I know that diesel is generally cheaper than gas, and that diesel engines seem to last longer and are slightly more efficient, but is there any one or two overriding reasons from an engineering standpoint that large vehicles are usually designed to burn diesel instead of gas (I know that diesel stinks & tends to pollute more, so presumably that is why we don't see more diesel cars)?

I don't get it, like cos 2 times (-3) is still a minus and 3 times it is still a minus and so is 4 times; so how come the first sum is a plus?

I was told the other day by someone that when we are born we officially have 24 senses but because we don't exercise them we loose the ability to use them n thus we only end up having 5 senses that we use, smell, sound, sight, taste and touch.
Has anyone ever been told this? And do you think it is true.

If objects are falling from the sky, whether they are rain drops or aircrafts, what is the fastest recorded speed ? Can they max out there speed and simply not get any faster or do they continue to increase in speed ? If they continue to increase, what is the fastest possible speed, assuming the least resistance ?

I am a visual and analytical person and supposedly math isn't used that much like in General Chemistry nor Inorganic Chemistry. Some people tell me is the easiest class of all the Chemistry classes and other tells me is the worst.

I am not a numerical person and I have had trouble with the past classes Chem classes but I passed them.

Being a visual person do you think is going to be better for me?
