Welcome to today's episode of Nerd Knowledge with Kari!

In today's episode I present to you, the 'Waldrapp' (Genrocius eremita) better known as the 'bald ibis':

This bird is one of the world's first protected species, which was a decision made exactly 520 years ago, in 1504, by Archbishop Leonhard of Salzburg. - (side fact: Salzburg is a state and a city in Austria, the country has 9 States in total, those being: Vorarlberg, Salzburg, Tyrol, Carinthia, Burgenland, Vienna, Lower Austria, Upper Austria and Styria)-

Back to the Waldrapp.

Despite being one of the world's first protected species it still went extinct. .

..

…

PLOT TWIST It did in fact make a return, a sequel you could say.

The Waldrapp has slowly started to return to Europe but is most commonly found in coastal areas and on cliffs in Marocco, Turkey, and Syria.

But how does it look?

And how big is it?

Good questions fellow knowledge seeker!

The northern bald ibis is a large, glossy black bird, 70–80 cm (28–31 in) long with a 125–135 cm (49–53 in) wingspan and an average weight of 1.0–1.3 kg (35–46 oz). Which to me is quite impressive.

Well, this is all for today. Have fun annoying your friends with new facts.

Have a good day and sleep well!

Hi and welcome to another episode of Nerd Knowlege with Kari!

In this episode we'll be talking about the Boeing 737 MAX 8, the MCAS system and why said system was even installed, why it failed.

(this ist the actual Cockpit of a 737 max 8)

One lovely day someone at Boeing woke up, saw that Airbus (the Europen counterpart) had decided to renew its engines, and went: "Oh shit we have to do that too". And they did, just not well.

The Boeing 737 Max 8 failed 33 out of 89 tests, which is a lot.

With a too-high AoA (angle of attack) at take-off caused by the weight of the new engines, they could lead to possible danger.

So Boeing decided that a system that corrects the aeroplanes nose if needed. And so the MCAS ( or Maneuvering Characteristics Augmentation system [say that 5 times in a row I dare you]).

One would argue that pilots would need proper training for a new system, but not Boeing. Why?

Because it's cheaper to give pilots a one to two-hour iPad course. And I'm not even joking, that is literally the training they got.

Now what made it fail?

The MCAS system relied on one single sensor, and that sensor gave wrong AoA data, causing the system to automatically push the nose downwards.

The pilots could push up the nose as much as they wanted, the system would always push it back down. The pilots did not know how to fix this problem which then led to two horrible crashes.

I would like to add that having the finance guys take over the company was a bad decision.

I hope you're doing good!

Hello and welcome to today's episode of Nerd Knowlege with Kari!

Today's theme was suggested by @rat-in-a-suit, shout out to you :D

Today we will talk about Cassetes!

I am very bold to assume that not everyone knows what this is so here's a quick definition:

a sealed plastic unit containing a length of audio tape, videotape, film, etc. wound on a pair of spools, for insertion into a recorder, playback device, or other machine

(Definition from Oxford Languages Dictionary)

Now that you have a brief idea of what it is I want to explain to you how they're built, who came up with them, and when they started to be sold.

Compact Cassettes have two miniature spools between those there is the magnetically coated, polyester-type plastic film (Also called magnetic tape. Side fact: The original magnetic material was based on gamma ferric oxide Fe2O3).

The audio is recorded onto it by using the incoming sound wave, having been converted by a microphone into an electrical signal, which produces a time-varying magnetic field in the gap of the magnet. As the tape moves past the recording head, the powder is magnetized in such a way that the tape carries a record of the electric signal.

Now that that is out of the way we can finally discover who came up with these beautiful sound devices.

The Cassette tape was invented by a Dutchman called Lou Ottens (21.06.1926 - 6.03.2021) and his team at the company Phillips, they released the first Cassette in 1963.

Short after the Walkman was released to the market, a Walkman is a portable cassette player, they were brought to the market by Sony (who else honestly) on the 1st of July 1979 (The model was named TPS-L2 which I found on eBay for a whopping 2000 Euros or 2177,50 US Dollars)

Shortly after the Cassette, we got CDs then iPods and now we have online streaming platforms too! This makes music easily accessible to everyone!

