I was conversing with Amanda just now and I found out that its true that most people don't really apply what they've studied. I mean, who'd actually apply things we studied like algebra or differentiation or calculus in our daily lives right? Maybe only the engineers do.
But isn't life all about Science? Our everyday life will definitely be consists of Biology, Physics and Chemistry mixed altogether that we cannot even make a distinct separation between these. Life itself is Science! Agree?
Manda feels that I'm a thinker. Maybe I am. Like for example, who bother thinking why would the sound of water become softer as they fill up the water bottle? Well, a weirdo like me do! That's because there are lesser (air) space for the air molecules in the water bottle to vibrate as the water fills up the water bottle hence giving a lower amplitude?
Ronnie once asked me why will there be blue-black. Is it because the cells of that bruised part died? The answer is no.
I don't know how true is it but I personally think its because when we bruise ourselves, the blood vessels of the bruised area will rupture and caused them (the blood) to leak into our tissue under the skin (the blue-black is actually the colour of our blood under the skin). And usually the blood will clot together forming a large clot under the skin. The macrophages of our white blood cells will detect the antigen of these foreign particles (blood under the tissue) and will usually clear these 'foreign particles' up. It will heal on its own within a few days/weeks (depends on the individual).
If you notice, the olden days people don't need to study Immunology to learn bout the macrophages and antigens and whatnot. They just rub the bruise with some force in order to heal faster. Its true you know. Reasons? When they rub it, the blood under the skin will not clot together as one huge blood clot. They will be more evenly spread providing a larger surface area:volume ratio so that more macrophages can do the work at one point of time (increased rate of reaction!). Hence heal faster la.
I don't think any textbooks will tell you the process of bruising or how's the process of getting rid of the blue-blacks but its all application. Interesting eh?
Maybe from now on, you'd like to think bout them? It's interesting la. The more I learn or apply, the more I'm in awe of God because He's the creator of all these things!
Think bout it :)

I thought the sound of water become softer as they fill up the water bottle was bcos the water doesnt fall so far down anymore as it fills up so the sound not so loud...HAHAHAAHHA
Eh, why some ppl (aka ME) always bruise so easily ar -.- like kena small tap on the edge of the table also blue black edi. Izit bcos my blood vessel walls too thin cos i got not enuf fat so it ruptures easily ar? @.@"
Heh you're partly correct there for the water-filling thingy. The water doesnt fall so far down because of the space occupied by the water molecules -- means less air spaces for the air molecules to vibrate. The sound (by the vibration of the water molecules) becomes softer since there are lesser air space available as the water fills up the bottle.
And bout your bruises, yeap correct! The hemorrhage occurs beneath the skin which means its underneath your adipose tissues (fats) as well. Since takde banyak padding (in your case), a light tap itself will have a greater impact on the blood vessels hence the bruises. Aiyo Gwennnn eat more fats please!
Aduhai i just had carbonara for dinner 2 days in a row...like late dinner and im still like that. How else to gain weight -.-
Oh man I love carbonara!
How else to gain weight? Sleep early Gwen and don't be too worried with things! They'll make you lose weight! Haha! Eat and sleep more please =)
