Osmosis and diffusion (Chandler, James)

Diffusion and Osmosis

1. Review the concept of heat and the processes of diffusion and osmosis. Learn the factors that affect the rate of diffusion. 2. Observe Brownian motion and relate this observation to the concept of heat energy. 3. Measure the speed of diffusion of dyes in a gel, and the speed of diffusion of gases in air. Relate the speed of diffusion to molecular mass and medium. 4. Investigate the process o...

Osmosis and Diffusion Conceptual Assessment

Biology student mastery regarding the mechanisms of diffusion and osmosis is difficult to achieve. To monitor comprehension of these processes among students at a large public university, we developed and validated an 18-item Osmosis and Diffusion Conceptual Assessment (ODCA). This assessment includes two-tiered items, some adopted or modified from the previously published Diffusion and Osmosis...

Autobiography of David Chandler.

I was born the younger of my parents’ two children, on October 15, 1944, at Brooklyn Jewish Hospital, in New York. Except for two years when I was five and six years old, I spent my formative years in Great Neck, a north shore Long Island suburb of New York City, where I benefited from material comforts, excellent schools, and abundant opportunities for cultural and recreational activities. My ...

Wright, Okasha and Chandler on transmission failure

ABSTRACT Crispin Wright has given an explanation of how a first time warrant can fall short of transmitting across a known entailment. Formal epistemologists have struggled to turn Wright’s informal explanation into cogent Bayesian reasoning. In this paper, I analyse two Bayesian models of Wright’s account respectively proposed by Samir Okasha and Jake Chandler. I argue that both formalizations...
