The Reality Check Episode 16

Mortality/Risk+Evidence/Falsifiability+Coriolis Effect/Toilets

The Coriolis Effect
Part 1:
Mortality rates are consistent at 100%, because everyone dies. What do people die from? In Canada 2001: Cardiovascular diseases at 33%, cancer at 29%, respiratory at 8%, and suicide is around 1.9 percent. Nowadays we are better at preventing these causes, but we are still worried about getting attacked to shot by someone we don't know. The percentage of that even happening is less than a quarter of percent. Why do we worry about such things when other things are much more likely to kill us? There are two reasons, our brain are structures to remember suddenly painful events than potential gradual events. The image of someone getting killed is memorable, we don't really have a visual eating unhealthy food for a long time. Second, the media is again messing with our heads, it's all they have in the news these days. The most brutal events are always on the front page, so it gives us an impression. One other thing might be also that the diseases are caused by ourselves; we have control over it. We can choose to eat junk food or not, but getting attacked by someone isn't a choice, sometimes it just happens. That probably increases the fear of getting attacked. 

Part 2:
As if we need more evidence for evolution Part 2. Darwin's theory is falsifiable, that's why it's real science. If a theory is not falsifiable, then it's not science, it's just crap. Darwin said that all living things evolve, and he gave fossil evidence on how it happens. But there weren't enough fossils that time to convince people that this is true, however, nowadays, we do have enough evidence to prove that Darwin's theory is correct. For example, we found in a desert fossils of creatures with skeletal features just like whales, except with legs. It's incredible how creatures evolved from the water onto land, and then back to water. Another thing is that we never found any recent creatures in the ancient times. 

"While evolution can't explain anything, intelligence design can't explain anything" 


Science Myth of the Week: The Coriolis Effect
Many people claim that the Coriolis Effect effects the spinning direction of the toilet water and drain. So, what they mean is that when you are in the Southern hemisphere, the water would spin in opposite direction than it does in the Northern hemisphere. The Coriolis Effect is real, but it does NOT effect how the water spins. It would only effect a large body of water, and so the amount of water most of us see isn't big enough to have the Coriolis Effect.
