The Digital Age in an Analog World

[MrJackoman55]

when ever i watch Kaku I always wait for the "HOWEVER" it makes me lol

[darkdragonsoul99]

Well that is something I did not know lol

[ftlqed]

But, if you go back to real analog, then you get infinite information back because if free space a mixer can hold infinite information, but the digital can only compress though routine.

[ryangemini24]

what the hell is a zoracs?

[Trollolol30PX30]

@ryangemini24 Knock knock.

[gokuo64]

Actually, I've heard that when things are downloaded over and over again, some of those ones and zeros get lost in the process. A few don't make a difference but after a file is copied millions of times, millions of ones and zeros may get lost resulting in a lower quality file. Check out some of the old youtube videos from 2005 or 2006. Most of them look OK, but can you really say they are crystal clear?

[Windbringer]

@gokuo64 Because in 2005 - 2006, youtube only had 240 and 320p. Now the most common video is 480 and 720p (HD). And yes you may lose signal but it is easy to replace.

Example:

The "digital (binary)" of 25 is: 11001, If you somehow lost signal, say it became 110x1 where x is the missing code. You can calculate what the signal actually is.

Just place it with either 1 or 0.

You then have 2 possible answers. 11001 or 11011 which = 25 OR 26.

With logarithm, you can determine which it is.

[sexyloser]

@gokuo64 Youtube videos from 2005 and 2006 were never crystal clear.

[Smokemalboro]

@gokuo64 file copying does not work this way, take for example this, we have file "A" based on your understanding File "A" becomes file"AB" and file "AB" becomes file "AC"so on and so on, it doesnt work this way if you Copy file "A" or downloaded it, File "A" becomes file "A" there are no zeros or ones lost in the process .you can download File "A" millions or billions of times and there will be no difference who ever you got this information from is a idiot

[MattttG3]

this guy is one of the smartest people in the world. all his videos are amazing, god bless Dr. Kaku

[ObliviuxProductions]

xeroxception

[vinnievinvin99]

@ObliviuxProductions yo dawg i herd u liek copying, so i put a copier in a copier so you can copy while you copy.

[evildragon777]

I would totally let Dr. Kaku massage my signal.

[Rospandan]

will you be my grandpa?

[Darkslpsandstuff]

oh.. so you when you get copies that make thoughts more vivid we lose thoughts OMG... I actually understand this.

[technatezin]

The amount of information "loss" is dependent on the compression algorithm whether it's lossy or lossless and also on the resolution in which the information is digitized.

If you increase the resolution for digitization high enough the margin of error in reproduction becomes negligible and inconsequential for it's intended purpose. Human senses for example can only detect "errors" within a certain discrete scale. Go smaller than what's humanly detectable then the data "loss" is not important.

[Windbringer]

@technatezin That's actually was not the point at all. =)

[technatezin]

@Windbringer Yeah, right. Listen carefully to what Michio Kaku said in the clip. If you don't understand it the first time then listen to it over again. I'm sure it will come to you after a while.

Information loss is not an issue when digital reproduction goes beyond the resolution size of what the intended audience could reasonably detect upon reception of the information.

[Windbringer]

@technatezin It's hard to convey sarcasm through youtube comment. My point was, you just wrote what he said so...

[est101010]

Analog vs Digital is like RAW vs Jpeg.

[pantherdance1991]

michio kaku can make a computer with sticks and mud

[ganjahyute1]

@pantherdance1991 am "deading" with laughter

[robertgaudlitz]

if mind really is sexy, that guy must have a run with the ladies like james bond :D

[gobipill]

Lol I've always wondered what this digital thing was about. I thought it was something about clock hands vs numbers lol

[arkangelio]

Basically. Digital gives you more control.

[letsif]

Quality sacrificed to convenience. Compare vinyl to digital recordings. Vinyl has more depth and ambience. Same for video compared to film. Film emulsion allows light to penetrate the layers of celluloid emulsions and projected through with light creating an imperceptible flicker that is visually warmer and deeper. Same for still photography. Digital is flatter and cold. Things are improving in the digital world which someday may equal or better analog. But not yet.

