Examples
Berger’s invention detected changes in spikes of voltage produced by our neurons—converting those signals into the seismograph-like squiggles popularized as “brain waves.”
Like a seismograph, the rings pick up the gravity disturbances, and the ring particles start to wiggle around.
The laser generates a line on a graph back at the lab, much like an earthquake-measuring seismograph, and if the ground shifts, that line wiggles a little bit.
He was curious to see the result as recorded on the seismograph, and to know at what hour it registered in Japan.
The following brief account of his seismograph will, therefore, form a not unsuitable complement to his Memoir.
When this is done, however, I trust that due notice will be given, so that the seismograph stations may have fair warning.
But even at noon the disturbance had not subsided, as slight shocks are recorded at frequent intervals on the seismograph.
The seismograph of to-day, however, has reached a stage of perfection where close approximations are obtained in the records made.
