虚文自古向空构,艾字如今可倍乘。

所问逢人惊诧甚,生活何处有真能?

嗟哉小试调音放,讶矣大为掌夜灯。

三极管中知用否,交流电路肯咸恒。

 

凭君漫问荒唐义,负值求根疑窦增。

情类当初听惯耳,事关负数见折肱。

几分繁复融学域,百计联席悦有朋。

但看几何三角地,蓬勃艾草意同承[]

IMAGINARY
 

by Lawrence Mark Lesser
Armstrong Atlantic State University

 

Imaginary numbers, multiples of i
Everybody wonders, "are they used in real life?"
Well, try the amplifier I'm using right now -- A.C.!

 

You say it's absurd,
this root of minus one.
but the same things once were heard
About the number negative one!

 

Imaginary numbers are a bit complex,
But in real mathematics, everything connects:
Geometry, trig and call all see "i to i." Ah-hai!

 

from the Humanistic Mathematics Network Journal # 22, p. 48.
