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.

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.

Yeah, a dimension refers to any parameter of a body that is associated with a particular state of a body. That means if I change any parameter that causes a change in the object, then that parameter is a dimension. In physics, if you go down to the very basics, you can change only 4 things, 3 positions and 1 time. But according to string theory the strings also have additional states that are not related to these 4 dimensions and thus they have some additional dimensions.

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. :)

So, that means that once 4d printing is in a stage that 3d printing was about 10 years ago, Stratasys is going to patent and sue anyone who uses 4d printing without paying them royalties! Shame on you. You are such a hypocrite. These kind of laws need to change. Stratasys should not be able to patent something they do not even know how to make. At this point I could go and file a patent that says I own the right to a hologram that involves light. I don't know how to make it, but I have a patent. That's ridiculous and absurd. I really feel bad for Bre Petis (sort of), he had this company with so much potential and a maker following and then he sold out to Stratasys. makerbot then went on the become closed source and closed hardware, dare I mention the makerbot 5th gen or Z18?

Manufacturing and subtractive machining is far faster than 3D printing, and with mass production, the machining time sets the price. As seen in this video, the presentation showed up to a 150x increase in speed of the video in order for the structures to take shape. Overcoming this is the real challenge and very impractical at this point, since 3D printing itself is extremely slow. How about we get 3D printing up to speed and THEN worry about 4D?

Three spacial dimensions + one time dimension = four overall dimensions.

Self assembly and self organizing is not the function of a printer, so it is silly to call it 4D printing. I can already print a clock with moving parts, but does the fact that the clock changes its state over time make it a 4D print? No. 3D printers just product static parts, and what those parts do after they have been printed is not a function of the printer itself. Nature is already doing self assembly and the field of nano technology has been studying this kind of thing for decades. Trying to put a new nonsensical label on an old concept does not make it an "emerging" technology.

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.

" i have figured a way to start a fire by friction ... we rub these two pieces of wood together long enough and a fire will begin "... judging from these comments one can imagine the response . There is a reason why the pioneers, the brave ones ... the ones who truly believe against all odds .. even through ridicule ... have been the ones to open windows to worlds we could not have ever been able to imagine / comprehend / foresee !!! IT IS ONLY , because of those few .. we humans continue to prosper and grow and enjoy modern life as we know it . For the pioneers around us today ... i am so grateful , for they continue to create and " blow our minds " with building an awe - inspiring future , for all to benefit , that is truly ... out of this world .

definitely, but you can't deny that its a cool product, and technically their end product is 4d, but only if you count time as a separate dimension, although im fairly sure its actually just an extension of space, but we wont go into that here

Actually, it is very interesting (setting aside the fact that this is not 4D printing and that he is just making reassembling, not self-assembling materials). Imagine that we could resemble the protein function on a mayor scale. However I think that it is not just a matter of positive a negative charges, it must be more complex. For example, proteins (and some other molecules) have functions (more or less specific) which are determined by its structure and its composition (the amino acid content). Amino acids have different properties, some of which contributes to the assembly of the structure (which also depends on environmental interactions) and others to the function of the protein. However, even though there are non polar amino acids that make the protein to fold hydrophobicaly, some proteins need help from other proteins and modifications to fold as a completely functional molecule.

Umm. The Navy already has these installed on their ships. When the capsule hits the water it bursts open and inflates into a covered life raft able to hold 25 crew members.

I'd say that we can already "print" medicine. We can already synthesize compounds for medicines fairly easily so I don't think a "printer" would actually be of much worth.

It's still 3D printing. When you say 4D that already means something other than a 3D shape or environment. Like time for example.

I nearly died inside when he referred to a piece of paper as a 2d object. My middle finger has 17.6 dimensions of FUCK OFF attached to it. It does, because I said it does.

In as much as 3D printing isn't printing at all, since printing relates solely to words, symbols, etc. in paper form, and the art and act thereof. "3D fabrication" didn't have that layman's ring to it, and it somewhat approximated the process of printing, so they slapped that word in there. "4D" in this sense seems to relate to the fact that 3-dimensional materials self-assemble from their original state over space-time, hence 4-dimensional.
