I mean, brands of electronics launch so many models of smartphones, tablets, computers and TVs with different RAM and storage capacities, inputs like HDMI and USB, screen sizes and so on that we can't decide which one to buy.

But as I observed, domestic appliances like washing machines, dishwashers, ovens, fridges, irons, vacuum cleaners and so on nearly stay the same and not many of them are launched so often. Their main functions approximately have stayed the same, except detergent adjusting and less water consumption for washing machines, for example. And ovens adjusting time of cooking according to type of dish. And robot vacuum cleaners. And appliances with Wifi connection

Like the capacity of washing machine doesn't bother us, for example, but we're disappointed when buying a smartphone with 4GB RAM and 64GB storage but seeing another one with 8GB RAM and 256GB storage.

Plus, we don't change domestic appliances as often as smart devices, like I had a washing machine bought in 1997 working until 2022 but changed 9 mobile phones since 2006 to this day.

Why is there such a difference?

Granted, there would be exceptions, but in general: Did you go to sleep late in your teens or early twenties? No worries, if you're free the next day, you may as well sleep untill noon. Past your 30s or 40s, you end up waking up around the same hour you normally do regardless. Then there is the elderly, who only sleep a fraction of the hours they used to do years ago.

Besides "you're older", what changes happen in our brains or bodies that make you feel the bed is throwing you up sooner?

I love shrimp, for example, and it's low calorie. But, I cook shrimp with butter. Curious to know how many calories I'm adding when I do this.

Salt isn't regularly considered a spice, nor is it discussed as a vitamin like A, B, etc. But isn't it necessary in small amounts for humans?

Read this phrase from Hubblesite and was confused, "In 1929, Edwin Hubble provided the first observational evidence for the universe having a finite age. Using the largest telescope of the time, he discovered that the more distant a galaxy is from us, the faster it appears to be receding into space. This means that the universe is expanding uniformly in all directions."

If the speed of expansion is uniform, shouldn't distance not even be a variable?

Hi all, I didn't know how to formulate the question in a non stupid way so I'll explain.

If the light we see from stars in the sky are actually "the past" as they've left their source light years ago, from another point in the universe another planet sees our Sun's light the same way, correct?

If that's the case, if there was an "universal year" or an "Universe's current year", would all the stars and planets be living in the same year?

Maybe I am 5, I feel 5 right now.

Thanks :)

Apart from a blue whale there have not been any significantly large animals since the dinosaurs roamed the planet. Why haven’t we seen another large species since that time?

In the past, if someone was showering and the toilet was flushed. The water in the shower would go suddenly hot or suddenly cold.

Why did that happen? What changed to prevent it?

I get the impression that it is a big deal, but no amount of YouTubes have made me understand exactly why?

Hi guys, I was recently browsing some quotes out of boredom, and saw one said by Jobs:

"The manual for WordStar, the most popular word-processing program, is 400 pages thick. To write a novel, you have to read a novel - one that reads like a mystery to most people. They're not going to learn slash q-z any more than they're going to learn Morse code. That is what Macintosh is all about."

I can understand the meaning behind it but got curious about the phrase "slash q-z" as it seems not to be a common word and cannot find much about it on Google.

I hope that makes sense. As it heats up, it gets louder and louder until it's a roar. But when it actually boils, it goes really quiet again.

I live very near the pumping station (an old quarry) where my drinking water gets extracted.

Why does everything in the house gets full of limescale while the water is ok to drink?

Since i was young ive never understood how rainfall is measured in inches. I'll hear in the news that were expected to see 2-3 inches of rain per hour (currently in the middle of a brutal storm). How is this determined? Wouldnt inches all be determined by the size of the "container" or the locations terrain, rather than the amount of rainfall. Thank you

Original Title: ELI5 Why does the English language have so many words where one or more letters are silent. For example why couldn’t “Knife” be simply written as nife or whatever combination of letters that make pronunciation obvious.

It's been estimated that in all of Earth's history, there have been 7 supercontinents, with the most recent one being Pangaea.

The next supercontinent (Pangaea Ultima) is expected to form in around 250 million years.

Why is this the case? What phenomenon causes these giant landmasses to coalesce, break apart, then coalesce again?

I remember when I was a kid I got one of those toy muffin ovens that would actually make muffins. But it wasn’t plugged into anything, so how do they work? The muffins tasted nice and everything.
