What is the difference between ferroelectric and ferromagnetic material?
What is the difference between ferroelectric and ferromagnetic material? Let us start with the basic definition; a ferroelectric is defined to be a material with a spontaneous electric polarization that is switchable by an applied electric field. Likewise, a ferromagnet has a spontaneous mag- netization that can be reoriented by an external magnetic field. Why […]
Can I send my dead body into space?
Can I send my dead body into space? Space burial is the launching of samples of cremated remains into space. Suborbital flights briefly fly ashes into space then return to Earth where they can be recovered. Small samples of remains are launched to minimize the cost of launching mass into space, thereby making such services […]

What does error propagation tell you?
What does error propagation tell you? Propagation of Error (or Propagation of Uncertainty) is defined as the effects on a function by a variable’s uncertainty. It is a calculus derived statistical calculation designed to combine uncertainties from multiple variables, in order to provide an accurate measurement of uncertainty. How do you add up errors? When […]
