Quantum tunneling isn’t as mysterious as popular discourse likes to make it sound.

Quantum tunneling involves barriers to movement. Think an insulator around a wire. Electrons can freely move throughout the bulk of the metal and even just a little bit outside of the metal, but they can’t transfer to the atoms in the insulating material. However, if you have an arrangement like two pieces of metal separated by a very small bit of insulator, tunneling can become possible. Classical mechanics would say that any amount of insulator between conductors should be able to completely stop charge transfer between conductors no matter how small. However, the wave function that describes an electron’s characteristics isn’t just a single point. It is spread out a bit. If the insulating layer is small enough, sometimes the electron wave functions will span through the insulating layer and a small portion of it extends into the next conductor. This means that if we measure the charge state on both pieces of metal, every once in a while, the charge state of one will decrease at the same time that the charge state of the other increases by the value of 1 electron. Lots of factors change how often this happens, such as a strong electric field. So do we know where the electron has gone? Not specifically, but we know the charge states of the two regions and it is otherwise confined. Do we know if it is the same electron? No, electrons are completely indistinguishable, and this is actually a pretty important concept for quantum mechanics. But whether it is the same electron, or if there’s some exchange that occurs during the tunneling doesn’t really matter. We know that a charge transfer has occurred through a barrier without adding or removing energy.

I see you took the “dull” requirement literally.

I bet having the blades on in the wrong orientation put a ton more wear on your belt, and you were probably burning more fuel than necessary too.

Really? Are you not able to install yours upside down? If you do that then the sharpened edge will be on the trailing side. The mower blades I’ve used would be very obvious that they are upside down, but it is doable.

Of course

If you cut a corner off the bag that should let air in while still keeping dirt/dust off. Then you can cut the rest of the bag off tomorrow.

That said, what are you worried about getting on your mattress over a single night? Do you have pets that will be checking it out?

Am I a joke to you?

The transition is continuous and doesn’t occur at any singular distance from the pole. The angle of the steering wheel would likely go as something like cosine(theta)/r where theta is the angle from the pole (90-latitude), and r is the radius of the circle from the pole which would go as R*sine(theta) where R is the radius of the earth. The reasoning for picking cosine is that the effect you are describing comes from how well aligned the gravity vector is with the acceleration vector to go on a circle. When near the pole, the tires do all the acceleration. When near the equator, gravity does the acceleration. Putting that together the steering angle would be proportional to cotangent(90-latitude)/R. Of course this approximation assumes an absurdly smooth sphere. Any local topology completely overwhelms this effect.

I was going to make a static pressure pun related to luggage, but I just don’t have the head for that.

They need to add heater packs underneath and thermocouple readings. While white is good at rejecting external thermal radiation, it is also poor at emitting thermal radiation. A white surface can be hard to keep cool if the heat comes from within. In particular, white will look like it has a much better comparitive advantage when imaged in IR than is likely to be the case in real usage conditions.

Yellow, red, and gray may be more comfortable in practice.

You’re right. In correcting one typo, I deleted the short press count without noticing.

Have you tried using the key fob for remote start? The app based remote start is subscription locked but on our 2021 if you short press the lock button (edit: twice), then press and hold the lock button until the head/tail lights start flashing it will start up and either heat or cool the cabin depending on temp.

A party that was confident about winning the midterms wouldn’t bother with proposing such an amendment. It’s good to see them sweat a bit.

Not just feels similar; any experiment conducted would yield identical results assuming the source of thrust is perfectly constant without variations.

But rather than continuing to discuss the ways in which you dislike “thrust gravity,” is there a term you would find preferable instead?

Moderately misleading terms is pretty common in real science and technology though. For example, particle spin has nothing to do with actual rotation and instead just has properties that is similar to objects with rotation. So getting obsessively hung up on semantics would be a very frustrating activity even in actual scientific literature.

For accelerating reference frames, you need to move past newtons laws and use general relativity. In that framework, an experimenter enclosed in a box cannot distinguish between acceleration and gravity except in detecting very minute lack of parralelism due to the radial direction of gravity.

I personally would not get hung up on that term.

Binder jet printing is another posibility, both binder jet and sls have that rough surface.

I’m not aware of what that is. I got the phrase from the CGP Grey video, “Circles Waste Space. Hexagons don’t.”

Trump should be irrelevant here, but the article author decided to bring him up for the clicks. That makes this article deceptive and innaccurate. Direct indexing is absolutely not how the Trump family has grifted billions since he took office again. They have accomplished that primarily through crypto pump and dump schemes, but also by abusing the power of the governement to manipulate markets. None of that is related to direct indexing. The average reader definitely won’t be able to replicate the Trump grifting strategies through direct indexing alone.

If you want people to read about direct indexing, share with us an article that doesn’t use such a flawed prrmise to extoll its virtues.

Hexagons are bestagons, but are much harder to fabricate.
