Mystery of universe space
A quasar, the brightest type of object in the universe, is seen releasing massive amounts of energy as stars are shredded near the supermassive black hole of a galaxy in this artistic illustration. Credit: NASA/JPL-Caltech Quasars are the brightest objects in the universe, and display a mysterious diversity…
What laws did Isaac Newton make?
Isaac Newton laid the blueprints for his three laws of motion, still recited by physics students, in 1. Credit: Library of Congress When little baby Isaac was born in a Lilliputian English village, premature and small enough to fit into a quart pot, he wasn t expected to survive. To the probable dismay of some befuddled calculus and physics students the world over, Isaac Newton…

Galileo and Newton laws of motion
Towards a new world Model From Galileo to Newton: Physics Emerges Newton s Many Accomplishments BACKGROUND & TIMES 1. By the time Isaac Newton entered college, the scientific revolution of the 17th century was well underway. 2. Men like Copernicus, Kepler, Galileo, and Descartes had all helped develop a new view of nature. 3. When Newton went to Cambridge, everyone…

Universal gravitational constant Calculator
Gravity, one of the constants of life, not to mention physics, is less than constant when it comes to being measured. Various experiments over the years have come up with perplexingly different values for the strength of the force of gravity, and the latest calculation just adds to the confusion. The results of a painstaking 10-year experiment to calculate the value of “big…

What is gravitational field strength?
Gravity is the force that acts between any two masses, which means that you are actually attracted to all your friends, no matter how much you deny it! Fortunately we are usually strong enough to overcome the attraction because it only becomes strong enough for us to notice its effects when the masses involved become very large e.g. planets or stars. The force always attracts…

What is the gravitational constant?
Check your knowledge about how ESD can ruin your day. If there ever was a silent killer for electronic devices, it s ESD (electrostatic discharge). A little zap from a finger, a charged metallic part, or an IC tray can cause an inrush of current that can damage sensitive IC. Trust me, for I know. When replacing a hard drive on a computer some years ago, I powered it and found…
