been a while since I blogged [not that anyone cares ;]
ok, down to the dirty and gritty, it is spring and almost summer. To be honest I don't like the two very much =P I mean there is insects and the heat to beat. And being a major donor of blood to the mossies and the heat is quite tiring [but good for burning the fat ;] I wouldn't have much energy to do much.
HOWEVER, in the shower I thought I might be more positive this summer or heat period. I mean there are plenty of good stuff to experience in the summer right?

I remember in primary school, we'd knock off at 3 and get home at 3.30. It was 38 degrees and everyone was quite beaten by the temperature. Even the air-conditioners called out to be saved, rattling away trying to keep the people cool. Out of the car I got and rushed inside to find a slightly cooler living room, but it wasn't enough. I quickly jumped into the shower and slowly turned the cold water on. Under the shower head, I could feel the heat slowly dissipating from my dark black hair. At first the water trickling to my fingers were warm, then slowly as I turned to tap further, my skin was in a cold heaven. I stuck out my tongue and let the water fall almost gluttonously drinking the water. As the cool water slid down my throat I no longer was in this world of heat. Gone.

Ok let's get to what I wanted to do =P [referring to the title <- just for fun] primary school was about 7 years ago, and global warming had not hit us as much as it is now. so 38 degrees is pretty hot relative to the winter the normal temp then. So at 38 degrees our body is desperately trying to cool our body down, with sweat. This sweat will evaporate utilizing what is known as the "cooling effect". So in order to produce this sweat our bodies must use up energy, and as we move about as well we use up energy so, thus, people would be tired because of the heat. Air conditioners were pretty crap back then, and we haven't changed them since so they are pretty old, hence the rattling noises. HOWEVER, obviously an inanimate object cannot be "crying out to be saved" thus, it must be one of those... those .. what do you call it? english technique.. onomatopoeia!
Well the slightly cooler living room is thanks to the insulation of the house, and the roof. At peak heat [about noon] the gutters play a important roll reducing heat in the summer. As we all know that the earth Rotates at a 23 degrees axis, in summer the sun is approximately 23 degrees at noon. So the gutter is able to block the most direct rays reducing the heat trapped inside by 40%, insulation keeps the morning coolness inside the house and reflects the heat out. However, ventilation like windows and pipes allow heat to flow into the house, resulting in a slightly cooler room.
Turning the tap slowly and allowing the water to trickle does not have any affect. It is pointless =P As we know the colour black is a good absorber of heat, the heat on the hair is greater then the surface temperature of the skin. As the cold water falls onto the hair the heat from the hair is transferred to the water [zeroth law of thermodynamics]. The sensory neurons at our fingers have the ability to sense temperature [as well as pressure etc] at the sensory neurons small electrical signals are sent to from the synapses to the central nervous system and then sent to the brain. This allows up to perceive what we know as cold. Together with the first point we now can conclude that what I was feeling is true, proven by science. Similarly, by drinking cold water the heat is transferred from the point of contact to the water and as the water has kinetic energy we can see that the heat is no longer at the point in contact.
The rest of it is a load of BS =]

fun? or fun?
Thus, the title of this blog =D
