research

Yang Wei wants to reform attitudes towards research ethics at Zhejiang University and across the country.

Yang Wei has an easy smile and a carefree, even distracted, air — but he takes such a solemn approach to life that his wife sometimes tells him to relax. “I take everything seriously,” he says.

Attached are some (hand-written) observations on wanting to do continuum mechanics when mass is not conserved for fixed sets of particles of the body (so, situations transcending the rocket-losing-mass type). I feel (un)comfortable with these observations, depending upon the day I think about such things.

Study on the properties of inhomogeneous media plays a central role throughout the history of physics, e.g.

Possion’s theory on magnetism of composites, Faraday’s dielectric model of composites, Maxwell’s and later

Rayleigh’s work on conductivity of composites, and Einstein’s thesis on viscosity of fluid-particle media. As

a special branch of this field, percolation research on phase transition and critical phenomena was originated

with lattice percolation theories in 1950s [1]. The idealization of a lattice structure is convenient for analytical
