Matter can be created and destroyed, energy cannot be created or destroyed in a conserved system.

If you present matter with a precise quantity of its antimatter counterpart they'll both annihilate; the total energy of the system will be conserved, but the matter will be destroyed.

A game engine is the base that the entire game is built/ran on.

It's like a computer program game devs use to make and run their game.

Example

A game engine is like a painters canvas.

You need the canvas to create and display your work.

If I'm wrong someone will correct me.

Think of a game engine like 'The construct' from The Maxtrix. It's the tools, physics, and rules a game is built around. Think Ocarina of Time and Majora's Mask. They used the same engine (and some assets like character models) so they kinda feel the same. Another example is Half-Life 2 and Portal. Same engine, similar feel.

Keep in mind, this is not necessarily what is consciously going through people's minds when they think about gender identity. Cis women certainly don't have to think "I am happy with the way society treats me" to identify as a woman. They don't even have to feel "comfortable" with the way they are treated as a woman. It's hard to separate the "experience of being a woman" from "being a woman" when we are the sum of our experiences.

But that is also relevant to what it means to be trans, because it's not just about identifying as something else, it's also about not identifying as something, too. And again having to navigate a world where most other people are using gender as a proxy for sex and sex as a way to determine part of how they treat you means that there are advantages to having an outward expression of gender that fits with the expectations of others.

There are several answers here that are correct, but they used a different method from any of them when the built the Brooklyn Bridge. They built a wooden "room" larger than the bridge supports, and submerged it, and essentially just made two big square holes in the river to work in.

This is correct!!!

Moreover! This is why breathing in the correct manner helps with physiological relaxation. (Look up diaphragmatic breathing). Especially with a slightly longer exhale than an inhale (example: inhale for 4 counts, hold, exhale for 6 -7 counts, hold) helps tamp down the fight or flight system (sympathetic nervous system) by activating the rest and digest system (parasympathetic nervous system).

The reason it works is that it is a backdoor way to communicate to your brain: hey, this isn't a threat. I'm fine. I'm not in danger.

Same principle, generally, as what is being discussed with using the paper bag for hyperventilation.

As social animals, we largely define our sense of self, our identity, in relation to others. This can be inclusive, "I'm similar to these people", or exclusive, "I'm not like those people". For most of us, our individual identity becomes an amalgam of all the different subgroups we identify with.

Now, pretty much the earliest group we get sorted into and identified by is based on our biological sex, which is normally determined/assigned at birth using our external genitalia. Once that happens, we start getting socialized to think of ourselves as belonging to one group or the other and how to present that identity in socially acceptable ways. For most of us, that works fine. For some, they feel like there is a mismatch between their physical characteristics (sex) and the social expression of that sex (gender) and their internal sense of which group they should belong to.

Ultimately, there is no objective, measurable criteria by which to judge a person's identity, because it is in their own mind. We can only look at what they say and do to determine how "legitimate" their identity claims are.

Some peoples mucus isn’t as strong as others, so sometimes it won’t really help healing if too damage a vessel in your nose which is why it continues to bleed and a cauterization is needed.

Usually it varies to person to person but the body will force a scab to happen in the nose if I’m not wrong. I’m no a doctor so don’t take my word on that.

I briefly worked at a place that made things like pre-built ceiling trusses. The tolerance for each board we cut to be assembled into the truss was 1/4inch. So if each board was 1/4in short, you'd be looking at a 1/2in gap at that particular joint.

So yeah, It's not necessarily going to be square when you have tolerances like that.

Listen to the sound of the engine, and look at how the sound relates to the rev gauge. You can do this while parked, with the car in neutral, so long as you’re on flat ground.

The car speed (or wheel speed) and the engine speed are linked by the gear, and detached by the clutch.

In order to avoid grinding the gears, you want the engine speed and car speed to match up for that gear.

Luckily, you don’t need to be perfect!

For example, let’s say you are in first gear, and you’ve gotten the car moving a little. Let’s say you’re driving at 20mph, and that your tachometer says you’re at (I’m guessing here) 6000rpm.

You push the clutch in and take your foot off the gas. The tachometer starts to fall. Try to get into 2nd gear before it falls all the way to idle. If you mess it up, and it drops, that’s fine. You’ll need to give a little gas to get the engine spinning (let’s say 2000rpm) and then come slowly off the clutch.

You’ll either hear the engine whine because it’s not spinning fast enough, or the car will lurch forward because the engine is going too fast.

If you are careful with the clutch, you’ll feel which way it wants to go, and you can adjust with the gas until they’re both happy. Then you can come fully off the clutch. you’re in 2nd gear.

Good luck

When the RPM's get between 2.5 - 3.5 or so on the display; that's the sound and its time to press the clutch and shift up a gear.

  • Down shifting is more nuance so until you're good and familiar with the sounds and associated speeds maybe just ease off gas, use brake, and/or put into neutral to stop or slow down. But essentially the process for down shifting is just the reverse as above.
  • Just never attempt to adjust the gears without first pressing and holding down the clutch and, when shifting, ease off the clutch once in desired gear.
  • Grinding the gears will eventually destroy the clutch, at which point your parent(s) may attempt to put you up for adoption or worse.

the amount of oxygen we have used is minuscule compared to the amount in the atmosphere.

The mass of the atmosphere is about 5.5 quadrillion tons and 20% of that is oxygen.

You need to remember that it is only if we use it with carbon that is not part of the carbon cycle on earth that it is a net increase. So if we burn a tree for fuel and then a new tree grows up and replaces it the same amount of oxygen is released from it photosynthesis.

So it it primary fossil fuels from the ground that use up oxygen and produce CO2. The amount of CO2 is today 412 PPM an increase by 47% from the preindustrial age. let's say 200PPM.

1 PPM =0.0001% so an increase be 0.02%. Compare that to the atmospheric oxygen level of 20.95%. The result is we have used around 1/1000 of the oxygen in the atmosphere since the start of the industrial revolution

This actually makes a lot of sense. So basically when a man (biologically) says "I identify as a woman" he means "I'd like to be treated like society treats woman". And if we treated people equally without any discrimination or stereotypes based on gender, there would be no need for people to identify as another gender than their biological sex?
