Today we're going to take a look at the fundamentals of any scientific experiments - precautions.
Precautions are necessary to obtain the most consistent and accurate result in whatever scientific experiment you're doing, and therefore it would be handy to prepare a list of them before you even begin the experiment.
That said, the precautions below are fundamentals and must be observed at all time. By that I mean that they are general enough to be used in any experiments. It's a rough list, but I suppose it's passable.
Precautions:
1. Close all windows to simulate a closed environment.
2. Switch off all fans to reduce air movement
3. All instruments are checked for parallax errors before the experiment
4. Care is taken not to disturb the instruments while the experiment is ongoing
5. All readings are taken at eye level to avoid parallax errors
6. Multiple readings are taken and the mean is used to obtain a more accurate value.
That said, precautions vary according to the type of experiment. Exercise logic combined with a little scientific knowledge and you'll do fine.
The more precautions you have, the more likely your result will be accurate.

A rainbow.
While I was strolling down the exhibits of the Ikeda Photography Exhibition, something caught my eye.
We weren't allowed to bring cameras, so no, no pictures to show here.
It was a picture of a rainbow. A photograph of a rainbow.
The tour guide explained to us that the purpose of the photograph was to celebrate the magnificence of the rainbow. The rainbow is a reflection of human life force. Forever Vibrant.
My words will do the rainbow no justice. I lack the skills to share with you the grandeur of the rainbow. Perhaps this excerpt here will... light the way.
Faust, Part II, Act II
But see how, rising from the turbulence,
the rainbow forms its changing-unchanged arch
of Human striving it's a perfect symbol
ponder this well to understand more clearly
that what we have as life is a many-hued reflection.
I had my breath taken away.

Laws of Procrastination
You've all probably heard of Newton's Laws of Motion. Now, I shall present to you-
The First Law of Procrastination:
A person who is at rest will remain at rest, and a person who is studying will remain studying.
A person will only 'accelerate' when there is a net or unbalanced force acting upon it, changing the direction, the speed, or ...both the direction and speed.
The Second Law of Procrastination:
A student of laziness [M] subject to a net determination [F] undergoes an improvement [a] that has the same direction as the determination and a magnitude that is directly proportional to the determination and inversely proportional to the laziness.
i.e. : F=ma
The Third Law of Procrastination:
For every action towards good results, there is an equal and opposite distraction. These mutual forces are equal, opposite and collinear.
