We consider the artichoke (Cynara cardunculus var. scolymus) a vegetable, even though itâs a thistle and more specifically, the part that we eat (and that most people ever see in the store) is actually a flower bud â and sometimes called a head.natomy of an Artichoke.

The watt (pronounced /?w?t/; symbol: W) is a derived unit of power in the International System of Units (SI), named after the Scottish engineer James Watt (1736â1819). The unit measures the rate of energy conversion. It is defined as one joule per second.
Watts are a measurement of electrical power. The symbol for the watt is W and one watt = one joule per second (joule is the unit of energy). So a 60W light bulb converts 60 joules of electrical energy to heat and light energy every second!