So put on your favorite music and enjoy the rest of your day or night!

Hello there! Welcome to another episode of Nerd Knowlege with Kari!

Today we will talk about something we all love (and if you don't you probably eat small children /j), that being Music!

Listening to music can improve your mood listening to (or making) music increases blood flow to brain regions that generate and control emotions. The limbic system, (which is involved in processing emotions and controlling memory) “lights” up when our ears perceive music. The chills you feel when you hear a particularly moving piece of music may be the result of dopamine (a neurotransmitter that triggers sensations of pleasure and well-being)

It can also reduce stress levels and help you feel your feelings. Like when a song makes you incredibly happy or very sad.

Also music activates almost all parts of our brains! Music has been shown to activate some of the broadest and most diverse networks of the brain. Of course, music activates the auditory cortex in the temporal lobes close to your ears, but that’s just the beginning. The parts of the brain involved in emotion are not only activated during emotional music, they are also synchronized. Music also activates a variety of memory regions. And, interestingly, music activates the motor system. In fact, it has been theorized that it is the activation of the brain’s motor system that allows us to pick out the beat of the music even before we start tapping our foot to it!

That's all for today, put on some music and have fun, my friends!

Hello people and welcome to Nerd Knowlege with Kari!

Today we will touch on the topic of books!

We all know, and love books but how were they first made? Who made them and why? And how have they evolved?

All of these questions and more will be answered today!

The history of books starts with the fact that humans learned how to paint, developed alphabets, and began to write.

Humans have always drawn or written down things, like cave art for example.

We have done this to document thoughts or events, write down prophesy ect.

The first 'books' were clay tablets used in Mesopotamia (today known as Iraq) this was in the 3rd millennium BC ( the 3rd millennium of BCE is the year span from 3000 - 2001 BC).

In ancient Egypt, they started using the very well-known papyrus probably as early as in the first dynasty.

In China the first printing of books started somewhere between 618 - 907 CE (The Tang dynasty period).

These are only a few examples, but you can still see that books and writing are things that evolved everywhere, partially completely independently.

In the Middle Ages in 1440, the printing press was invented by, act shocked, a German man named Johannes Gutenberg. This revolutionized book printing, books could be made faster and in more quantity.

This invention spread fast throughout Europe and then started to reach other parts of the world, leading us to where we are today! Books have become significant for history and help us learn every day. Regardless of which form you read them in, keep on reading. Learn new things!

I wish you a good morning, afternoon, evening and night!

Hi and welcome to another episode of Nerd Knowlege with Kari!

Today I will introduce the loveliest little boi, the Pink fairy armadillo (bionominal name: Chlamyphorus truncatus)!

I have to say that I quite like these guys, and you will too!

That's right, I see you, you fellow introverted creature.

What?

No, I'm not talking about you reader.

I'm talking about him!

The Pink fairy armadillo is usually spotted alone when in the wild- if they even are, because, just like us, they tend to stay at home and not exit their natural habitat. Around 95% of them die within 8 days if taken out of their natural habitat.

Now to the details ->

The pink fairy armadillo is the smallest (and cutest) armadillo, it's found in the central and scrub lands of Argentina and was discovered in 1825 by Richard Harlan (American paleontologist[a person who studies fossils and life from early geologic periods], an anatomist, and physician).

The pink fairy armadillo is 90–115 mm (3.5–4.5 in) long, and typically weighs about 120 g (4.2 oz). It has two shells: the Thermoregulation shell and the external shell. (If you want to know more about its skin and shell here's a link: https://www.scientificamerican.com/article/pink-fairy-armadillos-have-a-weird-double-skin-not-seen-in-any-other-mammal/)

Sadly, since they don't come out much, almost nothing is known about them, except that they probably eat ants and plants and are mammals but that plus what I've told you is sadly it.

Maybe we should all change career paths and start to study these little buddies.

I Wish you a wonderful day, sleep well!
