses
when these technologies might become feasible in the future.[6]
In 2010, he began to appear in a series on the website
Gametrailers.com called 'Science of Games', discussing the scientific
aspects of various popular video games such as
Mass Effect 2 and
Star Wars: The Force Unleashed.
Kaku is popular in mainstream media because of his knowledge and
his accessible approach to presenting complex subjects in science. While
his technical writings are confined to theoretical physics, his public
speaking and media appearances cover a broad range of topics, from the
Kardashev scale to more esoteric subjects such as
wormholes and
time travel. In January 2007, Kaku visited the Middle Eastern
country of Oman.
While there, he talked at length to select members of that country's
decision makers. In an interview with local media, Dr Kaku elaborated on
his vision of mankind's future. Kaku considers climate change and
terrorism as serious threats in man's evolution from a
Type 0 civilization to Type 1.[7]
Kaku is the host of the weekly, one hour radio program
Explorations, produced by the Pacifica Foundation's
WBAI in New
York. "Explorations" is syndicated to community and independent radio
stations and makes previous broadcasts available on the program's
website. Kaku defines the show as dealing with the general topics of
science,
war,
peace and
the
environment.
In April 2006, Kaku began broadcasting Science Fantastic on 90
commercial radio stations, the only nationally syndicated science
program on commercial radio in the United States. It is syndicated by
Talk Radio Network and now reaches 130 radio stations, and
America's Talk on
XM. The program is formatted as a live listener call-in show,
focusing on "futurology," which he defines as the future of science[citation
needed]. Featured guests include Nobel laureates and top
researchers on the topics of string theory, time travel, black holes,
gene therapy, aging, space travel, artificial intelligence and SETI.
Unfortunately, when Kaku is busy filming for television, Science
Fantastic goes on hiatus. Sometimes for several months. Kaku is also a
frequent guest on many programs where he is outspoken in all areas and
issues he considers of importance, such as the program "Coast
to Coast AM," where on 30 November 2007, he reaffirmed his belief
that there is a 100 percent probability of extraterrestrial life in the
universe.[8]
Kaku has appeared on the
Opie and Anthony show a number of times, discussing popular fiction
such as
Back to The Future,
Lost, and the theories behind time-travel that these and other
fictional entertainment focus on. Steven G. Spruill's novel
The Janus Equation,[9]
which describes the time travel of a post-op transsexual mating with her
past self and thereby becoming father and mother to her present self,
prompted Dr. Kaku's comment: "Well, you're in deep doo doo if that
happens."[10]
Physics of the Impossible is an exploration into the science people
dream about. Kaku explores things that people think are quite
impossible. This book is divided into three sections: Class I, Class II,
and Class III, according to the time that the things he talks about
might happen.
Parallel Worlds talks about the possibilities of the existence of
parallel worlds. Kaku also talks about black holes and other frequently
asked matters of advanced physics.
Beyond Einstein is a resource for people wanting to know more about
physics. Kaku mostly talks about Einstein and his quest for the
Theory of Everything.

Product Description:
Binary Economics presents a new paradigm which founds a
practical new economics and a unifying new politics that
enable people to understand and realize their essential
rights and responsibilities in a market economy. This
paradigm recognizes that capital has a potent productive
and distributive relationship to growth, and by
democratically extending the efficient means to acquire
capital to all people using the earnings of capital on
market principles, binary economics offers many
important benefits beyond those provided by conventional
economics. The authors present this concept as new hope
for solving seemingly intractable problems of economic
efficiency, distribution, and justice not solved by
conventional economic theories and practices, while
enabling people to understand and realize their
essential rights and responsibilities in a market
economy. The binary paradigm allows cooperation with
governments to make modest reforms to existing capital
markets so that all people can acquire capital using the
earnings of capital and offering the market foundation
for many important benefits, including substantial,
sustainable growth; more equal opportunity and social
justice; increased earning power for the poor, working
and middle class people; a greener environment;
individual autonomy; strong families and communities;
strengthened democracy; and voluntary control of
population levels.--This
