why do dolphins...?
I heard on a program that dolphins have a thin layer of water surrounding their bodies that reduces and almost completely gets rid of any drag, and I was wondering what caused them to always have that layer? What makes it stay with them?


I originally posted this under zoology, but now I realize it probably has more to do with physics.

if the world is millions of years old then the sun would be right on top of earth because the sun is burning at a rate of 5 feet per second right now and add it up. also, the earth's magnitisim would be so strong that the tides would have flooded the lands twice a day. also, the rock layers were not made over millions of years, it was formed in the flood of noah. carbon 14 dating is also inaccurate because it can only date 30000 years. if you are a christian, catholic or believes in god, bible, or torah, then u r calling god a liar, which i wouldn't do.

I'm working on polar coordinates and I would like to know how to approach this problem. Please do not solve for me since I do not wish to know the answer anyway. Here is the problem for reference:

To the nearest integer, what is the distance between the points of intersection of the polar curves:

r = 4cos(theta) and r = 2 / [cos(theta) + sin(theta)]

Should I convert to x and y form first? And then I don't understand what the distance between the points of interesection means here...should there even be a distance between the "Points of intersection"?

Also, this is to be done without a graphing calculator or utility.

The buildings' structural integrety was dependent on the outer perimeter which in turn was dependent on floors bolted to the inner core preventing the outer perimeter walls from buckling out.

What also shocked me is that there were only 3 stair ways (wells) that were standard in size! NOT built for evacuations.

Assuming that you do not take a bathroom break right after you eat or drink something, does your body gain exactly the same weight as what you just consumed? For example,

- A person weighed 100 lbs before eating
- Person eats a 1 lb steak
- Person gets on the scale and weighs him/herself (assuming no bathroom break in between)
- Will person weigh exactly 101 lbs (original 100, plus 1 lb of food) or will the body decompose that food and weigh less than 101 lbs?

No... I don't worry about my weight. I'm just trying to satisfy my curiosity and understand how our bodies process food and if foods weigh less once it's in your body after the body starts to process and decompose the food. Not sure if this fits into health or molecular biology or medicine, but I'd appreciate everyone's thoughts!

Two weeks ago, I was over at Lake Tahoe (elevation 6,500 plus feet) and over there, the sky is the bluest of blue. Had never seen a more beautiful sky. Same thing happened in Salt Lake City (elevation a tad under 5,000 feet) a couple of days before.

UofCalifornia Berkeley is doing what appears to be a really cool science project where you search for microscopic pieces of dust from comets that has been trapped by space vehicles. I was wondering if anyone was doing it and if it was as cool as it looks?
