The Importance of the Lab Notebook


Last Week, I mentioned I would do a blog on the importance of keeping a good lab notebook this week. So this is me fulfilling that statement. Think of this as a weird part two to last weeks blog; kind of like “Let's Kill Hitler” to “A Good Man Goes to War”.
The lab notebook has it's sticky little fingers in every single aspect of your modern, western life. The buildings which surround you and in which you live and frequent. The clothing which you wear. The food you eat. The computer you are reading this on. The internet networks that allow you to access this website. Thumb drives. The military. Medical science. The PA systems of poetry readings and stage performances such as plays. Batteries. Vehicles. Weapons. Drugs, legal as well as illegal. Television. Every aspect of your life, no matter how minor and minute or how big and grand it is, it depends on the lab notebook.
Here, I will provide a few examples. The first is for those of you who are hip with your own respective nations military. Your military depends on weapons such as various guns, various bombs, various defense systems, various vehicles, various communications systems. Everything on the field of battle depends on scientists working in the background making damn sure those items work properly frequently enough for the soldiers to do what they're advertised to do; stay alive while killing other people. This requires the lab notebook, because if one scientist alone works on one single project, that scientist will make a few mistakes. And those mistakes will be perpetuated through all of the experiments that scientist performs on that project. Therefore, that scientist has to transfer further study on the project to other scientists. This requires explicit notes on what was done on what aspects under what conditions as well as the observations taken from these experiments and the conclusions taken from them. This is exactly what the lab notebook is. Detailed procedures, detailed observations. Hypothetical preliminary explanations.
For those of you who care about the capitalistic machine, there is a huge fiscal reason for the lab notebook. If there is a scientist working on a new breed of, say, computer, if that scientist is not using a lab notebook – or keeping a piss poor lab notebook, or throws away their lab notebook like Zhiwen Zhang of last weeks blog did – then the double checks and triple checks will be that scientist will basically be saying “you're just going to have to trust my memory.” That doesn't flow in science. If that scientist goes to the head of the department and uses that phrase, that would not fly. The scientists and head of the department will have essentially the same reaction; “Show me the lab notebook. Show me your work.” So said scientist will have to run the experiment again and keep good notebooks to conduct better research. Running these experiments again under bad lab notebook keeping procedures wastes man-hours. It wastes materials. Both of these wastes money. This all to make the products you buy usable out of the cheapest products possible.
If you are of the mind-set of scientific accuracy (as I am), taking the word of another scientist without the lab notebook is like a Christian taking the word of a Muslim, or an atheist taking the word of a Christian, or liberals and conservatives taking each others words for it. It just does not fly. In order for me to double check your work, I need to run your experiment to confirm it for myself. The same holds true the other way around. In order for you to double check my work, you need to run the experiment I have run. In either direction, this depends on the lab notebook. This is the explicit notes of precisely what you did and how much material you used and the times and observations. The explicit details in the lab notebooks help us as humans and as scientists keep each other scientifically honest, but more importantly, to severely reduce mistakes and errors.
These are just a few examples of why the lab notebook is so important in society. I am sure that if you contemplate it hard enough, you can think of more examples of why the lab notebook is important to you.


Take that as you will.

Basic Statistics Lecture #3: Normal, Binomial, and Poisson Distributions

As I have mentioned last time , the uniform continuous distribution is not the only form of continuous distribution in statistics.  As promised, here are the three most common continuous distribution types.  As a side note, all sampling distributions are relative to the algebraic mean. Normal Distribution: I think most people are familiar with the concept of a normal distribution.  If you've ever seen a bell curve, you've seen the normal distribution.  If you've begun from the first lecture of this lecture series, you've also seen the normal distribution. This type of distribution is where the data points follow a continuous curve, is non-uniform, has a mean (algebraic average) equal to the median (the exact middle value), falls from highest probability at the mean to (for all practical purposes) zero as the x-values approach $\pm \infty$, and therefor has equal number of data points to the left and to the right of the mean, and has the domain of $(\pm \i

Confidence Interval: Basic Statistics Lecture Series Lecture #11

You'll remember last time , I covered hypothesis testing of proportions and the time before that , hypothesis testing of a sample with a mean and standard deviation.  This time, I'll cover the concept of confidence intervals. Confidence intervals are of the form μ 1-α ∈ (a, b) 1-α , where a and b are two numbers such that a<b, α is the significance level as covered in hypothesis testing, and μ is the actual population mean (not the sample mean). This is a the statement of there being a [(1-α)*100]% probability that the true population mean will be somewhere between a and b.  The obvious question is "How do we find a and b?".  Here, I will describe the process. Step 1. Find the Fundamental Statistics The first thing we need to find the fundamental statistics , the mean, standard deviation, and the sample size.  The sample mean is typically referred to as the point estimate by most statistics text books.  This is because the point estimate of the populati

Basic Statistics Lecture #5: Baye's Theorem

As promised last time , I am going to cover Baye's Theorem. If Tree diagram is the common name for Bayes Theorem.  Recall that conditional probability is given by $P(A \mid B) = \frac{P(A \wedge B)}{P(B)}$.   For tree diagrams, let's say that we have events A, B 1 , B 2 , B 3 , … (the reason we have multiple B's is because they all are within the same family of events) such that the events in the family of B are mutually exclusive and the sum of the probabilities of the events in the family of B are equal to 1. Then we have $$P(B_i \mid A)= \frac{P(B_i)*P(A \mid B_i)}{\sum_{m=1}^{n}[P(B_m)*P(A \mid B_m)]}$$  What this means is reliant on the tree diagram. If we are only looking at the sub-items of A, this is what the tree diagram would look like. If J has a probability of 100%, and P(C) and P(D) are not 0, then when we are trying to find the probability of any of the B's being true given that A is true, we have to set the probability of A to be the entir
