Ma Lin encouraged these people to draw all the organisms they saw under the microscope and record the phenomena they observed.
He also encouraged them to grind astronomical telescopes to observe the moon and various celestial bodies near Pin Star.
"The astronomical sights are particularly beautiful. With astronomical telescopes, everyone can broaden their horizons immensely."
With glass, it is naturally possible to grind prisms for spectral dispersion.
Various interference and diffraction experiments can also be conducted.
Ma Lin had completely forgotten about optics.
Thus, he tried his best to encourage everyone to observe more, be more hands-on, and think deeply.
Social productivity was rapidly improving.
If Ma Lin could master the technology of making enameled wire, the takeoff in productivity would be unstoppable.
His subjective feeling was that the current technology of electricity was somewhat simpler than steam engines, machine tools, and the like.
