Scuba Diving

David O asked:


If the force on the tympanic membrane (eardrum) increases by about 1.50 Nabove the force from atmospheric pressure, the membrane can be damaged. When you go scuba diving in the ocean, below what depth could damage to your eardrum start to occur? The eardrum is typically 8.20 mm in diameter. Take the density of seawater to be equal 1.03\times 10^3 kg/m^3.

I was planning to buy new snorkeling fins and I’m confused with all the different fin types and designs, any ideas on what types and brands of fins are the best?

Is it a must to know swimming before you do scuba diving? or you can learn both together?
I just wonder, if you do not know how to swim at all, is it possible to do scuba diving? since I think that it is a totally different technique.

I want to be a SCUBA-diving instructor,but I cant just go to a commercial dive school because my family would disown me if i didnt get my bachelors degree,and i guess i want to go to college anyways.Should i major in Marine Biology?,or are there any SCUBA specific majors out there?
