What is tuberculosis? History of diseases

By |2018-04-18T18:18:04+00:00September 7th, 2017|Science, West Asia|

A child with tuberculosis Tuberculosis is a lung disease caused by germs. Today we can usually cure it with antibiotics. But in antiquity there was no cure. Many people died of tuberculosis. One kind of tuberculosis seems to have infected people since the Paleolithic. It came to North America and South America with the first people, about 13,000 BC. This tuberculosis [...]

A kid with measles Measles is a sickness that first makes you feel sick, with a fever, a cough, and a runny nose. Then it gives you a rash all over your skin. It is caused by a virus, and you usually catch it by touching a person with measles, or touching something they [...]

An eclipse of the moon. You can see the curved shadow of the Earth. Once people have seen that something happens through observation, sooner or later it will occur to them to ask why it happens. And is there any way to prove that it will happen the same way every time? Sumerians developed advanced math to [...]

History of Electricity – Science of shocks

By |2017-09-05T08:39:33+00:00September 5th, 2017|Science|

A bolt of lightning in the sky Like other inventions, electricity took thousands of years to develop, as scientists all over the world investigated first one idea and then another. Scientists grouped together unseen forces - both magnetism and electricity - and tried to figure out whether these forces were inside the attractor, [...]

What is inertia? Physics – Science

By |2018-05-31T11:49:29+00:00August 18th, 2017|Physics|

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 [...]

Newton’s First Law of Motion – Physics

By |2018-05-31T11:49:24+00:00August 17th, 2017|Islam, 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

By |2018-05-31T11:49:25+00:00August 17th, 2017|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 [...]

Newton’s Second Law of Motion project

By |2018-05-31T11:49:15+00:00August 17th, 2017|History|

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 [...]

What is centrifugal force? Physics definitions

By |2018-05-31T11:49:24+00:00August 16th, 2017|Islam, Physics|

Kids playing tetherball using centrifugal force When something is going straight, it always keeps going straight unless something else stops it or turns it. (The Iranian scientist Ibn Sina figured this out about 1000 AD). If it can't go straight, then it goes as straight as it can. So when you hit a tetherball, it [...]

Ancient philosophy: ethics, fate, and science

By |2018-04-24T11:55:01+00:00August 16th, 2017|Philosophy|

Weighing the souls of the dead Philosophy means the love of wisdom. But what does that mean? It's hard to separate philosophy from religion. And it's also hard to draw a line between philosophy and science and mathematics. All of these are parts of people's search to make order out of nature. They're a way of [...]
