I know that in quantum mechanics, parallel universes are alternate versions of ourselves, and therefore not anime, and I know that cosmology's parallel universes are just zones of space that we can't reach if we travel under the speed of light.
But there's gotta be theories that allow things like magic to exist, right? Maybe one of the advanced ones like QCD or string theory?
Please, help. I'm studying physics in college only for this reason.
Hello, I have a question about this meme, why here instead of B we have 0 and not 1? Because the equation is ax+bx^2+c=0, knowing that there is always a 1 before the x why put 0? Thanks for your help
Looking to form a group of 6 science enthusiasts to build a secret underground lab with.
Requirements >badly wants to have an underground lair will actually commit to the project >lives on the west coast >130+ IQ >2+ years of STEM study in their respective domain >hates humanity >will never reproduce >willing to only associate with members of the group and relocate
Book says answer is 15. I got 7. The only way I could see it being 15 is by the first term -2^2 being equal to 4 instead of -4, but since there's no parentheses shouldn't you be doing 2^2 and then adding the negative sign afterwards?
I am working on a project to automate a lot of my work, but I wanted a stronger mathematical background under my belt to make sure I tackle this properly. I am a drafter that will be writing a module to select and generate the proper geometry for our models given some input data before it is seen or touched by other people. To that end, I've been trying to pick up some useful terminology to help me search for more relevant material on the topic. Let me explain what I'm trying to do:
Pic related is a simplified example of what I wish to do. We can assume that the leftmost and and rightmost profile will always be present for a particular model. The true dimensions are not what is important, it is the relational constraints that are (aka, the left is always a vertical line perpendicular to a horizontal line, each of arbitrary length). Given those two constraining paths, I wish to "attach" a intermediate open profile between the two at their respective endpoints. Once again, the relational constraints of these profiles are all that must be preserved, and the dimensions are irrelevant.
I'm not a pure math buff, and am not currently familiar with the notation common to academic publications, but it is not out of my wheelhouse to pick it up very rapidly. I have a short list of potentially useful words to look into, and I am hoping you could give me further guidance. If you can point me to the right topics to research, I can teach myself the notation and dive deeply to learn what I need for my project. Here is the surface level first pass list of keywords I've compiled: >affine geometry >configuration >Isomorphism >homomorphism >homeomorphism >continuous graph >simple path >group theory >topography
A space ship starts flying toward earth at the speed of light from 10,000 light years away.
Assuming an observer is watching where it would be coming from the whole time.
How many years before the observer can see the ship?
Tomorrow my part of the country gets its first full force Cat 1 Hurricane in almost 30 years. Next week will be our 4th heat wave of the summer with temps in the mid 90s -- shit that was unheard of even 10 years ago. Have these things happened before? Yes. But with this frequency all across the place?
What is it going to take to wake people up? Are we even able to mitigate / reverse anything at this point?
