Why Use Binary? - Computerphile

hmm - so when building a machine for processing in decimal, i may need only around 1/3 the number of components (like single-digit adders, storage registers, etc.), but i guess, each of these components would then have to be 3 times as complex (i.e. have 3 times more sub-components). right? or wrong?

Yes yes no no no yes no no yes

This guy is so interesting to listen too!

Correct me if I'm wrong,
But the MLC, TLC and QLC technology is doing kind of the same thing...

i only understand like 3% of what this man is saying but i would watch him explain anything

Fascinating video. thanks

hahah Samsung 3 mini :)

Is that the guy who narrated Planet Earth?

Some serious curse of knowledge going on here. He knows his subject matter so well he can't explain it without using technical terms (like bi-quin and thermionic valves) that few people watching this video would understand if they didn't already understand binary.

numberphile stuff

😅😅😅

-bi-quin
-by what? (omg did he just said by-queen?)
-bi-qui, bi-quin

😂😂😅

Is this a serious question? Hex or base 12, perhaps, but decimal is the worst of most worlds.

It’s a lot easier to use little on/off switches than little ten sided dials.

Ternary would be an even better option. About 64% more efficient than binary for storing a random data set. (Base e is perfectly efficient but not much better than 3 and much much harder to apply)

For the experience and better knowledge of the Stock market exchange, I'm glad I meet Metro_kelvinfx on instzgram he alone was able to satisfy my curiosity in the game. Thanks to him I'm earning massively though he's trading platform .

one of the best story tellers ever

Why not Use Ternary?

The real reason? Computers took a lot of space in the beginning some were entire buildings. You only need 8 transistors to count to 256 in binary, you need 10 to count to 55 in decimal.
Binary Maximum Count: 2+4+8+16+32+64+128=256.
Decimal Maximum Count: 1+2+3+4+5+6+7+8+9+10=55

Why use base10? 🤔🤣

Thank you very much for this video :) It was very educational for me and interesting.

But I do want my guitar amp made with valves :) interestingly it's rare to see the bias in the grid in guitar amps, it's mostly in the cathode and the signal is in the grid. I guess you get better amplification when the signal is the control voltage in the grid, you can make cathode have rather negative voltage.

Mother nature uses base4 for the DNA code. Why not use that?

Binary is the purest form of counting. Everything else is human construct.

It's a shame that all modern computers rely on binary, there are logical advantages to trinary, and many different ways you can implement it in terms of electrical components.

There are 10 kinds of people in the world — those who understand binary and those who don't.

turkish translation is putted automatic. it could be good if you can fix that for your turkish followers

Boy, that samsung joke at the end didn't age well.

Well you probably wold not get those 3 degrre burns anywhy, because you phone , let alone the batery to run the thing fir more than 2 secoonds, wokd not fin in your pocet if the phone was made with thermionic valves but tge comparison made me smile anyway, thanks for another great video

Digital Communications use multiple voltage levels to pack more bits per clock cycle though. PAM (Pulse Amplitude Modulation) is used in Ethernet and QAM (Quadrature ditto) in WiFi.

Because it is easier than quaternary when constructing logic gates and latches. But solid state storage uses multiple voltage levels.

didn't understand anything about bi-quinary, good we dont use them

Probably should mention Binary Coded Decimal. That's where you use 4 bits to encode each decimal digit, and just don't use 0b1010, 0b1011, 0b1100, 0b1101, 0b1110, 0b1111.

but why not balanced ternary?

Why not?

He is an expert

Not to be dramatic, but I would die for this man lol

Who else came expecting him to talk about ternary computers?

Wow! 🤩 Awesome explanation! 🥳🎉👍🏽💻📱🖨⌨🖱

Two is a lot

💚

In summary: decimal is only 3.3x more efficient than binary, while being significantly less reliable and harder to implement. It's simply not worth it.

I guess I can call my Marshall tube amp a Marshall thermionic valve guitar amp now.

why cant i save this video?

This is getting me deeper into the rabbit hole of programming.

Can't belive i watched this now and understood why binary after 14yrs in industry

The disadvantages of decimal don't outweigh the saving of storage. I wish you lots of luck when you want to reliably multiply just two 2-digit numbers, reliably meaning no voltage will ever be misinterpreted. Let alone doing it on a chip with 10^9 transistors.

Binary is due to Boolean Logic (which pre-dates the computer) rather than valves and switches being on and off, surely.

how about just use letter then
