Uncertain Summers

Tomorrow, I will be seeing the professor who works on nanoparticles. We will be going over schedules and projects. Definitely interesting.
Now I'm waiting to hear back about a job I applied for. If they like my application, I get to be an assistant teacher at a child care center. Otherwise I'm working at Target or Hannaford or one of those large shopping stores.
It is all in God's hands.

Do you know what nanoparticles are? They are tiny pieces of some kind of metal like gold or silver. They are a little larger than molecules.
I hope to do some research with nanoparticles this summer. They are very interesting.

Suppy and Demand

This is a picture of supply and demand curves. Supply and demand are two terms talked about in economics a great deal.

"Demand" refers to how much of a product do people want to buy. As you can see, the horizontal axis (the line with "quantity" under it) tells how much of some product people want to buy. The vertical axis (the line with "price" above it) tells what the price of the product is.
If the price is very high, people buy less of the product, but if it is cheap, people buy lots of it.

"Supply" refers to how much of a product the people selling it want to make. When the price of some product is high, people selling want to sell as much as they can of it, so there is a lot of the product supplied. But if the price is cheap, people do not want to sell that product, so the there is less supply of the product.

On the graph, there is a place where the two curves meet. That is called equilibrium. It is the price of the product where the sellers want to sell the same amount of the product as the buyers want to buy. It is generally the best price for the product.

I should change the name of my blog. Instead of "The Young Thinker", it should be "The Non-Thinker" because most of my posts lately have been ones that required very little of my brain to be used, maybe .001% of it or something like that.
Anyway, I wish I could change that, but it's been rather difficult and my brain has been tired every time I actually get on to post something.

Today I would like to talk about the differences between compressible and incompressible flow. In case you are wondering, flow refers to the movement to some sort of fluid (water, gas, air, etc...) around some object.
There are a number of things one can talk about when discussing flows. There is the velocity of the flow and the pressure of the flow and the density of the flow, and so on. But each of those things I just mentioned change depending on where you are in the flow. So we have a bunch of equations to help us figure out what some of those things are in the place we are looking at.
Now compressible flow is a flow that the density changes from point to point. Density, by the way the the amount of mass of object or fluid that has a particular volume or basically how much stuff is in a space. So that is compressible flow.
Incompressible flow does not exist really. We just pretend it does. In this kind of flow, we say the density does not change from point to point. We pretend that slow moving flows are incompressible because we can use some really nice simple equations to find things then. They are fun equations and much easier to use than those for compressible flow.


Finally, all classes are over. Just finals left.

I am so happy!
God has been so good to me these past two semesters. It has been amazing.
To Him be all glory!
