We can’t go back in time, can we?

April3

Hey, with Daylight Saving coming into effect, we lost an hour last night, but where did it go? I was taught that, in order to go back in time, you would need to travel faster than the speed of light (thanks Einstein). But, the physicists tell us, this is impossible, so we can’t have lost […]

Mathematics unlocks the conspiracy myths!

January27

Major conspiracy theories such as a faked Moon landing cannot be true or they would have been exposed within a few years a scientist has concluded. Dr David Grimes, an Oxford University physicist, worked out a mathematical formula to calculate the chances of a plot being leaked by a whistle-blower or accidentally uncovered. He was […]

Flat out in 3 or 4 Dimensions…

August23

How many dimensions are there in our universe? From 2009 (http://phys.org/news/2009-02-fourth-dimension.html): “Creating a unified theory of quantum gravitation is often considered to be the “Holy Grail” of modern science. Daniel Grumiller (left) from the Institute of Theoretical Physics, Vienna University of Technology, Austria, can now at least unravel some of the mysteries of quantum gravitation. […]

Our Universe is Math?

August15

Physicist and Cosmologist Max Tegmark discusses the concept that everything, from sheep to our universe, is mathematical. You can check out Tegmark’s personal page, complete with his 8 universes, mouse cam and poetry, (as well as some helpful notes for students interested in Science) here.

Rogue research with Mathematics

August2

Rogue waves (also known as freak waves, monster waves, killer waves, extreme waves, and abnormal waves) are relatively large and spontaneous surface waves that occur far out in open water, and are a threat even to large ships and ocean liners. (source: Wikipedia). Some of these waves can reach up to 10 storeys high. A […]

Black Holes – Mathematically Impossible?

September29

“Black Holes — the most dense objects in the universe that do not even let light escape — do not exist, a physics professor in the US has claimed. Laura Mersini-Houghton at University of North Carolina at Chapel Hill in the College of Arts and Sciences, has proven, mathematically, that black holes can never come into being […]

The Mathematics of Roller Coaster Loops

March29

Now, I have a confession to make. Yes, it’s true dear H3 readers – a few years ago, while visiting Disneyland, my tech crew were keen to try out one of the roller coasters. I mentioned to them that it might not be a good idea as we had just had breakfast (so you may […]

Sine Method used to measure tallest tree

January23

Scientists recently measured the tallest tree in New Zealand at just over 81 metres. How did they do this? Using lasers and the Sine method – that is, the Sine of the angle formed by the lasers gave the height/hypotenuse. Read more here. (Note: This image is not of the tallest tree but gives some […]

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. […]

And Modern Scientific Dialogue

April22

Euclid’s outdoor presentations are somewhat similar to modern day scientific and mathematical dialogue, where universities and institutes host “open” forums, such as this one at the opening of the Stephen Hawking Centre at The Perimeter Institute – a place in Canada where the frontiers of space are being explored by leading physicists. Free teacher resources […]
