- Why does the universe exist? Everyone has heard theories about how our universe appeared. The most popular theory in the scientific community is Big Bang Theory. However, all the theories answer the question "how", but not "why". There are billions of lifeless planets in the space. Why do all of them exist? What is the purpose of lifeless planets that humans will never reach? The problem here is the "why" question. When we ask "why", we refer to motivation and intentions of a person. The question "why did he do that?" means "what was his motivation to do that?", "what reasons did he have to do that?". However, if we ask a "why" question about an inanimate object, it is a completely different question. "Why did tsunami happen?" actually means "How did tsunami happen?", cause tsunami has no motivation or intentions. When we ask "why", we ask about the process and how it proceeds. So what is the answer to the question "why does the universe exist?". This question simply doesn't make sense. We can ask "how does it exist?", "what processes occur in the universe?", "how has it appeared?", but the universe has no motivation or reasons to exist.
May 20, 2018101 - Why social networks make us unhappy Everybody uses social networks. They become the main communication tool for many people. Social networks allow us to share pictures and videos with our friends, read the news, chat with people all over the world. Isn't it great? Yes, it is, but what pictures and information do we usually post on our personal pages? We post photos from our journeys, restaurant visits, parties. Nobody makes a post about being late on a job, waiting for an hour in a traffic jam, breaking up with a girlfriend. When you read a news feed, you see that everyone is extremely happy and successful. Everyone, except you. Social networks make us think that our life is less interesting and exciting that lives of others. As a result, we start following this strategy and try to post the best moments of our lives to prove everybody that we are as happy as them. For example, a person may go to the party and, even if the party is awful, to post a photo where the person smiles and pretends to have fun. Isn't it absurd?
May 19, 201844 - Do we have freedom of choice? You might think that I am a person who believes in fate, but I'm not. Let's think of it from a science point of view. For example, you see an apple and you want to eat it. Why do you want to do that? Maybe your tongue has cells that react on the apple. Maybe you have some memories from your childhood when your grandparents gave you apples from their kitchen garden. Everything has a reason. Let's think of another thing. If you throw a ball into the air you know for sure that it will fall down. If you know its mass and the start speed, you can calculate the time when it falls down. And now, let's imagine that we can calculate it for all the atoms of some object. It would mean that we could predict its behaviour. Our brain also consists of atoms. So it could be possible to predict a person's action. Some physicists think that our universe is chaotic on the atom level. But can we say that we have a freedom of choice if atoms of our brains behave chaotically?
May 19, 201850 - Will Artificial Intelligence Conquer The World? AI is a very popular topic nowadays. We are all amazed of what big IT companies have achieved over last 20 years. Everyone has seen movies and read books about AI. Will it all end up with "Westworld" scenario? Let's find it out. The computer is a calculation machine. It works with the digital signal that we treat as 0 and 1. The computer already does many things better than humans. It can save a huge amount of numbers, text (that is also converted to numbers) and it does it very fast. However, all its operations are just hardcoded mathematical algorithms. The computer doesn't "understand" what it does. So how does the voice and image recognition work? Well, it is not easy to describe in a few words, but the main idea that there is a mathematical model behind that. It is a complex function with many parameters that are adjusted by the set of training data. Even though the computer can recognize your speech and transform it into the text, it doesn't have the understanding of it. Enough technical details :). So will AI conquer the world? Yes, if we ask it to do that. If we write a software with instructions to do that. The computer doesn't have a feeling or wishes. We need to be afraid humans who will use technologies to take advantages of us.
