What aspect of physics was not known by the writer of this newspaper editorial that ridiculed early experiments by Robert H. Goddard on rocket propulsion above Earth’s atmosphere? “Professor Goddard … does not know the relation of action to reaction, and of the need to have something better than a vacuum against which to react … he seems to lack the knowledge ladled out daily in high schools.”
4/4 Notes taken by Elle Gossman 3 Cell Model generally accepted to show how air circulates around the Earth, proposed by William Ferrel. It divides each hemisphere into 3 cells: 1) Hadley Cell circulates air between the tropical lows and the subtropical highs, at about 2030 degrees latitude. Trade winds are deflected to the left and right in the North and South hemispheres, creating NE trade winds in the north and SE trade winds in the south. The Hadley Cell is strongest in the winter, when there’s the biggest temperature gradient. Goes clockwise. 2) Ferrel Cell circulates air in the midlatitudes, wind shifting from the subtropical highs to the subpolar lows and deflected by the Coriolis Effect to create the West
