In statistical theory, a pseudolikelihood is an approximation to the joint probability distribution of a collection of random variables. The practical use of this is that it can provide an approximation to the likelihood function of a set of observed data which may either provide a computationally simpler problem for estimation, or may provide a way of obtaining explicit estimates of model parameters. The pseudolikelihood approach was introduced by Julian Besag in the context of analysing data having spatial dependence. (Wikipedia).
Teach Astronomy - Pseudoscience
http://www.teachastronomy.com/ A pseudoscience is something that pretends to be scientific but is not. Science follows a rigorous method which relies on the sharing of data, the basis in observations, and the fact that any scientist can assert something, but it has to be supported by evid

Natural vs. Synthetic Vitamins
Anti-science mentality is prevalent in modern society. This is evidenced most clearly in a complete distrust of chemicals synthesized in a laboratory. But does the activity of a molecule depend whatsoever on the pathway from which it formed? Let's see why not. General Chemistry Tutorials:

What the heck is a Multiverse?
The idea of a multiverse (short for multiple universes) can seem absurd. After all, the definition of universe means everything, so what does it mean to have multiple universes? In this video, Fermilab’s Dr. Don Lincoln lists a couple possible definitions for a multiverse. The reality in
