What is four-dimensional space-time? Special Relativity: When describing a physical event in the theory of special relativity by Einstein, you need a reference frame that consists of a coordinate system and a clock. A coordinate system indicates or confines the position of an object in space. ...
Likewise, we can describe a point in 4-dimensional space with four numbers – x, y, z, and w – where the purple w-axis is at a right angle to the other regions; in other words, we can visualize 4 dimensionsby squishing it down to three. Plotting four dimensions in the xyzw coord...
What is four-dimensional space-time? (a) Suppose a meter stick made of steel and one made of invar (an alloy of iron and nickel) are the same length at 0^oC . What is their difference in length at 22.0^oC ? (b) Repeat the calculation fo ...
The focus here is on fourdimensionalism and different ways it can accommodate TEPs. I explore four different ways of dealing with TEPs within a fourdimensionalist framework. These are: (a) to make the objects that bear apparent TEPs temporally more extended or "chunky," while giving TEPs a ...
the inventors are rushing to add another dimension to the previously existing 3D items. According to Wikipedia, 4D is the extra dimension and a mathematical extension of the concept of three-dimensional or 3D space. A very common example is the Tesseract, which is the 4D version of the 3D ...
The Global Search for Educationbegins a five part series to discuss WHAT should students learn for the 21st century? We welcome Charles Fadel for Part 1: What is Four-Dimensional Education? Charles: It is an unpredictable world. What does it mean for Curriculum?
This something is a multidimensional hyperspace, sometimes called "the bulk." Within the bulk, as the theory goes, exists our four-dimensional universe (three physical dimensions, plus time), sitting on a membrane ("brane") within the bulk's higher-dimensional space. The number of dimensions ...
Imagine a piece of string being moved; the path it takes describes a two-dimensional plane. This is what happens when time is added to the one-dimensional strings operating in eight-dimensional space. The two-dimensional path is what is called a brane. This adds two additional dimensions to...
We wish to investigate spaces of dimension greater than three and in particular surfaces in 4-dimensional space. Such surfaces can be knotted. Our explorations include mathematical and visualization tools. Mathematically we focus on a particular example of visualization of the result of an energy flow...
The Global Search for Educationbegins a five part series to discuss WHAT should students learn for the 21st century? We welcome Charles Fadel for Part 1: What is Four-Dimensional Education? “Because of the vast amount of information that needs to be covered and the pressure of preparing for...
