trentlott··on Ask HN: What can I do to accelerate scientific research?
...why should death be solved ASAP?

We haven't got the space or resources for exponential growth of population

trentlott··on YouTube’s anti-extremism crackdown targets journalist who documents extremism
Could YouTube provide more structure and moderate by subcatgories?

Say I say I'm an expert in chemistry and education - then I would be available to moderate chem Ed videos.

I'm not convinced this isn't an attempt by YT to claim they tried and it had unintended consequences they can't avoid.

trentlott··on My 8 year old is in debt.
The use of financial incentives often displace a genuine interest and motivation to do such things.

Be wary of applying it too broadly, I think.

trentlott··on Soul – A language and IDE for audio coding
> Our long-term goal with plugins is to make them much easier to write in SOUL without needing to actually compile anything natively

could you offer to compile/package SOUL code into a VST as a service?

trentlott··on God's Number Is 20 (2010)
A small note - is anyone else frustrated that the video can't be played in both directions?

Watching someone disorder a solved cube is not particularly interesting or satisfying. I'm sure it does serve the text, but boy it irks me.

trentlott··on The Art of Research – A History by Vi Hart
There's very little novelty in what VR provides - it just provides a significant enhancement in the experience

Also, limitations can breed efficiency - by being constrained to a 2D projection, the interactions are simplified and streamlined

VR provides the same goals and expects utility (fun, efficiency) from the process.

Its fun and interesting, but I haven't seen anything groundbreaking.

Frankly, I think VR and FB are a good match for another reason - they both provide an overwhelming, dissociating experience

This can be a boon, but like sugar and opiates I worry that they're more social or sensory information than we can take in chronically - unfortunately, huge amounts of money and thought and technology is aimed at maximizing our intake to pad coffers.

I'm not sad AR/VR adoption is lacklustre

trentlott··on Nord: An arctic, north-bluish color palette
I'm baffled why people are suddenly marketing CSS themes

Is it just a demonstration of skill?

trentlott··on Hollywood Upended as Unions Tell Writers to Fire Agents
That's fantastic, thanks!
trentlott··on Complex societies precede moralizing gods throughout world history
If everyone had 'gods' instead of an internal monologue, why would anybody care if Moses said Jehovah spoke to him?

"Who cares?" God revealed to Levi, "It happens to all of us."

trentlott··on Scientists find likely source of methane on Mars
> The most likely source was a sheet of frozen methane beneath a rock formation

While it is certainly pretty likely, it isn't necessarily known that this rock is part of methane generation.

If it's coming from the ice directly, the ice sheet 'location' doesn't explain whether the methane was from a biotic or abiotic source.

It probably eliminates the already-small likelihood that it is coming from still-extant microorganisms, but it doesn't eliminate their possible involvement in clathrate formation.

trentlott··on Mission to find never-contacted Amazon tribe to stop “catastrophic” jungle war
How and why are nations established?

Do they not get to have their own territory, or do they have less right to sovereignty than the US or Argentina?

trentlott··on Ask HN: Physicists of HN, what are you working on these days?
I think you could swing some academic or national lab position if you put some time into it.

Is there anything even tangentially related to your dayjob that you could mine for ideas? Or maybe take some time to come up with some research direction?

A places like Oak Ridge could have something interesting available.

trentlott··on The cortex is a neural network of neural networks
One of my favored arguments for maintaining as much biodiversity as we possibly can.

Each species' death is millions of years of labwork trashed

trentlott··on Scientists Watch as Heat Moves at the Speed of Sound
Yeah, that's the actual question and probably a reason why it's not an established technique

Also, low-frequency waves naturally are lower energy. Why not bury the output and increase the frequency?

It would have the added benefit of supposedly keeping away ground-dwelling pests; supposedly.

Walmart blood strip tester?
trentlott··on VFX, Amiga and Babylon 5 [video]
Well, he was apparently a member of the church - so, yes! And it was probably bordered on lust in the classical sense (and, more accurately, in the modern one).
trentlott··on Why neutrons and protons are modified inside nuclei
That's probably the right side of history anyway. Pilot wave fails in a lot of ways, but it at least allows a way to express the anxiety of thinking "is that it?! Nobody thought of a better rationalization?!"

You experience the properties of particles a little more directly...mostly in solution.

It's easy to see why pilot wave is appealing...maybe, secretly, things are actually not crazy or incomprehensible at small scales and the universe makes sense!

But even ignoring QM and looking out at the 13 billion light years of space above should make one ponder what right we had to get even this far

trentlott··on License Plate Detection Without Machine Learning
The future of computing is here!

After tiring of convoluted web 3.0 frameworks and Babel-esque dependency structures, programmers have finally fashioned a black box they cannot understand which relieves the anxiety of knowing they should.

trentlott··on Why neutrons and protons are modified inside nuclei
Yeah, I don't see pilot wave as valid. I think it's wishful theorizing from people who can't take Copenhagen.

There is also a divorcing of pilot wave from these particular visualizations - the emergent properties of fluids will always make them bad approximations. But the maths don't work out either, and it ends up getting too convoluted compared to the 'simpler' and weirder version.

