A lot of people think that to get to orbit, you just have to go up, but actually you need to go sideways.

Imagine throwing a ball that leaves a visual trail behind it. You throw it straight up, it comes straight back down and just leaves a vertical line. Throw it across the room, and it makes an arc. Take it outside, throw it really hard, and it makes a bigger arc. Zoom the camera out, and throw it so hard it goes over the horizon. It leaves a pretty long arc right? If you throw it hard enough, that arc goes farther and farther past the horizon until it misses the ground entirely and comes right back around to you. That's an orbit!

But that's only part of it. You see, any time you impart force on an object in orbit, you only change its trajectory, not its current position. Since your arm is now the lowest part in the ball's orbit, you can never raise that point above where your arm is. But you can affect the other side of its orbit–the faster you throw the ball, the higher the opposite side of the orbit gets. Let's head up to the highest point in the ball's orbit, and give it another push. Again, that doesn't affect its current position, but it does affect its trajectory. Making the ball go faster forward increases height at the opposite side of its orbit, so if we push it with the right amount of force, we can make its orbit circular!

Now you know enough to get a rocket to space! Well, kind of. You also need to know about fuel and the tyranny of the rocket equation, but that can wait until you play Kerbal Space Program or get a job at NASA

I knew something once. It was awful.

I've watched a lot of Star Trek so I know a lot about gay space socialism

Did you know that having a constantly open mouth as a child is really detrimental to the development and growth of your mouth's palate, your overall posture, your nose, and many other parts of your facial and bodily structure?

Physiologically speaking, your mouth should be closed most of the time. If it is, the crown/tip of your tongue should rest right on top if your alveoles, ie. just before your upper front teeth. This leads to your palate being formed and molded as a child into what you should know today. If for some reason you only rarely have your mouth closed as a child, this can lead to a deformed palate, making it more difficult to speak in the future, breathe etc. Furthermore, you are more likely to get sick since you're not breathing through your nose where all of the bacteria you passively inhale through the air are filtered out by your tonsils. Additionally, your nose may be malformed by its irregular use as well since the air your breathe in and out helps form your nose too.

Potential reasons for not breathing through your nose might be problems with your jaws (overbite/underbite) or teeth, inflamed tonsils that hinder your ability to breathe through your nose, a too short tongue frenulum that hinders the ability to properly reach your palate, and more.

Happy breathing. :D

Inertia is a property of matter

If you build a linked list in C, and put the pointer to the next entry as the first element in your struct, then you only need a single variable (and two comparisons) to do sorted insertion into the list.

i can whistle continuously without the need for breathing stops

Mitochondria is the power house of the cell

I used to know, but now I'm not so sure anymore.

I know a fun fact:
You know how a packet of 8 bits is called a byte? A packet of 4 bits, which is half a byte, is called a nibble!

Not yet, but I'll keep you updated.

I have approximate knowledge of many things

Be careful. Before you know it they’re making you drink hemlock for corrupting the youth and idolizing false gods.

I think I've... no, I've never done any of that before, sorry.

the sun is the biggest star in our observable solar system

If you're ever looking for cheap jewelry/earrings, you should be very very careful.

CTV Marketplace did an investigation a few years ago, and they found that a lot of children's jewelry contained high levels of lead and/or cadmium. These pieces were found in multiple places, including Claires and H&M. Some children's makeup was also contaminated.

Just fine dining and breathing, I'm afraid

According to Descartes I think therefore I am (and that's all I know), but to be honest I'm not convinced...

This could be the requirements for a job

• 5 years of experience with something (E)
• 2 years of experience with anything (D)

I have experience with stating correct opinons

I have experience living as a human

'Something' is what we abstractly call that which is both not nothing and has some significance to us beyond being merely anything.

I know a guy, I'll hook you up

Ok who's idea is this? I want a name.

I know nothing about anything.

I heard Farmer's knows a thing or two, because they've seen a thing or two.

I like beans

I got experience with yo Mama's ass

I can blow balloons up with my nose. In fact, I can even multitask and do one with each nostril. I also learned to do them with my nose before my mouth (don't ask why, I really don't know. Yeah I can be a bit weird).
