Algae and Forensics

If you watch a lot of crime shows, you may have seen algae being used to help solve a crime. In Dexter, the algae on the victims was used to determine the port they came from, which led them to Dexter. Or Hannibal, where the algae led the FBI to Miriam Lass. A lot of crime shows play forensics up, but algae actually can be an important tool for helping solve a crime.

The presence of algae, or lack thereof, can tell us several things. Is there algae present in the closed organs of the decedent? If so, that tells you they were drowned or whether or not they were taken to a second location. What kind of algae? This can help us determine fairly accurately where the victim was drowned. This doesn't include bathwater or water with too few diatoms, such as ice water.

But how? Let's look into that.

First off, I will be using the term "Diatoms." If you are unaware, diatoms are a type of photosynthesising algae, so I will be using the terms interchangeably.

There are over 15,000 species of algae living in brackish, fresh water, and sea water. Ponds, lakes, rivers, oceans, and coastal areas all have different diatom communities, and using that we can identify where the victim might have been killed.

When you drown, liquid is aspirated into the lungs and enters the bloodstream through alveoli. This lets particles such as sediments, microorganisms, or pollen to be carried to organs and deposited in capillaries. This means that diatoms can be found in the organs of a drown victim.

So, if diatoms are found in distant organs or closed systems and are of a great abundance, the cause of death is most likely due to ante-mortem drowning. This lets us know that the victim was drowned and was not just dumped posthumously.

Thanks to diatoms acid resistant sillica shell, they can easily be separated from tissue using acid-digestive extractions, and they are detectable in burned or putrified corpses. This means that drowning as a cause of death could be determined in a burnt victim that was taken to a second location.

Algae is also being researched for its use as a time of death indicator. A study was conducted by forensic scientists, who found the diversity of algae on piglet bodies in water tended to decrease over time with a peak in diatoms recorded after 1-8 days of decomposition. This kind of work remains largely experimental, but it has the potential to be used for establishing a timeline since death (or submersion) in water.

Algae can be useful for linking criminals to their crime scenes, as diatoms can transfer onto clothing or footwear. Comparing microflora with the diatoms found could also give you a general area or type of water they were drowned in, as a swamp would have different algae than say, the ocean.

This evidence isn't damning in and of itself, but all evidence at a crime scene is valuable for solving the crime, and as such, algae can be an important part of forensics.

Thanks for reading! Have a good day and a cup of tea :)

Deduction Tips #16

The size of a bag is indicative of how much a person needs to carry, and usually we prefer to carry less things. When you see someone with a bag (be it a backpack, a purse, or anything else) think about why this person needs a bigger one rather than a smaller one, and what that says about the contents of the bag and the situation of the person carrying it

Observation 101

So, here we are. If you practiced your Mindset and Intuition, observation will be more useful for you. Obviously, in 1 post we can only discuss what is observation and how to observe better. In the future, we will go deeper and analyze scenes. For now, let's get started.

Some people think that observation is just looking around. But here is the difference: Looking around is passive, observation is active. There is something called "Passive Observation" but it is not the same as looking around.

Passive Observation: It is an automatic habit you develop. You don't actively look for details but you observe. For example, you shake someone's hand and later you can say it was a firm grip and he wore a watch even though you weren't paying attention. Obviously, details come with attention so you won't observe a lot passively.

Active Observation: You have a purpose and you channel your observation with this purpose. You want to observe as much as possible in the shortest amount of time. So, when you shake hands you don't just shake, you are trying to get a feel of his skin, you are looking for the brand of the watch etc. When you become active, more details are available to you.

Let's analyze this scene in a very superficial way. Sherlock listens to the victim's parents and while he turns his head, he notices something. He realizes that an object is not where it is supposed to be. It is just an instant intuition and passive observation. It appears he wasn't actively looking but still noticed it because he practiced observation for a long time and he can observe even when he doesn't give attention.

Obviously, we have a lot of examples of active observation so I won't go deep on that.(Basically, every scene where Sherlock makes a deduction is almost an active observation. Though, we will go deeper in the next posts.)We can't do anything about passive observation because it will come with practice. For now, let's focus on active observation.

How to Observe?

Even if you know what to look for, if you don't know how to look, it won't matter. (You will look for a watch on a man's wrist but miss the detail that it is a woman's watch. )

So, for the last 3 years, I did research about how to observe and still @amateur-deductions program is one of the best programs. 2 basic questions will increase your observation skills immensely. Those are: 1-What is missing? This question is important because like the example above(Sherlock notices what is missing, which is bust)you need to see what is not there but should be. Almost everyone buys dumbells as a pair. So, if you see a 5 kg dumbell on the ground, you should question where is the other one.(If there is another one.) If you ask yourself "What is missing?" you will see it easier.

