Computer Aided Design & The 118 Elements
by Florin FODOR
The Periodic Table of Elements contains 118 elements we currently have knowledge about. 92 of them occur naturally on Earth , all the rest are artificially made. Most of the 118 elements at normal temperature (20°C) and pressure (1atm), occur in solid state, a few are gases and just 2 are liquid (mercury Hg and... Continue Reading →
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. Like Tea, making a good... Continue Reading →
I am sure most people will say, what's so much of science to make a good tea? Should not be a big deal, simply take a bag of tea or tea leafs and put it in a cup with boiled water, then add some sweetener and done. The tea is ready. Right? Well... things are... Continue Reading →
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 →
There is no better example to start a topic about cooling fluids than aircrafts. We all have today the option to travel by plane anytime and anywhere in the world. When you do that, of course maybe the only inconvenient you might have is that you must sit and keep the seat belt tighten during... Continue Reading →
Until not long time ago, the most common ways of entertainment were reading books or listening to music. Then by mid of 20th century television started to gain in popularity and watching a movie at home has become very much a new common habit to enjoy our leisure time. However the first TV sets were...

There are not many things which can be taken as defining elements of the human history and civilization, but there are few. 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 →
3D Printing is a relatively new technology which has gained a lot of attention lately. More and more application using this new tech-development have been already successfully implemented in various industries. Now it is going to be used on building roads too. A new research has been quite recently done by a group of scientists... Continue Reading →
