According to Garmin -

“The Temperature widget will display the ambient air temperature near the barometric altimeter port. This reading can be affected by body heat. To get the most accurate temperature reading, remove the watch from your wrist, place it on a temperature neutral surface, and wait 10 minutes or more.”

As another user stated, a smartwatch also runs a lot cooler even than an otherwise idle smartphone. It also spends time on your arm as opposed to in your pocket which helps it cool.

This is EXTREMELY difficult to accomplish, however, and usually only done by folks wanting "bragging rights". So called "century shavers" . . . in a practical sense, there is simply no need to be this fanatical about edge wear on disposable blades.

​

I have seen what both a safety blade and a straight razor edge look like under an electron scope, and u/Berek2501 is correct. The "edge" is actually a line of "peaks and valleys" which, after contact with your hair, have the tips rounded off or over. Honing is done to "straighten" or realign those peaks and valleys and restore that keen edge. It's quite fascinating to see how "uneven" a truly "straight edge" is under extreme magnification.

Taking vitamin c when you're sick doesn't do anything to help you, really. Potassium can in some cases, if your reaction to the illness is doing something to cause you to lose potassium (sweating, vomiting, etc) but for just a cough probably won't make a difference.

ELI5: You can pretty easily tell if something is a book right? So you are looking for something to read. Pick it up. Is it a book? No. Toss it. Yes? Read it.

Search engines do the same with everything they process. Malware can't be embedded in a webpage, its a seperate executable downloaded by the page. So anytime the crawler reads something "is it a webpage?" No, toss it. Yes, process it, then find everything it links to, repeat.

> So while he lost those funds, they still exist in the market; it just means that someone else now has access to the profits that were previously associated with his ownership in XYZ Corp.

Not necessarily. Just because the stock value of XYZ corp went down, doesn't mean anything else went up. Stock values are not a zero sum game.

I have had both a regular and cardiac MRI. The regular one was no big deal, just kind of hang out and not focus on the confined space. The cardiac one was exhausting. Pretty much a 2 hour crunch/pilates/yoga/cardio session in a hamster tube.

My sense is that they took some backing images, but all of the important imaging was some variation of hold your breath and tense your muscles for 20 seconds, or exhale and tense your muscles for 20 seconds. Basically, intentionally ensure that you are removing any consciously controlled movement so that they can focus just on the heart and try to snap images throughout the beat.

Like taking screen shots of a moving video. 98% will be crap, but you will get some clear images. Now make 50 attempts over 2 hours, and each attempt requires you to hold a 20 second crunch while remaining perfectly still, in a tube. I literally had to rest in my car for 15 minutes before I drove home. Physically beat up.

Heat rises. When hot air from the blanket open and touch the cold air.. we’ll you know what happens when a cold and a hot front meet. Ever open the door after a steamy shower and see the air move fast? Same principle with the hot air under your blanket just not as drastic

Because this is a thread about how we came to realise the brain and mind were in the same place. It's just a bit of historical context that I thought was worth noting (as it just shows humans have had varied ideas about the mind and brain... Who's to say any of us are correct? Maybe the mind is just a localisation of a collective consciousness idk)

I've looked at some papers, and it seems that usually the material of the container doesn't directly affect the result, but the roughness of the crack "walls" does, as does the crack geometry.

The crack geometry includes lengh too (container wall thickness), and of course water pressure is also a factor.

So your answer is "it depends". It depends on more than just the crack size, but crack length, width, roughness, and water pressure.

here's one of the papers: https://www.nrc.gov/docs/ML0708/ML070860286.pdf

That makes sense. Whenever I get sick, I always have a really bad cough and keep coughing for about a month (worse part of being sick IMHO). I've tried pretty much every cough syrup there is, including codeine. They don't do anything.

I've found lemon juice to be the only thing that helps. Orange juice does nothing (it seems to make it worse actually). I actually keep some miracle berry tablets on hand so I can drink pure lemon juice.

Budgets can be pretty big, and buying a few things extra to fill out the budget isn't a big deal.

Budgets get changed all the time. If you don't use it this year it may be gone the next. Getting authorization to exceed budget can be difficult, while spending what's already authorized is easy.

Take the converse.. if everyone is hyper incentivized to come in below budget you get scrooges that pay poorly, understaff and remove free coffee from the office. You get a bad place to work.

It takes advantage of the fact that light and electrical fields travel about a million times faster than sound (300 million m/s versus 300 m/s). If you think about it, sound is extremely slow. Hearing echoes is a common occurrence and animals like bats even use it for navigation.

No one said something cool can transfer heat to something hot. Cold absorbs heat.

I said as the food warms from the microwaves that heat transfers into the plate. I don't know about ceramics containing metal elements or not.

I do know that Corning Corelle is made from dufferent types of glass, as explained in the link. I have been using Corelle in microwave ovens for almost 40 years and it does not get hot the way a stoneware dish does.

I can only speak from my own experience. If I want to preheat a Corelle plate I have to put water on it as the water transfers heat into it.
