From @umit06 ➪ [Ses Nedir, Etkileri Nelerdir?](https://steemit.com/tr/@umit06/ses-nedir-etkileri-nelerdir)

> Sound is one of the phenomena that we have never thought about but which everyone should know. So much so that it affects us in many different ways. Even when we close our eyes or even sleep, our ears are on duty. Our ear is also a bad example for us by working 24/7. Sleeping in front of the television: When you fall asleep, the sounds coming from television begin to work your consciousness and direct your dream.

From @merveakbulut ➪ [HAYALİMDEKİ MATEMATİK ÖĞRETİMİ](https://steemit.com/tr/@merveakbulut/hayalimdeki-matematik-oegretimi)

> One of the greatest pieces of math teaching in my dream is to create a classroom environment where students are constantly communicating and feeling safe. Students who are able to express their own thoughts without fear are freed in a personal sense and at the same time they will facilitate learning with a spacious brain. To achieve this, a class system can be established in which they can face-face and perform group activities, and friends can easily see new ideas.

From @bayeco06 ➪ [Opportunity Cost and Economic Specialization | Fırsat Maliyeti ve Uzmanlaşma](https://steemit.com/economy/@bayeco06/opportunity-cost-and-economic-specialization)

>Opportunity cost is the amount of goods and / or profits to be waived, disclaimed by another good to increase the production of any good by one unit. In other words, it is the second best alternative that has to be abandoned while making an economic choice.
