Facts about rain

 Even though we all know what rain looks like and why it occurs, there are still plenty of facts about it that many of us haven’t heard about. First of all, when we imagine rain drops, they are usually tear shaped, and it's not how they really look like. Rain drops have spherical shape and the bigger the drop, the flatter they become, so before it starts to rain we can already recognise how big the shower will be after studying a single drop shape on the ground. We can also recognise a heavy shower by the speed of drops hitting the ground, because the weight of huge drops make them fall really fast. Also many places that we associate with rainy weather are not as wet in statistics and it’s because it might be raining there every single day, but most of the time those are light drizzles. It’s all about the number of millimeters of rain per year that counts and not the number of rainy days. Also, the rainfall in millimeters can differ for every single meter of the ground, so the measure is always the average. In my opinion, those aren’t any surprising facts, but it still makes us think about an everyday event in a different, more curious way.

  1. Isn't a rain drop a bit like a balloon that changes its shape depending on external pressure?

Why are conspiracy theories so popular?

Conspiracy theories are popular mainly because they give us the thrill and emotions, and we also don’t like to accept everything we have been told by the government. We enjoy stuff that have deeper meanings. It makes our life interesting and it gives us a space to overthink even obvious stuff. So believing in even mindless conspiracy theories gives us the sensation. Also, another important reason is that we don't like being told what to believe in. We don’t always want to trust everything around us so easily, so we root for another solutions and beliefs, which lead us to creating those theories.

Problems of anime industry- part 2

The biggest issue with anime industry is that animators don’t get paid enough. Animating is extremely time consuming and in Japan it is a very unbeneficial job. According to the  Japanese Animation Creators Association , a Japanese animator in their 20s earns on average ¥1.1 million (which is about $10,000) per year, while the poverty line in Japan is earning  ¥2.2 million per year. So the only way the animators make ends meet is working even more, which leads to another issue of animators- being overworked. There are plenty of cases where those poor workers fall asleep at their desks, have their health declined and are hospitalized- all because of exhausion. It also happens, that animators even commit suicide due to such an unpleasant job. Some time ago, even a popular studio Madhouse has violated lobor code, because employees were working 400 hours per month, so the problem is more complex than you could think. In my opinion, this whole topic is heartbreaking and animat...

Secondhand christmas gifts

  Christmas is always associated with spending time with your loved ones, but lately it looks like it's a holiday of massive consumption. We all love receiving gifts, but research shows that we appreciate them more when it's something sentimental and has a history behind it. That's why we should start buying our christmas gifts secondhand. What makes an item meaningful is not its price, but its past, that we can fantisize about. So getting an old item can be good for the imagination, as well as it makes us take better care of our current belongings. It creates an attachment to our stuff, so when they get old, we're more likely to give them a new life, than just throw them out. In my opinion, this idea is just brilliant. I, myself am a big oponnent of mindless consumption during black fridays and christmas. I think nowadays, a lot of us are addicted to shopping and most of our purchases are things, that we don't actually need, but we just like the feeling of having b...
