16:14 "but computer scientists time flows downwards. I really don't know why." Early CRT monitors (which were modified TV screens) drew the image on the screen in lines from left to right and starting with the top line moving to the bottom. All pixels were stored in video memory in the way they are drawn on the screen. So if you wanted to draw something on the screen (by modifying video memory), you had to use the co-ordinate with the Y-axis going downwards. Though we do not use CRT monitors anymore, this convention is still widely used in CS.
Also, a program starts at the top and runs downward as lines are executed. If I remember correctly. Until a command is read to go somewhere anyways. I only learned BASIC lol! I really should have stuck with it.
Thank you good sir, I am so happy this popped up into the algorithm on UA-cam for my home feed… You just got another subscriber, bell on and everything
Time flows downwards in computer science probably because code (with no jumps) executes downwards line by line. Upwards in cosmology maybe because of events emerging out of the big bang (a gravity well, with convention on earth being gravity source is down?).
i play the guitar (right handed) so my nails are too long to text on my right hand, lots of people have assumed i'm left handed because when i text i move the phone with my right hand but hit the keys with my left, and although it's not a lot of things, i do a few things "left-handed" as it's easier. "handed-ness" is more interesting now lera has brought historical influences. cardinal directions is another one, in the UK road layout is historical, whenever people and horses went, that's where the road would go, in the states though most roads are east-west or north-south, so i notice in movies and games people refer to "heading north" or "they're on the east side" whereas i would have to stop and think about which direction was which. brilliant discussion, the approach from lingustics to the "hard problem of consciousness" is much more palatable, and definsatley not as "woo" as some. lera is brilliant, i've watched her TED talk (years ago) and some of her other presentations, this is a really interesting area, and also a great way to catalogue and record language as so many are dying - by the moment!
If I ‘bring ‘ something forward , it’s towards me . If I ‘put ‘ something forward it’s in the future . Isn’t it about the accuracy of what we say ? Our minds work so fast sometimes , that we miss the important things
16:20 I think the implements are why computer scientists think of time moving from top to bottom. Old printers would print one row, move the paper up, print another row below the first and thus the early was always on top of the latter.
Many years ago, after reading the book "Men of Mathematics," it occurred to me that being born into the French language may offer some advantage towards being a mathematician. Obviously speaking English or German is not much of a handicap, but there does seem to be a lot of remarkable French mathematicians. I would like to hear from an expert about this hypothesis.
51:05 "you've said some word, understood some words and feel pretty good, and like, achievement unlocked..." Not only have understood Spanish in this moment but also a new generation of English. 16:00 It would be interesting to know the historic percentage of the programming market that originates out of China.
27:23 Upriver/downriver: that’s how Montrealers organize space. Down = towards the St.Lawrence (even if locally it’s uphill) = “south” (even if in reality it’s SE or even ESE); and Up = away from the St. Lawrence (even if you’re going downhill towards the Prairie river) = “north” (even if it’s really NW or WNW). And then East-West is actually parallel to the St. Lawrence, which sometimes flows NNE. Visitors are amused or bemused seeing the sun rise in the south. ⚜️🇨🇦
If time didn't have an arrow, every point in spacetime would be a massive collision zone. Try crossing the intersection without an arrow of time. Time is absolutely intrinsically intertwined with reality.
Lera B is so natural and smooth like mist. Very open minded. She mentioned Time comes with very first cell... zygote...But space ...the moment you start to perceive. Sean's space-time gets little disappointment there.. Down the road we will learn both are just the manufacture of mind. QFT already proved it.
I had heard of the Russian distinction between blue and light blue, but no one seems to talk about the American distinction between red and light red (AKA pink).
If I bring something forward , it’s towards me . If I put something forward it’s away from me . It’s easy not to get words right at speed . Am I right ?
tldr; Sean: so my positive associations of reality are only consistent in reference to myself? Lera: that’s right bucko and it’s why you felt the need to tell me.
I was surprised regarding the Zero Chomsky reference as well. Think the awkward moment after the Sapir-Whorf mention resulted in the pass over in silence.
If time travel is possible, time has to be n-dimensional. At present, it is true that the so-and-sos won the national Thingball championship. If I go back in time to change it, then it's not true that the So-and-Sos won. But in the past, it was true that they won. That is, in the past, the past was different than it is now. If I know that in the future, the Thingball champions will be the Thingamajigs, but I travel back in time to prevent their head coach from being born, then it is no longer true that the Thingamgajigs will win. But in the past, it was true that in the future, the Thingamajigs will win. I think this holds true even if time travel to the past is limited to going back to the spacetime location of one end of a wormhole. Like we built it on Thursday, so we can't ever go back prior to that date. But as long as we can go back to the date the wormhole was opened, time has to be at least two-dimensional.
To me it's pretty obvious why languages have categories of gender and not of height, weight, color or wathever. For starter, sex is pretty much a binary, with very few exceptions, while most other traits tend to vary along a smooth continuum. Furthermore, sex correlates with all sorts of important traits, such as reproductive compatibility, physical size and strenght, personality and social role, while most other traits usually vary independently. Then again, if it was arbitrary, cultural evolution wouldn't have converged on it.
Thank you Sean for keeping the content coming especially in a time like this.
I could listen to these two discuss virtually any topic! Great orators.

The relationship between language and thought is beautifully shown in the novel "1984". I highly recommend it.

Great recording quality! Keep it up Sean! To Infinity & Beyond!
It's a little too good in her case, I keep hearing her lips smack.

Yesss! Something to take me awaaayyy
Hi Sean. Please have David Deutsch on your podcast.
51:05 "you've said some word, understood some words and feel pretty good, and like, achievement unlocked..." Not only have understood Spanish in this moment but also a new generation of English. 16:00 It would be interesting to know the historic percentage of the programming market that originates out of China.

Smells are a powerful context for recalling memories 👃🏽😖😋😝
Great discussion!
I have a hard crush on Lera. She is amazing.
If I bring something forward , it’s towards me . If I put something forward it’s away from me . It’s easy not to get words right at speed . Am I right ?
The real question is are you left? ;)
Just watched the first class. 👍👍
When we think, we think with language and words, But what or how do the deaf people think ?.
Love it.
I would love to make translation to Hebrew if you teach me how
tldr;
Sean: so my positive associations of reality are only consistent in reference to myself?
Lera: that’s right bucko and it’s why you felt the need to tell me.
Someone should count how many times ’time’ is said in this episode.
The theme song got no groove.
Please bring Donald Hoffman in your circle.
Countdown to Wittgenstein being mentioned but not Whitehead
59:12 there it is. But where is Whitehead? I thought this podcast was about time.
I haven't listened to the podcast yet but I predict the words "Noam Chomsky" will be spoken at least twice.
@Laura i suppose this could be the first time I was wrong
@The Cave Explorer I failed

in re Sapir-Whorf hypothesis - it's pretty much been abandoned by the 1990's en.wikipedia.org/wiki/Linguistic_relativity
Offer stands Sean, first Jesus, then all the secrets of time and QFT.
Are you offering answers to these mysteries?

Qualia
First lol
Great discussion!!!
