There were a few aha! Lists with This Book.

The Strange Story of the Quantum. Mar 01, Lage von Dissen rated it it was ok. Galileo also gworge that a massive iron ball and a much lighter wooden ball roll down side grwvity side if released simultaneously from the same height on the same inclined plane.

Litt teknisk, litt matematikk, ordentlige forklaringer – uten overdrivelser og sensasjonelle beskrivelser. In earlier times the earth would have been nearer the sun and therefore hotter than it is now. It is difficult to conceive of a curved three-dimensional space, let alone a curved four-dimensional space-time, but some idea of what it means can be gained from an analogy with two-dimensional surfaces.

If geometrical figures are drawn on curved surfaces, for geotge a sphere or a surface shaped like a saddle, many of the Euclidean theorems do not hold.

He gently leads the reader through the mathematics of gravity. Readers averse to equations can skip the discussion of the elementary principles of calculus and still achieve a highly satisfactory grasp of a fascinating subject. Newton stated that the rate of change of velocity acceleration of an object is directly proportional to the force acting on it and inversely proportional georgf its mass.

That theory is based on the postulate that no observations made inside an enclosed chamber can answer the question of whether the chamber is at rest or moving along a straight line at constant speed. You can remove the unavailable item s now or we’ll automatically remove it at Checkout.

Here the steepness of the arc along which the weight travels is adjusted by changing the length of the string. Ratings and Reviews 0 2 star ratings 0 reviews.

If the sum of the angles is equal to degrees, the space is said to be flat. Now they will move side by side, each with a velocity equal to that of the spaceship at the moment of release. In fact, if the acceleration is equal to the acceleration of gravity on the surface of the earth, the passengers may well believe that their ship is still standing on its launching pad.

It should be pointed out that the ratio is a pure number, one that remains unchanged no matter what system of units is used for measuring the various physical quantities. Untypically for popular science books, this one is enhanced by the author’s own delightful sketches.

It seems, at least to the author, that the true relation between gravitational and electromagnetic forces is to be found gravty through an understanding of the nature of elementary particles-an understanding of why there exist particles with just certain inertial masses and not others-and of the relation between the masses and the electric and magnetic properties of the particles.

From Galileo to Newton to Einstein, Gamow explores this fundamental force in nature giving a brief overview of the science and history behind it. Letting balls roll down planes georgw at various angles, he observed their rates of travel and the distances covered in different time intervals, which he measured with a water clock. Faber Limited preview – In the Author’s Own Words: Although the “actual” distance is somewhat longer, the increase is more than compensated for by the smaller shrinkage of each yardstick.

This book is about gravity. Your display name gsorge be at least 2 characters long.

Gravity, by George Gamow [Special Archive Article] – Scientific American

However, the “unified field” theory, which grew out of this conviction, had hard going, and Einstein died without producing anything so simple, elegant and convincing as his earlier work.

The greater the muzzle velocity, the farther away from the mountain the bullet will land.

How to write a great review. Hence the pattern of fluorescent spots shows the floor approaching the light beam at an increasing rate. Graced with the author’s own drawings, both technical and fanciful, this remarkably reader-friendly book focuses particularly on Newton, who developed the mathematical system known today as the differential and integral calculus.

Imagine a grafity of light propagating across the space laboratory in a “horizontal” direction.

Surely this force must be capable of an experimental relation to electricity, magnetism and other forces, so as to build it up with them in reciprocal action and equivalent effect. Galileo, the first to take a close look at the process of free and restricted fall; Newton, originator of the concept of gravity as a universal force; and Einstein, who proposed that gravity is no more than the curvature of the four-dimensional space-time continuum.

Hence we can say that the space around the sun is positively curved. This question, which is as georte as the quantum theory, was ggeorge answered two years ago by the British physicist P.

Otherwise an iron and a wooden ball of the same size would not fall at the same rate. In Gravity, he takes an enlightening look at three of the towering figures of science who unlocked many of the mysteries behind the laws of physics: It’s a good book, kind of primer for seriously interested lay-reader, though quite a bit dated.

Jan 29, Paracelsus rated it it was amazing.

In the past few years it has become clear that the interactions of matter fall into distinct classes: As another way to dilute free fall he employed simple pendulums-weights suspended by ggavity strings. Not until half a century after Newton’s death was the existence of such a force demonstrated experimentally by another British genius, Henry Cavendish. More thorough analysis indicates, however, that this is not the case and that gravitational waves, weak though they may be, are real.
