5 movie scientific myths

Below are 5 scientific myths found in the movie the Martian.

False
1.       Going to Mars
a.       Even though there is some knowledge about Mars, there has not been a person who has actually gone
2.       Growing food on Mars
a.       In the movie, Mark (the main character) tries to grow food using Mars’ soil, which is not something that has been done
3.        Duct tape
a.       When the door of the base broke, he used duct tape to put it back together, which would not work in real life because the oxygen would come out of it.
4.       Space suit
a.       As of now, there is not a suit that can effectively protect someone in the environment of Mars.
5.       Windstorm
a.       When the astronauts were about to leave, there was a storm. From the knowledge we have on Mars, storms to that level cannot form. 

True

  1. Planting vegetables

    1. As of now, there are crops that have been planted, even though it's different from the way it's shown in the movie, the idea is the same.

  2. Water filtering

    1. The way Mark filters his pee and other liquids is similar to the way actual  astronauts do it

  3. Oxygen tanks

    1. Since Mars does not have oxygen, humans need oxygen tanks to be able to breath

  4. Tornado

    1. Even though the atmosphere is too thin to form the dust storm, it it possible for a tornado to form. In 2005, NASA got a video of one

  5. Travel time

    1. In the movie, Mark had to plan on not being able to be rescued for months. In reality it'll take 8-9 months to get to Mars, making this accurate

From sea to land- Tetrapods

From what we discussed in lecture and what I found online, organism that evolved to walk in land are called tetrapods.


The organisms that tetrapods evolved from are obe-finned fishes. After millions of years, animals became more adapt to walk on land. For example, organism developed more adapt lungs, and eventually they gained the capacity to walk in two feet like humans do now.
