How many times can you recycle a plastic bag? And how safe is the plastic in landfills, etc...? The viewpoint I take for burning is that by burning the plastic, the constituents are readily put back into the bio/chem cycle of the planet. Whereas on the otherhand if plastic just remains in its...
Currently, majority of our waste that does not end up in landfills, ends up in the oceans. There the plastic is bleached and broken down into smaller and smaller granules. This is then swallowed by small fish and the higher you go up the food chain the more plastic fish/oceanic life contain...
My question is that would it be more environmentally friendly to burn plastics bags rather than letting them degrade? They take thousands of years to do so and even then many plastics do not completely break down beyond the molecular level...so instead of letting them hang around in the...
I've been wondering recently about the air quality in cities. Suppose all cars/transport methods were to go electric or clean (electric cars etc...) how much would air quality improve by? In other words what % of the nitrous oxide and carbon dioxide emissions are mobile sources responsible for...
Would it be possible to go to medical school after getting a BASc from a good school in Canada? What sort of avrage/GPA would one have to maintain. How many extra classes/requirements can one look at in order to make this possible...and finally with a good avg/gpa is there a good chance of...
I've noticed that I'm having problems with my memory. For example: I had a course on optics just two months ago, whilst I remember the general ideas, some of the main formulas I can't remember the finer details such as the types of chromatic aberrations what f#'s mean and so forth. This has...
Its more macroscopic lol. Take mechanical and throw in a couple of programming courses and you have mechatronics. I'm pretty sure they will not let you switch in because Waterloo is very very stringent about its engineering program. In addition you seem to have missed two co-op terms and two or...
I just did the opposite. Switched from mechatronics at Waterloo to physics at waterloo. I'm not sure they will allow you to switch into engineering...unless you are starting from year one. Waterloo is quite stringent about their engineering program. Have you talked to anyone about this?
Hi All. I'm an engineering student switching over to physics. I was wondering what would be some of the courses that I would have to take if I wanted to get proficient at crudely modeling physical phenomenon...e.g collapse of a proto solar disk...formation of planets, impacts of comets etc...
Can you please recommend some good books? I've touched upon ODE's and have some PDE's in theory in some of my current physics courses. I will be learning ODE's and PDE's soon enough but I can't wait that long. It's going to hold me back from doing this and having a complete understanding of the...
Hello All. I am a second year engineering student switching over from Mechatronics engineering to physics with a minor in computer sciences. While I have done some programming in C, C++, Java, TCL and Assembler, I would like to know how I would approach modeling physical phenomena...e.g basic...
Thats a little cocky man. There are tons of brilliant people there. My entrance avg was 97% and I got that without trying. But yet got raped first year because of my bad work habits. Just make sure you work hard, that's the key.
