(I can't tell from the post if you are able to print 2 materials, or just embed 1 in another, so I'm not sure if this is what you are looking for) At one point I wrote a STL converter for medical images (DICOM -> STL), for MRIs

I am not sure where I read the psych study (citation anyone?), but I remember reading that a really effective method for getting someone to change their mind was actually to get the other person to frame their argument as a question. E.g.,

Well, freezing/thawing will create sheer that destroys the DNA, so I think the reason is different.

by chris_va 10y ago
I'm not sure this is correct. Maybe if you completely isolate it from radiation. The human body is constantly repairing DNA damage.

Even if you can make it work, DNA stability is poor. I don't see why you wouldn't use a higher fidelity atomic storage solution.

Investors seeking profits? The horror! Profits are what caused investors to create these companies in the first place, so without that we wouldn't have EpiPens. In this particular case, there is an anti-trust argument to be made (after

Sure, but the premise here is that the population no longer trusts the government to serve their best interests, nor perhaps abide by the constitution. It's all about checks and balances. The second amendment gives some power to the pe

The "indirection" here is on the intention of the 2nd amendment, which while written to provide for gun ownership is actually intended to provide for popular revolution. Having said that, yes, I left out why a gun registry might r

by chris_va 10y ago
The argument is that a gun registry defeats the intended purpose of the second amendment, which (indirectly) is to prevent the government from stopping a popular revolution.

by chris_va 10y ago
Well, not that I agree with it entirely, but here's my understanding of the argument (which might be entirely wrong): Going way back, the 2nd amendment entitles US citizens to own firearms because it's supposed to be a government

One more thing, With pass through entities (eg LLC, K-1), you can accidentally pass on tax liabilities without disbursements. So your investors may be on the hook for taxes without receiving income. If you are ever planning on seeking inves

Ok, to clarify: Antibiotic resistance is generally spread via plasmid-mediated resistance. Overuse of antibiotics in any capacity, regardless of ingestion into humans, causes some bacteria to evolve resistance. Bacteria are promiscuous wi

What constitutes a gift is definitely a gray area, and very culturally specific. It's nice to want things to be black and white, but reality doesn't always line up.

Sorry, didn't mean to imply that your argument was wrong. For Iridium, the total bandwidth per satellite is really really low (like 28.8? Newer ones might be higher), and they had to put them slightly higher up (500 miles, I think?) to

If you can get it to he moon, may as well put it in the sun :). There is a slight problem with the x% chance the rocket will blow up at max-Q while still in the atmosphere. Plus, all nuclear waste ever generated would fit in 1 football stad

by chris_va 10y ago
Mostly fair, but... Latency to space is always going to be slower, as you are going to add a few hundred miles, and power requirements for high-bandwidth applications require large solar panels which are incompatible with low-altitude sats

The problem with communication satellites is that the technology isn't as good (throughput, latency, cost) as a ground based system, except for handling coverage gaps. Coverage gaps on the ground are slowly going away, so eventually th

Don't get me wrong, it will get there eventually, but the current market economics aren't exactly primed for explosive growth.

Everyone knows we need a direct carbon tax, it's just too convenient politically to be anti-tax. As a result, I think this is mostly a marketing problem. From the article, it looks like the current bill is "Climate Protection and

Most of the small sat stuff isn't for science work. Commercial entities want to reorient on demand, manage their own coms and antenna direction, etc. What you describe is a good idea, and how most older sats work (just not modularized)

I've seen it firsthand. It's not very impressive, sadly.

Well that was impassioned :). An unregulated free market is not the same thing as capitalism. There is nothing preventing you or anyone from developing a generic epipen, especially since it is just a plastic housing around a syringe. It jus

Yes, but that is capitalism. These companies primarily get created because investors want to see a return, the side effect is that they produce novel drugs. So, no, they probably don't need to raise prices. Because they now have a te

I understand the point you are making, but in reality drugs will get developed based on their likely risk/reward ratio only. If you want more diversity, unless there is a non-market force (which honestly shouldn't be needed here,
