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).

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, ...

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 ...

The National Weather Service officially ranked the tornado Sunday, April 15 as an EF2. It maintained that strength, as it crossed 30 miles into Greensboro and then Rockingham County. While we've ...

Tornadoes do occur in the Southern Hemisphere, albeit at a greatly reduced frequency than in the Northern Hemisphere, primarily because it includes the U.S., which hosts about 75 percent of the ...

FARGO — About 98% of all tornadoes spin cyclonically, which in the Northern Hemisphere is counter-clockwise and clockwise in the Southern Hemisphere. This is because tornadoes tend to follow the ...

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 ...

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 ...

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 ...
