Mark posted a photo of the math question, writing: "My 7-year-old's homework is making me question my sanity. I can't see any mistakes? The number line appears to, indeed, show eighths." ...

New quantum mechanics research is introducing an advanced Pi formula, optimizing complex computations and reshaping scientific precision.

When it comes to doing subtraction problems like this in your head, I suspect that most people who excel at this type of mental math use a method similar to the number line diagram that is shown ...

These two “dependent” cardinals are marked with a frame in the Cichoń diagram. The diagram thus comprises 12 uncountable cardinalities of which no more than 10 can be simultaneously different.

The Feynman diagram for Schwinger’s path is slightly more complicated—this time there’s a squiggly blue line, the virtual photon being emitted and absorbed by the muon. This contributes approximately ...

The average American parent’s science and math knowledge taps out around the sixth-grade level, according to new research. When asked to estimate the grade they’d be placed into for both math ...

How do you calculate that? Choose a line, any line. Since there are six lines, there are six choices. Next, choose a line to be the second side of the triangle.

Copies of the Golden Record, sent journeying into deep space on the sides of the Voyager 1 and Voyager 2 probes in 1977, carries the sounds and music of Earth as well as a series of images to help ...

Of course, this diagram is completely interactive. Finally, Figure 6 shows a parabola and a tangent line. You also can see the equation of the tangent and watch the equation change as you move the ...
