The cytoskeleton (composed of actin filaments, microtubules, and motor proteins) behaves as an active gel. It constantly remodels itself, driving cell division, muscle contraction, and intracellular streaming.
does exactly that.
: Framing problems through physical concepts like "momentum shifts," "friction," or "kinetic blocks" takes away the emotional shame often felt by clients. the+physics+of+living+amundson+pdf
The final sections deal with adapting to uncertainty and fostering a positive future outlook. : Framing problems through physical concepts like "momentum
In the other drawer, we place the alive : cells, hearts, minds, ecosystems. This is the domain of Biology. It has historically been viewed as messy, wet, and unpredictable. For centuries, biology was treated as a secondary science—a descriptive endeavor that studied the "soft" exceptions to the "hard" rules of physics. This is the domain of Biology
Forget ATP as magic fairy dust. Amundson breaks down the to explain why chemical bonds break and form. He introduces the concept of kT (Boltzmann constant times temperature) as the currency of the molecular world. A hydrogen bond (~5 kT) is strong enough to hold DNA together, but weak enough to unzip.
