In a “normal” electrocardiogram (ECG), the transition of the QRS axis in the precordial leads occurs between leads V 3 and V 4 (i.e., there is a dominant S in V 3 and a dominant R in V 4).

About half of all spiral galaxies appear to be rotating clockwise and the other half counterclockwise. The direction a galaxy rotates depends on your perspective. As an analogy, consider a spinning ...

The Sun's counterclockwise rotation (as viewed from its north pole) originates from the initial spin of the solar nebula, a remnant of the larger cloud from which it formed. The direction of this spin ...

Spiral galaxies imaged by JWST that rotate in the same direction relative to the Milky Way (red) and in the opposite direction relative to the Milky Way (blue). The number of galaxies rotating in the ...

Hurricanes spin counterclockwise (like all low pressure centers in the northern hemisphere) because of the Coriolis Effect. Because the equator rotates faster than other areas of the Earth's surface, ...

Sixty percent of the oldest known galaxies seem to be rotating clockwise an asymmetry so extreme that one scientist described “any person looking at the image can see it.” The result, based on 263 ...
