- Over the weekend, children's author Madeleine L'Engle died at 88. Her most noted work, A Wrinkle in Time, is a story about a girl's journey across the universe in an effort to rescue both her father and the galaxy itself from the evil "Black Thing." The book, which dealt with heady (and un-kid-friendly) concepts like religion, theoretical mathematics and evil, took years to finally find a publisher due to its perceived weirdness. Since finally going into print in 1962, Wrinkle has sold millions of copies and remains a favorite read for young teens today.
One concept L'Engle explored in the book was tessering, a method whereby people could traverse great distances in the universe by "folding" space and time. Although they don't behave in exactly the way L'Engle describes, tesseracts do exist, and serve as important and elegant examples of multidimensional space.
An actual tesseract is best described as a four dimensional cube...and is kind of confusing. So, in memory of L'Engle, we met up with Physicist David Morgan who took a little time out of his day to talk tesseracts with the BPP. Put your measley three-dimensional brains to work on this one.
Thank you for such a well done little video. I love “A Wrinkle in Time” and I have always treasured mathematics like this.
My favorite book as a kid. I think I've read it 100 times. I still have a worn out copy of it. Excellent book. Rest in peace Madeline L'Engle.
I can't agree with your comments more. This was my absolute favorite childhood book. I got it for Christmas and read it in 3rd grade. I'm so sick that I never had a chance to go to a reading by this wonderful author.
Omgosh, THANK YOU for this!! It's incredible...what I've always wanted. Thank you thank you THANK YOU!!
Think of it this way: Imagine a 3-D cube. Now flatten it in your mind; imagine the depth of the cube shrinking until it resembles that drawing on the blackboard, where it's a cube that's just barely three dimensional. Let's call that a "flat cube". Now imagine a cube where each side of the 6 sides of the cube is a "flat cube". That's a tesseract.
Like he said, you can't fully wrap your mind around it.
My absolute favorite quote of all time is, “Mathematics is the alphabet with which God has written the universe.“ -Galileo Galilei
On a "Wrinkle in Time" I'm doing class work on it and i've watched the movie on it, and i never really thought a tesseract was a dimensional square, making the fourth dimension, and moving it around. But the thing is do we live in a 4th dimension, everything on earth is constantly moving..just like a tesseract. I'm guessing no matter what we'll always be in a tesseract.
Thanks for posting this. I love L'Engles books, and this is a very interesting video.
I don't think a tesseract really has anything to do with space/time travel like in the books. In the books a tesseract is supposed to be the fifth dimension while time is the fourth. They're wonderful books all the same, some of my favorites.
I appreciated the explanation about how the tesseract is constructed but I would like to know more about how this specifically relates to the time travel utilized in the book - and how this theory came about. If anyone had the answer, feel free to send me a message.
Thanks! Madeleine L'Engle forever!
Vibration between two different spaces that create a stable flow of energy. Two different vibrations in harmony that generate energy.
The fourth dimension is time, think of 3D space moving in a single direction. Here's how I do it: I look at a road full of cars, then I blink. After 2 seconds I open my eyes to look again and see what is different. The movement of the cars from the first time you were looking has moved along the 4th dimension into its new position. We are constantly moving. You can also do this with a picture but the real effect must be done with your eyes.
no. he said 4 spatial dimensions, not our (3d +1t ) = 4D spacetime. he is speaking of the 4th dimension of space as its hyperbolic to us.... you grasp some knowledge of using time as a dimension to walk through, but thats actually not how it is in the movie. its using a wormhole in a 4th spatial dimension as a bridge.
Hi there! Thanks for this fabulous, clear (sort of? ha ha) explanation of a tesseract... who could we contact about permission to use this film in our teaching video on A Wrinkle in Time?
I love this children's book. But how does l'Engle turn the tesseract into a wormhole? She even uses the verb to "tesser." I always thought the fourth dimension was time-space. But that doesn't necessarily describe a means to travel. Is that concept ever criticized in her novel? How does one describe the concept of a wormhole?
