Now, I'm having my microbiology classes. It was extremely interesting! My Prof said, wrote a minute 'dot' on a paper, and divided that into 1000 times. And that is the size of virus, subhannallah how small the creatures are. They are about 20-300 nm. During the journey to learn this block, I feel like discovering and unrevealing a new world. The unseen world.
The more I learn, the more humble I become. Allah the Al-Mighty has the created different world for us to think, to be vigilant that world we live in, is merely - temporary. Nothing stay forever.
