Each one of us knows that when objects are heated up enough, they start to glow. First in red light, then in orange and yellow hues as they get hotter and brighter. Very hot objects shine white, which is why so very high-temperature bodies are described as "white hot" (such as the Sun, our closest star). A metal nail, for instance, starts to give off a delicate red glow once we heat it above 500 degrees C. But as we will discover in this class, it is already "glowing" while still somewhat cooler, though we ordinarily cannot see it. Such "light" is actually being given off by every object, and we ourselves are walking lightbulbs. During this physics lab class, students have a chance to actually see this invisible radiation using thermal imaging cameras. The world viewed through such a camera offers a new perspective on the thermal processes going on around us.
The classes are conducted only in Polish.
