Garden By the Bay

Taken from the entrance of the Garden by the Bay.

The daylight was about to end. Regret that I should have taken a lot of photos from this angle.

 

    I question myself why I did not take photos from same point when I came back from it, it became dark, ah I see, we were middle of there when the sound of the lights was playing.

Smaller or Bigger (Unit and its Prefix)

There are units in the measuring. For example metre. 1 metre, 2 metres, 10 metres. But how about 1000 metres? We call it as 1 kilometre. Kilo is equal to 1000. It becomes prefix. When we want small, 1 metre divided by 1000 = 0.001 metre. It is 1 millimetre. Milli is equal to 1/1000. In my school days, I had studied byheart those prefixes : 1 metre 100 centimetres, also 1 metre 1000 millimetre , etc. I could not get them byheart. Then, my father taught me writing the following.

yocto      zepto     atto     femto     pico      nano    micro    milli     centi    deci

deka     hecto    kilo      mega      giga     tera       peta     exa      zetta    yotta


After that he wrote these factors ;
 
10^-24   10^-21   10^-18    10^-15  10^-12  10^-9     10^-6    10^-3   10^-2     10^-1

10^1      10^2      10^3      10^6     10^9      10^12    10^15    10^18   10^21    10^24
