Today, in the 15th ScienceBeer, Artem was our Science Brewer. Artem is a Professor in TU-Dresden and works on Wirtschaftliche Aspekte der ökologischen Raumentwicklung. Artem first defined what is economy? Then he explained to us how economy is affected by other factors. Then we learned what happens when big economies meet smaller ones. Now we know what may happen as a result of having a mega city next to smaller cities; what can happen when we skip some intermediate levels of industrialization and more importantly why all of these are happening. Artem also told us what are the common practices to stop the negative effects and why they may or may not work in certain situations. Thank you Artem.
