Sig Figs

Calling all of my fellow Science Nerds...
Over the course of my college career I've been fortunate enough to take NUMEROUS science classes. (too many to count) and in each of these we've used the beloved Significant Figures.

Every professor has always taught it the same way. UNTIL now.

Apparently my professor this summer invented his own form of sig figs, because on our homework assignment this week the entire class missed the question. (Meaning, 200 people) and he still refuses to change it.

Just have a look-see and see what you think:

Two significant figures to ME means that you would express the pH as 4.7 not 4.70... 4.70 is 3 significant figures from what I've been taught.

He claims that we could have always asked him about it if we were confused. WELL, I wasn't confused dude. There's nothing confusing about sig figs... until you decide your definition is different from every textbook and considered 2 to the RIGHT of the decimal point. Now I'm worried about what else I might think I know, that he has a different definition for, since our test is Monday.

I know it seems ridiculous to be so mad about it, but I would've had a 100 on this homework assignment (which I desperately need) and I deserve it because I did it RIGHT according to what significant figures are defined as.

I think he just doesn't want to admit that he's wrong.

Rant over.

Wish I Would Have Known...

I recently came across this textbook site..

and I really wish I would have known about it BEFORE the semester started!

It's Campus Book Rentals [dot] com.

[click here.] 

 

Textbooks can get SO expensive, so renting is always such a great alternative.. WHEN you can find your book in a store that offers the "rent" option on textbooks.

One of my concerns about getting books online is that I'll end up getting the wrong book before my class starts and be stuck.. but with Campus Book Rentals you have 30 days to return your book if you need to!

The great thing about this company is that they not only have great prices for their Rented Textbooks.. but they also support Operation Smile. 

Operation smile is an organization that provides lip cleft surgeries for children whose families are unable to afford it. So far they've changed 1,000 children's lives.. and for every textbook you rent, a donation is made to this project. 

So next semester, and even this semester, when you need to purchase a textbook.. Definitely keep this company in mind! It's always a wonderful thing to help someone... so why not use a textbook purchase to do it too!
