Sex is arousing in both the general and specific sense of the term. It's exciting. It's a big, important thing for us humans, and it's something we rarely see because its culturally taboo.

From an evolutionary psychology perspective (and speaking very generally), men get physically aroused when they are in a position to compete for sex, and women get physically aroused when it appears likely they will have sex. Seeing other people having sex triggers those responses.

This is also common across other mammals, so it's likely to go far back from an evolutionary perspective and not something that we can rationalize in terms of human behavior.

I get hungry if there is a long drawn out scene of a person eating a delicious looking meal and them enjoying it immensely.

Same idea.

The job was removed before you used it. The company took away the job. The question is what happened to that worker.

I work at a gas utility. When gas meters became wireless, we no longer needed the fleet of meter readers we had. Nor the auto department to keep that many trucks maintained. My company, seeing that coming, made it known to the meter readers so they could be placed in other jobs within the company. It that doesn’t cover everyone. They may not want to do customer service, for example.

At the self checkout, how many people are replaced? 10? (Across all shifts) do they have an opportunity to be the ones who maintain the self checkout? Some stay in the area to help people using them. It is going to depend on the store.

I remember seeing a tweet from a Texas politician talking about McDonalds becoming fully automated and saying “this is what happens with a $15 minimum wage”

Except they never raised their minimum wage. The change happened anyway. The point I’m making is that the car took away the jobs of horse ranchers, farriers, etc. it was a societal change. That could also apply to your question.

Trader Joe’s (owned by Aldi these days) doesn’t use self checkout. If you move all your shopping there, even if won’t change the rest of the industry, it may make you feel better about your shopping.

Take a bunch of measurements all over the world and do a weighted average.

The impact that killed most of the dinosaurs didn't kill all life on Earth. But the dinosaurs were very large animals high on the food chain, and when food chains collapse, those animals are the first to go. Smaller animals, like the ancestors of the mammals that dominate the planet today, had an easier time surviving.

It also didn't kill all of the dinosaurs. We know the survivors as "birds".

Many colleges are private entities - they can have whatever rules they'd like, and can kick you out for whatever reason they'd like. Many students choose to attend these types of schools because their religious beliefs align with the school's beliefs.

It's all a bit physicsy. But the jist is that each pixel in a camera sensor acts like a little capacitor that can do one of two things:

1. When energized, its capacitance changes based on the amount of light it receives; and

2. It can transfer its capacitance value to an adjacent pixel.

The first function makes sense, but what does the latter have to do with anything?

Well, after the sensor is exposed, the camera's logic starts reading pixel values. Instead of trying to route traces from every single pixel to a memory bus, the camera logic reads the value of the last pixel in the sequence. Once read, this value is discarded, and the value of the next to last pixel is transferred into the last pixel and read. All of the other pixel values in the transfer to their immediate neighbor, shifting them right by one pixel. This read/shift/read/shift sequence continues until all the pixels are read into the camera's memory, creating the final image.

Monstera Fruit just tastes like pineapple, it doesn't have bromelain in it.

If you eat the monstera's fruit unripe, it still contains needle-shaped calcium oxalate crystals like in the rest of the plant, puncturing and irritating the lining of the mouth and throat.

There have been 5 mass extinction events in our planet's history, with the death of the dinosaurs being the most recent. This particular event, caused by an asteroid impact as others have noted, led to the death of about 76% of all species on earth and all nonavian dinosaurs. Fun fact: many scientists claim we are in the middle of the 6th mass extinction event, this one caused by humans. It's called the anthropocene

"Why doesn't everyone feel exactly the same way about things as me?"

Usually it doesn’t; the same number of staff are still present in store but they are switched to other tasks such as restocking the shelves, cleaning or unloading deliveries - or helping customers on the shop floor.

It is possible to get rid of some checkout staff in the switch to self checkout but the usual trend is that rather than cutting service the stores just provide more service in other areas, especially at quieter times.

I thought it was kind of common knowledge that this site is more of a red herring. Yes they do some testing there and have a bunch of lab Bois working there but nothing super secret is actually there because it's where everyone thinks secret stuff is?

The ocean is actually something of an oblong oval that is pulled into that shape by the gravity of the moon. The tides are this oval being rotated around the earth as it (the earth) moves relatively to the moon and vice versa.

No, for our Sun-like stars, iron is their eventual death.

Well the job has already been taken

That cashier job ain't coming back wether you use the self checkout or not

It doesn't work entirety employee free so in many cases you still have employees stacking shelves and such.

But it is ultimately mimimising work force.. which is a thing happening anyway. Because being a cashier has low pay and many kinda cannot even afford to work as a cashier.

These self checkouts are kinda a symptom of companies not paying enough for cashiers so they eventually chose to automate..thereby making stores run with fewer employees.

That makes sense and is why if it is a brown big brick wall it sounds like (Brown (big brick) wall). The mis-ordered adjectives change the way the words must be nested in order to maintain the rule.

The ELI5:

1. Big rock from sky hit Earth.
2. Earth get hot, then super dusty for long, long time. Dusty Earth block light from sun.
3. Plants die. Veggy Dinos no longer have lunch. They die.
4. Meaty Dinos no longer able to lunch on Veggy Dinos. They die.
5. Only tiny flying Dinos survive. Tiny flying Dinos become Birds.

The end.

Follow up question, how do they measure the sea level?

Wow, I don't know how I have not seen that before.

The asteroid hits but that isn't the end of the process. There is evidence to suggest it triggered massive volcanic activity and dramatic climate change. A lot of the extinction doesn't necessarily happen at the moment of impact, but in the many years to follow. It also helps to keep in mind that ecosystems tend to have a domino effect when they collapse: some species going extinct can lead to others going extinction.

Enormous large scale extinction follows the impact, dramatically changing the sorts of species we see in the fossil record. The whole thing is known among scientists as the KT event.

That being said, some dinosaurs did survive, and continued to evolve, and we see their descendants today in birds.

As for us, mammals prior to the KT event were relatively small (think rodent-like). But in the millions of years that follow there was a tremendous evolutionary opportunity with most dinosaurs gone. Mammals gradually evolved into new roles and diversified. Eventually one of those branches gives rise to primates. Out of the primate branch comes apes, and out of the ape branch, humans.

As for why our ancestors didn't go extinct, it's hard to say. But there is no reason to assume they wouldn't. The KT event is a massive extinction event but lots of things survived it.
