Hey guys, I was actually researching the life of Edmond Halley and discovered that he discovered the relationship between barometric pressure and the height of the sea level. I'm not quite sure what barometric pressure is( I know it has a lot to do with whether fishermen fish or not) and would like to know. Can you also show me some mathematical examples on how to find this and the mathematical relationship between these two things. Also, what is the physics behind this interesting phenomenom. Thank you.
