Through The Senses

This blog is meant to transmit the joy of exploring the world in aesthetic and mathematical terms. Most of the posts will be presented from my point of view, so it might be very subjective. Through the blog, I hope people will appreciate science more and feel a sense of joy in questioning things and exploring the answers for them.

Let's begin with Galilean transformations

Before that, let's begin with the basic question. What is science? The word science is clouded with so many definitions, politics, debates that it can take a form very distinctive in everyone's head. But let's be loose in our definition of science and say that Science is nothing but deductions and theories established on consistent experimental observations.

So, why Science? As a matter of fact, we are all scientists. We go about our daily lives trying to make sense of the various things and people we encounter. We like exploring new things, appreciating new ideas and making more sense of the world. Surely, different people have different opinions at times about the same topic. This is where we need to strengthen our opinion by providing evidence that is consistent with our opinion.

But Science is primarily the joy of exploring the world. As you explore the world, you question why things behave in a certain way and you try to answer why they behave that way.

Let's begin with Galilean transformations. An activity that you can try is to just throw an object in the air right above you and catch it when it falls back down again. So right now, when you're sitting in your chair and doing it, you would (obviously?) catch it back again.

But let's repeat the same activity in different situations: 1) Say when you're in a moving bus, 2) when you're in a merry go round, 3) when you're on a swing, 4) when you're in an elevator.

While doing these experiments, you may wonder whether I meant "this" or I meant "something else". And in that case, you try both of them. And you may have many doubts about what I mean. Remember that no question is bad in science. I'd be happy to answer the question if I have the answer.
