Sir Isaac Newton essentially created modern day physics back in 1687 when he published his work detailing the three laws of motion and the universal law of gravitation. Thanks to him we all understand what, literally, makes the world go round. We now have a plausible explanation for why the Earth doesn't shoot off into the cosmos like a mishit cue ball, as opposed to the old classics such as the theory of elemental attraction (earth to earth, water to water etc), or because we're at the mercy of God and if you masturbate again young Jim he'll be right displeased and kill us all. This last theory was known to prompt great scepticism in the listeners, along with mumbled apologies, embarrassed exclamations of "Muuuuuum don't talk about that!", and much washing of rather stiff sheets.
However, for years no one has known about Newton's Laws of Parental Motion (Motus Legem Parentis) or indeed any of his Parental Laws (Parentum Iura). This is possibly because it relates only to people with infants. Scientists are known to be rather reclusive and somewhat socially awkward, so procreating can be difficult for them. Physicists have an added reluctance to engage in sex as it falls firmly in the field of biology and that terribly wishy washy field of sociology. Its because there are a lack of scientists with children that we have yet to hear of Newton's Parental Laws. Incidentally its also the reason no teenager wants to be a a scientist, lack of sex being a massive deterrent. So what are Newton's Laws of Parental Motion? I shall explain.
Newton's first Law of Parental Motion states that the mass of an object will increase exponentially when placed in a darkened room containing a sleeping infant, the second law sates that any attempts at silent motion by parents in the room containing the sleeping infant are rendered impossible. His third law states that the amount of noise made by a parent is inversely proportional to how heavily or lightly the infant is sleeping, it is also directly proportional to the new, 'infant influenced' mass of the object making the noise.
In layman's terms, if you drop a pin while your child is sleeping it will make the same amount of noise as if you had dropped a box full of pins (the box being the same size as a small child), and at the moment of impact the infant will be sleeping very lightly guaranteeing they will wake up. Another example is of parents attempting to walk quietly through the room. During daylight hours this can be achieved with relative ease, even when parents have consumed their recommended daily alcohol allowance before 11am. However when faced with this task at night, and having been forced into sobriety, parents will always step on squeaking floor boards which previously didn't exist; and their footsteps which just hours before would have put a ninja to shame with their swishing silence, now sound remarkably like a herd of wildebeest leaping clumsily through the room wearing combination tap / work boots that are two sizes too big. Given the scale of the noise, we can assume the sleeping infant will be deeply asleep at the time but not so deeply asleep that they don't hear the noise, waking in terror for their lives and screaming to let all persons within a 50 metre radius know this.
A more recent, real world example would be a father who attempted to carry a small glass of water from his bedside out of the room. The parent in question was sober at the time, having only consumed double the legal limit of alcohol to get him through the bedtime routine. When relating the incident later, he said the glass of water was not particularly full, nor did it seem heavy or unstable. However, within walking just 2 metres from his bedside the glass of water became highly unstable, resulting in what seemed like a half an ocean's worth of water but was really only half a glassful being slopped all over the floor, bed sheets and the man's pants. A great deal of cursing ensued before he got a towel and cleaned up the water. Interestingly, the infant didn't wake immediately, instead it remained asleep for a time. This phenomenon is known as the 'Relief Lull', whereby the parents falsely believe they have gotten away with making a noise and not waking the baby. They sigh with relief (some giggle) then continue on with whatever they had planned. The infant, sensing the parents are once again relaxed and unsuspecting waits for anywhere between 2-5 minutes before waking and crying; this is just enough time to allow the parents to get started with their chosen activity and thus cause maximum annoyance. This was certainly the case with the man mentioned above, who had just sat down to watch his favourite geek tv show.
As with Newton's laws,there is a possible link between his Laws of Parental Motion and a newly theorised Universal Law of Infant Gravitation (Lex universa est, infans Gravitas). It has been suggested that infants exert a strong gravitational influence on select members of society such as the elderly, broody women, new mothers, and mothers who judge other mothers. The infants gravitational field pulls these people in to give cuddles, kisses, cheek pinches and otherwise forces these rational people to dance like a marionette for the infant's entertainment. This phenomenon has been seen to occur at great distances, and its been observed that the chubbier the infant the greater it's gravitational pull.
So what conclusions can we draw from all this? First there is an exciting new field of science to be studied! Second, parents drink to excess. Third parents should give up all attempts at moving quietly during the night when their sleeping infant is present. Forth, babies are cunning little bastards who will make you their bitch given the opportunity. And fifth, babies may have super powers of attraction. Damn their cute chubbiness and smiles.
