### Galloping Galaxies – Pt III – Mass vs Size

November20

“Size matters!” How often we hear that quote. But does it? Perhaps mass matters too? Jupiter is the largest planet in the solar system. In terms of mass, Jupiter dwarfs the other planets. If you were to gather all the other planets together into a single mass, Jupiter would still be 2.5 times more massive. […]

### Science needs Mathematics!

January31

You might say, “Of course Science needs Mathematics, just as cars need engines.” In some ways, Mathematics is the glue that holds Science together. Mathematics powers the Sciences! This begs the question – “Does Mathematics need the Sciences?” “Mathematics is used in Physical Science for measurements and to show relationships. Arithmetic consists of simple operations […]

### What is the Higgs boson?

July5

The Higgs boson is a theorised sub-atomic particle that is believed to confer mass. It is conceived as existing in a treacly, invisible field that stretches across the Universe. Higgs bosons “stick” to fundamental particles of matter, dragging on them. Some of these particles interact more with the Higgs than others and thus have greater mass. […]

NCEA Level 2 Algebra Problem. Using the information given, the shaded area = 9, that is:
y(y-8) = 9 –> y.y – 8y – 9 =0
–> (y-9)(y+1) = 0, therefore y = 9 (can’t have a distance of – 1 for the other solution for y)
Using the top and bottom of the rectangle,
x = (y-8)(y+2) = (9-8)(9+2) = 11
but, the left side = (x-4) = 11-4 = 7, but rhs = y+? = 9+?, which is greater than the value of the opp. side??
[I think that the left had side was a mistake and should have read (x+4)?]