Why doesn’t someone draw the tesseract over and over again? That would look pretty
How did Paul get stuck in the third dimension somebody please riddle me that
Take two different crystals vibrating at different hertz. Where the harmonic waves cross energy is created. Sacred geometry. The key to both carbon based lifeforms and silicon based lifeforms. The key to life! That is called the flower of life.
we are weird combinations of trillions of vibrations of different harmonic series and planes based upon (phi) for our form of life's recursive geometry in our DNA up unto our fingers bone digit ratios, to the planet orbital layers and why the gas giants are further out as gas rises even in the vacuum, under the presence of a gravity well unto itsef, and also the cone of gravity our the suns plane of angular momentum. the gas giants locations are in proportion with the music of the spheres by pythagoras... or Ptah+Horus if you believe that part.
" We can't think in 4 dimensions, but we can easily do math in 4 dimensions". Mind blown.
Sadly we never will cope with this. That's the whole point of this video, to understand, that we cant understand it. Although i read an idea, that if we made 4D video games, our children might. I hope that day comes. And yes, that was a 5D cube, we saw, becouse it was rotating in the 4th dimension but needed time to do so, witch in this case is the 5th dimension.
@happymyster it is impossible to imagine the fourth dimension, but completely possible to think about it
finally at last somebody can evplain what a tesseract is althought it didnt explain how its related to madelin
awesome book I just started reading it and I"m soaked with it . Best book ever recommended from an actriz of the George Lopez show ,Maisela Lusha
exacly... i think there are videos that exllaon this better... When the 4th is time, the 4th is mani time lines. But who knows
Reminded me of a cell within a cell.
interlinked?
THAT IS SO COOL
Very interesting...I've read all of her books and could never fully grasp what the heck a tesseract was...lol
Okay, but he didn't relate it to the tesseract from the book at all. Does that mean her space hopping version is completely invalid, or was there some merit to it?

I don’t think anyone has fully understood what a tesseract is and what it can do..Our brightest minds, currently, are just scratching the surface. If there are those on Earth that do “get it” they aren’t open about it.
@@VivKittie32 ...it not being fuIIy understood aIIows us to experiment, and come to a better understanding within ourseIves...we step out of the preconceived ideas and become exceptional observers :)
Since it only takes three points to determine a 2 dimensional plain, why isn't the 2 dimension a triangle instead of a square?
It takes an infinite amount of 1 dimensional planes to create a 2 dimensional plane.
You make a good point. The fundamental shapes should be simplicies, from one perspective. Simplicies are triangular shapes with each point contributing to objects dimension. A 4 dimensional simplex has 5 points. A 3 dimensional simplex has 4 points: imaginge a triangle base pyramid. And a 2 dimensional simplex is a simple triangle.
There is another point of view in which the tesseract is more natural. This is when you consider the orthagonality of the dimensions. Each dimensional direction is at 90 degrees to each other dimensional axis. If you want to emphasize this aspect, you would use tessaracts, cubes, and squares.
Hi, it's Jonathan Moye
Is a point less than one dimension?
A line is an elongated line, or a point looked at horizontally instead of straight ahead.
The 3rd dimension, “a wrinkle in time” is talking about, is that 3rd cube, but only showing three sides, front, top and one side.

The cube u show is a 4d representation in 2d; top, bottom, two sides. A fifth dimension is space, not time. There is no time, just your position in space.
@AdamLore if what they say is true that we have 11 or 12, then there is a 13th, which can see the 12th as if it were our own 3d world compared to a 4d world
A structure with two harmonic signatures that generate huge amounts of energy? A trinity?
The 4D is a black hole/ worm hole is the easiest way to explain it
I don't agree with this theory, because the only thing of this tesseracts is just another cube and 4d explanation
lmao who else doing this for homework
LMAO HI
Yay, mathematics! Woo!
being 3 dimensional is so boring =[
Yeh, I'd rather be 2 dimensional.
Take two different cryst
Jim Martin so odd for a moment crust reminded me of Christ. Healing cryst, healing Christ, light to energy as in the transformation of Christ.
Jim Martin The Christ and the crust or anti christ?
