THE GREAT MUSLIM WOMEN OF ALL TIME  This post, the first of several on the topic, intends to highlight the various contributions of Muslim women throughout medieval and early modern history. While many people may be familiar with the accomplishments of contemporary Muslim women (whether heads of state, scholars or activists), the fact that women also played a pivotal role in the pre-modern Muslim world as intellectuals, poets, mystics, rulers and warriors tends to be less

All you wished you knew about Cholesterol... CSS topic of General Science.

Image
Cholesterol is a waxy, fat-like compound that belongs to a class of molecules called  steroids . It's found in many foods, in your bloodstream and in all your body's cells. If you had a handful of cholesterol, it might feel like a soft, melted candle. Cholesterol is essential for: Formation and maintenance of cell membranes (helps the cell to resist changes in temperature and protects and insulates nerve fibers) Formation of sex hormones  (progesterone, testosterone, estradiol, cortisol) Production of bile salts, which help to digest food Conversion into vitamin D in the skin when exposed to sunlight.

Semiconductors: Technological advancement that changed the world.

Image
Semiconductors  materials such as silicon (Si), germanium (Ge) and gallium arsenide (GaAs), have electrical properties somewhere in the middle, between those of a “conductor” and an “insulator”. They are not good conductors nor good insulators (hence their name “semi”-conductors). They have very few “free electrons” because their atoms are closely grouped together in a crystalline pattern called a “crystal lattice”. by controlling the amount of impurities added to this intrinsic semiconductor material it is possible to control its conductivity.  Various impurities called donors or acceptors can be added to this intrinsic material to produce free electrons or holes respectively. This process of adding donor or acceptor atoms to semiconductor atoms  is called  Doping . The as the doped silicon is no longer pure, these donor and acceptor atoms are collectively referred to as “impurities”, and by doping these silicon material with a sufficient number of im...

What make Sun shine and produce heat?

Image
The sun has three main parts: the core, the radiative zone surrounding the core, and the convective zone around that. The core of the sun makes up the inner 25 percent. The radiative zone makes up 45 percent of the sun’s radius, and the convective zone makes up 30 percent of it. The gravity of the sun pulls its mass inward, creating a lot of pressure. This pressure forces atoms of hydrogen to fuse together in nuclear reactions, like nuclear bombs that people build. The energy gives off different kinds of light, like infrared light, ultraviolet light and visible light. Microwaves, radio waves and X-rays also come from the sun. The sun also gives off energized particles that make up solar wind. The energy from solar wind warms the Earth and influences the weather. Thanks to the Earth’s atmosphere, most of the sun’s radiation and solar winds doesn’t harm us HOW SUN WORKS? . source: http://discoverykids.com/articles/how-does-the-sun-provide-heat-and-light/ h...

How Artificial rain formed? learn about Cloud seeding

Image
What's common to boiling water, artificial rain and the Mentos-Diet Coke reaction? It's nucleation! Let's see what that means. So what is nucleation? How does rain happen in nature? As wind passes over the sea, it collects evaporating water as very, very tiny drops. As the wind rises high in the air, temperatures become very cold, causing some of these drops to merge. This bigger drop attracts more drops of water, and so on and on. This process is called nucleation. When the water drops become about 0.1 mm thick, they cannot float in the air anymore. They then fall to the ground as rain. HOW TO MAKE ARTIFICIAL RAIN IN URDU?     Artificial rain Sometimes it does not get cold enough in the cloud for nucleation to occur. But if we want the cloud to rain, we have to create places where nucleation can occur. This is done by a method called cloud seeding. Tiny particles of silver iodide are sprayed on a cloud from an aeroplane. Sometimes, solid carbon d...

Why is water the "universal solvent"?

Image
Water is known as theuniversal solvent. Here is an explanation of why water is called the universal solvent and what properties make it good at dissolving other substances. Answer:  Water is called the  universal solvent  because more substances dissolve in water than in any other chemical. This has to do with the polarity of each water molecule. The hydrogen side of each water (H 2 O) molecule carries a slight positive electric charge, while the oxygen side carries a slight negative electric charge. This helps water dissociate ionic compounds into their positive and negative ions. The positive part of an ionic compound is attracted to the oxygen side of water while the negative portion of the compound is attracted to the hydrogen side of water. Despite its name as the "universal solvent" there are many compounds water won't dissolve or won't dissolve well. If the attraction is high between the opposite-charged ions in a compound, then the solubility...

difference between CLIMATE and WEATHER?

Image
The difference between weather and climate is a measure of time. Weather is what conditions of the atmosphere are over a short period of time, and climate is how the atmosphere "behaves" over relatively long periods of time. Weather is what you see outside on any particular day. So, for example, it may be  75° degrees  and sunny or it could be  20° degrees  with heavy snow. That’s the weather. Climate is the average of that weather. For example, you can expect snow in the Northeast in January or for it to be hot and humid in the Southeast in July. This is climate. The climate record also includes extreme values such as record high temperatures or record amounts of rainfall. If you’ve ever heard your local weather person say “today we hit a record high for this day,” she is talking about climate records. When scientists talk about climate, they're looking at averages of precipitation, temperature, humidity, sunshine, wind velocity, phenomena such as fog, f...

HOW MUCH YOU KNOW ABOUT SUN? learn some facts and how it produce heat and much more

Image
The sun is a big ball of hot gases. The gases are converted into energy in the sun's core. The energy moves outward through the interior layers, into the sun's atmosphere, and is released into the solar system as heat and light. Most of the gas — about 72 percent — is hydrogen. Nuclear fusion converts hydrogen into other elements. The sun is also composed of about 26 percent helium and trace amounts of other elements — oxygen, carbon, neon, nitrogen, magnesium, iron and silicon. These elements are created in the sun's core, which makes up 25 percent of the sun. Gravitational forces create tremendous pressure and temperatures in the core. The temperature of the sun in this layer is about 27 million degrees F (15 million degrees C). Hydrogen atoms are compressed and fuse together, creating helium and a lot of energy. This process is called nuclear fusion. WHAT IS SUN video explains everything. Abundance of elements Astronomers who have studied the...

HOW ARE MOUNTAINS FORMED? discover the science of continental drift

Image
How are mountains formed? Mountains are formed by slow but gigantic movements of the earth's crust (the outer layer of the Earth). The Earth's crust is made up of 6 huge slabs called plates, which fit together like a jigsaw puzzle. When two slabs of the earth's crust smash into each other the land can be pushed upwards, forming mountains. Many of the greatest mountain ranges of the world have formed because of enormous collisions between continents. Watch HOW MOUNTAINS ARE FORMED video made easy?  Mountains form in different ways Sometimes the crust has folded and buckled, sometimes it breaks into huge blocks. In both cases, great areas of land are lifted upwards to form mountains. Other mountains are formed by the earth's crust rising into a dome, or by volcanic activity when the crust cracks open. What different types of Mountains are there? There are five basic kinds of mountains: Fold Mountains (Folded Mountains) Fault-block Mountain...
