2012 retail book of 2000 hardcover The stressed Sea
A brilliant, up to date journey of the Earth's final frontier, a distant and mysterious realm that still lies with reference to the guts of even the main land-locked reader.
The sea covers seven-tenths of the Earth, yet we've got mapped just a small percent of it. the ocean comprises thousands of species of animals and vegetation, yet now we have pointed out just a couple of thousand of them. the ocean controls our planet's weather, yet we don't fairly know the way. the ocean remains to be the frontier, and but it kind of feels so widespread that we occasionally fail to remember how little we all know approximately it. simply as we're poised at the verge of exploiting the ocean on an unheard of scale—mining it, fertilizing it, fishing it out—this ebook reminds us of the way a lot we have now but to benefit. greater than that, it chronicles the information explosion that has remodeled our view of the ocean in precisely the prior few a long time, and made it a much more fascinating and available position. From the massive Bang to that distant destiny time, billion years from now, whilst our planet might be a waterless rock; from the plush crowds of lifestyles at seafloor scorching springs to the invisible, jewel-like crops that go with the flow on the sea floor; from the stressed transferring of the tectonic plates to the majestic sweep of the sea currents, Kunzig's transparent and lyrical prose transports us to the ends of the Earth.

With the exception of the virus of rabbit papilloma, whose particles when air-dried show signs of surface nodules in regular array (Williams, 1953c), no surface detail of any apparent significance has been detected upon any virus. The reasons for this failure are not clear. The electron microscope has a resolving power sufficient to allow discernment to be made of structural irregularities of the order of 20 b in size, if sufficient electron contrast is available. So far, contrast can be introduced into the images of intact virus particles only by the enhancement of topographical detail through shadowing methods.

The nucleic acid is shown a t a radius of 40 A. Our results therefore suggest that the molecular weight of TMV is about 40 x lo6. This is in good agreement with the values obtained by Schramm and Bergold (1947) using 44 ROSALIND E. FRANKLIN, A. KLUGAND K. C. HOLMES sedimentation and diffusion measurements, and by Oster, Doty and Zimm (1947) and Oster (1950) using light-scattering measurements. On the other hand Williams, Backus and Steere (1951), using a direct method involving weighing and electron microscope measurements, found the particle weight to be 50 x lo6.