2-What seems out of place?

You see a soldier but he is not shaved. Why? Maybe he left the military or he is lying. Whatever the case, there is something out of place and by asking "What seems out of place?" you will look for odd details. These 2 questions are not enough but very important for the foundation. In addition, never forget: “There is nothing more deceptive than an obvious fact.” Never take anything for granted.

Your brain will trick you when there is an obvious fact like that:

Wrong: This person wears a watch. A lot of people wear a watch so it is not important. I don't have to observe it.

True: I wonder what can I observe about this watch? What time does it show?

What to look for?

The answer to that question is simple: Everything. You can't take the risk of missing any details so you have to observe everything. After you observe everything, your observations will draw you a path and you will go deeper into some of them. So, observe everything.

This is a long introduction but a necessary one. In the future, we will go deeper. So, if you have any questions about observation, send them. For now, that's all. See you later.

Visualizing the Building Theory using BBC Sherlock

@amateur-deductions recently did a post on the Building Theory. In his words:

[The Building Theory] serves as a wonderful way to illustrate how much a deduction is a progressive process, with multiple little steps between observations and conclusions. It's also an amazing tool to analyze other people's deductions and break them down in a way that allows you to map out their trains of thought and learn from them

He provides an excellent explanation of how the theory works: basically, you think of the process of deducing as constructing a building, with observations and subsequent deductions representing bricks that are stacked on top of one another, building up to more complex deductions based on those original observations & deductions.

I’ve always liked this theory because it makes the process of deduction more tangible and visual, which helps me learn, and I know others like to use visuals to learn too.

I’ve mapped out deductions from BBC Sherlock before, so I thought sharing that here would help provide a visual supplement to @amateur-deductions​‘ work.

When Sherlock and John first meet, Sherlock asks: “Afghanistan or Iraq?”

You can watch the scene where he asks that here. And the scene where he explains how he got to that here.

While the show provides a decent verbal breakdown of how Sherlock got to that question, we can also visualize his process like this:

blue: observations // green: deductions made from observations // pink: deductions made from prior deductions & observations (level 1) // yellow: deductions made from prior deductions (level 2)

As you can see, Sherlock uses his initial observations about John to make deductions, and then uses those deductions to make additional deductions. All of this culminates in him asking John “Afghanistan or Iraq?”

Let’s break down this process a bit. We can think of this building as being made up of a bottom floor, and then two supporting sides that work together to build onto that bottom floor and also support the roof placed on top. 

First, the bottom floor:

When John enters the room, Sherlock looks up at him and makes four observations about him, which he uses to make two deductions.

1. stance + haircut = military

** Sherlock knows that these observations = military from knowledge he has about the appearance/behavior of people in the military.

2. looks around the room + says “bit different from my day” = medically trained at Bart’s Hospital

** Here Sherlock uses a combination of knowledge and logic. He knows that Bart’s Hospital is a well-known training hospital and if John is familiar with the lab that the pair are standing in (as opposed to a patient room), he must have been a student there.

Sherlock then takes those two deductions and combines them to create another: military + medically trained = army doctor. That deduction forms the base of the rest of the building.

Next, there are two supporting sides. Let’s call them the “limp” side and “tan” side, as those are the two observations that form the base of each.

First, the limp:

Sherlock begins with several observations: 

1. has a limp and uses a cane.

2. does not ask for a chair to sit in.

** Knowledge: Sherlock knows that people with limps may look for or ask for somewhere to sit.

From this, Sherlock deduces that John:

1. forgets he has the limp.

2. Why? Because the limp is psychosomatic.

** Knowledge: Sherlock knows about psychosomatic injuries.

3. Which means that trauma caused the limp.

Second, the tan:

Again, Sherlock begins with two observations, and each have their own subsequent deduction.

1. has a tan. = was recently in a sunny place.

** Knowledge: Sherlock knows that people get a tan from being in the sun, and that tans fade over time.

2. only has a tan on his hands and face. = was in a sunny place while wearing long sleeves, so he was not on vacation or sunbathing, but was on business.

** Knowledge: Sherlock knows that when people go on vacation to a sunny location, it is not typical to wear long sleeves or professional clothing but rather dress casual (shorts and a t-shirt, swimsuits, etc.).

Here is where Sherlock’s process culminates into the question. Relying on the deduction that John is an army doctor, and combining that deduction with these two new deductions (1) has a limp from trauma, and (2) was recently in a sunny place for business/work, Sherlock makes this final deduction: John is an army doctor who was recently in a war zone near the tropics. 

