The Relationship between Biology, Chemistry, Physics and Mathematics.

Bismillah.

Hari tu Madam Haliza called, Academic Advisor untuk Medical students. Ada kena isi borang markah quiz, dan result midsem. Tiba-tiba kena kira GPA. Tak terfikir GPA midsem does count. I mean, not to be added up at the end, but to know our

performance, like how high should you bounce back, if it is not the expected one.

Kira punya kira. GPA midsem: 3.52. erk.

Pointer terendah untuk medical students adalah 3.50. erk. erk.

Kenapa tetiba rasa sipi dia macam dah tak boleh selamat? errrrrrk.

Last week was our exam week. Today's last week was my paper for Chemistry. I think, it's today's last week, I started to wonder, why do I have to learn all of these subjects? How do I need them in my life? in other people (who are learning the same subjects as well) 's lives? It shouldn't be a waste, should it? So I got to relate them to my need.

Pikir punya pikir.

Mathematics. All we learn in mathematics are numbers, and equations. Put the numbers here and there. This and this is what you have to use to get this number. And when we got the answer, then? Numbers exist to count. To have

the right counts, we need equations. On what basis are the equations made of?

Contoh la, kita nak buat kotak. Kita kena ada area, in which the length and the width are needed. To what length and width, we need to make a cube, or maybe cuboid? Kalau kotak tu nak guna untuk isi air, kita kena tahu volume pulak. That will need the height. Tinggi mana kita perlu to fill that particular volume of water? Kalau nak buat pintu, kena tahu panjang dan tinggi. Perlu ambil kira the torque, so the door can be opened. Radius yan

g kita perlu supaya pintu tu boleh dibuka dalam ruangan yang diberi. Atau nak kira persamaan seimbang, berapa atom akan hasilkan berapa atom, yang sepatutnya. Kalau nak tahu jumlah, perlu kira dalam unit mol. Nak kira mol, perlu tahu mass and molar/molecular mass. Nak tahu jumlah tenaga ATP yang dihasilkan juga, perlu tahu berapa NADH dan FADH2 yang kita ada. Atau kita nak tahu population, atau kira inheritance based on Mendel's Law.

Sekarang kita ada mathematics. Tapi untuk aplikasi, kita perlu tahu nombor apa yang perlu letak, di mana. Nombor tu kita dapat dari konsep Physics or Chemistry or Biology. Dah letak nombor, kena tahu kira pulak. Nak tahu kira, kita perlu persamaan. Persamaan ini kita dapat dari konsep Physics/Chemistry/Biology juga. Kalau tengok, Mathematics punya topik, tak tahu apa gunanya sehingga lah kalau soalan itu ditanya dalam bentuk application, baru tahu apa guna equations ni semua. Mathematics hanya untuk kemahiran mengira. Jadi kita perlukan ia untuk belajar Physics, Chemistry dan Biology sebab semuanya akan melibatkan pengiraaan walau sedikit. Kalau tak tahu kira macam mana?

Yang paling banyak berhubung kait dengan Mathematics adalah Physics. Konsepnya bermula dari Physics, dan equation dibuat dari konsep yang berlaku. Now, you have the equations, and the numbers to be filled in, applicable to the related concept. So just solve it.

Biology. Asasnya adalah sel. Satu sel dibina daripada beberapa komponen ; cell membrane, nucleus, cytoplasm. These are among the basics. Let's tak

e one; cell membrane. The biological membrane consists of several components as well. It is made up of phospholipid bilayer, which is connected to certain protein serves as pathway of several subtances. The layer is made up of phospholipid; hydrophobic tail and hydrophillic head. Let's get narrower, by taking the protein only. Protein is made up of amino acid, which has amino group in its structure. The amino group is NH3 - Nitrogen and Hydrogen. These two are atoms, exist in the periodic table - the most basic form of things on earth - which are learned in Chemistry. Every single thing in Biology, has its original form, which is made up of bonds between several atoms.

That is for a cell. What then if it's a tissue? That will take billionth of atoms bonded together, I guess. To know the nature of those atoms, how they react, their prop

erties, those are from Chemistry. Then, Biology also considers reaction rate. Especially in the topic of enzymes. The reaction they made in digestion, or diffusion of gases. The concept of reaction rate is learned in Chemistry, what affect will concentration, temperature, make on the reaction. If you have a particular disease, you will need medication. If a pill can supply this much of protein, for example, how many pills do we need to make the rate of reaction goes back to normal? Theoretical and experimental value usually are different. To know the effectivity of a drug, we need to calculate the percentage yield. And that we learn in Chemistry.

Chemistry and Physics. Kita nak buat sesuatu perlu tahu the force or pressure that particular thing has to withstand. Dah tahu kekuatan yang perlu ada, then we have to choose the material. Choosing the material, is based on its characteristic. But what give the material its special characteristic? Chemistry explains that in terms of structure of bonded atoms, type of bonding, the inter and intra molecular forces invloved, and its position in periodic table, which gives the mass, size, and energy, further explains the appearances and characteristics shown by that material.

Konklusinya,

SEMUA TU MEMANG KENA BELAJAR! =.='

Just terfikir..next sem kena ambil Biology 2, Physics 2, Chemistry 2, and Maths 1. Baaaanyak! Kenapa semua....? Ok. Kita dah cari kaitan tadi. Kerana Mathematics menghubungkan semua subjek, Biology ada kaitan dengan Chemistry, Chemistry ada kaitan dengan Physics, dan Physics paling banyak kaitan dengan Mathematics. Ok..dah tahu semuanya berkait..then?

Mereka semua ni berkait untuk apa..?

Kita tahu kaitan ni untuk apa...?

(Selain nak yakinkan hati yang you have to take all the subjects!)

The relationship, must have a purpose. A purpose that they all are related. Manusia punya hubungan pun ada tujuan kan.

One is related to the other. And it will bring us somewhere, but where?

Semua ni ke arah mencari sesuatu. Tapi apa?
