“We will make electricity so cheap that only the rich will burn candles.”
Almost 20 years before Thomas Edison invented the incandescent light bulb in 1879, this week’s Old Book was published. Natural Philosophy For The Use of Teachers and Schools was published in Dublin, Ireland in 1860. It contains precocious scientific observations concerning the qualities and applications of magnetism and electricity. The excerpts below include chapters, an index, and drawings (sometimes with amusing anthropomorphic figures) of various mechanisms.
