Ezekiel’s description is pretty wild: Ezekiel 10:12-21 Their entire bodies, including their backs, their hands and their wings, were completely full of eyes, as were their four wheels. I heard the wheels being called “the whirling wheels.” Each of the cherubim had four faces: One face was that of a cherub, the second the face of a man, the third the face of a lion, and the fourth the face of an eagle. Then the cherubim rose upward. These were the living creatures I had seen by the Kebar River. When the cherubim moved, the wheels beside them moved; and when the cherubim spread their wings to rise from the ground, the wheels did not leave their side. When the cherubim stood still, they also stood still; and when the cherubim rose, they rose with them, because the spirit of the living creatures was in them. Then the glory of the LORD departed from over the threshold of the temple and stopped above the cherubim.While I watched, the cherubim spread their wings and rose from the ground, and as they went, the wheels went with them. They stopped at the entrance to the east gate of the LORD’s house, and the glory of the God of Israel was above them. These were the living creatures I had seen beneath the God of Israel by the Kebar River, and I realized that they were cherubim. Each had four faces and four wings, and under their wings was what looked like the hands of a man.
For a while people were doing AI prompts for biblically accurate angels (sometimes mashed with other characters). I can only do so much with sugar cookie dough.
My lab has weights that get calibrated against a NIST standard annually. We use those weights to perform daily quality control that our scale is accurate (to +/- 0.01g). If the quality control fails then we recalibrate the scale.
