>>7850896 >where were you when gravitational waves were confirmed?
Well last time I was taking a dump, coincidentally I was also taking a dump when it was announced that the majority of the signal they detected was likely just dust. This time I'll probably be on 4chan, but I'm going to try and keep the tradition going and be taking a shit when they announce this one as well.
Why do so many people who barely passed high school science, or people who are experts in a completely different field, always have an opinion of things they literally do not have the framework to understand?
The average climate change denier or flat earther does not have the base of knowledge required to even begin to engage with the topic.
Why can't people just say "I don't know" and keep their mouths shut?
T. An engineering student that keeps his mouth shut about biology, chemistry, climatology, etc.
You might be allegedly smart on scientific topics but you are dumb as fuck when it comes to human psychology 101.
It's simply the fact that humans want attention and valdation. A natural and easy way to achieve that is to tap into the social conscious and project an image of being knowledgeable on a hot button topic.. the kind of topics that get gullible people on board and hothead idiots like you woynd.. so that the topic stats relevant. To them it doesn't matter if they are right about something or not, as long as people are paying attention to them when they... Comment too long. Click here to view the full text.
Many people on the internet claim that running on a treadmill requires the same amount of exertion as running on solid ground.
However, I don't think that this assertion is supported by physics.
First, I'd like you to consider what happens if you were to drop a runner directly on to a treadmill. If he was already moving his legs at the exact right speed, (very difficult in practice, but bear with me), he would simply run, stationary in relation to the treadmill, just as if he'd been running on it the whole time.
Now imagine dropping a runner... Comment too long. Click here to view the full text.
We can't just ignore friction (and I don't see why you'd want to). If the treadmill has better grip you will use less energy. If the ground has better grip the opposite is true. Now I don't think most treadmills have poor grip. It's a core feature.
The only reason I can see running outside would be easier is if you have the wind in your back.
And if we're just considering how exhausted you get often if you run outside you need to adjust the angle of your feet, which is energy you output. There's also the additional inefficiency... Comment too long. Click here to view the full text.
>A different definition involves what Terry Tao refers to as ultralimit, i.e., the equivalence class [(0.9, 0.99, 0.999, …)] of this sequence in the ultrapower construction, which is a number that falls short of 1 by an infinitesimal amount.

>>7850669 Well people who can't spell are more likely to be stupid, so there's that. If you don't understand the language you speak, you're also not very likely to be able to grasp the intricacies of mathematics and science.
Where can I find good Mathematics problem sums with solutions provided? My school always provides me with questions and answers only and have to make a long trip to visit the TA or professor whenever i need help which would have been saved if the solution was provided. Thanks for the help.
little disclaimer here: i don't know english well, so don't kill me instantly) problem: please help me to understand - imaginary unit - complex numbers - quaternions for what these imaginary units are made? complex numbers are just vectors? and quaternions... so difficult) why they have 4-dimensional unit to explain 3d rotation. very want to uderstand this. very,very)