[kossxf]

This is why you should never buy those super expensive gold-plated HDMI/DVI/etc cables. The signal is digital; either you have it or you don't. You can't improve the quality of your 1's and 0's

[Loolanga]

@kossxf Yes there are reasons to buy those gold plated cables. If there is interference on the lower quality line then to lose chunks of data, higher quality line = less loss of data.

[kossxf]

@Loolanga If you're "losing chunks of data" or any data at all, your cable is defective. When was the last time your monitor went fuzzy due to "interference?" Never. Unless your monitor, cable, or computer are defective.

[Cannsanity]

Imagine hitting on someone with 1's and 0's.

[studiogpk]

I always come to watch one video.. but end up with watching approx 20+... :( I hate Bigthink..

[elflordbob1]

binnary code

is a bitch because the 5 seconds it takes to convert a number from base 2 to base 10 is annoying

[Music1sgreat]

@elflordbob1 You mean from base 10 to base 1010?

[elflordbob1]

@Music1sgreat ...

binary code is in base 2

100010110101010101010

as far as converting to a higher base it may be base 20 something but we use base 10

and conversions of bases is easy...excpet with numbers like 564156135131341351531base 6 convert to base 7 those are a bitch

[Music1sgreat]

@elflordbob1 Umm, I don't think you got the joke. 10 in base 2 is equal to 2 in base 10 and 1010 in base 2 is equal to 10 in base 10.

[DarthScosha]

ha ha if only our cells were digital

[oatstralia]

That awkward moment when you watch this video in 240p...

[videouser654]

Analog is all blurry? 240p does the trick...

[ptuku]

@videouser654 he explained it in the vid... the less 0 and 1 you use, the less info it contains and the more distorted (compared to the original, or analog input) the output will be ;) (because there is data missing)

[videouser654]

@ptuku The thing is that, can't you replace the the numbers between 1 and 0 to more 1s and 0s?

[ryanellis999]

Yeah, but what about when someone rips this digital video and doesn't save it at the best quality in digital terms and reposts it with worse audio and video quality on another website?

[herbrantje]

Computer are digital cause they calculate on 0/1.

M. Kaku says that a quantum calculation is based on a number of outcomes between 0/1, read from the echos of radiated atoms.

Would this mean that a quantum computer is an analog machine? Or rather a kind of detailed digital machine...?

[oSniper]

what if i xerox'd a piece of paper full of 0's and 1's

[sivadfa]

@oSniper The 0s and 1s get fainter and fainter...

[vitto]

wow...i'm the visitor number 4666...lol

[TheRaisedThumb]

*softly chuckles* xerox...

[danialmouse]

After I Copy 0s And 1s A Million Times Do You Know What I Get...I Get Bored

[shraka]

@danialmouse That's why you get computers to do it for ya. ;)

[fackyoudude]

The different really is what do you want. Like talk to ur friend: u made ur gf happy yesterday (digital) v.s. what does it sound or look like when u make ur gf happy (analog), just like 99% of the internet.

[OnIyOrange]

2:00. This guys got so much game.

[Capilee]

@OnIyOrange im dying right now! XD

[poormanlat]

i could listen to this man all day long

[truthseeker010101]

Loom up an old speech from 1950 and watch some analog on youtube

[Capilee]

@truthseeker010101 but it's already digital... analog has done it's damage, but digital technology has preserved that speech for 60 years through the 1's and 0's of memory storage

[Heifsin85]

This guy is such a boss. Look at his smooth talking, his wink and point at the camera at 1:59

[fingerboy18]

Analog is a continuous function and digital is a discreetly sampled reproduction. Every natural phenomena we experience is analog.

48kHz sample rate @ 8bit resolution means:

The analog signal is sampled 48,000 times a second with 255 different possibilities of height.

Say the analog signal was at 1.0000001Volt. It would be truncated to the closest available value. You are losing information, but that's the price you pay for the power of signal processing and computing.

[KingCobra874]

Analog is to digital as organic is to synthetic.

[ZachWulf]

Yo dawg, we heard you like xeroxes....

