Once upon a time 'The Scientific Revolution of the 17th century' was an innovative concept that inspired a stimulating narrative of how modern science came into the world. Half a century later, what we now know as 'the master narrative' serves rather as a strait-jacket — so often events and contexts just fail to fit in. No attempt has been made so far to replace the master narrative. H. Flori…
Crystallography is the experimental science of the arrangement of atoms in solids. The word "crystallography" derives from the Greek words crystallon = cold drop / frozen drop, with its meaning extending to all solids with some degree of transparency, and grapho = write. Unit cell is the smallest unit of volume that permits identical cells to be stacked together to fill all space. By repeating…
Biodiversity and environmental biobanks, which can stand by themselves or can be housed at e.g., natural history collections, botanical gar-dens, zoos/aquaria, or culture collections, are essential infrastructures not only to preserve and provide samples from different groups of organ-isms but also to sustain innovation, food security, natural resource management, biotech…
This book examines how our understanding of human sexuality and human body changes through the processes of mediation unfolding at the intersection of nonhuman life and the Internet.

In this chapter, we study the physics of wave motion. We concentrate on mechanical waves, which are disturbances that move through a medium such as air or water. Like simple harmonic motion studied in the preceding chapter, the energy transferred through the medium is proportional to the amplitude squared. Surface water waves in the ocean are transverse waves in which the energy of the wave tra…
As expected, the velocity increases when the tension increases, and decreases when the mass increases. An 80.0-m-long, 2.10-mm-diameter copper wire is stretched between two poles. A bird lands at the center point of the wire, sending a small wave pulse out in both directions. The pulses reflect at the ends and arrive back at the bird’s location 0.750 seconds after it landed. Determine the ten…

Cells are the basic building blocks of all living things. The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. Cells also contain the body’s hereditary material and can make copies of themselves. Cells have many parts, each with a different function. Som…
Turtles are in the class Reptilia, which includes snakes, crocodiles, and lizards. Marine turtles belong to the order Testudines, the first specimens date back 220 million years. Marine turtles are thought to have come from land turtles and freshwater turtles that lived about 230 million years ago in the Cretaceous period. The earliest sea turtle ancestor found so far is Desmatochelys padil…
Information about cattle instincts and associated behavior is a valuable tool that helps producers understand why cattle behave or respond as they do. Although cattle have been domesticated for a very long time, they are dictated by the herding instinct, especially if they perceive a dangerous situation. Cattle depend heavily upon sight, and they have a nearly 360-degree panoramic view. This vi…
