Acrylic is the second new name for magic in paints. This is also a plastic-in-water. Solid acrylic you know as the beautiful, glasslike Plexiglas and Lucite. Are the contours rough or concealed? The first step is to cover the surface with a coat of paint, using your regular paint brush, or spray, or roller. Then, while the surface is still wet, take the dry stipple brush and energetically with short strokes drive the ends or the bristles into the wet paint. Be sure not to brush across. The result will be clusters of dots. Every few minutes wipe the brush with a cloth, to keep the bristle ends clean and dry.

When you plan with split complementary colors, you begin with a single reference color. Next, choose a color from either edge of the complementary color and use it. While the complementary color scheme is a little more obvious, this scheme can fail totally if you just use paler versions of your warm colors. By the same token, picking a a warm undertone for the main contrasting color and combining it with two cool tones will showcase the warm tone. Thinking skills (cognition): Thinking is a kind of "inner speech". We talk silently to ourselves to think through things and solve problems. Children in imaginative play begin to develop this skill through talking aloud and explaining everything that is happening in the game. (Think of the children playing in the "home corner" in your playschool and how they tell each other what to do and talk to the dolls and teddies). Slowly, as they become more practiced, this talking changes to become "inner speech" (they think it but don't say it out loud). This is a major foundation for developing thinking and reasoning skills. Treat yourself to a good lunch and forget the diet. It is amazing what some pizza or a good burger will do for the afternoon painting push. Lev Vygotsky was very well known and esteemed for his work in researching how children learn and the best methods to ensure that real learning actually happens. He said that "in play it is as though he [the child] were a head taller than himself. As in the focus of a magnifying glass, play contains all developmental tendencies in a condensed form; in play it is as though the child were trying to jump above the level of his normal behaviour." What he is saying here is that in play, a child uses and practices his skills, stretching himself into the next developmental stage.

General methods are often not adequate for accurate resolution of steep gradient phenomena; they usually introduce non-physical effects such as smearing of the solution or spurious oscillations. Since publication of Godunov’s order barrier theorem, which proved that linear methods cannot provide non-oscillatory solutions higher than first order (Godunov 1954, Godunov 1959), these difficulties have attracted a lot of attention and a number of techniques have been developed that largely overcome these problems. To avoid spurious or non-physical oscillations where shocks are present, schemes that exhibit a Total Variation Diminishing (TVD) characteristic are especially attractive. Two techniques that are proving to be particularly effective are MUSCL (Monotone Upstream-Centered Schemes for Conservation Laws) a flux/slope limiter method (van Leer 1979, Hirsch 1990, Tannehill 1997, Laney 1998, Toro 1999) and the WENO (Weighted Essentially Non-Oscillatory) method (Shu 1998, Shu 2009). Both methods are usually referred to as high resolution schemes (see diagram).
