Based on the fun of my earlier Google searches, here are some answers to trivia you could use one day:
1. Why are manhole covers round?
From Wikipedia:
- A round manhole cover cannot fall through its circular opening, whereas a square manhole cover may fall in if it were inserted diagonally in the hole. (A Reuleaux triangle or other curve of constant width would also serve this purpose, but round covers are much easier to manufacture. The existence of a "lip" holding up the lid means that the underlying hole is smaller than the cover, so that other shapes might suffice.)
- Round tubes are the strongest and most material-efficient shape against the compression of the earth around them, and so it is natural that the cover of a round tube assume a circular shape.
- Similarly, it is easier to dig a circular hole and thus the cover is also circular.
- The bearing surfaces of manhole frames and covers are machined to assure flatness and prevent them from becoming dislodged by traffic. Round castings are much easier to machine using a lathe.
- Circular covers do not need to be rotated to align them when covering a circular manhole.
- A round manhole cover can be more easily moved by being rolled.
- A round manhole cover is cheapest to manufacture relative to other shapes because it requires the least amount of metal to cover an opening wide enough for a person to get through.
- Most manhole covers are made by a few large companies. A different shape would have to be custom made.
- If a manhole cover were to be displaced by a car or anything else, it could easily slip back into position and would not have to have any angles matched up.
- If a manhole cover were to be displaced it would not pop or damage the tires of an automobile.
Honestly, who thought reading about manhole covers could be so interesting. That page is a good read.
2. Why This Kolaveri Di?
OK, so here's Wikipedia again:
"Why This Kolaveri Di" (Tamil: வொய் திஸ் கொலவெறி டி, Voy Tis Kolaveṟi Ṭi ?; English: Why This Murderous Rage, Girl?[1]) is a Tamil song from the soundtrack of the Tamil film 3, which was released on 30, March 2012. Written and sung by Dhanush, the song was composed by music director Anirudh.
Oh, word? This sh!t is hot off the presses! We are so hot in India right now! Check it out, I am feeling the beat. Also, this dude is the Indian Fisticuffs with those headphones. Honestly, this thing is blowing up and making Bieber look like a has been.
3. Last one: Why are smart people usually ugly?
This broad must be a super model, because she might be the dumbest person on the planet.
"I am not ignorant" - FALSE - if you are asking these types of questions, you clearly are.
"I absolutely do not differentiate between people who are beautiful and who are not" - FALSE - you are asking the question so you do.
"The reason why I asked this question is because I had recently seen an article on the net about this topic. But I did not get time to read it." - TRUE! This I believe, because I doubt she can read.
