I remember reading about this somewhere and now can't find any information.
Does anyone know about a plan during World War II or even World War I to try to make ships "disappear" by using mirage technology. Basically, the enemy wouldn't be able to see a ship.

I have an project where I'm encountering a speed threshold of some of my 74"F"xx logic and need to go a little faster. Is AHC or another logic family faster? Can someone give me a comparison breakdown of the fastest families in the 74xx series. Unfortunately I need to stay 5v for this application. Thanks!

It is a mammal. It has off-white rings around its long tail. It is reddish brown with a white muzzle and a raccoonish face. It's also about the size of a raccoon, but with a pointier snout. I have a picture of it, so I can cross reference your answers with pictures on the internet. I saw them at Cypress Gardens.

when you consider a square as a quadrilateral it is ONE of MANY regular quadrilaterals.

These regular quadrilaterals include a parallelogram with two different lengths of side and two differently sized angles.

Is a square a regular polygon AND a regular quadrilateral
when a parallelogram is a regular quadrilateral but NOT a regular polygon?

I messed this question up earlier as I didn't realise the question mark is automatically added to the top line!
