10 Questions Scientists Don’t Have Answers To

A placebo is something that doesn’t have any evident therapeutic effects (like for example, water). The phenomenon when people start to feel better after taking a pseudo-medication is called the placebo effect.

There are several theories about how it works. Some people believe that human consciousness does something so that the body heals because the patient believes the treatment will help. Others think that even a conversation with a doctor is enough to feel better. Others say that placebos don’t have any effect at all. Either way, the placebo effect is a question we don’t have an answer to.

3. How do computers understand what people say?

Our language is a complex structure that depends on a lot of different factors. When it comes to artificial intelligence, interpretation is very important. For example, the phrase, “eat this bowl of soup” people understand as a suggestion to eat soup. And the bowl, in this case, is the amount of soup. A computer understands these words literally — as an order to eat a bowl.

Today, a computer is nothing more than a device that can’t understand context as well as a human can. And this means that at this moment, it’s impossible to make a computer understand 100% of human speech.

4. Scientific theories are refuted with time, so is it possible that we don’t really know anything at the moment?
