4D printing is a good idea. That's taking scam to the next level. "Didn't receive our product? Well, did you look in the fourth dimention?" We don't even have 3D-printers yet, much less 4D.
Yavuz Ekim Bovkır oh god, mine does the same thing. I knew there was something sketchy going on here. My cables are attempting to create themselves in 4d.
The first thing that popped into my mind was a space ship loaded with millimeter thick sheets that when laid out on the Moon, Mars or in space could, when activated transform themselves into habitable structures.
It seems people are confusing 4 dimensions with the proposed "4th dimension." You can program 2 dimensional arrays... 3 dimensional arrays... OR TEN dimensional arrays. You can even program 500 dimensional arrays. That must blow some of your minds.
+sentdex Arrays really aren't hard to understand when you get down to it from a simple computer science standpoint. A 1 dimensional array is an array, a "single line" of elements. A 2d array is an ARRAY containing an Array. That basically every element of the first 1D array, contains another 1D array. Same process continues. A 3d array is an array containing an array which in turn contains the final array. Anything beyond 3D/4D is hard to visualize or impossible, yes. But you basically extend the concept of arrays containing arrays. Not really mind blowing, just a simple concept.
This guy is like me when I was in high school turning in an essay. I had a great title with neat font, lots of colors, neat transparent folder to tuck my essay into but then I get a D+ for content and not citing sources.
Those two problems actually can be solved easily, if anyone had taught you how. 1) Any time you are doing student or professional reading, key in or write out the interesting quotes along with the citation. 2) Maintain an ongoing bibliography of stuff you are reading. Then when you go for your degree or graduated degree you will already have 2/3 of the classwork already completed. Academic papers average 3 quotes per page. 3) START you essay by selecting a string of quotes that flow from one to the next harmoniously before you ever add a word of your own. 5). Dump your ideas into those containers, and you have the problems managed. You had the ideas all the time. Nobody had taught you a method/of rocesd for organizing and displaying them. The challenge when writing an essay is that you have to have a process for excluding infinity. The problem isn't getting enough to say but in figuring out what to exclude. 4). Learn 'rhetorical modes.'. The complete list of them included 9. Write the introduction last as a summary of what you have written and shape the summary as a definition paragraph or section. Write the conclusion as a persuasive paragraph or section. In a thesis it dissertation, include a section/chapter in each rhetorical mode in order to get the required length, unless some other structure becomes obvious to you.
I shared this to my oral expression students as a counter-example of a good presentation. This guy talks about a fascinating subject, but exhibits such stoicism and lack of passion with regards to his presentation that it feels like he lost the bet on "who will do the presenting"
jean-gobert de coster He must have had a bet going with his friends about how many times he could use "this is" in 40 seconds. 6 times probably would win that bet. One of the worst presentations, and presenter, that I've seen.
I think it depends on your background. If you are engineering/handyman based this is quite interesting because you are going through concepts in your mind and the possibilities they entail.
The best lecture. The illustration from 0D (quantum dots) - 4D (multiphase materials).It has got an application in modeling of Nanostructure, proteins, Biochips, Microchips, and bioelectroics. Thanks!
I can see this being used to manufacture emergency rafts for ships. You could have a whole fleet of folded rafts that are compact to store and take their shape when in contact with water.
Reminds me of The Diamond Age v Hackworth's chevalier. It printed on a small public "3d printer" (that word had not yet been coined when the book was written), and unfolded into a mechanical horse.
Thank you! This is not very widely-known information, and it's refreshing to see it stated so clearly. There's a lot of confusion about this all over youtube. I think there are more comments on this video about the presenter's interpretation of "dimensions" than about the actual technology he's talking about. Simply put, he's talking about printing objects using all four dimensions, the three spacial dimensions AND the time dimension. Quite interesting, really.
Studying the atomic bonding infrastructure when you bend a pipe what is the change of the atomic structure in the effected area where was the force or heat or tharmal energy was implied.
I seems to me that the biggest problem of such structures is that you need energy supply throughout the structure and in the case of self correcting structures you practically need abundance of it. Would explain why most "self-assembling" structures are on a nano scale.
One major obstacle I'm curious to see how they're going to overcome is how to control these transformations more. For example, the string seemed to transform from straight string to MIT with a touch, and keeping it at the MIT form seemed simple enough but what if one wanted to keep it in its string form?
Using 4D to describe this does two things; allows for a different take on the concept and also using the debate to draw attention to the new concept. Nice presentation.
