Oh, so 229 miles per second?

I geuss that is strangely fast, is that from when the nose of earth passes some invisible but certain marker, and its body travels 229 models and it's tail passes the 229th mile as the timer expresses 1 second to have passed.

But again the idea i mentioned, what is a state that is 200 miles across?

Imagine a state 200 miles across, on the bottom of earth, and now imagine the earth moving along a line; now imagine in the near distance located on that line is a ruler with a replica of that 200 mile long state,

So there is the 200 mile long state on the bottom of earth.
There is 200 mile long earth replica acting as s ruler along this imaginary line of earths forward travel.

Then we imagine the 200 mile state completely passes the to scale 200 mile state replica, in one second; so that if we made a line a million miles long, and composed the line of increments of 200 mile long state replicas, then the earth would pass one pass one pass one pass one pass one pass one every second pass one every second pass one every second pass one per second pass one persecond

How to visualize this better? Make a simulation on a screen of what the 229 miles a second example, would be.

And then zoom out far, to see the earth look this big ( ) on a screen that was 100 inches big, and let that symbol cross the screen, and let every inch equal 229 miles, and let it cross each inch in a second.

Then on the same screen below this. Have a symbol like this :<>: representing a car, traveling in the same direction at 100 miles an hour,

And if each inch is roughly 200 miles;

The car would take an hour to travel half an inch, and the earth would pass 100 inches in 100 seconds?

Is this how to start to conceptualize earths speed

Someone make this animation.

Also someone make an animation with an electron traveling at a constant speed, then model what science believes the EM field surrounding the electron looks like in free uninterrupted space.

And then how it changes as 'whatever possibly can accelerate electrons' travels toward the electron, showing how the EM field is changing during this time; and then right when the electron is accelerated, again how the EM field is changing locally over the course of this action and time.

Pretty new to this board so I'm not too sure if this is the right place to ask, but what's the aerospace engineering industry like? What do you actually do during the day and how do you prevent your mind from dulling?

I just graduated from uni with a materials science degree and I'm hoping to jump into the field soon but I'm not too sure what to expect and I'm also afraid of turning into a work zombie

What is your favorite concept of species and why?

I stand on genetical concept. It seems most reliable and independent of human subjectivity.

This concept is not even stable by sex, e.g. male ligers are sterile but female ones are not.

Hybridisation is another problem with the standard concept of a species, as would >>14318899 be if that ever actually occurs. Also, you can point out that there are "mechanical" barriers to reproduction, e.g. peepee too big/small, yet artificial insemination is possible.

The concept of a species is really only useful when we talk about what happens in nature, not when humans fuck around as much as possible with organisms. What we mean by "species" is a population or set of populations of organisms which have similar characteristics and behaviours, can breed to produce fertile offspring, and actually tend to exist in stable niches with somewhat stable genomes. Because ligers and tigons can only breed with more lions/tigers, not with themselves, they don't really class as species, but as hybrids.

There really isn't a complete, concrete definition of "species" like there are definitions for mathematical or physical concepts, just good descriptions which cover almost all cases.

how did these animals get so big? Didn't they bother learning the square cube law at college? Why don't elephants grow as big as titanosaurs? Somethings not right here.
>inb4 higher oxygen rates
oxygen is for moving muscles, not for bones, and also respiration is limited by the rate of CO2 that can be expelled, not by the amount of O2 that can be inhaled: thats why u don't see athletes in controlled indoor environments with high oxygen easily breaking outdoor records.

Doctors gave them an overdose of aspirin and killed them with it.
Scientists and doctors should be rounded up and shot in the near future.
