Ets spherical but asteroids not Often the size of an object is determined by something simple but uite unexpected The size of a cell and a star depend in part on the ratio of surface area to volume The divide between the size of a spherical planet and an irregular asteroid is the balance point between the gravitational forces and the chemical forces in nature Most importantly with a very few basic principles it all makes sense The world really is a most reasonable plac. S a little bewildering to me the author runs up and down the scales for a few chapters discussing measurement methods for different applications and then runs up and down again talking about the contents of the universe than the means of investigation But within these broad divisions things are still all mixed together the astronomer s cosmic ladder for instance is covered close to the end of the book and
the startling importance of the weak force has to wait to the final page However this variegated smorgasbord approach retained startling importance of the weak force has to wait to the final page However this variegated smorgasbord approach retained interest throughoutA few cavils The little diagrams heading the chapters are uncomfortably small and would have been easier to read printed up the page instead of across I docked a star because the editing should have been better I spotted forty odd typos and such including a couple of clangers if Edmond Halley had indeed observed the transit of Mars rather than Mercury he must have. Narrative that trips its way from stellar magnitudes to the clocks on GPS satellites from the nearly logarithmic scales of a piano keyboard through a system of numbers invented by Archimedes and on to the measurement of the size of an atom Why do some things happen at certain scales Why are cells a hundred thousandths of a meter across Why are stars never smaller than about 100 million meters in diameter Why are trees limited to about 120 meters in height Why are plan. .

Includes a nice discussion of how the
fundamental forces of nature determine the size of objects Fun journey from the planck length to theforces of nature determine the size of objects Fun journey from the planck length to the of the observable universe A primer not only in numbers but in math physics and history I enjoyed it though it is at times hard to follow This book explores the cosmos at all scales down through cells molecules atoms nuclei and uarks and up through planets stars nebulae and on to the edge of the observable universe Although much of material will be familiar to anyone interested in science approaching it along this axis is fruitful and interesting For instance it leads to observations on how the surface to volume ratio limits both the size of animals and the size of individual cells and picks out the odd gap on the number line between the size of the atom and that of the nucleus a scale at which nature has produced no objects at allThe book s structure wa. This book is about how big is the universe and how small are uarks and what are the sizes of dozens of things between these two extremes It describes the sizes of atoms and planets uarks and galaxies cells and seuoias It is a romp through forty five orders of magnitude from the smallest sub nuclear particles we have measured to the edge of the observed universe It also looks at time from the epic age of the cosmos to the fleeting lifetimes of ethereal particles It is ,