He cannot go further than this though, as there are a few locations that fit that description. So, Sherlock engages in order to get the information he needs: “Afghanistan or Iraq?”

~

I hope this provided a helpful visual example of the Building Theory - if anybody has any questions or wants me to go into more detail on any aspect of this example, please ask!

Sherlock & Co.

Small post today for me to scream about my newfound love for the Sherlock & Co. Podcast. I found it two hours ago and have been listening non-stop ever since. I cannot recommend this enough to BBC Sherlock fans, especially those who have been craving a 2023 take. There's even a frequently updated twitter/X by Dr. Watson himself (@DocJWatsonMD). They're making a modern dramatization of the entire original canon!!

The only breaks I've taken have been to literally screech about how excited I am and to write this post.

"How do you know the new clock is being built in Ankh-Morpork?" said Lobsang trailing behind Lu-Tze as he took a mossy, sunken path that led through rhododendron thickets to the monastery wall.

"I know. I'll tell you, the day someone pulls the plug out of the bottom of the universe, the chain will lead all the way to Ankh-Morpork and some bugger saying, 'I just wanted to see what would happen.' All roads lead to Ankh-Morpork."

"I thought all roads led away from Ankh-Morpork."

"Not the way we're going."

[amateur-deductions]

When it comes to the observation weeks in the training program. Could you elaborate on why we shouldn’t deduce then? Is it only about the time when we are doing the exercises?

Hello! great question, i gotta say i didn't write that program, but i did follow it, so i can only give you an answer based on my experience with it and with deduction as a whole. Unfortunately L isn't available to give you the original reason, but if i get in contact with them i'll make a post with their answer.

So, there's this quote from Sherlock which sums up the reasoning behind this very clearly:

"It is a capital mistake to theorize before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts."

During this stage of the program it is assumed you're coming into deduction as a complete beginner, and therefore that you haven't honed your observation skills yet. This means you'll inevitably be at a point where if you try to deduce you'll be doing so while missing a large amount of information, and fall into the trap of not knowing you're missing information and trying to work with what you have, which leads to often taking big leaps in reasoning to reach conclusions, because you don't have enough data to work with.

This is also why when i teach people i make sure they're at an acceptable level in their observation skills before i move onto other stuff. Later on in the process you learn how to make the most out of a situation where you have little to no information to deduce from. But that's a bit too complicated for a beginner, so it's important that they don't try to deduce until they have a solid grasp on what information they can gather

Aditionally, the training program, as incomplete as it may be, attempts to separate the process of learning deduction into manageable chunks. That program was written during a time where the community was much bigger and everyone attempting to find some way of learning this skill. Everyone was coming up with solutions to their problems and sharing them in the community, and that program is an attempt to solve the overwhelming feeling that comes with trying to learn a massive skill with multiple possible points of entry. It segments it into manageable, organized chunks for people to have a neat way of getting started with deduction, and one of those chunks is just observation, since it's complex enough of a base skill to have its own section

You want something to do? See what, if anything, you could deduce from this photo

Marvellous!

So a guy in his teens around 14-16. Hasn’t cut his nails in some time. Either didn’t have time or was to lazy. His room is well room-temperature. Not warm but not very cold. Puts some thought into his appearance. It’s probably dark outside, if yes then Europe/Asia, basing on the appearance I’d go with Europe.

(Almost have)

The photo is quite low quality so it might have been with an old phone or a computer camera. Doesn’t do a lot of manual labour probably - it doesn’t mean that none at all. Is comfortable enough in his appearance to post a photo of himself.

I was supposed to post this yesterday but didn’t. What did I get right?

[consult-sherlockholmes]

Just curious how do you employ your deductive methods in every day life(john)

I just observe. It is like a reflex, I cannot shut it off. Just looking at John creates an influx of data and information about his mood, his plans for that day, how he slept, his condition and many other points. His physical state, whether he is in pain, tired or hungry. Whether he had a good night's sleep depending on his posture or tension around his eyes or his shoulders. If he is planning to meet up with someone depending on his choice of clothes and aftershave on special occassions. His gait and movements show whether it is a good day or if he is in any pain. I can tell if he is worried or wants to talk about something by the furrow of his brow. When he keeps checking his phone repeatedly he is waiting for a message, for example when he is concerned about his sister not answering his texts. I can tell what he is thinking about, visible in unconscious movements like twitches, the frequency with which he licks his lips or the direction of his gaze. Whether he craves something when he keeps glancing towards it. The tone of his voice and how talkative he is can show many things. When he is fidgety and barely able to sit still in his chair, it means that he is bored and would like to go out on an adventure. Of course I can deduce many more things but I think I provided more than enough examples. I can deduce John better than anyone else, because I am very familiar with him, have spent so much time with him and analysed his behavioural patterns. Although it took me some time to truly realise what he feels for me, but sentiment is not my area of expertise after all. He is the exception, even concerning my deductions.

