Consider walking along and getting hit by a gust of air. It last for a couple of seconds and might make you adjust your balance, hesitate your next step, etc.

Now think about driving your car down the freeway at 60 when you're hit by the same gust of air. It lasts for a much shorter time, and you have to very briefly compensate your steering, but only a tiny bit.

Now imagine your car is a hundred times bigger and travelling at 500 mph when it the same gust hits. The duration will be so short that it doesn't even register, but the force all across the plane is proportional, so it just feels like a big thump, a speed bump.

Sort of the same principle as speed bumps themselves when you think about it. The whole point is to make you slow down and stretch out the time that speed bump is interacting you. The faster you go and the harsher you feel.

Yes the 3.5 jack has been a standard in personal electronics for years, and you are probably right about they reasons they designed the dual plug thing initially. but I think it was also, at least partially, what was submitted to the FAA and once it was approved it became the approved standard. Unlikely to change until they revisited entertainment systems. If there is no compelling (safety) reason they just don't redesign systems on passenger aircraft.

It's not necessarily that they were less advanced. The Aztecs had irrigation and plumbing as well as city infrastructure that was superior to what was seen in Europe at the time. They didn't have weapons on the same level. And the trick is that doesn't matter how advanced your art is, how great you are at agriculture and growing plants, what sort of medical advances you may have made, if someone else has better weapons and can conquer you.

Now, part of these you also is that Europe was in a sweet spot that allowed for rapid technological growth compared to most of the rest of the world. It wasn't just comparatively easier access to metals, but also that the Mediterranean Sea and many large rivers made rapid communication between different civilizations much easier, and that made it much easier for information to travel and thus improve. If someone invents something in Rome, it was very easy for that knowledge to make it to France, where it could be improved upon.

Likewise, the easier proximity between nations in Europe encouraged wars, which also made them focus a lot more on weapons technology development.

So while there are many ways that the natives of the Americas had developed, their weapons technology was nowhere near enough to stand the chance against the Europeans. That, combined with the impact of diseases that the Europeans brought, since they were more used to keeping domesticated animals, and of us getting more diseases from those, meant that the Native Americans didn't stand a chance.

the song of the inside, a beautiful tune.

You can have Stereo audio just come through one ear. It doesn't mean the amount of headphones it comes out of, it's whether the sound is a mono channel or a Stereo channel.

random access memory was first named that to distinguish it from serial access memory, more familiarly called magnetic tape.

Imagine a library of 1000 books. Ram is like having all the books sorted and ready to easily grab on a big bookcase. All books take about the same short time for you to grab.

Serial access is like all the books are laid out in a long line on a conveyor belt. To get a particular one, you have to stand and wait until the conveyor brings it to you.I

I'll let others explain the modern differences among RAM, ROM, and SSD, and HDD.

They are about as different as you can imagine other than the fact they use a similar fuel. Diesel and jet fuel are often interchangeable, that is true, in fact you can fill a Diamond Piston Diesel with jet fuel, that engine is based on a Mercedes 2 liter automobile engine.

A turbine is any device that is spun due to something pressing against a medium. A fluid turbine turns because a fluid passes over the vanes and moves the, a gas turbine does the same thing but with a gas. There isn't an articulating motion, the more pressure you send through the vanes the faster it spins and the more power you can create. The turbine is a specific part of the engine, the whole thing is called a turbine but if you plow a fan through a tube which has a rod along the long axis and at the end are some veins, that is also a turbine. Those big spinny things they build in fields are also turbines. In a gas turbine like you are talking about, you use compressor stages to compress the air before it hits the actual turbine. Everything spins along a shaft(s).

A diesel engine works by compressing an air/fuel mixture and combusting it such that it pressures the piston back down allowing another piston on the same crankshaft to rise to compress or exhaust. Assuming the combustions create more power than needed to keep the crank spinning you can attach a shaft to the crank and create spinning power.

Articulating devices are far harder on the metals than ones that simply spin, there are some diesels and gasoline engines that are capable of rotating at very high speeds but physics limits you. A turbine, on the other hand, only spins, and since you aren't sending something of mass out and back again (like a piston) your physical limits are a lot higher. Your reciprocating mass on a piston engine is far higher, the faster you go the more apparent mass on your components. A turbine will hit a limit as well, but they are at much higher RPMs.

I've flown fairly new 777s, A380s and smaller airbuses (a320 maybe?) And they all had double jack thingies.

They were full service international flights though so maybe that's why?

Domestic shorthaul budget flights have been single jack though.

Wasn't in US either, so maybe it's region/airline dependent

There are also newer planes that have the dual jacks but both are standard 3.5 mm stereo jacks, but they are backwards compatible with dual jack headphones.

>and most components weren't really designed to be replaced.

Seat are designed to be replaced, and are upgraded (or downgraded) on a regular basis.

My 73yo mun, STILL!

a lot of times fries have MSG added to them, especially at fast food places, so you might be full but you’re not feeling full: that’s the MSG

Older aircraft jet engines could be very smoky, especially at low altitudes. This was a problem for many reasons, e.g. military stealth is tough when the bad guy can see your smoke trail from 30 klicks. The one I'm familiar with is the CJ805 on the Convair 990 circa 1970, and you could see it on landing approach from 5 minutes away.
