By Peter Woit

At what aspect does thought go away the world of testable speculation and are available to resemble whatever like aesthetic hypothesis, or maybe theology? The mythical physicist Wolfgang Pauli had a word for such principles: He might describe them as "not even wrong," that means that they have been so incomplete that they can no longer also be used to make predictions to match with observations to work out whether or not they have been improper or now not. In Peter Woit's view, superstring concept is simply such an concept. In Not Even Wrong , he exhibits that what many physicists name superstring "theory" isn't really a concept in any respect. It makes no predictions, even unsuitable ones, and this very loss of falsifiability is what has allowed the topic to outlive and flourish. Not Even Wrong explains why the mathematical stipulations for growth in physics are totally absent from superstring concept this present day and exhibits that judgments approximately medical statements, which could be in response to the logical consistency of argument and experimental facts, are as an alternative in keeping with the eminence of these claiming to grasp the reality. within the face of many books from lovers for string thought, this publication offers the opposite part of the tale.

The Last Sorcerers: The Path from Alchemy to the Periodic Table

THEY all started WITH 4: earth, air, fireplace, and water. From those fundamentals, they sought to appreciate the basic components of the area. those that might see additional, those that understood that the 4 have been only the start, have been the final sorcerers -- and the world's first chemists.
What we now name chemistry begun within the fiery cauldrons of mystics and sorcerers looking to not make a greater global via technological know-how, yet quite to make themselves richer via magic formulation and con video games. but between those early magicians, frauds, and con artists have been a couple of far-seeing "alchemists" who used the trial and mistake of rigorous experimentation to rework mysticism into technological know-how.
Scientific historians in general credits the nice 18th century French chemist Antoine Lavoisier with modernizing the sector of chemistry. Others may stick to his lead, conscientiously interpreting, measuring, and recording their findings. 100 years later, one other pioneer emerged. Dimitri Mendeleev, an eccentric genius who minimize his flowing hair and beard yet annually, eventually introduced order to the chemical sciences while he developed the 1st Periodic desk within the past due 1800s.
But among and after Lavoisier and Mendeleev have been a number of alternative colourful, very good scientists who made their mark at the box of chemistry. Depicting the vigorous careers of those scientists and their contributions whereas rigorously deconstructing the historical past and the technological know-how, writer Richard Morris skillfully brings all of it to existence. Hailed through Kirkus studies as a "clear and vigorous author with a penchant for down-to-earth examples" Morris's reward for rationalization -- and natural leisure -- is amply visible. Taking a cue from the nice chemists themselves, Morris has brewed up a powerful mix of the alluringly imprecise and the traditionally momentous, spiked with simply the proper dose of quirky and ribald element to carry a paranormal brew of heritage, technology, and personalities.

The ghosts of evolution : nonsensical fruit, missing partners, and other ecological anachronisms

A brand new imaginative and prescient is sweeping via ecological technological know-how: The dense internet of dependencies that makes up an environment has received an further dimension-the size of time. each box, woodland, and park is stuffed with dwelling organisms tailored for relationships with creatures which are now extinct. In a bright narrative, Connie Barlow exhibits how the belief of "missing companions" in nature developed from remoted, curious examples into an idea that's reworking how ecologists comprehend the total natural world of the Americas.

Example text

This search for understanding has taken a variety of forms: one is religion, one is art, and one is science. Although the word science comes from the Latin verb meaning “to know,” science has come to mean not merely knowledge but specifically knowledge of the natural world. Physics attempts to describe the fundamental nature of the universe and how it works. It is the science of matter and energy, space and time. Like all science, physics is a body of knowledge organized in a specific and rational way.

S S S S S S vector addition. An equivalent way of adding vectors, called the parallelogram method, inS S volves drawing B so that it is tail-to-tail with A (Figure 1-7). A diagonal of the S S S parallelogram formed by A and B then equals C as shown (Figure 1-7). As you can see in the figure, it makes no difference in which order we add two vectors; S S S S that is, A ϩ B ϭ B ϩ A . Therefore, vector addition obeys the commutative law. S S S To add more than two vectors—for example, A , B , and C —we first add two vectors (Figure 1-8), and then add the third vector to the vector sum of the first two.

For example, the length of this book is a physical quantity, as is the amount of time it takes for you to read this sentence and the temperature of the air in your classroom. Measurement of any physical quantity involves comparing that quantity to some precisely defined standard, or unit, of that quantity. For example, to measure the distance between two points, we need a standard unit of distance, such as an inch, a meter, or a kilometer. The statement that a certain distance is 25 meters means that it is 25 times the length of the unit meter.
