Scientific American Covers

I don’t know if you know this, but there are only 3 covers to the magazine Scientific American. One is a picture of a Black Hole or Starry region of space with a grid superimposed on it (to represent our universe) with a provocative caption like “Strange Space: Could our Universe be shaped like a Condom?”

The second has a Neanderthal or old looking skull and the caption says something like, “Shadows of the Past: New evidence suggests our ancestors may have leased apartments.”

And the third is a picture of a cell or Double Helix and the caption is always “KILLER CELLS: New Ways to fight Superbugs!” verbatim.

Very occasionally they have a mushroom cloud and the caption is unrelated “World’s first nano-guitar built.” Those are weird.
