Speed Of Ferrari At The Time Of Collision
From my approximation using Windows Live Movie Maker, the speed of the Ferrari is 140km/h at the time of collision with the taxi at Rochor road.
The distance of 8.78m was measured according to the width of the taxi which is about 1.80 to 1.88 metres. The speed of playback in the Movie Maker was reduced to 0.125 time the original speed. As a result, the speed of video is 8 times slower, therefore this unit has to be included in the equation to calculate the speed of the Ferrari.
If we assume that the time is 1.85s plus minus 0.25s and the distance to be between 8.46m to 8.84m, the maximum speed of the Ferrari is 160km/h whereas its minimum speed is 115km/h, which both exceed the speed limit of 90km/h.

Holiday!
Finally year 1 is done! This mark the beginning of my 3 months holiday. I was a very active blogger until a few years ago when life has became very busy. During that period, I still update my blog once every few month, but rarely wrote about my personal lifestyle. By abandoning my blog for a year, my page ranking fell from rank 3 to 1, which is a big lost of human traffic. Blogging is very time consuming; typically take an hour to write a post, but readers only spend about 5 minutes to read everything written here!!! So I shall keep my post short and detailed from today onwards; not those lengthy posts that you seen many years back. If you happen to be my new visitor, I don't delete posts in the past (eg 6 years ago) so you may find some posts annoyed, immature, childish or arrogant to you. Please take note that today's Ah De is no long last time Ah De as human tend to improve over time.
Instead of writing about my past which is already over (actually nothing much except schooling most of my time), I shall write about the recent happenings and my future.
To people who came from Google Search and want to know more about my course: For pre-uni students who are interested to take Bachelor Degree in Chemistry & Biological Chemistry (CBC) (Bsc (Hons)), don't feel afraid of joining us as this course is not so stressful; it teaches you a lot of knowledge without causing harm to your health. Polytechnic students may need to catch up their JC counterpart during year 1 as what that will be taught are mostly from A level Chemistry. Moreover, there is no Chemistry course in all polytechnics in Singapore, all Polytechnic students came from different backgrounds such as Chemical Engineering, Pharmaceutical Science, Biotechnology, Chemical Process Technology. Basically all these poly courses are either engineering or biology. For your info, Chemical Engineering is half Physics, half Chemistry (NOT PURE CHEMISTRY).
People are doing summer research in my course, whereas I chose to spend a summer holiday doing something that I like. I notice since young, I have different interests as the majority of people living in this world. People watch Soccer, but I don't, instead I prefer to disassemble electronic stuffs at home and I feel good when looking at the transistors, resistors, capacitors, diode, RF choke and chipset. Ever since young, I love to disassemble toys that my mum bought to me. I don't really play toys, but I dissemble it to see how "the penguin climb up the stair" works if you still remember that toy that was played during your childhood time. During primary 3, I ever ask my primary school teacher how transistors work.
What else I am different from others? People love to play games online, whereas for me, my game is to assemble computers, overclock it and then play with computer functions. People love shopping, but I love to explore my DSLR camera. Don't you think I am strange? I think so and my hobby is totally weird. People think the electives I chose was strange. People asked me: "You are a science student, but why are you taking computing module as an elective"?
Over the past few weeks, I did a very interesting research about dandraff and did an experiment on myself. I have seborrheic dermatitis, which is basically dandruffs that will never go away no matter how I wash it or even to the skin centre for treatment. Whenever I sweat or eat chilli, my hair will be needle-like itch and I have that skin condition since 10 years ago.
I went online to read up about this skin condition and there is no study that can confirm the cause of seborrhoeic dermatitis; some source said inheritance, some said cause by yeast, some said cause by stress and there isn't a definite answer. There is nothing I can do about gene error so the only variables to play are yeast and stress.
I believe dandruffs are caused by yeasts, so one day I went to bath. Firstly, wash my hair and face with Ketoconazole (DEZOR in picture below) and let the shampoo be there for 15 minutes before rinsing it away. Secondly, wash my hair and face with Selenium Sulphide (SELDRON, green colour below) and let the shampoo be there for 15 minutes before rinsing it off. Thirdly, wash my hair and face with Triclosan (CLEANZplus shown below) and let the shampoo be there for another 15 minutes. My objective is to fully kill all the yeasts and bacteria on my hair and face, but I know it cannot be 100%, there will always be 0.1% of stubborn yeast remaining.
Therefore after bathing, I applied Miconazole, Hydrocortisone and clioquinol on my face, hoping to further eliminate all the remaining yeasts. Then I sprayed Betamethasone on my hair to improve the scalp. (Betamethasone is a corticosteroid with mainly glucocorticoid activity. It prevents and controls inflammation by controlling the rate of protein synthesis, depressing the migration of polymorphonuclear leukocytes and fibroblasts, and reversing capillary permeability and lysosomal stabilisation.). Sorry I am not a doctor, copy paste from internet. :)
After 1 day, I was shocked to discover that I no longer have dandruff after that treatment. 7 killing or functioning agent used at one go in which 5 of them are anti-fungi or anti-bacteria - Ketoconazole, Miconazole, Hydrocortisone, Clioquinol, Selenium Sulphide, Triclonsan and Betamethasone. This is the same as using 5 antibiotics at one go, hoping to eradicate all the yeasts and bacteria without a single trace that remain. Now it's already a week and my hair and face no longer have dandruff. I am amazed! It may be because my cells produce chemicals that give yeasts a good environment to grow. That may explain why some people won't have dandruff no matter how oily their hair is. In fact everybody hair has million of yeasts and bacteria.
After that treatment, I also vacuum my chairs, floor, wash up my table and clear my bedsheet to prevent any chance of yeasts spreading to my hair again. I even soak my comb and spectacles in the mixture of 3 shampoo below. That proves that yeasts plus cell secretion of yeast promoting agent actually cause dandruff in human.
I know the dandruff will come back after a while when the the yeasts grow back to a few million population again. Considering there are 1000 yeast cells on my hair after treatment and assume that it double after 1 day since it is a eukaryotes, it grow slower. 1 day (2000 yeasts), 2 days (4000 yeasts), 3 days (8000 yeasts), 4 days (16000), 5 days (32000), 6 days (64000), 7 days (1280000), 8 days (256000), 9 days (512000), 10 days (1024000). Assume 1 million yeasts are enough to cause symptoms so it would take about 10 days before the dandruff appear again. This is just a hypothesis, I will try to calculate the duration and post the actual number of days here. I started this treatment 5 days ago and so far no dandruff appear.
