Did You Know … DNA factoid

February25

DNA, the long molecules containing our entire genetic blueprint, are about two metres long when unwound, but pack into cell nuclei that measures only 100th of a millimetre across.

Here’s looking at you up there!

July6

In a wonderful display of photographic expertise, this remarkable photo taken by Dylan O’Donnell in Australia, shows the International Space Station crossing in front of the moon. Click on the picture for more info. It took Dylan over a year to get this picture and he attached his camera to a telescope to effectively create […]

Now that looks really weird!

May20

Lakes in the desert, the moon larger when it is on the horizon, Escher’s famous sketches – and, then this recent pic which somehow doesn’t quite seem right? The scale is not correct…or, is it? (For an explanation, check out the Post Support.) Optical illusions are a fun way to get connected with Spacial Geometry. […]

Great Galloping Galaxies in 4GB!

January24

The Hubble Space Telescope of ESA has captured the largest and sharpest image of the Andromeda galaxy that lies at a distance of 2.5 million light years. The image was first released at the meeting of 225th meeting of American Astronomical Society (AAS) in early January and is comprised of 1.5 billion pixels. It uses […]

Scale that Rock!

November13

After a 10-year journey, the space probe Philae has landed on the 67P/Churyumov-Gerasimenko comet after being launched from the space probe Rosetta. Astrophysicists hope Philae will unlock knowledge about the origins of the solar system and even life on Earth, which some believe may have started with comets seeding the planet with life-giving carbon molecules […]

The depths that Math goes to…

July7

First, a few basic mathematical facts about our oceans: …which made me think about the equation for water pressure at different depths. Pressure¬† increases by 1 atm with each 10 m of depth (at sea level the pressure is 1 atm). An “atm” is Atmospheric pressure, which is the force per unit area exerted against […]

The Mathematics of Scale

April30

Hey – do you enjoy making model cars, boats, planes, dolls houses, or even F1 racing cars? Modelling is great fun and most model kits come with a scale on the front of the box, such as 1:50 or 1:100. I recently saw a modelling kit of the Starship Enterprise, which had a scale or […]

Scale – the Mathematics of Supersizing without Fries

March11

In this picture it seems that the golf ball is enlarged too much for our budding maths student!! There are two ways to look at scale – one is that similar objects (that is, objects which have corresponding angles the same) also have their corresponding sides in the same ratio. For example, say we have […]

Misleading Graphics

January19

This graph (from The Australian) caught my eye today as summer temperatures soared in parts of Australia. Just a pity that there was not a Mathematician on hand to show the scale more accurately? You might be able to guess what the starting value is but, in essence, this is not good graphing from a […]