However, I think it's an interesting alternative that demonstrates why, at some level, you just kind of have to throw your hands up and say "well I guess that's just how reality works, dammit."

There are less-crazy visions about how very small things work, but they don't do the job.

trentlott··on Why neutrons and protons are modified inside nuclei
You might be interested in Pilot Wave Theory. It tries to reconcile wave/particle duality by claiming there is a real physical particle at all times in an attempt to get around the strange idea of everything being a probablistic wavefunction (the Copenhagen interpretation).

It explains some things pretty intuitively (double slit experiment), but from what I can tell it becomes too convoluted for other things.

Mass can be related to energy with E=mc^2, and you can get some idea of its relation to wavelength and wave collisions.

I think a smallest wavelength is unlikely, because it would put an upper bound on energy. The only side-effect of increasing the energy density (ie a lot of energy in a small space, like a very low-wavelength photon) is the formation of a black hole. I think the question of whether photons (massless) can form them is one of those quantum-gravity issues that are awaiting a theory.

trentlott··on Why neutrons and protons are modified inside nuclei
I want to take a second to rep my absolute favorite podcast, Physics Frontiers.°

It's not a "pop-sci" podcast - they take a couple of interesting modern physics papers and discuss them; no more, no less. A lot of it is way over my head as a chemist, but that's part of what makes me love it. The topics are always understandable, even if it takes self-study to get the nuances.

One guy is a physicist and the other is a sculptor who, I assume, taught himself physics.

Just a thing that would likely appeal to one who cares about particle physics and is not well satisfied by the preponderance of 'physics' podcasts that endlessly re-explain what entropy is or what wave/particle duality means.

I wish more science podcasts dealt directly with modern research, and this one is a great example...even if they're skeptical about Copenhagen and prefer pilot-wave "realism".

trentlott··on Computer Modeling Should Become a Popular Hobby
Blender allows for the use of human units. It also contains engines for physics and lots of videos explaining how to do interesting things, including allowing for Python scripting

Choosing a very popular free platform has benefits (blender.org)

trentlott··on Computer Modeling Should Become a Popular Hobby
I mean, this was the essential point that brought about chaos theory, right?

Rounding wind speeds down at the force of a butterfly flap caused significant deviations for known weather patterns.

Having people half-ass assumptions because they read about a supply/demand curve once and can scrap DJIA data in order to gamble their 15k savings is unlikely to be widespread, but definitely something to consider if that is your argument.

However, it would still least breed familiarity. I take your point that this will probably not help things and...well, I guess I've run out of steam in my own comment.

Ignorance is bad, and staying in ivory towers will end badly. The obvious route for education will likely only foster arrogance and cynicism. What's the third way? Make everyone read Kant and write "Marx was a philosopher, not an economist" 100 times?

trentlott··on Pee, Not Chlorine, Causes Red Eyes from Swimming Pools: CDC (2015)
I vaguely remember this being a plot point in an episode of 'The Adventures of Pete and Pete'†. I'm sure there are plenty of chemists that have valiantly attempted to find something that could both stay stable in UV-blasted chlorinated water and react with a weak acid to give an absorption in the visible wavelength. . .but that is a very long and hard-to-fulfill wishlist.

Anyway, it's just any sort of amine reacting with chlorine that produces the chloramines that irritate your eyes. Even if nobody urinated in the pool, the sweat people produce would still be able to cause it. Obviously it wouldn't deplete chlorine as quickly, but it isn't that irritation only comes from urine alone.

Further, I'm more worried by this: > "We have a new parasitic germ that has emerged that's immune to chlorine," says Beach. "We've got to keep it out of the pool in the first place. We need additional barriers." - Dr. M Beach, Associate Director at Healthy Water, CDC

trentlott··on Fyre Festival Was a Huge Scam. Is Netflix’s Fyre Documentary a Scam, Too?
Not the derail the topic too much, but was that film great? It looked like an incredible piece of work and a beautiful use of technology.
trentlott··on Fyre Festival Was a Huge Scam. Is Netflix’s Fyre Documentary a Scam, Too?
Right - how do you document some subgroup without one one trying to make it into a generalizable truth about something.
trentlott··on Activision-Blizzard layoffs after reporting record results
I'm not sure that's true

Plenty of starry-eyed people enter academia. There isn't quite the same unionization gateway into academic jobs, but mostly just markers of effective work - papers, grants, etc

trentlott··on Child abuse images hidden in crypto-currency block chain
Right. And then it has to be clarified that sex is evil but violence is fine, or we have to declare as a society that writing Batman is a crime.
trentlott··on Child abuse images hidden in crypto-currency block chain
I think it comes down to whether we make illegal the creation/possession of images which do not require an existing physical subject - eg cartoon porn.

If we allow all cartoon porn because nobody has been victimized, then the above scenario is more simple - does the image originate from or use as its input an image requiring the suffering/exploitation of a non-consenting party?

This would cover fancy image-hiding methods because you would presumably run a script on some extant photo. You also wouldn't be able to paint your own copy of an abuse photo and claim artistry.

You could also say "all images of abuse, real or imagined", but Australia has shown that legislating thought-only is unproductive. It also wouldn't give much extra social benefit over a less restrictive real-only law.
