The cooking of a healthy breakfast moves from parent-child bonding to an eloquent conversation about energy, the growth of plants, and the miraculous ways the sun's light nourishes us all. It began with the sun, Who showers the earthWith heat and light--Tiny packets of energy. How does a home-cooked breakfast give a little girl the energy she needs for a brand-new day? In gently expressive language, her mother takes readers on a journey into the earth where sleepy seeds are tickled awake and grow into golden oats; into blueberry patches, where green leaves break apart water and air to build sweet sugar; and into a pasture where sun becomes grass, becomes cow, becomes milk.Author Laura Alary's free verse breaks big ideas into child-sized pieces, making Sun in My Tummy an accessible introduction to the concepts of matter and energy, and how the sun's light becomes fuel for our bodies through the food we eat. Andrea Blinick's mixed-media illustrations pair the cozy and homelike with the g

Differential Equations with Mathematica, Fifth Edition uses the fundamental concepts of the popular platform to solve (analytically, numerically, and/or graphically) differential equations of interest to students, instructors, and scientists. Mathematica's diversity makes it particularly well suited to performing calculations encountered when solving many ordinary and partial differential equations. In some cases, Mathematica's built-in functions can immediately solve a differential equation by providing an explicit, implicit, or numerical solution. In other cases, Mathematica can be used to perform the calculations encountered when solving a differential equation. Because one goal of elementary differential equations courses is to introduce students to basic methods and algorithms so that they gain proficiency in them, nearly every topic covered this book introduces basic commands, also including typical examples of their application. A study of differential equations relies on concep

This Element looks at the problem of inter-translation between mathematical realism and anti-realism and argues that so far as realism is inter-translatable with anti-realism, there is a burden on the realist to show how her posited reality differs from that of the anti-realist. It also argues that an effective defence of just such a difference needs a commitment to the independence of mathematical reality, which in turn involves a commitment to the ontological access problem – the problem of how knowable mathematical truths are identifiable with a reality independent of us as knowers. Specifically, if the only access problem acknowledged is the epistemological problem – i.e. the problem of how we come to know mathematical truths – then nothing is gained by the realist notion of an independent reality and in effect, nothing distinguishes realism from anti-realism in mathematics.
