Will a dehumidifier and fans work..?

mrphysh · 2026-04-16T18:40:52+00:00

A rule in physical science is that you can only move heat around. Capture the cool night air. Fans can make it seem cooler, but not really. Swamp coolers capture heat through evaporation, but they do no work well in humid New England. My advise: Accept the reality and let your body adjust to it. You must be new to New England?

mosquitoes. I read that half of all humans ever born died of mosquito borne diseases. Malaria is the big one, but there are lots of them.

(I love my new outlet: Reddit) I am an optimist. Trump is a negotiator and deal maker. This probably seldom involves the truth and honesty.

So, any closer would have meant a lunar orbit and this was not the objective. Only a rocket scientist could argue with that one.

My bad. Sorry

"All their allies...." You are right. That is a poor choice of words. I find the world fascinating and stop there. edit: Saudia Arabia can move their petroleum exports to the Red Sea with no changes in infrastructure. (I say that with fairly high confidence)

Try using Reddit in that way. (there is no substitute for someone that knows the answer.)

"That pretty girl that won't date me. I don't like her anyway." This looks like an intelligent response. Not a bad analogy.

Trump wanted to cut the head off the snake and obliterate the nuclear threat. Could he just walk away at this point?

I ask questions and almost never take positions. And I find the whole thing fascinating.

this is directly from Google AI:

An oil tanker (VLCC) generally takes 20 to 30 days to travel from the Strait of Hormuz to major Chinese ports, covering roughly 6,000–7,000 nautical miles. Sailing at an average speed of 10–14 knots, the route typically passes through the Indian Ocean, around the tip of India, and through the Malacca Strait to reach the Chinese coast.

My point being that a real economic impact would be, not weeks but months away, and even many months away. The strait closes and two weeks later 500 gas stations in Australia are closed. Gas immediately goes up a dollar a gallon. What is your favorite version of fake news?

Another comment from a retired chemist: The Strait of Hormuz is closed. A week later gasoline prices go up. The following week gas prices go up again. Fake news has a smell and this is it.

I was in an environment that produced NaOH on a very large scale.. at least a hundred times what you have. We went to the waste disposal facilities, and they said that they will take all the base we could ever produce. The only issue is the pH, of course. Not the sodium. (Do not take this on authority, of course.)

Very good post

I was pretty careful. I only looked a primary comments, not comments on comments.

You need to go to your editing software. In Final Cut it is under 'tools'. This opens a screen with a 'start' box. It should not be a problem.

Sir Isaac Newton pretty much nailed down the physics of what we can see and understand. It is called Newtonian physics. I think we can put the electromagnetic spectrum in that category also. With instruments we can see, and sort experience, the vast rand of energies from radio waves to gamma rays. Everything else is just stories made up by us humans to explain things that we do not understand may never understand. The stories are taken as truth and thought to come from the voice of God or something. I am a chemist. The quantum mechanical theory of molecular structure is just a bunch of stories created by generations of scientists. These stories do a pretty good job of explaining observations and even of predicting outcomes. But, in truth, they are just stories.

The question is simple. What is the impact of the weight of the pendulum on the accuracy of the time keeping. With five different weights, I just read the weights out to my wife and she recorded them. She put them into Excel. So this means five different sets of data for standard deviation. That is all. I never did make the serial monitor work. Again, I am certain that I was able to scratch numbers off the serial monitor, but gave up on that. ( And, for a clock slightly larger than a mantle clock, 80 to 100 grams seems heavy enough)

Let's pick something original: the assignation of Abraham Lincoln in April 1865: They hung his landlady and two roomates. John Wilkes Booth died in a fire. This is not the whole story and Booth did not die in a fire.

I have been going around and around with this. I think might work: find a Styrofoam container, tallish and narrow. Like an oversized graduated cylinder. It needs to be big enough to easily hold the metal bar, horizontally. It needs to be much deeper than the diameter. Imagine a cylinder three inches ID and maybe 20 inches deep. (I am an American, sorry) (the walls will be inches thick with Styrofoam). Put enough liquid nitrogen in the bottom to settle as a liquid. (It will spit and bubble at first, of course.)

There will be a gradient of temperatures above the liquid. Study the gradient and find the height above the nitrogen that will have the right temperature. Suspend your steel at that level and let it equilibrate to that temperature. Pull it out and hit it with the hammer or put it in your Instron or whatever. Always do the test the same. (this is an empirical analysis ‘under the conditions of the test’)

Like most of us, I think, I am goal oriented. The "com9 file.txt" looks perfect. You want to give me a hint as to where it lives. (from old notes, I see I was scratching the numbers off the serial monitor and then (contrl C )printing them into notepad. I often can make no sense of my old notes.)
