Preface:
Hello everybody and welcome to the 3rd project that I’m gonna make this year.
This project I watched 10 video’s and from 5 video’s I’m gonna answer the questions and you can see everything I did below.
By the other 5 video’s I made by myself 10 questions including the answers.
I also have listened to 5 podcasts from BBC and I made 10 questions (including answers) about the podcasts.
This is what I have done for project 3. You can find everything during this project.
Have fun reading!

5 video’s with questions I’m gonna answer:

Questions + answers:
 Explain why it was important for sailors to measure the distance between the horizon and a celestial body. How did it help them determine their position in the ocean?
Answer: Yes, because in this way they could determine where they were and compared to where they were at that time. In this way they could always find the way back home.
 Who invented the first device that could measure the distance between the sun and the horizon during the day?
Answer: John Bird, he was an instrument maker. He made an instrument named sextents. This device could measure the distance between and such a horizon so that sailors knew where they were.
 Obviously, we no longer use sextants and clocks to navigate the sea. Name three inventions that have carried us past the use of logarithms.
Answer: Through these instruments we have been able to make cards that give a global overview of the seas. We also have a compass that we can see which direction we have to sail. If you want to know very accurately where you are a satellite navigation, which measures where you are and where you should go and so a route is given.
 According to Christoph, three inventions made modern navigation possible. Which is not one of those inventions:
A: Sextants

 How long did John Napier toil in his castle to invent logarithms?
Answer: John Napier find a way to guide ships with mathematics. He sat 20 years in a castle and together with other mathematician he found the solution: logarithms.
So after 20 years.
 In simplest form, a logarithm is used to answer this question: How many of one number do we multiply to get another number? Why don’t we just use our multiplication tables? Why are logarithms necessary?
Answer: The logarithm has been devised around 1600 to easily multiply and share large numbers. With the help of logarithms, exponents can be used, which are much smaller than the numbers itself.
 Approximately 400 years ago, ships attempted to maintain an accurate record of direction, time, and distance. Sailors based their directions on the port they left. This process is called…
Answer: dead reckoning.
 What was different about John Harrison’s clock (invented in 1761)?
Answer: It could keep accurate time at sea.

Questions + answers:
 The Reynolds number quantifies the ratio between forces due to _ and .

 What is the energy cascade?
Answer: The transfer of energy from large to small eddies in the flow.
 “ is an example of a laminar flow, while __ is an example of a turbulent one.”

 What of the following can we say about turbulence?
Answer: It is always random.
 Turbulence happens all around us and its effects can potentially influence entire industries. What are some things that can improve with a better understanding or Turbulence?
Answer: At large heights without mountains that brakes the wind, this effect is felt even more. If the wind is turned from speed and direction, the molecules change around the wing quickly. Sometimes there are more molecules that give more elevator, and other times fewer molecules that give a little less lift; And they are these differences that take care of turbulence.
 What do you think are some things that make turbulence more prone to happen?
Answer: Turbulence is not dangerous but it can still be uncomfortable and so it is useful to check the weather conditions before flying and there is nothing else you can do about it. (This is my opinion).
 Clear air means less chance of turbulence and more stable air molecules.
