Lessons from physics help reveal evidence for the body ferroelectric
Life is always defying the boundaries of biology, or at least of biology textbooks. You don’t have to look far to find instances where books from other fields become relevant. Flip open a physics book, say, and you might find some especially pertinent examples in the chapter on magnetism.
There you’ll learn that if you break a bar magnet in two, you get two magnets — the new ends created by the break just become new poles. And that if you heat a magnet up enough, then you have no magnet at all: High temperatures randomly jumble all the bits of magnetic material (ultimately orientations of spinning electrons) that had aligned themselves along the north-to-south-pole axis. Luckily (if you think of the laws of physics as luck), you can restore your bar’s magnetism just by putting it next to another strong magnet, whose field will realign the magnetic materials that the heat had jumbled.
