A lady correspondent writes to us, giving her idea of tbe philosophy of the facts recorded in our recent article on this snbject. We will give a condensation of her letter, which is to the effect "that heat is never strictly speaking evolved by the agitation of water; bnt, the cause of elevation of temperature, when water flows along shutes, tubes, or is shaken in a patent churn, is due to the friction of the globules of water against the solid material with which they are in contact." She finds fault with us for saying anything against poetical expressions, and, as a lady only can, defends the poets from the charge of writing false science, in such a manncr that we must refrain from argument, hoping, however, to hear from her again.
It’s Time to Stand Up for Science
If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.
I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.
If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.
In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.
There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.
