To define the coefficient of linear expansion     We have seen that various substances do not expand equally when their temperatures are raised ( see useful Applications of thermal expansion ). Their properties in this respect are expressed by the coefficient of linear expansion , which is defined as follows. The coefficient of linear expansion of a substance is the fraction of its original length by which a rod of the substance expands per degree rise in temperature. Let's see an...Read Full Story

Gravitational force    The force of which we are constantly aware in our daily lives is that which pulls us towards the earth. This is called gravitational force . Sir Isaac Newton came to the conclusion that gravitational force exists between all bodies. Thus, two stones are not only attracted towards the earth but also attract each other. Normally, we do not notice this force owing to its smallness, although it can be measured with sensetive instruments. Nevertheless, two 50000 t ships...Read Full Story

A huge collection of manuscripts and notes by pioneering scientist Sir Isaac Newton are being made available online by Cambridge University Library. More than 4,000 pages -- just a fraction of the university's Newton archive -- have been digitized so far. The collection has been painstakingly conserved and photographed, and will now be available to students and historians all over the world, via the University's digital library. Mathematician and physicist Isaac Newton (1642...Read Full Story

About James Joule James Prescott Joule   James Prescott Joule (1818–1889), Scotland.   James Prescott Joule was one of five children in the family of a well-to-do brewery owner. Since he was a sickly child with a spinal deformity, both he and his brother were educated at home until the age of 15 and later by private tutors.    The famous English chemist, John Dalton , taught them chemistry, physics, and the methods of scientific experimentation .    Later...Read Full Story

It isn’t a rarity for the folks at the University of Cambridge to introduce us to some of their digital findings, and on this occasion they are delivering 4,000 of Newton’s manuscripts right to your virtual door. These gems are part of an abundant collection of over 12,000 handwritten notes and hardcovers that the University holds under possession — the plan is to make the entire selection digitally available “over the next few months.” Amongst the scanned documents, you’ll be able to find a...Read Full Story

   Hi, I hope you are fine:)         T oday is a new day. This is a great branch of classical mechanics, fluid mechanics .     We'll begin our course with The principle of Archimedes.       W hen it was first proposed to build ships made of iron many people laughed at the suggestion. Owing to the fact that a piece of iron sinks when placed in water they held the view that iron ships would be a failure.       W hen anything is placed in a liquid it receives an...Read Full Story

"This most beautiful system [The Universe] could only proceed from  the dominion of an intelligent and powerful Being."   Sir Isaac Newton What is Gravity ? The Discovery post says, " some scientist theorize that gravity is caused by particles called gravitons, most agree that gravity is a product of mass. Everything with mass, from a dust mote to a star, exerts a gravitational pull."  I say, we are made of mass too, and exert similar universal gravitation. Referred to as " G ," gravity...Read Full Story

Celebrations are in order, and not just for Christians. Atheists have appointed a new birthday to celebrate. Sir Isaac Newton shares his birthday with Jesus only quite a few years later in 1642. Atheists praise science and knowledge on December 25th. Elisha Goodman Click Here - Download Free Christian OffersRead Full Story
