Geek Jokes

Hi, everyone. Continuing on in the festive spirit. Here are a few clever Geek Jokes. . .


Some things Man was never meant to know. For everything else, there’s Google.


Black holes are where God divided by zero


An infinite crowd of mathematicians enters a bar. The first one orders a pint, the second one a half pint, the third one a quarter pint… “I understand”, says the bartender – and pours two pints


The truth is out there. Anybody got the URL?


There are three kinds of people: those who can count and those who can’t


Two scientists walk into a bar. The first says, “I’ll have some H2O.”

The second says, “I’ll have some H2O too.”

The second scientist dies.


Entropy isn’t what it used to be.


Have you heard the one about the sick chemist? If you can’t helium, and you can’t curium, you’ll probably have to barium.


A Buddhist monk approaches a hotdog stand and says, “Make me one with everything.”


Heisenberg was speeding down the highway. Cop pulled him over and says, “Son, do you have any idea how fast your were going back there?”

Heisenberg said, “No, but I knew where I was.”


Helium walks into a bar and orders a beer, the bartender says, “Sorry, we can’t serve noble gases here.” He doesn’t react.


Did you hear about the man who got cooled to absolute zero?

He’s 0K now.


What do you get when you cross a joke with a rhetorical question?


Hope you enjoyed these as much as I did. The Heisenberg one cracked me up.

BTW – this is the last day for the Calvanni Book Giveaway. Have to be in it to win it!

Moon Rabbit Breaks Dry Spell

When I read the article today, I could not believe I missed this. I could also not believe the lack of media coverage in general. We’re back on the Moon!

On the 14th December China’s Chang’e 3 lander touched down on the surface of the Moon. This is the first soft landing there since the former Soviet Union’s Luna 24 in 1976 – a 37 year dry spell that followed a previously intense period of space exploration. The recent touchdown follows the Chang’e 1 and Chang’e 2 orbiter missions in 2007 and 2010.

The unmanned Chang’s 3  lander hovered 100m above the surface as it analysed the local features searching for a safe landing spot. Once it was satisfied in its choice of landing pad it throttled down its engine and free-fell to land on its springy legs.

The robotic lander was controlled from the Beijing Aerospace Control Center.

Of course, these days no visit to a celestial neighbour is complete without a robotic rover. A few hours after landing, the Chang’e – named after the Chinese goddess – released its Yutu moon rover. Yutu is named after the pet rabbit the goddess carries with her on her travels. The rover’s wheels were unlocked by the firing of explosive devices, after which the rover unfurled its solar wings and deployed its instrument mast. Twin ramps then inched down to the lunar surface, allowing the rover to roll down them onto the dust.

Yutu is a six-wheeled robot that weighs around 140 kg and has a 10km range. It’s outfitted with navigation and both panoramic cameras and hazard-avoidance cameras fitted to its lower front portion. No reversing cameras though – parking is generally no problem on the Moon.

The solar-powered rover will hibernate through the bitter chill of the Moon’s 14 day night. Once it wakes up it will deploy its nifty Proton X-ray spectrometer, which will be used to examine lunar material, particularly ejecta that will give clues about what lies beneath the lunar surface. The data will also help researchers develop better impact-cratering models.

Yutu is also equipped with ground penetrating radar, which is useful to carrying surveys of the sub-surface up to 100m depth. Variation in the radar wavelength can allow more detailed mapping of the shallower surface areas. Exploration of the deeper areas will be at the trade-off of lower resolution.

I for one am glad the dry spell is over. This is really exciting news.

Was anyone out there following the Chang’e 3 landing?

Need a Laugh? Governmentium has been Discovered!

Here is something I came across a little while ago sure to be enjoyed by all you geeks out there!

The heaviest element yet known to science has been discovered.

The new element is Governmentium (Gv). It has one neutron, 25 assistant neutrons, 88 deputy neutrons and 198 assistant deputy neutrons, giving it an atomic mass of 312.

These 312 particles are held together by forces called morons, which are surrounded by vast quantities of lefton-like particles called peons.
Since Governmentium has no electrons or protons, it is inert. However, it can be detected, because it impedes every reaction with which it comes into contact. A tiny amount of Governmentium can cause a reaction normally taking less than a second to take from four days to four years to complete.

Governmentium has a normal half-life of 2- 6 years. It does not decay but instead undergoes a reorganisation in which a portion of the assistant neutrons and deputy neutrons exchange places.

In fact, Governmentium’s mass will actually increase over time, since each reorganisation will cause more morons to become neutrons, forming isodopes.