Deductions are cool.

As someone who's learning the science of deduction, it feels like how I imagine it would be like to not know how to read. A world of signs, of letters and words forming information if you just knew how to decode it. Learning to make deductions feels like finally learning to read, finally really seeing everything around you and connecting it to things to get information.

It's like learning a new language, one that's everywhere, all the time, just ready for you to notice. There's so much to be gained from that language, I think it's beautiful, and I'm happy to have one more way to quench the thirst for knowledge.

[studies-in-the-art-of-deduction]

Hi!!! How can deductions be used in day to day life, or like, usefully? And how have you made useful deductions? Sorry if that made little sense

Hi! I see you sent this question in the past two days, i'll gladly answer it, but in case you send any other questions in the future and i don't answer them as quickly i'll inform you that usually all the questions of the week are collected in my inbox and you'd get your answer on a Monday (this week i had some scheduling problems so i pushed it to Wednesday), so if you don't get as quick an answer next time just wait for Monday!

Now, regarding your question! There's many ways deduction can be used in daily life, sometimes it even depends on what you do for a living. For example i know psychologists and other healthcare profesionals have to rely on non verbal communication and information they gather from observation, along with what they're told, since patients can't be relied upon to be transparent and honest all the time, or even know what information is releant to share. In this case deduction can be massively useful.

On a more general note, it depends a lot on the type of relationships you have, i know people who use deduction to interact with their friends, it allows them to know when they're feeling upset or worried, and about what, and act accordingly, all without needing to do more than just glance at them. I know people who use deduction to navigate social situations because they're not good at interacting with people and having the extra information deduction provides helps. Personally i'm someone that introduces deduction into everything i do, from acquiring helpful knowledge when talking to superiors, to knowing what waiter is best to call over at my table cause they've gotten more hours of sleep.

I recommend you watch Sherlock, House M.D., The Mentalist, and all of these deduction heavy shows that sometimes showcase how these characters use their skills casually, it's really not much different than what you see there. If you want a blog that really goes into casual uses of dedduction i'd check out @froogboi 's blog, it's full of everyday life uses of deduction

Stoic Perspective

This post will be some kind of addition to mindset, but also very important part. You might be wondering how it is related to deduction and Sherlock Holmes but even though we don't see Sherlock talking about Stoicism, he follows it in most cases. (Mixed with Cynicism which started around the time Diogenes lived.) So, let's see how Sherlock uses and how we can use it in our daily life.

Remember this episode? Season 1 Episode 3. Sherlock solves 5 cases in a row with some time constraints, stress factors, etc. In one scene, Watson asks, "There are lives at stake Sherlock! Actual human lives. Just so I know, do you care about that all?" and Sherlock answers with a brilliant answer: "Will caring about them help save them?" and Watson says "Nope." and then Sherlock says "Then I will continue not to make that mistake." Obviously, they show it like Sherlock doesn't care about anyone and is an egocentric narcissistic robot but that is certainly not the case. If you watch other adaptations(Granada, Elementary or even the books)Sherlock cares about other people, but not in a way normal people do. I am pointing out this scene because it shows us the attitude and mindset of Sherlock. Let's see how we can apply this in real life:

1-Caring without Emotions

"Emotional qualities are antagonistic to clear reasoning." -Sherlock Holmes

After watching Sherlock we shouldn't try to be like Sherlock, especially if we don't understand how he thinks. When he says, caring won't save them it doesn't mean he doesn't care. It just means it is not relevant and emotions won't help them in any way because it will cloud his thinking and deductions. So, what can you do in situations where stress is high and your emotions come to the surface?

1-Recognize them: Don't suppress or act like you don't have them. Just realize they are there and act accordingly. If you say "There is nothing wrong with me. I don't feel any emotions right now..." then you won't be aware of the affect they have on you.

2-Think Clearly: It is easy to say but hard to do. How can we think clearly? What does it mean? It means you have to use the relevant data and eliminate what is not. If you want to think clearly, you have to recognize your feelings, emotions etc. You have to be aware of them at every step so that when they are affecting your reasoning, you can overcome them and keep going.

3-Follow Your Logic

Sherlock doesn't call Moriarty after he solves the case because he wants to use time advantage. He wants to work on other cases and because of that, he doesn't call Moriarty. Watson is reacting with emotions and says this woman was covered with bombs all this time. Although Sherlock cares about the woman, he follows the logic. If he uses the time to his advantage, he can save more than one life but if he reacts with emotions, he will just save one. So, use your logic and act accordingly.

