It is not possible to see stars outside of the Milky Way by naked eye Updated +Created
The Large Magellanic Cloud stands out as the brightest thing we can see from outside the Milky Way by far!

Anything that is not in the Pali Canon has basically zero chance of having come from Buddha or his immediate followers.

Operon Updated +Created
Sequence of genes under a single promoter. For an example, see E. Coli K-12 MG1655 operon thrLABC.
A single operon may produce multiple different transcription units depending on certain conditions, see: operon vs transcription unit.
Mortal matrix problem Updated +Created
One of the most simple to state undecidable problems.
The reason that it is undecidable is that you can repeat each matrix any number of times, so there isn't a finite number of possibilities to check.
Computable number Updated +Created
There are only boring exampes of taking an uncomputable language and converting it into a number?
Special unitary group Updated +Created
The complex analogue of the special orthogonal group, i.e. the subgroup of the unitary group with determinant equals exactly 1 instead of an arbitrary complex number with absolute value equal 1 as is the case for the unitary group.

Transversal time dilation Updated +Created
Light watch transverse to direction of motion. This case is interesting because it separates length contraction from time dilation completely.
Of course, as usual in special relativity, calling something "time dilation" leads us to mind boggling ideas of "symmetry breaking": if both frames have a light watch, how can both possibly observe the other to be time dilated?
And the answer to this, is the usual: in special relativity time and space are interwoven in a fucked up way, everything is just a spacetime event.
In this case, there are three spacetime events of interest: both clocks start at same position, your beam hits up at x=0, moving frame hits up at x>0.
Those two mentioned events are spacelike-separated events, and therefore even though they seem simultaneous to you, they are not going to be simultaneous to the moving observer!
If little clock one meter away from you tells you that at the time of some event (your light beam hit up) the moving light watch was only 50% up, this is just a number given by your one meter away watch!
YOLO model Updated +Created
Object detection model.
You can get some really sweet pre-trained versions of this, typically trained on the COCO dataset.

Why Private Billions Are Flowing Into Fusion by Bloomberg (2022)

  • Joint European Torus
  • General Fusion: compress with liquid metal. Intends to demo in JET site.
  • Helion Energy: direct fusion to electricity conversion without steam, direct from magnetic field movements
  • First Light: shoot microscopic objct at a target to crush it so much that fusion happens
It is interesting that there are several different approaches to the problem. This feels a bit like quantum computing's development at the same time, increases hope that at least one will work.
JAVA_HOME Updated +Created
This ultimately determines which Java is used by a bunch of tools.
TODO is there a way to update it sanely in Ubuntu: askubuntu.com/questions/175514/how-to-set-java-home-for-java to always match the default java executable?
