In his book Seeking Allah, Finding Jesus, Nabeel Quershi explains how an insight from organic chemistry helped him, as a young Muslim, to accept the truth of the Trinity.

We sat front and center in Mrs. Adamski's lecture hall, not more than three feet from her as she taught. I vividly remember the exact location of my seat because it was there that I first opened up to the Trinity, a moment still etched in my mind.

Projected in the front of the room were three large depictions of nitrate in bold black and white. We were studying resonance, the configuration of electrons in certain molecules. The basic concept of resonance is easy enough to understand, even without a background in chemistry. Essentially, the building block of every physical object is an atom, a positively charged nucleus orbited by tiny, negatively charged electrons. Atoms bond to one another by sharing their electrons, forming a molecule. Different arrangements of the electrons in certain molecules are called "resonance structures." Some molecules, like water, have no resonance while others have three resonance structures or more, like the nitrate on the board.

Mrs. Adamski continued: "These drawings are the best way to represent resonance structures on paper, but it's actually much more complicated. Technically, a molecule with resonance is every one of its structures at every point in time, yet no single one of its structures at any point in time." My eyes rested on the three separate structures of nitrate on the wall, my mind assembling the pieces. One molecule of nitrate is all three resonance structures all the time and never just one of them. The three are separate but all the same, and they are one. They are three in one.

That's when it clicked: if there are things in this world that can be three in one, even incomprehensibly so, then why cannot God? And just like that, the Trinity became potentially true in my mind.
