Lay v. Lie

These are a bit tricky, there is no easy way to remember lay vs. lie. You are probably going to have to memorize it:

Present Tense          Past Tense        Past Participle

lay                                laid                     laid

lie                                 lay                       lain                 

Let’s take a closer look at this. For lay, an object must be involved. For example, a police officer would tell a criminal to lay their gun down. For lie, you do not need an object. In this case you can say you lie down. Maybe you lie down on the couch or bed or on the grass, but you don’t have to put down any of those.

You will notice that lay is the past tense of lie. Lain is the past participle of lie.

Laid is the past tense and past participle of lay.

Good luck remembering lay vs. lie!

Scientific Method

There are several steps to the scientific method.

First, ask a question. Why did this apple fall from the tree?

Second, do background research. Lots of things fall, not just apples from trees.

Third, create a hypothesis. There must be some sort of force that not only makes apples fall from trees, but that also keeps everything from falling off this planet.

Fourth, test this hypothesis with an experiment. Lets send some apples up in a space shuttle and try to get them to fall from the ceiling to the floor of the space shuttle. The apple just floats. There is a force that pulls things towards the Earth! Let’s call it gravity!

Fifth, analyze the results. Our hypothesis is correct. Let’s do more experiments with gravity! If a feather and a rock are pushed off the Empire State Building, do they reach the ground at the same time?

Last, share (which usually means publish) your results. Let’s share what we learned with the world!

Why is this important?

Because if you are reading scientific articles, often they will follow this exact same formula.

The article usually begins with a general question that has intrigued the author. The author will then go over what is already known. They will go over background information and do a literature review, discussing what related experiments have already been done. Then the author will present their hypothesis, which is both their main point and their guess as to how things work. At this point the author will usually describe their experiment in great detail, and then they will analyze the data they gathered. They will discuss how well the results of the experiment match their hypothesis. If there is a match they will often discuss possible future experiments that can expand on their findings. If their is not a match or their is a partial match they will discuss why that is and suggest a new hypothesis to consider.

Quadratic Formula

Quick review first. A quadratic equation in algebra is one which follows the following pattern:

ax² + bx + c = 0

So an actual equation would look something like this:

2x² + 3x + (-5) = 0

This equation could be solved in several ways. One of the primary ways you will be asked to solve it is with what is called the quadratic formula:

x = -b ± √b² – 4ac/2a

You will have noticed an unusual symbol: ±. It means both plus and minus. So the whole thing means:

x = -b + √b² – 4ac/2a and x = -b – √b² – 4ac/2a

So using the numbers we plugged into the quadratic equation, let’s now put them in the quadratic formula.

x = -(3) ± √(3)² -4(2)(-5)/2(2)

x = -(3) ± √9 – 4(2)(-5)/2(2)

x = -(3) ± √9 – (-40)/4

x = -(3) ± √49/4

x = -(3) ± 7/4

x = -(3) + 7/4 and x = -(3) – 7/4

x = -(12/4) + 7/4 and x = -(12/4) – 7/4

x = -5/4 and x = -19/4
