1
Imagine that this folder is a dimensional plane.
2
Now, assuming that it is no height and no depth,
3
what would this mean?
4
It would mean that it's a one dimensional world.
5
So if, hypothetically, an organism was living inside of it,
6
it would only be able to move in a linear path forward and backwards in a straight line.
7
Now, if we go to the second dimension, we have two dimensions.
8
We have width and we have length.
9
So hypothetically, if an organism lived inside of here,
10
and it would be able to move up,
11
down, left, right, than anywhere else in between.
12
And a two-dimensional world is comprised of an infinite series of one-dimensional worlds stacked upon each other.
13
Just as our three-dimensional world,
14
which has depth and length and height,
15
is comprised of an infinite series of two-dimensional worlds.
16
So, now that I have stacked many folders upon each other,
17
we have three dimensions dimensions.
18
We have depth, we have length, and we have width.
19
Now what happens if you keep going on from here on out?
20
We would have a four dimensional world,
21
but what exactly is a fourth dimension?
22
In order to understand this,
23
we need to understand how dimensions are perceived.
24
We live in the three dimensional world,
25
but despite that, we actually view things to be two dimensionally.
26
Take a perfect sphere for example.
27
If you're looking at a sphere,
28
it looks just like a regular two dimensional circle.
29
The only way that you can tell is this actual sphere instead of a circle is
30
because of the hues of light down.
31
So just like in a two-dimensional world,
32
if an organism in the two-dimensional world was looking upon a circle,
33
the light would make it appear to be lighter at one end and darker in the middle.
34
Also, if an object is moving closer and farther away from you,
35
you don't actually perceive that it's getting closer and farther away.
36
You see that it's getting smaller or larger,
37
and then you assume that it's getting either farther away or closer.
38
But let's say that an object was to grow in perfectly equilibrium
39
so that it was growing at the same speed that it was shrinking as you move it farther away.
40
Then you would not be able to tell without any lights
41
or if there were details on the object that it's moving or growing at all.
42
You may have assumed that since we perceive things to be in two dimensions,
43
that a two-dimensional organism would see in one dimension.
44
So as we're watching this rubber band expand as it moves farther away from this little organism in the two-dimensional world,
45
it does not actually perceive anything is happening to it
46
because it's growing at the same speed that is moving farther their way.
47
But since we can actually see it from the three-dimensional world and perceive things to be in two dimensions,
48
we can see things for how they actually are.
49
The reason that the two-dimensional organism doesn't see things the way they really are is
50
because the two-dimensional organism sees things in one dimension,
51
just how we, three-dimensional creatures,
52
see things in two dimensions.
53
So in a way, we don't really see our world the way it truly is.
54
A four-dimensional creature, however, seeing our three-dimensional world in three dimensions would be able to see through things.
55
You'd be able to see absolutely everything,
56
just as we could see if there was several organisms spread along a 2D environment on your floor.
57
You'd be able to see inside houses.
58
You'd be able to see inside of people.
59
So if a two-dimensional world,
60
a flat surface, is just made of an infinite amount of lines,
61
then the 3D world is just made out of an infinite amount of planes.
62
So the 4D world, logically,
63
is made out of an infinite amount of 3D objects.
64
Though they're not just put together like you would like building blocks.
65
That's not how the 4D world is.
66
That would just be 3D again.
67
So in order to understand this,
68
we need to understand the logical progression of mathematics in our world.
69
Imagine that this connects piece represents the first dimension.
70
It's simply a straight line,
71
which is basically what the first dimension looks like.
72
And if you add three more of these straight lines
73
and connect them so that adjacent sides are perpendicular and opposite sides are parallel,
74
then you have the basic shape of the second dimension.
75
You have a square.
76
Now if you keep going from here,
77
and you add four- hide it so that there's a total of four squares,
78
and all adjacent sides are perpendicular,
79
and all opposite sides are parallel,
80
then you end up with, obviously, a cube.
81
So, if you tried to keep going from here,
82
and you would have a four-dimensional basic shape,
83
you would have what's called a tesseract.
84
Now, I cannot show you a tesseract,
85
but you need to understand that it's basically four cubes
86
that are within each other that have all adjacent sides perpendicular and all opposite sides parallel.
87
Yet there are four lines connecting to each vertex.
88
So, a tesseract would look somewhat like this picture.
89
Now that's not exactly what it looks like
90
because this is a two-dimensional depiction and obviously not all the lines are straight
91
So I cannot show you what a tesseract actually looks like because we cannot perceive things in the third dimension
92
You cannot even imagine what a tesseract looks like you cannot
93
Physically you cannot in your mind picture the fourth dimension
94
or a fourth dimensional shape And you can keep going on from the fourth dimension even.
95
You can go to the fifth dimension,
96
the sixth dimension, the 71st dimension, it doesn't matter.
97
Theoretically, there are an infinite amount of spatial dimensions.
98
A common misconception of the fourth dimension is that the fourth dimension is time.
99
Now, while some argue that by going forward and backwards in time,
100
if you move forward the same distance and backwards the same,
101
then you would end up in the same place you started,
102
just like in the fourth dimension.
103
And while that may seem logical,
104
if you think about it,
105
it really doesn't make sense.
106
If you imply that the fourth dimension is actually time,
107
well, first of all, time is not spatial.
108
There's a difference between space and time, quite obviously.
109
And assuming that all dimensions are according to a pattern,
110
then that doesn't really make sense either.
111
Because saying the fourth dimension is time,
112
every dimension has time in it.
113
So that would mean that the fourth dimension is special in some way,
114
which doesn't really make any sense.
115
Another reason this doesn't make sense is that we very,
116
very, very slightly travel through time whenever we move due to the distance that light takes to get to our body.
117
If a group of astronauts were to get in a spaceship and they were to go very,
118
very, very close to the speed of light,
119
then they would, and they went around in this impossible,
120
nearly the speed of light spaceship for a few months,
121
and then afterwards they returned to Earth.
122
They would find that Earth had actually progressed a few years,
123
so they had moved forward in time by moving that quickly.
124
Another interesting concept involving the fourth dimension is that many physicists,
125
and even mathematicians, may say that the dimensions are very,
126
very slightly curved, because if you really think about it,
127
nothing can be truly, absolutely infinite infinite.
128
So imagine that the first dimension,
129
the line, is just very,
130
very slightly curved so that after a very long time it will end up creating a circle.
131
So as suggest by many physicists,
132
if you keep going in the same direction then you will end up where you are,
133
where you started after a very,
134
very long amount of time obviously.
135
And the same thing would happen to the second dimension
136
if it's just a square and then you extend it very very slightly in a curve
137
and it will eventually make a sphere
138
and the same thing happens in our dimension except it will form a very very slightly curved um third dimension
139
which will form a four-dimensional universe basically so what this kind of means is
140
that our three-dimensional world is within a four-dimensional world,
141
and the four-dimensional world is within a fifth-dimensional world, and so on.
142
Now, I did say that nothing can be truly infinite,
143
but if this is true,
144
and a dimension is really within another dimension within another dimension within another dimension,
145
then I'm implying that there's an infinite amount of dimensions,
146
which is the only problem I really have with this theory.
147
I'm not sure if it ever stops,
148
or if infinity is really even possible.
149
We don't know that.
150
it.