2-Perspective For Problems "External things are not the problem. It's your assessment of them. Which you can erase right now." -Marcus Aurelius

This can change a lot of things about how you see your problems. Let's say you have a lot of work to do and after a long day you are going home. When you arrive there, you realize your house is on fire? How would you react?

I believe, most of us would be full of emotions. Why did this happen to me? Why is life not fair? My life is over. What will I do now?

But if we just can change our perspective and practice it in our daily life we would have a very different and constructive response to the situation. Now, here is the perspective I am talking about:

Now think about the same scenario. You see that your house is on fire. You think "Can I do something about it?"->"Yes. I can call the fire department." or "No. It is too late. Everything is turned to ash." In both cases, you don't have to worry because it is already done. You can't travel back in time so you have to create your plans for the future. You can't waste time thinking about the past because it will limit your capacity to act on the future.

If you use this perspective in every situation, eventually it will become automatic and your emotional reactions will not be as strong as it is now. This way, you will be able to use your logic more easily and solve the problem you have.(Or you will stop worrying if you don't have a problem.) This is probably the fundamental perspective of Stoicism.

3-Expressing Emotions

I won't go deep into the Jungian Shadow or deep psychology of the emotions and suppressing etc but we have to be aware of this fact: The fact that if you don't express your emotions in some way, it will come out later bigger than it was.(Also, you won't be in control.)

If you watched Elementary, you know that almost in every episode Sherlock express his emotions to Watson.(Or to someone else. Which by the way is a more human adaptation of Sherlock.)He talks with her about what he feels and thinks about the situation because he can't deal with them alone. We can't deal with them alone too so we have to find some ways to express them. Here are some basic ones: 1-Talking to your Watson

If you have someone you are close to, then talk to them. Explain your feelings and emotions as clear as you can be.

2-Keeping a Journal

You won't always have an opportunity to talk with somebody so you need to talk with yourself clearly, which is what journaling does. You use words and getting things out of your head so you can analyze them more clearly. Just write and then read them aloud.

3-Physicality

If you like to work out, run, go to the gym or do any physical activity, do it. It is especially useful for anger and sadness. Try and find whatever works for you.

So, that is a general look at emotions and how to live with them. After you read this, you won't immediately detach from your emotions and act with your logic. This post is not enough, so you have to do your own reading. Some suggestions for reading: Meditations-Marcus Aurelius (Excellent example of journaling in a stoic way.) The Handbook-Epictetus Ryan Holiday's books(All relates to Stoicism)

And one last thing. Always remember these wise words:

"You have power over your mind, not outside events. Realize this and you will find strength." -Marcus Aurelius

Culturing Bacteria in a Petri dish With Agar; an experiment/observation

Today's post is quite different from the usual;

So, we had to do a project in the educational institution I study in; Which was growing bacteria in a Petri dish with agar.

Today, the results came in, but our professor insisted that we have to throw the dishes in the bin. I didn't give up there; after talking to her for a short amount of time, she accepted that I can take the dish with me to my flat, and have a look at it with microscope.

I still cannot comprehend why other students were disgusted by them; they are beyond wonderful.

Allow me to explain this astonishing journey:

What exactly is agar?

Well, agar, derived from the minute aquatic organism known as seaweed or algae, specifically the types Gelidium or Gracilaria, is a widely employed gelling agent. Found abundantly in the coastal regions of East Asia, particularly Japan and South Korea, it undergoes a process of cleaning and extraction to obtain agar in its usable forms of dry strips, flakes, or powdered consistency.

Now, when it comes to the realm of cell and bacterial culture, agar assumes a pivotal role as a solidifying and gelling medium within culture media. Its remarkable gel-forming properties allow for the creation of a three-dimensional matrix, offering an ideal environment for the growth and sustenance of cells and bacteria alike. Nutrients and metabolites find efficient transfer within this agar-based culture medium, while its structural integrity ensures the confinement of cells to designated areas.

Agar's utilization in cell and bacterial culture provides a multitude of advantages, including its ease of implementation, stability, and facilitation of cell separation procedures. The versatility of agar finds application in diverse fields, from microbiology to biotechnology and pharmaceutical industries.

Bacteria can be found on any surface, anywhere.

I decided to pick them up from my shoe soles.

After extracting bacteria from the soles of the shoes, I cultured them in an agar-containing Petri dish. After one week, I observed bacterial and fungus growth in this environment. Here are some images I captured with my microscope:

Wonderful, aren't they?
