Genesis, academia version

In the beginning, God created the universe. On the first day, God said: ‘Let there be light.’ And there was light. And God saw the light, that it was good.

On the second day, God made the firmament to divide the waters which were under the firmament from the waters which were above the firmament.

On the third day, God created the dry land, and the trees, flowers and grass, and saw that it was good.

On the fourth day, God created the sun, the moon and the stars, and introduced the seasons.

Whilst doing so, the Head of Department (on whose right hand sits God) asked him to review a number of funding proposals, which meant he didn’t have time to make more stars to fill up the vast void of space.

On the fourth evening, God noticed a bug with the light code that meant that the speed of the light from distant stars depended on the season. So he stayed up late fixing that.

On the fifth day, God unexpectedly had to give a lecture because his colleague went to a conference without telling anybody.

On the sixth day, God was creating Man, and was trawling through pages and pages of Matlab documentation when a system administrator decided it was time for a server reboot. The code for telepathy has been lost.

On the seventh day, God finally had some time to catch up with a huge number of emails. Undergraduates will understand why human supplications seldom receive a response.

A frivolous observation on milk

When microwaving a mug of milk, it sometimes goes all over the microwave. (The same happens with canned soup.) I’ve noticed that this tends to happen more often with whole milk than with semi-skimmed milk. My hypothesis is that in whole milk, the higher fat content means that an elastic layer of fat builds up on the surface, which traps any vapour, preventing it from leaving and causing its pressure to increase until the layer bursts suddenly.
