Magnets

Science > Physics > Magnetism > Magnets About 600 to 800 BC the people living in Magnesia in Asia Minor found a stone (an ore of iron Magnetite Fe2O3) which was capable of attracting iron pieces towards it. They called this stone as magnetite. During the course of time, the name changed to a magnet. […]

The Blood

Science > Biology > Human Anatomy and Physiology > Cardiovascular System > The blood, an Overview In the Cardiovascular system, the ‘‘heart’’ (cardi) pumps the blood in a ‘‘little circle’’ (circul), which travels through ‘‘little vessels’’ (vascul). In human, the transportation is done through blood circulatory system and lymphatic system. Thus two fluids move through […]
