A lot has been written about Freemasonry in recent times. One of the most prominent features of the iconography associated with free masons is the Eye of Providence. The traditional depiction of this involves a triangle or pyramid shape.
If you have read the paper Central Dogma of Molecular Biology by Francis Crick, you might have noticed that the paper is filled with figures that look like above screen grab. It is a triangle and has some circles. This would actually be a very smart way to sneak in Masonic iconography. Was Francis Crick a free mason? It is actually possible, as it has been argued that some of the most powerful and intellectually gifted people have been part of free masonry.