This characteristic of moron promotion leads some scientists to believe that Governmentium is formed whenever morons reach a critical concentration. This hypothetical quantity is referred to as critical morass.

When catalysed with money, Governmentium becomes Administratium, an element that radiates just as much energy as Governmentium since it has half as many peons but twice as many morons. All of the money is consumed in the exchange, and no other byproducts are produced.

A classic isn’t it?:)

Creating a New World

I’m still excited about my Jakirian Cycle hitting the real world. All three books – The Calvanni, Scytheman and Sorcerer – and now available through a host of on-line retailers including Amazon (For Sorcerer be sure to put “Chris McMahon Sorcerer” into the search engine) . Ebook versions of all three books are currently in the works and should be available from November.

I’m proud of the way the whole world came together. It has been with me for a long time, and it’s more satisfying than I can say to finally get my Jakirian universe out there. Thanks to all the patient readers of the 2006 edition of The Calvanni, who have waited some time to see what happens in Scytheman and Sorcerer.

The world of Yos was my first major foray into building a unique world.

Around the time I was dreaming up this world, I was reading David Attenborough’s Life on Earth. I think it was that beautiful presentation of evolution that drove a lot of my early work on Yos.

I thought a lot about the creatures and the races, and how they had come to fit into the ecological niches that existed on the world. All of it was driven by the unique astronomy. The world of Yos orbits two suns (OK for the astronomy buffs, technically the centre of mass of the two-sun system). The red sun, which provides only a fraction of the solar input of the yellow sun, regularly eclipses the yellow sun, causing Storm Season. A period initially of intense cold, followed by – you guessed it – violent storms as the world rapid heats up again. This regular period of intense cold gave rise to various evolutionary coping mechanisms.

There were two main routes. Warm-blooded surface mammals who remained active during this time developed the Heat – an accelerated metabolism that provided warmth, but at the expense of the body’s resources. Modern humans on Yos try to resist the pull of the Heat during Storm Season – the time of the red sun Uros. It can keep you alive, but at the loss of control. In the dangerous world of Yos, the overconfidence and loss of inhibition that comes with the Heat can be a deadly weakness.

The second coping mechanism was to get underground. Birds and other animals evolved to be able to dig burrows they could use to ride out the cold. Others went even further, living more and more of their span under the ground. This eventually gave rise to a parallel evolutionary path that existed in the extensive caverns of the Yos. Creatures such as the drakons with their hot acid breath, delved deep into the bedrock, paving the way for others (their prey). Bats were great winners in the evolutionary race. The bounty of the forests of the Yos was drawn down into the caverns, where a whole ecology of luminescent fungi developed, using nutrients from the upper world. Other creatures evolved to eat the fungi – herd animals that never saw the light of the suns. And then came their predators.

Cousins of man – the Eathal – adapted for the caves. They developed acute hearing and a form of echo-location, as well as sensitive eyesight.

Then came new settlers to the upper world, clearing the forests – inadvertently destroying the world below as they robbed the bats of their bounty. And so the ancient enmity between the Eathal and Man was born. . .

Right. Back to world building. Easy to get carried away with this stuff:

One other thing that comes to mind was an idea for the mammal evolution. I wanted a winged race (the Verial), but I wanted them to have hands and wings.

Now in Life on Earth, Attenborough explained how the form of all land animals basically was derived from the same basic quadruped – lizards, monkeys, birds – all had four limbs (and a tail) to begin with. So to have my winged race I needed not only a proto-four-legged, but a proto-six-legged creature. So that’s way on Yos, some land animals have six limbs – or started with them. One example is the narsiit – the winged horse of the plains. It does not truly fly – its metabolism is so fast that when in full flight it needs to extend its wings for cooling, although it does get some aerodynamic lift.  

So all the birds of Yos have two wings and four limbs. In many cases the second pair of legs or arms has become vestigial – I mean who needs the extra weight? But for birds on the ground – or those that need to compete for space in the crowded caverns during Storm Season, the extra limbs really come in handy for fighting . It also means you can shake hands with a bird:)

So what fun have you been having lately with world building?

PS: I’ll be at Genrecon in Brisbane all weekend, so my post replies might be even more weirdly timed than usual


Mars Mystery

Hi, everyone. I have been totally crunched by a deadline this week, which is still looming, so I don’t have a post.

In the mean time, here is a link to a story on about the Missing Methane on Mars. Curiosity has failed to find the expected methane – a likely indicator of life –  that was spotted by orbiting survey craft. The plan was to examine the ratio of isotopes to see if it had an organic origin.

So where is the Missing Methane?
