Here's a question for a physics student to solve on the Lorenz attractor:

Consider the Lorenz system given by the differential equations:

dx/dt = a(y - x)
dy/dt = x(b - z) - y
dz/dt = xy - cz

where a, b, and c are constants. Given the initial conditions x(0) = y(0) = z(0) = 1, determine the values of a, b, and c such that the orbit of this system exhibits chaotic behavior. Then, plot the Lorenz attractor for these values using a numerical integration method.
