  • Teeth cannot produce enamel. Enamel is not a living tissue and it was produced by cells outside of the tooth in a coral-like manner. In order to grow a new tooth, you need it to be fully surrounded by specialized living tissue for the whole growth cycle.

    PS: I honestly expected something like this to come out of bioelectric computation research, but progress seems slower there. Or rather knowledge and techniques in other fields is reaching critical mass, giving us these advances.






  • Teleportation in that term means “make a thing disappear in one place and appear in another”. No “immediate” is ever implied.

    Wikipedia article has a great diagram on the topic. Add an article on “no cloning theorem” to understand why “teleportation” is a fitting term. I recommend reading both without expectation, just read through the steps as if you’re learning a new math tool.

    In short, quantum teleportation is a way to take a quantum state (which are fundamentally unforgeable - you can’t simply create a clone of a particle), destroy it, extracting classically communicable data, and they recreate it in another location.


  • FTL is a weird one.

    Speed of light is a singularity in a special relativity theory. Singularities usually indicate model limitations, not reality fundamentals.

    The theory happily describes behaviours below and above this “speed limit”, but insists on it being unapproachable from either side, which is weird already. At the same time our other models tell us that matter loses a finite amount of energy when it gains mass and stops moving at the speed of light.

    Problem is, we don’t seem to have a vocabulary to discuss ways around this singularity and universe is not so forthcoming with any clues.

    It’s a general crysis of physics lately. We know our models have limitations, we often know where they break exactly, and universe just giggles along.

    But yeah, it’s highly unlikely that any SF will correctly guess a viable FTL, even if it is possible. Especially considering how seemingly every author thinks quantum entanglement is it.



  • Seems to me, you’re dealing with a micromanager.

    Personal recommendation - put things into writing. When you get your assignment verbally, write it down with assumptions you have to make to fill the gaps, and send it to the person who gave you the assignment, with the person responsible for your teams’ results in CC. Basically an “I heard you, and I’m starting the work as described below”.

    Communication is one of the most important skills in software engineering, and this way you get to practise it while probing the social waters of dealing with management.

    Try it, see how it goes, adjust accordingly.






  • You just replace that anxiety with a different fear.

    I don’t fear oblivion, I fear it will keep me waiting. Not existing is a silent matter, living past your due as a broken, diseased husk or a person is a torture to you and those you cherish.

    Death is a promise of rest, there’s no need to fear it. I’m a bit sad that I won’t get to witness most of the things I want to witness, but so be it.
