When we travel by plane the cruising altitude is always above the clouds (at around 12.000 meters high). If your flight is on a full sunny day and you look downwards though the window at that height you either see the ground below or a white blanket of clouds. But that will quickly becomes boring,...

After, Water and Tea, the 3rd one most consumed refreshment drink must be the COFFEE. At some point I am tempted to put coffee in the same position with tea as both being the 2nd most consumed drinks on the planet, but I guess Tea better deserves the 2nd place.

Air-conditioning systems are essentially refrigerators for air. In your car, for instance, the air-conditioning system passes the cabin air over copper tubes containing refrigerant, thus cooling the air. Cool air can’t maintain a high concentration of water, which is why water droplets form on air conditioners (this is also why clouds form as air rises... Continue Reading →

Except the first 6 metals used by humans namely Copper (Cu), Gold (Au), Silver (Ag), Iron (Fe), Tin (Sn) and Lead (Pb), and water (H2O) which is the most abundant and consumed liquid...

From the first objects ever created by man we always needed to put parts in a functional assembly. Nowadays, our technology is already advanced and the objects we create are almost entirely made of different parts put together in a stiff and functional product. There are multiple ways we can do this.In case of plastic... Continue Reading →