Perché esercitarsi a parlare con questo video?

Praticare la comunicazione orale è essenziale per migliorare le proprie abilità linguistiche in inglese. Questo video, presentato da uno studente delle scuole superiori, offre un esempio chiaro e coinvolgente di come spiegare concetti complessi come le dimensioni. Utilizzando un linguaggio semplice e diretto, il relatore invita gli spettatori a riflettere su idee astratte, stimolando così la curiosità e il desiderio di approfondire la lingua. Esercitarsi a parlare seguendo questo video permette di sfruttare il metodo del shadowing in inglese, dove gli studenti possono ripetere e imitare le frasi per migliorare la propria pronuncia e fluidità. Attraverso la pratica costante del shadow speech, è possibile assimilare non solo il lessico, ma anche le espressioni e le intonazioni naturali dell'inglese.

Grammatica e Espressioni nel Contesto

Nel video, il relatore utilizza diverse strutture grammaticali e espressioni che possono essere utili per gli studenti di inglese. Ecco alcune chiavi di lettura:

  • Condizionali ipotetici: L'uso di frasi come “se un organismo vivesse qui” dimostra come formulare ipotesi riguardo situazioni impossibili. Questa struttura è utile per esprimere pensieri o concetti astratti.
  • Descrizioni spaziali: La distinzione tra ‘larghezza’, ‘lunghezza’ e ‘profondità’ mostra come usare aggettivi per descrivere le dimensioni e gli spazi in inglese, un passaggio cruciale per chi vuole migliorare la propria capacità di esprimersi.
  • Vocaboli tecnici: Parole come “dimensionale” e “organismo” sono esempi di lessico che arricchisce il vocabolario degli studenti, permettendo loro di esprimere idee complesse.

Trappole Comuni di Pronuncia

Quando si parla di argomenti scientifici, è facile imbattersi in parole e concetti che possono risultare difficili da pronunciare. Per migliorare la pronuncia inglese, è importante prestare attenzione a termini come:

  • Dimensionale: può essere complicato per chi non ha familiarità con suoni come “di-” combinato con “men-”.
  • Organismo: la pronuncia corretta della “g” e della “n” è fondamentale per evitare malintesi.
  • Sfera: notare l'accento sulla seconda sillaba, che può essere facile da trascurare.

Utilizzando tecniche come il shadowspeaks, gli studenti possono davvero affinare il loro orecchio alle sfumature della lingua e perfezionare la loro pronuncia. Iniziare a utilizzare lo shadow speak in contesti pratici, come quello del video, può rendere l'apprendimento dell'inglese non solo più efficace, ma anche più divertente.

Cos'è la tecnica dello Shadowing?

Shadowing è una tecnica di apprendimento delle lingue supportata da studi scientifici, originariamente sviluppata per la formazione dei traduttori professionisti e resa popolare dal poliglotta Dr. Alexander Arguelles. Il metodo è semplice ma potente: ascolti un audio in inglese di madrelingua e lo ripeti immediatamente ad alta voce — come un'ombra che segue il parlante con un ritardo di solo 1–2 secondi. A differenza dell'ascolto passivo o degli esercizi di grammatica, lo shadowing costringe il tuo cervello e i muscoli della bocca a elaborare e riprodurre simultaneamente i modelli di discorso reale. La ricerca dimostra che migliora significativamente la precisione della pronuncia, l'intonazione, il ritmo, il discorso connesso, la comprensione dell'ascolto e la fluidità del parlato — rendendolo uno dei metodi più efficaci per la preparazione alla prova di speaking dell'IELTS e per la comunicazione reale in inglese.