[chrisLAchris]

Digital, the sexy word of the day ;) no wonder my wife loves u!

[andrewmtbfreak]

i just watched the thing on quantum programming and the bit about having any number between 0 and 1 is very simalar.if analouge computers could be made then the quantum computing could be made more useable.

[Quaaludedude714]

So Dial Up is Better ! :) QC

[IssacSir]

I likes it =)

So we ourselfs are in a way analog ^^ we get older and look older because everytime our cells regenerate they do it with "errors" so to say we are analog

XD so we should strive to get digital ; ) ...maybe..

[georgbernier]

@IssacSir man, you really got it. i totally agree with you. hahahahaha, we should be digital. 

[clancym1]

@IssacSir that is precisely what many geneticists believe is the reason for aging. seriously. almost word for word.

[ObC09]

@IssacSir Haha, that's a great way of looking at aging! Granpa's not senile he's just riddled with "errors"! I wonder if this means vampires (immortal ones) are genetically digital... O_O

[billlibong]

@ObC09 actually your right...as you age your DNA is making a copy of itself and losing some of the information after every copy

[MithranArkanere]

@IssacSir Nope. Our DNA is 'digital'. Instead 1 and 4, it has combinations of 4 bases. The problem is that the copy process is biochemical, and many factors may alter it, causing errors.

If instead having always 1 and always 0 an error may turn a 1 into a 0 and a 1 into a 0, even digital won't make always perfect copies.

[IssacSir]

@MithranArkanere You certainly have a point there our DNA is digital and thats necessary for heredity and works most of the time quite well.

But we ourselfs ,our cells are analog.

I already meantioned that our cells regenerate with errors and thats a cause for getting older and at one point the cells die, but not only that, our body cant "handle" "digital-cells" and thats a big problem with cancer cells .

Because Cancer cells dont regenerate with errors they have an almost unlimited "lifetime".

[MithranArkanere]

@IssacSir Our cells are not 'analog'. They are microscopic biochemical machines. They don't work with waves, they work with molecules.

Even our eyes are digital. We don't perceive wavelengths of light. We have cells that capture light as dots, and the the brain composes an image.

Even our brains are digital if you look at how neurons work. Short term memory has more information, and long term memory is 'compressed'.

We are as digital as our machines. No matter how you look at it.

[kevinyla]

@IssacSir

Our DNA is digital. The copying is also digital. It's called a misread. Even computer systems have a method of double checking.

Also, cancer sells have errors too. There's something else that causes cancer cells to be able to last longer than an average normal cell. I think Dr kaku actually addresses this topic else where. Like immortality of something.

[herbrantje]

@kevinyla

Indeed he does, but he states that cancer cells have no copying errors which is why they take over so radically.

[AdolphX]

@IssacSir wrong good sir, we are actually digital, the univierse itself its digital, as we are not composed by waves but particles, thats like the binary sistem, 0s and 1s. as for the why we get older is because of our genes, the younger we are the "longer" our genes are, as we grow older this genes start geting shorter and shorter, thats were the "errors" as we can call them get made =)

[herbrantje]

@AdolphX

Did heisenberg not proove that electrons are both particles and waves? depending on the observer? And zooming in even deeper on this, M-theory would suggest that everything is made up by vibrating strings or loops in which the frequency of the string or loop defines its character.

[AdolphX]

@herbrantje that is correct, then depending on the obvserver we are analog or digital...thats...confusing hehe, but the main reason why we get older is mainly our genes getting shorter everytime

[fizzlemanizzleable]

@IssacSir i aint' no zero and one

D:

[ckorweng1]

@IssacSir type 2 civilisation.

[Poketarist]

@IssacSir wow, i thought the same thing and i just saw your comment :)

[Trinivalts]

@IssacSir That's not the case as far as i've gotten to know. We supposedly lose teleomeres, that tie up the ends of dns's and when that is used up, only then there can be errors, & only one error can result in a dangerous mutation. (cancer, which is the disease of old age by that logic.)

[deeroks1]

the best explanation yet for me. thanks.
