Reply to comment by Dorocche in ELI5: Why is burning wood (local, natural) considered bad for the environment, yet naturally occurring forest fires considered good for climate stabilization? by prendrefeu
> wood burning is illegal in your county.
Illegal?!? I've not heard of that before. In what countries is it illegal to burn wood?

Being a product of evolution, all mammals have developed a safeguard against times of famine. When food is abundant, we store excess energy in the form of fat. When food if scarce, our bodies can use the stored fat to make up the extra energy that is needed.
In this day and age, in first world countries, food is rarely scarce. So any excessive fat that we have is a bit "useless" (note: we all need a bit of body fat to function, especially women, so this is talking about fat beyond a healthy normal amount).
This means that:
-
The excess fat needs to have a blood supply, which puts undue pressure on your heart
-
The fat disrupts the way your body produces and uses insulin, leading to higher risk of diabetes
-
The extra weight also puts more stress on your body in general, leading to more wear and tear: joint problems, feet problems etc
Ann additional thing to think about is where the extra energy is coming from. Foods that are high in saturated fats, salt, or sugar can have additional health detriments on top of the weight gain itself

As opposed to "parallax second"?

The stomach has a pH of ~1 to 3, which is acidic enough to kill some of the microbes/toxins present in bad food.. but some microbes (ahem, Salmonella and E. coli) can survive this acidic environment because of a protective layer called a biofilm.

I’m not an expert but like you said, excess calories are turned into fat (assuming you aren’t lifting weights and turning it into muscle).
Excess weight carries all sorts of issues such as diabetes, heart disease, cancer etc…
It will also be harder on many of your joints such as knees and ankles.
It can also cause self esteem issues if you are bothered by the way you look.
Eating a healthy, balanced diet, coupled with exercise has many, many benefits, both physical and mental.

Let's say you heat your house with a wood fireplace. Every day, you get a wood delivery that is just enough to feed the fire to warm your house. One day you decide to buy more wood than you need. First you make the fire a bit bigger to use more wood, but it's not enough. So you start storing the extra wood in your living room, then kitchen, and then you start adding more rooms to your house to fit all the unused wood.
That's kind of what your body is doing. It's not "useless" fat. The fat acts as an energy store so you can survive longer in times of famine. If you don't diminish your energy intake or use more energy through exercise (make a bigger fire), you will keep storing more and more fat.

Well, the problem is not so much the fat itself as it is the consequences of the fat for your body.
For instance, at some point it may start and collect in your arteries, which is bad news if they ever get clogged to the point that no blood is flowing. This is called an infarction (which can happen anywhere in your body, not just the heart) and can cause tissue damage.
If this happens in, say, your leg, that may cause permanent pain as well as motor issues (as some of the muscle tissue that would be supplied by the blood vessel in question may die off as a result, thus restricting your movement), but if it happens in the heart, this can easily kill you.
Being overweight also causes all sorts of other complications, such as high blood pressure, shortness of breath, and increased risk of cancer, just to name a few. In general, there are all sorts of health risks associated with being overweight.

You burn a certain amount of chemical energy in a day. If you eat more than that, it gets converted into fat for long term storage.
Do this repeatedly for months or years and you’ll end up obese. The consequences are as vast as your waistline - premature heart wear, joint damage, circulatory problems, hormonal issues… nearly every health issue in the book is caused or exacerbated by excessive body fat. It’s catastrophically bad for you, and strongly contributes to heart disease being the leading cause of death in the US.

Reply to Eli5 what happens when you have a gift card to a company that went out it business? by Designer-Recover-940
You might be able to take the gift card to a competitor and they might offer you a discount if you then shop in their store. Mom and Pops are more likely to do this than say Walmart, and stores in the middle sizes are kind of a coin flip.
I will say that every retail store I worked for, big or small, we were told to ALWAYS take competitor coupons, even if they were expired. I have never taken in a competitor gift card, but exceptions are always on the table to gain a new customer.

