  Imagine if he had to apply for funding

  “these waves have the potential to transform how we communicate and will likely find world wide usage”

  He would actually be right unlike all the other funding applications which are largely oversold.

  If solid torus yes, if just the regular torus (surface of the solid torus) no. CD is homotopic to a circle and so is a solid torus.

• ⁨Comment⁩ on ⁨Baldur's Gayte⁩ ⁨⁨1⁩ ⁨week⁩ ago⁩:

  Even if it has thickness still homotopic to a circle. For instance a band with thickness is homotopic to a circle, you can retract along the radius to arrive at a circle that is inside the band. Similarly a plane, or a slab with thickness are all homotopic to a point.

  Note that all of these are transformations are from the space to itself. So if you want to say something like “but you can also shrink a circle to eventually reach a point but it is not homotopic to a point” that won’t work because you are imagining transformation that maps a circle not into itself to a smaller one.

  ps: the actual definition of homotopy equivalence between “objects” is slightly more involved but intuitively it boils down to this when you imagine one space as a subset of the other and try to see if they are homotopy equivalent.

• ⁨Comment⁩ on ⁨Baldur's Gayte⁩ ⁨⁨1⁩ ⁨week⁩ ago⁩:

  What you said is stronger than being homotopic. homotopic is weaker, for instance a line is homotopic to a point, By taking the straw (even if it has thickness) and just shrinking it along its longer axis you eventually arrive at a circle. If it has thickness you will arrive at a band and then you can also retract radially to arrive at a circle.

  that bird is doing its best, leave it alone OK?

• ⁨Comment⁩ on ⁨Baldur's Gayte⁩ ⁨⁨1⁩ ⁨week⁩ ago⁩:

  a torus is not homotopic to a straw though unless you take the straw and glue it at its ends

  I could not correctly predict that most of this is hype and got delusional thinking I could make some quick bucks PEOPLE ARE AFRAID OF TECHNOLOGY

  If the other kids’ parents approached this call by calling it a pocket change, I suspect they are extremely unpleasant to be around.

  lol this is actually a golden answer and that is why we need better teachers

  and that is turkish cheese

• ⁨Comment⁩ on ⁨Avocado⁩ ⁨⁨2⁩ ⁨weeks⁩ ago⁩:

  no that is the indian cheese

• ⁨Comment⁩ on ⁨I feel attacked⁩ ⁨⁨2⁩ ⁨weeks⁩ ago⁩:

  none, just neutrally observing my fastly declining physical recovery rates and wondering if it will be in the negatives 20 years later

• ⁨Comment⁩ on ⁨Your brain thinks...⁩ ⁨⁨2⁩ ⁨weeks⁩ ago⁩:

  This is how I imagine an AI would produce a mind hurdle

• ⁨Comment⁩ on ⁨Anon is an audiophile wannabe (he uses .mp3)⁩ ⁨⁨2⁩ ⁨weeks⁩ ago⁩:

  lol these companies are truly insane. they are basically trying to strangle any seed of innovation remotely related (very very remotely) to theirs out of fear of competition.

• ⁨Comment⁩ on ⁨I think we've all been there.⁩ ⁨⁨2⁩ ⁨weeks⁩ ago⁩:

  All this chart says is death is the absorbing state and we all converge there regardless of excrement consistency.

• ⁨Comment⁩ on ⁨Peak masculinity⁩ ⁨⁨2⁩ ⁨weeks⁩ ago⁩:

  I wonder if everyone converges to the same fixed point

• ⁨Comment⁩ on ⁨Anon discovers cigarettes⁩ ⁨⁨2⁩ ⁨weeks⁩ ago⁩:

  For a split second I thought this was going to be a comment about a link between smoking and breast sizes (in some weird units).

• ⁨Comment⁩ on ⁨Anon discovers cigarettes⁩ ⁨⁨2⁩ ⁨weeks⁩ ago⁩:

  Sounds pretty much like the computer games I played as a kid and how I remember them lol

• ⁨Comment⁩ on ⁨Anon discovers cigarettes⁩ ⁨⁨2⁩ ⁨weeks⁩ ago⁩:

  take a cup of coffee or tea and go with them. There are multiple modern addictions that you can choose from.

  Ask a certain person called Anne, she might have it in her archive.

• ⁨Comment⁩ on ⁨I'd choose 4 tbh⁩ ⁨⁨3⁩ ⁨weeks⁩ ago⁩:

  Mostly agree, easily can reduce it down to 4,5 modulo fine print. I don’t agree with the last if a lot of money means billions and if you want to keep it all for yourself. Wanting to own billions is a mental disease imo.

• ⁨Comment⁩ on ⁨Which one did you choose????⁩ ⁨⁨3⁩ ⁨weeks⁩ ago⁩:

  if I choose the first one four times do I become a blackhole?
