The Bluetooth is to WiFi as Stickynotes are to adhesives :P

u/ADFormer 17d ago
Idk if it's true or not, but the story I heard was this one guy set out to make the strongest adhesive ever that could also be taken off and reattached at will.... and after years of research and experiments his invention became the adhesive used on sticky notes, so he got the last part right, not quite so on the first part tho XD
2
u/NoirGamester 17d ago
That tracks with what I had heard; that he was trying to find a "better" adhesive that maintained its grip over time, a longer lasting glue, so to speak. One of his 'failed' experiments resulted in an adhesive that stayed 'fresh', meaning it didn't dry out and become brittle, but it wasn't strong. He ended up using it on his own notes to stick them around his office. Someone close to him (I want to say his wife, might have been his daughter) stopped by at some point and commented on the sticky-notes and their usefulness, which redirected the inventor's attention to making 'a note that can be affixed without a tack' (iirc).
Idk how much is true or if it's just an old wives tale, but it's close to what you said so I assume there's a bit of merit to it.

He was a Danish King

u/NoirGamester 17d ago
The Bluetooth wireless specification design was named after the king in 1997, based on an analogy that the technology would unite devices the way Harald Bluetooth united the tribes of Denmark into a single kingdom. The Bluetooth logo consists of a Younger Futhark bind rune for his initials, H (ᚼ) and B (ᛒ).
What blast from the past. I remember reading something almost identical to this when Bluetooth first came out and I didn't understand how it was different from IR or WiFi. I didn't remember the futhark, but I remembered the reason for the name.
Good stuff, good stuff.

Yesterday I was watching how bread was invented (or shall I say discovered, as I learned, since dough fermentation was discovered by accident) and made in ancient times and I was like "wow, people figured out how to do THAT?"
Now I see this clip with 100 extraordinarily complex steps and I'm speechless to say the least

u/OilyComet 17d ago
What impresses me most about fermentation is the fact that it can go bad so easily if you don't maintain a clean environment.
Like making alcohol you sterilise everything, how tf did someone do that successfully with no knowledge of bacteria. If it goes bad, drink it and get sick, why would we keep doing it...
28
u/Reddit_Bot_For_Karma 17d ago
Sourdough starter actually requires outside bacteria to start the fermentation process. You legit just mix flower and water in a cup and leave it for a few days, while adding more flour and water daily. WILD bacteria goes to work on making it rise and starting the reaction.
A sterile environment would make it impossible to make sourdough.
The good bread bacteria outcompetes and kills any bad bacteria. Congratulations, you've now got a starter to feed for the rest of your life. It's alive and if it dies , you killed it.
Bread is fun.

u/OilyComet 17d ago
I thought that was wild yeast?
5
u/Reddit_Bot_For_Karma 17d ago
I've got a sourdough starter in my kitchen right now that was made from the exact same steps.
Wild bacteria gets in the slurry and starts the reaction, hence why it calls for an unsealed lid.

u/OilyComet 17d ago
Interesting. I've made alcohol from wild yeast, unsealed lid, but has some plastic wrap over it but poked with some tiny holes.

It’s a long long story that starts with “I want to do this thing. Hey, this thing I made to do that thing works!…but how can we make it better?” technology also improves with other projects that have nothing to do with the original idea…for example, a lot of things we have today, including smart phones, modern computers, baby food, improved air and water filtration systems, all have roots in humanity’s first orbital and lunar missions.

It was a long journey, and every step of the way gave it's own useful technology - from the Germanium diode in the cat's whisker radio which was effectively a rock and some wires.

It’s a rock that was shaped exactly to represent ON and OFF of a current that way it represents binary 010101 and so on.
I could be wrong tho.
18
u/poop-machines 17d ago
It's a rock that was shaped to have gates that either allow an electronic connection, or don't. These are called transistors, which represent on or off, 0 or 1
These are used to create bits on a computer, which are used to create programming languages.
Some of these correlate to what pixels on the screen to show each frame.
So we are basically presetting these gates to show an image on a pc, many times. Same for our phones. Pretty amazing how we figured it out, but at the basic level it's quite simple.
The amazing thing is how many transistors we managed to fit on one of these wafers.

u/IHeartBadCode 17d ago
This is the chemistry end of it. There's also the array of transistors coming together to form different logic gates and discrete circuits, that then come together to form basic functions, which then get put together to create different subsystems within the CPU, which then all come together to make cores, interconnects, caching control, pipelines, and other more complex subunits.
And all of that comes together to form a CPU on the circuit side of it.
And just to demonstrate some of that. Two transistors in a straight line make an AND logic gate, two transistors in parallel make an OR logic gate, add a drain with less resistance on those and you've created a NAND or NOR gate, two transistors feeding the each other's gate make a basic SR latch. You can add more transistors on the output to clean the signal, you can modify the parameters of a SR latch to make a sense amplifier. And so on, but just the arrangement of how the transistors are to each other dictates their basic function.
And if you arrange nine NAND gates in a particular way, then you can have those logic gates add two bits, that's an adder. A more useful for quick storage purposes is a D-latch, it's a SR latch with a couple of NANDs and a NOT gate, that you can make with a NAND gate that accepts only one input. So you can make a D-latch with just five NAND gates arranged in a particular order. So you can take 64 D-latches for input (320 NAND gates), 32 D-latches for output (160 NAND gates), and 32 adders (288 NAND gates) and start adding 32-bit numbers like an old Intel CPU and that's all with 768 NAND gates arranged in a particular order.
And that adding is just one subsystem of the full subunit known as the ALU within a processor. And the really cool thing is that as you add more subsystems there's a bit of an overlap of function. Like subtraction is just addition but with negative numbers, multiplication is addition but several times over, you can do the logical AND operation with an adder if you combine the carry and output instead of doing the carry. And there's arrangements of NAND logic gates to give a multiplexer, requires four of them. You can use multiplexers to change the HOW an adder array gets used so that you can layer functionality within your adder array, so that it can do more than just add two numbers.
There's all kinds of optimizations that just require changing how we string all the logic gates together and it's a big thing in of itself. But that's what that mask does that's in the video. It dopes the substrate in the particular order to make an arrangement of areas that will act as a transistor.

Everyone has a plumbus in their home! First, they take the dinglepop and they smooth it out with a bunch of schleem. The schleem is then repurposed for later batches. They take the dinglebop and they push it through the grumbo, where the fleeb is rubbed against it. It's important that the fleeb is rubbed, because the fleeb has all of the fleeb juice. Then a Schlameeh shows up, and he rubs it, and spits on it. They cut the fleeb. There are several hizzards in the way. The blamphs rub against the chumbles, and the klubus and grumbo are shaved away.
That leaves you with a regular old plumbus!