Reply to ELI5: What is causing the cascade of flight delays and cancellations across the US? by actionguy87
Southwest is having an issue due to their point to point system for flights. Basically there are two ways airlines can set up their flight schedules:
Spoke and Hub - They have a big airport as a hub, and to get to or from a smaller airport you connect through the hub. This is what most airlines uses.
Point to point -This is what Southwest is using. Basically, they have a series of planes and crews doing loops all across the US. So one crew might be based out of St. Louis, and in a day they might be scheduled to fly from St. Louis to Omaha, Omaha to Oklahoma City, then Oklahoma City back to St. Louis.
The issues is best described using an example.
So let’s say I want to go to Fargo, North Dakota from Oklahoma City.
On Delta with the spoke and hub method, I would likely first fly to one of their hubs in Atlanta, then I would get on a flight with people from all over to go to Fargo from there. So if my flight from OKC to Atlanta gets cancelled, I am SOL, but that only affects maybe one other flight (usually a return flight from Atlanta to OKC).
Under Southwest’s model, I might have the same route (OKC to ATL to Fargo), but my OKC to Atlanta flight being cancelled causes issues elsewhere, because that crew and flight isn’t available for their next flight. Jeff, who was supposed to be the pilot for my plane from OKC to Atlanta, he’s stuck in Oklahoma City. So now Southwest doesn’t have a pilot for his flights from Atlanta to Charlotte or from Charlotte to OKC either.
So even though OKC is the only city with bad weather, Southwest has to cancel his flights from Atlanta to Charlotte and Charlotte back to OKC later that day.
Somebody please link that Fox video explaining it below. It’s really good at ELI5 this actually.

Reply to comment by TenLongFingers in ELI5: How is that Pantone colors don't have direct RGB counterparts? by ExternalUserError
Couldn't you also describe color kind of objectively as a certain wavelength? I guess purple has no wavelength associated to it.
Anyway, in the end the human eye of a non-colorblind person (sorry) decides which color a surface is. Two surfaces should be considered the same color if they stimulate the color receptors in the same way.
Pantone colors, CMYK colors and RBG colors still just stimulate color receptors in the eyes, so I still feel like they should be translatable.
There are a finite amount of RGB colors, of course, so we'd have to talk about arbitrary precision real number RGB, not just 24 bit. And another issue I can see, is that RBG can look different depending on the screen. There are calibrated screens, though – I think that means that someone has defined how FF0000 has to look like exactly.
This is not a correction, more a question. How can CMYK, RGB and Pantone be incompatible if the final arbiter is the same human eye?

I wish we would have just embraced the metric system the way that computers have.
For example 1AU is approximately 150 Gm (Giga-metre)

Airline executives are saying it's because of the extreme weather the US is experiencing, but I just heard an interview with a leader of the airline employees union and he said it's way more because of mismanagement and staff shortages.

If you're very lucky, someone took over the old company and still honours those gift cards. The much more likely scenario though is, you now have a gift card that can't be used for anything and is worthless.

It's the smallest possible length at which length can be defined. I brought it up originally because it's a length derived from universal constants; so even if we met aliens who have no understanding of how we measure, or do math, we will be able to translate our distances and their distances using planck-lengths. 1 miles = ______ planck lengths. 1 Blorb = ______ Plancklengths, so you can convert blorbs to miles without ever taking out a tape measure.

Reply to comment by r3dl3g in ELI5 What is Thermodynamics? by SheeshKebabi
Enthalpy is well described above.
With Entropy, think of it as a measure of the “quality” of the energy—specifically, how useless has the energy become? High entropy = more useless. This is important because energy is not created or destroyed, but it does change and in those changes it becomes less useful.
For example, when you burn the gas in your car, you get ~35% efficiency—that is, only 35% turns into kinetic energy of the car. The other 65% isn’t lost…it is just dissipated in the atmosphere as heat and cannot easily be used any more. So its entropy has increased.
