Scalar, a physical quantity that is completely described by its magnitude; examples of scalars are volume, density, speed, energy, mass, and time. Other quantities,

This rescaling does not affect the multiplicity of the tubes. Applying again, we see morally that the multiplicity of the rescaled tubes, and hence the thin tubes inside , should be . We now observe that the multiplicity of the full collection of thin tubes should morally obey the ...

Homework studies as an example of the overall process of meta-analyses, so there is plenty of material. In a key example, he describes a study of five meta-analyses that capture 161 separate studies involving over 100,000 students as having an effect size d= 0.29. What does this mean?
This is what we mean. 4×1 gives me this little area, 4×1 is 4, 3×1 is 3, 4×5 will be 20, 3×5 is 15, we divided this into four separate pieces and when we add them up, we will get 42. 4+3 is 7, 20 is 27, and 15 more is 42. ...
Base 10 is, as you indicate, provincial and ultimately meaningless. Shannon’s information theory again. Base 2 is sufficient for all information (and hence all mathematics). Base 10 doesn’t mean any more than French or English or Russian does with regard to the actual reality of cats or ...
as if facts from authority in schools it controls by law, and through the MSM, using the money they take from us by law to deceive us, where those being taught do not yet have the formation to validate received wisdom for themselves, so can be deceived hence manipulated by such ...
The topic of this paper is mathematical modelling or—as it is often, more broadly, called—applications and modelling. This has been an important topic in mathematics education during the last few decades, beginning with Pollak’s survey lecture (New...
