Recently, I’ve become quite a fan of graphing calculators. Sure, scientific calculators, especially good ones like the Casio fx-991MS (or ES) are good enough for normal high-school mathematics, but when you get to the Calculus and Differentials, you begin to appreciate the value of graphing calculators. In fact, the College-board has made graphing calculators a de-facto requirement for the SAT II Subject Test in Maths Level 2. They are also very useful in trigonometry and geometry, not to mention a hundred times more fun and cool as compared to boring old scientific calculators.
On top of all this, there are some things (in fact, a lot of things) that you can do on a graphing calculator but are pretty much impossible on scientific calculators. A redundantly obvious example is (you guessed it!) drawing graphs. You can also use a graphing calculator to find the maximum and minimum points on a curve which makes differentiation a gazillion times easier.
Now, the problem with graphing calculators is that they’re pretty damn expensive. You can get some of the latest, most advanced scientific calculators such as the Casio fx-115 ES or the Texas Instruments TI-30XS for about 6 Rials ($ 16.5). In comparison, some of the more advanced graphing calculators such as the Casio Prizm or the Texas Instruments TI-NSpire have a prize range of 60-70 Rials ($145 -170). That’s more expensive than my cell-phone. I’m planning to buy something comparatively cheap yet dependable such as the Texas Instruments TI-83 or the Casio fx-9750.
The Tallest Building in The World to be Built in Karachi … Wait, What?
I still find myself in a state of incredulity, even after the news has been repeatedly broadcasted on several news channels, printed in several newspapers and mentioned in a lot of online articles (see here, here and here). It’s too good to be true. I mean, it’s one thing for a country like the United Arab Emirates, ninth richest in the world, with a thriving economy, a small population, tremendous resources and excellent international relations, to initiate such a large scale project, but Pakistan… seriously?
I’m also a bit worried about the security problems the building may cause. A huge skyscraper like this isn’t a good idea in a country infested with several terrorist and militant groups. It’s like literally inviting the Taliban to do a second 9/11. Anyway, the project was initiated by the (in)famous Pakistani business tycoon, Malik Riaz. The building is to be called Bahria Tower (the name is still uncertain, though) and it is planned to be built in or near Karachi, Let’s hope all goes well and this building helps recover Pakistan’s doomed economy (and it doesn’t get hit by hijacked planes).