Minutephysic's channel did a great video on dimensions. Basically, what they said was that a dimension is simply a parameter with which matter can be described. 1D, 2D, 3D and 4D simply describe the numbers of parameters matter has, but none of them specifically refer to any parameter. For example everything in our universe consists of 3 spacial dimensions and 1 time dimension (pretty much). Time isn't THE 4th dimension, but it is one of the four parameters of a 4D system. Hope that helps. :)
I used to do the same thing with the paper casing of a straw. Scrunch it into an accordion shape, pull it off the straw and put a drop of water on it and BAM! I would of done a Ted Talk for a fraction of his pay!
Very Cool. 4D printing is awesome. Heat changes water changed it cold changes it. That is the future. I Love TED talks. the guy was like a robot though he didn't have a lot of passion. It was a lot of good science but no passion still good though. People want passion when they see something, most anyway. Very to the point and right on with the information that's also important. I love the Talk.
he raises a valid point. before the candle maker could learn to make light bulbs, here they would learn the new job of creating self replicating objects, a job they would lose after the first one was made.
Brilliant but....pipelines - so would the pipe diameter increase with flow demand? Problems - clashes with other services like electricity or sewerage after expansion, weaker pipe due to expansion but increase in forces due to flow increase. Flow is dependant on the storm intensity and sometimes pit inlet surcharge is intentional for stormwater design, for example a q100 (1 in 100 year storm event), where hydrology becomes more important than hydraulics. Would the pipe attempt to correct itself outside of design parameters? From a geotechnical standpoint how would this effect topography? What happens to the extra volume of dirt once a pipe increases in diameter? How would an increase in pipe size upstream effect smaller downstream pipes given the variance of rainfall within different catchment areas? If constructed in upper parts of the catchments, the entire downstream would also need replacing (catchments are considered during design for both major and minor stormwater events), and pipe sizing is well thought out and crucial to avoid property damage, flooding and personal injuries. Water pipelines - always under pressure (hydraulic grade line is higher than top of pipe and does not rely on gravity). If pipe size increases, so does volume and capacity - however, incresing pipe diameter decreases in a lower pressure in the system that will not only effect both commercial and residential property water supply but also could reduce pressure to hydrants the is crucial in emergency situations for fire fighters. Food for thought anyways.
4-D printing can be more than creating a new way of production. The idea behind is that you can take multi-material 3D printing so you can deposit multiple materials and you add a new capability which is transformed right out of the bed. The parts can transform from one shape to another shape directly on their own.
I wonder how all of these great minds can organize themselves and form teams that work together to bring something new to the world.. like.. how is it even done?..
I have a hunch that it's not "little" energy as I would assume it to be quite inefficient (working with random forces or energy transferred through the whole surface).
7:20 starting the presentation i just imagine a pipe for the exhaust of cars that adapts to heat and airflow, changing from straight pipe to helix, or the x pattern to h pattern it woud make more eficiient all kind of ICE cars
i think he is speaking of 4D as time, and he is "printing" not just for "one" time but he is designing stuff with shapes over an interval of time, in some sense printing in 4D
I don't know what everyone has with additional space dimensions, we use tri-axial system to mesure objects so we have 3D world (sometimes it is needed to add fourth dimension the "time"). It is just an perception and it's not written in stone that we must use it. The reality is more like chaos of particles with vector and speed. But it is not a chaos, each action has corresponding reaction, and even every photon moove affects each surrounding particle and that creates the white noise of quantum mechanics, whitch is not random at all, we just can't see trough and when we try to we are projecting our perception into the quantum world that we see.
It would be cool if there were a material that could change it's Young's Modulus based off some transient input. Kinda like piezocrystals, but with the change being permanent.
there are different types of dimensions. the 4th dimension is often referred to as time because it's "a" fourth that we commonly encounter. the 4th spacial dimension however is not time.
Reminds me of Ancient Greece philosophers reading someone speak like that, and that last line reminds me of Ancient Roman stories, haha. That is an insane concept, and one that really leads to many questions. How many people would still contribute to bringing society forward? How many would just reproduce? How many would degrade the quality of society? What would be the balance? The religious right should be supporting it to have more time dedicating themselves to their religions.
If you consider time a dimension, an object that changes shape over time is 4D. However, using this definition, many of the objects we normally consider 3D are in fact 4D.
Stick with the example of plumbing. Notice anything familiar about the 'pipes' at 7:22? That's how the esophagus and intestines work. It is more complex to design in the beginning, but is more resilient and requires less maintenance over time.
Can titanium change shapes at will when you add a bit of water, heat or sound? Can entire buildings build themselves? Can water pipes expand and contract at will depending on how much water is flowing through? But you're right this definitely isn't anything new.
