A starry sky with the Milky Way galaxy(thanks to Bernd Nies) Early astronomy The very earliest people, as early as six million years ago, knew much more about the moon and the planets and the stars than most people do today. That's because they lived mainly outside, without electric lights blocking out the sky, and they saw every night how the moon and [...]

What is inertia? Physics – Science

The bus is heavy, so it's hard to get it moving. A law of physics first suggested by the Uzbek scientist Ibn Sina about 1000 AD states that "an object at rest tends to remain at rest, and an object in motion tends to remain in motion." Scientists call these tendencies inertia. Inertia is a way of measuring [...]

The ballet dancer Misty Copeland jumps high by pushing off the floor. As with the First and Second Laws of Motion, an Islamic scientist was the first to propose the  Third Law of Motion too. Ibn Bajjah, who lived in Islamic Spain, was a physicist. He lived in the 1000s, a little later [...]

How hard will the ball hit the catcher's glove? It depends how big the ball is. how fast the pitcher throws it, and how far away the catcher is. Like the First Law of Motion, the Second Law of Motion started out with work in the medieval Islamic Empire, about 1000 AD in [...]

Newton’s First Law of Motion – Physics

Isaac Newton, mathematician and physicist About 1000 AD, in the Islamic Empire, Ibn Sina came up with the idea that an object moving in a vacuum would just keep moving forever without slowing down. But to prove this was always true, you'd need calculus, which hadn't been invented yet. In the 1700s, Isaac Newton figured out [...]

Newton’s Laws of Motion – Movement – Physics

Light takes years to reach us from these stars far away in space. When solid objects move through space, they follow certain rules that let us predict how they will act. We call the first three rules Newton's Laws of Motion, and they say that: An object in motion tends to remain in motion, and an [...]

Gravity is an important cause of acceleration Newton's Second Law of Motion tells us that force equals mass times acceleration. You can try this out for yourself. Here's a website with a good experiment you can do. More about the Second Law of Motion More about Ibn Sina Bibliography and further reading about Newton's [...]

Voltaire – European philosopher

Voltaire - a French philosopher Voltaire took ideas about religion, science, and human rights that were just getting started in the 1700s AD, and encouraged new ways of thinking about them. His ideas paved the way for the American Revolutionary War and the French Revolution, though he died just before the French Revolution. Voltaire was [...]
