The sketches, of course, were beautiful. But what really struck me was the sheer breadth of this one man's talents. da Vinci wrote treatises on physics, anatomy, astronomy, warfare, art, and other topics. Without a formal education, da Vinci never mastered Latin, the language in which academic treatises were written at that time. Some scholars dismissed his work.

da Vinci replied that he was a "disciple of experience":

"[They may say] I'm a man without learning, [but] I will cite something far more worthy, quoting experience..."

In another essay, da Vinci writes that

...the subjects I am dealing with are to be dealt with by experience rather than by words, and experience is the muse of all who write well. And so, as my muse, I will cite her in every case.

500 years ago, da Vinci understood the power of experience. Academic pedigree is fine, but a direct grasp of experience is essential. Analyzing and learning from direct experience is innately more powerful than hiding behind obscure academic methods. da Vinci "got it." Maybe he was the first.

500 years later, there are still those academics whose frameworks, methods, and terminology talk *about* experience but don't help much in bringing people to an understanding of the experience itself. Remember the Italian scholars who were so concerned with da Vinci's knowledge of Latin (the "method" of the day) that they completely missed (or dismissed) his genius - and didn't help others to see it.

About 94 percent of life on Earth resides in the oceans. We've seen only about 2 percent of this vast ecosystem - the uppermost layer (home to fish, whales, scuba divers, and most known marine life). Beneath this warm lens lies a cold, dark, and life-rich realm of grand proportions. It's home to creatures as far removed from the sun and human biology as any alien imagined by science fiction.

We've seen some of these organisms clustering around midocean thermal vents - small undersea volcanoes that spew 400-degree water spiked with toxic chemicals. Thriving in total darkness, under 8,000 psi of ambient pressure, these organisms possess metabolic processes fundamentally different from ours. The ones we know about rely on chemosynthesis, using sulphides and other chemicals from Earth's core to convert seawater into food. That's about as alien as it gets.

Currently, the entire US scientific community shares a single, 12-year-old submersible named Alvin. With just one Alvin, long-range exploration is nearly impossible. Alvin doesn't even know where to go because we don't have a decent map. The latest ocean charts rely on satellites to detect the sea-level changes wrought by the gravitational pull of underlying topography. This gives us a crude sketch that's essentially useless without hands-on exploration. We can't begin to mine the sea's minerals or harvest DNA unless we go deep, with a fleet of sea exploration vessels. We need a national agency with the stated goal of exploring, mapping, and studying the oceans.

Japan is already there, having created the Japan Marine Science and Technology Center, which secures rights to deep-sea minerals, territories, and potential food sources. Its Deep Star program has even taken an early lead in DNA recovery: It's already working with the biotech industry to develop pharmaceuticals. Meanwhile, we're still combing the rain forests and wishing upon a star.
