A spheroidal body growing from a plant either above or below the ground (usually below), which is strictly a bud, consisting of a cluster of partially developed leaves, and producing, as it grows, a stem above, and roots below, as in the onion, tulip, etc. It differs from a corm in not being solid.
A name given to some parts that resemble in shape certain bulbous roots; as, the bulb of the aorta.
An expansion or protuberance on a stem or tube, as the bulb of a thermometer, which may be of any form, as spherical, cylindrical, curved, etc.
My reality needs imagination like a bulb needs a socket. My imagination needs reality like a blind man needs a cane. Tom Waits
This revolution, the information revoultion, is a revolution of free energy as well, but of another kind: free intellectual energy. It's very crude today, yet our Macintosh computer takes less power than a 100-watt bulb to run it and it can save you hours a day. What will it be able to do ten or 20 years from now, or 50 years from now? Steve Jobs
We forget just how painfully dim the world was before electricity. A candle, a good candle, provides barely a hundredth of the illumination of a single 100 watt light bulb. Bill Bryson
The space shuttle was often used as an example of why you shouldn't even attempt to make something reusable. But one failed experiment does not invalidate the greater goal. If that was the case, we'd never have had the light bulb. Elon Musk
